In a _______ mixture, the ingredients are distributed evenly throughout the mixture, while in a _______ mixture, the ingredients are unevenly distributed throughout.heterogeneous; homogeneous
heterozygous; homozygous
homozygous; heterozygous
homogeneous; heterogeneous

Answers

Answer 1
Answer: In a homogeneous mixture, the ingredients are distributed evenly throughout the mixture, while in a heterogeneous mixture, the ingredients are unevenly distributed.

The correct answer choice is the fourth one. You know this because you can eliminate the second and third choices since homozygous and heterozygous are terms more commonly used in genetics. And you can eliminate the first one because a homogenous mixture is more like a solution, where it is blended to where it looks like one substance. For example, pudding would be a homogenous mixture. So, homogeneous has to be in the first blank.
Answer 2
Answer:

Answer:

homogeneous; heterogeneous

Can a tank of oxygen gas ever be half empty? explain

Answers

No, it is practically very unlikely situation. Oxygen is a gas and gas has no shape it occupies the shape of the container. moreover, according to the kinetic theory of gases, the particles of gas move in random motion occuping the space. The particles move randomly and keep on colliding with each other. Therefore, it is not correct to say that a tank of oxygen gas can ever be half empty.
The answer is yes. The compacted air moves to the sifter bed channels. The strainer bed channel assumes an imperative part, as the gadget expels the nitrogen from the air. After air is first compacted in the concentrator, it is constrained into the primary strainer bed. Oxygen is sent into the item tank.

Which subatomic particle makes the atoms of each elements different?

Answers

The subatomic particle that makes the atoms of each element different are the protons. The specific number of protons for a particular element distinguishes one element to another.

A visible streak of light that shows the path of a rocky object which has entered Earth’s atmosphere is

Answers

Answer:

A visible streak of light that shows the path of a rocky object which has entered Earth’s atmosphere is Meteor.

Explanation:

Meteors are the dust and ice originated from the trails of comets. They are the rocks present in the space, the visible bright streak is not from the rock, rather from the glowing hot air because of the hot rock zips from the atmosphere. When large number of the meteoroids strikes the Earth at one time is called meteor shower. It is the open- source isomorphic rocks. These are visible from the one point in the dark sky. These happens due to the masses of cosmic debris known as meteoroids which are coming inside the Earth's atmosphere at extremely great speed on parallel trajectories.    

How do the particles that are dispersed in a colloid differ from the particles suspended in a suspension?The colloid particles are less dense.

The colloid particles are more solid.

The colloid particles are smaller.

The colloid particles are larger.

Answers

Answer: The correct option is that the colloid particles are smaller.

Explanation: There are 3 types of solutions:

1) True solutions: These are the solutions in which the size of the particles are less than 1nm. These are considered as homogeneous mixtures.

2) Colloids: These solutions are the solutions in which the size of the particles lie in the range of 100nm to 1nm. These are assumed to be homogeneous mixtures but actually are heterogeneous mixtures.

3) Suspension: These solutions are the solutions in which the size of the particles are greater than 100 nm. These are considered as homogeneous mixtures.

The particles which are dispersed in a colloid have smaller particles than the particles which are dispersed in a suspension.
