Answer: By moving the turbines by water.

Explanation:

A dam is used to generate tidal power by using hydropower. The water is used to rotate the turbines and produce electricity.

Tidal power has a potential future as water can be used to produce electricity, the most common problem associated with this is procedure is low cost and limited sites.

The high speed of water moves the turbines and electricity is generated by the help of generators.

Egg membranes from three eggs were carefully taken out and labeled as a, b , c. Each of these membranes were filled with 1% solu
Readme [11.4K]

Answer:

The correct answer would be -

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

Explanation:

This experiment deals with tonicity as this solution will affect the tonicity of the egg membrane. In membrane A there are more solutes inside the cell than outside the cell so it is hypotonic solution so the movement of water will be towards inside the cell.

In membrane B the solutes are equal in both sides so there will be no movement as its isotonic condition while in membrane C the solution is in hypertonic situation as the solutes are more outside than inside.

Thus, the behavior of the membranes are-

Membrane A - Hypotonic solution - the movement of water towards inside the cell

Membrane B - Isotonic soltion - there will be no movement of water

Membrane C - Hyertonic solution - the movement of water towards outside of the cell

What is the correct term for variation in characteristics within populations of the same species? A variation in characteristics
Crazy boy [7]

Answer:

The correct answer would be phenotypic variation.

Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.

Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.

In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.

The rate of O2 production by the light reactions varies with the intensity of light because light is required as the energy sour
kupik [55]

Answer:

The correct answer is option a.

Explanation:

Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.  

In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.  

The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.

Which statement gives an advantage of multicellular organisms?
Illusion [34]

Answer:

D

Explanation:

Bacteria can reproduce quickly which is why it is sometimes hard to get rid of a cold.

Both types of cells carry out necessary functions to survive.

Size does not define a cell.

Multi-cellular organism have complex cell structure in which each cell has the ability to tend to it's necessary functions.

Hope this helps :)
