Describe why the discovery of deep sea thermal vents helps support the abiogenesis theory.

Answers

Answer 1
The discovery of hydrothermal vents changed all that. Vast communities of animals grew big and fast in the depths! Instead of using light to create organic material to live and grow (photosynthesis), microorganisms at the bottom of the food chain at vents used chemicals such as hydrogen sulfide (chemosynthesis).

Answers

Answer:

A-C

Explanation:

Hello There!

Remember these are the complementary base pairs

Adenine and Thymine (so the 2nd and 4th one are correct base pairs)

Cytosine and Guanine ( so the 3rd one is a correct base pair)

Hence, A-C would be the incorrect base pair because like stated previously Adenine pairs with thymine not cytosine

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?

Answers

Answer:

186

Explanation:

The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130  bp + (14 bp x 4) = 130 + 56 = 186.

15. Cells found in plants and animals have similarities but can differ in function. Consider the following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms?

A. The corn cells' have a small vacuole size because it does not need long term water and
electrolyte storage.

B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.

C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.

D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.

Answers

The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.

Explanation to the difference in the cellular vacuole size:

When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.

hence, the correct option is d.

And, the rest of the options are wrong.

Which of the following effects is least likely to be as a result of deforestation?

A: A greater risk of flooding.

B: An increase in biodiversity.

C: An increase in soil erosion.

D: An increase in the level of carbon dioxide in the atmosphere.

Answers

It would be B, because without the forest there would be no animals which means there wouldn’t be anywhere for an increase in biodiversity

The effect that is least likely to be a result of deforestation is an increase in biodiversity. That is option B.

Deforestation is a practice that encourages the clearing of forests for other purposes such as agricultural croplands, urbanization, or mining activities.

This practice needs to be avoided because:

posses a greater risk of flooding as deforestation erodes the soil.they provide a protective cover for the soil against the action of wind and rain thereby preventing soil erosion.the level of carbon dioxide in the atmosphere decreases as it is cleared by trees during photosynthesis.

But deforestation leads to a decrease in biodiversity instead of an increase.

Deforestation can lead to biodiversity loss. This occurs when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct.
