Explanation:
A plant that utilizes the Crassulacean acid metabolism (CAM) as an adaptation for arid conditions. CO2 entering the stomata during the night is converted into organic acids, which release CO2 for the Calvin Cycle during the day, when the stomata are closed.
Answer:
False
Explanation:
When we breathe, our lungs give us carbon dioxide (which is poisonous for humans) to take in O2
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).
The fusing together of two gametes at fertilization is sexual reproduction
why you may ask???
explanation to why- why you ask because think about it no matter what sub-stents your talking about as long as its living it is able to give birth unless uncapible and if the eggs to an gametes is fertilized and the sperm hits the egg in order for it to hit the egg they would have to have had sexual contact to make it hit the egg and then counting it as sexual reproduction know in another case if it does not hit the egg it is asexual or if you didn't have sexual contact it would be asexual meaning not sexual but in the question you asked yes it would be unless a problem accrued :P
Hope i could help :)<span />
