A city is located in an area that has experienced 7.5-magnitude earthquakes in the past. The city is considering building a new skyscraper.

Use the earthquake magnitude scale to predict the amount and type of damage residents should expect from future earthquakes of similar magnitude. Then suggest a way to minimize the effects of future earthquakes on the skyscraper.

Answers

Answer:

The residents should expect collapsing parts of the building, or even the building itself would collapse if the building cannot hold/not sturdy enough for earthquakes ranging around 7.0m to 7.9m. If the building is built by hills or rocky land, expect landslides to be happening. A way effects of future earthquakes can be minimized is that the building should be constructed with sturdy material (such as steel) so that it can withstand most of the force of a 7.0-7.9m earthquake.

Explanation:

The “code” for physical traits is found in a molecule called DNA. Segments of this molecule that code for specific proteins are called genes. In order to conserve space and protect the molecule, DNA wraps around proteins to form chromatin. When a cell is about to divide, DNA wraps up even tighter into  chromosomes.  Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.

The "code" for physical traits is contained in a molecule is called DNA (genetic code).

Segments of this molecule that code for specific are called genes.

In order to conserve space and protect the molecule, DNA wraps around proteins to form nucleosomes.

What a cell is about to divide, DNA wraps up even tighter into chromosomes.

Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.

organization of a chloroplast. Then below, answer the questions to describe how the
different parts are related to each other.
Chloroplast

Answers

Answer:

Chloroplast -----membranes----------internal

                                              ---------external

                   ----- Tylacoids-------------Grana

                   ----- Stroma

You will find the complete concept map in the attached files

Explanation:

The chloroplasts are limited by two membranes, the internal and the external membranes. Both of them are separated by the intermembrane space.

In the interior of the organelle, thylakoids are composing the third system of membranes. In the interior of thylakoids, there is an additional compartment named thylakoid space. This membrane system forms piles, known as grana. Different grana structures connect to each other by a longer thylakoid membrane. The photosynthetic pigments are located in the thylakoids, where it occurs the light-dependent reactions.

Surrounding the thylakoids there is a dense liquid called the stroma. Here takes a place the Calvin cycle.

To fill in the diagram you will need to show the composition of the chloroplast. Therefore, you should show the internal and external membranes, the thylakoids, the grana, and the stroma.

We can arrive at this answer as follows:

Chloroplasts are organelles present in plant cells, they are very important in the photosynthetic process.Chloroplasts have two membranes, an internal and an external one, which limits the entry and exit of substances.Inside the chloroplasts are the thylakoids, which are formed by structures called grana, which form numerous piles, which resemble towers.The unoccupied space within the chloroplast is filled with a fluid called the stroma.

In the figure below you can see how this diagram can be filled.

What is the purpose of protein synthesis?

Answers

Answer:

Protein synthesis is the process all cells use to make proteins, which are responsible for all cell structure and function. There are two main steps to protein synthesis. In transcription, DNA is copied to mRNA, which is used as a template for the instructions to make protein.

Explanation:

Proteins are one of the most important biomolecules essential for the survival of organisms owing to the myriad of functions that they play in the physiological system.

Proteins that are ingested are easily degraded to amino acids or peptides by the action of HCl in stomach and the digestive enzymes present in the gastrointestinal tract. Thus, proteins have to be synthesized in the body to meet the body's needs for various functions.

Some of the functions of proteins include:

1.  Enzymes are majorly proteinaceous in nature and are required for crucial functions, including cell division and DNA synthesis.

2. Motor proteins help in movement and also provide cytoskeletal structure to the body.

3. They are required for the functioning of the immune system.

4. Proteins are required for cell signaling pathways.
