Answer:

d. The density of a substance is always the same, regardless of temperature.

Explanation:

Density is a characteristic property of water and defined as the mass per unit volume.

The density of a substance always remains the same at the same temperature regardless of the size of the sample. The density of the sample changes with temperature and pressure. for example : The density of a substance increases with a decrease in temperature as the volume increases.

Hence, the statement about density is not true is " d. The density of a substance is always the same, regardless of temperature."

When gaseous state changes into liquid state the molecules slow down in speed because of decrease in energy molecules come slightly closer to each other.

Answer:

A

Explanation:

Animals take in oxygen and convert it into carbon dioxide therefore the oxygen levels will decrease and the carbon dioxide levels will increase

If an animal is placed into a sealed container for a short time, the oxygen level will:  decrease and the carbon dioxide level will increase.

The oxygen held inside the space is quickly being consumed by the freight or because of rusting inside a space, and that encased spaces must consistently be treated as perilous. And the carbon dioxide levels on the other hand will increase.

It will not take a long time for an animal to survive under these conditions.

Thus. option A is correct.

Explanation  b  The motion of the particles increases and the distance between the particles decreases.

The motion of the particles decreases and the distance between the particles increases, the correct option is C.

The matter is anything that has mass and occupies space.

Matter can exist in four different states: solid, liquid, gas, and plasma.

By examining the arrangement of molecules, it is possible to comprehend the characteristics of the many forms of matter.

The state of a solid turns to a liquid when it is heated past its melting point.

A liquid turns into a gas when it is heated past the point at which it vaporizes.

Solids have a distinct shape and dimension and are densely packed.

Liquids fill the container's space and are loosely packed.

Gas has a large intermolecular distance and is not stiff.

When energy is removed from the particles of a liquid, the speed gets slowed, and so the motion decreases, as the motion is limited they become packed and the distance between them decreases, and the intermolecular forces increases.

Answer:

The experimental plan is to measure the values of the dependent variable, which is the temperature of the pizza after it is cooled in each of the heat (temperature) environments, which is the dependent variable, for a given equal period of time, which is the control

Explanation:

The given parameters are;

The temperature of the pizza = 400°F

The temperature of the freezer = 0°F

The temperature of the refrigerator = 40°F

The temperature of the countertop = 78°F

Given that the independent variable = The heat to which the hot pizza is subjected

The dependent variable = The temperature to which the pizza cools down

The experiment plan includes;

1) Place the pizza which is at 400°F in each of the different heat environment, which are, the freezer, the fridge, and the counter top, for the same period of time and record the final temperature of the pizza

2) The option that gives the lowest final temperature within the same time frame is the option that will let the pizza cool down fastest.

ABOUT HYPOXEMIA -: It is called hypoxemia to have low oxygen levels in your blood. It is called hypoxia to have insufficient oxygen levels in the tissues. Hypoxemia at high altitudes can occur. Hypoxemia that induces low levels of oxygen in the tissues of the body is called hypoxia. The two words are often used by people interchangeably, but they are not the same thing.

The capacity of the body to supply normal amounts of oxygen to the blood can interfere with a number of conditions and circumstances. Some of hypoxemia's most prevalent causes include:

Answer:

In order for her body to act correctly, Lucille's cells require glucose and oxygen.

A problem with Lucille's respiratory system leading to low levels of oxygen in her cells is known as Hypoxemia.

Having low levels of oxygen in her cells will make it difficult for Lucille to play soccer because she would not be able to breathe .If her respiratory system doesn't function properly, so enough oxygen molecules will not move into her respiratory system , ensuring that her cells won't have enough oxygen molecules. Playing soccer is difficult if you don't have enough air.

Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release.

During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.

Answer:

The correct option is;

CO₂

Explanation:

The given information are;

The number of molecules in the substance = 1.3 × 10²⁵

The mass of the substance = 968 g

Therefore, we have;

The number of molecules in one mole of a substance = 6.02 × 10²³

The number of moles present = (1.3 × 10²⁵)/(6.02 × 10²³) ≈ 21.595 moles

Therefore, 968 g = 21.595 moles

1 mole = 968/21.595 = 44.826 g

The mass of one mole of the substance = 44.826 g

Therefore the mass of one mole of the substance is closely related to the mass of one mole of CO₂ which is 44.01 g/mol.  

The correct option is CO₂

The number of molecules in one mole of a substance should be = 6.02 × 10²³

And,

The number of moles present is

= (1.3 × 10²⁵)/(6.02 × 10²³)

≈ 21.595 moles

Now

1 mole = 968/21.595 = 44.826 g

The mass of one mole of the substance = 44.826 g

So,  the mass of one mole of the substance is closely related to the mass of one mole of CO₂ i.e.  44.01 g/mol.

Answer:

The egg is the dependent variable and the salt is the independent variable.

Explanation:

The dependent variable is something that stays the same throughout the experiment. The independent variable is something that might not stay the same throughout the experiment. The egg does not change because we're using an egg and not an egg and then a tomato or a potato, but the salt does change because we're changing the amount of salt in the bowl/plate or anything else that we are using to perform this.

Answer:

each principal energy level above the second contains, in addition to one s orbital and three p orbitals, a set of five d orbitals, called the d sublevel. The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.

Answer:

It is secondary succession.

Explanation:

primary succession only occurs in areas where there was no previous ecosystem

In the production of maple forest over the 1,000 years period, there has been the presence of the lake. Thus the production in the lake has been the secondary succession.

The primary and secondary succession has been the development process in the ecosystem. The ecosystem development can be taken place when there has been no previous vegetation, or when there has been the available ecosystem.

The primary succession can result when there has been no available previous ecosystem. The secondary succession can take place when there has been a previously existing ecosystem.

In the production of maple forest over the 1,000 years period, there has been the presence of the lake. Thus the production in the lake has been the secondary succession.
