Which of the following is the BEST explanation of the role of DNA and RNA in making proteins?

Answers

Answer:

A i think lol

During replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.

What is replication of DNA?

Replication of DNA is defined as the biological process of splitting a single DNA molecule into two identical copies. A double-stranded DNA molecule is copied to create two identical DNA molecules during the DNA replication process. The three primary stages of replication are priming of the template strand, building of the new DNA segment, and opening of the double helix and separation of the DNA strands.

All biological cells contain it, and even though its synthesis takes place in the nucleus, it typically occurs in the cytoplasm of the cell. While DNA provides the instructions for the actions of the cell, RNA is in charge of translating those instructions into proteins that perform diverse cellular tasks.

Thus, during replication, DNA unwinds into two distinct strands, with each strand producing a perfect duplicate of the other. A DNA strand is utilized during translation to create a corresponding strand of mRNA with uracil replacing thymine. Hence option A is correct.

write any three methods of controlling flood landslide and soil erosion​

Answers

You can reduce soil erosion by:
Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Floods can be controlled by redirecting excess water to purpose-built canals or floodways, which in turn divert the water to temporary holding ponds or other bodies of water where there is a lower risk or impact to flooding.

modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.




Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.

All of the following are functions of asexual reproduction except producing gametes.

What do you mean asexual reproduction?

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

Asexual reproduction is a type of reproduction in which only one parent is involved. There are basically 5 types of asexual reproduction. These are binary fission, budding, vegetative reproduction, fragmentation and by spores.

The major disadvantages of asexual reproduction are: Lack of diversity- Since the offsprings are genetically identical to the parent they are more susceptible to the same diseases and nutrient deficiencies as the parent.

Answer: Genetic makeup and environment

Explanation:

Genetic makeup of an organism is dependent upon the genes inherited from the parents. The genes when express are responsible for the development of specific traits in an organism. The environment is also responsible for contributing to the development of traits in an organism. For example, an organism is able to tolerate the cold environmental conditions and can survive in cold habitat as it has inherited traits from the parents but when exposed to hot environmental conditions then it will adapt to the changes in the environment due to development of heat tolerant trait. Also a person has inherited traits of short height from parents but when provided with nutritious food and performs regular physical activities the person had attained tallness due to environmental factors.

Answers

Answer:

yes D is the answer

Explanation:

cuz steam store water carry nutrients and of course provide support to the plant

Stems are the part of the plant and the structural axes that help in support and transport. The stem does not anchor plants to the ground.

What are stems?

Stems are the axis of the plant that bears shoots, leaves, buds, flowers, etc. The stem of the plant conducts water and mineral through the vascular system of the xylem and phloem.

The roots of the plant provide an anchor to the stem. They also store food and water in their structures that are used for further use and make them available at the time of requirement.

The stems are the mechanical structure that provides support to the plant parts and enables them to stand upright.

Therefore, option D. anchor to the ground is not provided by the stem.

Answers

I'm a bit confused about this question. But I will try my best to answer. :)

To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.

I hope this helps! :)

A hapten is a substance containing incomplete portions of a virus that produce an immune response when injected into the body.

What is the Immune response?

The immune response may be defined as the type of reaction that occurs in response to specific antigens or foreign agents. Such types of responses defend the organism against foreign invaders.

A hapten is essentially an incomplete antigenic particle. Such small substances or molecules only elicit an immune response when attached to a carrier known as proteins.  

Carrier molecules typically do not elicit an immune response by themselves.

Therefore, it is well described above.

Due to the variety of sediments that make up sedimentary rocks, these rocks frequently have a layered look. In the second image, an igneous rock is seen. When molten rock, or magma, cools and hardens, igneous rocks are created.
