Answer:
Arteries-1.Involved in carrying pure, oxygenated blood and nutrient-rich blood.
2.Consists of three distinct layers, which are rigid, thicker and highly muscular.
3.Located deep within the body.
4.Red in colour.
5.Carry blood away from the heart to various parts of the body.
6.High pressure, as the blood flows by the pumping pressure of the heart.
7.Comparatively higher oxygen level.
8.The level of carbon dioxide is low
9.Lumina is narrow
10.Valves are absent
11.Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.
Veins-1.Involved in carrying impure, deoxygenated blood
2.Consists of three distinct layers, which are thin and collapsible.
3.Peripherally located closer to the skin.
4.Blue in colour.
5.Carry blood towards the heart from the various parts of the body.
6.Low pressure, as the blood flows by the capillary action of the veins.
7.Comparatively low oxygen level.
8.The level of carbon dioxide is high
9.In upward direction from the body tissues to the heart.
10.Lumina is wide & Valves are present.
11.Veins are less susceptible to diseases such as varicose veins.
Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.
As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure
During glycolysis, what is the source of the chemical energy that is captured in ATP?
A. the chemical bonds in pyruvic acid
B. the chemical bonds in glucose
C. the nuclei of atoms in glucose
D. high-energy electrons in the cytoplasm
The study of the cell is called cell biology.
The correct answer to the question is option B which is the chemical bonds in glucose.
What is glycolysis?The breakdown of glucose into pyruvic acid is called glycolysis.
According to the question, the source of the ATP is by breaking down the glucose molecule and forming the ATP by gaining the extra phosphate molecule.

How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.
