Answer:
The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.
Explanation:
<span>Correct matches: chemicals with their descriptions.
1. abscisic acid ( is the hormone that regulates survival functions of a plant, such as the opening and closing of stomata)
2. auxins (chemicals produced in plants that are characterized by their ability to induce cell elongation and cell division in stems)
3. cytokinins (chemicals that helps plant cells divide)</span>
<span>4. ethylene (a hormone that promotes ripening of fruit or blooming of flowers) </span>
<span>5. gibberellins (chemicals produced by plants that stimulate stem elongation, seed germination, and flowering) </span>
Answer:
Both A and B
Explanation:
Burning fossil fuels produces carbon dioxide.
Cellular respiration produces carbon dioxide.
Both produce carbon dioxide.
Both A and B.
I believe that glyceraldehyde-3-phosphate (G3P) is a product of the Calvin cycle that is used to form glucose phosphate amino acids or fatty acids.
The Calvin cycle is divided into ; carbon fixation, reduction and regeneration of the starting molecule. Energy from ATP and from the reduced coenzyme NADPH is used to remove a phosphate group from 3PGA and reduce the resulting diphosphoglycerate (DPGA) to produce the 3-carbon sugar glyceraladehyde-3-phosphate (G3P).
