Answer:
The correct answer is B. A gamete carries one allele for a gene.
Explanation:
Gamete (also called sex cell or reproductive cell) is a haploid cell (having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to the Law of segregation given by Gregor Mendel-
During the process of gamete formation, the two alleles of each gene segregate from one another so that a gamete carries one allele for a gene.
Thus, option B) is the right answer.
Answer:
B.

Answer:
Ah ok. Sorry this is due to what its called, not what it is.
Explanation:
This is a table of the MRNA that is transcribed to make protiens.
The UCAG found on the graph are the different RNA bases.
A single base codes for a single part of a protien.
A codon is made up of 3 base pairs. A single codon codes for a protien.
So lets look at the first 3 bases - AUG
This looks like MET
So, let me show you how I found this:
The first base pair is A, looking at the left 4 letters, we see is the third row down.
The second base pair is U, looking at the top, we see is this first row.
Now we know its the third row down, and the first one to the left.
So now we have 4 possible protiens.
To find the exact one, use the third base pair, which is G. This is the bottom of the mini row found in the right side.
Doing this, we find that MET is the protien.
To be honest I dislike this table, so I will be using the one attached below.
Anyway, this MET protient removed option B.
Next we have Codon CUC
Looking at my graph below, I see that CUC codes for LEU.
This removes ooptions A and D, leaving C.
But now we need to check wether it is C or none of the above.
Again, I take codon AAG, and find lys. This is in anser C.
I take codon UGC, and find cys. This is in answer c.
Finally, I take codon UUC, and find PHe. This is answer c.
So C is your answer.
Hope this makes sense and helps!
I personally find my graph easier to use, and fi you agree, then I suggest you use it!

What is the value of y in the equation 5x + 2y = 20, when x = 0.3? 0 2.5 2.8 O 9.25 O 10.75
Answer:
O 9.25
Explanation:
The following mathematical equation is given in this question:
5x + 2y = 20
Using this equation, we're asked to find the value of y when x = 0.3. Hence, we substitute 0.3 for x in the equation as follows:
5x + 2y = 20
5 (0.3) + 2y = 20
1.5 + 2y = 20
Collect like terms
2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
y = 18.5/2
y = 9.25
Therefore, y = 9.25 when x = 0.3

O offspring with a variety of phenotypes
O offspring with little variation in phenotype
O offspring that closely resemble their parents
O offspring that are adapted to a specific environment
The last one
Explanation:

What is species?A species is an organism's fundamental unit of classification, taxonomic rank, and biodiversity. The biggest group of organisms in which any two individuals of the right sexes or mating types can conceive a fertile offspring, usually by sexual reproduction, is referred to as a species.
A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chronospecies idea.
There are between 8 and 8.7 million different species of eukaryotes, according to the most recent accurate estimate.
All species are given a two-part name, or "binomial," with the exception of viruses.
Therefore, Offspring that are adapted to a specific environment is the beneficial for the survival of a species.

What does a chromosome consist of?
A. Tightly wound DNA only.
B. Loosely dispersed DNA and proteins.
C. Tightly wound DNA and proteins.
D. Loosely dispersed DNA.
Answer:
C
Explanation:
So, there are 2 different forms that DNA can be found in.
The more common form, where the DNA is loosly scattered.
There is a less common form, however, only found during cell division, which is a compacted form. The DNA is tighly wound in this case.
In the case of chromosomes, DNA is tightly pakced, and not loose.
Now, do they are do they not have protiens?
Well, heres another question, how does the DNA get compacted?
It has to wrap around histone protiens.
The logn strands of DNA wrap around many histone protiens, until the full length of DNA has been compacted.
So to answer the question, yes, there are protiens found in chromosomes(specificly histone).
This means the answer must be C, since chrosomes are both tightly bound, and contain protein.

Explanation:
When performing the streak for isolation technique, your result is unexpected: There is only growth obtained in quadrant 1. The growth observed in quadrant 1 is as expected, heavy with no isolated colonies. However, no growth is visible in any other quadrants.
Which of the following errors could explain this unexpected result?
A) The loop did not cross into quadrant 1 when streaking quadrant 2
B) You forgot to flame the loop in between quadrants
C) All of the errors listed here could be responsible for this unexpected result
D) Not enough bacteria was obtained from the starting culture when streaking quadrant 1
Answer:
A) The loop did not cross into quadrant 1 when streaking quadrant 2
Explanation:
The streak for isolation technique is a method used to get isolated bacterial colonies. This technique consists of, in a petri dish with culture medium, where, with the help of an inoculation loop, the bacteria are scratched on one side of the dish. This side is called the first quadrant. This inoculation loop must then cross with the first quadrant and be dragged to the second quadrant, where new lines must be made. This allows a part of the bacteria from the first quadrant to be carried over to the second. The inoculation loop must cross the second quadrant again to inoculate the third quadrant, and so on.
In this case, we can see that for bacterial colonies to grow in all quadrants, it is essential that the loop crosses in the first quadrant to cross out the second quadrant. If not, only the first quadrant will have bacterial colonies.
Answer:
A) The loop did not cross into quadrant 1 when streaking quadrant 2
Explanation:
There are many different techniques to isolate bacteria populations. Using solid media such as agar, you can perform the streak for isolation technique.
What you want to do by using this technique is to get an isolated colony of the bacteria of interest. And to get it, you need to dilute a sample or inoculum of bacteria as much as possible by streaking it. Every time you do it, you take fewer amounts of cells from the original sample, separating them each time more, to the point of having only one single cell apart by a few millimeters from another cell. The isolated cell divides and forms a new pure colony.
So basically, you need to imaginary divide the agar plate into four quadrants.
You sterilize the loop carefully and take a sample of bacteria, trying to get the smallest amount of inoculum. You will apply the loop with the sample in quadrant one and spread it. You close the plate and turn it, placing the second quadrant in front of you. You sterilize the loop again on the flame and let it cool. You perform the same motion in quadrant two but carefully touching the edge of quadrant one, so you can take some of the cells that you have already spread on it. Once you spread quadrant two, you close the plate and turn it again, so quadrant three is in front of you. You sterilize the loop again on the flame and let it cool. You perform the same motion in quadrant three but carefully touching the edge of quadrant two. Close and rotate the plate. You sterilize the loop and repeat the same motion in the last quadrant. Close the plate and take it to incubation. Finally, you put the loop on the flame for the last time.The importance of extending the streaks into the anterior quadrant is to take a few cells from there and to spread them in the following quadrant. In this way, you are diluting the original inoculum, and separating the cells each time more. The fourth quadrant should have a few isolated cells that will reproduce and form a pure colony. If you do not touch the anterior quadrant while streaking, you will not have any cell in the quadrant, and you will not observe any colony after the incubation. The importance of sterilizing the loop every time you change the quadrant is to avoid contamination with other species. If you do not flame the loop, the result will be too many colonies of different species, probably touching themselves, in each quadrant.Es el nombre que se le da a un cuerpo celeste dentro de su trayectoria
