When you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very large molecules (thousands or even millions of nucleotides long), and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length). Which two classes of DNA do these different samples represent

Answers

Answer 1

Answer:

Leading strand and Okazaki fragments

Explanation:

The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.

The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.

This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.

The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

Scientists are able to reproduce certain plants and animals by cloning them in laboratories. The diagram shows the steps of cloning using tissue cultures. Do you think cloning is a form of asexual reproduction? Explain your answer using evidence from the diagram

Answers

Answer:

Yes.

Explanation:

Yes, cloning is a form of asexual reproduction because there is no fusion of sperm and eggs takes place. the animal which is formed from this process is identical of that organism because it is produced from the tissue of that single animal. in 1996, first mammal is produced from cloning was sheep named dolly at the Roslin Institute in Scotland. In cloning, the egg is taken from female organism and remove the nucleus from the egg then the desired organism cell is taken and fuse with the nucleus with the help of electricity. Then implant this embryo in the body of first organism from where egg is taken and after that the embryo turns into a baby, this process is called cloning.

Answer:

Yes, cloning is a form of asexual reproduction. The diagram shows that new plants form from a single parent plant, which means that the offspring are genetically identical to the parent.

If a cell has 24 pairs of chromosomes in its diploid state, how many
chromosomes will it have after Meiosis 2?
A. 12
B. 24
C.48
D. 6

Answers

Answer:

option A is correct that is 12

Explanation:

meiosis occur in two phases in first phase DNA replication occur and amount of DNA become doubled without any change in the chromosome number and two daughter cell (each 2 n)are formed.

now in stage 2 each daughter cell undergoes mitosis with the formation of two cells with half chromosomes(n)

now 2n=24

n=24/2 =12

after meiosis stage 1...........two daughter cell each with  24 chromosomes

stage 2 .............each daughter cell form two grand daughter cell each with 12 chromosomes

net result.......4 daughter cell each with 12  chromosome(assuming cell as a diploid cell)

If a cell has 24 chromosomes before cell division then the daughter cell resulting from the mitotic division will have 24 chromosomes while the daughter cell resulting from the meiotic division will contain 12 chromosomes each.

The answer is option A.

What are meiotic and mitotic cell divisions?

There are sorts of cell departments: mitosis and meiosis. most of the time whilst humans discuss “cellular division,” they suggest mitosis, the procedure of making new frame cells. Meiosis is the sort of cell division that creates egg and sperm cells. Mitosis is an essential technique for lifestyles.

What has a greater influence on protein levels? A. Protein degradation has a greater influence because they are denatured faster than the cell can produce them B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced C. mRNA destroyer concentration has a greater influence because mRNA is destroyed right after the proteins are produced D. Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from

Answers

Answer: b

Explanation: i got the answer wrong and i’m looking at the results rn

Protein is being produced with the help of a process called translation in which mRNA gets translated to produce proteins. The translation is followed after the process of transcription of DNA to RNA.

The cause of the greater influence of protein levels has defined as follows:

The destruction of mRNA could greatly influence protein levels as mRNA is considered the source for proteins to get synthesized. This is because if mRNA gets destroyed, proteins would not have been produced at all. Thus, directly influences the levels of protein.

Thus, we can conclude that mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced. Hence, option (b) is the correct answer.

added the same amount of tap water to one plant and the same amount of spring water to the

other. Describe an action that would best improve the reliability of their results?

Answers

Answer:

To improve the reliability of the results, the nutritional component of each category of water must be tested and recorded.

Second, the experiment should be carried out under greenhouse conditions.

The above actions will afford more control. When an experiment is controlled, it means that except for the dependent variable, all other variables are kept constant by the scientist.

By performing the experiment under greenhouse conditions, the kind of water the plants receive, temperature and other biotic actors are kept within measurable limits thus increasing the reliability of the results.

Match each hormone to its function
•luteinizing hormone
•testosterone
•oxytocin
•follicle-stimulating hormone
•estrogen
•gonadotropin-releasing hormone

Answers

Answer: Stimulates the contraction of the uterus during childbirth - OXYTOCIN

Stimulates sperm production and growth of ovarian follicles - FOLLICLE STIMULATING HORMONE

Initiates the Secretion of leutinizing hormone and follicle stimulating hormone - GONADOTROPIN RELEASING HORMONE

Initiates the development of secondary sex characteristics in females - ESTROGEN

Initiates the development of secondary sex characteristics in males - TESTOSTERONE

Initiates cell production of testosterone and estradiol by cells in the gonads - LUTEINIZING HORMONE.

The correct match for hormone and their functions are- 1- Oxytocin, 2- follicle-stimulating hormone, 3- a gonadotropin-releasing hormone, 4- estrogen, 5- testosterone, and 6- luteinizing hormone.

Oxytocin is a naturally occurring hormone that plays a vital role in the reproductive system of both men and women, including labor, delivery, and breastfeeding, as well as in human behavior.

FSH is produced by the pituitary, which is a small gland just below the brain. The pituitary plays a vital role in the development and regulation of sexual function.

Gonadotropin-releasing hormone stimulates the brain’s pituitary gland to produce and release the hormones LH and FSH.

Estrogen is a family of hormones that play a vital role in the reproductive and sexual development of women.

Testosterone is a male sex hormone. It is responsible for spermatogenesis and fertility in males.

Luteinizing hormones (LH) are hormones in the body that stimulate the reproductive system. Luteinizing hormone stimulates ovulation and stimulates the production of the hormones needed for pregnancy

Answers

Answer: Option C.

slight fluctuations that are kept within a narrow range.

Explanation:

An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).

Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.
