Answer:
CRISPR can also be used to make precise changes such as replacing faulty genes – true genome editing – but this is far more difficult. Customised Cas proteins have been created that do not cut DNA or alter it in any way, but merely turn genes on or off: CRISPRa and CRISPRi respectively.

What is the cell membrane?
A) the center of the cell
B) the boundary of the cell
C) the energy producer of the cell
D) the substance that fills up the cel
Answer:
B is the answer
Explanation:
The cell membrane is the boundary of the cell, separating the cell material from the outside environment, hence option B is correct.
What is the function of the cell membrane?All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move compounds out of the cell that is harmful as well as nutrients into the cell.
Therefore, the cell membrane is the boundary of the cell.

What are mutations, and how can they affect proteins? pleaseeeee helppp
A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition

Carbon dioxide is used by plankton during photosynthesis to make organic molecules containing ( lead / carbon / argon / chlorine )
Answer:
Carbon
Explanation:
Photosynthesis is a process carried out by the cells of autotrophic organisms in order to synthesize their own food in form of sugars (glucose). As rightly stated in this question, Carbon dioxide (CO2) is a major ingredient for this process to occur. Inorganic CO2 enters an organism like plankton and is used to make organic molecules.
The organic molecules produced via the photosynthetic process are in form of sugar (glucose) i.e. C6H12O6 whose principal elemental component is CARBON. In other words, the organic molecules contain carbon in their structure, got from the CO2 source.

After the enzyme and substrate bind together and perform the reaction, what does the substrate become?
Answer:
When an enzyme binds its substrate, it forms an enzyme-substrate complex. This complex lowers the activation energy of the reaction and promotes its rapid progression by providing certain ions or chemical groups that actually form covalent bonds with molecules as a necessary step of the reaction process.
After the enzyme and substrate bind together and perform the reaction, the substrate becomes a PRODUCT of that chemical reaction.
Enzymes are biological catalysts that bind specific substrates to speed up the rate of a given chemical reaction. Substrates are molecules upon which the enzymes act.Products are molecules formed from chemical reactions.Enzymes function by lowering the energy of activation of different chemical reactions.In conclusion, after the enzyme and substrate bind together and perform the reaction, the substrate becomes a PRODUCT of that chemical reaction.

When a person eats the yogurt, the 14 grams of protein will be A combined into monosaccharides. B combined into polysaccharides. C broken down into amino acids. D broken down into nucleic acids.
Answer:
C broken down into amino acids.
Explanation:
Proteins are one of the four major biological molecules. They are organic polymers made up of monomers called AMINO ACIDS. Proteins are contained in food we ingest and are subsequently digested or broken down into their amino acid components.
In this case, when a person eats yogurt (containing proteins), the 14 grams of protein will be broken down into amino acids during digestion by enzymes called PROTEASES. Note that every polymer will be broken down into its monomeric constituents during digestion.

What “rule” or reasoning did you use to decide if something is a rock?
Answer: Anything that has an Origin, composition, and texture.
Explanation:
May be Minerals, feel rough or smooth, and can be hundreds or thousands of years old.
A rock is a naturally occurring compound which is made up of one or more minerals. They are found in the Earth's crust which undergoes transformation with the changing environmental conditions.
What qualities define a rock?
A rock can be defined as a solid mass of geological materials. The geological materials include individual mineral crystals, inorganic non-mineral solids such as glass, pieces broken from other types of rocks, and even the fossils.
The physical properties of rock include density, porosity, and permeability, etc. The mechanical properties of rock mainly include the elastic modulus, Poisson's ratio, and its strength. These parameters can be obtained through the laboratory experiments of core samples or by the in-situ tests.

6. Study the beaker and its content in the diagram below. in what direction 2 points
most of the water would flow into the "sac" or out of the "sac". Explain
why and name the type of solution being illustrated.
Answer:
The correct answer is -
1. into the sac
2. in beaker hypotonic, in sac hypertonic
Explanation:
Osmosis is the diffusion of the solvent of a solution to the higher solute concentration through the semipermeable membrane. This membrane allows the water or solvent movement from the low solute concentration to high solute concentration and makes the cell or the sac bloated or turgid.
In this case, 2% slat concentration is dissolved in water which has low solute concentration in comparison of the sac which has 10% solute concentration so the outside the sac hypotonic solution present which allows the solvent to move from outside into the sac.
