Direct repair is mutation repair that does NOT involve the removing and repairing of nucleotides
A mutation in biology is an adjustment to the nucleic acid sequence of an organism's, virus's, or extrachromosomal DNA. DNA or RNA can be found in the viral genome. Since mutation results in a new DNA sequence for a particular gene, resulting in a new allele, it is crucial as the initial stage of evolution. Through intragenic recombination, recombination can also produce a new DNA sequence (a new allele) for a particular gene.
DNA proofreading and repair systems often identify mutations and mutation repair. The cell will also go through programmed cell death (apoptosis), which prevents the flawed DNA from being passed on if the damage cannot be repaired. Only when these systems are compromised do mutations take place and are transmitted to daughter cells.
What kind of mutation repair does NOT involve the removing and repairing of nucleotides?
a. mismatch repair
b. base-excision repair
c. direct repair
d. None of the above, because all repair involves the removing of mutated nucleotides.

Mangroves are most likely to be found in brackish water. Brackish water is more saltier than freshwater but it doesn't quite reach the level of seawater. Fun fact mangroves are called halophytes.
I think this is answer but i'm not sure it is right or wrong 3+14= 17
Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
Xylem are tubes in the stem that transport water and minerals upward, from the roots to the leaves. Phloem are tubes in the stem that move food made in the leaves to other parts of the plant. ... Chlorophyll is a pigment that helps plants use energy from the sun to produce sugars.
