Differentiate Monocots and Dicots
Answer: Monocot and Dicot
Explanation:
Monocots are seeds which have only one cotyledons. Plants having monocot seeds have parallel venation leaves (like lines running down the leaf). These seeds cannot be broken open. Dicot are seeds that have 2 cotyledons. Plants having dicot seeds have reticulate venation leaves (like veins). These seeds may be opened in two halves.
if a homozygous tall plant (aa) is crossed with a homozygous small plant (aa), knowing that tall plants are dominant over small plants. what are the resulting genotypes and phenotypes for the f1 and the f2?
25% of the heterozygous pass are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will continually show the dominant trait (phenotype), because they are heterozygous.
In this explanation, I'm assuming that the allele "T" for tall vegetation is dominant to the allele "t" for short plants, like in Gregor Mendel's pea plant experiment.
A homozygous tall pea plant will have the genotype "TT" and a homozygous quick plant will have the genotype "tt" because homozygous capacity that both alleles are identical. Since "T" is dominant over "t", any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is.
Each of the offspring has one "T" allele, so they are all tall plants. This is because the "T" allele is dominant over the "t" allele, so a plant with one "t" allele and one "T" allele will solely display the features of the "T" allele, which in this case is a tall pea plant.
The "TT" and "Tt" crosses each have at least one "T" allele, so they are tall plants. However, the closing pass "tt" would not have any "T" alleles and is short, because it is homozygous recessive . Since 1 out of four pea vegetation are short, or 1/4, the chance of a quick pea plant from a heterozygous pass is 25%.

Oxygen from the respiratory system is delivered by the circulatory system.
What is the relationship between respiratory and circulatory system?The respiratory system is responsible for delivering oxygen to the circulatory system that is made up of blood vessels which carry blood to the heart and then all cells of our body. Arteries carry blood that is loaded with oxygen from the heart to all cells whereas veins carry deoxygenated blood back to the heart and then to the lungs for disposing carbondioxide. The circulatory system carries oxygen and nutrients to the cells, and removes waste products such as carbon dioxide.

In the field of ecology, abiotic factors can be described as the non-living components of an ecosystem. When an organism reacts to these abiotic factors such as light, temperature, and sound then these are perceived as stimuli.
A stimulus is a change in the environment that is detected by the sensory receptors. A signal is carried through these receptors to the central nervous system (CNS).

Vertebrates are most closely related phylogenetically to a group of animals called tunicates and lancelets.
According to the chordate family tree, the physical characteristics of vertebrates are very much similar to tunicates and lancelets.
Lancelets are elongated and small marine invertebrates while tunicates are marine invertebrates with a hard and rubbery outer coat.
The family tree of chordates shows that vertebrates have come similarities with tunicates. However, the notochord disappears in adult tunicates while in vertebrates, the notochord is replaced by a backbone in the adult stage.

You are searching for a mutant cell that is defective in protein glycosylation. You would most likely find such a mutant by looking for cells with defective Golgi apparatus.
The Golgi apparatus can be described as a stacked membrane that plays an important role in the modification of proteins inside a eukaryotic cell. A protein after translation needs to be packaged and processed in order for it to move out of a cell. The Golgi apparatus is the site where protein modification and packaging occur.
One of the most important modifications after the translation of proteins that occurs in the Golgi complex is the glycosylation of proteins. If a cell has a mutation due to which protein glycosylation is being affected, then this means that there is a problem with the functioning of the Golgi apparatus due to this mutation.

O
B. Air temperature decreases.
C. Air temperature does not change.
D. Air temperature depends on the amount of organisms in the area.
Sry I didn’t know what subject to do for this question cause there was no earth science
The correct option is B.
The air temperature decreases when altitude increases.
When there is an increase in elevation, there will be less amount of air above us. Thus the amount of pressure decreases. Since the pressure decreases, air molecules will be spreading out further due to the expansion of air, and gradually the temperature decreases.
There will be variations of temperature with altitude which will as in the case of the troposphere, the temperature will decrease due to increasing altitude. In the stratosphere, the temperature will be increasing generally as the altitude increases due to the greater absorption of ultraviolet radiation by the ozone.
The basic idea of decreasing air temperature with respect to increased altitude is that as so far away you get from the space of earth, the atmosphere gets thinner. The total heat content included in a system is directly related to the amount of matter present, so due to this, it is cooler at increased elevations.

Water makes up approximately 60% of the human body and plays a vital role in regulating body temperature. Which property of water allows it to prevent large fluctuations in body temperature?.
Water has a high heat capacity, or the ability to "hold on to" heat well; this property aids in the regulation of body temperature in both organisms and cells. Sweating is another way that water can be used to cool down an overheated organism.
Warm-blooded animals employ water's high heat capacity to more efficiently distribute heat throughout their bodies.Water works like a car's cooling system, moving heat from warm to cold areas and allowing the body to maintain a more constant temperature.The body requires water to maintain temperature because it is a good heat conductor and absorber.

why is the δg of atp hydrolysis in the cell about twice as great as the δg of atp hydrolysis in a test tube under standard conditions?
The δg of ATP hydrolysis in the cell about twice as great as the δg of ATP hydrolysis in a test tube under standard conditions because in the cell the reaction is catalyzed by enzymes whereas in the test tube the reaction occurs on its own (spontaneously).
ATP hydrolysis is the reaction in which the breakdown of ATP occurs. This breakdown releases energy which is then used by the various processes of the body. This energy is due to the high energy phospho-anhydride bonds in the ATP.
Enzymes are the biological catalysts that fasten up the rate of reaction. This increase in the rate of reaction is fur to the reduction in the activation energy of the chemical reaction.
