A cross country runner runs 8 km in 2 minutes. What is his speed?

Answers

Answer 1

The speed of the cross country runner is equal to 4 km/min.

Given the following data:

Distance = 8 km.Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Speed = \frac{8}{2}[/tex]

Speed = 4 km/min.

2.) What is the start codon? What are the 3 stop codons?

Answers

The amino acid sequence here is Met-Ser-Asp-Trp.  The start codon is AUG, while the three stop codons are UAG, UAA, and UGA.

The triplets of nucleotides or codons in mRNA determine the order of amino acids that will be added to the protein during translation.

The start codon in the genetic code is AUG and it encodes for the amino acid methionine (Met).

The 3 stop codons in the genetic code are UAG, UAA, and UGA. These codons do not code for an amino acid.

The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on
approximately 8300 lane miles of Maine's state roads. They usually plan on an average of about 30 treatable events in a winter. This
includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a
storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout
the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative
effects on plant life and aquatic ecosystems. What is something your community can try to reduce the environmental impact of

Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake.

Why can cells in the bone marrow produce both red and white cells

Answers

Answer:

1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.

Explanation:

2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.

3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

From when we are very little, we are taught to know the difference between right and wrong and how to follow rules. As we get older, rather than the rules that we followed as children, we learn to follow laws that allow us to function as adults in today’s society.

We are all probably familiar with traffic laws or laws about stealing or committing crimes, but did you know that there are laws and public policies written specifically for and about families?

If you didn’t already know about these particular laws, now is your chance to find out!

For this activity, you will be researching the various laws and public policies related to families. In addition, you will be creating several scenarios where these laws might come into play.

Activity Guidelines:
You will start by researching various laws and public policies that pertain to families. You can really take this research in any direction that you like, while keeping in mind that the ultimate goal will be to write five short scenarios and connecting each one to a different family law or policy. For example, you could write a scenario that involves a parent who is intentionally hurting their child and connect this scenario to a child abuse law.

Each scenario description should be no more than about one paragraph in length. You are welcome to include dialogue in your scenario or simply summarize and explain your scenario idea. After each scenario, you will write the specific family law or policy being broken in the scenario or how it otherwise pertains to the scenario. The name of the law or policy and a brief explanation of its connection to the scenario is all that you need to include.
