In cells with a nucleus, as in eukaryotes, the cell cycle is also divided into three periods: interphase, the mitotic (M) phase, and cytokinesis. During interphase, the cell grows, accumulating nutrients needed for mitosis, preparing it for cell division and duplicating its DNA.
Answer: The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.
Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.
The Objective of the experiment, the hypothesis, the variables Like Independent Variable, Dependent, Variable, Controlled Variable
Answer:
The receptors in the aortic and carotid bodies are chemoreceptors.
Explanation:
Chemoreceptors are specialized cells that are responsible for detecting and converting chemical signals into biological signals, to relay that information to the brain, where they will finally be interpreted. Among them we find the peripheral chemoreceptors, which are the aortic bodies, located along the wall of the aortic arch and innervated by the vagus nerve, and the carotid bodies, located in the neck. . Carotid bodies are stimulated by variations in the concentration of oxygen and carbon dioxide in the blood, as well as variations in blood pH. When the pH decreases the CO2 increases and the oxygen decreases, they activate the chemoreceptors to increase breathing.

Answer:
India was a separate continent until 45 million years ago
Explanation:
India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.
