The correct sequence of events that occurs during protein synthesis? A
Explanation:
2. DNA is used as a template to create mRNA, which leaves the nucleus
4. mRNA molecule binds to a ribosome
1. tRNA brings the correct amino acid specified by the mRNA codon
3. Amino acids are bonded together to make a polypeptide (protein)
5. The ribosome releases both the mRNA molecule and the polypeptide (protein)
During protein synthesis, all the machinery for synthesis occurs in a sequential manner and the first need is a DNA template, so the correct option is a.
What events occur during protein synthesis?Protein synthesis occurs in the ribosomal machinery and the process is called translation and starts after transcription.
DNA acts as a template for transcription and makes mRNA which translates into protein. mRNA act as a messenger for protein synthesis, this mRNA converts into protein with the help of ribosomal machinery.
In the process tRNA act as an adapter molecule adding an amino acid to the protein chain according to the codon on mRNA. In the last step protein and mRNA are released by the ribosome.
Therefore protein synthesis starts with DNA, hence option a is correct.

How does the human immune system work
Answer:
The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body.

Answer:
This is a personal question.
Explanation:
what is the approximate percentage of total fixed nitrogen attributed to human activities?
Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

what will be the result if a eukaryotic cell completes mitosis but does not undergo cytokinesis?
A cell that completed mitosis but does not undergo cytokinesis PRODUCES one cell with two nuclei, each identical to the nucleus of the parent cell. Cytokinesis is the last phase of cell division.
Cytokinesis is the process by which a parental cell divides its cytoplasm to produce two genetically identical daughter cells, each one containing one cell nucleus.
Cytokinesis occurs in both types of cell division, i.e., mitosis and meiosis.
In animal cells, cytokinesis occurs by the emergence of a contractile ring that appears just beneath the cell membrane.

An example of a communicable disease is
A - cancer.
B - chronic respiratory disease.
C- diabetes.
D -giardiasis.
Answer:
D giardiasis is the correct answer :)
An example of a communicable disease is giardiasis, which is in option D. Giardiasis is an example of a communicable disease. It is caused by a microscopic parasite called Giardia lamblia.
This disease affects the digestive system, causing symptoms such as diarrhea, abdominal cramps, bloating, and nausea. It is typically transmitted through the ingestion of contaminated food or water that has been contaminated with the parasite. Chronic respiratory disease includes conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis, which are usually caused by long-term exposure to irritants or genetics and are not directly communicable.

when two strains of bacteria with genotypes abcd and abcd are grown together in the lab, a small number of bacteria with the genotype abcd eventually arise. how does this likely occur?
Answer:
These enzymes work in two ways. Some are pre-replicative and search the DNA for nucleotides with unusual structures
Explanation:
This happened through a lateral transfer of genes.
We can arrive at this answer because:
Lateral gene transfer is a system for exchanging genetic material between unrelated bacteria.Bacteria are beings that reproduce without the exchange of genetic material, but in some cases, this can be done with the lateral transmission of genes.This transmission can be done through the process of conjugation, translation, or transformation.The result is that new bacteria are created with a mixture of genes from two unrelated bacteria.

how do I write the equation P^2 = kA^3, so that I'm solving for the variable K?
Answer:
k = (P^2)/(A^3)
Explanation:
Step 1: Flip the equation.
[tex]kA^3 = P^2[/tex]Step 2: Divide both sides by A^3.
[tex]\frac{kA^3}{A^3} = \frac{P^2}{A^3}[/tex] [tex]k = \frac{P^2}{A^3}[/tex]Therefore, the answer is [tex]k = \frac{P^2}{A^3}[/tex].
If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?
Answer:3/13
Explanation:
Answer:
x = 1/2 and x = -7
Explanation:
you need to factor
multiply 2 x -7 to get -14
then find factors of -14 that add to give you 13
14 and -1 work
now rewrite the original equation but replace 13x with 14x - 1x
so 2x^2 + 14x - 1x -7 = 0
now factor by grouping
(2x^2 + 14x) (-1x - 7) = 0
factor the greatest common factor out of each group
2x(x + 7) -1(x + 7) = 0
the factors are (2x - 1) (x + 7) = 0
set each factor equal to zero and solve both for x
2x - 1 = 0 x + 7 = 0
+1 +1 - 7 - 7
2x = 1 x = -7
÷2 ÷2
x = 1/2

Explanation:
Water molecules moving across the plasma membrane until solute concentrations are equal on both sides of the membrane best describes the process of osmosis in an animal cell .
Osmosis is the process in which molecules move from a region of higher concentration to that of a lower concentration across a semi-permeable membrane.
Osmosis provides a balance between the elements in which organisms are exposed to. A very high concentration may cause cells to shrink and die hence the reason to maintain a balance for optimal functions and survival.

C) Water condensing on the side of a water bottle:
Answer:
Explain how kinetic energy affects each object as it changes its state of matter:
A) Water boiling:
B) Popsicle freezing:
C) Water condensing on the side of a water bottle:
Explanation:
A) A water boiling will result in evaporation, therefore the particles will move extensively faster than liquid due to it being vapor.
B) A popsicle freezing is originally a solid so it'll have the least amount of kinetic energy as the particles remain fairly slow.
C) Due to the fact that water is condensing, while turning into a liquid. The water condensing on the side of the water bottle would produce a lower kinetic energy level due to the fact that it's becoming a liquid. Though liquids have higher kinetic energy than solids, as gases have a higher kinetic energy compared to liquids.
Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
What is Kinetic energy?A popsicle is initially a solid, it will have the least kinetic energy because the particles are still moving slowly. Because water is condensing as it transforms into a liquid.
Because it is turning into a liquid, the water that is condensing on the water bottle's side would have less kinetic energy.
Gases have a higher kinetic energy than liquids, despite the fact that liquids have a higher kinetic energy than solids.
Therefore, Evaporation from boiling water causes the particles to move much more quickly than they would in a liquid state.
