Answer:
Motor neurons
Explanation:
Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements. There are in fact two types of motor neurons: those that travel from spinal cord to muscle are called lower motor neurons, whereas those that travel between the brain and spinal cord are called upper motor neurons.
Motor neurons have the most common type of ‘body plan’ for a nerve cell - they are multipolar, each with one axon and several dendrites.

Hypothesize how photosynthesis can affect these changes, explain in 3 to 5 sentences
The process of the formation of food by trapping the sunlight with the help of chloroplast is called photosynthesis.
These are the following which are used in process photosynthesis:-
-Carbon dioxide
-Water
-Sunlight
Photosynthesis is greatly dependent on the amount of carbon dioxide concentration in the atmosphere because photosynthesis is the process where carbon dioxide gas is used in large amounts.
If the vegetation occurs higher in the season, the decrease will occur in the carbon dioxide concentration of the atmosphere while on the other hand, if less vegetation occurs then there is a higher amount of carbon dioxide concentration in the atmosphere.
Hence, the larger the amount of carbon dioxide more the yield from photosynthesis. In some cases, the high amount of carbon dioxide also acts as a poison.
Large multicellular organisms are made of a variety of cell types. Do all of the types of cells pass through the cell cycle at the same rate?.
Answer: it depends on what type of cells they are. Some types of cells divide rapidly, and in these cases, the daughter cells may immediately undergo another round of cell division.Other types of cells divide slowly or not at all
Explanation:
explain how radioactive isotopes can be used to determine that the oxygen produced during photosynthesis comes from the hydrolysis of water
One radioactive isotope of oxygen, O18, is utilized as a reactant, and the products generated in the reaction are investigated.
How can we be certain that the oxygen produced during photosynthesis is derived from water?To track the destiny of oxygen atoms during photosynthesis, a heavy isotope is used as a tracer. The investigations demonstrated that only when water was the source of the tracer did the O2 from plants get labeled with 18O.
Who established that the water that water evolved from during photosynthesis is oxygen?Ruben and Kamen are the right response. Ruben and Kamen established that water is the source from which oxygen developed during photosynthesis. The splitting of water molecules to release oxygen molecules is referred to as photolysis, which is an oxidation of water.

at the time of ovulation during the menstrual cycle, the corpus luteum degenerates into scar tissue and stops making progesterone and estradiol. true false
Every time you ovulate, a menstrual cycle fresh corpus luteum develops, and when you no longer require it to produce progesterone, it disintegrates.
What transpires during the menstrual cycle's corpus luteum stage?Luteinizing phase
The corpus luteum, which is made up of ovarian cells, releases progesterone and a tiny amount of estrogen after ovulation. As a result, the uterine lining thickens in preparation for pregnancy.
After ovulation, does the corpus luteum deteriorate?If the oocyte is not fertilized, the corpus luteum stops secreting hormones within 14 days following ovulation, and the resulting corpus albicans scar develops inside the ovary.

Water will migrate into an animal cell in a hypotonic solution (high osmotic pressure), causing the cell to enlarge and possibly explode.
What occurs when an animal cell is inserted into a solution where there is more water outside the cell than inside?
The solution is hypertonic because the concentration of dissolved chemicals in the solvent is higher than that inside the cell. As a result, the cell will shrink and water will leak out.

What are the common types of mutations that occur to convert proto-oncogenes to oncogenes?.
The most frequent mutations that can change proto-oncogenes into oncogenes include insertion mutations, chromosomal rearrangements, point mutations, amplification, and gene fusion.
Insertion mutations:
Insertion mutations occur when an extra nucleotide is inserted into a gene sequence. This type of mutation can cause a shift in the reading frame of the gene, resulting in the production of proteins with altered functions. In the case of proto-oncogenes, an insertion mutation can result in the protein being highly active, leading to unregulated cell growth and the formation of a tumor.
Chromosomal rearrangements:
When two genes are relocated to various positions on a chromosome, chromosomal rearrangements can happen. As a result, the two genes may express themselves simultaneously, which may transform a proto-oncogene into an oncogene.
Point mutations:
Point mutations are minute adjustments to the DNA's structure that can turn a gene into an oncogene. These mutations change the DNA sequence by adding, deleting, or substituting a single nucleotide.
Amplification:
Amplification is the process by which the number of copies of a gene increases. A proto-oncogene may develop into an oncogene as a result of this increasing the gene's expression.
Gene fusion:
Combining two distinct genes can result in the synthesis of an aberrant protein.

which ions move into the synaptic bulb in order to move the vesicles containing neurotransmitter to the presynaptic membrane?
Calcium ions move into the synaptic bulb in order to move the vesicles containing neurotransmitter to the presynaptic membrane.
The tip of the axon terminal enlarges toward the end and acquires the name synaptic end bulb as it gets closer to the muscle fiber. The motor neuron's synaptic end bulb makes up the nervous system portion of the neuromuscular junction. The chemical transmitter acetylcholine (ACH) is pushed inside the synaptic cleft thereafter.
In the postsynaptic or post-junctional membrane, ACH diffuses across the synaptic cleft and binds to specific receptors. Synaptic vesicles in the end bulb are packed with a neurotransmitter molecule. A neurotransmitter is released into a little area called the synaptic cleft when a nerve impulse moves up the axon and arrives at the end bulb.

Explanation:
Photosynthesis is a chemical process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, and water, using light energy in chloroplasts. During the process of photosynthesis, both light and dark reactions occur in the chloroplast. The light responses depend on light to produce organic energy molecules (ATP and NADPH) which are stimulated by chlorophyll (green-colored pigment) while the dark reactions are light-independent.

O They're individually transferred between cells during reproduction.
O They're passed along on the surface of cells during reproduction
They're on the chromosomes that are combined during reproduction
O They're transferred from only a single parent during reproduction
Answer:
The correct answer is C. Genes are the units of heredity, and they are present on chromosomes.
Explanation:
Chromosomes are the structures that carry genetic information in the form of DNA. When cells divide during reproduction, they pass along their chromosomes to their daughter cells. This means that the genes on these chromosomes are also passed along and inherited by the next generation. This is how traits are inherited from one generation to the next.

if the reverse transcriptase enzyme carried by a retrovirus was mutated and nonfunctional, how would the virus be affected?
The virus wouldn't be able to make DNA to ingest into the genome of the host.
As the first step in the creation of an infectious, lytic virus, excision of the prophage DNA from the host chromosomal DNA can occasionally result in the removal of some of the host cell DNA, which is packaged into defective bacteriophages; part of the bacteriophage DNA is removed and replaced at the other end by a gene of the host bacterial species. This type of virus is known as a transducing phage because, after infecting a bacterial cell, it can transfer the gene it has captured via phage DNA to the subsequent bacterial cell it infects.
