Evolution of life is what Charles Darwin elucidated in his Origin of Species which was partly a summary of his observations on his lengthy trip to South America. Basically, it is whereby all organisms whether plant or animal exhibit variations such as keener vision, ability to run more rapidly etc and the variations that are beneficial to the organism that help it to survive especially in changed environments are naturally selected and after some time the organisms with the beneficial varieties become new species.

If the food on the island is small seeds, what finch is best adapted? Explain why
jeka57 [31]

Answer:Adaptation in Darwins Finches. Beak depth, which is correlated with body size and the ability to crack larger seeds, varies according to drought conditions: plants produce fewer, harder seeds in dry years and more, softer seeds in wet years. Only larger birds with deeper depths survive in drought years.

How does independent assortment during Metaphase 1 help produce diversity in gametes (eggs and sperm)?
Svetach [21]

Answer:

a. There are different possible ways that homologous pairs might line up

c. Different alignments of homologous pairs will cause different combinations of alleles in gametes.

Explanation:

The law of independent assortment, proposed by Mendel, states that the alleles of one gene segregate into gametes independently of the alleles of another gene. This means that the segregation of one gene does not affect another. This law of independent assortment is evident during gamete formation in sexually-reproducing organisms know as meiosis. Specifically, in the Metaphase 1 stage of meiosis 1, homologous chromosomes (similar but non-identical chromosomes received from each parent) lines up at the metaphase plate (cell equator).

The lining up of chromosomes in this stage occurs randomly making it possible for chromosomes to align in different possible ways. The way/manner the chromosomes align at the equator determines which chromosome combination gets separated into which gamete. The homologous chromosomes are randomly distributed at the cell's equator before segregates into gametes. This random orientation enables the alleles of each gene on a chromosome to combine in different random ways, hence, allowing genetic diversity in the resulting gametes (sperm and egg) they get segregated into.

Which of the following could be caused by a decrease in carbon fixation?
sleet_krkn [62]
<h3><u>Answer</u>;</h3>

An increase in the total biomass of consumers in the world

<h3><u>Explanation</u>;</h3>
  • Carbon fixation is the process through which carbon dioxide is removed from the air and incorporated into an organic molecule.
  • Carbon fixation occurs during the light independent reaction of photosynthesis and is the first step in the C3 or Calvin Cycle.
  • The Calvin cycle uses the energy from short-lived electronically excited carriers to convert carbon dioxide and water into organic compounds that can be used by the organism.
