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.
The correct answer is sharp claws for climbing trees.
Animal adaptations are behavioral and physical adaptations, which assists animals to thrive and survive in their local habitats. When animals thrive in a habitat for a specific time, they ultimately establish mannerisms and physical characteristics, which assist them to work better in that surrounding.
The ground squirrels in African savannas live in underground burrows that they dig with the help of their sharp claws. The ground squirrels utilize their claws to form a better grip as they climb trees to reach and collect seeds. The claws also function as a defense mechanism to safeguard themselves and their young when they are attacked or threatened.
Answer:
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. The electrons that freed from the water are transferred to ATP and NADPh
I think it would be A because none of them can be dominant over the other since the heterozygous did not take a side.
The answer is b because gazelles face many predators and they have the ability to blend with the dry grass to not get caught and eaten by predators such as other wild animals like lions.
