This was simulation. What are some variables that this peppered moths simulation does not address?

Answers

Answer:

The simulation only shows how a population can change overtime in response to the changes in the environment. During the industrial revolution, one particular phenotype of moths had an advantage over the other and hence, was subjected to natural selection. What this simulation does not tell us is the causality and correlation aspect of the change that occurs in the moths. Correlation does not equal causation, and the simulation does not shed any light on these variables in this case.

Example of how organisms that were previously thought of as related are actually more genetically related to organisms outside their species?

Answers

Answer:

Explanation:

Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.

But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.

A skateboard manufacturing company has had problems with the wheels on its skateboards cracking and causing injuries. An engineer for the company knows of a material that he thinks will make the skateboards safer. What would be the best step for the engineer to take next?
He should publish a report about the innovation and its impact on public safety.
He should conduct tests using computer models to determine the safety impact.
He should immediately begin producing all skateboards with the new material.
He should convert production of half of the skateboards to use the new material.

Answers

Answer:

He should conduct tests using computer models to determine the safety impact.

Explanation:

The other ones either use the material without testing it to make sure it is safe first or publish a report without knowing it's impact on public safety

Recombinant DNA technology is possible because all organisms
O A. rely on ribosomes to assemble proteins
B. have some of the same genes
C. use the same codes for amino acids
D. replicate DNA before cell division

Answers

Recombinant DNA is possible because all organisms use the same codes for amino acids. Option C is the correct one.

The genetic codes

One of the fundamental characteristics of the genetic codes is that they are similar in all living organisms.

Each genetic code is translated into an amino acid. Thus, living organisms use the same codes for their amino acids in the proteins.

This makes inserting the genes of one organism into the genome of another (recombinant DNA) very easy.

Answers

Answer:

B. A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots.

A group with 30 DD parrots, 40 Dd parrots, and 30 dd parrots is most likely in Hardy-Weinberg equilibrium.

What do you mean by Hardy-Weinberg equilibrium?

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.

Answers

Answer:

1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism. 

4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.
