Some people see hydroelectric energy, energy harnessed from water
movement, as a clean alternative to fossil fuels. Others believe that utilizing
this renewable energy source is dangerous for the salmon populations that
rely on water sources for migration. Which environmental factor should be
taken into consideration when deciding to use renewable sources of energy
like hydroelectricity?
a. cost savings from switching from fossil fuels to renewable energy
increases in carbon emissions due to the production of new energy
systems
decreases in renewable energy as they are being used for human
sustainability
d. fluctuations of limiting factors in the ecosystem affected by the new
source of energy
C.

Answers

Answer 1

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.

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

what prevents lipids from mixing in water

Answers

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.

Why does sound travel faster through a solid object than in the air?

Answers

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.

How might a mutation in the DNA of the Piedmontese bull lead to muscle hypertrophy

Answers

Ans: The Piedmontese MSTN missense mutation G938A is translated to C313Y myostatin protein. This mutation alters MSTN function as a negative regulator of muscle growth, thereby inducing muscle hypertrophy. MiRNAs could play a role in skeletal muscle hypertrophy modulation by down-regulating gene expression.

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.

Answers

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.

4)Why do the walls of the stomach secrete hydrochloric acid?
5)Which TWO parts of the alimentary canal make up the small intestine?

Answers

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.
