Answer:
Root hair cells
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption

prevent bronchospasm in people with reversible obstructive airway disease. It
is also used to prevent exercise-induced bronchospasm.
Answer:
The answer is A or number 1
Explanation:
Answer:
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Explanation:
Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.
