The evolutionary outcome of adding a mutagen to a population of C. elegans composed only by hermaphrodite individuals would be the emergence of genetic variations in the population.

C. elegans, also known as Caenorhabditis elegans, are free-living, transparent nematodes or roundworms found in soil samples, compost heaps, and rotting vegetation. C. elegans are one of the most studied species in the laboratory, and they are frequently used as a model organism to study developmental biology, genetics, and neurobiology.A mutagen is any agent that induces heritable DNA modifications in living organisms. Mutagens are known to cause genetic mutations, and they can be either natural or artificial agents.

When mutagens interact with the DNA of an organism, it induces chemical alterations that can lead to mutations, and these changes in the DNA can be transmitted to offspring during cell division or reproduction. Adding a mutagen to a population of C. elegans composed only of hermaphrodite individuals would result in the introduction of genetic variations in the population. Since hermaphrodite C. elegans are homozygous for most genes, meaning they have two identical alleles for the majority of their genes, the introduction of mutations would have a greater effect on the population's genetic makeup than it would on the genetic makeup of a heterozygous population.

Answer:

A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion.

The terms "origin" and "insertion" in relation to muscles describe the two places where a muscle attaches to bones or other body parts.

The place of solid or fixed attachment of a muscle is known as its origin. This is the starting point of the muscle, where it contracts very rapidly. Typically, the origin is the bone that is more stable or located closer to the center of the body.

The dynamic attachment point of a muscle is called an insertion. This is where the muscle ends and attaches to a bone that moves in response to muscle contraction. In most cases, the insertion is located away from the center of the body or the more mobile bone.

Answer: Age 5.

Explanation: Incredibly, it doubles in size in the first year. It keeps growing to about 80% of adult size by age 3 and 90% – nearly full grown – by age 5. The brain is the command center of the human body.

According to neuroscience, the human brain reaches 90 percent of its adult weight at around the age of six years.

Although the brain remains to grow for several years, the vast majority of its growth occurs in the first few years of life. The growth of the brain takes place more in terms of development than in size. The increase in brain size in the early years of life is mostly because of the growth of neural connections. A child's brain continues to develop and grow over time and adolescence, however, the pace of growth decreases with age as the number of neural connections reduces.

In the first two years of life, the brain doubles in size and continues to grow rapidly until about the age of six years. The brain reaches almost its full adult size by the time a person is six years old. However, the neural connections in the brain continue to develop throughout life as the brain experiences new things and learns new skills. Thus, the human brain never stops changing, and it is capable of growing and adapting throughout the individual's lifespan.

If the person produces an allele with a dominant trait after meiosis (the process of cell division that produces gametes, such as eggs and sperm), the expected percent chance is 50%.

If a person is heterozygous for a certain trait, that means they have two different alleles (versions of a gene) for that trait, one inherited from each parent. One of the alleles is dominant and the other is recessive. This is because during meiosis, the alleles for a particular trait are separated and distributed randomly to the gametes.

As a result, there is an equal chance of either the dominant or recessive allele being passed on to the offspring. Therefore, if a person is heterozygous for a trait, they have a 50% chance of producing an allele with a dominant trait and a 50% chance of producing an allele with a recessive trait.

The sugar molecule represents the most stored chemical energy. Thus, the correct answer is Option B.

Sugar (glucose, C₆H₁₂O₆) is a biological molecule that stores energy in its chemical bonds, not the molecule that initiates the process of cellular respiration During cellular respiration, glucose is broken down in a series of chemical reactions to produce energy ATP (adenosine triphosphate).

The process of cellular respiration begins at the stage of glycolysis, where glucose in the cytoplasm of the cell is partially broken down into pyruvate molecules and then the pyruvate molecules are broken down again in the presence or production of oxygen (aerobic respiration). fermentation in the absence of oxygen depending on whether oxygen is present

During aerobic respiration, pyruvate enters mitochondria and undergoes the citric acid cycle (also known as the Krebs cycle) and the electron transport chain These processes release energy from glucose chemical bonds to produce more ATP.

Therefore, sugar (glucose), although it stores energy in its chemical bonds, is not the molecule that initiates cellular respiration. Instead, during cell respiration, glucose is broken down and energy is released in the form of ATP.

The inside of Euglena has high concentration of water as Euglena is freshwater organism and lives in aqueous environment. Concentration of solutes inside Euglena is lower than that in surrounding water, meaning that Euglena is hypotonic relative to its environment.

Water flows from the environment into Euglena through a process called osmosis and this movement of water across the cell membrane occurs in order to equalize concentration of solutes on both sides of membrane.

After osmosis occurs, size of Euglena may increase due to influx of water.  Euglena has contractile vacuole, which is responsible for regulating water balance of cell. Contractile vacuole pumps excess water out of cell and preventing it from bursting.

One adaptation that Euglena has to maintain its water balance is the presence of pellicle, which is a rigid layer of protein strips that surrounds  cell membrane. Pellicle provides structural support to cell, protecting it from changes in osmotic pressure.
