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.
Answer:The answer is spinal cord
Explanation:
The central nervous system consists of the brain and the spinal cord.
The brain is the most highly specialized organ, and is protected by the skull or cranium, while the spinal cord is made up of soft tissue which runs from the medulla oblongata to the tail region. It is protected by the bones of the vertebral column.
The spinal cord acts as a PATHWAY between spinal nerves and the brain.
Having broken down walls of Glomerulus would cause blood to appear in urine because instead of only filtrate passing into the capsule, the blood would also flow into the capsule and be released with the urine.
Answer:
The mecanism is termed as feedback inhibition.
Explanation:
In an enzyme catalyzed sequential reaction the end product of that reaction inhibits the activity of the activity of the enzyme catalyzing the ist step This type of regulation is called Feed back regulation or feedback inhibition.
The main function of human body is to maintain the homeostasis of the all the components it contains.When the end product of an ongoing enzyme catalzsed sequential reaction is produced in a high lebel at that time to maintain its own homeostatis that end product inhibits the functioning of the enzyme catalzsing the ist step of that biochemical reaction.
For Example Cytidine tri phosphate inhibits the activity of aspartate transcarbamoylase catalyzing the de novo biosynthesis pathway of pyrimidine metabolism.
Explanation:
Nondisjunction: Failure of paired chromosomes to separate (to disjoin) during cell division, so that both chromosomes go to one daughter cell and none go to the other. Nondisjunction causes errors in chromosome number, such as trisomy 21 (Down syndrome) and monosomy X (Turner syndrome). It is also a common cause of early spontaneous abortions
