Explain why eating a meal with too much salt leads to production of small volume of concentrated urine.
Answer:
the urine is burned up by salt which will evaporate
Answer:
Eating a meal with too much salt leads to a decrease in the water potential of blood. This fall in water potential is detected by the osmoreceptors in the hypothalamus (in brain). The hypothalamus stimulates the pituitary gland to release antidiuretic hormone (ADH). The walls of the collecting duct in the kidney become more permeable to water, hence, a greater proportion of water is reabsorbed from the urine back into the blood by osmosis.
As a result, a small volume of concentrated urine is formed.

List some characteristics of each type of seismic wave. Include what type of material (solids, liquids, or both) each can travel through. Primary wave: Secondary wave: Love wave: Rayleigh wave:
Answer:
The primary wave or the P wave is the fastest kind of seismic wave. These waves can travel through the fluids like the liquid or the water layers of the Earth, and solids rocks. It pulls and pushes the rock it moves through similar to the sound waves that pull and pushes the air. These waves are also called compressional waves, due to the pulling and pushing they do.
The secondary wave is also known as the S wave is slower in comparison to a P wave, and possess the tendency to move through the solid rock, however, not through any kind of liquid medium. The characteristic of the S wave helped seismologists to conclude that the outer core of the Earth is a liquid. The S waves help in moving the particles of rock side to side perpendicular to the direction of the wave or up and down.
The Love wave and Rayleigh waves are the two kinds of surface waves. These waves possess lower frequency in comparison to the P and S waves. Of the surface waves, the Love waves are the fastest surface wave and move the ground from side to side.
On the other hand, a Rayleigh wave rolls around the ground similar to the rolling of the waves across an ocean or a lake. Both these waves only travel through a solid medium.

The paranasal sinuses are lined with a membrane that creates mucus during allergies or the common cold. Presence of mucus and swelling of the membranes can cause a "sinus headache." If Regina has a cold and she feels the pain of a sinus headache inferior to her eyes, which bone is housing the affected paranasal sinus?
Answer:
The maxillary sinus, that is, the sinus located in the upper jaw, would be affected.
Explanation:
Sinusitis is a very traditional disease that is associated with headache, discomfort, and increased mucus making.
The causes can be viral or bacterial or even by some inhaled noxa, sinusitis of this type is bilateral, different from sinusitis of dental cause that are usually unilateral.
The paranasal sinuses are the sinuses that pneumatize the head, that is, they generate an internal air current in the bones to be able to heat and disinfect them from those noxas that are inhaled (that is why they are covered by a ciliated mucosa that drags the noxa to the outside and also its structure is pseostratified with mucous cells that secrete mucus enveloping the noxa).
Another function of the paranasal sinuses is to be able to alleviate the weight of the head, since the shell and the bones that remain in the head formation are very heavy, thus generating these cavities filled with air to alleviate the feeling of "heavy head" "When they become inflamed and filled with mucus, they are obliterated or with a reduced space, so the head feels heavier for some people.
The paranasal sinuses are the maxillary sinuses that are in the upper jaw, the sphenoid sinuses that are in the sphenoid, the ethmoid sinuses that are in the ethmoid and the frontal ones that are in the frontal bone that is vulgarly called as the forehead.

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

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.

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.

Answer:
hydroshere
Explanation:
hydro=water
Answer:
you're answer would be hydrosphere
Explanation:
Life on Earth, emerged in the hydrosphere, at least from the findings and data so far. The reason for that was that the atmosphere and the lithosphere were still in a faze were they were not very hospitable for any living organisms to develop. The hydrosphere, or the water bodies, on the other side, were enabling conditions for life, not perfect or as we have today, but still reasonably good, so the life started developing into the water environment, and after the atmosphere and lithosphere changed over time, it spread on them as well.

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
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.

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.
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 incompatibilityZygotic 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 fertilityWhat is the main function of the human immune system?
