Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are proteins called histones.
<h3>
<em><u>They act as packaging elements for the DNA.</u></em></h3>
The reason that chromatin is important is that it's a pretty good packing trick to get all the DNA inside a cell.
Answer: A. By selecting dominant genotypes
Explanation:
Artificial selection or selective breeding can be defined as the induced breeding process in which humans select parents of plants and animals that have desired traits that are beneficial for them to produce offspring that have characteristics of both parents and they are of improved yield and quality. This brings the change in the phenotypes of the offspring as compared to the parents. As the passage of dominant desirable traits in the genotype from either of the parent when gets expressed then the phenotype of the organism also change.
The answer to this question is A because all living plants have chloroplasts to use photosynthesis
Answer:
D.
Both the femur and humerus bone have what's called 'spongy bone' inside them and hollow spaces full of yellow and red bone marrow. Additionally, both bones do not attach to the axial skeleton but rather attach to the pelvic or hip bones; while they are both strong bones, they are not made of only compact bone but are made of 'spongy bone' inside them. Lastly, they do not protect any organs but rather allow for movement. D, They both have hollow spaces filled with bone-generating cells, is the best answer in this case
Explanation:
The correct answer is D.
