Answer:
Cells in Xylem - tracheids and vessel members
Cells in Phloem - the sieve elements, the parenchyma cells, and the sclerenchyma cells
Explanation:
Vascular cylinder is a central column made up of vascular tissue of plant and is also surrounded by parenchymal ground tissue.
The vascular tissue is made up of xylem and phloem tissue. Xylem is made up of two cells tracheids and vessel members and Phloem is made up of three cells namely - the sieve elements, the parenchyma cells, and the sclerenchyma cells
Answer:
C. endonuclease
Explanation:
Endonuclease is a type of enzyme which involves the use of its properties to cleave the phosphodiester bond which are available in a polynucleotide chain such as DNA or RNA.
This enzyme cuts the pre-mRNA between the AAUAAA consensus sequence and a GU-rich sequence before translation takes place in a DNA. This explains why the right choice is an Endonuclsease.
The answer will be, maintenance of bone and calcium
Answer:
a. map unit
Explanation:
The map unit is the unit to represent the chances or the frequency of the recombination between the two genes. It shows the distance between the two genes present on the same chromosome. The frequency of recombination between two genes present on the same chromosome represents the distance between them that is measured in the form of map units. For example, two genes are said to be 10 map units apart if they exhibit 10% recombination. These genes are mapped 10 centimorgans apart from each other on the chromosome.
