<span>Transmitted via neurotransmitters. There is a gap between two neurons. This place where the axon meets with dendrite is callde synapse. Neurotransmitters which are chemicals help transmit the signals from axon to dentrite. Calcium ions play major role in this process.</span>

List the order the steps of the path of blood through the kidneys.
Alexxandr [17]

Blood flows to the kidneys through the right and left renal arteries. Inside each kidney these branch into smaller arterioles.

The blood is at very high pressure and flows through the arterioles into tiny knot of vessels called the Glomerulus. These are located in the nephrons.

From the glomerulus the blood pressure drops and the blood flows into arterioles which coil around the nephrons. These in turn connect to a series of small veins. These vessels reunite and ultimately form the renal vein.

About one quarter of the total cardiac output (or total blood flow) circulates through the kidneys. This equates to just over 1 litre of blood every minute.

Hope this helps (:

What does measles cause by​
omeli [17]

Answer:Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing. If other people breathe the contaminated air or touch the infected surface, then touch their eyes, noses, or mouths, they can become infected.Measles is caused by a virus in the paramyxovirus family and it is normally passed through direct contact and through the air. The virus infects the respiratory tract, then spreads throughout the body. Measles is a human disease and is not known to occur in animals.

It usually begins as flat red spots that appear on the face at the hairline and spread downward to the neck, trunk, arms, legs, and feet. Small raised bumps may also appear on top of the flat red spots. The spots may become joined together as they spread from the head to the rest of the body.

slava [35]

Seeds perform various functions for the plants that generate them, among them the essential function is dispersal to a new location, nourishment of the embryo, and dormancy at the time of inappropriate conditions.  

Seed coat is the part of the seed that protects the seed from temperature-associated, physical, or water destruction, it helps in the protection of developing embryo, and it is the seed coat, which makes sure that the plant seed remains in a dormant state until the circumstances become ideal for the plant embryo to sprout or germinate.

Suppose a new mutation that improves metabolic efficiency is lost from a small population of mammals living in a region of seaso
Troyanec [42]

Answer:

C) genetic drift.

Explanation:

Genetic drift is the random change in the frequency of alleles in a population due to random sampling. Many circumstances can lead to genetic drift for example bottleneck effect, founder effect, etc.

The bottleneck effect occurs when most of the members of a population die because of any natural disaster like flood, fire, etc. This can cause a certain allele to be lost in the remaining population because of losing major populations. So here due to hurricane half of the mammal population gets eliminated which shows it is an example of the genetic drift.
