How are oxygen and carbon dioxide exchanged between the alveoli and the
capillaries?
A. Endocytosis
B. Osmosis
C. Simple diffusion
5
D. Active transport

Answers

Answer 1

Answer:

B. Osmosis

Explanation:

Osmosis is the process in which oxygen and carbon dioxide exchanged occur between the alveoli and the  capillaries because the oxygen enters the body and the carbondioxide gas leaves the cell through a semi-permeable membrane and we know that Osmosis is a process in which smaller molecules moves from higher concentration to lower concentration through semi-permeable membrane of the cell.

A distribution of class scores on a test is approximately normal with a mean of 75 and a
standard deviation of 8. Edna scores an 85%. Does her score place her in the top 10% of
this class?
O A. No, 10.6% of the class scored above her test score
B. Yes, 10.6% of the class scored above her test score
C. No, she scored better than 10.6% of her classmates
D. Yes, less than 10% of the class scored better than her test score

Answers

Answer:

O A. No, 10.6% of the class scored above her test score

Explanation:

Using the standard normal distribution (Z score) to solve this problem. The formula is as follows:

Z = x - μ/σ

Where;

σ = standard deviation

μ = mean score

x = Edna's score

According to the information given in this question:

σ = 8

μ = 75%

x = 85%

Z = 85 - 75/8

Z = 10/8

Z = 1.25

Using the table of normal distribution probabilities, we check for Z score of 1.2 under 5 = 0.8944

This means that Edna's percentage score is 89.44%. Hence, (100 - 89.44) = 10.56% is above Edna's score in the class

Approximately, 10.6% of the class scored above Edna's test score, meaning that she is not among the top 10% of her class.

The correct order of the Earth's mechanical and compositional layers is as follows:

Compositional: crust, mantle, core. Mechanical: lithosphere, asthenosphere, mesosphere. Option B is correct.

The Earth's mechanical layers are defined by their physical properties, such as their rigidity and strength. The compositional layers are defined by their chemical composition.

The Earth's mechanical layers are:

Lithosphere: The outermost layer of the Earth. It is the rigid, solid outer layer that includes the crust and the uppermost part of the mantle.Asthenosphere: The layer below the lithosphere. It is a hot, soft layer of rock that can flow slowly.Mesosphere: The layer below the asthenosphere. It is a solid layer of rock that is denser than the asthenosphere.

The Earth's compositional layers are:

Crust: The outermost layer of the Earth. It is the thin, solid outer layer that includes the oceanic crust and the continental crust.Mantle: The layer below the crust. It is the thickest layer of the Earth and is made up of hot, solid rock.Core: The innermost layer of the Earth. It is made up of two parts: the outer core, which is liquid, and the inner core, which is solid.

What happens when a cycle res turns to its starting point

Answers

Explanation:

Now that we’ve learned how autotrophs like plants convert sunlight to sugars, let’s take a look at how all eukaryotes—which includes humans!—make use of those sugars.

In the process of photosynthesis, plants and other photosynthetic producers create glucose, which stores energy in its chemical bonds. Then, both plants and consumers, such as animals, undergo a series of metabolic pathways—collectively called cellular respiration. Cellular respiration extracts the energy from the bonds in glucose and converts it into a form that all living things can use.

All living things must grow and develop. Which of the following choices is an example of this?

The two types of cells will produce roughly equal amounts of Sendai virus.

Answers

Answer:

The correct answer is - a. Cells expressing more NS3/4a will produce more Sendai virus than cells that do not express NS3/4a.

Explanation:

NS3/4a is a multiprotein serine protease that is a non-covalent heterodimer consisting of a catalytic subunit protein. This heterodimer has an N-terminal one-third of NS3 protein and at an activating cofactor (NS4A) protein.

It acts as an antagonist for cytokine promoters. Thus in the absence of cytokines or reduced levels of cytokines due to inactive promoters) the expression of the virus would increase.

Most individuals diagnosed with type 1 diabetes have an increased probability of having inherited the disease from both parents. additionally caucasians have the highest diagnosed rate of type 1 diabetes what can you conclude from this information
(a) type 1 diabetes risk factors are likely more prevalent in caucasians than in other races; (b) type 1 diabetes is easily cured in caucasians;
(c) type 1 diabetes risk factors likely influence the risk factors for type 2 in caucasians; (d) type 1 is treated most easily in caucasians

Answers

Answer:

(a) type 1 diabetes risk factors are likely more prevalent in caucasians than in other races

Explanation:  

Both diabetes types, I and II, have different origins. However, they share the fact that people inherit only the predisposition of developing the disease and that the environmental conditions might trigger the expression of the disease. The final result is hyperglycemia and the risk of developing chronic microvascular and macrovascular complications.

In the case of Diabetes I, both parentals must provide the genes to the child. This is, the predisposition of getting the disease must be inherited from both parents.

It is suggested that white people express most commonly Diabetes 1, making it more common in caucasian people that show the highest rate of affection.

So to express diabetes 1, white people need to inherit the genes from both parents, but also they must be exposed to conditions that provoke the expression of diabetes. Environmentally, different factors might influence, such as weather, feeding habits, viruses, among others.

Answer:

100% of children will have a double heterozygous genotype (EeWw)

Explanation:

A homo-zygous individual is an individual that has two dominant alleles or two recessive alleles for a given gene/locus. A dihybrid cross, also known as Mendelian dihybrid cross, refers to a type of cross in which both parents differ in two observed phenotypic traits which are controlled by two distinct non-linked genes. When both parents are inversely homo-zygous for both genes as in this case (i.e., one parent is homo-zygous dominant for the first gene and homo-zygous recessive for the second gene, while the other parent is homo-zygous recessive for the first gene and homo-zygous dominant for the other), all the F1 will be heterozygous, i.e., all F1 individuals will have the EeWw genotype because each parent can produce only one type of gamete (either Ew or eW). If both genes are subject to complete dominance, then the expected phenotypic ratio of the F2 obtained by crossing double heterozygous individuals will be 9:3:3:1, i.e., 9/16 individuals will have the dominant phenotype for both traits (in this case E_W_ genotype), 3/16 individuals will have the dominant phenotype for the first trait (in this case, dominant earlobe E_ww genotype), 3/16 individuals will have the dominant phenotype for the second trait (in this case, dominant hairline eeW_ genotype), and 1/16 will have the recessive phenotype for both traits (in this case, double recessive eeww genotype).
