Hydrogen fuel cells are more expensive than fossil fuels.
Hydrogen fuel cells have a higher energy efficiency.
Hydrogen fuel cells create less pollution
i got it right on the assignment
The use of hydrogen fuel cells is preferable to using fossil fuels since they are more environmentally friendly and have a higher energy efficiency. So, the correct options are A and B.
What is Hydrogen fuel cell?The use of hydrogen fuel cells is preferable to using fossil fuels since they are more environmentally friendly and have a higher energy efficiency.
Because they transform the chemical energy of hydrogen and oxygen into electricity with an efficiency of about 50–60% as opposed to the 30–40% of burning fossil fuels, hydrogen fuel cells are more energy efficient than burning fossil fuels. This increases efficiency and reduces waste by converting more of the fuel's stored energy into usable work.
Burning fossil fuels produces a variety of pollutants, including carbon dioxide, nitrogen oxides, sulphur dioxide, and water, whereas using hydrogen fuel cells only produces heat and water as byproducts.
Therefore, the correct options are A and B.

Water can travel upwards in the small tubes within plants. This is:
A. Surface Tension
B. Adhesion
C. Cohesion
D. Capillary Action
Answer:
D i think maybe right not sure
Answer:
D. Capillary action
Explanation:
Capillary action is defined as "the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension." All of the other answers are technically right because they are all present when the water is traveling upward, but Capillary Action is the most correct answer provided because it is the description of what is hapeneing as a whole.
How does inorganic nitrogen from the atmosphere
(N2) get into living systems?
Answer:
When an organism excretes or dies, nitrogen is in the form of organic nitrogen in its tissues (e.g. amino acids, DNA). During the ammonification process, many fungi and prokaryotes then break the tissue down and release inorganic Nitrogen into the atmosphere as ammonia.
Explanation:
Plants use their roots for nitrogen compounds. When they consume the seeds, animals acquire certain chemicals. When plants and livestock die, or animals excrete waste, the organic nitrogen compounds return to the soil, where microorganisms known as decomposers break down their compounds.

Which has the larger ratio of surface area to volume, a tennis ball or a soccer ball?
Answer: Soccer Ball
Explanation: Because it is bigger and could hold more air.
The answer is Soccer Ball. Just because it is bigger and could hold more air.
What is the ratio of the surface location to extent limits?The ratio of surface place to an extent limits the dimensions of the cell textbf{the size of the cell} the dimensions of the mobile. This is due to the fact that the quantity of mobile will increase swiftly, the mobile's floor region decreases, to the factor that the ratio of floor place to an extent is a small price.
The surface vicinity to extent ratio is important for cellular diffusion in addition to cell department. So that you can live, cells require nutrients and oxygen to skip into the cell via its cell membrane, and they require waste to go away from the cells within the contrary course.

Where would a frameshift mutation cause the most damage?
Near the very end of the gene
Near the beginning of the gene
Near the center of the gene
All frameshift mutations are equal
Answer:
All frameshift mutations are equal
Explanation:
Frameshift mutation is a type of mutation caused by insertion or deletion of nucleotide base(s) in a genetic sequence causing that sequence to be read in a different way from what was originally planned.
The bases in the sequence of a gene is read in three's (codon), however, when one or more bases is added (insertion) or removed (deleted), the reading frame is altered causing the sequence to be read in a completely different order that can result in a protein that is non-functional.
However, FRAMESHIFT MUTATION is so potent that it affects the sequence no matter where it occurs. In other words, the effect of all frameshift mutations are equal.

Complete the table below to show the absorption of micro (small) nutrients, that are formed by the digestion of macro (large) nutrients.
Answer:
The correct answer is -
Protein - amino acids
Glycogen - glucose or monosaccharides
Fats - fatty acids
Explanation:
Once protein sources reach the stomach of an individual, An enzyme called proteases and HCl break these proteins into small amino acid chains that were bonded with a peptide bond, thus protein macronutrient is absorbed in the form of amino acid.
Glycogen is stored in the muscles and liver for energy and digested into glucose by enzymes called amylase and maltase.
Fats are the main source of fatty acid in the body and help in providing fatty acid for the body requirements.

Who are the key players in dna replication
The key players in DNA replication are enzymes. These enzymes are helicase, primase, DNA polymerase, and ligase.
What is the role of enzymes in DNA replication?At the replication fork, the enzymes responsible for DNA replication work in concert to simultaneously synthesize the DNA's leading and lagging strands. The replication DNA polymerases (Polymerase III in E. coli) produce dimers to complete this activity.
The enzyme DNA polymerase, also referred to as DNA pol, is one of the main players. DNA pol I, DNA pol II, and DNA pol III are the three primary forms of DNA polymerases found in bacteria.
DNA pol III is currently understood to be the enzyme needed for DNA synthesis, whereas DNA pol I and DNA pol II are mostly needed for repair.
Therefore, the key players in DNA replication are enzymes. These enzymes are helicase, primase, DNA polymerase, and ligase.

is the intrusion the youngest rock in the section how do you know?
Answer:
Explanation:
The fault cuts through all three sedimentary rock layers (A, B, and C) and also the intrusion (D). So the fault must be the youngest feature. The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers. By the law of superposition, C is the oldest sedimentary rock, B is younger and A is still younger.
