Answer:

Huntington's disease is an autosomal dominant disorder, which means that a person needs only one copy of the defective gene to develop the disorder. With the exception of genes on the sex chromosomes, a person inherits two copies of every gene — one copy from each parent.

Answer:

The stratosphere

contains the ozone layer ,

is used by airplanes,

has strong, steady winds , and

increases in temperature as altitude increases .

Explanation:

The stratosphere is the atmospheric layer between 10 km and 50 km above the Earth's surface.

It includes the ozone layer, which is at an altitude of about 20 km.

It has strong, steady winds that can reach as high as 220 km/h.

Passenger aircraft generally fly in the lower levels of the stratosphere, at altitudes of about 10 km to 12 km.

Temperatures increase with altitude, from -50 °C at 10 km to -3 °C at 50 km.

A is wrong. The mesosphere (altitude 50 km to 85 km) is the coldest of the atmospheric layers, with temperatures as low as -90 °C at 85 km.

The division of the autonomic nervous system that is short‐lived and very localized is.
Kipish [7]

The division of the autonomic nervous that is short-lived and very localized is parasympathetic system.

What is nervous system?
The nervous system includes the brain, spinal cord, and a complex network of nerves. This system sends messages back and forth between the brain and the body. The brain is what controls all the body's functions. The spinal cord runs from the brain down through the back. The parasympathetic nervous system predominates in quiet “rest and digest” conditions while the sympathetic nervous system drives the “fight or flight” response in stressful situations.

The main purpose of the PNS is to conserve energy to be used later and to regulate bodily functions like digestion and urination.

anygoal [31]

ANSWER:  B, killifish

REASONING: A secondary consumer consumes animals that eat only plants.  Larvae and copepods do not fit these descriptions, because they do not eat animals.  Snapper do eat animals, so do not fit the description either.  Killifish eat small animals that do eat plants.
