In the conversion of glucose and O2 to CO2 and H2O, which molecules become reduced?

The correct answer is A. Mutation.

Mutation provides all the raw material for evolutionary forces to act on. Mutations are random changes in an organism's genetic material (DNA). They can be caused by various factors such as errors during DNA replication, exposure to radiation or chemicals, or even spontaneous changes.

Mutations introduce new genetic variations into a population. These variations can lead to differences in traits among individuals. Evolutionary forces such as natural selection, genetic drift, and gene flow act upon these variations, determining their fate in a population over time.

Selection (B) refers to the process by which certain traits become more or less common in a population based on their impact on survival and reproduction. It acts on existing genetic variations but does not provide the raw material itself.

Genetic drift (C) is the random change in allele frequencies in a population due to chance events. It can lead to the loss of certain variations or fixation of others, but it does not create new genetic material.

Gene flow (D) is the movement of genes from one population to another through migration and interbreeding. While it can introduce new genetic material to a population, it is not the primary source of raw material for evolutionary forces.

In summary, while selection, genetic drift, and gene flow are important evolutionary forces, mutation is the fundamental process that generates new genetic variations, providing the raw material for these forces to act upon.

The endocrine system and the nervous system are both important in regulating bodily functions and responses.

The endocrine system transmits information using chemical signals, also known as hormones, which are released by glands and travel through the bloodstream to target organs. The nervous system, on the other hand, uses both chemical and electrical signals to transmit information.

The chemical signals are called neurotransmitters, and the electrical signals are called action potentials.

The nervous system is responsible for regulating many bodily functions, including movement, sensation, and cognitive processes. Both systems work together to maintain homeostasis and coordinate responses to external stimuli.

Gary's mistake is in the statement that a clockwise rotation of 90 degrees followed by a translation of 2 units to the right will make the angles coincide. This statement is wrong, and in the following paragraph, we will explain why.To understand Gary's mistake, we first need to understand the different types of transformations.

The three most common types of transformations are translation, rotation, and reflection. A translation is a transformation that moves an object from one location to another without changing its shape or size. A rotation is a transformation that turns an object around a fixed point called the center of rotation.

Reflection is a transformation that flips an object across a line called the line of reflection.Now, let's look at Gary's statement. He said that a clockwise rotation of 90 degrees followed by a translation of 2 units to the right will make the angles coincide.

Answer:

Gibberellin

Explanation:

I've studied that gibberellin is a plant hormone that promotes cell elongation and division, causing the cells in the leaves to elongate and divide more, this leads to an increase in leaf size.

Hope it helps! :)

The plant hormone that helps in increasing the leaf size is the phytohormone Auxin .

Plants create signalling molecules called plant hormones, which are found in low concentration. All  plant's growth and progression are regulated by plant hormones.

There are basically five types of plant hormones that are considered to be essential for plant growth . They are Auxin , Cytokinin , Gibberellin , ABA , Ethylene .

The Cytokinin and Auxin work together to enhance the development of leaf as both of the phytohormones are responsible to modulate the growth of leaf as well  as controlling the cell cycle . These hormones are considered essential for plant growth and it occur naturally at various concentrations within plants throughout the duration .

The resting membrane potential depends on two factors that influence the magnitude and direction of Na+ and K+ diffusion across the plasma membrane.

These two factors are concentration gradient and selective membrane permeability.

The concentration gradient refers to the difference in the concentration of ions or molecules between two adjacent regions. It is one of the two primary factors that influence the movement of ions across the cell membrane. The concentration gradient is the driving force that causes the ions to move from the region of higher concentration to the region of lower concentration. In the case of Na+ and K+ ions, they move from the region of high concentration to low concentration.

Selective membrane permeability refers to the property of cell membranes to permit the movement of certain ions or molecules while restricting the movement of others.

The ancestors of cetaceans, including dolphins and whales, were mammals with hair that helped to insulate the body and maintain stable body temperature even in cold climates.

However, today's cetaceans are hairless, even those that live in extremely cold water. This loss of hair can be explained by natural selection. The reason behind the loss of hair can be attributed to a change in the environment and their lifestyles over time. The hair might have become a disadvantage over time because cetaceans are well adapted to aquatic life. Hence, they no longer require insulation from their hair in cold water. Natural selection is responsible for this adaptation. Adaptation is an important part of natural selection.

Through this process, the environment and the organism interact in a way that results in the emergence of traits that help the organism survive better. The environment provides selective pressure, and the organisms that are better adapted to the environment survive and reproduce, passing their advantageous traits to their offspring.The loss of hair in cetaceans was likely the result of natural selection and genetic mutations that favored animals with less hair. As the aquatic life of cetaceans became more significant, the adaptation of less hair would provide an advantage over hair as hair would have presented more disadvantages than advantages.

It is true that when a mature ovum erupts from its follicle, it is triggered by a spurt of fsh. lh. estrogen. progesterone.

The rupture and release of the dominant follicle from the ovary into the fallopian tube, where it has the potential to be fertilised, is what is known as ovulation. Fluctuating levels of gonadotropic hormones (FSH/LH) control the ovulation process. The third stage of the larger uterine cycle, or menstrual cycle, is ovulation. The follicular release occurs after the follicular phase, which is the development of the dominant follicle, and before the luteal phase, which is the maintenance of the corpus luteum and leads to either endometrial shedding or implantation. If the hypothalamic-pituitary-ovarian axis activity is properly regulated, follicular release takes place in a cyclic manner about 14 days before menstruation.
