Answer:
C- active transport
Explanation:
Because energy is required in this process, it is known as 'active' transport. Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. Active transport often takes place in the internal lining of the small intestine.
Answer: C. Active transport. In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement. Please mark brainliest!

How do the molecular formulas for all the amino acids differ?
The molecular formulas for all the amino acids differ - the R group or side chain.
Each amino acid has the same molecular structure with a central carbon atom, the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Each amino acid is exactly the same except for the R group. little side chain represented by the will be different depending on the kind of amino acid.For example, glycine has a hydrogen atom as its R group, whereas alanine has a methyl group (CH3).Thus, the molecular formulas for all the amino acids differ - the R group or side chain.

How does the use of wild-life/animals impact on the earth?
Answer:
Hope it helps...
Explanation:
Animals help us to save our environment. Some micro organisms such as bacteria help us clean the environment; others help plants by converting free nitrogen from air and feeding the roots. Some insects and earthworms help in agriculture by increasing fertility of the soil and also by increasing organic quality of soil.
Answer:
When a predator goes extinct, all of its prey is released from that predation pressure, and they may have big impacts on ecosystems. If there are too many deer, for example, they can really change the ecosystem because they can destroy forests, and they also carry diseases.

Water molecules can stick to other water molecules through which type of
bond?
Covalent
lonic
Oxygen
Hydrogen
Answer:
Hydrogen Bonds
Explanation:
Hydrogen bonds allow for hydrogens to bond to each other. They are the strongest type of intermolecular bonds.
Hydrogen bonds are dipole-dipole, and when water molecules are close to each other, the hydrogen bonds form between the hydrogen atoms.
Answer:
hydrogen bonds
Explanation:
this type of bond allows hydrogen atoms to bond together.
what is europhication
Answer:
Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake.

compared to the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are
Answer:
Betelgeuse
b.Polaris
c. Aldebran
d.Sirius
e. The Sun
Explanation:
arent sure
In comparison with the surface temperature and luminosity of massive stars in the main sequence, the smaller stars in the main sequence are: cooler and less luminous.
A star is a giant astronomical or celestial object that contains a luminous sphere of plasma and bounded together by its own gravitational force.
Generally, a star typically comprises two (2) main hot gases and these are:
I. Hydrogen (H).
II. Helium (He).
Main sequence refer to stars that can fuse hydrogen atoms in its core, to form helium atoms.
Some examples of a main sequence include the following;
Sun (closest to planet Earth). Antares. Canopus. Vega. Betelgeus.The luminosity of a star can be defined as the total amount of light radiated by the star per second. Also, it is measured in Watts (W).
In conclusion, smaller stars in the main sequence are cooler and less luminous than massive stars in the main sequence.

It was practiced hundreds of years ago by scientists who believed that with the right amounts of heat or chemical reactions, they could make gold. After years of experiments and observations, gold was never produced. Which best describes the practice of alchemy? Alchemy was scientific, because scientists practiced it. Alchemy was scientific, because it included observations and experiments. Alchemy was pseudoscientific, because beliefs came before any observations of success. Alchemy was pseudoscientific, because some successful experiments inspired others.
Answer:
Alchemy was scientific, because it included observations and experiments
Explanation:
Scientific research is one that is done through a series not steps or methods. Observation and experiments are part of the steps in a scientific research.
Scientific research is done through investigation of various theories of science as well as formulating hypothesis. Scientists do not just resort to picking random answers concerning the phenomenons around us. They carry out investigations, observations, and would also formulate potential explanations for what is on ground, carry out experiments and then analyze their results to know if they are right or wrong.
Since the question says observation and experiments were done it is scientific
