Answer:
d. All of these answer choices are correct.
Explanation:
Viruses have an exterior coat composed of protein, the capsid. Inside of it, there is DNA or RNA. When the virus has RNA, it has an enzyme that allows the synthesis of DNA from RNA. This type of virus is a retrovirus since it does the inverse process, from RNA, it gives DNA and not the other way round.
First, as the capsid has proteins, it attaches to a receptor in the cell's membrane. Then the DNA or ARN enters the cell taking it as a host since it uses the cell's structure to replicate the viral DNA and make viral proteins and DNA that then it assembles to form new viruses that will be released to infect other cells.

What geologic process creates an alcove
A) glaciation
B) wind erosion
C) tectonic uplift
D) coastal erosion
Answer:
wind erosion
- i know this question is older but i hope this helps anyone who may need it. :-)
The geologic process that creates an alcove is wind erosion, which is present in Option B, as the alcove is a recessed area in a rock or cliff face that is often semicircular in shape.
What is wind erosion?Alcove is created by the process of wind erosion. Over time, wind can carry abrasive particles, such as sand or small rocks, that erode the softer rock on the face of a cliff, carving out a hollow space. As the wind continues to erode the rock, the hollow can deepen and expand, forming an alcove. Alcoves are often found in areas with strong, consistent winds, such as desert regions, and can range in size from small niches to large, room-sized spaces. In addition to wind erosion, alcoves can also be created by other geologic processes such as water erosion or tectonic activity.
Hence, the geologic process that creates an alcove is wind erosion, which is present in Option B.

What is cell theory?Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

What kind of material is transported through osmosis?
Answer: water
Explanation: Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.
Pay attention to what happens to the things around you as you go about
your day. Describe three examples of Newton's third law in action (use
different ones from those described in the lesson). In your examples
describe the action and the equal and opposite reaction.
Answer:
Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices. Two other examples are: As a professor paces in front of a whiteboard, he exerts a force backward on the floor. A car accelerates forward because the ground pushes forward on the drive wheels, in reaction to the drive wheels pushing backward on the ground.

Which statement describes an advantage of sexual reproduction over asexual reproduction?
Answer:
One advantage is that secual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.
Explanation:
One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.
What is sexual reproduction?When sperm from a male parent fertilizes an egg from a female parent during sexual reproduction, the result is an offspring that is genetically distinct from both parents.
The genetic diversity of organisms is a result of sexual reproduction. Meiosis, a process that creates sperm and egg cells, is the first step in sexual reproduction.
Because they have half as many chromosomes as the parent, these cells are known as haploids. A diploid zygote is created during sexual reproduction when a male parent's haploid sperm fertilizes a female parent's haploid egg.
Therefore, One advantage is that sexual reproduction provide variation which can help living things survive in different environment. Asexuals cannot have variation.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.

A. the production of sugar
B. the release of energy
C. the removal of waste products from the cell
D. the formation of new proteins for the cell
The main function of the process of cellular respiration is the the release of the energy. The correct option is B.
What is cellular respiration?Cellular respiration is a biochemical process that disintegrate glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.
Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glycolysis is the first step in the process by which cells generate ATP from food. Consider eating a donut. Digestive enzymes convert the donut's starches and sugars to glucose (blood sugar) in your mouth and stomach.
The aerobic process by which living cells break down glucose molecules, release energy, and form ATP molecules is known as cellular respiration.
In general, this three-stage process involves the reaction of glucose and oxygen to form carbon dioxide and water.
Thus, the correct option is B.

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth. The ocean's tidal energy causes water to cycle on the earth. The water from the oceans evaporate and form precipitation. The precipitation then condenses back on the surface of the earth. The earth's magnetic energy causes water to evaporate. The water condenses into water vapor once it becomes precipitation. The condensation then falls back to the surface of the earth. The sun's thermal energy causes water vapor to condense. This condensation then forms precipitation. This precipitation returns to the atmosphere for the cycle to continue.
Answer:
The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.
Explanation:
The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth.
Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.
The ocean's tidal energy does not cause water to cycle on earth.
