Answer:

<h3>DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).</h3>

IF most of the energy we use on earth comes from the sun –how does that energy (light and thermal) end up

____ [38]

Answer:

1: Chemical Energy

2: Kinetic Energy

3: Electrical Energy

4: Mechanical Energy

Explanation:

1: The energy held in food is called chemical energy. It is a form of potential energy held within chemical bonds between atoms.

2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.

3: The power for lights and stuff is Electrical Energy, ofc :]

4: The chemical energy in the food gets changed into the mechanical energy of moving muscles.

Hope this helps!! :D

Which is true about a daughter cell produced by mitosis? A. It is a haploid cell. B. It is connected to the parent cell. C. It c

ANTONII [103]

Answer:

D. It can function independently

Explanation:

A. Not a haploid, the daughter cell is going to be a diploid cell, because it is a body cell, not a sex cell; they are suppose to have the same amount of chromosomes as the parent cells.

B. It will go through cytokineses ( last step of the mitosis) the cells will not be connected to parent cell and is independent (D)

C. Inside the chromosomes, no matter it is a haploid or diploid cell, it will contain DNA.

D. After going through the cell cycle, the new daughter cell produced will be a new individual and do not connect to other cells.

A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and mol

mr Goodwill [35]

Answer:

Crustaceans and Molluscs play an important role in the oceanic carbon sink.

Explanation:

Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.

CO2 is not combustible.
creates carbonic acid in the oceans.
Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)

Most fertilizers contain ammonia. Ammonia (NH3) forms when hydrogen reacts with nitrogen. Which balanced equation represents amm

Lana71 [14]

The balanced equation for ammonia (NH3) is 3H2 + N2 ď 2NH3. This equation starts from H2 + N2 ď NH3. We have 1 N and 3 H on the right side (the product side) of the equation, so we multiply each by 2 to get 2 N and 6 H. We do this so that we donâ€™t have an odd number of H atoms. We then balance the left side (the reactant side) of the equation with the right side, N is already balanced, but we have to multiply H by 3 to get 6 H atoms (to match the right side of the equation.
