The correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new source of energy.
Explanation
As is mentioned in the statement, the energy from a hydroelectric plant is obtained through the movement of water that makes move some blades which produce energy with it. lLater, this is transformed and transported to the cities. However, to obtain these clean natural renewable resources, it is necessary to take into account what environmental factors may be affected with the implementation of a hydroelectric plant, because the operation of hydroelectric can affect natural processes such as fish migration, patterns of reproduction, feeding, among others that take place in a river, having negative consequences for these species which would cause an imbalance in nature. According to the above, the correct answer is D. Fluctuations of limiting factors in the ecosystem affected by the new energy source.

Why does sound travel faster through a solid object than in the air?
Answer:
Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
Answer: Because molecules in a solid are packed together tightly.
Explanation: The molecules of a solid immediately collide and the compression wave travels rapidly.
Algae Population growth
Answer:
Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping, including species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 m in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants.

Explanation:
Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. Because CO2 produces an acid in water, BTB can indirectly measure how much CO2 is present in a solution. When placed in solutions with neutral pH (little CO2), the solution appears green. In solutions with low pH (high CO2), the solution appears yellow.
A teacher performed a demonstration to investigate how photosynthesis and respiration cycle carbon and oxygen. She placed a few drops of BTB in a test tube containing distilled water. Because distilled water has a neutral pH, the solution appeared green. The teacher used a straw to blow into the solution, and the solution turned yellow. She then placed an aquatic plant into the test tube, covered it to keep it air tight, and placed it under a light for 24 hours.
What color would the solution in the test tube be after being in the light, and what would it be if it were then placed in the dark for 24 hours, and why?
A
Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.
B
Yellow after being placed in the light because the plant would release CO2 by photosynthesis; green after being placed in the dark because the plant could not photosynthesize in the dark.
C
Green after being placed in the light because the plant would remove CO2 by photosynthesis; green after being placed in the dark because no CO2 would enter the tube since it is air tight.
D
Yellow after being placed in the light because the plant would release CO2 by photosynthesis; yellow after being placed in the dark because no CO2 could leave the tube since it is air tight.
Answer:
A. Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.
Explanation:
According to this question, Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. The presence or absence of CO2 in a solution decreases or increases the pH of the solution respectively.
- BTB appears green in a neutral pH i.e. little CO2
- BTB turns yellow in a low pH i.e. high CO2
Plants, in the presence of light, will perform photosynthesis and use CO3 as a reactant while in the dark, will perform cellular respiration and release CO2 as a waste product. Hence, in this case where an aquatic plant was placed into a test tube and covered it to keep it air tight.
- When placed under light for 24 hours, the aquatic plant will undergo photosynthesis and remove CO2 from the solution to make the solution appear GREEN due to neutral pH.
- When placed in the dark for 24 hours, the aquatic plant will undergo cellular respiration and release CO2 into the solution making the solution appear YELLOW due to low pH.
what happened to the red blood cells after the sugar was added to the solution
Answer:
Studies revealed that glucose binds with the RBC membrane and intracellular proteins and increases membrane rigidity. The thing is that the concentration of glucose in the solution used is less than compared to the concentration of the same inside RBC and the cells swell up due to endometriosis.

Explanation:
The unique features with regarding the se-xual reproduction should contained only half the genetic material of the parent.
What is Meiosis?Meiosis refer to the special type of the cell division with respect to the germ cells with respect to the organism that should be se-xually reproduction.

The bacterium E. coli can use carbon sources other than glucose for
nourishment. Arabinose, a five-carbon sugar, is one example of such an
alternative food source. However, E. coli does not metabolize arabinose if
glucose is plentiful in its environment. E. coli only metabolizes arabinose if it
is the only food source available. Which of the following best explains how
the cell's function is enhanced by this gene structure?
A. This sequence of genes ensures that the enzymes needed for
arabinose metabolism are transcribed in the same order in which
the cell will need them.
B. The regulator, activator, and promoter regions ensure that the
genes for metabolizing arabinose are not mutated or deleted
during DNA synthesis.
C. The regulator gene ensures that the genes are transcribed at all
times, to be sure the cell is ready in case arabinose becomes
available.
D. This gene sequence ensures transcription of arabinose genes only
when arabinose is available, saving the cell from expending energy
unnecessarily

3)What is the epiglottis?
4)Why do the walls of the stomach secrete hydrochloric acid?
5)Which TWO parts of the alimentary canal make up the small intestine?
Answer:
3)The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.
4)Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
5)Made up of three segments -- the duodenum, jejunum, and ileum -- the small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver.

What is the correct Oder in which the three types of neurons work to respond to a stimulus
Answer:
Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands. Draw and label the structure of a typical nerve cell.
Explanation:
what prevents lipids from mixing in water
Answer: lipids are nonpolar
Explanation:
because water is polar and lipid is non polar, so it is insoluble in water that is it floats water
Answer:
Water molecules are polar because they have positive and negative ends, rather like little magnets. Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Since lipids have no charged groups, the water molecules have nothing to stick to and dont mix with them.
