During osmosis A) pure solvent diffuses through a membrane but solutes do not. B) pure solutes diffuse through a membrane but solvent does not. C) pure solvent and a solution both diffuse at the same time through a membrane. D) gases diffuse through a membrane into a solution and build up pressure.

Answer:

Explanation:A.

The net movements of solvent from the region of higher water potential (solvent) to a region of lower water potential(solute) through  a semipermeable membrane is called osmosis. It is a peocess where the solute dissolved in the solvent and the resulting solution pass the selective permeable membrane,A selective permeable is  the type which allows water,gases, and  non polar molecules to pass through, but restrict polar and other large molecules  through its walls.

Generally during osmosis,the water molecules and solute molecules interacts.These interaction ,due to dipole dipole effects of the water molecules, reduced the pressure of water on the solute in solution .Consequently, the water molecule of the pure water (the  solvent )exerts more pressure on the weaker solution i,e higher water potential

Hence,this pressure forces water molecules across the semi permeable membrane,from higher water potential to lower water potential.It is the major biological process of plants and animals.

Answer:

Meiosis

Explanation:

Mitosis creates an identical set of daughter cells to the parent cells through asexual reproduction but meiosis creates a set of sex cells that are identical to each other but not to the parent cell and this is through sexual reproduction.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

According to the research, the correct answer is the enzyme in charge of transcription in bacteria in the synthesis of any RNA is RNA polymerase, unlike eukaryotic cells, in which there are different types of enzymes depending on the type of RNA transcribed .

Bacteria have a single type of RNA polymerase, which is a complex enzyme made up of several subunits, being responsible for transcription, polymerizes in the 5'-3' direction and does not need primers.

In this sense, transcription in eukaryotes is much more complex than in bacteria, it takes place in the nucleus, transcription is carried out by 3 types of RNA polymerases and it has a more complex regulation, in which numerous transcription factors participate that promote the initiation.

Therefore, we can conclude that in eukaryotes, DNA has to bind to transcription factors and there is a great deal of specialization of RNA polymerases, while in bacteria they have a single type of RNA polymerase.

Explanation:

A premise that could be used to back up the conclusion that urchins are undergoing natural selection would be that urchins with short spines are extremely vulnerable to predators. Option C.

Urchins with short spines are extremely vulnerable to predators.

This is because natural selection is a process in which organisms with certain traits are better able to survive and reproduce than those without those traits, and those traits are then passed on to future generations.

In this case, the vulnerability of urchins with short spines to predators means that they are less likely to survive and reproduce, while those with longer spines are more likely to do so.

Therefore, the trait of long spines is being naturally selected for in the urchin population. The other options do not provide evidence for natural selection.

Anaerobic respiration is the term for the breakdown of glucose when there is no oxygen present. When energy from glucose is released, a chemical activity known as respiration takes place in living cells.

In the absence of oxygen, glucose is partially converted to pyruvate. Anaerobic respiration is the name given to this process. Glucose is partially converted into water and carbon dioxide in the absence of oxygen. If all oxygen is removed, fermentation takes place. In anaerobic respiration, bacteria and yeast break down glucose (food) into alcohol and carbon dioxide while lacking oxygen to release energy.

So, we can say that the process of breaking down glucose when there is no oxygen present is known as anaerobic respiration. Living cells engage in a chemical process known as respiration when glucose is converted to energy.

The example that includes only chemical changes that occur in the digestive process is the reaction of saliva, stomach acid, bile, and pancreatic juices with food. Option D.

Chemical changes refer to changes to the chemical properties of substances. In biological reactions, these substances are referred to as reactants.

Chemical changes are different from physical changes. In physical changes, only the physical properties of substances are altered while their chemical properties remain intact.

When a substance changes chemically, its physical properties most often change along. However, this is not in all cases.

Thus, looking at the examples given, their classification into either physical or chemical changes is as follows:

When saliva, stomach acid, bile, and pancreatic juices react with food, the chemical properties of food change because the enzymes convert different components of food from one form to another as part of the process of digestion.

A. mechanical energy.

Mechanical energy is subdivided into 3 other types of energy:

1. potential energy

2. Spring energy

3. Kinetic energy ( that's where lifting of objects falls under)

When we are lifting any object mechanical energy is used and stored in our body. This mechanical energy consists of kinetic energy and potential energy.

What is mechanical energy?

It is the combination of the energy of either an object in motion (Kinetic energy) or the energy that is stored in objects by their position (Potential energy).

Mechanical energy = Kinetic energy + Potential energy

example: steam, wind, water, gas etc.

For example, a moving vehicle possesses mechanical energy in the form of kinetic energy and a compressed spring possesses mechanical energy in the form of potential energy.

As we are raising the object it gains potential energy because it has the potential to be released at any moment with a crash as the weight falls back to the ground and some kinetic energy is supplied by our muscles. When we lower that object this potential energy gets converted into kinetic energy and the energy in our muscles becomes heat.

Hence Mechanical energy is used to lift any object as well as to put it down.

Complete question:

Homogenization of rat liver cells results in the rupture of the cell membranes. Centrifugation of this homogenate compacts some of the homogenates into a pellet at the bottom of the centrifuge tube. Bathing this pellet with a solution containing succinate (a four-carbon organic compound), phosphate ions, oxygen, and ADP yields metabolic activity, including the production of ATP and the uptake of oxygen. This pellet most likely contains

1. peroxisomes

2. mitochondria

3. lysosome

4. Golgi complex

5. endoplasmic reticulum

Answer:

2. Mitochondria

Explanation:

Mitochondria are one of the biggest organelles in the cell. They degrade organic molecules, releasing chemical energy from their bindings through a process that consumes oxygen: cellular respiration.

The released energy is stored as ATP through the cellular respiration process and then is used in other cellular activities.

Mitochondria are more grouped in areas or tissues with higher energetical requirements.

As cellular respiration characterizes by consuming oxygen and producing ATP, we can assume that the pellet mostly contains mitochondria.

By considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.

Cellular respiration is a series of reactions by which aerobic cells consume oxygen and nutrients (e.g. glucose) to produce ATP and carbon dioxide.

Cellular respiration has three sequential steps: glycolysis, the Krebs cycle and oxidative phosphorylation.

Mitochondria are the energy center of the eukaryotic cells. The Krebs cycle and oxidative phosphorylation occur in the mitochondria, while glycolysis occurs in the cytoplasm.

The Krebs cycle produces a four-carbon molecule known as succinate.

Adenosine triphosphate (ATP), the energy coin of the cell, is produced from ADP and phosphate (Pi) in the three stages of cellular respiration.

Finally, oxygen is consumed during oxidative phosphorylation.

In conclusion, by considering the components of the pellet, we can deduce that it most likely contains MITOCHONDRIA.
