Answer:
A) The scientific study of the distribution and abundance of organisms and their interactions with the environment.
Explanation:
Ecology is the part of biology that is concerned with the study of the relationships established between living beings and theirs with the environment in which they live. It is a term derived from the Greek that was formed from the junctions of the words "oikos" and "logos", which mean, respectively, home and study. Thus, the term Ecology refers to the study of the “home” of every organism on the planet.
The term Ecology was first used in 1866 by a German zoologist named Ernst Haeckel, in a work called "Generelle Morphologie der Organismen". In this work, the author defined Ecology as "the scientific study of the interactions between organisms and their environment."
The main events of telophase include a reappearance and enlargement of the nucleolus, enlargement of the daughter nuclei to their interphase size, decondensation of the chromatin resulting in a brighter appearance of the nuclei with phase-contrast optics, and a period of rapid.
Answer: C
Explanation: Cells reproduce and divide through a process called mitosis
The correct answer is that ammonia is removed from the blood by the liver, which processes it into urea, and discharging it into the circulation.
The liver plays an essential function in the metabolism of proteins. The cells in the liver modify amino acids in foods so that they can be utilized to generate energy, or make fats or carbohydrates.
A toxic component known as ammonia is a waste-product of this procedure. The liver cell transform ammonia to a much less toxic component known a urea, which is discharged into the blood. Urea is then translocated to the kidneys and is removed out of the body in the form of urine.
