Answer:
V≈904.78cm³
Explanation:
The volume of a sphere with a diameter of 12 centimeters is 904.78cm³.
Formulas: V=4/3πr³ and d=2r
V=1/6πd³=1/6·π·12³≈904.77868cm³
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.
I believe it’s B but I’m not sure sorry
Answer:
PFK
nucleus-->cytoplasm-->ER (ribosomes, translation will occur)-->Golgi body(for packaging)-->cytoplasm (specified compartment inside the cell)
insulin
nucleus-->cytoplasm-->ER (ribosomes, translation will occur)-->Golgi body(for packaging)-->outside the cell.
Explanation:
considering PFK (Phospho Fructo Kinase), for the nucleus the mRNA will be transferred to the cytoplasm on the (RER) rough endoplasmic reticulum the mRNA will be translated on ribosomes, then the packaging will be done inside Golgi apparatus, and then the protein inside the vacuole will be transported to the specialized compartment. in the case of insulin the process will be same but the desired target will be blood hence it will be transported out of the plasma membrane of islets of Langerhans into the blood capillaries.
The left side of the heart is receiving blood from the lungs via which has just been replenished with oxygen
The right side of the heart is receiving blood from the body via which has used up the oxygen.
