Answer:

We could use up all of them right away and not have the resources for humans and animals to survive.

Explanation:

Right now, we are using our natural resources at a consistent rate. We sometimes use to many of them in one day. If we continue using up our natural resources at the rate we are right now. We may not have the necessary resources to survive in about 10-20 years.

Hope this helps!

Answer:

C. containing

egg albumen
protease
dilute hydrochloric acid

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

Enzymes speed up reaction rates by providing alternative pathways. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.

Vladimir79 [104]

The given question is incomplete, the complete question is:

Oh, no... you dropped your study flashcards, and now they're out of order! Put them back into the correct order for a eukaryotic cell.

a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."

b. "Unwind the DNA molecule near the promoter."

c. "Exit the nucleus to the cytoplasm."

d. "Transcribe the complementary RNA strand."

[Tip: you might want to work out the correct order on a piece of scratch paper before selecting from the options below.]

c - d - b - a

b - d - c - a

c - b - d - a

d - b - c - a

b - d - a - c

Answer:

The correct order would be b, d, c, a.

Explanation:

First unwinding of the molecule of DNA takes place close to the promoter. After that transcription of the complementary RNA strand takes place, then mRNA moves out of the nucleus into the cytoplasm. Ultimately, the combination of ribosome and tRNA carrying a methionine takes place with the mRNA.

The order is based upon the central dogma of the cell. Based on the central dogma concept, the transcription of the mRNA takes place in the first place, which then gets transported out of the nucleus into the cytoplasm in the eukaryotic cell. The unwinding of DNA takes place close to the sequence of the promoter for the process of transcription.

In the promoter region, various transcription factors are present and binding of RNA polymerase takes place with the template strand. The generated mRNA then get transported out of the nucleus into the cytoplasm. Post transcription, translation of mRNA takes place with the assistance of tRNA and ribosome. In the mRNA, the start codon generally codes for methionine because of which the tRNA that carries methionine identifies the start codon, and the process of translation gets initiated.
