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:
<span>The independent variable is the variable that does not change despite inputs. In this experiment, the independent variable is the color of mashed potatoes. The control group is what the experimental group is measured against to determine how much change there is. Plain potatoes is the control group. Number of samples is how many different opinions are taken into account. In this instance, the number of samples is equal to the number of students, or 100. There are no repeated trials. She only did the experiment one time.
The hypothesis is what the experimenter believes will happen. Gloria did not state the hypothesis for the experiment. She could have said, "I believe that students will choose colored mash potatoes than plain."
This experiment can be improved by repeating the experiment at more schools. Also, it can be improved by increasing the number of students tested.</span>
Answer:
I will receive a whole organ with extra cells to produce insulin.
Explanation:
The maintenance of glucose level in the body is important and the levels are maintained by the hormone insulin and glucagon. The abnormal secretion of insulin in the body is responsible for the diabetes in the individual.
The patient has undergone the islet cell transplant. The transplanted cell lose their function over time. These insulin cells remain in function for 2 years. Later the insulin amount and its frequency of administration reduces with time because blood glucose levels get improved. This islet transplant is not responsible for curing the diabetes. Hence, the transplant of whole organ requires for the cells to produce insulin.
Thus, the correct answer is option (a).
Answer:
The correct answer is - DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
Explanation:
The chromatin reticulum is present in the undivided cells, which condenses to form a rod-like form called a chromosome. The chromosome consists of DNA structures.
That DNA is a double helical structure and acidic in nature and it is present inside the chromosomes as it is coiled around histone protein which is basic in nature. That allows the DNA to fits in the nucleus.
Thus, the 3rd statement is the correct answer.
Answer:
False.
Explanation:
Osteons does not run perpendicular to the diaphysis of a long bone because osteons runs parallel to the long axis of the bone and it is a structural unit of cortical bone which contain lamillae, a bone layer that surrond the hollow passageway called Harvesian canal and this canal contain blood vessels that supply blood to osteocytes.
