Your student is trying to create a "Gene X" knockout mouse by introducing a recombinant construct into embryonic stem (ES) cells, selecting transformants, and introducing the transformed cells into mouse blastocysts. He designed his construct as follows: NeoR region of homology to Gene X---HSV tk--- region of homology to Gene X where Neo is the neomycin-resistance gene and HSV tk is the Herpes Simplex virus thymidine kinase gene. He transforms the ES cells and exposes them to G418 and ganciclovir. Explain to your student why he failed to recover transformed ES cells. Choose the two correct statements. a. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be sensitive to ganciclovir and neomycin, and would die.
b. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be resistant to ganciclovir, but sensitive to neomycin, and would die.
c. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to ganciclovir, but resistant to neomycin, and would die.
d. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin and ganciclovir, and would die.
e. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin, but resistant to ganciclovir, and would die.

Explanation:

Approximately 55%of an adult female body weight is water if a woman body contains 38 kg of water what is the woman's total weight

Answers

Answer: 69kg

Explanation:

Let the total weight of the woman be represented by x. Based on the information given, we can derive an equation which will be:

55% of x = 38kg

55/100 × x = 38kg

0.55 × x = 38kg

0.55x = 38kg

Divide through by 0.55

x = 38kg/0.55

x = 69.09099

x = 69kg

Therefore, the woman's total weight is 69kg.

A. volume increases and density decreases

Explanation:

I got a 5 on mastery test thanks to some comments on original answer

Based on the graph, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.

What is the density-temperature relationship?

The density of a substance is defined as its mass per unit volume. In the case of water, the density varies with temperature, as shown in the graph. At 4°C, the density of water is about 1000 kg/[tex]m^3[/tex]. As the water is cooled, its density decreases, reaching a minimum of about 999.87 kg/[tex]m^3[/tex] at 3.98°C (this is the temperature at which water is most dense). As the water is cooled further, the density increases again, but it remains lower than it was at 4°C. The reason for this behavior can be explained by the way water molecules behave as they are cooled. At higher temperatures, the water molecules have more kinetic energy and are more spread out, resulting in a larger volume and lower density.

Hence, the density of water decreases as the temperature decreases from 4°C to 0°C. Therefore, a fixed mass of water will have a higher volume at 0°C than at 4°C.

The individuals that are the healthiest will always get more resources and survive better
O The individuals that survive better and reproduce more often will pass their traits on more often.
The strongest and fastest individuals will always survive and reproduce more often

Answers

Answer:

C

Explanation:

This is because the favorable traits will typically be present within the surviving animals leading them to be able to survive long enough and pass down more favorable traits.

Hope this helps!

The sentence that best explains the phrase "survival of the fittest" the individuals that are the healthiest will always get more resources and survive better.

Evolution by Natural selection

The theory of evolution was proposed by the scientist, Charles Darwin. He proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor.

Natural selection according to Charles Darwin was based on the fact that traits where inheritable. From his experiment, he concluded that:

some individuals will have inherited traits that help them survive and reproduce,

organisms with these traits leave more offspring, the traits will tend to become more common in the next generation.

These organisms with these helpful traits will become better adapted to it's environment.

Therefore, the individuals that are the healthiest will always get more resources and survive better.

Some years ago, before crude oil prices became an economic concern and an international political issue, a biologist proposed a curious-sounding plan.  He suggested that a portion of our crude oil supplies be converted directly into edible food, instead of distilling it to gasoline for the typical farming methods for raising food.
Before you become nauseated at the idea, you should know that this conversion has been done on a trial basis.  Making edible, non-toxic food from petroleum is feasible.  Also, considering that the components of fossil fuels were once ordinary plants and animals in an ordinary food chain, maybe there is some logic in his plan.  What does crude oil amount to, anyway, but dinosaur fat? (No, really it is primarily formed from microscopic organisms.)
It might be the right time to form a new corporation and market a new product.  What shall we call it…”DinoSnack,” maybe?  With interest in dinosaurs as high as it is, how can we go wrong?
Your task is to evaluate this suggestion, allowing for both pro and con, the positive and the negative aspects of it.   Surely there will be economic and political considerations, but concentrate especially on the biological, ecological factors.

Which type of cell division causes a puppy to grow into an adult dog?
meiosis
mitosis
eukaryotic
O homeostasis

Answers

Answer is mitosis

Meiosis is for sexual reproduction and for producing offspring, whereas mitosis is the cell division for cell reproduction so it has to be mitosis as it is the cause of cell growth, allowing the puppy to grow into an adult dog

It wouldn't be eukaryotic or homeostasis since they're not types of cell division.

Mitosis is the kind of cell division which allows a puppy to develop into an adult dog. So, the correct option is B.

What is Mitosis?

In eukaryotic cells, a process called mitosis produces two daughter cells, each of which has the same amount of chromosomes as the parent cell. Multicellular organisms, like dogs, go through a process called mitosis during which cells divide and differentiate into different cell types.

The process of meiosis, on the other hand, produces gametes with half as many chromosomes as the parent cell and is only able to occur in specialised cells, such as the ones involved in sexual reproduction. Contrarily, homeostasis has nothing to do with cell division and instead refers to the preservation of a constant internal environment within an organism.

Therefore, the correct option is B.

1. DNA

2.A , G , C and T

3.The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.

4.Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.

5.Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.

6. 1869

7.The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.

8. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.

9. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.

10. 20

11. A group of disorders that cause red blood cells to become misshapen and break down.

With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis).

12. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).

13. The Human Genome Project was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint.
