Answer:
Via cytotoxic cells. When a virus infects a person (host), it invades the cells of its host in order to survive and replicate. Once inside, the cells of the immune system cannot 'see' the virus and therefore do not know that the host cell is infected.

what are some drawbacks to using mice in genetic studies?
Answer:
One drawback to using transgenic, knock-in, and knock-out mice to study human diseases is that many disorders occur late in life, and when genes are altered to model such diseases, the mutations can profoundly affect development and cause early death.
hope this helps
Explanation:
Genetically altered mice have served to recapitulate human diseases, including cancer, glaucoma, heart disease, and diabetes. However, despite their genetic similarity to humans, mouse models are criticized for their failure to accurately mimic human disease phenotypes.
Why it's bad to use mice as an experiment:
The use of mice as model organisms to study human biology is predicated on the genetic and physiological similarities between the species. Mice are less reliable as models of human disease, however, because the networks linking genes to disease are likely to differ between the two species.

Examine the comparison between a eukaryotic cell and a prokaryotic cell. Which two lettered choices provide a comparison of structures that encode genetic information for the cells? A) A and D B) B and D C) C and D D) None of these choices, as prokaryotic cells do not contain DNA
I am almost certain it is A) a and d) but I need reassurance.
Answer: c & d
Explanation:
C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.
What are Prokaryotic and Eukaryotic cells?Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.
Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.
Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

why cellular respiration and photosynthesis are a
cycle.
Cellular respiration and photosynthesis are referred to as a cycle because the end product of one process serves as the starting material for the next reaction. During cellular respiration, sugar and water are the starting materials, and carbon dioxide and water are the byproducts. Water and carbon dioxide are the starting material for photosynthesis.
ExplanationA cycle is a series of steps that are repeated, which defines this! :)
The Forensic Anthropology Facility was founded by whom?
There are no ____________ in the ____________ , located where the nerve fibers of the ____________ leave the eye and enter the ____________ . Consequently, this region of the retina is commonly called the ____________
There are no PHOTORECEPTORS in the OPTIC DISC located where the nerve fibers of the RETINA leave the eye and enter the OPTIC NERVE. This region is commonly called the BLIND SPOT.
The retina is an important layer of nervous tissue that covers the inside of the eye, in which the sensation of vision initiates.
Photoreceptors are specialized cells within the retina that respond to light stimuli. In the retina, there are two types of photoreceptor cells: cones and rods.
The blind spot is a small portion of the visual field of the eye that localizes in the optic disk within the retina.
There are no rods or cones (i.e. photoreceptor cells) within the optic disk.

At 2s, your velocity is 4.5m/s. Calculate your acceleration.
Your Answer:
Answer
units
Answer:
2.25 m/s^2
Explanation:
Acceleration is the speed which you are increasing by per second. Therefore to find acceleration all you need to do is divide the change in velocity (4.5) by the time (2). Your units than become (m/s)/s or m/s^2.
True or False: Because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny.
The statement 'because the microbiome is important for fitness, many organisms have developed specific strategies for passing the microbiome on to progeny' is TRUE. It is natural selection in action.
According to the evolutionary theory proposed by Darwin, natural selection is the mechanism by which species change (evolve) to adapt to particular environmental conditions.
In this case, the microbiome represents an evolutionary adaptive mechanism, thereby natural selection will tend to favor individuals that have a beneficial microbiome.
In consequence, individuals having a beneficial microbiome will have more chances to reproduce and survive (i.e., they have higher adaptive fitness), thereby they also have more chances to pass this adaptive trait to the next generation.

Say that you look at the nuclei of 100 skin cells taken from the same person. About how many of these skin cells would you expect to be in interphase
Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

The left cerebral hemisphere controls the muscles on the right side of the body and vice versa. Which pathway generalization best explains this phenomenon
Given our understanding of neuroanatomy, we can confirm that the left cerebral hemisphere controls the muscles on the right side of the body and vice versa due to the motor decussate of the cortical spinal pathway.
A decussate in regards to the nervous system is described as when the nerve fibers cross from one side of the central nervous system to the other. The decussate in question corresponds to the cortical spinal motor decussate.
The cortical spinal pathway is the nerve pathway that is in charge of muscular control and therefore is the pathway that is responsible for the phenomenon described in the question.

As wind passes over a mountain, the side over which the wind rises tends to be ____________________ and the side that experiences the downward movement of air tends to be ____________________.
drier; moist and rainy
moist and rainy; drier
rainforest; desert
desert; rainforest
Given what we know about the effects of air currents on mountain ranges we can confirm that the correct option is option B, moist and rainy on one side while being dier on the other.
Mountains are described as having two sides in regards to their relationship with the air currents. The side of the mountain on which the wind rises is known as the windward side, whilst the side on which air descends is known as the leeward side. The windward side is typically in contact with warmer, moist air from the ocean and other bodies of water.
When coming in contact with the mountain, the air is forced to rise and begins to cool, which often leads to rain or snow. The leeward side of the mountain receives the air that has now already lost the majority of its moisture with its pass through the windward side of the mountain. This air also tends to become warmer as it descends, which explains the dry nature of the leeward side of mountains.
