what was explained by darwins theory of biological evolution
Answer:
When Organism A has a trait that negatively impacts it, or lacks a trait which would positively impact it, then said organism perishes, and its genes are not passed onto the next generation. On the flip side, when Organism B has a trait that positively impacts it, or lacks a trait that would negatively impact it, then the organism thrives, and its genes are passed onto the next generation.
Therefore, the next generation receives genes from Organism B and does not receive genes from Organism A. So, the next generation has traits that positively impact it and lacks traits that would negatively impact it, thus evolving according to Darwin.

when are chromosomes (dna) copied?
Answer:
Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.
Have a good day. :)
Answer:
Chromosome replication
Explanation:
Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.
During a study session about evolution, one of your fellow students remarks "The giraffe stretched its neck while reaching for higher leaves, its offspring inherited longer necks as a result, which statement is most likely to be helpful in correcting this students misconception?
a) characteristics acquired during an organisms life are generally not passed on through genes
b) spontaneous mutations can result in the appearance of new traits
c) only favorable adaptations of survival value
d) disuse of an organ may lead to its eventual disappearance
Answer: Characteristics acquired during an organism's life are generally not passed on through genes.
Explanation:
The most common misconception between students which can be corrected is that the characteristics acquired during an organisms life are generally not passed on through the genes. Thus, the correct option is A.
What are acquired traits?Acquired traits or characteristics are the non-heritable changes in the function or structure of a living organism which is caused after birth and was absent before this. Occurrence of acquired traits could be due to disease, injury, accident, deliberate modification, variation, repeated use, or other environmental influence.
For example, the giraffe stretched its neck while reaching for the higher leaves but her children does not get a long neck by birth however this character has been fixed with time because of the repeated use of the neck for food.
Therefore, the correct option is A.

An eastern screech owl, a carnivore, might compete with which organism most intensely for resources?
A. hawk (secondary consumer)
B. mountain lion (secondary consumer)
C. wren (primary consumer)
D. mouse (primary consumer)
Answer:
The answer is A
Explanation:
Let us take a look at the owl, it is a kind of carnivore, so it must be a secondary consumer(btw, primary consumers are herbivores). So we can eliminate answer C and D. The competition between the same species for this situation is the most intense one, so we can eliminate answer B as well, since hawk and owl are all birds. So the answer is A.

1. How do radiation, conduction, and convection affect the atmosphere?
2. How does greenhouse effect warm the earth?
Answer:
1. radiation, conduction and convention all play a roll in moving heat between earth's surface and atmosphere because since air is a poor conductor, most energy transfers by conduction occuring right near the earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere. convection works to heat the troposphere. Durring the day, the sun's radiation heats the earth's surface. the land becomes warmer than the air. Air near the Earth's surface is essentially warmed by both radiation and conduction.

2. One effect of the Hedgehog gene is to make cave tetras go blind. What is another effect it might have?
Answer:
these are odd questions....
Explanation:
1. they are curious about how they get blind
2. the quills
Answer:
1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."
2. Another effect it might have is to improve cave tetras' sense of smell.

Who ever Answer this right will get brainliest
Answer:
See Explanation
Explanation:
Pathogens are disease causing organisms in the body. They attack diverse cells, organs, tissues and systems in the body thereby causing them to malfunction (to become diseased).
Antibodies are the body's natural protective mechanism against pathogens. Antibodies engulf these pathogens and digest them. Then they produce certain chemicals called antitoxins which now destroy the toxins produced by these pathogens in the body.
Also they activate the systems involved in fighting pathogens by punching the cell wall of invading pathogens.
What is the difference between a missense mutation and a silent mutation?
Danke schon! Ilysm <3
Answer:
Answer is in explanation
Explanation:
A silent mutation is a mutation in which a single nucleotide base is changed, but that change does not effect the amino acid sequence. A missense mutation is a point mutation in which a single nucleotide is changed, resulting in a codon that codes for a different amino acid.
The mutation is caused by the exchange of one base pair if no change in the overall protein (silence mutation), if there is change in one amino acid (missense mutation).
What is a silent mutation?A mutation is a difference in the DNA sequence of an organism.
Silent mutations happen when the difference of a single DNA nucleotide within a protein-coding portion of a gene does not influence the sequence of amino acids and the protein.
Thus, silent mutation has no change whereas stop mutation leads to termination of protein.

Suppose 10,000 units of energy are available at the level of the plants . How many energy units would be passed from the frog to the snake ? A 100 units 10 units C 1,000 units D 10,000 units
Answer:
10 Units
Explanation:
If you makes an energy pyramid the energy from the plant to the organisms would be
plant (10,000) --> grasshopper (1000) --> frog (100) --> snake (10) --> eagle (1)
If 10,000 units of energy are available at the level of the plants, then one can estimate that the amount of energy available at the level of the frog is 1000, and then at the level of the snake it is 100 kJ, which is in option A.
The transfer of energy between trophic levels is known as energy flow, and in an ecosystem, the primary producers, such as plants, are at the first trophic level, followed by the primary consumers, such as herbivores like the frog, at the second trophic level. The secondary consumers, such as predators like the snake, occupy the third trophic level, as here the third one is the snake, and it will get 10% of the frog.

Which surface was warmer during the month of October? The pond or the sidewalk?
Answer:
The pond was warmer during the month of October.
Explanation:
Water has a high specific heat capacity, therefore more heat is required to change its temperature. This is why aquatic life is able to stay alive even when temperatures drop drastically. The sidewalk however, will more than likely adapt to the temperature change quickly as concrete does not have a very high specific heat capacity.
