If two heterozygous parents mate, the phenotypes of the resulting offspring will be 75% dominant and 25% recessive
If thats the question, Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
Explanation:
Insects do not have lungs, nor do they transport oxygen through a circulatory system in the manner that humans do. Instead, the insect respiratory system relies on a simple gas exchange that bathes the insect's body in oxygen and expels the carbon dioxide waste.
Unlike the closed circulatory system found in vertebrates, insects have an open system lacking arteries and veins. The hemolymph thus flows freely throughout their bodies, lubricating tissues and transporting nutrients and wastes.
Answer:
What is carbon
Explanation:
The Chemical Basis for Life. Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.
Carbon is the only element that makes up every living thing.
Answer:
CDK is inactive without a cyclin bound to it.
Explanation:
CDKs are the cyclin-dependent kinases. These protein kinases serve to regulate the various stages of the cell cycle. Cyclins are the regulatory proteins. The levels of cyclins fluctuate during the cell cycle. Cyclins bind to respective CDKS to activate them. Unless cyclins bind to CDKs, these protein kinases are inactive. Cdk associates with cyclin and forms a cyclin–Cdk complex. For example, mitosis specific Cdk bind to cyclins and activated M-Cdk then activates the proteins that facilitate mitosis and inactivate the one that inhibits mitosis.
