4. Explain why transcription must occur in the nucleus.



5. Why does a cell need to carry out transcription before translation?

Answers

Answer:

4. Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.

5. Transcription needs to occur before translation because the product of transcription, messenger RNA (mRNA), is the starting material for translation.

Which of The following are challenges to implementing sustainable farming practices? Select two correct answers.

a. increased need for fertilizer
b. lack of pollinating insects
c. higher initial costs
d. increased erosion
e. increase labor costs

Answers

Answer:

I think its A and E

Explanation:

^^^^^^

The challenges to implementing sustainable farming practices: higher initial costs;  increase labor costs.

What is  sustainable agriculture?

It is an integrated system which includes both plant and animal farming practices, which hence has a minimum effect on the environment. It involves using substances of natural origin and hence meets the needs without causing an adverse impact on the environment.

What are its advantages?It prevents pollution since the waste remains in the farm's ecosystem.There is a reduction in the production of waste, and the waste of one is used in the other.It saves energy as there is a lower requirement for non-renewable resources.It doesn't use agrochemicals.It involves methods that reduce soil erosion, like managing irrigation, covering the soil with tillage.What are its disadvantages?It takes more effort since the use of machines is minimal.Limited use of land and hence, mass production is not possible.What are the challenges?New farmers have to struggle with high labor demand since it involves less use of machines and hence more workers are required.Before harvesting their first crop, young farmers require a huge sum of up-front capital, which is even more for biologically diverse farms.

Hence the correct options are (c) and (e) higher initial costs;  increase labor costs.

Answers

Answer:

The answer is option A "Is True"

Explanation:

The Monarch is notable for its capacity to travel significant stretches, and the migrations in North America are one of the best common marvels on the planet. This butterfly is additionally periodically recorded from the English Isles, making it our biggest and most extraordinary traveler butterfly.

Each fall, a great many ruler butterflies move 3,000 miles from their favorable places in northeastern North America to spend the colder time of year in the timber lands of southwestern Mexico. Every movement is by new generation, so they can't gain from others. All things being equal, they depend on their qualities. Their antennae have a genetic clock that reveals to them when to move and to explore they measure the sun's situation not too far off with their eyes.

Describe the steps of protein synthesis in a eukaryote.

Answers

The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.

The second step is  translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.

Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.

What is protein synthesis in a eukaryote?

The mRNA exits the nucleus and attaches to a ribosome in the second step of translation. Protein synthesis takes place in ribosomes. An amino acid is created for every three nitrogenous bases in the mRNA.

Transfer RNA transports amino acids to the location where proteins are synthesized. We are left with a polypeptide after this procedure.

The primary level of regulation of eukaryotic gene expression is transcription.

Therefore, the process of transcription involves an enzyme-producing messenger RNA (RNA-polymerase).

Scientists have discovered a new molecule found in the blood of wallabies. The molecule contains only carbon, hydrogen, and oxygen. After further examination, scientists discovered that the C, H, and O are in a 1:2:1 ratio. This molecule is most likely a ________.?

Answers

Answer:

carbohydrate

Explanation:

The molecule discovered by scientists in the illustration is most likely to be a carbohydrate.

Among all the biomolecules, only carbohydrates have the molecular formula of ([tex]CH_2O[/tex])[tex]_n[/tex]. On the other hand, carbohydrates generally contain carbon (C), hydrogen (H), and oxygen (O) in the ratio 1:2:1.

Since the molecule discovered by the scientists has C, H, and O in the ratio 1:2:1, then, it is, therefore, best thought of as a carbohydrate.
