Based on the observation that altering the protein concentration changes the protein's availability outside the cells, the scientists should increase the concentration of the protein in the cell’s external environment.

The rate of endocytosis is determined by incubating the cells with various concentration of the protein. Endocytosis is affected by concentration and temperature. Thus, incubation and protein concentration rise alter the rate of endocytosis.

Endocytosis is the biological mechanism through which chemicals enter the cell. The substance to be internalized is surrounded by a cell membrane region, which buds off inside the cell to create a vesicle holding the ingested material. Examples of endocytosis includes pinocytosis and phagocytosis.

Explanation:

The measurement of energy consumption while a person is awake, seated, and inactive is known as resting metabolism or resting energy expenditure. The amount of energy the body needs each unit of time to stay alert yet not moving.

Any increase in resting energy expenditure is crucial to your weight loss efforts because it makes up 60% to 75% of the calories you burn each day.

Walking quickly for two kilometers or riding a bike uphill are examples of intense activities that might boost your metabolism.

Additionally, different body types have varied amounts of muscle and fat, which affects how much energy they require.

Therefore, calories measurement is the amount of energy required by the body to maintain a nonactive but alert state.

Cells may frequently find themselves in an environment with very low extracellular concentrations of substances needed in higher amounts inside the cell. To obtain these needed items, such cells would be most likely to engage in active transport.

A cell is the most basic and fundamental unit of life. It is the building block of all the organisms. Cells can be of two types: prokaryotic and eukaryotic. A prokaryotic is the primitive type of cell with no true nucleus. Whereas, eukaryotic is the cell with true nucleus and cell organelles.

Active transport is the type where substances cross the plasma membrane against their concentration gradient. This means they travel from the region of low concentration to the higher one. For this they require energy and hence the name active transport.

#SPJ1

Answer:

To calculate the amount of money raised for conservation from the sale of firearms during 2020, we'll follow these steps:

Step 1: Calculate the total revenue generated from firearm sales.

Total revenue = Number of firearms sold * Price per firearm

Total revenue = 19,000,000 * $500

Total revenue = $9,500,000,000

Step 2: Calculate the amount of excise tax collected.

Excise tax = Total revenue * Excise tax rate

Excise tax = $9,500,000,000 * 0.11

Excise tax = $1,045,000,000

Therefore, the amount of money raised for conservation from the sale of firearms during 2020, based on the given information, is $1,045,000,000.

The synthesis of sugar molecules through the process of photosynthesis requires energy absorbed from sunlight. Bearing this in mind, what kind of reaction is photosynthesis? A particular chemical reaction is exergonic.

What is Photosynthesis?

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Have a great day! :)

The synthesis of sugar molecules through photosynthesis requires energy to be absorbed from the sunlight. Bearing this in mind, photosynthesis is an exergonic chemical reaction.

Photosynthesis is the process of formation of sugars in the chloroplast of plant cells. The synthesis requires energy which is absorbed from the sunlight. This sunlight is trapped in the chlorophyll pigment of plant cells. This energy converts carbon dioxide and water into sugars.

Photosynthesis is an exergonic reaction as this reaction releases free energy in the form of sugars (carbohydrates) in the process of the reaction. In exergonic reactions, energy is produced hence the reaction occurs spontaneously. The reactants does not require any energy to react and form product.

The two colored lines on the graph that show the human population reaching carrying capacity are Line B and line C. Thus, the correct option for this question is A.

Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat. the carrying capacity of the habitat must depend on two factors. They are as follows:

Line B and line C are demonstrating the human population that reaching carrying capacity. This is because both these two lines after attaining a certain value must be declining in a gradual manner. This is the attribute of carrying capacity.

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. One hormone could have opposing effects on different organs as e. cells in the different tissues would have epinephrine receptors coupled to different signaling pathways.

It is through the cell signaling pathway that a hormone is able to cause a cell to cause an action. The activity of a cell that is performed under the influence of a hormone depends on cell signaling.

A hormone might cause two opposing actions for different cell types depending on how the cell perceives the hormone through its receptors. As muscle cells require glycogen hence epinephrine couples with receptors that promote this activity in muscle cells through cell signaling. However, it inhibits this activity in the salivary gland due to the coupling with a receptor of salivary gland cells that inhibit this pathway.

The activity of a hormone through cell signaling helps the cell to complete its specialized functions.

Although a part of your question is missing, you might be referring to this question:

Epinephrine inhibits salivary gland activity and muscle cell contraction in the airways, yet stimulates glycogen release in muscle cells and heart muscle cell contraction. How could one hormone have opposing effects on different organs?
