Grizzly bears: As predators, bears keep down the numbers of several species, like moose and elk. They also carry and deposit seeds throughout the ecosystem. Bears that eat salmon will leave their dropping and the partially eaten remains that provide nutrients such as sulfur, nitrogen and carbon to the soil.
Answer: option D
The sodium potassium ion exchange move sodium and potassium in opposite direction in electrochemical gradients.
Explanation:
The sodium potassium pump is found in many animals plasma membranes and its moves the sodium and potassium ion in opposite direction across the plasma membrane with the hydrolysis of ATP(adenosine triphosphate) to supply the needed energy. It is an active transport process.
Answer:
A. The bacteria could no longer regenerate the NAD+ needed for glycolysis, so it would stop producing ATP.
Explanation:
According to the given information in this question, Lactobacillus acidophilus is a bacterium species that uses the lactic acid fermentation when there is no oxygen in its cell i.e. under anaerobic conditions. This means that it converts glucose to lactic acid during this anaerobic respiration process.
However, if the lactic acid fermentation pathway were blocked under an anaerobic condition, this means that it will be no longer be able to perform respiration and hence stop production of ATP. This is because the bacteria will no longer regenerate the NAD+ (electron acceptor) needed for glycolysis, so it would stop producing ATP. Note that, all living organisms, whether aerobic or anaerobic, undergo GLYCOLYSIS, which is the first stage of cellular respiration.
One advantage of asexual reproduction is that animals can <span>increase their numbers rapidly. The other options in the question are incorrect and so avoided. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has helped you.</span>
