30. How many DNA codes are used by life on Earth?

Answers

Answer 1
Answer:

The DNA code contains 64 combinations that are named as codons. These codons are coding for the 20 amino acids, which the cell then puts together to form long amino acid chains, known as proteins.

What is DNA?

DNA stands for deoxyribonucleic acid. It may be defined as a molecule that is present inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.

There are 3.2 billion DNA codes that are used by life on Earth. Of the three billion genetic building blocks that make us living things, only a handful are uniquely ours. In fact, despite our differences on the outside, humans are 99.9% genetically similar to one another.

Our genetic manual holds the instructions for the proteins that make up and power our bodies. But less than 2 percent of our DNA actually codes for them. The rest 98.5 percent of DNA sequences is so-called “junk DNA” that scientists long thought useless.

Answer 2
Answer:

Answer:

That's how much information is stored in the DNA inside every human cell: the entire human genome. If you sort through the three billion letters that make up the human genome, you find some surprising things. Only about 1% of the three billion letters directly codes for proteins.

differentiate

Answers

Elongation is a developmental process which is regulated by light and phytohormone. After elongation, plant cells begin to differentiate.  During the period of differentiation cells of the root and the shoot apical meristems and the cambium mature, the cells cell evolve in to a specialized cells and begin to take on their individual functions.

Answer:

C- differentiate

Explanation:

Glucose derivatives can produce a number of different molecules, including sugar acids. Below are three sugar acids. (1) Indicate which carbon has been oxidized in glucose to produce the sugar acid and (2) match the function of the sugar acid by selecting the letter associated with a description. This will require you to investigate functions!a. This sugar acid is used as a substrate in glucuronosylation reactions to modify other insoluble molecules, forming glucuronides that are water soluble and can be more efficiently eliminated from the body as waste. b. Produced in small amounts in mammals, but found in higher amounts in fruits, including apples and grapefruits. This sugar acid has been shown to limit hormone-dependent cancers through inhibition of β-glucuronidase. c. Found in honey, where the pH is kept acidic to inhibit growth of microorganisms. This sugar acid is produced by the enzyme glucose oxidase and serves to enhance flavor.
i. Gluconic Acid: oxidation at __________, function description letter ____ ii. Glucuronic Acid: oxidation at _________, function description letter ____ iii. Glucaric Acid: oxidation at _________, function description letter ____

Answers

Gluconic Acid: oxidation at carbonyl (1st) carbon, function description letter c.
Glucuronic Acid: oxidation at last (6th) carbon, function description letter a.
Glucaric Acid: oxidation at both carbonyl and last carbon, function description letter b.

According to the site of oxidation, sugars are classified into different groups. The name of the sugar suggest which group it belongs:
1. Aldonic acids - carbon is oxidized at carbonyl carbon -  e.g. gluconic acid.
2. Uronic acids - carbon is oxidized at last carbon - e.g. glucuronic acid. 
3. Aldaric acids - carbon is oxidized at both carbonyl and last carbon - e.g. glucaric acid.

A scientist claims that volcanic eruptions caused dinosaurs to become extinct at this location. Decide whether you agree or disagree with the scientist's claim and then explain your decision.

Answers

Answer:

Dinosaurs are the extinct organisms that belong to the class reptilia. Dinosaurs are the most advanced and bulkier reptiles at the history time and they were overspecialized in their environment.

The dinosaurs extinct rapidly due to the change in the external conditions and the volcanic eruptions that occur at the dinosaurs time. The recent searcher claims that asteroid impact and massive volcanic eruption leads to the dinosaur extinction. The fossil evidence and the presence of the specific basalt and other chemicals are found in the volcanoes and in the asteroid.  

Give Reason:-1)Vegetables release water after salt is added to them

2) Nucleus is absent in red blood cells

3) The skin of your fingers shrinks when you wash clothes for a long time

4) Inner membrane of mitochondria is folded

5) Vegetable vendors regularly sprinkle water on the vegetables in their baskets.

6)Endocytosis occurs only in animals

Answers

reason :
there are two reasons for this due to attraction of positive salt ions or negative water ions or it happens because the vegetable has more concentration of water init while in surrounding has low concentration of water so they try to lose water to attain equilibrium with respect to their surrounding...this is called osmosis...
2 reason:
due to absence of nucleus in red blood cells it is biconcave in shape,,,,
it is absent so that RBCs have more space to carry out oxygen 
also this absence make the cell able to bend whenever it is passed through bloodstream:)
3 reason:
our skin in water shrinks because the outermost layer of our skin swells by absorbing water but at the same time underneath layer gets tightly attach to it ,,,to compensate the surface area so it seems shrink...
4 reason:
to increase the surface area as a result of which large and faster production of ATPs takes place ...
5 reason:
so that vegetables do not get dry ,,, because they dry they do not look fresh...
6 reason:
endocytosis is a process in which cell membrane engulfs material... but in plant cell cell membrane is not present they have cell walls :)


In reef-building corals, a symbiotic relationship exists between corals and a type of algae that live in their tissues. The corals gain energy and oxygen from this association, while the algae obtain carbon dioxide, nitrogen, and a stable habitat. This type of relationship is best categorized as

Answers

Answer:

Mutualism

Explanation:

In mutualism, both of the organisms benefit from the relationship.

This situation is an example of mutualism, as both the algae and corals benefit.

The algae benefit by receiving carbon dioxide, nitrogen, and a stable habitat. Likewise, the corals also benefit by gaining energy and oxygen.

So, this relationship is best categorized as mutualism.
