Ans. Option (IV).
Mosses can be defined as non-vascular, flowerless plants that are found in shady or damp regions and reproduce via haploid spores. During reproduction in moss, haploid male gametes or spores are released into surrounding environment that fuse with female spores to form zygote that develop into mature sporophyte.
Angiosperms are vascular, flowering plants that reproduce by seeds. During reproduction in angiosperms, haploid male gametes or pollen grains are released into surrounding environment that fuse with female gametes or eggs to form zygote that develop into seed.
Thus, the correct answer is option (IV).
Answer:
The correct answer is option C. "disruptive selection".
Explanation:
Disruptive selection is a type of natural selection at which extreme values for a trait are favored, while intermediate traits are more likely to disappear. In this example the finches tended to have either small beaks or large beaks because small beaks are best at eating soft seeds and large beaks are best at cracking seeds. This is an example of disruptive selection because the two extreme values for the size of beaks are favored.

Answer:
Hello!
The answer is D) Homeostasis
Explanation:
Homeostasis:
<em>The regulation of a cell or an animal's internal environment in response to fluctuations in the external environment is called homeostasis. </em>
Homeostasis is crucial to maintain an optimum environment for cell structures to work effectively.
In this case, the jackrabbiit's circulatory system is responding to fluctuating temperatures. In hot days, the body is at risk of heating up above optimum temperature which could hamper body functions. Therefore, the blood flow to the ears is increased to facilitate heat loss.
In cold temperatures, the blood flow to the ears is decreased to conserve heat for vital body organs. The blood flow is directed to the core of the body to protect the heart, lungs, liver and brain.
