A student did an experiment with two identical fish tanks, Tank 1 and Tank 2. About 20 ml water purifier was added to Tank 1 and 10 ml
water punfier was added to tank 2. Tank 1 was heated to 88° F and Tank 2 was left at room temperature. The water purity of each tank was
tested every day in particles per liter. The purity was recorded over a period of 5 weeks in the table shown below.

pleasee helppp !!​

Answers

Answer 1

Answer:

a . Fish need 10 ml of water purifier to survive.

Explanation:

Fish need 10 ml of water purifier to survive because the data of 10 ml and 20 ml purifier is the same so it is recommended to use 10 ml purifier. First the data was same but by recording next week data, it shows slightly increase in the value of tank 2 while in the last week, both has the same value so we can concluded that by using 10 ml purifier is enough for the fish to survive.

Answer 2

Answer:

Its B/More purifier is needed to keep heated water clean.

Cloning to produce embryonic stem cells is called A) regenerative cloning. B) transplantational cloning. C) reproductive cloning. D) therapeutic cloning. E) dedifferentiation.

Answers

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 cloningGene cloningTherapeutic cloning

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.

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

The tissue below the epidermis of a leaf stalk is Collenchyma.
Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.

In which of the following ways is DNA replication different from DNA transcription?

Answers

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.

You continue this approach by designing two separate experiments. In the first experiment, you use glucose where "Coccupies position 1. In the second experiments, 14C occupies position 2 and 6 in the glucose molecules. For each experiment, you use 0.2 moles of radiolabeled glucose and you assume that all the pyruvate formed is converted to acetyl-CoA. What following statements are correct? (select 3)
a) When glucose is labeled on carbon #1, 0.2 mole of acetyl-CoA is radiolabeled
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
d) When glucose is labeled on carbons #2 and 6, 0.1 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

Answers

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.

c. Anti-tumor T lymphocytes that have high expression of CTLA-4.
d. A tumor with high expression of PD-L1.

Answers

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.

What is PAMP-DAMP complexes?

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.

Have you ever noticed that aside from zoos, you don't see kangaroos, wombats, and koala bears outside of Australia? This is because there is a trench that is a "biogeographical transition zone between Asian and Australian flora and fauna". What is the name of that trench?

Answers

Answer:

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.
