The answer is A, bacteria can move around, use energy, and reproduce just like humans can, the only difference is they're single cell and we're not.
Answer:
Hurricanes will become more frequent and expand to new areas.
Explanation:
Global warming will rise sea temperatures worldwide. This means conditions for hurricanes will be met more often (they only form in higher than average sea temperatures). That means more hurricanes will form in the future. Also because of rising sea temperatures new areas will be effected by hurricanes as they will meet the threshold required for hurricanes to form.
Pheromones used in reproduction are not likely to be found in organisms that only reproduce asexually.
The chemicals called pheromones are used to communicate between members of the same species and cause the recipient to react physically or behaviorally. Pheromones are a subset of organisms' larger class of chemicals to communicate, known as semiochemicals, from the Greek <em>semeon</em>, meaning signal or mark.
Animals communicate chemically constantly, with pheromones mediating more interactions than any other type of signal. The majority of pheromone research has been conducted on insects, particularly species that are considered pests.
For these, using pheromones that alter their behaviour in various ways might be employed for population control, pest management, or monitoring.

Answer: By losing its two outermost electron
Explanation:
Calcium is a element that belongs to group 2 in the periodic table. It has an atomic number of 20, and an electronic configuration of 2, 8, 8, 2.
Hence, to form an octet structure, it gives off its two electrons as shown below:
Ca <----> Ca2+ + 2e-
Thus, by losing its two outermost electrons, a positively charged calcium ion (Ca2+) is formed
