Answer:
The organismal theory
Explanation:
Because the organismal is the scientific study behind how our bodies work =) hope this helped
The answer is B. artificial selection. Artificial selection is . a process in the breeding of animals and in the cultivation of plants by which the breeder chooses to perpetuate only forms that have certain desirable inheritable characteristics (such as, in this case, cows that produce the most milk).
To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
The control of blood glucose is mainly made by a negative feedback loop linked with the hormones insulin and glucagon, where the insulin is in charge of effectively lowering the blood glucose levels. We can divide the process of control of the blood glucose homeostasis in some events, being those events:
1 - The stimuli - when the body receives sugars from the food the glucose levels in the blood rises;
2 - Beta cells - the stimuli is receive by the control center of the levels of blood glucose (pancreas), and the Beta cells of the pancreas releases insulin into the blood;
3 - Insulin function - the insulin takes the glucose that is free in the blood to the liver (takes up glucose and stores it as glucagon) and to body cells, making the blood levels of glucose to decline;
Homeostasis = blood glucose 90mg/mL.
4 - The stimuli - when blood glucose level falls, after some time before meals and physical activities;
5 - Alpha cells - the stimuli is receive by the control center of the levels of blood glucose (pancreas), and the Alpha cells of the pancreas releases glucagon;
6 - Glucagon function - the glucagon released by the pancreas goes to the liver and promote the break of glycogen molecules, it causes the release of glucose into the blood, since glycogen is a reserve of glucose of animals, the blood glucose level rises;
Homeostasis = blood glucose 90mg/mL.
Answer:
Since sister chromatids are identical, genetic variation will not be produced in the daughter cells.
Explanation:
Sister Chromatid Exchange (SCE):
- This is a rare recombination phenomena that entails recombination and crossing over between two sister chromatids.
- This is contrary to normal recombination in which crossing over between non-sister chromatids takes place, producing genetically variable daughter cells.
- Exchange of genes between sister chromatids does not produce genetic variations.
- SCE is actually an indicator of chromosomal instability and DNA repair and replication malfunction.
- SCE is observed to be increased in pathological conditions like Bloom syndrome (genetic disorder) and Behcet disease (chronic inflammatory disorder) etc.
