Answer:

False

Explanation:

The salt concentration inside the body of freshwater fish is higher as compared to the water in which it live . However this is not the the case with marine fish which have low salt concentration in their blood  as compares to the salt in the sea water. In order to maintain sufficient salt in the fresh water fish body, specialized cell in the gills take ions from water and transport it into the blood.  Thus it can be said that A freshwater fish regulate its salt levels by pumping salt inward across its gills

Which process occurs during the light-dependent reactions in photosynthesis?
kobusy [5.1K]

Answer:

A. Water molecules are split.

Explanation:

The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.

These electron carriers are used in the light-independent reactions of photosynthesis.

During this process,  the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis

Complete the sentence: Ecosystem distribution
Step2247 [10]

Answer:

<em>Hypotheses may vary. Most students will probably state that ecosystems at </em>

<em>high altitudes will support little vegetation. </em>

Explanation:

Ecosystem distribution is different at different places. Regions at high elevations might usually have low varieties of plants and animals but it cannot be true for every ecosystem located as higher altitudes.

Some communities might be well adapted to live in the cold and hence progress rapidly.
