Natural selection can cause micro evolution, or a change in allele frequencies over time, with increase fitness alleles, that becoming more common in the population over generations.

<u>Explanation:</u>

NATURAL SELECTION:

Natural selection is refer to how the offspring organisms or particular genotype or phenotype steps into  the next generation. It  lead to changes in the allele frequency; natural selection can causes small number of evolution and  that causes allele frequencies changed  for long  time; and  the increases in  the allele becoming more common in the population over generation;  

ALLELE FREQUENCY:

Natural selection, genetic drift, mutations, genetic flow are the four factors that changes the population generation. This made the natural selection leads to change in the allele frequency.

Answer:

Allele frequency can be described as a phenomenon which measure how common an allele is in a particular population. It tells about the genes which are richest in a gene pool and it also shows the genetic diversity in a population. Allele frequency is often expressed in percentages.

Natural selection tends to favour those organisms that are best adapted to live in an environment and which can withstand changes occurring in the ecosystem. If due to some circumstances, a trait becomes less useful to organisms in a population then by natural selection the allele frequency for those alleles will reduce with time. Similarly, the alleles which code for better genes for an environmental change will be increased due to the phenomenon of natural selection.

What type of communication coordinates actions between neighboring cells?
bija089 [108]

Answer: A. Chemical signal

Explanation:

Chemical signal is the type of communication which coordinates actions between neighboring cells .

This ability originated in single cells organisms and was essential for the evolution of multicellular organisms because after a cell receives a message, it is transferred across the plasma  membrane and  changes  are brought about within the cell in response to this message.

What protein is responsible for the initial step in unwinding the DNA helix during replication of the bacterial chromosome?
maw [93]

Answer:

Proteins play a fundamental role for life and are the most versatile and diverse biomolecules. They are essential for the growth of the organism and perform a huge amount of different functions.

The passage of DNA to proteins begins with the step of transforming genetic information into an intermediary between DNA and protein. This intermediary is called messenger RNA (mRNA). The difference between DNA and mRNA is that the second corresponds to a very small fraction of all DNA, consists of a single chain (it is no longer a “zipper” but a strand), and that Thymine (T) is replaced by the Uracil (U). This fraction corresponds to the stretch of DNA that contains the sequence necessary to ultimately synthesize the protein.

Identify two ways in which animals can reduce the intensity of intraspecific competition
MrMuchimi
Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food.
