You can tell from looking at a nuclear reaction that fusion has taken place by an increase in the total number of protons and neutrons which is denoted as option A.
What is Nuclear fusion?
This is referred to as a form of reaction which involves the fusion of two or more light nuclei to form a heavier nucleus.
We are ware that the nucleus comprises of subatomic particles such as proton and neutron which therefore means that a heavier nucleus being formed will lead to an increase in the total number of protons and neutrons hence option A was chosen.

after electrophoresis dna fragments through an agarose gel, you examine the dna band that is closest to the positive electrode. how does this dna fragment compare to the others on the gel?
This DNA fragment is smaller as compared to others.
In the field of science, gel electrophoresis can be described as a technique by which DNA fragments are separated based on their charge-to-mass ratio.
Those DNA fragments that are smaller will move faster as compared to the larger ones. This is because the charge on each DNA fragment will be the same but the smaller DNA fragments will be able to move faster.
Hence, the DNA band that is closest to the positive electrode will be able to travel faster as compared to others.

The statement; "Biologists conclude that sardine fish form tight clusters called "bait balls, such as the one shown in the image, because this behavior protects them from predators." is true
What are the predators?Bait ball behavior is not limited to sardines; other small schooling fish, such as herring, anchovies, and mackerel, also exhibit similar clustering behaviors for similar protective reasons. The formation of bait balls is a remarkable example of collective behavior in the animal kingdom and serves as a vital survival strategy for these small fish species.
Biologists have observed that sardine fish (and other small schooling fish) form tight clusters known as "bait balls" as a defense mechanism against predators.

susan is a consultant for a grocery store chain that wants to open several new stores in the st. louis area. she has selected several sites for the company to consider based in part on projected population growth near those sites. what isolating mechanism does this best illustrate?
The isolating mechanism which best illustrates Susan's consultancy is better expectations of future resource value.
Susan is making an investment in future value thus, the company can gain a competitive advantage by having better expectations of a resource's future value. A company can gain a long-term competitive advantage by consistently setting higher expectations over time.
Isolating mechanism: A steady stream of economic profits and the persistence of intra-industry firm differences over time are both explained by isolating mechanisms, which are also referred to as barriers to imitation (Mahoney and Pandian, 1992). Similar to entry barriers and mobility barriers, isolating mechanisms operate on different levels.
Barriers to imitation that prevent a company from competing are:
1. Better expectations of the value of future resources—investment in future value
2. Path dependence—the options faced are limited by past decisions;
3. Causal ambiguity—the cause and effect of a phenomenon are not readily apparent
4. Social complexity—the interaction of various social and business systems and
5. Intellectual property (IP) protection—a critical intangible resource that can serve as a powerful isolating mechanism. The main types are Trade secrets, designs, patents, copyrights, and trademarks.

In the gluteus maximus, each motor unit controls a _____________ amount of muscle fibers than a motor unit in the eye muscles.
In the gluteus maximus, each motor unit controls a greater amount of muscle fibers than a motor unit in the eye muscles.
The primary hip extensor muscle is the gluteus maximus. It is the largest of the three gluteal muscles which determines the shape of the hips. Eyes need to move with precision and with a high level of control, which is made possible by the fact that there are fewer muscle fibers connected to each neuron. This is the reason why motor unit in gluteus maximus controls a greater amount of muscle fibres than the eye.
Smaller, lower threshold motor neurons in the muscle's small motor units will be more excitable and will fire first to their skeletal muscle fibers, which also tend to be the smallest. This is how eyes work efficiently. On the other hand, limbs requires greater amount of movement and thus have a larger muscle.

When an experiment is repeated and the new results are different from the original results, what could you assume to be true?
The original experiment may be inaccurate and further experimentation is needed.
The accuracy of measurements depends on the quality of the measuring equipment and the skill of the scientists involved. For the data to be considered reliable the variability of the values should be small. Repeated scientific research increases credibility. Results may change over the course of different studies or under different conditions.
It is therefore important that the experiment itself is reproducible. A reproducible experiment should but need not give the same results when performed by different people at different times and preferably under similar conditions. Repeating an experiment multiple times can help determine whether the data are random or normal. Avoid jumping to conclusions without sufficient evidence.

more free energy is released during the krebs cycle than during glycolysis, but only 2 moles of atp is produced for each mole of glucose undergoing glycolysis. most of the remaining free energy that is produced during the krebs cycle is used to a) synthesize gtp. b) reduce nad and fad. c) release as heat. d) oxidize pyruvate.
The Krebs cycle releases more free energy than glycolysis does, although only two moles of ATP are created for every mole of glucose that is glycolysis. Reducing nad and fad uses the majority of the free energy that is still created during the Krebs cycle.
What is meant by the Krebs cycle?The second crucial stage of oxidative phosphorylation is the Krebs Cycle, often known as the citric acid cycle. The Krebs cycle converts the energy from the smaller, 3-carbon glucose molecules produced by glycolysis into electron carriers, which are then utilized in the electron transport chain to create ATP.
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and a crucial step in aerobic respiration.
