Differentiate betweeli population density and
population distribution.
Answer:
The main difference between population density and population distribution is that the population density is the number of individuals per unit land whereas the population distribution is the spreading of people over an area of land. Furthermore, population density is unable to describe where the population actually lives, unlike population distribution.
Population density and population distribution are two measurements of population used in a variety of applications in ecology.

What gives a protein its unique shape?
Question 5 options:
neither
the unique sequence of amino acids in its polypeptide chain
the unique folding of the polypeptide chain
Answer:
the unique sequence of amino acids in its polypeptide chain
Explanation:
Protein is a large molecule which is made from a chain of smaller molecules called amino acids. There are twenty amino acids exist, and when they bond together they make unique proteins depending on their sequence in the chain.
How is the plasma membrane of a cell like dialysis tubing?
Like a cell membrane, dialysis tubing has a semi-permeable membrane, which allows small molecule to permeate through the membrane. Thus, the dialysis tubing mimics the diffusion and osmosis processes of the cell membrane (Alberts, 2002). ... Instead, facilitated diffusion would be needed to transport the glucose.

Write down the tRNA anti-codons that pair with the mRNA strand.
Note: Please use capital letters, and follow this format: A-A-A-A-A-A-A-A
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.

Which pH indicates a basic solution?
1.
1
2.
5
3.
7
4.
12
Answer:
7
A pH value greater than 7 indicates a basic solution. The more the pH value exceeds 7, the more basic is the solution.
7 is the answer.
If the pH is 1, that means the substance is sour or acidic.
If it has a pH of 5, then it is not that acidic.
If something has a pH of 12, then it is almost completely basic.
If something has a pH of 7, then it is basic.

Which of the following is an indicator of good water quality? (2 points)
Answer→ Physico-chemical indicators
Explanation ≈ They include dissolved oxygen, pH, temperature, salinity and nutrients (nitrogen and phosphorus). They also include measures of toxicants such as insecticides, herbicides and metals.
Sort the phrases based on whether they represent kinetic energy or potential energy.
Answer: The main difference between potential and kinetic energy is that one is the energy of what can be and one is the energy of what is. In other words, potential energy is stationary, with stored energy to be released; kinetic energy is energy in motion, actively using energy for movement
Explanation:

HELPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
In the cells of humans and other animals, a great deal of energy is dedicated to operating a pump that transports sodium (Na+) ions out of cells and potassium (K+) ions into cells. This transport creates a chemical and electrical gradient. Maintaining the proper balance of sodium and potassium is critical to ensuring that nerve cells work properly. Nerve cells drive muscle contractions—including heart muscles—and are responsible for animals’ abilities to sense their environment and for humans’ ability to think.
Scientists gain a better understanding of the sodium-potassium pump by creating models of what the pump accomplishes. Such models are used to examine many other complex processes as well.
This model of the sodium-potassium pump illustrates the process by which sodium is pumped out of cells and potassium is pumped in. The sodium-potassium pump moves the two different ions in opposite directions.
Where in a cell does this transport process take place?
A.
nucleus
B.
cell wall
C.
cell membrane
D.
vesicle
The Transport process takes place in cell membrane.
What is Transport?Cell transport describes the transportation of a material across a cell membrane. The chemical has the ability to enter or exit cells.
The plasma membrane and cell membrane are both permeable to different substances. The nature of the plasma membrane is quite selective.
Cell transport is very important for transport of molecules. There are two transport of cell transport of endocytosis and exocytosis.
Therefore, The Transport process takes place in cell membrane.

What gases was not present in earths earth atmosphere
Answer:
Primitive Earth (Before life) contained no or very little Oxygen (element#8)
According to scientific theory:
Earth had no oxygen to begin with. It had a lot of carbon dioxide, though. Somehow (We still do not know how they started growing) single-celled Carbon Dioxide-breathing bacteria slowly, over thousands to millions of years, turned most carbon dioxide into oxygen, supporting new types of life.

Where are electrons located?
Answer: they rotate the nucleus creating the "outer casing" that you see in diagrams
Explanation:
What subatomic particles are found on the inside of an atom (the nucleus) and what subatomic particles are found on the outside (in the rings)?
Answer:
In the nucleus of an atom, we find 2 subatomic particles, protons, and neutrons.
On the outside, on the rings, are electrons.
