Answer:

I think the answer is A.

Explanation:

Ponds and lakes are both inland bodies of freshwater that contain living creatures. Lakes are normally much deeper than ponds and have a larger surface area. ... All the water in a pond is in the photic zone, meaning ponds are shallow enough to allow sunlight to reach the bottom.

  The yearly process known as thermal stratification. A pond that is thermally stratified simply means that there is a noticeable temperature gradient as the water gets deeper. You may have noticed this in summer while swimming.

In fast-twitch oxidative-glycolytic fibers, their rapid increases in force rely on the ________ activity where rapid relaxation
Kitty [74]

Answer:

1. myosin ATPase

2. Ca2+-ATPase

Explanation:

ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.  

These fibers have the  ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.

During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.

Why do warmer and wetter biomes have higher net primary productivity
Andrej [43]
<span>biomes vary in their rates of net primary production-biomass that remains after cellular respiration limited by sunlight and nutrients available In general, warmer and wetter biomes have higher net primary productivity than colder and drier biomes. The reason for this trend is that plants require sunlight, water, and temperatures warm enough to grow. This is true even in aquatic ecosystems, where sunlight and the availability of nutrients determine the level of net primary productivity.</span>

Which of the following statements about vicariance and dispersal is most accurate?
V125BC [204]

Answer:

Answer is A. Vicariance does not require organisms to disperse.

Explanation:

Vicariance occurs when there is a sudden occurrence barrier , such as geographical area barrier that cause the isolation of species of organisms.

Dispersal involves the movement of the organism while vicariance is the change in environment due to sudden occurrence in the area.

In this case, vicariance  does not involve movement of organisms while dispersal involves movement of organisms.

Which of the following pairs is not correctly matched?
Elden [556K]

Answer:

B

Explanation:

T tubules do not generate ATPs. This is done by mitochondria. T tubules are the invagination of cell membranes into the muscle cells. They allow for rapid actuation of the action  potential by the muscle cells. They do this by synchronizing the release of calcium ions that are important in muscle contraction.
