which molecule is used up in photosynthesis?
Final answer:
During photosynthesis, carbon dioxide, water, and solar energy are used to produce glucose and oxygen. ATP is generated during the light-dependent reactions and is vital for the subsequent synthesis of glucose in the Calvin cycle.
Explanation:
The molecule used up in photosynthesis includes carbon dioxide (CO2), water (H2O), and also relies on solar energy to drive the reactions. During the light-dependent reactions of photosynthesis, ATP (adenosine triphosphate) is created, which along with NADPH, is used in the Calvin cycle to fix carbon dioxide, producing glucose. The overall chemical equation representing this biochemical process is 6CO2 + 6H2O → C6H12O6 + 6O2.
The ATP and NADPH generated are crucial for the synthesis of glucose in the process, which works coherently with sunlight absorbed by chlorophyll to facilitate the production of energy-rich sugar molecules. It is important to understand that the glucose produced from photosynthesis is an energy storage molecule and is later used by organisms to produce ATP through cellular respiration.
Answer: water and carbon dioxide
Explanation: yes
Proteins and carbohydrates perform various functions in the body. They are needed for the proper development and growth of the body.
Answer:
Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals.
Protein is also important for the repair bones, muscles, cartilage, skin, and blood.
Breaking down carbohydrates yields monosaccharides such as glucose and galactose. Breaking down proteins yields amino acids. These subunits are essential for energy and various bodily functions.
When carbohydrates are broken down, they yield monosaccharides such as glucose, galactose, and fructose as products. These monosaccharides are simple sugars that can be absorbed by the body and used for energy.
On the other hand, breaking down proteins yields amino acids as products. Amino acids are the building blocks of proteins and are crucial for various functions, including building and repairing tissues, making enzymes, and supporting immune function.

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.What is coal composed of?
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.
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.
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.

How long should warm-up and cool-down activities take? Question 10 options: 30 minutes each 2 to 3 minutes each 5 to 10 minutes each 15 to 20 minutes each
Answer:
The correct answer would be option C, 5 to 10 minutes.
Explanation:
Warm up and cool down are the two periods in the exercise that have to be included when you do a workout. Warm up is the starting exercises of mild intensity in which the body prepares itself for the upcoming intense workout. Some simple exercises are done before starting the regular exercise. Warm up may include mild jumping, mild jumping jacks, etc. Warm up basically increases the blood flow to the muscles and prepare the muscles for the intense workout session. On the other hand, cool down is done after completing the regular intense workout session in order to relax the muscles of the body. Cool down may include mild walking or some stretches to relax the body muscles. Both warm up and cool down take 5 to 10 minutes each.
Answer:
The correct answer is "5 to 10 minutes each".
Explanation:
Warm-up and cool-down are activities that are essential to start and finish an exercise routine respectively, but usually are not considered part of the routine because they should not take too much time. According to fitness professionals, warm-up and cool-down activities should take 5 to 10 minutes each, where the longer the exercise routine the longer these activities should last.

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.

Explanation:
Adenine is paired with ThymineGuanine is paired with Cytosineso, for every A, T is paired with it
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.
