Half distence on the path traveling up in the air.
Explanation:
When the ball is on thr ground there and not moving there is no potential energy or kinetic energy, when the ball is tossed into the air it will reach maximum height which is determined by how much kinetic energy it has (air resistence is important however) when the ball reaches its velocitu is 0 and all of the energy in the system is potential energy, as the ball falls to the ground that potential energy is converted to kinetic energy
If a ball is thrown straight up into the air, the kinetic energy is greatest when the distance is half on the path travelling up in the air. Thus, the correct option is D.
What is Kinetic energy?Kinetic energy is the energy associated with the body which is under motion. Kinetic energy is directly proportional to the distance, mass and velocity of the object.
When the ball is thrown on the ground and is not moving then there will be no potential energy or kinetic energy as the height and velocity is zero when the object is on ground. When the ball is tossed into the air, it will reach maximum height which is determined by the kinetic energy it has and the air resistance when the ball reaches zero velocity and the greatest kinetic energy is observed when the body attains half of the total distance on the path.
Therefore, the correct option is D.

Answer: Hey Hi Where is the question??
different types of cells in your body look and function differently. the basis for these differences is:
Different types of cells look and function differently, the basis for these differences is DIFFERENT PATTERNS of gene expression. This process (differential gene expression) leads to cell specialization.
Gene expression refers to the process by which the genetic information flows from a DNA sequence (i.e., a gene) to an mRNA molecule and finally to a protein.
In somatic (body) cells, the differential patterns of gene expression lead to the generation of different proteins and ultimately to different types of cells (cell phenotypes).
In consequence, cells are specialized to perform specific functions because different genes are being expressed.

The thin, protective mucous membrane composed of nonkeratinized stratified squamous epithelium with numerous goblet cells that is supported by areolar connective tissue is known
The conjunctiva is a thin transparent mucous epithelial membrane that lines the inner surface of the eyelids made up of goblet cells whose function is to protect the eyeball.
The conjunctiva is an almost transparent membrane that covers the white part of the eye, the sclera, and also the eyelids on the inside.
Its function is to protect the eyeball from external agents, although it also intervenes in the formation of tear components and in the immune defense of the eye.The conjunctival epithelium is a non-keratinized squamous stratified epithelium like the corneal epithelium but contains mucin-secreting goblet cells that maintain the tear layer.Therefore, we can conclude that the conjunctiva is a mucous membrane that is formed by non-keratinized squamous epithelium whose function is protective and lubricant.

Based on information from the cladogram and the data table shown below, which of the following best describes the evolutionary history of rabbits?
Claws/Nails Feathers Jaws Lungs Mammary glands
Bird X X X X
Hagfish
Lizard X X X
Rabbit X X X X
Salamander X X
Tiger X X X X
Trout X
Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to tigers than they are to birds.
They became able to produce mammary glands as a result of lacking feathers.
They evolved into a separate species due to the presence of mammary glands.
They share a more recent common evolutionary ancestor with salamanders than they do with lizards.
Answer:
A. They are more closely related to tigers than they are to birds.
Explanation:
Short answer: I took the test
Actual explanation:
-If you look at the first graphic that you have, you will notice that rabbits and tigers have all the same boxes checked off. AND birds and rabbits only have 3 checked off.
-salamanders actually have less in common with rabbits than they do with lizards, salamanders have 3 things in common, and lizards only have 2, proving option D. wrong. (if you are wondering where I got that evidence, look at the chart) AND if you look at the cladogram, lizards are closer to the rabbits than salamanders meaning that lizards have a more common ancestor (I think?) But nevertheless, it it still wrong, because of the above evidence.
- The options with mammary glands are also incorrect for these reasons, B. makes no sense, literally no sense, why would not be able to produce mammary glands with feathers, so B, is automatically out. With option C, rabbits did not evolve into a whole new species, it is the clade showing that tigers and rabbits both have mammary glands. There is no showing of a new species on the cladogram, and I don't think that it makes sense to evolve into a whole species just because of mammary glands.
- Now, if you look at the cladogram again, you wills see that tigers and rabbits are closest together, meaning that they are closely related. BUT, birds and rabbits are also the closet together, so, refer back to point a, that the chart shows that birds only share 3 out of the 4 that rabbits and tigers share. so that's that.
So after doing the work, option A. Rabbits are more closely related to tigers than they are birds. (and If you read my long explanation THANK YOU I put time and effort into it to make it accurate :))

in the gel electrophoresis lab, you determined the ________ of three different dna samples.
In the gel electrophoresis lab, you determined the genotype of three different DNA samples.
Gel electrophoresis is a process that allows you to separate fragments of DNA based on size. You place different size fragments of DNA into a gel, then apply current to the buffer surrounding the gel, the DNA will travel through the gel but move at different speeds based on the different fragment sizes. Larger fragments of DNA will move slower than smaller fragment sizes.
Let consider two different alleles:
the bigger allele -- Athe smaller allele -- aThe bigger allele happens to contain a restriction site that is allowed to be cleaved by a restriction enzyme while the smaller allele has a mutation in the restriction site that means that it will not be recognized and cleaved by that same restriction enzyme.
Let us remember that the person will have two copies of this gene and can be:
H0m0zygous dominant AAh0m0zygous recessive aaheterozygous AaAn individual with h0m0zyg0us AA only have versions of the gene that will be cut by the restriction enzymes, each allele producing a small fragment of DNA and a medium-size fragment of DNA
An individual with the genotype aa only has the version of the gene that does not have the restriction site and therefore does not get cut by the restriction enzyme. The DNA sample from this individual will have a single larger fragment of DNA.
When you isolate DNA from heterozygous Aa, half of the DNA isolated has the allele with the restriction site that gets cut into two fragments while the other half will have the allele that does not have the restriction site and remains whole when a restriction enzyme is added.
Therefore, we can conclude that in the gel electrophoresis lab, you determined the genotype of three different DNA samples.

in a neuron, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump such that __________.
Answer:
the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
Explanation:
In a neuron, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump such that the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
What is sodium potassium pump?The sodium potassium pump contributes to the maintenance of osmotic equilibrium and membrane potential in cells. Sodium and potassium move in the contrast way of the concentration gradients.
The Na+ K+-ATPase pump establish and maintain a gradient of higher sodium concentrations extracellularly and higher potassium levels intracellularly.
The sodium-potassium pump is critical to the proper functioning of neurons. It aids in the maintenance of ionic concentrations both inside and outside the cell, allowing neurons to fire action potentials, which is the basis for electrical signaling within neurons.
The sodium-potassium exchange pump maintains sodium and potassium concentrations in neurons so that the sodium concentration is higher outside the cell than inside the cell and the potassium concentration is higher inside the cell than outside the cell.
Thus, this way, sodium and potassium concentrations are maintained by the sodium-potassium exchange pump in a neuron.

What did Allan Savory notice about the lands grazed by wild animals at the Africa Centre for Holistic Management
Answer:
Allan Savory noticed that grasslands co-evolved with large numbers of migrating ruminants, and therefore are co-dependent on each other's survival. These animals grouped together and constantly bunched due to the predator-prey connection, eat the grasses following the seasons throughout their migration in arid regions (Brittleness scale, of Non-Brittle to Brittle environments).
As they move, they drop nutrient-rich dung and urine, while trampling organic litter (live or dead grasses, leaves, etc) and seeds into the soil. These actions break down materials into the surface, providing more covered soil and keeping materials from chemically decomposing (oxidation, as opposed to the fast biological decomposition that occurs in areas with consistent rainfall(Non-Brittle)). The true testament to his insights of Holistic Management re: grasslands is known as the 4th Key Insight: That time, rather than numbers governs over-grazing or over-trampling.
The important component here is that the time exposed to these animals plays the significant role in whether you have healthy grasslands, not the number of animals exposed to the area of consideration. The amount of "rest" (time) for grasses between eating or trampling is just as crucial as the time in an exposure.

these can be described as
A. autotrophs.
B. primary consumers.
C. trophic levels.
D. detritus.
Answer:
D
Explanation:
D is really decomposing waste of anytime so I think that’s the answer.
In a forest fallen leaves, dead organisms, a rotting stump. All of these can be described as detritus, hence option D is correct.
What are detritus in the ecosystem?Detritus is a term used in ecology to describe organic stuff that comes from nearby terrestrial populations and falls onto the soil or into bodies of water, including leaves and other plant parts, animal remains, waste products, and other organic trash.
Detritivorous invertebrates, which are prominent elements of almost all ecosystems, eat detritus, which is a significant pool of carbon in the global carbon cycle.
Therefore, detritus food chains, in contrast to terrestrial food chains, begin with dead organic materials rather than producers or autotrophs, hence option D is correct.

DNA is coded to RNA, which must travel from the nucleus to the cytoplasm to be read. Why does the cell need to transcribe the DNA into RNA rather than copying the DNA directly?(1 point)
DNA requires too much energy to code; building RNA is more efficient.
DNA cannot be copied; it must be translated to RNA and then back to DNA.
DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.
DNA cannot be read by ribosomes; they can only read RNA.
Answer:DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded.
Explanation:
DNA is double stranded and cannot fit through the nuclear membrane; RNA is single stranded. DNA could get damaged because of the osmotic nature of cytoplasm. Therefore, option (C) is correct to mitigate he damage.
What is transcription?The proteins are produced by cells by the transcription and translation of certain genes from their DNA into molecules of messenger RNA (mRNA), chains of amino acids, and finally fully functioning proteins.
The DNA would need to go to the cytoplasm in order to directly make proteins. Because of the osmotic properties of cytoplasm, DNA may become damaged during the translocation process. The cellular machinery does not directly make proteins from DNA in order to reduce the harm.

According to the food chain shown, about how much energy from the grasshopper trophic level is transferred to the frog trophic level?
The amount of energy transferred to frog is 10% of the energy contained in grasshopper.
This is a representation of energy levels and distribution in a food chain in an Ecosystem. When a group of organism represent the same level in a food chain, in an ecosystem ,this is trophic level. Food chain represent a linear representation of nutrients and therefore energy distributions in an ecosystem.
Basically, in an ecosystem, there is always reduction in energy transfer from one trophic level to another by 10%. This is because, as the energy is transferred from the producer (green plants) to the primary consumer, the hopper, only 10% of the available energy will pass through to the hopper because 90% of the energy will be used by the green plants for metabolic and other physiologic activities. As this is transferred to the next trophic level, the Frog, this will be reduced (for the same reasons) so that 10% of the energy received by the grasshopper is transferred to the frog.
Practically, if 100,000Kcal of energy was obtained by hopper from the primary producer,10,000kcal(10%) of 100,000 will be transferred to frog.
This 10% occurs at each trophic levels.
