I would THINK that the historical theme would be "The cause of air pollution and the effects of it on sugarcane farms."

Hey there budd!

Your question is stated above: <span>Which option describes what the U.S. Green Building Council has created?

Based from my information, I know for a fact the the answer would NOT be option D. The government would not </span>to simplify the certification process for sustainable building and construction because they want (high) quality people working for them, not people who have low certificates to work for the government.

I (seriously) believe that the correct answer to this question would actually be the first option. (A) Government control over all engineering design materials. So, this would show you that the U.S. Green Building Council has created a government to watch over and control everything that is being designed.

I hope this helps you!

5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?

dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.

In the game peek-a-boo, the mother initially covers the baby. then she removes the cover and registers "surprise" at the infant'

alisha [4.7K]

Answer;

-Scaffolding

Explanation;

Scaffolding as a metaphor in teaching and learning describes the adaptive and temporary support provided by a more competent person (e.g., teacher or adult) to a less competent person (e.g., student or child). For example; mother–child interaction during the game of peekaboo.

Scaffolding is one of the several aspects of effective instruction that can be applied in the context of language learning. Although teachers might be enthusiastic about the idea of scaffolding, it must be borne in mind that scaffolding is not simply synonymous with teacher support.

Is it better to learn about animals through a book, or actually going to see them in real life?

Norma-Jean [14]

I think in real life because you get to see how they act and i have been on three trips i know that this is not related but I've been to Egypt and Italy and china and i am in 7th grade so ya. I think seeing animals and things in real life is the best thing to do overall.

imagine a cell-surface receptor protein is being newly synthesized. How can it get into the membrane that it will ultimately be

motikmotik

Answer:

the steps for a new receptor synthesis:

Explanation:

Do not forget the steps vary from an eukarityc cell to prokarityc one.

IN AN EUKARYOTIC CELL:

1- Transcription: in the nucleus, mRNA is synthesized from the DNA sequence that codifies the protein. Exons are spliced if needed by spliceosomes.

2- From nucleus into cytoplasm: mRNA goes through nuclear membrane into the cytoplasm were ribosomes, substrates for protein synthesis and other organelles are.

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- (The mRNA has a signal that is recognized by the rough endoplasmic reticulum) The peptide goes into this reticulum (RER) and then into Golgi apparatus. (more chemical modifications are made if needed). By this moment the protein has an inserted portion in a lipid membrane.

6- The protein is transported in a vessel that finally fusions with cytoplasmic membrane and the receptor is in destiny. Hydrophobic aminoacid sequences are inserted in membrane.

IN A PROKARYTIC CELL:

1- Transcription (no splicing is needed, there are not exons)

2- There are not nucleus and cytoplasm divided (no transport)

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- The mRNA has a signal that is guides the growing protein to cellular membrane. Hydrophobic aminoacid sequences are inserted in membrane.
