Answer:

The correct answer is A) differentiated cells retain all the genes of the zygote

Explanation:

A plant can be cloned from the somatic cells which shows that the differentiated cell of plants have the ability to divide and differentiate to produce a new plant. This property of the cell is called totipotency.

All the cells in plants are not totipotent but some cells under proper condition can show the property of totipotency. Totipotency property shows that the differentiated cell is having all the genes that were present in the zygote.

This property of plant cells is used by scientist in plant tissue culture to produce plants for research and other purposes. So the right answer is A.

worty [1.4K]

Answer:

The 5' end has free phosphate group while the 3' end has free OH group.

Explanation:

Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.

A caregiver of a toddler has called the poison control nurse to report that the child licked a small amount of petroleum jelly.
mel-nik [20]
The correct answer is to "dilute with milk and water". The patient should not be induced to vomit to prevent aspiration as this can lead to another condition which is aspiration pneumonia. The patient should be given either a glass of milk or a glass of water for ingestion of petroleum jelly.
