Choose only one correct option. Explanation needed.

Answer:

b) When glucose is labeled on carbon #1, 0.1 mole of acetyl-CoA is radiolabeled

c) When glucose is labeled on carbons #2 and #6, 0.2 mole of acetyl-CoA is radiolabeled

e) When glucose is labeled on carbons #2 and 6, the carbonyl groups of half of the acetyl-CoA molecules are radiolabeled

f) When glucose is labeled on carbons #2 and 6, the methyl groups of half of the acetyl-CoA molecules are radiolabeled

Explanation:

When glucose undergoes glycolysis, it is converted into two molecules of pyruvate with carbon 1 to 3 forming the first molecule of pyruvate and carbon 4 to 6 the second molecule of pyruvate. The C-1 and C-6 of the glucose molecule becomes the methyl groups of each of the two molecules of pyruvate. The C-2 and C-5  of the glucose molecule forms the carbonyl carbon of each of the two pyruvate molecules. Each of the two pyruvate molecules undergoes further oxidation to yield acetyl-CoA with the carbonyl and methyl groups of pyruvate retained in the acetyl-CoA molecules.

Thus when 0.2 moles of glucose are labelled at C-1 and then C-2 and C-6 in each of the two experiments the following results are obtained:

When glucose is labeled on carbon-1, 0.1 mole of acetyl-CoA is radiolabeled  since half of the two pyruvate molecules are obtained from C-1

When glucose is labeled on carbon-2 and carbon-6, 0.2 mole of acetyl-CoA is radiolabeled since the C-2 and C-6 of the glucose molecules forms a part of one of each of the two pyruvate molecules.

When glucose is labeled on carbons #2 and 6, the carbonyl groups of half of the acetyl-CoA molecules are radiolabeled since one of the two carbonyl groups of the two pyruvate molecules is  formed from C-2 of glucose.

When glucose is labeled on carbon-2 and carbon-6, the methyl groups of half of the acetyl-CoA molecules are radiolabeled since one of the two methyl groups of the two pyruvate molecules is  formed from C-6 of glucose.

Collenchyma is the tissue found below the epidermis of a leaf stalk. These are simple permanent tissue, perform photosynthesis when chloroplast is present.

Answer:

Mitotic cell division creates identical copies by replicating a cell's DNA once and then dividing once.

Answer:

The answer is A.

Explanation:

The best fossil evidence that suggests Neandertals' ability to produce a language like modern humans comes from the hyoid bone.

This bone is located in the neck between the chin and the thyroid, which is also named "tongue bone" or "language bone".

So the correct answer is A.

Did you ever figure out the answer to this question?

The study of PAMP-DAMP complexes is vital to the advancement of knowledge regarding inflammatory disorders in general and cancer in particular. Therefore, option (B) is correct.

Increasing evidence links inflammation to cancer, and at the root of inflammation are PAMPs and DAMPs (DAMPs). Microorganisms contain PAMPs, which are detected by pattern recognition receptors on monocytes and DCs (PRRs). PRR activation produces pro-inflammatory cytokines.

A robust immune response requires endogenous chemicals that pose 'risk' to self-tissues and are created by injured or stressed cells; these are DAMPs, which also trigger inflammation. PAMPs and DAMPs each have about 100 receptors. PAMPs and DAMPs interact; a PRR can bind to both. In this system, PAMPs and DAMPs affect each other's activation threshold. Thus, PAMP-DAMP relationships describe inflammation in a predictable 'inflammatory code'

PAMP-DAMP complexes are key to understanding inflammatory disorders and cancer.

Answer:

Thymine is used in replication while uracil is used in transcription.

Explanation:

New cells can only be created after transcription has taken place. Replication results in mRNA strands while transcription creates new DNA. Transcription happens outside the nucleus and replication happens inside the nucleus. Thymine is used in replication while uracil is used in transcription.

DNA replication is a process whereby DNA makes a copy of itself while DNA transcription is a process whereby a messenger RNA is synthesized from a DNA strand.

Both processes involve the building-up of nucleotides or purine.pyrimidine bases. Replication involves building up of cytosine, guanines, adenine, and thymine bases while in transcription, the thymine base is replaced by uracil base.

Hence, the correct answer is that Thymine is used in replication while uracil is used in transcription.

Answer:

D

Explanation:

The correct option would be therapeutic cloning.

First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.

Artificial clonings are of different types, namely:

Reproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.

Nutrient collapse in the agriculture research it the mos important foods been getting nutrition less, they generally vegetables, fruits minerals and vitamin, protein content has to past.

The researching choosing crops for higher yields and nutrition and wheat to less nutrient,fruits and vegetables that form protein to calcium, iron and vitamin are varieties choosing to grow.

Wallace Line

Explanation:

Wallace Line is a boundary line which is a transitional zone between Asia and Australia. This boundary drawn by the British naturalist Alfred Russel Wallace in 1859. This boundary restricts the transferring organisms such as flora and fauna from Australia to Asia. So that's why kangaroos, wombats, and koala bears are only present in Australia not in the continent of Asia.
