The answer would be "<span>Cyclins are proteins that regulate when and how often a cell divides". Cyclins belong to a family of proteins that control the progression of a cell through its respective cell cycle. This is initiated by activating cyclin-dependent kinase (CDK) enzymes which regulate </span>transcription of RNA and process mRNA during mitosis.
A: That answer is illogical at best
B: It makes sense, the smaller you are, the less food you need
C: This would need extensive studying of key deer ancestry to figure out
D: This could work over thousands of years. But an overpopulation of one wouldn't push out the other. Ungulates (hooved mammals) of different species often work together.
B, sounds like your best choice.
It means that two chromosomes
have the same genes, or variations fo the
same genes at the same loci on the chromosomes. Variation
of the same gene is what makes up
alleles. Homologous chromosomes
are similar in size and structure. In
diploid organisms, each chromosome in the pair is derived from each parent.
A biome is a group of ecosystems which shares the same characteristics. The world is split up into several biomes such as freshwater, marine, desert, forest, grassland, and tundra.
The grassland biomes are the regions which are dominated by grasses, often 3 to 6 feet tall at maturity. They may have an open shrub layer and the climate is temperate or tropical.
