Which of the following accurately describes the use of fossil fuels for energy?

A species of fish evolved over thousands of years to have gills that allowed the fish to swim deep in the sea. What’s the effect

hammer [34]

Answer:

genetic modification competitors increase

Explanation:

The fish developed the gills because of genetic modification. Because the fish are now able to swim in deep water, their competitors in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.

Breaking away of the cell membrane from the cell wall in a plant cell as water leaves the inside of the cell?

liberstina [14]

The shrinking of a plant cell membrane away from the cell wall when placed in a hypertonic solution is called a plasmolysis... I don't know if that can be of any help :)

BIOLOGY HOMEWORK

bulgar [2K]

Answer: The only reaction performed by chloroplast through its chlorophyll is photosyntesis. Therefore the chemical formular is below.

C02 + H20 → C6H1206 + O2+ H20.

(carbondioxide) + (Water) Chlorophyll (glucose) +(oxygen)+ (water)

and

enzymes .

This is the single reaction of the process of photosynthesis.However two interconnected reactions are involved light dependent stage and light independent stage.

The first reaction takes place in presence of sunlight, and it is called Photolysis of water.it is the spiting of water to H+, electrons and Oxygen. This is the source of oxygen seen above.

4 H20→ 4H+ + 4e- + 02.

The light independent stage; the hydrogen ion from the photolysis is transfer to the light independent stage to reduce the C02 to produce glucose.In the first equation seen above.

Since chloroplast performs photosynthesis through action of its chlorophyll, The above reaction describes the chemical formula.

B.

The cell wall of plants is made up of the middle lamella, the primary cell wall and the secondary cell wall .

Cellulose a complex carbohydrate is the major components. It contains, monomers of glucose in small units linked to one another by bonds.

C

Vacuole helps in plant turgidity needed for uprightness. when filled with water provides turgor pressure increases as the cell membrane pushes against the cell wall. The resulted turgidity helps the plants to maintain resistance to external pressure and therefore resist the effects of gravity.

What is Chlamydomonas?

saveliy_v [14]

Chlamydomonas is a unicellular algae. It occurs in many Varieties .Most of these are free floating,fresh water green algae.

<h2>More information</h2>

the plant body is unicellular and biflagellate.
the cell is spherical or cylindrical in shape .
the Protoplasm of the cell is always surrounded by a thin cellulose wall .
a pair of flagella of equal size is present at the anterior end. it moves by the lashing actions of the flagella.
usually two contractile vacuoles are present .
it contains a single nuclear suspended in colourless portion of the cytoplasm .
