How are amino acids assembled during translation? explain the process of transcription
Answer:
During translation,ribosomal subunits assemble together like a sandwhich on the strand of mrna where they proceed to attract trna molecules tethered to amino acids a long chain of amino acids emerges as ribosome decodes the mrna sequence into polypepide or a new protein.
Transcription, the synthesis of RNA from DNA. Genetic information flows from DNA into protein, the substance that gives an organism its form. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein).
Answer:
Amino acid leads through a chain protein that makes its way into the Ribosome-(in the large subunit)
Explanation:
Check your understanding. What did you include in your response? Check all that apply.
mRNA attaches to the ribosome.
tRNA molecules transport amino acids to the ribosome.
Anti-codons and codons match up and form complementary base pairs.
Peptide bonds form between adjacent amino acids to form the protein.
Just pick all of them xD its not a wrong or right question

Which of these describes one way that the human nervous system maintains a constant body temperature when the external temperature is cold?
A. The Nervous system increases perspiration
B. The nervous system causes digestion to speed up
C. The nervous system causes bloods vessels to construct
D.The nervous system triggers the flight-or-flight response
Answer:
A
Explanation:
Nerves trigger sweat glands to release fluid that evaporates and cools the skin. Conversely, a drop in core temperature makes blood vessels constrict to conserve heat. The nervous system also triggers muscles to shiver to generate heat and warm the body.Apr 15, 2018
The nervous system causes blood vessels to constrict. Therefore, option (C) is correct.
What is nervous system?When the external temperature is cold, the human nervous system works to maintain a constant body temperature through a process called thermoregulation. One way this is achieved is by causing blood vessels near the skin to constrict, reducing blood flow to the skin and helping to retain heat within the body's core. This response is known as vasoconstriction.
Vasoconstriction is controlled by the sympathetic nervous system, which is part of the autonomic nervous system. This system is responsible for controlling involuntary bodily functions, including heart rate, blood pressure, and body temperature. When the body's core temperature drops, the sympathetic nervous system activates and causes the blood vessels to constrict, helping to maintain a constant internal temperature.
Increasing perspiration (A) can help to cool the body down in hot conditions, but it is not a mechanism for maintaining body temperature in cold conditions. Digestion speeding up (B) and the flight-or-flight response (D) are not directly related to temperature regulation.

The Hardy-Weinberg equilibrium can be useful to discover the presence of evolutionary forces acting on a given population. It is used in population genetics.
What is the Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium is a theory stat states that genotypic and allele frequencies will remain constant in a population in absence of different evolutionary forces.
These evolutionary forces include mutation, natural selection, migration and sample size.
The Hardy-Weinberg equilibrium may result useful for finding the causes that originated a change in allele and genotypic frequencies in a given population.

A cow's diet consists of grasses and grains. They do not eat other animals to survive. What kind of an animal is a cow? (A. carnivore) (B. decomposer) (C. herbivore) (D. omnivore)
Answer:
C. Herbivore
Explanation:
Answer:
C. herbivore
Explanation:
A herbivore is an organism that eats plants such as grasses and grains. A carnivore eats other animals to survive so its not a carnivore. An omnivore eats both like people so since omnivores also eat meat, it's not that either. And lastly, A decomposer breaks down organic material such as mushrooms. Therefore, a cow is a herbivore.
