Research the types of cells present in the kidney.

Answers

The kidney has many different types of cells in it: 1) blood vessel cells

2) cells of connective tissue: this holds the different kidney tissues together
a) adipose (fat) cells
b) fibroblasts producing collagen and ground tissue

3) functional cells: these pertain to the filtration of blood plasma into urine.
a) glomerular cells: these are very thin squamous cells with special "slits" in them to filter (the first part of the nephron.
b) cuboidal tubular cells: these are squarish (cube-like) cells that make a stricter filtering layer, the 2nd part of the neuron.
c) squamous tubular cells: also in the tubule of the nephron, these cells help to filter water and some electrolytes.

4) urothelial cells: these cells are at the end of the nephrons, the collecting ducts, and into the urinary spaces (calyces and renal pelvis)
It contains a specialized type of cell that has smooth muscle under it for contraction.

5) macula densa cells: these are important for sensing how much blood is entering the nephrons, which can secrete a hormone to change/regulate that bloodflow.

6) smooth muscles in front of every nephron: these tiny strips of smooth type of muscle cells is wrapped around the tiny blood vessels entering the glomerulus of the nephron. These muscles can contract around the vessels to restrict bloodflow show it be too much.

Answers

In the past, most people would think that our planet could provide us with anything, whatever we did to it. They thought so because the Earth seemed so vast and rich. However, they were wrong. Most resources like water and petroleum or gas are limited and others like forestry take a long time to generate. After the industrial revolution, man had a lasting negative effect on nature. The correct answer is c. The people there could not understand that polluting the soil or the area around the river would influence the river itself. In the older days, effects like pollution were diluted and because the effects were not seen in the same place, many people did not bother about them. But out pollution affects some place in the Earth, it does not go away. The systems in the Earth are intricately connected between them and this refers to pollution too.

A client who had surgery for a laryngectomy is returned to the surgical unit from the postanesthesia care unit. in which position is it most appropriate for the nurse to place the client at this time?

Answers

Answer: The appropriate position the nurse should do is the side-lying position and the semi-Fowler position helps to maintain the head in functional body alignment and facilitates respiration; also gravity moves the abdominal organs down and away from the diaphragm, facilitating respiratory excursion. Oral intake should not be attempted until the return of the gag reflex because the client could aspirate. Although some slight irritation may occur following this test, there is usually no painful squeal; oral intake would not be withheld because of painful swallowing, although the consistency of food may be changed. The statements that the performance of the graduate nurse is inappropriate because the client may be anxious or thirsty are not correct; additional factors must be considered.

The case of little albert is used by behaviorists to explain ____.
a. ​obsessive-compulsive disorder
b. ​generalized anxiety disorder
c. ​posttraumatic stress disorder
d. ​phobias

Answers

The answer is D. phobias. The little Albert experiment demonstrated that emotional responses can be conditioned in human beings. The 9 months boy was exposed to different stimuli which included a rabbit, masks, a white rat, burning newspapers and a monkey. After some time he was exposed to the white rat and later a loud noise of metal was made and it scared the boy. This exposure was repeated and eventually the boy became afraid of white furry things including animals.

Final answer:

The case of Little Albert is used by behaviorists to illustrate how phobias can be learned through classical conditioning.

Explanation:

The case of Little Albert is used by behaviorists to explain phobias. This classic experiment performed by John B. Watson and Rosalie Rayner demonstrated how a previously unfeared object, such as a white rat, could become a source of intense fear through the process of classical conditioning.

Little Albert developed a conditioned response of fear toward the rat, which was associated with the loud noise that had been paired with it. Although unethical by today's standards, the study highlighted how phobias could be acquired through environmental experiences and conditioning, rather than being innate.

Behaviorists argue that phobias are specific fears of a certain object, situation, or activity, and are characterized by their specificity and their irrationality.

Unlike generalized anxiety disorder (GAD), where the anxiety is more diffuse and is not linked to specific triggers, or obsessive-compulsive disorder (OCD), characterized by repetitive thoughts and behaviors aimed at reducing anxiety, phobias are marked by avoidance of particular stimuli that provoke intense fear.

in complete dominance, when does the dominant trait show up?

Answers

In COMPLETE dominance, the dominant trait shows up when the dominant allele is present.

In INCOMPLETE dominance, the dominant trait does not show up. What shows up is a middle ground between the dominant and recessive traits.

In CODOMINACE, both the dominant and recessive traits are present.

In complete dominance, the dominant trait appears whenever at least one dominant allele is present in the individual's genotype. This differs from incomplete dominance or codominance, where the expression of traits can be a blend or co-expression of both alleles, respectively.

In complete dominance, the dominant trait will show up whenever the individual has at least one dominant allele for the trait. Essentially, in complete dominance, the phenotype of the heterozygous progeny equals the phenotype of the homozygous dominant parent. This form of inheritance is characterized by the fact that a single copy of the dominant allele is enough to exhibit the dominant trait in the offspring. In contrast, recessive traits require the individual to have two copies of the recessive allele to be displayed. Unlike incomplete dominance, where neither allele is completely dominant and the phenotype is a mixture of both alleles, or codominance, where both alleles are fully and simultaneously expressed, complete dominance involves one allele being fully dominant over the other.

How can the absence of wolves affect elk population

Answers

Elk would overpopulate because no wolves are eating them and the food web would change because of the wolves not eating the elk.
An absence of the wolf predator to prey on the elk would cause the elk population to increase dramatically, as there would no be longer the threat of wolves to the elk. This would lead to an overpopulation of elk. Once the elk population increased severely, the elk would start to die out due to insufficient sustenance available to sustain all the elk.

Even though it may seem that the absence of wolves is better for the elk population's survival, in actuality, the wolves keep the elk population in check, and ensure their population doesn't grow too big for their environment to sustain.

Skin color in humans is an example of a phenotypic trait that is determined by polygenic inheritance. three separate gene loci determine skin color (p, q and r), where each gene locus has an additive effect on skin color and the capital letters represent incompletely dominant alleles producing dark skin. what fraction of the children of a medium-toned (ppqqrr) mother and medium-toned (ppqqrr) father would exhibit the lightest possible skin color(genotype: ppqqrr)?

Answers

1/64 is the answer. Polygenic inheritance occurs when the characteristics is under the control of two or more genes. In the presence of large number of genes it is very hard to differentiate the effect of each individual gene in accordance to the Mendelian rules. 

Example, There are 3 genes let us designate with X, Y, Z. Each goes in two alleles. One express the trait (capital) and the other cannot express (lower case). These can have an additive effect. xx cannot contribute to trait and Xx genotype cane contribute to trait and AA would express more of the trait. The same thing would happen to other genes Y, Z.
Final answer:

The fraction of children with the lightest possible skin color in this case is 1.

Explanation:

Skin color in humans is determined by polygenic inheritance, meaning that it is influenced by multiple genetic factors. In this case, three gene loci (p, q, and r) determine skin color, with each locus having an additive effect. Capital letters represent incompletely dominant alleles producing dark skin. To determine the fraction of children with the lightest possible skin color (genotype: ppqqrr), we need to consider the inheritance patterns.

Both parents have the same genotype, ppqqrr, which means their children will also have this genotype.Since the alleles for dark skin are incompletely dominant, individuals with the genotype ppqqrr will have the lightest possible skin color.Therefore, all of their children will have the lightest possible skin color, resulting in a fraction of 1.

So, all of the children of a medium-toned (ppqqrr) mother and medium-toned (ppqqrr) father would exhibit the lightest possible skin color.

Why does a plant cell need a cell wall of cellulose whereas an animal cell does not?

The cell wall houses chloroplasts, which animal cells do not need.

Only animals have a cytoskeleton, which serves the same function as a cell wall in plant cells.

Plant cells receive structure from the cell wall to help them remain upright, which animals do not need.

Water and minerals are transported through plant cell walls, whereas animal cells transport water and minerals through the cell membrane.

Red blood cells contain approximately a 2% concentration of solutes. a red blood cell is placed into a solution that contains a 4% concentration of solutes to which the cell is not permeable. what will happen to the red blood cell?

Answers

I believe that the cells will decrease in size as water flows out of it. The red blood cell is hypotonic to the the solution while the solution is hypertonic, therefore, the blood cells losses water osmotically and decrease in size. Water moves from inside the cell to the outside by osmosis. The end result is the shrinking of the red blood cells.
Final answer:

The red blood cell will undergo crenation due to the surrounding hypertonic solution. Water from inside the cell will move out to the solution causing the cell to shrink and possibly leading to the cell's death.

Explanation:

When a red blood cell, which has a 2% concentration of solutes, is placed in a solution with a 4% concentration of solutes to which the cell can't permeate, the environment around the cell is considered hypertonic. This means that the concentration of solutes outside the cell is higher than inside the cell. In reaction to this, water in the red blood cell will move out of the cell to the surrounding solution in an attempt to balance the concentration of solutes. This process is known as osmosis.

As a result, the red blood cells will lose water and shrink, a process called crenation. This concentration of solutes in the cell will increase, making the cytosol denser which can interfere with diffusion within the cell. The functioning of the red blood cell will be compromised and it might lead to the cell's death due to the loss of water and inability to maintain its necessary functions.

How might a person's immune system be affected if a portion of the DNA codes for interferons has mutated

Answers

Hello,

Okay, so if the portion of DNA that coded for IFN was mutated I think that you would be at a higher risk of viral infections since IFN gears cells up to prevent viruses from entering. Hope this helps mark me brainliest!!

Answer:

The immune system will be susceptible to viral infections

Explanation:

The immune system is the body's primary defense against microbial attacks. One component employed by the immune system is INTERFERONS or IFs, which are one of the group of proteins called CYTOKINES that helps tackle viral attacks in the body by interfering with their replication process.

MUTATION is any change in the nucleotide sequence of a DNA. As we know that genes are expressed into proteins, likewise the interferon protein is encoded by a gene. If a mutation occurs that disrupts or changes the sequence of the interferon-encoding gene, this could lead to the formation of a different non-functional protein entirely or a defective interferon protein. Hence, interferon protein will lose its functionality and be unable to stop viral infection.

This will cause the immune system to be vulnerable to any form of viral infection as the primary defense against them has been compromised by mutation.

Answers

I believe the water treatment stated above is micron filtration. Micron filtration is a water treatment method where water is filtered through screens that have microscopic holes. The holes are measured in microns and the smaller the hole the more contaminants can be removed.

Answer:

Option D, micron filtration.

Explanation:

Micron filtration is a process of water clarification in which waste or impure water is passed through a set of sieve which can be of any pore size depending upon the impurity type i.e the size of contaminants or micro organism

However in reverse filtration water is force to passed through a semipermeable membrane on application of pumping force. Distillation is a physical process of cleaning in which mixture is separated based on difference in boiling points and chlorination is addition of chlorine or its compounds.

Thus, option D is correct.

Having an extra finger is a dominant condition. a woman is homozygous dominant for an extra finger and her husband is homozygous recessive. what phenotypes do the offspring have and in what proportions

Answers

Answer:100% offspring has extra finger

Let say that the dominant gene for extra finger is F and the recessive gene if f. That means the parent genetic would be:
Mother: homozygous dominant = FF
Possible allele: 100% F

Father: homozygous recessive= ff
Possible allele: 100% f

Since the father has 100% chance to give f allele and the mother has 100% of giving F allele, then the offspring would be:
100% Ff (heterozygous). Since the extra finger condition is dominant, a heterozygous individual will express the extra finger condition.

When atp is used by a cell to provide the energy for cellular work, the usual end products left over from the atp molecule are ________?

Answers

When atp is used by a cell to provide the energy for cellular work, the usual end products left over from the atp molecule are ADP

Explanation:

Like every other living thing that needs energy to survive the cells also needs energy for the proper functioning of the organism. Through Cellular respiration the cells derive energy in the form of ATP molecules.  

Adenosine triphosphate (ATP) releases energy to the required cell by transferring one phosphate and then becoming Adenosine diposphate (ADP).

Then after it releases energy it is all set up to absorb another phosphate molecule to become ATP. And this is the simple process of acquiring and transferring energy to the cells.

Final answer:

When ATP is used by a cell, it turns into adenosine diphosphate (ADP) and inorganic phosphate (Pi), releasing energy for cellular functions.

Explanation:

When ATP (adenosine triphosphate) is used by a cell to provide the energy for cellular work, the usual end products left over from the ATP molecule are adenosine diphosphate (ADP) and inorganic phosphate (Pi).

This process is often referred to as the hydrolysis of ATP. ATP is split by the addition of a water molecule, a process that releases a substantial amount of energy which can then be used by the cell for various functions, such as movement, active transport, or chemical reactions.

Hemispheres made of extensive stonework were first used by the Romans. All around its perimeter, the dome exerts thrusts, therefore the earliest colossal versions, like the Roman Pantheon, needed strong supporting walls.

Using a technology developed by Byzantine architects, domes may be raised on piers, allowing for lighting and communication in all four directions.
