Seeds have cotyledons from where they can draw their nutrient in their early stages of development. Pollens must draw their nutrient from their environment from the start. Seeds have an outer coating (testa) that protects the embryo and enable it to remain dormant in the soil until right conditions for growth set forth Seeds have a fully developed embryo that can begin to grow immediately there are right conditions. However, pollen has a single cell instead of an embryo, which must undertake cell division and specialization before beginning to germinate

pochemuha

Answer:

using energy released from breaking high-energy covalent bonds in organic molecules to force ATP formation from ADP and phosphate.

Explanation:

The cellular respiration involves the generation of energy for bodily activities. This is technically known as the Kreb's Cycle or citric acid cycle. This is the process through which the intracellular metabolism of glucose takes place. Specialized organelles, called mitochondria are responsible for the process. The organelles ensure that the breaking of the high energy phosphate bonds in the ATP monocle generate energy. Overally, the process is a hydrolysis process. This involves the movement of the hydrogen ions an the generation of 38 high energy phosphate bond breakages.

If you were to observe the activity of methylated dna, you would expect it to _____.

stiv31 [10]

If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.

<h3>What is the activity of methylated DNA?</h3>

DNA methylation is a process by which methyl is added to the DNA molecule which can change the activity of a DNA without changing the sequence. When it is located in a gene promoter, DNA methylation acts to repress gene transcription.

So we can conclude that If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
