Will the fossil record ever be complete?

Today, through over a century of study of both the Earth's surface and the completeness of the fossil record, paleontologists have been able to determine that while the record will never be complete and always has preservation biases, we often have more than enough evidence to draw strong evolutionary conclusions about ...

larisa86 [58]

The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.

<h3>What is fitness?</h3>

Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.

Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.

It is a way of measuring the individual ability to leave fertile offspring.

Aptitude must be significant to the natural selection act in its favor.

In the exposed example we can see the survival rate of two species.

The survival rate is telling us about the fitness of each species.

  • The green beetle increases its survival rate (fitness) each year
  • The brown beetle decreases its survival rate each year

These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

Mrna,amino acids,type of mutation
Leya [2.2K]

Answer:

mRNA: 3' AUG-AAU-GCU-GCC-GGU-GA-5'

amino acids : methionine, asparagine, alanine, arginine, proline

type of mutation: deletion, missense

Explanation:

The mRNA sequence is complementary to the DNA sequence. A always pairs with T, C always pairs with G. Except this is an RNA sequence not a DNA sequence, so T is replaced with U.

The mRNA sequence is translated into an amino acid sequence based on the triplet code. The triplet code for this sequence is shown in the attached picture. Each triplet signifies a specific amino acid. The codon can be identified from the table and placed in sequence. We can see that the new DNA strand has caused a new amino acid sequence. It has also left us with an incomplete sequence, as GA cannot signify an amino acid.

The type of mutation is a single base deletion. We can see that the base C is missing from the 9th amino acid in the original strand. As you can see, this has an ongoing affect on all the bases in the rest of the sequence, as it changes the way the sequence is organised into codons. This results in a missense mutation.

At which point in mitosis does a cleavage furrow form?
Aliun [14]

In cell biology, the cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division.
