During the 1950s, a scientist named Lysenko tried to solve the food shortages in the Soviet Union by breeding wheat that could grow in Siberia. He theorized that if individual wheat plants were exposed to cold, they would develop additional cold tolerance and pass it to their offspring. Based on the ideas of artificial and natural selection, do you think this project worked as planned
Answers
Answer:
No
Explanation:
Trofim Lysenko was a Biologist in the then Soviet Union, who did not believe in the fundamental laws of science. Selective breeding is the method developed by humans to change certain characteristics of species to desired outcomes. This is based on the fact that living things have inheritable traits encoded in genes that can be passed from one generation to another.
Lysenko did not believe in this fact. He rather believed that when exposed to the right environment, plants and animals soon become adjusted to the exposure and can then develop traits that would be passed on to their offsprings. He applied this theory of his when he exposed wheat plants to cold believing that they would develop tolerance to cold. This failed woefully and resulted in severe starvation that caused the death of millions of people in the Soviet Union.
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.

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.

When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? Two diverged populations are capable of mating and producing viable and fertile offspring. Hybrid individuals may have reduced fitness and thus be strongly selected against. Hybrid individuals are always allopolyploid and are thus unable to mate with either of the original species. One species has a selective advantage, so as hybridization continues, the other species will go extinct.
Answers
Answer:
Two diverged populations are capable of mating and producing viable and fertile offspring.
Explanation:
Although the biological concept of species says that two different species can not mate and produce viable fertile descendants, the hybrid zones are characterized for being an area where two different genetically groups meet and reproduce. These groups might be the same or different species.
This is a frequent phenomenon in nature, and widely common geographically and among taxonomic groups. It is not rear that different sympatric populations, with a short time of divergence and similar reproductive strategies, can hybridize and even generate new populations that get reproductively isolated from their parentals.
When talking about sympatry we refer to two similar species that coincide in part or their whole distribution area.
These new populations are even morphologically different from the parental forms, which allow them to colonize new habitats and niches, promoting diversification.
Hibridation zones are very important to conserve, just because they are points of genetic diversity generation and diversification areas.
When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals can form. This is possible because hybrid individuals are always allopolyploid and therefore are unable to mate with any of the original species, to understand more we need to know that......
Hybrid animalsHybridization, that is, the process through which different species reproduce, generating an offspring, is not considered a very common phenomenon in nature. This is because, in general, species have a distinct number of chromosomes, the cell structures that contain genes. These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male are necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies. However, in some cases, even with the lack of chromosome pairs, reproduction between different species is successful, generating the hybrid. However, the birth of the individual does not mean that its survival is guaranteed. Often, the hybrid generated is weaker than its parents and does not survive; in other cases, the hybrid can adapt better to the environment than the species that conceived it.
With this information, we can conclude that hybrid animals are a cross between two different species, but this hybrid can have several complications for its survival.

Explanation:
Nitrogenous bases are used to construct nucleotides. Until the discovery of the helical shape of the DNA molecule, were only possible to identify the genetic material (chromosomes) by the microscope. Chromosomes are composed of DNA and proteins (histones). Nucleotides are the building blocks of the DNA molecule. The X-ray diffraction data obtained by Rosalind Franklin were used to decipher the DNA structure. The ball-and-stick is a molecular model where atoms are represented by spheres and bonds are represented by rods. Chargaff's rules indicate that the content of cytosine is equal to guanine and adenine is equal to thymine. Rosalind Franklin died of ovarian cancer in 1958. The double-stranded DNA molecule must be unwound and then the DNA strands serve as templates to synthesize identical DNA molecules.

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.

The information is preserved because DNA codes for RNA, which codes for protein. Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C. Genetic information is preserved by base pairing between A and T and between G and C across the two strands of the double helix. The information in DNA is copied into RNA, which is used as a template to copy back to DNA.

Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C.
Explanation:
Deoxyribonucleic acid contains genetic information in the bases i.e the Nitrogenous bases Adenine, thymine, Guanine, cytosine are the store for coding genetic information, in them lies the genetic information of an organism. Each base is coding for different gene the is found in the organism.
After the information on the DNA have been moved to an intermediary Ribonucleic acid (RNA) it is been translated into an amino acid a building block of protein containing all the genetic information coded for by the Nitrogenous base.
