Answer:
-Sensors in the brain detect a lack of oxygen.
-The muscles in his body need more energy and therefore more oxygen.
Explanation:
-Sensors in the brain detect a lack of oxygen.
-The muscles in his body need more energy and therefore more oxygen.
-The body has too little carbon dioxide to maintain function.
-The body is using carbon dioxide instead of oxygen to make energy.
-Blood pressure has decreased, so less blood is being pumped to the muscles.
<em>The correct answer would be that </em><em>sensors in the brain detect a lack of oxygen</em><em> and t</em><em>he muscles in the body of Jon need more energy and therefore, more oxygen.</em>
At sea level, the atmospheric pressure easily allow oxygen to permeate the cells of the lung and diffuse into the blood. At high altitudes, air pressure is generally lower and permeation/diffusion through the cells of the lung into the blood becomes difficult.
<u>Without adequate oxygen, the body cannot generate energy needed for physical activities of muscles. Consequently, the sensors in the brain detect a lack of oxygen and the body system reacts by breathing heavily to compensate for the oxygen shortage.</u>
Listed under are the 5 different type of cells found in the epidermis and their description:
1. Stem cells
These are what you call undifferentiated cells. These are cells found in the stratum basale, which is the deapest layer of the epidermis. These cells divide to create keratinocytes.
2. Keratinocytes
The make up the majority of the cells in the epidermis. They synthesize keratin which are proteins that make up your hair, skin, and nails. They can also be found in other organs inside your body.
3. Melanocytes
These cells can only be found in the stratum basale. They synthesize melanin with a brown to black pigment. These dark pigments serves as protection for the skin from harmful UV rays.
4.Merkel cells
Merkel cells are also known as <em>tactile cells</em>. They are the sensory receptor for touch. Merkel cells and the nerve fiber together are called the Merkel disc.
5. Dentritic cells
They are also known as <em>Langerhans cells</em>. They can be found in two layers of the epidermis: the stratum spinosm; and stratum granulosm. They are what you call macrophages that come from the bone marrow. They serve as immune cells that provide protection against toxins, microbes and other pathogens that try to penetrate the skin.

answer is C spermatogenesis
Answer:
There is a 50% chance their child will have blue eyes.
Answer: CHANNEL PROTEINS provide openings in the plasma membrane for substances to flow through without changing structure, and CARRIER PROTEINS allow passage of substances through the plasma membrane after undergoing a subtle change in shape.
Explanation: They are described thus:
A channel protein is a protein that allows the transport of specific substances across a cell membrane.
Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell’s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.
