Answer: X-rays
double helix
Wilkins and Franklin studied the structure of DNA using X-rays, a technique to examine molecules, and helped Watson and Crick determined that the shape of the molecule was a double helix.
What are the functions of DNA?Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins.
DNA is essential for inheritance, coding for proteins, and providing instructions for life and its processes. DNA dictates how a human or animal develops and reproduces, and eventually dies.

Armadillos have 32 pairs of chromosomes
18. What is the diploid number (2n) for the somatic cells of armadillos?
19. How many chromosomes are present at the beginning of mitosis in an armadillo cell?
20. How many chromosomes are present in each daughter cell at the end of mitosis?
If Armadillos have 32 pairs of chromosomes;
The diploid number (2n) for the somatic cells of armadillos is 64There will be 64 chromosomes at the beginning of mitosis in an armadillo cell. There will be 64 chromosomes in each daughter cell at the end of mitosis.MITOSIS:
Mitosis is the process by which a single cell produces two daughter cells that are genetically identical to one another. Mitosis results in daughter cells that possess the same number of chromosomes as the parent cell.This means that if Armadillos have 32 pairs of chromosomes i.e 64 chromosomes. The following applies:

Answer give in Nepali How carbon dioxide is necessary for photosynthesis
Answer:
❤----------------------------------------------------------------------------------------------------------❤
Carbon dioxide is necessary for photosynthesis in plants. It is so necessary because it combines with water to form glucose or carbohydrates which are incredibly important for plants to provide energy. If they were to not take in carbon dioxide, then they would also not give oxygen which is the most essential for humans.

A. tRNA delivers DNA code to the ribosome and mRNA delivers amino acids to the ribosome
B. mRNA delivers DNA code to the ribosome and tRNA delivers amino acids to the ribosome
C. tRNA delivers DNA code to the nucleus and mRNA delivers proteins to the ribosome
D. mRNA delivers DNA code to the nucleus and tRNA delivers proteins to the ribosome
Answer:
The right answer is D.
Explanation:
The messenger ribonucleic acid, messenger RNA, or mRNA is a transient copy of a portion of the DNA corresponding to one or more genes. mRNA is used as an intermediate by cells for protein synthesis. Jacques Monod, François Jacob, and their collaborators issued and showed the concept of messenger RNA in 1960.

A. Identify two examples of environmental factors that may impact myeloperoxidase activity. Describe how each of the environmental factors would affect the reaction tare of an enzyme.
B. Predict the how researchers can use myeloperoxidase activity as oxidative stress biomarkers in patients with rheumatoid arthritis. Provide reasoning to justify your prediction.
Answer:
So... MPO is most abundantly expressed in neutrophil granulocytes, and produces hypohalous acids to carry out their antimicrobial activity through oxidative damage during the respiratory burst. It requires heme as a cofactor.
Regarding environmental factors ... obviously the first factor is the presence of an infection and inflammation that cause an increase in the activity and production of MPO. Second, alterations in the MPO gene cause its congenital deficiency which predispose to infections.
Rheumatoid arthritis is an autoimmune and autoinflammatory rheumatoid disease in which significant joint damage is observed. In the joint capsule, inflamed infiltrates are observed composed of neutrophils and lymphocytes. Measurement of MPO levels in the joint cavity could therefore be related to the amount of neutrophils and thus to the extent of the inflammatory damage.
When the respiratory burst occurs, MPO is most abundantly expressed in neutrophil granulocytes, which then create hypohalous acids to carry out their antimicrobial function through oxidative damage.
What is MPO?Regarding environmental causes, the first one is undoubtedly the existence of an infection and inflammation, which elevate MPO activity and production.
Second, changes to the MPO gene result in its congenital deficit, which makes people more susceptible to infections.
Therefore, the amount of neutrophils and, consequently, the severity of the inflammatory response might be connected by the measurement of MPO levels in the joint cavity.
Therefore, When the respiratory burst occurs, MPO is most abundantly expressed in neutrophil granulocytes, which then create hypohalous acids to carry out their antimicrobial function through oxidative damage.

Suggest why energy from the sun flows in one direction while materials are cycle within an ecosystem
Answer:
Energy flow in an ecosystem is unidirectional. It means that energy which is absorbed by the producers from sun and is converted into chemical energy, always flow from a lower trophic level to a higher trophic level as in a food chain when herbivore consumes producers the energy is transferred from producers to consumers and so on. Some of this energy is assimilated some is used by the organism and some is dessipated in the environment but the flow of energy is never reverted, that is obviously a producer can not consume a consumer.

Answer:
Frogs and voles would have less food supply.
Explanation:
There would be more food for the rabbits and slugs, so their populations would increase. However, ( there would be less food for the frogs and voles), so their populations would decrease. This means less food for the foxes and hawks. However, there are likely to be more rabbits and thrushes for them to eat, so their populations might stay the same.

1. When species come into contact with closely related species, they interbreed and become one species again
2. Medium ground finches with relatively large beaks tend to have offspring with relatively large beaks

4. Speciation, or the evolution of new species, in Galapagos finches results because natural selection favors different beak types on different islands.
False When species come into contact with closely related species, they interbreed and become one species again.
What process lead to the speciation of the Galapagos finches on the different islands?
All of them grew from one progenitor species, which inhabitated the islands only a few million years ago.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
The amino acids which are encoded by the following codons are UUC- Phenylalanine, UCU- Serine, and CUU- leucine amino acid.
What are codons?
A codon is a DNA or RNA sequence which is made up of three nucleotides that forms a unit of the genomic information that encodes for a particular amino acid or signaling the termination of protein synthesis i.e., stop signals in a cell. There are about 64 different codons of which 61 specify amino acids and 3 are used as stop codons that terminate translation process. The 61 codons codes for 20 amino acids in the human beings.
The codons given in this case encodes for different amino acids which are UUC encodes for phenylalanine, UCU encodes for serine amino acid, and CUU encodes for leucine amino acid.
