As the intense competition of the species are observed in clumped distribution, so the answer is distribution of individuals will tend to be clumped.

<h3>What is intraspecies competition?</h3>

The competition which  occurs between individuals of the same species  based on common need for a limited resources,  leading to a reduction in the survival and reproduction rate.

One of the original Amish colonies rose from a ship of colonists that came from Europe. The ship’s captain, who had polydactyl
ANTONII [103]

Answer:

B and C

Explanation:

When the Amish came to their new home, they were founding a new colony. This is considered a founding effect.

Now, there is another thing to keep in mind, and that is that the Amish are very strict about their custom, for example, the idea of family and identity. This led them to form couples, only among the members who belonged to the community.

As generations go by, genealogical relationships between individuals in the population become closer. This causes some genes, by mere probability, to become fixed (i.e. they are the only ones left in the population). As a consequence of this, the frequency of rare genes increases (polydactyly). This evolutionary process is known as gene drift.

Describe the effects of NE and Ach on contractile force that you observed today. Given your knowledge of sympathetic and parasym
Afina-wow [57]

Answer:

The answer is Norepinephrine.

Explanation:

Acetylcholine (Ach) and Norepinephrine (NE) are both chemical substances (neurotransmitters) released primarily by nerve cells and they affect different parts and systems of the body. Acetylcholine mostly targets the muscles and the brain and it is a part of the parasymphatetic nervous system whereas norepinephrine targets the whole body and has an effect that leads to the contraction of muscles and the increase of the heart rate. Norepinephrine is a part of the symphatetic nervous system.

Since the symphatetic nervous system is responsible for the crucial "fight-or-flight" response of our body, it has a more dramatic effect on the muscle contraction. Norepinephrine, being a part of the symphatetic nervous system, should result in a more drastic change in contractile force.

I hope this answer helps.
