Which of the following events happens during
Translation?
new tRNA molecules are made
DNA splits in half and moves into the cytoplasm
different types of RNA work to create an amino acid chain
a new mRNA molecule is made

Answers

Answer:

mRNA binds directly to amino acids during translation

Lil more info

mRNA is transcribed from DNA in the cytoplasm. mRNA moves from the nucleus to the cytoplasm following RNA processing. mRNA moves from the nucleus to the cytoplasm following RNA processing.

During the translation process in the cell, various types of RNA collaborate to form an amino acid chain, which is present in the third option as the amino acids make the chain that is called the polypeptide chain.

What roles do different RNAs play in translation?

In the translation process, different RNAs are involved: the mRNA, which contains the codon sequence, which is the base; the tRNA, which contains the amino acid; and the rRNA, which is the ribosomal RNA. All of these RNAs combine to form the amino acid chain. This is the active translation process because ATP is required for the release of amino acids from tRNA and the translation of mRNA.

Hence, during  the translation process in the cell, various types of RNA collaborate to form an amino acid chain, which is present in the third option as the amino acids make the chain that is called the polypeptide chain.

Question:
Explain what monsoons are, where they are often found, and what impact they have on the environment.
You must use complete sentences when answering this question.

Answers

Answer:

Explanation:

a seasonal prevailing wind in the region of South and Southeast Asia, blowing from the southwest between May and September and bringing rain (the wet monsoon ), or from the northeast between October and April (the dry monsoon ).

Answer:

a monsoon is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation, the summer monsoon is associated with heavy rainfall. it usually happens between April and September. as winter ends, warm, moist air from the southwest Indian Ocean blows toward countries like India, Sri Lanka, Bangladesh, and Myanmar. the summer monsoon brings a humid climate and torrential rainfall to these areas. India, Costa Rica, and Nicaragua are main locations. while too little rainfall during the summer monsoon can cause dire conditions for farmers on land, too much rainfall and overly strong winds can make coastal waters unsafe, preventing fishermen throughout South Asia from heading to sea to catch the fish they depend on for income. in dry climates, monsoons are an important replenishment for life as water is brought back into drought-stricken zones of the world. But the monsoon cycle is a delicate balance. If rains start late, are too heavy, or not heavy enough, they can spell disaster for people's livestock, crops, and lives.

Internet technology is used to provide

and last one:

When the body starts to cool, this causes phase change materials in clothing to release
___________ back to the body.

Answers

First is information

The first one is e-commerce.

The second one is heat.

Internet technology is used to provide  e-commerce sites that allow fashion designers to sell their products.

When the body starts to cool, this causes phase change materials in clothing to release  heat back to the body.

The assignment on Edg states:

-"Some fashion designers create sketches by hand while many use computer-aided design programs (CADs). Another benefit of STEM, CAD programs allow designers to view their designs on virtual models. They can also view different shapes, designs, and colors all from their computers. In general, it takes about six months for the complete design process, from initial design to final product. Besides selling their designs in stores, many fashion designers use e-commerce and the Internet to sell their products."

-"Outlast Adaptive Comfort products create temperature-regulating textiles. Outlast technology uses phase change materials (PCM) that collect and store excess heat from the body. When the body cools, the material then releases heat back to the body for optimal thermal comfort. This material can be incorporated into fibers and fabrics. With a material such as that, heavy coats and winter-wear clothing may not be needed!"

How fast is this wavetraveling? Source 1: Excerpt from Senate Report 693, 46th Congress, 2nd Session (1880). Freed by the Emancipation Proclamation in 1865, former slave Henry Adams testified before the U.S. Senate fifteen years later about the early days of his freedom, describing the process of sharecropping.The white men read a paper to all of us colored people telling us that we were free and could go where we pleased and work for who we pleased. The man I belonged to told me it was best to stay with him. He said, The bad white men was mad with the Negroes because they were free and they would kill you all for fun. He said, stay where we are living and we could get protection from our old masters. I told him I thought that every man, when he was free, could have his rights and protect themselves. He said, The colored people could never protect themselves among the white people. So you had all better stay with the white people who raised you and make contracts with them to work by the year for one-fifth of all you make. And next year you can get one-third, and the next you maybe work for one-half you make. We have contracts for you all to sign, to work for one-twentieth you make from now until the crop is ended, and then next year you all can make another crop and get more of it.I told him I would not sign anything. I said, I might sign to be killed. I believe the white people is trying to fool us. But he said again, Sign this contract so I can take it to the Yankees and have it recorded. All our colored people signed it but myself and a boy named Samuel Jefferson. All who lived on the place was about sixty, young and old. On the day after all had signed the contracts, we went to cutting oats. I asked the boss, Could we get any of the oats? He said, No; the oats were made before you were free. After that he told us to get timber to build a sugar-mill to make molasses. We did so. On the 13th day of July 1865 we started to pull fodder. I asked the boss would he make a bargain to give us half of all the fodder we would pull. He said we may pull two or three stacks and then we could have all the other. I told him we wanted half, so if we only pulled two or three stacks we would get half of that. He said, All right. We got that and part of the corn we made. We made five bales of cotton but we did not get a pound of that. We made two or three hundred gallons of molasses and only got what we could eat. We made about eight-hundred bushel of potatoes; we got a few to eat. We split rails three or four weeks and got not a cent for that.1.
