Answer:
a. yes
b. high concentration.
Explanation:
Yes, molecule move from high concentration to low concentration by the process of diffusion.
What is diffusion?
Diffusion is a process or movement of molecules where they move from high concentration to low concentration. It is a passive movement. Molecules move downhill from their concentration gradient.
Since, for transfer of this molecules no energy is required it is called passive transport. In plants diffusion is a important process for transfer of gases.
In animals, it plays a important role for transfer of gases such as oxygen and carbon dioxide. If we bring cheesy pizza into the classroom then the aroma of the molecules move down the concentration gradient.
Therefore, Yes, molecule move from high concentration to low concentration by the process of diffusion.

Which is the MOST accurate description about how the different types of feed mechanisms work.
A. Both positive and negative feedback loops amplify a departure from the set point.
B. Both to negative and positive feedback loop returns to the set point in the reverse direction
C. Positive feedback loops return to the set point in reverse direction, why negative feedback loops amplify the departure from this point.
D. Negative feedback loops return to the set point in reverse,wow positive feedback loops amplify a departure from the set point
Answer:
D
Explanation:
Positive feedback loops are rarer than negative ones because of homeostasis, but they do occur. Negative feedback loops return to the set point in reverse, and positive feedback loops amplify a departure from the set point.

What are so tiny that they are measured at only a few thousand light-years or less and astronomers think that there may be billions of them in our universe?
Answer:
The correct answer is STARS
Explanation:
Billions of stars are believed to be in different galaxies and a lot more billions are believed to be in our universe. These stars are small/tiny that they are a few thousand light-years away. Light-year is the unit for measuring distance of bodies in space which can be described as how far a beam of light travels in a year.

The central atom in an amino acid that all the groups connect to is a
O A. Hydrogen
.
O B. Oxygen
• O C. Carbon
.
O D. Nitrogen
Answer:
C. Carbon
Explanation:
The central atom in an amino acid that all the groups connect to is a carbon atom.
Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.
This is common to all amino-acids.
can a cell can survive even if the process to produce ATP is disrupted?
Answer:
No, because ATP provides energy for cells in order for them to carry out their functions. If disrupted it will cause the transport chain to stop which causes ATP to stop and the cells can no longer carry out their functions and will die.

the half-cooked egg yolk oozes out only when it is still hot.In the same manner,the magma on the mantle also rises because of high temperature, in the mantle, or the crust?
Answer:
the mantle
Explanation:
The correct answer would be the mantle.
The magma is a hot, molten fluid or semi-fluid located beneath the earth's surface and capable of finding its way through fissures into the surface of the earth in a process known as a volcanic eruption.
From the innermost to the outermost, the earth layer consists of the inner core, the core, the mantle, and the crust. More specifically, the magma is known to originate from the lower part of the crust and the upper part of the mantle. The mantle's temperature is high and forms a layer of partially molten rock.

Molecules of an element
Molecules of a compound
Atoms of a compound
A mixture
Answer:
B
Explanation:
i took the test
The correct option is (B). Molecules of a compound.
What do you mean by molecules?A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Moreover, molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
Hence, the smallest particle of any substance which can exist independently and retain the physical and chemical properties of the substance, made up of one or different elements is a molecule.

The study of a living being is called biology.
The correct answer is B.
The process of conversion of a large molecule into a smaller molecule with the help of an enzyme is called digestion. The enzyme converts the organic and complex molecules to the simpler molecule which helps in absorption and later on is used up to form ATP.
According to the question, the larger molecule which is an organic molecule is breakdown into smaller molecules.
