Answer:
In cellular respiration, stored chemical energy in organic molecules is converted to ATP molecules- 3)
ANSWER:
The correct option is C- Organic molecules are converted to "ATP molecules".
EXPLANATION:
Cellular respiration is the process that provides energy for the important life processes. Cellular respiration is essential for all living organisms and therefor all living cells must carry out this process. In this respiration, ATP is released which is essentially energy needed for all life processes of an organism. Cellular respiration can be aerobic when it takes place in the "presence of oxygen" or it can be anaerobic i.e. respiration takes place without the presence of oxygen.How doe the natural process of meiosis support evolution
Answer:
Meiosis is sexual reproduction, which involves two organisms mixing their genes together to produce new offspring.The more genetic variation there is within a population, the faster it will evolve
Explanation:
During Meiosis recombination occur which cause mixing of segments of chromosomes that can lead to variation.
Variation is the leading cause of evolution.What is variation?Variations arise due to mutation, recombination at the time of gamete formation or due to environmental factors.
Variations can be categorized into two types:
Genotypic variations are caused due to changes in the chromosome or genes or due to various alleles of the same gene. They are inheritable variations.What is evolution?Evolution is the change in heritable traits of biological populations over successive generations. Evolutionary processes give rise to diversity at every biological organization level. All life on earth shares a common ancestor known as the last universal ancestor.

Suggest reasons for using synthetic forms of drugs rather than using plant extracts directly
Answer:
they lead to quick recovery
Explanation:
they contain chemicals made by professionals which lead to quick recovery
Synthetic drugs offer consistent dosages, reliable supply, and are often more potent with fewer side effects than natural plant extracts. They also contribute to lower toxicity in both human health and the environment.
The use of synthetic forms of drugs rather than plant extracts directly has several advantages. Primarily, it allows for consistent dosages and purities, which are crucial for ensuring the efficacy and safety of medications. Furthermore, because some medicinal plants are limited in availability and can be affected by environmental factors, synthesizing medications offers a reliable supply avoiding shortages and high costs associated with plant-based sources. Percy Julian's work in mass producing drugs such as cortisone and hydrocortisone stands as a testament to the success of such an approach. The synthesis process can also lead to drugs that are more potent, require lower dosages, and have fewer side effects compared to their natural counterparts. Moreover, synthetic methods can minimize the toxicity to human health and the environment.

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.

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.

O
A. Chromosomes are duplicated.
O
B. The cell splits in two.
O
C. DNA separates into two nuclei.
O
D. Cytoplasm is manufactured.
Answer:
chromosones are duplicated just took test
Explanation:
Chromosomes are duplicated during the S phase of the cell cycle. Therefore, the correct statement is option A.
What is the S phase of the cell cycle?S phase, or the synthesis phase, is the second phase of interphase in the cell cycle. During this phase, the cell undergoes DNA replication, where chromosomes also get duplicated. Each chromosome consists of two identical chromatids connected by a centromere.
The process of DNA replication during the S phase involves the use of several enzymes and proteins. The process starts with the unwinding of the DNA double helix structure by the helicase enzyme creating a replication fork to which DNA polymerase enzymes attach and starts the replication process by copying the template strands of DNA.
As the polymerase moves along the template strand, the enzyme adds complementary nucleotides to create a complementary strand of DNA. Each nucleotide before adding is checked by proofreading enzymes to ensure the new DNA strand is error-free.
Therefore, chromosomes are duplicated during the S phase.

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.

How does transpiration pull work?
Answer:
transpiration pull –The loss of water through evaporation from the leaves must be replaces by water coming up the xylem. Water molecules are attracted to each other due to cohesion between them. These forces are strong enough to hold the molecules together in a long column.
Explanation:
Transpiration is the loss of water from the plant through evaporation at the leaf surface. It creates negative pressure (tension) at the leaf surface, causing water to be pulled up from the roots.
Explanation:Transpiration is the loss of water from the plant through evaporation at the leaf surface. It creates negative pressure (tension) at the leaf surface, causing water to be pulled up from the roots. This is known as the cohesion-tension theory of sap ascent.

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.

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
HELP!! The figure below shows ocean currents. Where will climate change slow the currents the most, causing colder temperatures, and why?
Answer:
Along the Kuroshio Current, because it is carrying water north towards melting ice caps
Explanation:
The ocean currents have the tendency to be faster when they are warmer, and to be slower when they are colder. The reason for this is that the warmer water is less dense, thus it can move more quickly, while the colder water is denser, thus heavier, so it moves slower. The Kuroshio Current moves from the lower latitudes toward the higher latitudes. As it does, this ocean current is becoming colder and colder as it gets closer to the higher latitudes, so it is becoming denser, heavier, and because of it slower. Another thing that will contribute to this current's slowing down are the melting ice caps because of the climate change, as they will make the water even colder, and the Kuroshio Current will come across this cold water, so it will decrease its speed significantly.

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.

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.Which of these is an advantage of wind energy?
