Answer 1

Answer:

Polar bears have thick fur coats that help keep them keep warm in cold conditions. They have a dense layer of fur close to the skin and an outer layer of longer fur. The inner layer isulates them against the cold. ... The skin underneath their fur is black and absorbs the heat from sunlight, helping them stay warm.

What was known before Franklin and Wilkins conducted their studies of DNA? Select three options.

DNA is found in the nucleus of a cell.
The human genetic code is made of 50,000 genes.
Organisms store and transmit genetic information.
DNA has a double-helix structure.
Cells contain protein molecules.

Answers

The correct answer will be-

  1. DNA is found in the nucleus of a cell

   2. Organisms store and transmit genetic information

   3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

        2. Organisms store and transmit genetic information

        3. Cells contain protein molecules.

            are the correct options.

According to the endosymbiotic theory, the cellular process was involved in the evolution of mitochondria and chloroplasts is phagocytosis.

What is endosymbiotic theory?

Endosymbiotic theory is the theory that mitochondria and chloroplasts, which are organelles of eukaryotic cells, originated as independent organisms.

The endosymbiotic theory explains that smaller prokaryotic cells were engulfed by larger prokaryotic cells in a process called phagocytosis.

Therefore, according to the endosymbiotic theory, the cellular process was involved in the evolution of mitochondria and chloroplasts is phagocytosis.

A monohybrid cross is the hybrid of the two individuals with homozygous genotypes or heterozygous genotypes which result in the formation of opposite phenotype for a certain genetic trait. The cross between the two monohybrid traits such as flower color or plant height is called a Monohybrid Cross.

When two plants, one with homozygous yellow leaves (YY) and one with heterozygous yellow leaves (Yy) are crossed, then the offspring will have yellow leaves and none of the offspring will have red colored leaves as this is a recessive trait and it requires to be present in homozygous condition to show its effect.

Passive transport into cells is driven by a concentration gradient; a greater concentration of molecules on one side of the membrane.

Which direction would oxygen move across a cell membrane if there was a greater concentration of oxygen molecules on the inside of the
membrane?

A. It would continue to concentrate inside the cell.
B. The random diffusion of oxygen would balance and have no net effect.
C. Towards the outside of the cell.
D. None of the above.

Answers

Answer:

A. It will continue to concentrate inside the cell.

Explanation:

Due to the higher concentration of oxygen molecules on the inside, oxygen molecules of the outside move to the inside and the more the oxygen molecules move inside the higher the concentration of the oxygen molecules on the inside.

Answer:

A

Explanation:

Towards the outside of the cell.

which statement below correctly describes the process of glycolysis?

A. Glucose is broken down into two pyruvate molecules
B. Oxygen and glucose are broken down
C. Two pyruvate molecules are brown down into glucose
D. Glucose is broken down into ATP

Answers

Answer:

A)glucose is broken down into two pyruvate molecules

The statement below correctly describes the process of glycolysis, glucose is broken down into two pyruvate molecules. The correct option is A.

What is glycolysis?

Glycolysis is the process in which glucose is broken down to produce two molecules of pyruvic acid, which also releases energy. This process can be carried out without the help of oxygen, thus an anaerobic reaction. This process is carried out in the cytoplasm.

For the cell to use as energy, glycolysis results in a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules. Following the conversion of glucose to pyruvate, the Krebs Cycle is connected to the glycolysis pathway, where additional ATP will be produced to meet the energy requirements of the cell.

Therefore, the correct option is A.

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
