Answers

Step 1: dna interacts with rna polymerase
Step 2: mRNA molecule is produced
Step 3: mRNA interacts with a ribosome
Step 4 protein molecule is produced

The correct order is DNA interacts with RNA polymerase (1), the mRNA molecule is generated (2), mRNA interacts with a ribosome, and protein is produced (4).

What is transcription?

Transcription (gene transcription) is the process by which a fragment of DNA is employed to generate an mRNA.

This messenger RNA (mRNA) then travels to the ribosomes in the cytoplasm to generate a protein.

The process of translation refers to the protein synthesis by an mRNA template.

In conclusion, the correct order is DNA interacts with RNA polymerase (1), the mRNA molecule is generated (2), mRNA interacts with a ribosome, and protein is produced (4).

If a SARS-CoV2 virus were to mutate and become and become better at attaching to respiratory cells, how would natural selection lead to this mutant virus becoming the dominant virus type? Use the four steps of natural selection in your response: overpopulation, genetic variation, competition, differential reproductio.

Answers

Answer:

Mutations leading to the better attachement of virus to the host cell would allow the virus to spread the infection and leave more progeny. The reproductive fitness of mutant viruses would allow the mutation to spread.

Explanation:

1. The organisms with same resource requirement compete with each other. Viruses are not living things but once inside the host cell, they behave like living things. Rapid multiplication of virus overpopulate the host cells.

2. Genetic variations are added to the viral progeny by random errors during replication of the viral genome. These random variations may  impart beneficial trait, harmful feature or remain neutral. If a random mutation in the SARS-CoV2 virus allows it to adhere better to the cells of the respiratory system, the virus would be better able to infect these cells to spread the infection. Once inside the host cells, the mutant virus would leave more progeny. On the other hand, the wild type virus that lack this mutation would  have lesser chances of entering the host cells and may or may not replicate.

3. The progeny of the mutant virus would compete better with the non mutant ones due to the presence of same mutation.

4. Differential reproduction and more progeny of the mutant virus would spread the mutation among the virus.

What are cellular organisms?

Cellular organisms are living beings that consist of one or more cells. Cells are the basic unit of life and the building blocks of all living organisms. Cellular organisms include all living things from bacteria to complex multicellular organisms such as plants and animals.

Cells have a variety of structures and functions depending on the type of organism they belong to. In unicellular organisms, such as bacteria, a single cell performs all the functions required for life. In multicellular organisms, cells are specialized to perform different functions, such as carrying oxygen in red blood cells or detecting light in the retina of the eye.

Cellular organisms have the ability to reproduce, grow, and respond to their environment. The study of cellular organisms is fundamental to the fields of biology, medicine, and biotechnology.

Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experamint did he perform to test this idea

Answers

Answer: He performed dihybrid crosses

Explanation:

Dihybrid cross is simply refered to as a cross that is done for two genes that are different with regards to their traits. For example, if we cross two maize plants which have different shapes and color let's say that one is white and round while the other maize's colour is yellow and its shape is wrinkly.

Since Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another, the experiment performed will be dihybrid crosses.

90% H2O 10% Solute The solution is: hypertonic / hypotonic / isotonic Water will: not move / move into the cell / move out of the cell

Answers

Answer:

Hypotonic / moves into the cell.

Explanation:

Hope you have a nice evening.

The solution is hypotonic. Water will move into the cell.

What is hypotonic solution?

A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell. In this case, the solution is composed of 90% water and 10% solute, which is a lower concentration of solutes than inside the cell.

As a result, water will move into the cell in order to balance the concentration of solutes and maintain homeostasis. This can cause the cell to swell and may even lead to lysis if the cell is unable to handle the increased volume.
