Answer:
carbohydrates are important in the body because they contribute to the body's ability to produce ATP
Answer:
To produce ATP.
Explanation:
Carbohydrates are important in the body because they contribute to the body's ability to produce ATP.
When a person eats food, the carbohydrates in it are broken down which in turn produce an energy rich component called ATP (adenosine triphosphate).
These carbohydrates are broken down by certain enzymes in the small intestine which are present in the form of glucose which then yields ATP to drive the cell.

for every C, G us paired with it
Answer:
The answer is Isoleucine, Glutamate and Proline.
Explanation:
First, the sequence needs to be transformed from DNA to RNAm, so the A's are transformed into U (uracil in RNA) and the G's are transformed into C's (and vice-versa) and the T's into A's. Then, when the RNAm chain is obtained, the first trio turns into (AUC) that codes for Isoleucine, then the second one is (GAA) and it's Glutamate, and finally the third trio codes for Proline (CCG). The fourth part only has two nucleotides so it's impossible to know the amino acid to which it codes.

O
A. Ancient plant remains
O
B. Melted metamorphic rock
O
C. Sedimentary rock particles
C
D. Ancient marine organisms
The answer is A, ancient plant remains
Explanation:
Final answer:
Coal is composed mainly of ancient plant remains that were subjected to high temperatures and pressures over millions of years, resulting in a combustible sedimentary rock that can be used as fuel.
Explanation:
Coal is composed of ancient plant remains. It is a complex solid material that originates primarily from plants that died and were buried under sediment millions of years ago. These plants were then subjected to high temperatures and pressures, leading to the formation of coal. Coal is considered a sedimentary rock, and in some classifications, it is also identified as a biologic sedimentary rock because it forms from the accumulation and alteration of plant matter. There are four main types of coal, which are lignite, subbituminous, bituminous, and anthracite, with anthracite being the highest rated due to its heat generating capacity and lower sulfur content.
Experiments in which all variables are identical except for one are called _____ experiments
Answer:
controlled experiments
Explanation:
Experiments in which all variables are identical except for one are called controlled experiments. This where an observer tests his hypothesis by looking on changes that were brought about by one variable. The results are always dependent on one adjusted variable.
ANSWER:
The controlled experiments are the ones in which all variables are identical except for one.
EXPLANATION:
The experiments are conducted only by bringing about changes to one variable rather than all variables. Controlled experiments are used to test hypothesis in which changes are brought about by adjusting only one variable rather than all the variables used in the hypothesis experiment. The results of these experiments vary with the changes that are brought about in the one dependent variable.2 Points
What happens when alleles for a trait are codominant?
Final answer:
When alleles are codominant, both are expressed equally in the phenotype. This is observed in the AB blood type in humans, where both A and B antigens are visible. Codominant traits lead to unique phenotypes with both inherited traits being equally expressed.
Explanation:
When alleles for a trait are codominant, it means that both alleles are expressed equally in the phenotype of the organism. Unlike complete dominance where only the dominant allele is visible, or incomplete dominance where a blend of both alleles is seen, codominance allows each allele to maintain its identity and be seen distinctly in the phenotype.
A classic example of codominance can be found in the ABO blood group system. Individuals with type AB blood inherit one A allele and one B allele. These alleles are codominant, allowing for the expression of both A and B antigens on the surface of red blood cells. Likewise, in plants, a flower with codominant alleles for petal color may display both red and white petals simultaneously. This distinct expression of both alleles leads to unique phenotypes that do not blend but rather are expressed together.
In a Mendelian monohybrid cross involving codominance, the heterozygous offspring will express both alleles. The genotypic ratio remains the classical 1:2:1, typical of Mendelian inheritance, yet the phenotypes will distinctly show both inherited traits.

Access to potable water is most heavily limited by _______.
Access to potable water is most heavily limited by money.
Money can be a limiting factor for people, and with the lack of money, accessing potable water may be difficult.
Answer:
Around the world the most significant restriction on access to potable water is money. While access to raw water sources, clean or otherwise, is important, the purification process itself is expensive. Once water has been rendered potable, it is important that it be delivered without reintroducing contamination. The most convenient way to deliver potable water is through underground pipes, which requires expensive infrastructure.
Explanation:
The burning of coal to generate electricity has been good in some ways and bad in others. The electricity has allowed for an improvement in many areas of life, but the burning of coal is also responsible for a great deal of pollution. Which activity helps solve the pollution problem through the use of new technology ?
Technologies such as Carbon Capture and Storage (CCS), clean coal technology, and the use of renewable energy sources can help solve the pollution problems caused by burning coal to generate electricity.
Explanation:The pollution problem caused by burning coal for electricity can be addressed using new technologies in various ways. One method is Carbon Capture and Storage (CCS), a technology designed to trap and store carbon dioxide produced from coal-fired power plants to prevent it from being released into the atmosphere. Another way is the use of clean coal technology, aimed at improving the efficiency of coal burning and reducing greenhouse gas emissions.
Furthermore, exploring and expanding the use of renewable energy sources such as wind, solar energy, and hydropower as an alternative to burning coal plays a significant role in reducing pollution and counteracting the warming effect on the planet.

Which of the following will most likely happen to an enzyme if it is placed in
an environment that is too acidic or too basic?
Answer:
The enzyme will no longer bind to the substrate, slowing or stopping the chemical reaction
Explanation:
The enzyme will get denatured and therefore its active site (that binds the substrate) will be deformed and unable to catalyze reactions. The enzymes, mostly made of folded proteins, are made stable by the interactions between the protein’s amino acids side groups. Changes in the pH of the solution influence the charges of these groups hence altering their interactions. This causes the protein enzyme to deform causing it to lose its function.

A volcano that is fairly symmetrical and has both layers of lava and pyroclastic deposits is a _____.
cinder cone volcano
pyroclastic volcano
composite cone volcano
shield volcano
composite cone volcano
Answer:
Composite cone volcano
Explanation:
Composite Cone Volcanoes are large volcanic buildings with long, generally conical shape, usually with a small crater on the summit and steep flanks, constructed by the interleaving of lava flows and pyroclastic products emitted by one or more conduits, which can be punctuated. over time by episodes of partial cone collapse, reconstruction and changes in conduit location.
Compound volcanoes are found in all regions of volcanism, but it is in plate convergence zones, where a tectonic plate subdows (plunges) toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are most abundant. The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.
Define Fitness as it relates to adaptation
Answer:
In Biology, the terms "fitness" and "adaptation" go in hands with hands. Fitness can be defined as the capability of an organism to cope with environmental fluctuations in such a way that it is better able to reproduce and survive in that environment. This process in turn increases the adaptation of an organism for that environment. So adaptation can be considered as the process in which living organisms due to their better fitness acquire some characteristics which help in their improved survival.
The more an organism possesses fitness, the more it will have the adaptations towards adverse environmental fluctuations and ability to survive.

What will most likely happen to a plant that does not receive any water?
Answer C The light dependent reactions will not occur
Explanation:
Plants wilt without sufficient water due to loss of turgor pressure and water moving from the plant to the soil under drought conditions.
If there is not sufficient water, pressure exerted by the vacuole is reduced, and the cells become flaccid causing the plant to wilt. Dry soil has a lower water potential than wet soil, leading to water moving from the plant to the soil. Under drought conditions, the stomata close to conserve water, and leaves may be shed if the drought continues.
