Answer:
a. 500
Explanation:
The effective size of a given population is calculated by simply counting the total amount of organisms that actually are in conditions of reproduce and produce certain offspring in the next generation. In this particular case, althugh the population is formed by a total of 1000 individuals, only 500 organisms are capable of reproduce at that particular instant, and therefore contribute with offspring to the next generation.
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata . ... These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
Answer:
D) Three of the reaction steps in gluconeogenesis would have prohibitively large, positive free energies if they used glycolytic enzymes for their catalysis.
Explanation:
The glycolytic enzymes catalyze the conversion of glucose to pyruvate, while gluconeogenesis enzymes catalyze the formation of carbohydrates from pyruvate.

Answer is Translational control.
Gene expression refers to genes being ‘turned on’ and makes protein as product. Protein can be a structural protein, an enzyme or a control molecule. The protein synthesis rate is proportional to the concentration and translational efficiency of its mRNA. Translational control governs the efficiency of mRNA production. Translational control mechanisms are the most determining for final protein levels.
