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

Answers

Answer 1

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.

A storm brings two formerly separated populations of beetles together. They look very similar. Under the biological species concept, which of the following would show that the two populations are different species?
A. One population breeds in spring, the other in fall.
B. Males of the two populations have different flight patterns in courtship.
C. When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch.
D. All of the above is correct.
E. None of the above is correct.

Answers

Answer:

The correct option is D: All of the above is correct.

Explanation:

The biological species concept says that species are population groups that, in a real or potential way, can reproduce among each other and that are reproductively isolated from other groups.

Individuals belonging to a species cannot mate with members of other species, and if they do there is not any reproductive success.    

The mechanisms of reproductive isolation might be divided in prezygotic and postzygotic.

Prezygotic or Premating mechanisms:

Ecological or due to habitat isolationSeasonal or temporal. This is the case described in option A "One population breeds in spring, the other in fall". These species are reproductively isolated because they differ in their breeding season.Sexual or ethological. This is the case described in option B "Males of the two populations have different flight patterns in courtship". Males belonging to each species behave differently during courtship. MechanicalGametes incompatibility

Zygotic or Postmating Mechanisms:

Hybrid inviability. This is the case described in option C which states that "When individuals from the two populations mate with each other in the laboratory, the eggs fail to hatch". Eggs fail to hatch because the zygote is inviable. Hybrid sterilityHybrid decreased fertility

Which of these must exist for natural selection to cause change ?

Answers

Answer:

The answer is A.

Explanation:

Which of the following best expresses the concept of natural selection?
A) differential reproductive success based on inherited traits
B) inheritance of acquired characteristics
C) change in response to need
D) a process of constant improvement, leading eventually to perfection
E) survival of the fastest

Answers

Answer:

The correct answer is - option A. differential reproductive success based on inherited traits

Explanation:

Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.

The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.

Thus, the correct answer is - option A. differential reproductive success based on inherited traits

Due to genetic changes and the environmental conditions when the organism adapts itself to the current situation for survival is called natural selection.

Natural selection means that the organism that survived over another have better traits and characteristics for adaptation.

The correct answer is:

Option A. differential reproductive success based on inherited traits.

This can be explained as:

A particular type of trait carried by an organism that is better for adapting to survival than the other organism carrying less favorable trait will have a better chance of survival and their reproductive success will be much higher.

Based on the inherited characteristics the natural selection will be based on reproductive success.

Differential reproductive success is an analysis in which comparison is done among the organism that survived and those that did not.

Comparing their traits and characters can give an idea about the factor affecting the selection.

Therefore, differential reproductive success based on inherited traits best expresses natural selection.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption

Answers

Answer:

constructive interference

Explanation:

when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.

When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.

What is the constructive interference?

Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.

When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.

Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.

Therefore, constructive interference  best describes what happens if two waves meet and build on each other.

Answers

Answer:

there must be large numbers of free amino acids present in the cytoplasm

Explanation:

In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.

These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.

During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.

Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

Answer:

O. Wave A has a higher frequency because it has a  shorter wavelength.

Explanation:

Wavelength refers to the distance between two crests while frequency refers to the number of waves passes through a specific point per second. Frequency and wavelength are inversely proportional to each other. Inversely proportional means if one increases, the other decreases and vice versa. If the frequency of the wave is higher so its wavelength becomes shorter and if the frequency of the wave is shorter so its wavelength is higher.
