Sea otters are a symbol of the beauty and diversity of marine life that can be found along the California coast.
They're also important to the health and stability of coastal marine ecosystems, hence they're considered critical species.
Sea urchins and other invertebrates that graze on giant kelp provide food for them.
Without sea otters, kelp forests and, with them, a variety of animal species that rely on kelp environments for existence would be destroyed.
Kelp forests also safeguard the coast from storm surges and absorb a significant amount of dangerous carbon dioxide from the atmosphere.
Sea otters are especially important since their health reflects the health of the coastal waterways of California.
Answer:
Number 2 is false
Explanation:
an enzyme cannot do that.
As both the genes get equally expressed in the human blood group genes, both the proteins or characters expressed by those genes get prominent in the phenotype of the organism.
<h3><u>
Explanation:</u></h3>
In case of human blood type, there are co dominance between the genes coding for A blood group and B blood group. Absence of both of them produce the O blood group and presence of both of them produce the AB blood group.
The gene for A blood group codes for enzyme α-1,3-N-acetylgalactosamine transferase which attaches the N Acetylgalactosamine to surface of RBCs which are actually the A antigens.
The gene for B blood group codes for α-1,3-galactosyl transferase which attaches galactose to surface of RBCs which are actually B antigens.
Presence of both of these genes make both N Acetylgalactosamine and galactose to be present on RBC membrane. This is why co dominance occurs in case of AB blood group persons.
