Explain why the HEART RATE of the students increased after exercise. Include information about what happens at the level of body systems and at the cell.

Answers

Answer:

When exercising, your body uses more oxygen and produces more carbon dioxide and your muscles also need energy to contract because of this your breathing needs to increase.

Hope this helps :D

Answer:

for why the heart rate increase is because during exercise alot energy is used which means alot of oxygen also used for respiration ,the cells need oxygen to meet the demand of energy so breathing rate increase then to transport oxygen faster then the heart rate also increases.

Which of the following is correct about mutations and genetic variation?

It must be present in a population before natural selection can act upon the population.
It arises in response to changes in the environment.
It tends to be reduced when diploid organisms produce gametes and reproduce.
It is created by the direct action of natural selection.

Answers

Answer:

a. It must be present in a population before natural selection can act upon the population.

Explanation:

Genetic variation is the difference in the DNA sequences in individuals, which makes a member of a species different from another member of the same species. It can also be said to be the differences in the genetic make up of individuals of a species population.

Genetic variation must be present in a species population before evolutionary mechanisms, such as evolution, can occur. Genetic variation must be present in a population of a species before natural selection can act upon the population, as natural selection can only increase or reduce the frequency of alleles present in the species population already.

Genetic variation in a population of species is important for natural selection to occur.

The true statement is that; "genetic mutation must exist before natural selection can act on it."

What is natural selection?

The term natural selection refers to the fact that traits that are more favorable to enable an organism to survive and reproduce tend to persist in the population.

These traits usually occur due to genetic mutations. In a population, genetic mutation must exist before natural selection can act on it.

Which of the following statements is correct? Which of the following statements is correct? The sperm and egg have twice as many chromosomes as the parental cells. Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division. Meiosis results in gametes that are used in reproduction. Asexual reproduction requires the production of eggs and sperm.

Answers

Answer:

Meiosis results in gametes that are used in reproduction.

Explanation:

The sperm and egg have twice as many chromosomes as the parental cells. INCORRECT. Sperm and eggs are the gametes, and they have only half the number of chromosomes that can be found in the germ cells or somatic cells. Gametes are haploid, n. Geneticists use the terms "son" and "daughter" to distinguish between cells resulting from cell division. INCORRECT. The term "daughter cells" is used to refer to the products of cell division. "son cells" is not used at all. Meiosis results in gametes that are used in reproduction. CORRECT. Germ cells are the reproductive, diploid cells produced by testes and ovaries. After meiosis, each germ cell produces four haploid cells that are the gametes. Gametes´ destiny is to merge during fecundation, creating a new diploid cell called the zygote. The zygote is a diploid cell that suffers successive mitosis to form the new organism.Asexual reproduction requires the production of eggs and sperm. INCORRECT. Only sexual reproduction needs gametes. Cells that reproduce asexually duplicate their genetic material and cytoplasmic content and then divide, producing a new cell identical to its parental. This is the case of binary fission, for example.

explain the differences between the particles of a pure substance and the particles of a mechanical mixture

Answers

Answer:

A substance is pure if it is a single substance, and it is made up of only one type of particle. If there is more than one substance, and therefore more than one type of particle, it is a mechanical mixture, the particles can be easily distinguished, due to their non-uniform composition. The composition of a mechanical mixture is variable and their components may be separated by physical or mechanical means because they are not chemically bound.

Explanation:

A pure substance is one that has a composition and characteristic properties that do not change, whatever the physical conditions in which it is found; that is, the physical transformations do not affect it. In other words, pure substances will be made up of particles that are identical to each other. Mechanical mixture are the result of the physical union of two or more substances which are called components, these can be elements or compounds, whose particles do not mix uniformly. The components of the mixtures have different properties, such as the state of aggregation, the density or the solubility. These properties allow substances to be identified and facilitate the separation of the components of a mixture, that is, through physical or mechanical processes we can isolate and obtain the components that make up the mechanical mixtures.

What explains two green pea pod plants producing 25% plants with yellow
pea pods? (green is dominant, yellow is recessive)

Answers

Answer:

two heterozygous pairs

Explanation:

the genotype products of Gy and Gy would be GG, Gy, Gy, and yy, making a 25% chance for yellow

The heterozygous pairs are those that have different alleles in the two chromosomes a and a re a set of the dipole individual.  

The 2 green pea pod plants produce 25% of the yellow sea pods where the green is the dominate and yellow is recessive. As the chromosome is inherited in both the parent the gene is same. Thus the dominant green color and yellow pod plants will have a mix of genes.

Field mustard is an annual plant that grows wild in many regions of the world. It has small yellow flowers and is pollinated by insects. Field mustard has to flower and produce seeds to give rise to the next generation. Southern California experienced a severe drought between 2000 and 2004. Plants that flowered earlier reproduced. Those that flowered later died without producing seeds. This led to more early-flowering field mustard plants. This change in population characteristics took only a few generations.
How do you think scientists discovered that the flowering time of the field mustard had changed?

Answers

Answer:

Mustard adapts quickly to climate fluctuations

Explanation:

Instead, the post-drought seeds gave rise to plants that flowered earlier than those of the pre-drought seeds, even in the greenhouse, confirming that the shift in flowering time really was due to an underlying change in the plants' genetic program.

Compare and contrast genetic engineering to the process of natural selection. Select all statements that are true

Answers

Available options are:

1. By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.

2. Unlike natural selection, genetic engineering selects the organisms most beneficial to the environment.

3. By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.

4. Like natural selection, genetic engineering may be used on all organisms, including humans.

5. The effects of genetic engineering apply only to the organism selected, but natural selection affects the entire population.

Answer:

1, 2, and 3

Explanation:

Given that Genetic engineering is a scientific process of altering the genetic makeup or elements of organisms such that these organisms develop preferable traits.

On the other hand, Natural selection is a process that deals with the impartial selection of traits, that is without human input, thereby making organisms more fitted to their immediate environment.

Therefore, considering the available options, the comparison, and contrast of genetic engineering to the process of natural selection are:

1. By selecting the genetic information that is passed on to future generations, genetic engineering is similar to natural selection.

2. By selecting the genetic information that is passed on to future generations, genetic engineering can happen at a different rate than natural selection.

3. Like natural selection, genetic engineering may be used on all organisms, including humans.
