HURRY PLEASE!! Explain how the DNA molecule is stabilized but also able to be changed.

Biology

The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.

Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)

Hope this was able to help you! I went through my answer and bolded the more important parts, and parts more useful for answering the question.

1 ml of water should weigh 1 gram. You measured the weight of 1 ml of water using
8090 [49]

Answer:

20%

Explanation:

Given that:

Actual weight of 1 mL of water =. 1g

Average weight using :

TOOL A = 1.2

TOOL B = 1.5

Percentage Error of TOOL A:

(|approximate measurement - actual measurement| / actual measurement) * 100%

(|1.2 - 1| / 1) * 100%

(0.2 / 1) * 100%

0.2 * 100%

= 20%

Can a mesophile be forced to grow at obligate thermophilic temperatures? Can a mesophile be forced to grow at obligate thermophi
ad-work [718]

Answer: No, the enzymes will not work at such high temperatures

Explanation: Mesophile are organism that grows or thrive well when the temperature is moderate. They do not grow or do well when the temprature is too hot or cold. They can be found in cheese and yoghurt and are useful during fermentation process.

Human pathogen are mesophils they do well at normal body temperature.

Thermophiles are organims that grows at high temperature. Mesophile cannot be forces to grow at thermophile temperature because the enzyme will be inactive at high temperature they can only be active at normal tempertaure

Drag each label to the correct location on the image.Identify the missing parts of the carbon cycle.photosynthesisburning oil an
algol13

To answer this question we need to remember quickly how the carbon cycle works, a part of the free carbon dioxide in the atmosphere is captured by plants through photosynthesis, other dissolves into water bodies, and some more remains in the atmosphere. This fixated carbon by plants passes to animals where can integrate into the soil or be released again into the atmosphere. The carbon that remains in the soul can form fossil fuels that are used by humans in the industry and released once more to the atmosphere. Therefore taking this into account we can say that that order is as follows:

Photosynthesis: Plants

Burning oil and coal: Factories

Respiration: Animals

Decomposers: Fossil fuels

Suppose the interior of the thylakoids of isolated chloroplasts were made acidic and then transferred in the dark to a pH-8 solu
Olenka [21]

Answer:

The correct answer will be option-A

Explanation:

Thylakoid is the structure in the chloroplast where the light-dependent reaction takes place which forms the ATP and NADPH.

The production of ATP takes place due to the movement of Hydrogen ions across the membrane from the interior or lumen to the stroma of the chloroplast.

If the thylakoid were made acidic that is hydrogen ion concentration increases inside the lumen and then kept in a basic solution where the hydrogen concentration is low then it will lead to generation of a proton gradient.

The generation of the proton gradient will cause the movement of the protons from the lumen to the outside through ATP synthase which will produce ATP.

Thus,  option-A is the correct answer.
