Gastrin, histamine, endorphins, serotonin, cholecystokinin, and somatostatin are hormones or paracrines that are released directly into the lamina propria. Which of the following cell types synthesize and secrete these products?
a) parietal cells
b) enteroendocrine cells
c) mucous neck cells
d) zymogenic cells
Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.

The wells that contain the DNA samples are placed next to the negatively charged electrode in the electrophoresis box (chamber) because _______. Group of answer choices DNA strands have both a positive and a negative charge DNA is negatively charged DNA is positively charged DNA has no electrical charge
Answer:
DNA is negatively charged
Explanation:
Electrophoresis: In biology, the term "electrophoresis" is described as one of the different laboratory technique that is being utilized to separate protein molecules, DNA, and RNA one the basis of their electrical charge and size. Therefore, a specific amount of "electric current" is being used to move different molecules that are required to be separated through a "gel". The given gel contains pores that generally works like a "sieve" and thus allows every small molecule to proceed faster as compared to the larger molecules.
DNA stands for "deoxyribonucleic acid" is determined as a long molecule that ought to contain an individual's unique "genetic code" and generally carried information associated for making proteins in an individual's body.
In the question above, the correct answer is "DNA is negatively charged".
The samples of DNA are placed next to the negatively charged electrode in the electrophoresis as DNA is negatively charged.
What is electrophoresis?It is a laboratory technique, which is used to distinguish RNA, DNA or molecules of protein on the basis of their electrical charge and size. In the process, an electric current is utilized to move molecules to be separated via a gel. The gel comprises pores that functions as a sieve, which permits smaller molecules to move faster in comparison to larger molecules.
DNA is a negatively charged molecule, thus, when it is used in the process of electrophoresis, the migration of DNA will take place towards the positively charged electrode. Through the gel, the DNA with shorter strands will move more briskly in comparison to the longer strands leading to the formation of fragments being aligned in order of size.
Thus, the samples of DNA are placed next to the negatively charged electrode as they are negatively charged.

Which of the following is not a method of cell signaling?
A. Short range message molecules
B. Direct contact
C. Hormones
D. Enzymes
Answer:
C: Hormones
Explanation:
hormones do not "signal" other cells. I hope this helps :)
The correct answer is option C. Hormones.
What is the simple definition of hormones?Hormones are chemicals that act like messenger substances in the body. After being made in one part of the body, they move to other parts of the body, where they help control how cells and organs work. For example, insulin is a hormone made by the beta cells of the pancreas.
In endocrine signaling, signaling molecules (hormones) are secreted by specialized endocrine cells and transported through the circulatory system to affect target cells in remote parts of the body.
Hormones are so many essential parts of your body's system that they regulate much of what your body does. Hormones regulate growth, libido, sexual development, reproduction, sexual function, metabolism, and thirst, among other things. They simply tell the body what to do to keep it running smoothly.

What could happen if the cell cycle for the cells in your pinky finger stopped functioning properly? (Check all that apply.)
Answer:
Hello, you did not enter the answer options, but I can help you by explaining what would happen in this case.
if the cell cycle of the cells in your little finger stops working properly, two things could happen. First, if these cells were unable to start and complete the cell cycle, your finger would be unable to heal cuts and bruises that could happen to it, on the other hand, if these cells were unable to end the cell cycle, your finger would develop cancer .
Explanation:
The cell cycle allows the cells of your circus, in this case, of your little finger, to multiply and create exactly the same cells. This process is very important to not only make your finger grow, but also to be able to heal cuts and bruises, regenerating the tissues and skin of your finger.
Unfortunately, over time, or as a result of some factors, cells may have defects in the cell cycle. In short, if the cells are unable to start and complete the cell cycle, your finger will be unable to create new cells and regenerate tissues and skins if your finger is cut or injured. In addition, the cells may not be able to finish the cell cycle and multiply in an exaggerated and unregulated way, generating a cancer in the finger.

A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? The number of adenine bases will be equal to the number of guanine bases. The number of adenine bases will be equal to the total of all the other bases. The number of adenine bases will be equal to the number of thymine bases. The number of adenine bases will be half of the number of cytosine bases.
Answer:
The correct option is;
The number of adenine bases will be equal to the number of thymine bases
Explanation:
The four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism
The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;
Adenine (A) pairing with thymine (T)
Cytosine (C) pairing with Guanine (G)
Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.
Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.
According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.
Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.
More on DNA base pairing can be found here: https://brainly.com/question/19670411
What did Chargaff discover while studying bases in the DNA of organisms?
Answer: The ratios of thymine and adenine were similar, as were the ratios of guanine and cytosine.

Some individuals can be heterozygous for a particular mutation.This means that one of their chromosomes is normal and the other is mutated in some way. Approximately ___ of the gametes produced by an individual heterozygous for a deletion will be non viable.
Answer:
1/2 (50%)
Explanation:
During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring
Damage to Schwann cells would result in Group of answer choices loss of the structural framework of the brain decreased speed of conduction ability to produce scar tissue at the site of an injury increased axoplasmic flow
Answer: decreased speed of conduction.
Explanation:
Schwann cells are type of cells of the peripheral nervous system that produce myelin sheath around neurosonal axons thereby increasing the saltatory function of neurons.
If Schwann cells are damaged it result in blockage of electric conduction which will produce secondary demeylination and resulting in shock or toxic immune shock.
Schwann cells produce myelin sheath will help to increase saltatory conduction but when it is damaged it will decrease conduction and result in shock.
