Answer:

<em>Evolution</em>

Explanation:

Evolution can be described as the changes which occur in a population over a period of time. Over a period of time, organisms tend to evolve those characteristics which make them better adapted to live in an environment. Such changes which occur over a long period of time are termed as evolution. Charles Darwin was the scientist to bring forward the theory of evolution.

The change in the tail length of a rat over a course of many years is an example of evolution.

The atomic mass of an element is equal to the:
arlik [135]

The answer should be the third option "number of protons and neutrons." The atomic mass of a element is equal to the amount of protons, and neutrons added together in that element. So for example if we are trying to find the atomic mass of hydrogen you would add the total amount of protons and neutrons together to find it's mass although it doesn't equal the exact amount of it's mass but it's close.

Hope this helps.

During meiosis I, _____________________. Group of answer choices homologous chromosome pairs are separated the chromosome number
spayn [35]

Homologous chromosome pairs are separated

Meiosis 1 refers to the initial stage of meiosis where one parent cell divides into two daughter cells. This stage is where homologous pairs of chromosomes will segregate and separate from each other and move into the two daughter cells which result in the division of the total chromosomal number by half.

<h3>What happens during Meiosis 1 ?</h3>

Meiosis I ends when the chromosomes of each homologous pair arrive at opposing poles of the cell.

  • The microtubules disintegrate, and a new nuclear membrane forms around each haploid set of chromosomes.

  • The chromosomes uncoil, forming chromatin again, and cytokinesis occurs, forming two non-identical daughter cells.

MissTica

Answer:

It is likely that the genomic sequences that were used did not enable to properly observe the evolutionary relationships among the species analyzed

Explanation:

The homology level between the genomic sequences may be too low to separate species that are phylogenetically related. In these cases, it is necessary to make a genetic analysis of the sequences that are used before the phylogenetic analysis

svlad2 [7]

Refined grain products like bread, flour tortillas, white rice, cornmeal, crackers etc are enriched with riboflavin, niacin, iron and thiamin.
