a Passing a loop of wire carrying a current over the other loop of wire.
A. Holding a loop of wire carrying current and then passing the other loop over it.
B. Passing a magnet near the loop of wire.
C. Holding a magnet stationary alongside the loop of wire.
Answers
Answer:
Okay so. I'm not sure if you mean by an electrical current so. I'll have to go with B. Passing a magnet near the loop of wire.
Explanation:
I believe this is it because if the magnet isn't touching then it cant conduct the current, which means the current would just end or not move at all.

The elephants represented in lanes 3 and 5 could have been a match to the ivory sample if you failed to amplify one allele in either the ivory or the sample, so you cannot exclude these choices without running the experiment multiple times. On the other hand, you can definitely eliminate the elephants in lanes 1, 2, 4, and 6. Explain why.
Answers
About the question:
I failed to find the result of the PCR / electrophoresis. However, I will try to explain when to still consider a sample, and when to exclude it.
Answer:
Probably elephants 1, 2, 4, and 6 exposed a pattern of lines that differed in most alleles from the ivory´s pattern. So they were considered to be different and, hence, excluded. However, elephants 3 and 5 only were different in one allele, which might be due to the amplification failure. In these last situations, the experiment must be run again, and include many markers.
Explanation:
The genetic profile is the series of alleles, characteristic of each individual, concerning a series of DNA fragments.
Once genetic profiles are obtained by using PCR/electrophoresis, they must be subjected to interpretation. The researcher must compare profiles to find concordance between individuals or the lack of it.
In the exposed example, probably we have a profile of the ivory sample, and we need to find out to what individual or population it belongs to. So we need to compare the pattern of bands of the different lanes with the ivory´s pattern of bands.
In resumed terms, if the ivory´s patterns completely match with another lane pattern, then this is the individuals or population to whom it belongs the ivory. However, if they do not match, we need to exclude this individual.
But this is not as easy as it looks like. Sometimes it is difficult to interpret the results because bands are not so clear, and sometimes there are failures during amplification, as said before in the statement of the problem.
In these situations, what you need to do is look for the lanes that match the most with the ivory one and discard those that differ the most. These last patterns probably belong to a different animal or population, that why they can be excluded. Individuals suspected of being the same as the individual understudy or belonging to the same population, must be subducted to a repetition of the study. Also, the use of several markers in the study increases the matches chances.
So, in the exposed example, if the amplification fails in one allele, elephants 3 and 5 could be a match to the ivory sample, probably because all the other alleles do match. You can only exclude them if, after the experiment repetition, the involved allele is still different. On the other hand, you can eliminate the elephants 1, 2, 4, and 6 because their pattern bands are significantly different from the ivory´s patterns, so you do not even need to repeat the experiment.

Answer:
A and F are phosphate groups
B and E are sugars
C and D are nitrogenous bases
Explanation:
just did it and it said it was right :)
In the given image, A and F are phosphate groups. B and E are sugars, while C and D are nitrogenous bases.
What is a nucleotide?The chemicals known as nucleotides are what make up DNA and RNA. A phosphate group, a sugar molecule, and a nitrogenous base are the three components that make them up.
The sugar molecule has five carbon atoms, making it a pentose, or five-carbon, molecule.
Geometric shapes, like the letters "B" and "E" in the image above, which each have a point that depicts a carbon atom, are used to represent these groupings.
Adenine (A) and guanine (G) are nitrogenous bases, whereas cytosine (C), uracil (U), and thymine (C) are pyrimidine bases (T).
The sole component that is constant throughout all nucleotides is the phosphate group, a molecule produced from phosphoric acid.
Thus, these are the parts of a nucleotide.

PLEASE HELP TAKING TEST NOW!!!!!!!!!!!! Which statement best describes ecological health? (1 point)

Ecosystem biodiversity determines ecological health via the types of different organisms in the area.
O Ecological health concerns the relationship between ecosystems, ecosystem services, and human health.
Ecosystem biodiversity determines ecological health via the amounts of different organisms in the area.
Answers
Answer:
ESPAÑOL ES LOS BIQUIGOS 1912
Ecological health concerns the relationship between ecosystems, ecosystem services, and human health. Therefore, option (C) is correct.
What is ecological health?Ecological health is the state and function of ecosystems as a whole. This includes their ability to provide essential services like clean air and water, the cycling of nutrients, and a place for wildlife to live. These services are important for human health and well-being because they directly or indirectly help us get food and water, keep our climate stable, and give us ways to have fun and grow spiritually.
Biodiversity is an important part of ecological health because it helps ecosystems stay stable and strong, but it is not the only thing that matters. Other things that affect ecological health are environmental stressors like pollution and climate change, as well as human activities like changing the way land is used and taking resources.

Answers
Answer:
Essential amino acids must be obtained from the foods we eat.
All essential amino acids must be obtained from the foods we eat. Thus, the correct option is A.
What are essential amino acids?An essential amino acid is also known as indispensable amino acid, these are the amino acids which cannot be synthesized from scratch by the organism fast enough to supply its demand in the body, and it must therefore come from the diet an individual eats. Of the 21 amino acids which are common to all life forms, the nine amino acids that humans cannot synthesize include valine, isoleucine, leucine, methionine, phenylalanine, tryptophan, threonine, histidine, and lysine.
Six other amino acids that are considered as conditionally essential in the human diet, meaning that their synthesis can be limited under special pathophysiological circumstances, such as prematurity in the infant or individuals in the severe catabolic distress. These six amino acids are arginine, cysteine, glycine, glutamine, proline, and tyrosine.
Therefore, the correct option is A.

6. In a Bio 207 lab you determine that the cost of transport for two fish from different species is 1 kJ/km for fish one, and 10 kJ/km for fish two. Provide an estimate of the swimming speed of each fish assuming that a) both fish have the same metabolic rate; b) fish two has a metabolic rate 10 times higher than the metabolic rate of fish one; and c) fish one has a metabolic rate that is 100 times smaller than the metabolic rate of fish two. Note that the ratio of metabolic rate to speed defines the cost of transport in units of energy/distance.
Answers
Answer:
b) fish two has a metabolic rate 10 times higher than the metabolic rate of fish one.
Explanation:
The fish one covers 1 kilometer distance by using 1 kilo Joule of energy while on the other hand, fish two covers consumes 10 kilo Joules of energy for covering the same distance i.e. one kilometer. This means that fish two has a metabolic rate 10 times higher than the metabolic rate of fish one. This high metabolic rate may be due to the higher mass of the fish two which needs more energy for the movement to cover distance of one kilometer.
