Answer:
Lack of food sources, the lack of habitat, competition and evolving ways to compete.
Explanation:
Lack of food sources, the lack of habitat, competition and evolving ways to compete are the ecological conditions that is responsible for the rapid diversity of some lineages. With the passage of time, changes occurs in the lineages due to climate change which causes some species to extinct and some to evolve which attains adaptability to the environment. Due to climate change food is unavailable to the organisms which is the main cause of its extinction.
Answer:
Both the smooth and rough endoplasmic reticulum help in the production and storage of proteins The main difference is that one contains ribosomes on it and the other does not. The rough endoplasmic reticulum (RER) has ribosomes on its surface. This is what give the rough endoplasmic reticulum a "rough" appearance.
Explanation:
To make two daughter cells, the contents of the nucleus and the cytoplasm must be divided. The mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell, and then the cell is divided into two new identical daughter cells. The first portion of the mitotic phase, mitosis, is composed of five stages, which accomplish nuclear division. The second portion of the mitotic phase, called cytokinesis, is the physical separation of the cytoplasmic components into two daughter cells.
renewable products are better because we do not have to kill plants for mass products and it is harmful if trashed in a habitat because it can poison waters kill wildlife that drink from it swim from it
Answer:
The correct answer is: c) the heart rate slowed and eventually stopped.
Explanation:
The vagus nerve (X) is a cranial nerve with the function to parasympathetically <u>innervate the heart, the lungs and the digestive tract. </u>
As a part of the Autonomic Nervous System (ANS), the vagus nerve regulates things such as heart rate and gastrointestinal peristalsis (things we cannot control).
Given that it is a component of the parasympathetic division of the ANS, it stimulates the organs when the individual is performing normal activities like <u>resting and feeding</u> (unlike the sympathetic division, responsible for the fight-or-flight response). For this specific reason, the vagus nerve slows the heart rate, so if it were to be stimulated in a frog, it would produce the same thing and ultimately lead to its heart stopping.
