I cannot see the imagine very well would you mind taking another?
The molecule that is the primary source of energy in all cells is ATP, which is definitely not a macromolecule. Other primary sources of energy include other sugars, proteins, and fats. Hope this answers the question. Have a nice day.
Answer:
When organisms use organic matter for cellular respiration, ALL the matter goes back into carbon dioxide, water, and minerals, while ALL the energy leaves the ecosystem as heat (which is ultimately radiated out into space). So matter cycles, energy flows through ecosystems.
Answer:
The proper answer is D.
Explanation:
When fertilization occurs, the corpus luteum continuously secrets female hormones and allows implantation. However, if the egg is not fertilized, the corpus luteum starts to degenerate, and the secretion of female hormones stops.
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) <u>Diffusion</u>: it is a passive trans-membrane transport mechanism.
b) <u>Mitosis</u>: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) <u>Photosynthesis</u>: is the mechanism by which plants obtain energy and nutrients, from solar energy.
