During an exercise, the process that is causing the burning in your muscles is the production of lactic acid in anaerobic respiration.

Exercise refers to any activity that involves planned, structured, and repetitive bodily movements that are performed in order to maintain or improve the physical fitness of the body.

During exercise, the rate of cellular respiration increases, and similarly the rate of breathing increases.

At a point during the exercise, where the rate of oxygen consumption by the muscles exceeds the rate at which it is replenished during breathing, the cells of the muscles switch from aerobic respiration to anaerobic respiration.

During anaerobic respiration in the muscle cells, lactic acid is produced. The production of lactic acid in the muscles results in a burning sensation in the muscles as well as producing feelings of fatigue.

Answer:

8 chromosomes in each daughter cell

Explanation:

Mitosis creates identical cells. If there are 8 chromosomes in the parent cell, there will be 8 chromosomes in each daughter cell. The way it works is that in late Interphase, the number of chromosomes and DNA double. In this case there would be 16 chromosomes. And when the cell splits into two during cytokinesis, each of the two would get half the chromosomes. Hence, there would be 8 chromosomes in each daughter cell.

Explanation:

Answer:

No

Explanation:

No, plants do not take in air with their roots. Roots are designed to absorb water and minerals from the soil. In order to get the air and carbon dioxide they need for photosynthesis, plants have specialized structures called stomata in their leaves and stems that allow air to enter and exit. These stomata regulate the movement of gases into and out of the plant, so the plant can take in the carbon dioxide it needs and release the oxygen it produces.

Stem cell treatment, commonly referred to as regenerative medicine, uses stem cells or their byproducts to encourage the body's natural ability to heal damaged, sick, or malfunctioning tissue. It is the next phase of organ transplantation and replaces donor organs, which are scarce, with cells.

The type of treatment, the illness or condition being treated, and indeed the stage of the illness can all affect the likelihood of success of stem cell therapy. Stem cell therapy is generally regarded as a secure and efficient treatment option for a variety of illnesses.

These help in reproduction process for a human female.

What are the functions of female reproductive parts?

The internal female reproductive parts are mainly comprised of uterus, ovaries, fallopian tube, cervix and vagina.

The women reproductive machine is the frame components that assist ladies or human being assigned women at birth ( AFAB) to have sexual intercourse, reproduce and menstruate.

They basically produce gametes called eggs, sex secreting hormones called estrogen. This is the place where fertilisation takes place and the baby survives here, if fertilisation has taken place. In the end, it is the place where a mother gives birth to the baby.

Answer:

The correct answer would be - 200 to 300 protein-producing genes.

Explanation:

According to the studies, there are many genes that do not produce proteins and have no direct role in cellular functioning. According to the human genome project, there are 20000 to 25000 genes present in a human cell.

According to the study and researches, the minimum number of genes a single-celled organism needs to divide or reproduce itself and survive in the laboratory is approximately between 265 and 350.

Thus, the correct answer is - 200 to 300 protein-producing genes.

Answer:

The correct answer is - facilitated diffusion.

Explanation:

Facilitated diffusion is a form of facilitated transport of molecules such as amino acid, glucose, and others through the plasma membrane involving the passive or indirect movement of molecules along their concentration gradient, which is led by the presence of another molecule normally a pore or channel made up of integral protein.

Facilitated diffusion depends on several factors such as the size of molecules, type of molecules, similarity of molecules to extracellular matrix or fluid that slow or fast the diffusion process.

Thus, the correct answer is - facilitated diffusion.

Agriculture is an important sector of the U.S. economy. The crops, livestock, and seafood produced  in the United States contribute more than $300 billion to the economy each year.[1]  When food-service and other agriculture-related industries are included, the agricultural and food sectors contribute more than $750 billion to the gross domestic product.

Explanation:

Agriculture and fisheries are highly dependent on the climate. Increases in temperature and carbon dioxide (CO2) can increase some crop yields in some places. But to realize these benefits, nutrient levels, soil moisture, water availability, and other conditions must also be met. Changes in the frequency and severity of droughts and floods could pose challenges for farmers and ranchers and threaten food safety.

This is because the temperature of body increases and by which the excess water from body comes out from our body in the form of sweat...

No, the type of animal does not determine at which trophic level that organism exists. They could be at any tropical level. The trophic level of an organism is determined by its diet, not its species.

Trophic levels are the levels of the food chain where an organism obtains its energy.

The first trophic level consists of producers are plants. They get their energy directly from the sun through photosynthesis.

The second trophic level is made up of herbivores, or animals that eat plants.

The third trophic level consists of carnivores that eat herbivores, and the fourth trophic level consists of carnivores that eat other carnivores.

The combinations that are feasible are AA, Aa, and aa since each parent contributes one allele. Aa people display the recessive trait, whereas offspring with either an AA or an Aa genotype will have the dominant phenotype expressed phenotypically.

The total number of boxes in your Punnett Square should be counted. You are then provided with the estimated total number of offspring. Subtract the (phenotype's prevalence in the population) from (the total number of offspring). To get your %, multiply the value from step 4 by 100.
