Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.
Explanation:
The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.

Answer: bone marrow
Explanation: Bone marrow is the soft, spongy tissue that is located in the medullary cavities (centers) of certain large bones. Healthy bone marrow is an essential part of the body, as it contains stem cells that produce blood cells and the cells that make up the immune system.
Answer:
is called bone marrow

Is the spongy tissues inside our bones
Which approach would be least helpful in determining genetic differences between species?
Answer:
the least helpful would be a straight up guess, the best way would be to to back in the history of that species and study how they lived and survived and reproduced and all that stuff
Explanation:
Comparing physical characteristics between species is not a reliable method for determining genetic differences because many physical traits are influenced by environmental factors and may not necessarily reflect the underlying genetic differences between species.
What is an example of this ?For example, two species may have different fur colors or patterns, but this difference may be due to environmental factors such as exposure to different types of light rather than genetic differences.
In contrast, analyzing DNA sequences can provide a more precise and objective way to identify genetic differences between species. By comparing the DNA sequences of different species, scientists can identify variations in genes and regulatory regions that may be responsible for differences in traits or behaviors between species.
This approach can also reveal the evolutionary relationships between species and provide insights into how genetic variation has driven the diversification of life on Earth.
Therefore, Advances in genomic technologies have made it increasingly feasible to sequence and compare the genomes of diverse species. Comparative genomics has already revealed many insights into the genetic basis of traits such as human disease susceptibility, adaptation to environmental challenges, and the evolution of complex traits such as intelligence and social behavior.

What precautions must be taken during the blood borne Pathogens?
The precautions that must be taken the blood borne Pathogens and Other Potentially Infectious Materials are mentioned below:
Some blood borne pathogens are hepatitis B virus, bacteria and some pathogens as well.The finger or the area must be rubbed with the alcohol and must be involved in the daily routine of the hand hygiene.The area that are exposed with the pathogens must be washed with the water and soap. The exposure source must be notified to the lab assistant or supervisor.The individual should not eat or apply anything on the wounded area exposed with the pathogens.The unprotected sex must be avoided to prevent the transmission of the pathogen from mother to the fetus.The potential for the exposure to blood borne pathogens has not present in the almost all workplaces. This danger occurs more than anything in health workers where they have a high risk of coming into contact with body fluids, including blood, of patients with pathology transmitted by this means that it is not valid to be in other types of work, since they would not be part of its risk matrix.

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?
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.
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.
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.
