Explanation:

The long, bushy tail of the raccoon may be a selective advantage for this species because the bushy tail helps keep the face warm during a snowstorm (Option d). In addition, it may serve as camouflage and also may act to communicate with other members of the population.

An evolutionary selective advantage is a feature in a species that confer an advantage to survive and reproduce in a particular environmental condition, which may be associated such as in this case to the tail in raccoons.

Therefore, with this data, we can see that an evolutionary selective advantage is any phenotypic feature that enhances the survival and or reproductive rate of individuals in a population or species.

in animals, a nucleotide is employed for conversions of glucose to other carbohydrates. glucose 1-phosphate + phosphoglucomutase >UDP-glucose + pyrophosphate.

By the action of glucokinase or hexokinase and the conversion of ATP to ADP, glucose is transformed into glucose 6-phosphate. Through the required intermediate glucose-1,6-bisphosphate, glucose-6-phosphate is transformed to glucose-1-phosphate by the enzyme phosphoglucomutase. With the help of the enzyme UDP-glucose pyrophosphorylase, glucose-1-phosphate is changed into UDP-glucose. Following the formation of pyrophosphate, pyrophosphatase hydrolyzes it to produce two phosphate molecules. To start off with short glycogen chains that are later extended and branched by the other glycogenesis enzymes, the enzyme glycogenin is required. The anchor for the reducing end of glycogen is a tyrosine residue on each subunit of the homodimer glycogenin. Initial (14) bonds are created by glycogenin by adding roughly seven UDP-glucose molecules to each tyrosine residue.

Cell Theory

The statement that is not part of the cell theory is that every cell has a nucleus that contains genetic material.

In the case of prokaryotic cells, such as bacterias, they do not have a real nucleus, but a specific space in the cytoplasm where the DNA is.

Answer:

The Krebs Cycle, also called the citric acid cycle, is the second major step in oxidative phosphorylation. After glycolysis breaks glucose into smaller 3-carbon molecules, the Krebs cycle transfers the energy from these molecules to electron carriers, which will be used in the electron transport chain to produce ATP.

B. The chlorophyll in the leaves break down, revealing yellow and red pigments that had been masked by the green pigments. This process leads to the beautiful fall foliage colors observed in maple trees. As the weather gets colder, the breakdown of chlorophyll exposes the underlying pigments, creating vibrant red, orange, and yellow leaves.

C. Xylem and phloem fill with ions and organic substances that prevent freezing. In response to increasing cold weather, the tree transports ions and organic compounds into the xylem and phloem. These substances act as antifreeze agents, preventing the freezing of sap and ensuring the circulation of nutrients and water within the tree.

D. Meristems form thick scales to protect next year's buds from cold winter temperatures. The meristems, which are the regions of the tree where new growth occurs, undergo changes in response to the approaching cold weather.

Answer:

A thermos keeps cold things cold in the same way. It doesn't contain some kind of cooling device. The same vacuum that keeps hot things hot keeps cold things cold. Heat that might otherwise transfer to the cold contents of the thermos is prevented from reaching it because of the vacuum between the thermos walls.

Today's thermoses are constructed much more sturdily than those in the past. The first thermoses featured metal exteriors with glass interior walls. These thermoses often ended up getting broken when accidentally dropped.

Teichoic Acids compounds are found associated with the cell walls of gram-positive bacteria but are absent in gram-negative bacteria.

The simplest single-celled organisms are known as bacteria, and they are invisible to the unaided eye. Various animals, including humans, include a wide variety of microbes both inside and outside. Furthermore, bacteria are vital components of the Earth's ecosystems since they are present in food, water, soil, and surfaces.

In actuality, a large number of these species are crucial to our life. The digestion of food by many animals, the growth of trees, and the recycling of nutrients in the environment are all made possible by bacteria. Additionally, they are employed in biotechnology projects that create anything from food to clean water to electricity.

In the human circulatory system, blood always circulates within the vessels, thus being a closed circulatory system. We can distinguish three main types of blood vessels: arteries, veins and capillaries. Blood vessels ensure the transport of blood throughout the body.

The great circulation or systemic, is the path that the blood travels from the heart to the cells of the body and vice versa. In this route, the arterial blood that arrives from the lungs goes towards the left ventricle atrium, then passes through the aorta artery that carries the blood to the tissues of the body.

Answer: A diverse population of bacteria that is treated repeatedly with the same antibiotic and not all of them die will eventually lead to the emergence of antibiotic-resistant bacteria that will thrive and become dominant. The population's antibiotic resistance level before being exposed to the antibiotic was low or non-existent. The "good" bacteria will die while the antibiotic-resistant bacteria will survive and reproduce. After antibiotic treatment, the population's antibiotic resistance level will be higher than before.

Explanation:

Hemophilia is an X-linked recessive trait.

This sickness is presented in males, since they only have one X chromosome, while females are usually carriers and pass on the recessive chromosomes to their children.

It is extremely rare for a female to present hemophilia but not impossible. For a female to have the sickness, she must present the recessive allele in both X chromosomes.

Let "X" represent the normal chromosome and " X' " represent the chromosome with the recessive allele, then a female with hemophilia will have a genotype:

This girl received one recessive allele from her father and one from her mother.

X' from her father → he must be a hemophiliac since males with the recessive allele always present the sickness

X' from her mother → she is a carrier

The X chromosome of males is inherited from the mother, since the mother has two X chromosomes carrying the recessive allele for hemophilia, then all of her children will receive the recessive allele.

This means that all of her daughters will be carriers and all of her sons will have the sickness.

All given options are correct.

Answer:

In monocytes, which are a type of white blood cell, you would expect to find organelles called lysosomes in high abundance to aid in the function of digesting bacteria. Lysosomes are membrane-bound organelles that contain enzymes capable of breaking down various substances, including bacteria, through a process called phagocytosis.

Explanation:

We would expect Lysosomes to be in high abundance in a monocyte to aid in the function of digesting invading bacteria in body fluids and tissue.

Lysosomes are single membrane-bound organelles which are considered as the digestive bags of the cell. They contain a variety of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatases which digest molecules like carbohydrates, fats, proteins, nucleic acid etc

Monocytes are a variety of leukocytes which can differentiate into macrophages. These macrophages participate in the host immune response. When any foreign substance such as a microbe is encountered, the monocytes/ macrophages come into play and engulf it. Once engulfed, the digestion is carried out by the Lysosomes and thus the threat of infection is mitigated.

Smaller and slower axons are those related to temperature, itching and pain.

Explanation:

As you may already know, the axon is an extension of the neuron that has the ability to transmit signals to cells, indicating the nerve impulse that must be felt by the body. In other words, the axons receive a synapse, which is the nerve impulse, and pass this message on to a nerve cell to turn it into a sensation. These axons have varying diameters and the speed at which they transmit messages also varies. According to researches, the smaller and slower axons are those related to the sensation of temperature, itching and pain.
