They evolved during the Cambrian explosion.
I guess that is:
Within the capillaries of the lungs, gases are exchanged by diffusion; O2 diffuses from the alveolus to the bloodstream and CO2 diffuses from the bloodstream to the alveolus.
Answer:
The thermometer can not be used to measure very low temperature
Explanation:
Mercury-in-glass thermometer is one of the types of liquid-in-glass thermometers.
Given the very melting point of mercury, it is unsuitable to attempt to use this thermometer for very low temperature measurement.
Hence, from the melting point of mercury, this thermometer can not be used to measure very low temperature.
Answer:
hmmmm MARK ME BRAINLIST
Explanation I think Characteristics of ATP. Adenosine triphosphate (ATP) is an essential aspect to life, as it is the basic source of energy for all known living cells. ATP serves a dual function: it is individually a source of energy, as well as being involved in processes that release more energy when it is broken down to form adenosine diphosphate (ADP).
Answer:
Sexual reproduction:
Pros: leads to greater genetic variation.
Cons: requires more time and energy.
Asexual reproduction:
Pros: Does not require finding a mate.
Cons: Produce less genetic variation.
Explanation:
Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals.
Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis.
Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development.
Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion.
Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate.
Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.
