Answer:
Hydrolysis is a process in which polymers are brokendown into monomers
Explanation:
Macromolecules such as carbohydrates,proteins,lipids and nucleic acids are important components of the body cells. These components are important for an organism to survive and grow.Most macromolecules are polymers. A molecule of polymer is formed by binding of many smaller molecule called the monomers. These simple monomers linked together to form a complex polymer. The polymers and monomers are typically found the sugar. The monomers are bind together into long chain called polymers.But lipids are not polymers because they built by different monomers which resemble each other in their composition.
it should be C. scientific
Answer:
It could be prevent Ga from binding to the epinephrine receptor.
Explanation:
Hindering GTPase action will make G-protein to tie to adenyl cyclase for all time so Glucose is delivered persistently.
Diminishing the proclivity for GDP will build the opportunity of authoritative of GTP to G protein which thus will initiate the pathway.
On the off chance that G protein ties with adenyl cyclase it will invigorate it.
Yet, in the event that the G-protein is kept from official with epinephrine receptor, at that point the receptor can't enact trade the guanine nucleotide to G-protein for initiation. Thus the G-protein stays in latent state.
The question is incomplete as it does not have the options which are:
A. The threefold change happened in one concentrated burst.
B. The change was not consistent in direction, but happened in multiple bursts concentrated at each speciation event.
C. There was consistent directional selection toward a larger brain all along the lineage between the two species.
D. None of the above.
Answer:
Option-B
Explanation:
The hominids evolved with time and the known hominid in modern time is the Homo sapiens or modern human.
The Homo sapiens like other species could have evolved from the older species through speciation and studies suggest that one of the major factors of human evolution is the size of the brain.
Two possibilities could explain the size of the brain that it could have evolved slowly with time called the gradual equilibrium or in bursts concentrated at each speciation event.
Since the punctuated equilibrium takes place in bursts until the species reach stasis is the most applicable condition for punctuated equilibrium to happen therefore Option-B is the correct answer.
