Answer:
b. the bond between the phosphate groups is broken to release energy
Explanation:
- Phosphate groups are negatively charged => there is a pull between the two groups
=> it's easy to break this bond & ATP is unstable
=> ATP has a lot of free energy
- breaking the bond between phosphate groups makes the molecules more stable (aka contains less free energy)
=> delta G <0
=> breaking this bond releases energy
- the energy released by ATP is then used to transport large molecules against the concentration gradient
Answer: That answer is completely FALSE

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.

<span>Ans: G1 phase
Explanation:
Preparation of a newborn division happens in three steps:
G1 phase, G2 phase and S phase.
In G1 phase, the cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps.
mitosis is the process in which the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules.</span>
Isotonic because water is going both in and out of the cel
