1. What has to be added to a substance to cause a phase change?

Answers

Answer 1

Answer:

To cause a phase change, you either add heat energy to a substance to cause it to evaporate, melt, or sublimate, or you subtract heat energy, or take it away, to make the substance freeze or condense. Hope it helps!

Explanation:

Answer 2
Phase changes require either the addition of heat energy (melting, evaporation, and sublimation) or subtraction of heat energy (condensation and freezing). ... Changing the amount of heat energy usually causes a temperature change.

All of the following statements support the cell theory EXCEPT?

Answers

All of the following statements support the cell theory except all cells contain a nucleus. Thus, the correct option for this question is B.

What is the Cell theory?

The cell theory was proposed by two famous scientists. i.e. M.J. Schleiden and T. Schwann. There are three assumptions that fall under the cell theory.

All living organisms whether plants or animals are made up of cells. A cell is the smallest unit of all living organisms. It is the basic structural and functional unit of life.

Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells.

According to the three assumptions given above, the one which is not matched as per the options is that all cells contain a nucleus.

Therefore, the correct option for this question is B.

What is cell theory?

Cell theory is basically a biological theory first given in the mid-nineteenth century that states that living organisms are made up of cells, that cells are the basic structural/organizational unit of all organisms, and that all cells originate from pre-existing cells.

According to the cell theory, all biological organisms are made up of cells; cells are the basic unit of life, and all life evolved from preexisting life.

The cell theory is now so well-established that it serves as one of biology's unifying principles.

Theodor Schwann proposed the classical cell theory in 1839. This theory is divided into three parts. The first section asserts that all organisms are made up of cells.

Thus, the correct option is L.

Explanation:

Permeability is the ability of a layer of rock to transmit fluid such as oil or water

The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter

Rocks such as gravels, and  sparingly cemented sands have high permeability

The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water

Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy

Answers

Answer:

the other 60% of energy is stored away for further use in the cell

Explanation:

i hope im right

In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.

How does ATP form from glucose?

Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.

Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.

To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain.  The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .

Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP
