The inflammatory response is an innate reaction to invasion by a pathogen regardless of whether that pathogen had been previously encountered. Which statement best describes the symptoms of redness and swelling at the site of a splinter after its removal? A) Interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling. B) Interactions of the respiratory and immune systems create an increased breathing rate and immune cell metabolism, which can lead to redness and swelling. C) Interactions between the immune system and digestive system increase the digestive enzyme activity at the site of the infection, which leads to redness and swelling. D) Interactions of the immune system and nervous system lead to increased cellular communication and hormonal activity at the site of the infection, which causes redness and swelling.

Answers

Answer:

it's A

Explanation:

USATestprep

The statement that best describes the symptoms of redness and swelling at the site of a splinter after its removal is the interactions of the circulatory and immune systems create an increased blood flow and immune cell metabolism, which causes redness and swelling.

What do you mean by Pathogen?

Pathogens may be defined as microorganisms that are responsible for the causation of various diseases, infections, and disorders.

When a splinter attacks your body, your body identifies that it is a foreign substance, it will activate the immune response through the skin and causes redness in association with the circulatory system by increasing the blood flow.

Therefore, it is well described above.

No decorrer das semanas, a lua apresenta diferentes aspectos. A causa para essas mudanças na aparência do satélite da terra é: A) a sombra da terra refletida sobre a lua. B) o movimento de rotação da lua em torno do seu próprio eixo. C) os raios solares que incidem na superfície da lua. D) a translação da lua ao redor da terra.

Answers

Answer:

C) the sun's rays that fall on the moon's surface.

Explanation:

The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.

Answers

Answer:

Both creates new cells

Explanation:

Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.

What is meiosis?

Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.

In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.

Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.

When plants with red flowers are crossed with plants with blue flowers, sometimes only red flowers are produced; other times either red or blue flowers are produced. Which gene is dominant?

Answers

wait what???????????????

Answer:

The colors you see in flowers come from the DNA of a plant. Genes in a plant's DNA direct cells to produce pigments of various colors. When a flower is red, for instance, it means that the cells in the petals have produced a pigment that absorbs all colors of light but red.

Explanation:

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
