Answer:
I would say the answer would be: 2. The heart contracts and expands to move blood.
Explanation:
The heart is forcing itself to contract and expand so it can move blood throughout the body. If I am wrong, let me know, but I believe that this is correct since it's a function of force.
Answer:
Explanation:
Both parents have black color and normal vision but some of their progenies show brown color and some shows PRA, this reveals the brown coat color and PRA are recessive traits and both parents are heterozygous. The progenies include black normal vision, brown normal vision and black, PRA, that is the alleles for these genes separate independently of each other.
Let us denote the alleles as B-black, b-brown and P-normal vision, p-PRA, then the genotype of the heterozygous parent is BbPp, alleles separate independently of each other so the possible gametes are alleles for the color and vision segregate independently during gamete formation.
Thus, option C is correct.
Answer:
a) and d)
Explanation:
An homeostatic process is the process that allows the body to <u>reach and maintain an state of equilibrium</u>, this process allows the body to self-regulate itself and therefore when it detects that some parameters are out of range, it works to get those parameters back to where they are supposed to be.
Therefore, the definition of a homeostatic process contains two basic statements:
a) The maintenance of certain body variables within a fixed range.
d) The process that reduces the deviations from the set point.
It IS NOT A because after a fire, soil remains, so it would be secondary, not primary. D is INCORRECT because after a volcano, only rock is left so it is primary succession, not secondary.
If you can post the picture I could tell you the correct answer.
