Answer:
i think the answer should be b.
the alveolus is the site of exchange of gases (carbon dioxide and oxygen) between the body cells and the alveolar air. diffusion requires a concentration gradient, which basically means that there has to be a difference in concentration of the substance (in this case it's oxygen) between the 2 areas (in this case it's the body cells and the alveolar air) hence, there is more oxygen in the alveolar air than the body cells (this difference in concentration is what allows diffusion of oxygen from a region of HIGHER to LOWER concentration!) this allows oxygen to diffuse from alveolus to body cells, giving your body the oxygen it needs!
btw keep in mind that i am by no means an expert in biology (because im still a student), but b is the most logical answer to me. good luck!

1.) Using the information in the table below, determine the amino acid sequence or get is coded for by the mRNA sequence: AUG-UCU-GAU-UGG-UAC.
2.) What is the start codon? What are the 3 stop codons?
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.

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.hope it helpsWhat type of cells do humans have prokaryotic or eukaryotic?

A rat has 42 chromosomes in eath somatic call. How many chromosomes are in each gamete
Answer:
21 chromosomes
Explanation:
Somatic cells are a diploid which have 2 sets of chromosomes. If two sets are 42 chromosomes, one set must be 21 chromosomes. Gametes are a haploid which have only 1 set of chromosomes. So in each gamete, there should be 21 chromosomes.

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
salting? Select ALL that apply.
A)
Buy more snow plows and use less salt.
B)
Ban all salt based solutions in the state.
C)
Provide incentives to consumers who install snow tires for increased
traction.
D)
Provide tax incentives to municipalities who will install solar panels that
heat water in pipes embedded in the road.
Wet the pavement before applying brine solutions to help the salt adhere
to the road, cutting back on how much they use.

1. Why does the angle of the sun at noon seem to change at different months throughout the year?
2. How does this create seasons?
Answer:
1. The earth orbit is slightly elliptical, and the earth axis is tilted by roughly 23.5° to the orbit. These to factors combine to make the an analemma. But in the winter, When the Earth is on the other side of orbit, the Earth's north pole is tipped away from the Sun, so at noon the sun doesn't get as high.
2. The earth's spin axis is tilted with respect to it's orbital planet. This is what causes the season. When the earth's axis points towards the sun. it is summer for that hemispheres. Midway between these two times in spring and autumn, the spin axis of earth points 90 degrees away from the Sun.

Answer:
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. The earthquake starts at the focus, with slip continuing along the fault. The earthquake is over when the fault stops moving.

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

Which term is credited to Hooke's scientific research?
Answer:
Cell
Explanation:
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.
WILL MARK BRAINLY-IST
A basic template is included below. Feel free to use it or create your own in a word processing or slideshow program.
Your grade will be based on creating all five scenarios and your ability to connect each one to a different family law or policy. For further details on how you will be graded, see the rubric below.
