They are a good choice because at any given time, you can find cells that are undergoing mitosis.
1.The presence of valves 2.the milking action of skeletal muscles 3. the veins as the muscles contract
1) Both involve electron transport chains.
<span>2) Chemiomosis allows ATP synthase to produce ATP. </span>
<span>3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) </span>
<span>4) Both utilize ATP for energy at some points. </span>
<span>5) Both provide power for cellular activities. </span>
<span>5 Differences </span>
<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
<span>4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) </span>
<span>5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).</span>
Answer:
The GIT mucus lining of the GIT serve as a physical barrier to the movement of digested food substances.
The mucus also help to prevent inflammation of the bowels; by reducing or suppressing immune response to inflammation.
In Cystic fibrosis, the blockage of the ducts by the mucus, prevents enzymes from reaching the digestive food substances,. The resulting undigested food substances leads to bloating, pain, cramps, gas, smelly belch, constipation, and smelly stools.
Explanation:
Answer: It is no longer circulated throughout the body supplying oxygenated blood. The un-oxygenated blood turns blue which makes the body look “dusky”. Since it is no longer circulating, the blood pools in the lowest part of the body making these areas looked dark or bruised. (If the person was laying on their back, the blood would pool on the backside of the body)
Explanation:
When a person dies, the heart stops circulating blood and the lungs stop oxygenating the recirculated blood. The blood turns blue and pools in lowest place.
