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

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.
Starch can be broken down into the disaccharide known as _____. starch can be broken down into the disaccharide known as _____. lactose glucose sucrose fructose maltose
Starch is broken down into the disaccharide maltose, which consists of two glucose molecules. This process is facilitated by the enzymes amylase and maltase.
Explanation:Starch, a form of complex carbohydrate, is broken down into the disaccharide maltose. The process begins with the enzyme amylase, that breaks down starch into smaller fragments, creating a disaccharide known as maltose. Maltose consists of two glucose molecules bonded together. This breakdown further continues in the small intestine with the help of another enzyme, maltase; it splits the maltose into two separate glucose molecules.

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)?
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.

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

A circular or elliptical anticline structure is called a ____.
A circular or elliptical anticline structure is called a dome.
What is dome?In architecture, a dome is a hemispherical structure that developed from an arch and often serves as a ceiling or roof. In the ancient Middle East, India, and the Mediterranean, domes first developed as solid mounds and in methods suitable only for the tiniest structures, such as round houses and graves.
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. Four pendentives, inverted triangular masses of masonry that were curved both horizontally and vertically, were used to connect the cubic base to the hemispherical dome.

Which of the following is best defined as the transfer of genetic information from one population to another?
If 70 percent of the hypothetical population passed along allele b, the dominant allele for brown eyes, and 30 percent passed along allele b, the recessive allele for blue eyes, the proportion of the subsequent generation with brown eyes would be ___________, given the hardy-weinberg equilibrium.
The proportion of the subsequent generation with brown eyes is 0.91.
Explanation:The proportion of the subsequent generation with brown eyes can be determined using the Hardy-Weinberg equilibrium equation. In this case, the equation is: p^2 + 2pq + q^2 = 1
where p^2 represents the proportion of individuals homozygous dominant for brown eyes (allele BB), 2pq represents the proportion of individuals heterozygous for brown eyes (allele Bb), and q^2 represents the proportion of individuals homozygous recessive for blue eyes (allele bb).
Given that 70% of the population has allele B (brown eyes) and 30% has allele b (blue eyes), we can calculate the proportion of individuals with brown eyes as follows:
p^2 = (0.7)^2 = 0.49
2pq = 2(0.7)(0.3) = 0.42
q^2 = (0.3)^2 = 0.09
Therefore, the proportion of the subsequent generation with brown eyes would be 0.49 (homozygous dominant) + 0.42 (heterozygous) = 0.91.

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

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
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.

A postpartum patient tells the nurse, "my baby does not pass soft stools every day." which instruction should the nurse give the patient?
It is pretty normal for infants not to poop every single day. The reason behind this is the complete absorption of milk nutrients. Infants feed on breast milk which is highly nutritious and sometimes body absorbs all the milk leaving a little to move through the digestive tract to intestines.
Hence, It is pretty normal for an infant to poop once in a week.
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?
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.
