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>
Answer:
"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.
"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.
These statements are true, however:
SUNLIGHT
CARBON DIOXIDE
WATER
MINERALS
OXYGEN
PLANT SUGARS
Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.
Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).
Answer: Blood contains numerous biconcave cells called erythrocyte , contained in a featureless matrix called plasma
Explanation:
Blood is a liquid contain in the body of man and animals that transport the necessary nutrients and oxygen to the cell and then takes away metabolic waste from the cell. There are numerous cells in the body which are the Red blood cells and also the red blood cell.
This red blood cell is also called erythrocyte which is the numerous biconcave cells. This white blood cells and erythrocytes are all in the blood plasma. Both the erythrocytes (i.e red blood cell) and the white blood cell are all contained in a featureless matrix called the plasma.
This plasma is made up of blood, water, carbon dioxide, dissolved proteins, and hormones.
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula.
