Explanation:

Answer:

carbon dioxide (CO2) and water (H2O) from the air and soil, and sunlight

Explanation:

Answer: Carbon Dioxide, Water, and Sunlight

Explanation:

    The equation for photosynthesis is

CO2 (carbon dioxide) + H2O (water) = Glucose (sugar) + O2 (oxygen)

It takes the energy from the sun and converts water & CO2 to create glucose and oxygen. Glucose and oxygen are the products of the equation. Therefore, to create them, you only need CO2, H2O, and the sun!

This toxin binds to the sodium-potassium pump, blocking action potentials and causing paralysis or neurological disruption.

This toxin would cause the neuron to become depolarized and unable to fire action potentials. The neuron would be unable to generate new action potentials, leading to paralysis. This toxin could be used to paralyze a neuron or a whole network of neurons, effectively blocking any potential nerve signals from the affected area. It could also be used to disrupt the normal functioning of the nervous system, leading to a wide range of neurological symptoms.

Answer:

The body systems functions together for the wellbeing of an organism

Explanation:

The percentage of muscle fiber types in a muscle is influenced by genetic factors, but physical activity and training can also cause adaptations and slight changes in muscle fiber type composition. The relative amount of each muscle fiber type can vary among individuals and can be different depending on the specific demands of their sport or event.

In the thigh muscles of Olympic athletes participating in different events like the marathon, weightlifting, and the 100-meter dash, we can expect to see variations in the distribution of muscle fiber types.

Marathon runners typically rely heavily on endurance and sustained effort, which requires a high aerobic capacity. Therefore, they often have a higher percentage of slow-twitch (Type I) muscle fibers. Slow-twitch fibers are fatigue-resistant and are well-suited for prolonged, low-intensity activities.

On the other hand, weightlifters need explosive strength and power for their sport. They typically have a higher proportion of fast-twitch (Type II) muscle fibers, particularly Type IIa and Type IIb. These fast-twitch fibers generate high force but fatigue more quickly than slow-twitch fibers. Weightlifters may have a higher proportion of Type IIb fibers, which are specialized for short, intense bursts of power.

Sprinters participating in the 100-meter dash require explosive speed and power. They also have a higher proportion of fast-twitch muscle fibers, including a significant percentage of Type IIb fibers. These fibers can generate rapid force production and are optimized for brief, intense activities.

It's important to note that while there are general trends in muscle fiber type distribution among athletes in specific sports, there can still be individual variation based on genetic factors, training history, and other factors. Athletes' training regimens and genetic predispositions can influence the specific percentages of muscle fiber types observed in their thigh muscles.

Answer:

The acentric fragment gets lost during anaphase I

Explanation:  

There are different kinds of structural chromosomal abnormalities. One of them is the formation of a shorter chromosome and an acentric fragment. By deletion, it might occur a fragment loss in a segment of a chromosome. The chromosome breaks, resulting in a much shorter chromosome, plus a smaller fragment without centromere.

As the acentric fragment does not have a centromere, so during division, it will not be properly directed to one of the poles, and hence, it will be lost during the process of cellular division.

Contraceptive pills suppress ovulation and keep oestrogen levels low throughout the menstrual cycle, preventing pregnancy.

The contraceptive pill contains synthetic hormones that mimic the effects of oestrogen and progesterone in the body.

These hormones work to suppress the natural production of oestrogen by inhibiting the release of follicle-stimulating hormone (FSH) and luteinising hormone (LH) from the pituitary gland.

This prevents ovulation and therefore reduces the levels of oestrogen that are normally produced during the menstrual cycle.

The low levels of oestrogen between days 8 and 22 of the menstrual cycle in women taking contraceptive pills are due to the fact that this is the time when oestrogen levels would normally peak in a natural menstrual cycle.

However, as ovulation is suppressed by the pill, there is no need for the body to produce high levels of oestrogen to support the development of the ovarian follicle.

Instead, the pill maintains a consistent level of synthetic hormones throughout the cycle, which prevents the fluctuation of oestrogen levels that would occur naturally.

Therefore, women who take contraceptive pills typically have lower levels of oestrogen throughout their menstrual cycle.

Based on the given information, the top consumers in the food chain would be the coyote and the red fox.

A food chain is a representation of the feeding relationships between different organisms in an ecosystem. It shows how energy and nutrients are transferred from one organism to another through consumption.

In a food chain, each organism occupies a trophic level, which represents its position in the chain based on its source of food. At the base of the food chain are primary producers, such as plants or algae, which produce their own food through photosynthesis. Herbivores, which feed on primary producers, occupy the next trophic level.

These animals are positioned at the highest trophic level in the food chain, indicating that they consume other organisms but are not themselves preyed upon by any other organisms in the given food chain.

Therefore, the correct selections from the organisms provided are the coyote and the red fox.

Axon carries messages away from neuron and dendrite is the branch of neuron that receives messages.

Dendrites are appendages that are designed to receive communications from other cells. They resemble a tree-like structure, forming projections that become stimulated by other neurons and conduct the electrochemical charge to the cell body.

Dendrites receive input from many other neurons and carry those signals to the cell body. If stimulated enough, a neuron fires an action potential — an electrical impulse that then stimulates other neurons. Large networks of these neurons communicate with each other to generate thoughts and behavior.

The dendritic passive properties, such as axial resistance, diameter, branching, and the distance of the synapse from the soma, enable neurons to perform a wide range of computations on their inputs.

Male and female fetuses are generally indistinguishable until around the ninth week of gestation, or the end of the embryonic period. Prior to this, all embryos develop in a similar way, with the same basic body plan and structures.

During the ninth week of gestation, sexual differentiation begins to occur as the fetal gonads (ovaries or testes) begin to form. The gonads then release hormones that trigger the development of secondary sex characteristics, such as the formation of the male or female genitalia.

In male fetuses, the testes begin to produce testosterone, which leads to the development of the male reproductive system, including the scrotum. In female fetuses, the ovaries do not produce testosterone, and the external genitalia develops into the labia.

While sexual differentiation occurs in the ninth week of gestation, it is not until later in the pregnancy that the external genitalia can be visualized on ultrasound and the sex of the fetus can be determined with a high degree of accuracy.

It is also important to note that not all individuals fit into the binary male/female sex categories, and intersex conditions can occur where there are variations in sex development.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars (by cellulase in certain fungal species), the resulting glucose monomers are properly defined as the products

The correct answer is option E.

When the carbohydrate cellobiose is digested into two glucose monosaccharide sugars by cellulase in certain fungal species, the resulting glucose monomers are properly defined as the products.

In a chemical reaction, reactants are the starting materials or substances that undergo a change, while products are the resulting substances formed after the reaction. In this case, cellobiose is the substrate, which is the molecule that undergoes the enzymatic reaction. Cellulase is the enzyme responsible for catalyzing the digestion of cellobiose into glucose monomers.

The enzyme cellulase acts as a catalyst in the reaction, facilitating the breakdown of cellobiose into glucose. Catalysts are substances that increase the rate of a chemical reaction without being consumed or permanently changed themselves. However, in the context of the given question, the glucose monomers produced are the final result or product of the enzymatic digestion process.

Therefore, in the digestion of cellobiose, the resulting glucose monomers are correctly identified as the products (option E).
