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.

Explanation:
Extra-large breakers are crashing into the surf. How will this affect the undertow? Make a prediction
Answer:
This will make the undertow return to the sea with greater intensity and violence.
Explanation:
Undertow is the movement of the wave in contrast to the sea, that is, it is the movement of the waves on themselves, which makes the sea very agitated, especially when these waves return to the sea with a lot of violence and force. Although this violence and force can be caused by the wind, extra-large breakers can also cause this effect, because the impact of the waves on the breakers, pushes the waves into the sea with more force, making them more violent and intense.

All essential amino acids
O must be obtained from the foods we eat.
are found in gelatin.
O come from enzymes.
are made in our body.
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.

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.
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.

Label A is a blue circle, label B is a grey hexagon, label C is adenine, label D is uracil, label E is a pink hexagon, and label F is a blue circle.
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.

Typically, acetylation of histone tails leads to ________. Typically, acetylation of histone tails leads to ________. relaxed packaging of the chromatin and increased transcription activation of topoisomerase removal of the protein components of the chromatin from the DNA tighter packaging of the chromatin and reduced transcription increased amounts of euchromatin relative to heterochromatin
Answer:
relaxed packaging of the chromatin and increased transcription.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.
Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.
