Answer:
First question - Green curve
Second question - Red curve
Explanation:
Answer:
C. nudation
Explanation:
When an ecological system has been destroyed by some catastrophe, what is left is usually barren land. This barren land is not suitable for the majority of the organisms to live on it, so changes are needed. Nudation is the first process, and it is part of the primary succession. This process is actually the one responsible for the minor changes that happen on the barren land, preparing it slowly for the organisms to be able to move into it and start developing a new ecosystem.
Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
Answer:
The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature to increase the surface area for reactions (electrochemical gradient) by accommodating protons pumped into it by the proton motive force(PMF) from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.
Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.
Explanation:
The answer is; NO
This is because the leaf would not have tiny oxygen bubbles spread across its base (because the base is where most stomata are) that would help it float on the water. The reason is that the oxygen produced in the process of photosynthesis would be consumed in respiration because the rates of the two biochemical processes are the same.
