Answers
Answer:
Highlands Rilles Trenches divots
Explanation:
The landforms found on the Moon are craters, mountains, and plateaus. Options A, C, and D are correct.
The moon’s three major landforms are the craters, the highlands, and the maria, but there are many other prominent features on the moon’s surface.
Some impact craters, for example, have bright rays radiating outward from the center of the crater. The moon also has several rilles. Rilles are long, narrow tunnels or trenches.
There is no tectonic plate on the moon. There is no volcanic activity on the moon. Almost all of the mountains on the moon are created by asteroids impacting the past.
At the beginning of the moon’s history, there were many large asteroids in the Solar System.

- In a ____________ mutation a DNA base is changed which results in a different amino acid
- A ________ mutation results when an amino acid is inserted or deleted causing the entire sequence that follows to be different.
Answers
Answer:
A mutation is a change in DNA that may result in a malformed protein A silent mutation occurs when a nitrogen base in DNA changes, but the associated amino acid remains the same In a missense mutation a DNA base is changed which results in a different amino acid A frameshift mutation results when an amino acid is inserted or deleted causing the entire sequence that follows to be different.Explanation:
DNA, a nucleic acid used to store genetic information, is made up of nucleotides or bases. These pair up as base pairs to make the DNA double helix. During the cell division process, random changes inside the genome can occur.
These mutations cause errors in DNA produced within the cell; and they may involve small single nucleotide polymorphisms where single nucleotides are changed and large-scale additions or deletions involving several genes.

Using the diagram above, in what direction will water flow?
into the cell
out of the cell
into and out of the cell at equal rates
Answers
Answer:
According to the diagram, where there is the highest concentration of solutes in the cytoplasm, the water will flow into the cell.
Explanation:
Taking into account a difference in solutes concentration between the extracellular and intracellular spaces, the movement of water will be from the space with the lowest concentration of solutes to the space with the highest concentration of solutes, which explains the osmosis.
In the diagram, as there is a higher concentration of solutes in the intracellular space —cytoplasm— the water will pass from the outside to the inside of the cell, due to the force generated by a concentration gradient. The movement of water will be maintained until equilibrium of solute concentrations is reached.

) Some students investigated the effect of the different concentrations of sugar in four drinks, A, B, C and D, on the movement of water across a partially permeable membrane. The students: • made four bags from artificial partially permeable membrane • put equal volumes of 5% sugar solution in each bag • weighed each bag containing the sugar solution • placed one bag in each of the drinks, A, B, C and D • after 20 minutes removed the bags containing the sugar solution and weighed them again. (i) The bag in drink A got heavier after 20 minutes. Explain why.
A contains 0.1% sugar solution.
B contains 4.2% sugar solution.
C contains 6.9% sugar solution.
D contains 10.6% sugar solution.
Answers
Answer:
Concentration of sugar in the bag was higher than in the drink or higher concentration of water outside the bag or in the drink boiling tube so water moved in (to the tubing by osmosis.
Explanation:
Concentration of sugar in the bag was higher than in the drink or higher concentration of water outside the bag or in the drink boiling tube so water moved in (to the tubing by osmosis.
The bag in drink A got heavier after 20 minutes because the water from outside traveled inside the bag via osmosis. Therefore, option (A) is correct concentration of the drink.
What is osmosis?The process of osmosis refers to the transfer of water molecules from a solution that contains a high concentration of water molecules to a solution that contains a lower concentration of water molecules. This transfer takes place through the membrane of a cell, which is only partially permeable.
The states of hypertonicity, isotonicity, and hypotonicity are the three categories of osmotic conditions.
Within a live cell, osmosis plays a significant part in the movement of nutrients as well as the excretion of metabolic waste products. Within a cell, it regulates the flow of water and the levels of intracellular fluid so that they are more stable. Osmosis is responsible for both the regulation of cell-to-cell diffusion as well as the preservation of the mechanical structure of a cell.

Cellular respiration occurs in a series of steps. If pyruvate enters the mitochondrion,
how much total energy can we assume will be produced?
8 molecules of pyruvic acid
38 molecules of ATP
2 molecules of ATP
14 molecules of oxygen
Answers
Answer:8
Explanation:
Pyruvic acids are transformed by oxidative decarboxylation into acetyl-CoA, molecules of NADH, and molecules of CO2 when they enter step two of aerobic cellular respiration producing 38 ATP, hence option b is correct.
What is Cellular respiration?
Since it joins or links the Krebs cycle and glycolysis, this procedure is also known as the link reaction or transition step.
One glucose molecule undergoes chemical processes that result in two pyruvic acid molecules, two ATP molecules, ten NADH molecules, and two FADH2 molecules.
Therefore, as a result, we know that the four pyruvic acid molecules make acetyl-CoA, which then enters the Krebs cycle to produce at the end 38 molecules of ATP are formed.

Answers
Answer:
- Eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.
- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as prokaryotes.
Explanation:
According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.
Eukaryotic organisms are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues. Prokaryotic organisms are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles. The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.

Answers
Answer: Liver and then Fatty Acids
Explanation: Because I got it right on the test.
Bile salts, which are necessary for the emulsification and absorption of fats in the small intestine.
What is bile juice?Bile juice is a yellow-green liquid that is produced in the liver and stored in the gallbladder. It is made up of bile salts, cholesterol, and waste products such as bilirubin. Bile helps in the digestion and absorption of fats in the small intestine. It works by emulsifying fats into smaller droplets, which increases the surface area available for enzymes to break them down.
Bile also helps in the absorption of fat-soluble vitamins, such as vitamins A, D, E, and K. Bile is released into the small intestine in response to the hormone cholecystokinin, which is secreted when fatty foods enter the stomach. Inadequate production or secretion of bile can lead to problems with digestion and absorption of fats, such as diarrhea, malnutrition, and deficiencies of fat-soluble vitamins.

Answer:A and D
Explanation:
It’s the USA test prep question
The following data indicate that the statement "the medium rabbit leg is stable and evolution is unlikely to happen" is false. Hence, options A and D are the correct options for the statements.
What is the role of natural selection?Natural selection selects organisms that are best suited to their environment, and these individuals multiply to increase their population size. In this case, generation after generation, the population of short-legged rabbits decreased from 23 to 13. This indicates that the small-legged rabbits were eaten by the predators, resulting in a reduction in their number. The number of middle-legged rabbits did not vary much, so they did not gain a selective advantage, but long-legged rabbits easily escaped from predators, and as a result, they rapidly increased in number, and as a result, the small-legged population declined with the increase in long-legged rabbits.
Hence, the medium leg is stable and evolution is unlikely" is false. Hence, options A and D are the correct options for the statements.

What is a possible reason for extinction?
The number of habitats falls below a critical level.
Too many resources
Less competition
Less number of new predators
Answers
Answer:
The number of habitats falls below a critical level.
Explanation:
The possible reason for extinction is that the number of habitats falls below a critical level. This makes it impossible for organisms to survive.
A habitat is the dwelling place of living organism in an ecosystem. The resources and other materials that ensures the survival of an organism are made available in the habitat. When a habitat begins to thin out and can no longer support organisms, then extinction will ensue.What is one difference between you and a protist?
