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.

Work divided by time is the formula for- (W = T)
O Force
Work
Power
Energy
Answers
Answer:
Power
Explanation:
The formula work divided by time is the expression for finding the power consumed or expended by a body.
Power is defined as the rate at which work is done.
Power = [tex]\frac{work done}{time taken}[/tex]
The unit is always expressed in watts and symbolized as W
Work done is force applied to move a body through a certain distance.
Oxygen-poor blood flows out of the heart and into the lungs. Nutrients and oxygen are sent to other cells and parts of the body. The blood then returns to the heart to begin the process again. Which of the body's systems is the above process describing? Answers (A) -The skeletal system (B)-The digestive system (C)-The respiratory system (D)-The circulatory system
Answers
Answer:
(D)-The circulatory system
Explanation:
lol just did it
and pls give me thanks
The circulatory system is the system which consist of blood vessels, heart, and blood. The main function of this system is the transport of oxygen and minerals to all the cells of body. Thus, the correct option is D.
What is Circulatory System?The circulatory system of body consists of all the blood vessels, blood and heart. In this system, blood travels through different blood vessels (arteries, veins, and capillaries) in all parts of the body.
The blood is the main fluid of the body that contains hemoglobin protein which is responsible for the transport of oxygen and carbon dioxide in the body. The blood exchanges gases at the surface of alveoli in the lungs and sends the blood to the heart, heart pumps the blood to all the cells of body.
Therefore, the correct option is D.

If energy is released, free energy must be what?
Answers
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

Answer: Okay so Photosythesis is the process used in most plants (except carnivorus plants) when the plant uses its chroloplasts (cells only plants have) to convert sunlight into sugar which makes food for the plant so it can live without having to hunt for food.
Explanation:
I hope this helps sorry if it doesn't :(
Have a good day :)
Stay motivated :)
Answer:
Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?
A.silent
B.missense
C.nonsense
D.insertion
Answers
Answer:
A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.
Explanation:
In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.
In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.
For the other options:
Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.Answer:
Silent
