Answer:
Deoxyribonucleic acid (DNA)
Answer:
Statements 1, 2 and 4 are correct:
"Hormones can be peptides, steroids, or amino acid derivatives."
"Hormones can stimulate the synthesis of target proteins through the activation of specific genes."
"Hormones can increase the cellular uptake of metabolites."
Explanation:
Hormones are basically proteins that are released under particular conditions to bring about a certain response in the body. They can activate genes and even change how cells respond to metabolites, for instance, insulin and glucagon are two hormones that regulate the level of sugar in the blood. Another example is the hormone adrenaline, which is released in the 'flight-or-fight' response to prepare the body in taking action.
Hope that answers the question, have a great day!
Answer: 2.6 x 10^13 m/day
Work:
There’s 86,490 sec per day, so
(3.0 x 10^8 m/s)(86,400 s/1 day) = 2.6 x 10^13 m/day
Step 1: Imbibition water fills the seed.
Step 2: The water activates enzymes that begin the plant's growth.
Step 3: The seed grows a root to access water underground.
Step 4: The seed grows shoots that grow towards the sun.
Step 5: The shoots grow leaves and begin photmorphogenesis.
