Most of the time they become reproductive in the late winter and give birth in early spring. Thanks for posting your questions on brainly!
Biomass is a renewable source of energy. I'd say coal mining can pollute water supplies and kill fish and aquatic plants.
The vascular system of the plants are responsible for transporting water and needed nutrients for the plant to survive. Hence, when this is disturb certain transpirational pull is also disrupted, rendering the plant unable to collect water effectively. Thank you for your question.

It's letter A - Obligate anaerobe.
<em>Obligate anaerobes</em> are microorganisms killed by normal atmospheric concentrations of oxygen. A <em>facultative anaerobe</em> prefers to produce energy in the presence of oxygen but can survive without it. <span>A <em>photoautotroph </em>is an organism that converts light energy into chemical energy. </span><span>Prokaryotes may perform </span>aerobic<span> (oxygen-requiring) or </span>anaerobic<span> (non-oxygen-based) metabolism and some can switch between these modes. Since we're talking about an environment without oxygen and dies when exposed to oxygen, the preferable answer is A.</span>
