Answer:
question no 1 answer
A root hair,or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope. They are found only in the region of maturation of the root. Just prior to and during root hair cell development, there is elevated phosphorylase activity. Plants absorb water from the soil by osmosis. Root hair cells are adapted for this by having a large surface area to speed up osmosis. Another adaptation that they have is a large permanent vacuole.
question no 2 answer
Answer: Stems hold the plant upright and support it. They also transport water, minerals and sugars to the leaves and roots.
hope it helps
because i have taken it on by book
<span>Most nutrients absorbed by the small intestine pass to the portal venous system which drains to the liver, where they are processed. Fats (lipids) are passed to the lymphatic system through lymph vessels called lacteals. They are passed from the lymphatic system to the blood circulation via the thoracic duct.</span>
Because it was not tested multiple times by other scientists
Energy can never be created or destroyed, just changed (from one form to another). There shouldn’t be an “or” for the second part bc that’s the only answer.
The right option is; D) It has high-energy phosphate bonds
ATP contains a large amount of energy because it has high-energy phosphate bonds.
Adenosine triphosphate (ATP) is an organic molecule that performs important roles as an energy transport molecule, a phosphate donor, and a signaling molecule within cells. ATP is made up of adenosine (an adenine ring and a ribose sugar), and three phosphate groups. ATP is an unstable molecule which hydrolyzes when it react with water to form ADP (adenosine diphosphate) and inorganic phosphate. The large amount of energy of ATP comes from the two high-energy phosphate bonds.
