Which reactant of photosynthesis is also involved in climate change?

choli [55]

Answer:

B. Carbon dioxide

Explanation:

First of all, let’s write out the photosynthesis equation to identify the products and reactants.

6CO2 + 6H2O + energy —> C6H12O6 + 6H2O

In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.

In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.

Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.

We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.

Therefore, the best answer choice is B. Carbon dioxide

A. external
These types of signals are observed when there is a cut on the body. The epidermal cells lose contact with one another and divide faster until they are in contact once again. After they come into contact, division slows down again.

How does the concept of a circle relate to cyclins?

baherus [9]

The progression of a cell by the cycle of cell is regulated by the protein family Cyclic

Explanation:

In the year 1982, Cyclin was located by Timothy Hunt as a family of proteins which has a vital function in the progression of a cell.
CDK enzymes or ‘cyclin dependent kinase’ gets activated by it that synthesizes the cycle of the cell.
The concentration of this protein moves in a cyclic way in the cell cycle. No enzymatic function is seen in them but it aims at CDK’s different location.

Almost 50 percent of water withdrawn in the US, is used up by thermoelectric power plants. The table below shows the amount of w

sp2606 [1]

Answer:

The number of thermal power plants increased between 1950 and 1975.

Explanation:

Here, the table that shows the amount of water withdrawn in billion gallons per year, between 1950 and 2005,

Year 1950 1965 1975 1990 2005

Amount 180 340 420 410 410

Since, 420 > 180,

Also, 50 percent of water withdrawn is used up by thermometric power plants.

Thus, thermal power plants in 1975 > thermal power plant in 1950

Therefore, the number of thermal power plants increased between 1950 and 1975.

Second option is correct.

Note : first option is incorrect.

Since, by the above table,

The least amount of water used by power plant is 180 billion gallons per year,

Thus, third option is incorrect,

Now, the table does not represents energy produced,

Fourth option can not be said correct.
