Can someone help me i got very confused

Answer:

no

Explanation:

you have to have the right amount and the right situation for it to turn into water. for instance The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.

Answer:

C. Charged, polar, or non-polar

Explanation:

Amino side chains, also called R groups, are classified into the categories of charged, polar, and non polar.

These classifications can be determined by the structure and elements within the R group/functional group.

inorganic compounds:

-usually lack carbon

-are not associated with or made from living things

organic compounds:

-contain carbon and other elements

-are found in organisms

i just learned this!! i hope it helps.

:)

Explanation:

The main difference between the two classes of substances is that organic compounds always contain the element carbon, while most inorganic compounds lack this element.

example of organic compound is methane, CH4

example of inorganic compound is, argon Ar

Answer:

The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can't escape bias. It results from personal beliefs, as well as cultural beliefs, which means any human filters information based on his or her own experience. Unfortunately, this filtering process can cause a scientist to prefer one outcome over another. For someone trying to solve a problem around the house, succumbing to these kinds of biases is not such a big deal. But in the scientific community, where results have to be reviewed and duplicated, bias must be avoided at all costs.

­T­hat's the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions. Even with such a rigorous methodology in place, some scientists still make mistakes. For example, they can mistake a hypothesis for an explanation of a phenomenon without performing experiments. Or they can fail to accurately account for errors, such as measurement errors. Or they can ignore data that does not support the hypothesis.

Answer:

Yes, because the question is specific.

Explanation:

The given question is scientific because it comprise of logic and reasoning, this question only be answered after performing experiments in the laboratory in order to find the factor behind the change of color. The question is specific because it only occurs in hare and we have to know that this change in color occurs due to change in temperature of the environment or not. So we have to perform scientific investigation.

Answer:

Answer is A

Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .

Most of the mass of an atom is concentrated at the center of the nucleus.

Atoms are made up of three subatomic particles called

1. Protons

2. Neurons

3. Electrons

protons - has positively charge particles with a charge

of +1

Neutrons- has no charge it is neutral, 0 charge.

Electrons- has a negative charge particles with an charge of -1.

Relative mass of a particle is the mass compared to the mass of a proton

Relative charge of a particle is the charge compared to the charge on a proton.

Atom is a basic unit of matter have proton and neutron containing nucleus at the center and surrounding electrons.  

Atoms are the smallest and basic units of  matter.

A negatively charged electron which surround the nucleus of the atom moving around the orbitals or energy levels.  

The nucleus does not change during chemical reactions, only in nuclear reactions it will change.

In nucleus equal number of protons and neutrons, atomic number is the number of protons and atomic mass is made of the sum of protons and neutrons.

Relative mass of a matter is the  mass of a proton while Relative charge of a matter is the charge on a proton.

Answer:

A) the origin of eukaryotes

Explanation:

The Endosymbiotic theory talks about how the ancestors of modern eukaryotic cells were once 2+ prokaryotic cells. This theory says that one prokaryotic cell basically lived inside another prokaryotic cell and these cells formed a long term relationship. The prokaryotic cell eventually became a permanent part of the host and eventually evolved into modern day eukaryotic cells.

The Endosymbiotic Theory explains the origin of eukaryotes.

The endosymbiotic theory posits that some eukaryotic cell organelles, such as mitochondria and plastids, evolved from free-living prokaryotes.

The most significant examples of endosymbiosis are represented by the endosymbiotic acquisition of plastids and mitochondria, introducing photosynthesis and respiration to eukaryotes.

Eukaryotic cells may have evolved when multiple cells joined together into one. They began to live in what we call symbiotic relationships. The theory that explains how this could have happened is called endosymbiotic theory.

Answer:

Animals tissues are grouped into four basic types: connective, muscle, nervous, and epithelial. ... It serves functions of protection, secretion, and absorption, and is separated from other tissues below by a basal lamina.

Answer:

In animals there are four types of tissues. Their functions are::

1. Epithelial tissue: covers body surfaces ,line the body cavities ducts and glands.

2. Connective tissue: support the body and binds body organ together and stores the fat.

3. Muscular tissue: contraction and movement

4. Nervous tissue: transmit nerve impulse that coordinate body activities.

Answer:

Answer: Perpendicular

Explanation:

Joint movement: This is a movement which occurs around an axis that is always perpendicular to its plane. This can also be defined a movement which usually occurs or happens in a plane and around an axis. perpendicular is used to describe the meeting angle which is usually ( 90 degrees) to the ground.

Answer:

presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits

in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance

sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them

the sugar dissolves in water, creating a sugar solution

this results in fruits with less water inside them, and surrounded by sugar solution
