The answer is skin. The skin is also the largest organ in the body and has the most contact with the outside environment. It is estimated that there are approximately 205 identified genera of bacteria alone on the skin. This normal flora of the skin play significant roles in the body such as augmenting immunity.
Answer:
The conclusion that cuckolder are able to discriminate kin from non kin
Explanation:
From the above question, researchers carried out tests on the two types of fish (males cuckolder and parental males) to see if they can identify kin and non kin from the offsprings, using a null test.
But the test for cuckolder was rejected by the researchers for the cuckolder so they can't say cuckolder can indentify between kins and non kins, they didn't pass the test so it should be concluded that cuckolder can't identify between kin and non kin, instead of concluding they can identify them, that is the wrong conclusion.
Answer: A. Carbon dioxide is a product.
Explanation: During cellular respiration the body takes in oxygen and uses it and turns it into carbon dioxide and lets it out, thus carbon dioxide is a product.
Answer:
<u>Active transport across membranes is like refilling an empty soda can after pouring the soda into a cup. It takes effort (energy in the form of ATP) to pour the soda back into the can, it wouldn't typically happen on its own.</u>
Explanation:
Cells use several transport mechanisms to move substances across their plasma membranes. Plasma membranes control all movement of substances through passive transport, which does not use energy; and active transport which requires chemical energy in the form of ATP.
Active transport moves substances out of cells against their gradients. In the cell, glucose can be transported inwards for respiration. However, because the internal environment is typically concentrated, (and glucose is needed in high amounts) this requires the use of transport enzymes and ATP.
