The answer is A.only autotrophs can convert solar energy into chemical energy.
Answer: Keystone species
Explanation: A keystone species is a species which occupied a niche so central in the ecosystem that it has a disproportionately large effect on its environment and other species in it.
The coral's function in its ecosystem is so vital that if you were to remove it, the entire community would be drastically altered beyond recognition.
The coral serves as the base structure of its ecosystem.
That is to say that many corals are hermatypic(they form reefs). This reef serves as the environmental structure of the Coral's ecosystem. Built in and around it is a very biodiverse biotic environment. The coral not only serves as a hiding place and habitat for many marine organisms including fish, clams, lobsters, etc. It serves as resting place for larger animals like turtles and also serves as hunting sites for other animal species.
The most common way of determining a keystone species, is to see what happens when that species is removed from the ecosystem. Coral have shown to be so central to their ecosystem that the bleaching of coral reefs due to tourism and climate change causes a massive loss to biodiversity. And this is quite significant as reefs are the most biodiverse marine habitats.
Answer:
The correct answer is "I, II, and III".
Explanation:
The missing options of this question are:
I only
II only
III only
I, II, and III
The correct answer is "I, II, and III".
Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:
I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.
II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.
III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.
The answer to this question would be: <span>during pregnancy
Body metabolic rate will be increased during pregnancy because the mother needs to supply the child needs too. In reduced-calorie diet, the body will adapt to the hunger by lowering the basal metabolic rate. The basal metabolic rate also will be decreased as we age and when we are sleeping.</span>
Ponds and Lake Ponds and Lakes form when water collects in<span> hollows and low-lying areas of land. </span>
