Answer:

The cryosphere is the portion of the Earth's surface where water is in solid form. It thus includes sea ice, lake ice and river-ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground. The snow cover has the largest extent, with a maximum area of more than 45 106 km2 (Table 1.1). Because of the present distribution of continents, land surfaces at high latitudes are much larger in the Northern Hemisphere than in the Southern Hemisphere. As a consequence, the large majority of the snow cover is located in the Northern Hemisphere (Figs. 1.15 and 1.16). The same is true for the freshwater ice that forms on rivers and lakes in winter. Both the snow cover and freshwater ice have a very strong seasonal cycle, as they nearly disappear in summer in both hemispheres (Table 1.1).

Answer:

B) They are producing more crops

Explanation:

GMOs are designed to increase crop productivity because of supply and demand, which in turn makes the supplier more money, and more happy people/companies that buy the crop. Additionally, the other answer choices would be considered bad traits.

Explanation:

Nitrogenous bases basically pairs with bases that are complementary. The correct option is B.

Nucleobases, also referred to as nitrogenous bases or purely bases, are nitrogen-containing biological molecules that form nucleosides, which are then constituents of nucleotides, all of which are the basic building boxes of nucleic acids.

A set of 5 nitrogenous bases is used to build nucleotides, which then in results nucleic acids such as DNA and RNA.

These bases are critical because their sequencing in DNA and RNA is how information is stored.

A base pair in DNA are complementary to each other. Under normal conditions, the nitrogen-containing bases adenine (A) and thymine (T) pair, whilst also cytosine (C) and guanine (G) pair.

The structure of DNA is formed by the binding of these base pairs.

Thus, the correct option is B.

Answer:

Structures that have lost their use through evolution are called vestigial structures. They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose..

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.

Answer:

Calvin Cycle

Explanation:

The Calvin cycle takes over where the light reactions end. It uses chemical energy stored in ATP and NADPH (from the light reactions) and carbon dioxide from the air to produce glucose, the molecule that virtually all organisms use for food.

Answer:

The bone weights more as the bone's thickness is wider for a compacter bone.

Explanation:

Compact, sometimes called cortical bone, thick bone with firm organic soil and inorganic salt in the ossic matrix leaving only narrow gaps in which the osteocytes or bone cells are present. The bone is sometimes called the cortical bone.

Answer:

The bone weighs more as its thickness grows wider, causing a more compact bone.

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.

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.

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.

Anaphase and Prophase

Explanation:

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.
