Explanation:
drag each label into the appropriate category to designate whether the given item describes elements of gray or white matter of the spinal cord.
In regards to the composition of the spinal cord, the grey matter is the centermost substance, whilst white matter is located towards the peripherals.
Though I could not locate the labels and categories online in order to properly classify each one, I can provide a general overview of the subject to aid in your understanding and ability to complete the project.
The spinal cord acts as a path through which billions of signals from the brain travel to reach the rest of the body. This pathway is occupied by grey and white matter, which are the representation of the billions of neurons that make up the central nervous system.
Grey matter is located towards the center of the spinal cord and is often described to be in the shape of a butterfly. Grey matter is the accumulation of nerve cell bodies and unmyelinated axons. In contrast, white matter makes up the surrounding area to that of grey matter and corresponds to the myelinated axons of various nerve cells. The white coloration of the white matter is due to the myelin itself.

8. Explain why mammals have specialized excretary organs but plants do not have.
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
They consume food and they have much higher metabolism. That means that more waste products are produced. Plants can use much of the waste produced and it is in fact raw material. Animals don't normally produce their own chemicals from scratch like plants normally do so they can't just recycle the waste. They need to remove it. About the only waste plants need to get rid of is excess oxygen produced during the day. That is actually three reasons but recycling is related to plants not consuming but making their own chemicals from scratch. In a way it pretty much comes down to one main reason.

How are the amounts of carbon dioxide and oxygen inhaled by lungs different from the amounts exhaled? How do cellular respiration and the law of conservation of mass relate to this?
I NEED HELP!!
Answer:
1. Gas exchange takes place by diffusion in the alveoli within the lungs. As a result the composition of inhaled and exhaled air is different.
...
Inhaled and exhaled air.
Gas % in inhaled air % in exhaled air
Oxygen 21 16
Carbon dioxide 0.04 4
Nitrogen 79 79
NB These figures are approximate.
2. The amount of carbon-dioxide atoms released by respiration are exactly equal to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.
Explanation:
What is Cellular Respiration?
Cellular Respiration is the process in which the cells of living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. The overall chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP)
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals.
Q: How is cellular respiration related to breathing?
A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation.
Energy Changes in Cellular Respiration
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Some of this energy is converted to heat. The rest of the energy is used to form many small molecules of a compound called adenosine triphosphate, or ATP. ATP molecules contain just the right amount of stored chemical energy to power biochemical reactions inside cells.

Which example(s) of cell transport do/does not require chemical energy?
A.
Drops of blue food coloring are placed in water and spread throughout the water, turning it blue.
B.
A potato slice is placed in water and water molecules from inside the potato move into the surrounding water.
C.
both A and B
D.
neither A nor B
Answer:
C
Explanation:
Because osmosis(B) this is where water moves from a high concentration to a low concentration across a partially permiable membrane( No energy required). Whereas in diffusion (a) this is the net movement of particles from a region of a high concentration to a region of a low concentration. This stops when the region is evenly spread. (No energy is required)
The cell transport which takes place in food coloring, potato slice is concentration gradient. This type of cell transport does not need energy. Thus, the correct option is C.
What is Cell transport?
Cell transport is the transport of molecules through the cell membrane. Transport of substances through the membrane takes place through osmosis and diffusion.
The diffusion of substances can be active or passive on the basis of requirement of energy. The passive mode of transport does not require energy as the movement of substances occurs down the concentration gradient from high concentration to low concentration. Whereas, in active transport energy is required in the form of ATP as the transport occurs against the concentration gradient from low concentration to high concentration.
Therefore, the correct option is C.

Answer:
" Natural gas does not produce greenhouse gases as other energy sources do."
Explanation:
The answer, "Coal deposits are found on nearly every continent and mining coal poses few risks." shows only how it can be a better option, but does not show how it can benefit.
The answer, "Petroleum is relatively inexpensive compared to other forms of energy." only shows how it can be a better option, but does not show how it can benefit.
The answer, "Nuclear power increases water vapor in the atmosphere." does not clearly state how this benefits us.
-kiniwih426
Answer:
Petroleum is relatively inexpensive compared to other forms of energy.
Explanation:
Because:
"Natural gas does not produce greenhouse gases as other energy sources do." natural gas does produce greenhouse gases, including carbon dioxide and water vapor, the natural gas mostly releases the greenhouse gas.
"Coal deposits are found on nearly every continent and mining coal poses few risks." coal is inexpensive, but could be damaging to the habitats around the coal mining.
"Nuclear power increases water vapor in the atmosphere." nuclear powder doesn't really increase water vapor, but makes water vapor.
"Petroleum is relatively inexpensive compared to other forms of energy." it is inexpensive if compared to other fossil fuels. (aka, the most inexpensive)

Answer:
Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts. Bones also contain blood vessels, nerves, proteins, vitamins, and minerals. Also called osseous tissue.
A quick anatomy of the bone! (extras)
Anatomy of the bone. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.

he valve presents at the mouth of the pulmonary artery
Explanation:
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves, the other being the aortic valve. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.
