<u>B. Secondary xylem</u> tissue makes up most of the wood of a tree.
<h3><u>What exactly is secondary xylem?</u></h3>
Secondary xylem is a sort of xylem produced by secondary growth. During initial growth, in contrast, the primary xylem develops. As a result, the secondary xylem is linked to the primary xylem by lateral growth as opposed to the vertical extension.
The kind of cambium that gives rise to each difference is another point of differentiation. The vascular cambium produces the secondary xylem, while the procambium produces the primary xylem.
Unlike trees and shrubs, non-woody plants lack secondary xylem. It gives such plants mechanical support by depositing lignin into their cell walls, thickening them. Compared to the major xylem, the secondary xylem is made up of tracheids and veins that are shorter and wider. In comparison to the primary xylem, it is also richer in xylem fibers.
Possible growth rings in the secondary xylem (or annual rings). Sapwood and heartwood are two differentiators of the secondary xylem in big woody plants.

The answer to this question would be: half of
Gametes cell is a haploid cell that only has half of genetic material from the parent cells. The process of making gamete cells is called meiosis.
The gamete is haploid because it was used in fertilization and need to fuse with other gametes(example: sperm with the egg) resulting in a full paired chromosomes.
Answer:
Explanation:
Acid. is a substance that increases the hydrogen ion concentration in a solution.(hight H+ concentrations) ~When hydrochloric acid is added to water, hydrogen ions dissociate from chloride ions: HCl -> H+ + Cl− ~Addition of an acid makes a solution more acidic.
Answer:
The correct answer will be option- B.
Explanation:
The Transduction is the process of the genetic transfer by which the foreign DNA is incorporated in the genome of the cell using virus or bacteriophage. The process of transduction was discovered by the Zinder and Lederberg in 1952 in the species of<em> Salmonella</em> bacteria. The transduction process is of two types: generalized and specialized transduction.
Thus, option- B is the correct answer.
What alleles do the parents have? If the parents are both Homozygous recessive the answer is 0%. If one is homozygous dominant it doesn't matter what the other one is, the answer is 100%. if the are both heterozygous the answer is 75%
