A cell is grown in a medium with radioactive amino acids for five minutes. The radioactive amino acids are able to be transported into the cell and assimilated into the proteins that are being assembled. After the cells are removed from the radioactive culture, the level of radioactivity is monitored at different time points. It is found that the area of the cell with the highest radioactivity after five minutes is the ribosomes on the rough endoplasmic reticulum. As time progresses, which statement best explains where the level of radioactivity will be highest in the next five minutes?
A) The radioactivity will be highest in the mitochondria, as the proteins made by the cell will need to be modified using ATP.
Eliminate
B) The radioactivity will be highest in the nucleus as the proteins made at the ribosome will be shipped to the nucleus to replicate the DNA.
C) The radioactivity will be the highest outside of the cell because the endoplasmic reticulum transports proteins directly to and through the cell membrane.
D) The radioactivity will be highest in the Golgi apparatus, as proteins made on the rough endoplasmic reticulum are transported to the packaging center prior to leaving the cell.
Answer:
It’s D ,I got it right on USAtestprep
Explanation:
The correct option for this answer is D, which signifies that the radioactivity will be highest in the Golgi apparatus, as proteins made on the rough endoplasmic reticulum are transported to the packaging center prior to leaving the cell.
What do you mean by Radioactivity?Radioactivity may be defined as a spontaneous process that involves the emission of radiation in the form of particles or high-energy photons resulting from a nuclear reaction.
The path of protein transport determines the level of radioactivity in this experiment.
First, the radioactivity is found highest in the ribosomes of ER, then the proteins are transported to the region of the Golgi apparatus by an anograde pathway and reflect in radioactivity.
Therefore, it is well described above.

if a bacterial cell is capable of taking up foreign dna, it is said to be what?
Answer:
competent
Explanation:
The uptake of foreign DNA from the environment is known as transformation
If a bacterial cell is capable of taking up foreign DNA, it is said to be competent.
What is competent?
Transformation is the process by which bacteria can absorb foreign DNA. In DNA cloning, transformation is a crucial step. After restriction digest and ligation, it takes place and transmits freshly created plasmids to bacteria.
Bacteria are chosen on antibiotic plates after transformation. Bacteria are extraordinarily adaptable creatures, with the rare capacity to take in and replicate (or copy) foreign DNA.
They gain an evolutionary advantage from this and are better able to withstand environmental changes. Bacteria, for instance, can acquire DNA that renders them immune to antibiotics.
Therefore, the term is competent for a bacterium that is capable of taking up foreign DNA.

go keilani
A protein that speeds up a biological and chemical reaction to build and split any molecule is called an enzyme. They are produced naturally in the body.
The correct answer is:
Option C. have a complementary shape to the substrate.
This can be explained as:
If the active site on the enzyme is occupied by an inhibitor then the substrate will not be able to bind and the reaction will not occur.Activation energy is the minimum amount of energy needed for the reaction.If the enzyme is destroyed then no reaction will occur as the active site is present on the enzyme surfaces.Therefore, the active site should have a complementary shape to the substrate.

How can the reliability of the investigation be improved?
Answer:
You can test reliability through repetition. The more similar repeated measurements are, the more reliable the results. The reliability of single measurements is not improved through repetition, but through the design of the experiment. Implementing a method that reduces random errors will improve reliability.

Photosynthesis Virtual Lab
Summarize the results and provide an explanation or reasoning for what was observed. How does light color affect the rate of photosynthesis? Why does the color of light matter?
Answer:
The lights higher on the light spectrum, like blue would have the fastest rate of photosynthesis because the energy is the highest. the green light would have the slowest rate because the chlorophyll inside of the leaves reflects green light, so it would not be absorbed as mich as the other colors. The color matters because the color or wavelength of light does affect photosynthesis, which is how plants can create their own food.

a) An F1 x F1 self-fertilization gives a 9:7 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?
b) An F1 x F1 self-fertilization gives a 9:3:4 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?
c) An F1 x F1 self-fertilization gives a 15:1 phenotypic ratio in the F2. What phenotypic ratio would you expect if you test-crossed the F1?
According to the gene interaction that is operating in the trait determination, the phenotypic ratios of the progeny produced when test-crossing a dihybrid are: a) 4:12, b) 8:8, and c) 12:4
-------------------------
To answer these questions, the first thing you should notice by looking at the phenotypic ratios provided, is that there are two genes involved in the trait, and there is interaction between them.
Let us assume diallelic genes. A and B are the dominant alleles, while a and b are the recessive alleles.
In the three cases (a, b, and c), F1 individuals are dihybrid. Their genotype is AaBb.
Observing the altered phenotype proportions of the offspring can reveal which interaction is operating in the trait determination.
We can use the phenotypic ratio to determine the interaction, so:
9:3:3:1 ⇒ No interaction9:7 ⇒ Double Recessive epistasis 9:3:4 ⇒ Recessive epistasis15:1 ⇒ Dominant duplicate genes.When talking about epistasis, we are referring to an interruption.
The epistatic gene can alter, influence, or suppress the expression of a hypostatic gene.
When there is only one epistatic gene in h0m0zyg0us recessive state, the interaction is known as recessive epistasis. This gene supresses the expression of the other gene. Phenotypic ratio 9:3:4.In double recessive epistasis, both genes are epistatic when they are in a h0m0zyg0us recessive state. This is, in the h0m0zyg0us recessive state, either of the genes will inhibit the expression of the other gene. And vice-versa. Phenotypic ratio 9:7.In Duplicate gene action, there are two genes involved in the expression of a phenotype, and the presence of at least one dominant allele is enough to produce the dominant phenotype. Phenotypic ratio 15:1.
So now, let us make the test-cross.
Note: You will see that the cross is the same in the three cases, but the phenotypic ratio changes according to the interaction.
Cross) dihybrid individual with h0m0zyg0us recessive one
Parental) AaBb x aabb
Gametes) AB, Ab, aB, ab ab, ab, ab, ab
Punnett square) AB Ab aB ab
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
F2) Phenotypic ratio
***Double recessive epistasis ⇒ 4:12
4/16 dihybrids12/16 heter0zyg0us for one gene and h0m0zyg0us recessive for the other gene.Both genes in recessive state inhibit the expression of the trait.
***Recessive epistasis ⇒ 8:8
In h0m0zyg0us recessive state, Gene A inhibits the expression of B.
8/16 AaBb or Aabb → The trait coded by B or b is being expressed8/16 aaBb or aabb → The trait coded by B or b is inhibited by aa.***Duplicate gene action ⇒ 12:4
Only one dominant allele, either A or B, is enough to express the trait.
12/16 AbBb, Aabb, or aaBb 4/16 aabb → No dominant allele, no trait expressed.Phenotypic ratios:
a) 4:12 = 1:3
b) 8:8 = 1:1
c) 12:4 = 3:1
