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.

Answer:

D

Explanation:

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

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.

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

Answer: d. segregation

Explanation: i did it:)

The fact that each plant gets only one allele from each parent plant is detailed in the law of segregation. The correct option is D.

The law of segregation, also known as Mendel's first law, explains how pairs of alleles segregate during gamete formation in parents and recombine during fertilisation to form the genotype of offspring.

According to the law, two alleles for each gene segregate from each other during gamete formation, so that each gamete receives only one of two alleles.

This segregation ensures that each offspring inherits only one allele from each parent, and it serves as the foundation for the dominance and recessiveness principle, which states that one allele may mask expression of another.

The law of segregation explains how, in the given scenario, the offspring of a cross receive only one allele from each parent, resulting in all offspring being either Tt or TT and exhibiting the dominant phenotype of tallness.

Thus, the correct option is D.

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.

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.

For microorganism to grow and form a population, they require both chemical and physical requirements. The chemical requirements required are gas such as oxygen and also mineral elements. The elements that are required are nitrogen and phosphorous.  The physical elements required include the temperature of the environment. According to temperature organism are classified into three groups. Psychrophilic microorganisms are found in the cold temperatures, mesophilic are the ones which are found in the moderate temperatures and the thermophilic are found in areas with high temperatures.

Microorganisms require nutrients, moisture, and an appropriate temperature range to grow and reproduce. These conditions facilitate the exchange of matter with the environment, which is vital for their life processes.

To ensure their growth and reproduction, microorganisms require certain conditions to be met. Three crucial things they need are:

By having access to these basic needs, microorganisms can exchange matter with the environment, which is critical for them to grow, reproduce, and maintain organization.

A circular or elliptical anticline structure is called a 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.

Starch is broken down into the disaccharide maltose, which consists of two glucose molecules. This process is facilitated by the enzymes amylase and maltase.

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.

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.

The proportion of the subsequent generation with brown eyes is 0.91.

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.

Final answer:

Chemoorganotrophs and photoautotrophs would not compete for light energy as they have different energy sources, with the former relying on organic compounds and the latter on sunlight for photosynthesis.

Explanation:

A chemoorganotroph and a photoautotroph in the same environment would not compete for light energy, because chemoorganotrophs do not rely on light. Instead, they obtain energy by oxidizing organic compounds. In contrast, photoautotrophs like plants and algae use sunlight to convert carbon dioxide and water into organic compounds, a process known as photosynthesis. Therefore, these two types of organisms have different nutritional requirements and energy sources, reducing direct competition between them.

Chemoautotrophs are distinct from photoautotrophs because they extract energy from inorganic chemical compounds rather than from sunlight. Both types of autotrophs produce organic matter from carbon dioxide, but the source of energy for that process is different. Chemoautotrophs often thrive in environments devoid of sunlight, such as deep-sea hydrothermal vents, where they can utilize the chemical energy available from substances like hydrogen sulfide (H₂S).

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.
