Answer: Chloroplast

Explanation:

Plants and some algae have chloroplasts responsible for photosynthesis. Plants undergo photosynthesis to transform light energy into chemical energy. This energy is stored in the form of sugar to support their growth and provide energy. Chloroplasts have a double membrane, with the thylakoid membrane located within the inner membrane.

Photosynthesis occurs within the thylakoid membrane, which is folded into sacs called thylakoids. Chlorophyll, a green pigment, is present in the thylakoids and it absorbs light energy to split water molecules into hydrogen and oxygen. The oxygen is released into the atmosphere while the hydrogen is used to create ATP, a molecule that stores energy. ATP and hydrogen are then utilized to make sugar, the final product of photosynthesis.

Explanation: Scientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.

Answer:

A

Explanation:

Geographic isolation is a crucial component in speciation. If gene flow is disrupted for an extended period of time due to the geographical obstacles, populations can develop separately and eventually form different species.

Three coats enclose the optically clear aqueous humour, lens, and vitreous body in the eye.

The cornea and sclera form the outermost coat; the choroid, ciliary body, and iris form the middle coat, which contains the main blood supply to the eye and extends from the back to the front.

The eye functions as a sensory organ. It collects light from our surroundings and converts it into nerve impulses. The optic nerve sends these signals to the brain, which creates an image and thus provides sight.

Thus, as per the labeling number, Vitreous gel, Optic Nerve, Macula, Fovea, Retina, Lens, Pupil, Cornea, Iris respectively are the parts of eye.

The process of mitosis helps to repair a wound by allowing the body to produce new cells to replace damaged or lost cells.

Mitosis is the process of cell division that produces two identical daughter cells from a single parent cell. During mitosis, the DNA in the parent cell is replicated, and the two copies are separated into the two daughter cells. This ensures that each daughter cell receives a complete copy of the genetic information necessary for the proper functioning of the organism. In the case of a wound, the body activates mitosis in the surrounding cells to produce new cells to replace the lost or damaged cells. This process helps to repair the wound and restore the integrity of the tissue. In summary, the process of mitosis helps to repair a wound by allowing the body to produce new cells to replace damaged or lost cells.

Explanation:

Edge 2021

Answer:

Skeletal muscles are full of long protein fibers (actin and myosin).To build more muscle, the cells will need more amino acids to build these two proteins.

Explanation:

The correct option is "To build more muscle, the cells will need more amino acids to build these two proteins (actin and myosin)." Amino acids are the building blocks of proteins, and muscle growth is primarily driven by an increase in muscle protein synthesis. Consuming sufficient amounts of dietary protein, which is broken down into amino acids in the body, is important for providing the raw materials needed for muscle growth and repair. However, the other options provided in the question are not accurate. While amino acids can be used for energy, they are not the only type of fuel that muscle cells can use, and skeletal muscles do not use amino acids to make glycogen stores (glycogen is a form of stored glucose, not amino acids).

(a) Synonymous mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A synonymous mutation occurs when a gene changes its nucleotide sequence but the amino acid sequence remains unchanged. An example of this type of mutation using AAGTGC is AAGTGT. The translated sequence would still be Lysine (AAG) and Cysteine (TGT). This is because TGT is a codon for Cysteine, so the amino acid sequence remains unchanged.

(b) Non-synonymous missense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous missense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is also changed. An example of this type of mutation using AAGTGC is AAGTGA. The translated sequence would be Lysine (AAG) and Glutamic acid (TGA). This is because TGA is a codon for Glutamic acid, so the amino acid sequence is changed from Cysteine to Glutamic acid.

(c) Non-synonymous nonsense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous nonsense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is changed to a stop codon. An example of this type of mutation using AAGTGC is AAGTAA. The translated sequence would be Lysine (AAG) and Stop codon (TAA). This is because TAA is a codon for Stop codon, so the amino acid sequence is changed from Cysteine to Stop codon, which causes the protein to be truncated.

Drugs known as calcium channel blockers can be used to decrease the force of cardiac contraction, which indirectly decreases stroke volume. This can be helpful in certain situations, but individual circumstances should be evaluated by a healthcare professional.

Drugs known as calcium channel blockers can be used to decrease the force of cardiac contraction. When calcium channel blockers are used, they block the entry of calcium into the muscle cells of the heart. This reduces the contractility or force of contraction of the heart, leading to a decrease in stroke volume.
Stroke volume refers to the amount of blood pumped out of the left ventricle of the heart with each heartbeat. By reducing the force of contraction, calcium channel blockers indirectly decrease stroke volume.
To put it simply, calcium channel blockers make the heart contract less forcefully, which means it pumps out less blood with each beat. This can be beneficial in certain conditions where the heart needs to work less, such as in cases of high blood pressure or certain heart conditions.
However, it's important to note that calcium channel blockers can have various effects depending on the specific drug and the patient's condition. Therefore, it's crucial to consult a healthcare professional for personalized advice and guidance regarding the use of these drugs.
In conclusion, drugs known as calcium channel blockers can be used to decrease the force of cardiac contraction, which indirectly decreases stroke volume. This can be helpful in certain situations, but individual circumstances should be evaluated by a healthcare professional.

If the left side of the beaker has a greater concentration of urea than the right side, then A, water will leave the right side of the beaker by osmosis and join the left side of the beaker.

Osmosis occurs in this instance because there is a difference in the concentration of urea between the left and right sides of the beaker. Urea is a solute that cannot pass through the selectively permeable membrane, but water molecules can.

This is because water moves from an area of low solute concentration to an area of high solute concentration in order to equalize the solute concentration on both sides of the membrane.

Rett syndrome is an X-linked dominant disorder that means a dominant allele is required to affect the individual, but this condition is not applied to females.

An Allele may be defined as one or two or more alternate forms of a particular gene.

In Rett syndrome, Females require both the dominant form of alleles to cause the disorder i.e. \(X^HX^H\), while \(X^HX^h\) is a condition of carrier females.

In the case of males, there is only one X-chromosome, so only one dominant allele is sufficient to cause the disorder i.e. \(X^HY\).

Lac Operon is defined as an operon that is used by E.coli for transporting and metabolizing lactose.

Allolactose is a disaccharide like lactose, that binds to lac repressor and restrict its binding with DNA. It triggers expression of a operon or gene.

So, adding allolactose to the bacterial growth media, block the activity of lac repressor and trigger the activity of bacteria to metabolize the sugar lactose.

Hence, the correct answer is "A."

Based on the current understanding of this operon hypothesis would be useful for James to test addition of all lactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose. Thus, option A is correct.

The bacteria reproduces through the process of asexual reproduction and the amoeba reproduces through the process of binary fission. Reproduction is defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.

There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

Purple flowers are a dominant trait, so a pea plant only needs one allele for purple flowers in order to have the trait. White flowers are a recessive trait, so a pea plant needs two alleles for white flowers in order to have the trait. If a plant has both a dominant allele and a recessive allele then the dominant trait of purple flowers will be expressed.

When a trait has two separate gene-level versions, there are dominant and recessive traits. The trait that emerges initially or is most obviously displayed in the organism is its dominant trait. Recessive traits are those that are present in the organism but are not visible at the gene level.
