Um... cytokenesis is the final stage...
1. The correct answer is option A
The thickest layer is Dermis which is made up of two layers papillary and reticular. The reticular dermis is the lower layer of the dermis and is made up of dense irregular connective tissue featuring collagen fibers.
2. The correct answer is option E
Bone is composed of fibrous and mineralized connective tissues which is enriched in collagen and calcium phosphate.
3. The correct answer is option C
Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. These two filaments slide over each other to repetitively contract the muscles.
convergent evolution - called analogy
a potential source of confusion in constructing a phylogeny is similarity between organisms that is due to convergent evolution - called analogy - rather than to shared ancestry. thus for mammals, the backbone is a shared ancestral character, a character that originated in an ancestor of the taxon
Answer:
b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.
Explanation:
Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.
