Answer:
C. Increased Aquatic Plant Population
Explanation:
If the wolves eat the beavers than there is less beavers. If there is less beavers than there are more aquatic plants.
Answer:
smooth was dominant over that for wrinkled
Explanation:
In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.
Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of North America, Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and Orinoco basins of South America, Himalayas and western ghats of India and Andaman and the Nicobar Islands.
Answer:
The chromosomes have coiled and become more compact.
Explanation:
Answer:
The barrier functions to regulate the chemical composition of the extracellular fluid surrounding the brain cells.
Explanation:
Blood-brain barrier
It is a very selective semipermeable membrane , hence allow some specific substance to pass via it . This barrier separates the extracellular fluid in the central nervous system and the circulating blood from the brain .
<u>The barrier is composed of the endothelial cells .</u>
Passive diffusion is shown in this system , and allows molecules like the water , glucose , amino acid to pass .
It regulates the chemical composition of the fluid of brain cell .
