Why is transcription essential for making proteins

Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

Which might increase the human carrying capacity during the twenty-first century?

vichka [17]

Answer:

new technological advances

Explanation:

The carrying capacity indicates the maximum population of a particular species that a given area of habitat can support over a given period without destroying or depleting the resource base.

Carrying capacity can be affected by factors such as technological advances, trade and use of fossil fuels for energy . Changes in technology modify the carrying capacity of a population. An example is the use of irrigation and fertilisation in agriculture or shortening rotations between crops, which increases the number of people who can be fed from the resources of a given population due to increased yield.

A biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. What type of data will

iragen [17]

Answer:

$\boxed {\boxed {\sf They \ will \ gather \ quantitative \ data \ using \ a \ thermometer \ and \ a \ balance}}$

Explanation:

First, let's identify the tools needed.

Since the biology class is studying the temperature, they will likely need a thermometer. Also, they are gathering information about the growth of the plants. This could use a balance of a meterstick.

Next, recall the difference between quantitative and qualitative data.

Quantitative: Measurable and numerical results found using scientific instruments/devices
Qualitative: Data found using the senses, such as descriptions and diagrams.

Since the class is measuring temperature and growth using tools, it must be quantitative data.

We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
