Answer:
D.) pleiotropy
Explanation: Just took the quiz.
Pleiotropy arises when one gene affects two or more seemingly unrelated phenotypes. A pleiotropic gene expresses many phenotypes. Therefore, option (D) is correct.
What is Pleiotropy?
When one gene influences two or more phenotypic qualities that do not appear to be related to one another, this phenomenon is known as pleiotropy. A gene is said to be pleiotropic if it can exhibit many phenotypic expressions in a single organism.
Phenylketonuria is a condition that serves as a straightforward illustration of a pleiotropy. A slow metabolism of the amino acid phenylalanine in the cells of the body is the root cause of this hereditary condition, which causes phenylketonuria.

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.

Answer:
By using genetic engineering to insert the gene for the desired enzyme into the bacterial chromosome, then growing large amounts of the modified bacteria in fermenters.
Explanation:
Answer:
Bacteria such as fungi or algae are inserted in fermenter and feedstock such as glucose, amino acid, sucrose are inserted to be a source of food for them.
Then they are left for a time for the bacteria to reproduce more and to produce more enzymes in their cells, Then if the enzymes are extracellular they are extracted directly from the filtrate, if they are intercellular they are separated from the feedstock and crushed to be separated with any solvent such as water.

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 of these options is not a mechanism to control the opening and closing of ion
channels?
a) ATP binding (ATP gated)
b) Ligand binding (ligand gated)
c) Changes in membrane potential (voltage gated)
d) Distortion of the cell membrane (mechanically gated)
Answer:
D) ATP binding (ATP gated)Explanation:
There are three types of ion gated channel regulated by ligand binding, change in membrane potential and distortion of the cell membrane...
So the answer is ATP Binding( ATP gated) is not a mechanism to control opening and closing of Ion channels.
ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).
ATP-gated channels are membrane channel proteins that open in response to binding ATP.
These channels require energy in the form of ATP to open and thus allow the passage of ions/molecules across biological membranes.
For example, the P2X7 receptor is an ATP-gated channel that mediates apoptosis (programmed cell death) of immune cells.
In conclusion, ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

which molecules determine the tissue specificity of hormones?
Answer:
Steroids. Which molecules determine the tissue specificity of hormones? Receptors. Hormones bind to receptors on target cells and trigger a cellular response.
Explanation:
The tissue specificity of hormones is determined by hormone receptors. Proteins called hormone receptors are found on the cell surface. A hormone's binding to its receptor starts a chain of actions that eventually affects the activity of the cell.
For various hormones, different cells have various receptors. This implies that a hormone can only attach to cells that also contain such receptors. The tissue specificity of hormones is a result of this.
For instance, the insulin hormone attaches to receptors on cells in the muscle, fat, and liver tissues. These receptors bind to insulin, which sets off a series of processes that eventually result in the absorption of glucose from the circulation by these cells.

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)
