How does the process of gel electrophoresis produce DNA fingerprints? An electric current sorts DNA nucleotides according to their bases. O An electric current cuts a DNA strand into segments of various lengths O An electric current causes segments of DNA to move at different rates O An electric current supplies a charge to uncharged segments of DNA
Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

How many atoms does the formula Mg3(PO4)2 have?
Answer: time all the number together and you will got it.
Explanation:
The concentration of the solute in the solution is lower than the concentration inside the cell
When a cell is placed in this solution, more water enters the cell than it leaves it
The concentration of the solute in the solution is higher than the concentration inside the cell
The concentration of the solute in the solution is the same as in the cell
Causes water to move across the cell membrane
Causes a cell to swell
When a cell is placed in this solution, more water will leave the cell than it enters it
Doesn’t change the shape of a cell as the same amount of water enters and leaves the cell

What are some advantages of asexual reproduction when compared to sexual reproduction? (In your own words please for brainliest!!)
Answer And Explanation:
The advantages of asexual reproduction compared to sexual reproduction include the population being able to increase rapidly when the conditions are in their favour, only one parent is needed, it is more time and energy-efficient due to not needing a mate and it is faster than sexual reproduction.

The children in a middle school classroom are all exposed to chicken pox one week. Among these students are John, who had chicken pox when he was much younger, and Sara, who has never had chicken pox. Which student do you expect would be less likely to become ill with chicken pox following this exposure and why? (5 points) John: he has naturally acquired active immunity to chicken pox from his previous exposure. Sara: she has naturally acquired passive immunity to chicken pox from exposure to other students. John: the pathogens that cause chicken pox will no longer be able to enter his body. Sara: since she has not suffered from chicken pox, her immune system is probably stronger than Johns.
Answer:
John: he has naturally acquired active immunity to chicken pox from previous exposure.
Explanation:
Your body naturally has some immunity to things that aren't you, but when you get sick with a specific pathogen, your body begins to make antibodies that specifically recognize that pathogen. Each antibody only recognizes one pathogen, and it floats around waiting to find it again so it can tell your body to kill it before you get sick again. This is why we become immune to chicken pox; after the first time you beat it, your body has the labeled antibodies and it can quickly destroy the pathogen before you get sick again.
Answer:
John: he has naturally acquired active immunity to chicken pox from his previous exposure.

2. When calculating the recombinant frequency of two genes, what is
the most important factor?
O A. how close they are to each other
OB. how close they are to the end of the chromosome
Oc. whether they are on the X or Y chromosome
OD. which one is higher on the chromosome
Answer:
A
Explanation:
The most important factor is how close they are to each other.
• The physical swapping of the pieces of chromosomes at the time of meiosis is responsible for the recombination of genes.
• The swapping can take place anywhere along the length of the chromosome, that is, in any part of the gene.
• The recombination frequency between the two genes is equivalent to the ratio of offspring in which the event of recombination took place between the two genes at the time of meiosis.
• The determination of the recombination frequency is done by the frequency of the recombination events between the two genes in meiosis.
• The more the physical distance between the two genes, the more is the probability that the recombination take place during any meiosis event.
Thus, the correct answer is option A.

Scientist observed an organism X and noted down the mode of nutrition as follows X secretes enzymes outside its body and digests food with these enzymes. It then absorbs the digested food. Which organism was observed by the scientist?
Answer:
Hydra
Explanation:
The mode of nutrition being described in this question is EXTRACELLULAR DIGESTION, in which a food substance is chemically broken down externally. The organisms being portrayed is HYDRA. Hydra is an animal that secretes digestive enzymes that work on the food extracellularly (outside the organism), then absorb the digested food.
Therefore, the organism X observed by the scientist whose mode of nutrition is to secrete enzymes outside its body and digests food with these enzymes, then absorbs the digested food is the HYDRA.

Describe how the genetic code found in DNA bases is used to synthesize a polypeptide chain.
Answer:
The genome of an organism is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid.

BRAINLIEST!!! How is glucose related to carbohydrates?
Answer:
When carbohydrates are digested and sent into the blood stream they become sugars called glucose. Glucose provides energy for all of your cells. If not all of the glucose is used immediately, your body will store it in your muscles and liver as glycogen. Glucose is a type of sugar found in food.

In Rabbits, black fur (B) is dominant to white (b), and long ears (E) are dominant to short ears (e). What is the expected phenotypic ratio of the offspring of a BBee x bbEE cross if these alleles sort independently?
Answer:
A. 16 black/long ears, 0 black/short ears, 0 White/long ears, 0 White/short ears
Explanation:
This question is a typical dihybrid cross i.e. involving two genes in rabbits. One coding for fur color and the other for ear length. The allele for black fur (B) is dominant to allele for white fur (b) and allele for long ear (E) is dominant to alelle for short ear (e).
In this question, a cross between two rabbits with genotypes: BBee x bbEE is performed. The following combination of gametes will be produced by each rabbit:
BBee - Be, Be, Be, and Be
bbEE - bE, bE, bE, and bE
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
All BbEe offsprings, which have a black fur and long ear phenotype.
Hence, the phenotypic ratio is 16 black/long ears, 0 black/short ears, 0 White/long ears, 0 White/short ears
Plant cells have a square shape

which two body systems interact to expel the waste product carbon dioxide
a urinary system
b nervous system
c excretory system
d circulatory system
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
