DNA is considered the blueprint of life, yet in eukaryotic organisms, such as humans, DNA never leaves the nucleus. Which of the following is the best explanation for how DNA codes into physical traits and characteristics, even though it never enters the cytoplasm?
Answers
Answer:
The first one
Explanation:
This is just Central Dogma. DNA (deoxyribonucleic acid) is transcripted into mRNA which goes to the Ribosomes where it is turned into polypeptides/protiens which code the body.
DNA is a molecule made up of Deoxyribonucleic acid that is composed of two chains that coils are around themselves and form the double helix.
Within eukaryotic cells, DNA is organized into a strong structure called as chromosomes. These are duplicated in the cell formation process. Most organisms store their DNA in the cell nucleus. DNA is a long polymer made of repeating units. DNA is capable of coiling into tight loops and other shapes. As the genetic information is held within genes the genome encodes protein. Thus the DNA is a nucleus and can be transcribed in the mRNA which later eaves the nucleus and forms proteins. Hence the option A is correct.Learn more about the DNA is considered the blueprint of life yet in eukaryotic organisms.

As part of a laboratory experiment in his psychology course, Miguel is observing the activity of a recording electrode on the axon of a neuron. As an action potential
occurs what might Miguel observe?
A The axon will release neurotransmitters into the synapse.
B. The avon will remain at threshold potential as negative ions continue to flood the cell.
OC The decial charge of the neuron will go from positive to negative before returning to threshold potential.
OD. The curical charge of the neuron will go from negative to positive before returning to resting potential
Answers
Answer:
The correct answer is D
Explanation:
A resting neuron has a voltage across its membrane, which is referred to as resting potential. This resting potential is caused by concentration gradients of ions across the membrane. A neuron returns to the threshold potential by the movement of positive ions (especially K+ ions) through channels that stay open to exit the neuron.

An example of mitosis at work is a leaf
turning yellow.
growing.
taking in carbon dioxide.
performing photosynthesis.
Answers
The right answer is Growing.
Mitosis is the cell division that allows an equal distribution of genetic information from an initial mother cell to two daughter cells while retaining the karyotype over the cell generations.
Mitosis will ensure - sometimes unfortunately - the good fulfillment of several phenomena:
1. embryonic development,
2. the general growth of organisms from birth to adult size,
3. the continued growth of certain organisms and / or organs; for example, trees, hair, teeth in ruminants, nails, ...
4. to renew dead cells; for example skin cells, red blood cells, ...
5. to ensure healing,
6. to preserve cellular identity during the development and renewal of cells belonging to the same organs, tissues, ...
7. As a result of disorders: cancers
An example of mitosis at work is growth. Therefore, option (B) is correct.
What is mitosis?Mitosis is the process of cell division where one cell divides into two identical daughter cells. Growth involves an increase in the number of cells and therefore, mitosis is essential for the growth of living organisms. During mitosis, the cell's nucleus divides into two identical nuclei, and then the cell splits into two daughter cells, each with a complete set of genetic material.
This process is essential for tissue repair, renewal, and growth in multicellular organisms. While photosynthesis and the uptake of carbon dioxide are important processes that occur in plant cells, they do not directly involve mitosis. Leaf turning yellow is an example of the aging process and does not involve mitosis.

what is the difference between autosomes and gametes
Answers
Answer:
An autosome is any of the chromosomes, except the sex chromosomes, while is the sex cell.
Explanation:
Humans have 22 pairs of autosomes and one pair of sex chromosomes (pair number 23, made up of two X chromosomes in women and one X and one Y chromosome in men). Autosomes are numbered according to their relative size.
Gametes are the sex cells of multicellular and human organisms. They are haploid cells (that is, they contain 23 chromosomes, n), they originate by meiosis from germ cells (they contain 46 chromosomes, 2n).
During this process, germ cells mature and change shape until they become future gametes or cells with fertilizing capacity.

They need to be broken apart into individual atoms and rebuilt through RNA translation.
Explanation:
To form an amino acid the individual elements needs to be joined together to form a compound.
An amino acid is made up of nitrogenous bases they are joined together to form codon and are translated to amino acid
The process of translation in deoxyribonucleic (DNA) acid helps to translate the bases into an amino acid. This amino acids are said to be the buildings blocks of protein they perform specific function in the body system.

Answers
Answer:
One of them is the variance of the gene pool--in other words, the genetic adaptations plants and animals have help them to survive. That is where the phrase "survival of the fittest" comes from; if one is not genetically fit to survive in their environment, they will die off and their genes will not be added to the gene pool, making it easier for organisms with more fit genes to reproduce and add to the gene pool.
Another is the availability of resources. It is very hard for an organism to survive without food, water, and shelter. If the organisms of a species live in an environment with a lack of resources, they will die off, thus making them unable to reproduce and therefore go extinct.
Also, the presence of predators makes it difficult for a species to survive. Predators preying on prey make prey poulations go down and predator populations go up. However, going back to the gene pool, many organisms have adapted to hiding from predators with means such as camouflage or burrowing.
Finally, the general conditions of their environment. This one is self-explanatory. For example, you would not expect to find a polar bear in the desert or a cactus in the Arctic. The conditions are simply not right for their survival and they will die off. This is also why birds migrate--they need to go somewhere warm in the winter to keep themselves warm!

Explanation:
Acetylcholine is found in the synapse between muscles cells and neurons. It can be broken down by the enzyme acetylcholinesterase. Which of the following describes what happens if acetylcholinesterase is inhibited?
Acetylcholine will continue to be activated.
Acetylcholine will be prematurely terminated.
Acetylcholine will lose specificity of the response.
Acetylcholine will be inhibited.
Answers
Answer:
Acetylcholine will continue to be activated.
Explanation:
When we inhibit acetylcholinesterase with an acetylcholinesterase inhibitor (AChEI) it will inhibit acetylcholinesterase from breaking down acetylcholine into choline and acetate. This will increase the level and the duration of the neurotransmitter in the CNS, autonomic ganglia, and neuromuscular junctions.
