What happens when someone turns blue in the face?

Answers

Answer 1

When we loss color, it could be by an interruption of blood circulation. When we are very cold, for example when there is a blizzard, if we are not wearing proper clothes we will loss heat fast and our face and skin in general will turn blue or even purple. Also, when we loss oxygen income, for example when you can not breath, skin changes its color.

The Correct choice is ~

A. hypertonic solution

In a hypertonic solution, the concentration of liquid is higher in the solution as compared to that of concentration in the cytoplasm of cell, Therefore Osmosis takes place, causing the liquid present in the solution to move in the cell, and hence inflammation/ swelling occurs.

Convert enzyme concentrations of 2.5%, 5.0%, and 10% to ppt units.

Answers

Answer:

2.5 x 10¹⁰ ppt

5.0 x 10¹⁰ ppt

1.0 x 10¹¹ ppt

Explanation:

The notation ppt refers to parts per trillion units, that is, how many parts of enzyme are there in 1 trillion parts. Percentage refers to the number of parts per 100 units. Converting the given values from percentage to ppt:

\(\frac{2.5}{100}=\frac{a}{1,000,000,000,000}\\a=2.5 *10^{10}\ ppt\\\\\frac{5.0}{100}=\frac{b}{1,000,000,000,000}\\b=5.0 *10^{10}\ ppt\\\\\frac{10}{100}=\frac{c}{1,000,000,000,000}\\c=1*10^{11}\ ppt\)

The concentration in ppt are:

2.5 x 10¹⁰ ppt

5.0 x 10¹⁰ ppt

1.0 x 10¹¹ ppt

PPT means Parts per trillion.

The conversion rate from percentage to ppt is given as:

1 Percent [%] = 10 000 000 000 Parts per trillion [ppt]

1) Converting 2.5% to ppt

1%  = 10 000 000 000 ppt

2.5% = ?

Cross multiply

2.5% x 10 000 000 000 ppt / 1 %

= 25, 000 000 000 ppt

2) Converting 5% to ppt

1%  = 10 000 000 000 ppt

5% = ?

Cross multiply

5% x 10 000 000 000 ppt / 1 %

= 50, 000 000 000 ppt

3) Converting 10% to ppt

1%  = 10 000 000 000 ppt

10% = ?

Cross multiply

10% x 10 000 000 000 ppt / 1 %

= 100, 000 000 000 ppt

Calculate the population density of 900 sheep in a plot of land that is 3.00 km by 2.00km

Answers

The population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.

The population density of 900 sheep in a plot of land that is 3.00 km by 2.00 km can be calculated by dividing the total number of sheep by the area of the land.

First, we need to calculate the area of the land. The area can be found by multiplying the length and width of the plot of land:

Area = length × width = 3.00 km × 2.00 km = 6.00 km²

Next, we divide the total number of sheep by the area to calculate the population density:

Population Density = Total number of sheep / Area = 900 sheep / 6.00 km²

Performing the calculation, we find:

Population Density = 150 sheep/km²

Therefore, the population density of the 900 sheep in the given plot of land is 150 sheep per square kilometer.

Population density is a measure of the number of individuals (in this case, sheep) per unit area. By dividing the total number of sheep by the area of the land, we obtain the population density in terms of sheep per square kilometer. In this case, the population density is 150 sheep/km², indicating that there are, on average, 150 sheep within each square kilometer of the land.

Answer:

Toxic compounds can have a variety of effects on plankton. Depending on the type of toxic compound, plankton may be killed directly, or their growth and reproduction may be inhibited. Toxic compounds can also disrupt the food web by reducing the number of plankton available for other organisms to feed on. Additionally, toxic compounds can accumulate in plankton, making them toxic to other organisms that feed on them.

The honeybees vary slightly in color but are generally brown with bands of dull yellow and brown on the abdomen. Hair is abundant on the head, thorax, and abdomen. The legs and eyes are covered in hair. They live in large colonies led by a single queen.

By the third day, the egg is laid upright and falls to the side. The queen bee will lay both a fertilized egg and a non-fertilized egg, and the fertilized egg will develop into a female bee or queen bee. The non-fertilized egg will hatch and a male bee is born, also known as a drone bee.

Which statement about the relationship between interphase, the cell cycle, and mitosis is true?

A. The cell cycle and interphase make up mitosis.

B. Interphase and the cell cycle are parts of mitosis.

C. Mitosis and interphase are parts of the cell cycle.

D. Mitosis and the cell cycle are parts of interphase.

Answers

Answer: C.Mitosis and interphase are parts of the cell cycle.

Explanation:Interphase is actually the longest stage of the cell cycle. This is the point where the cell prepares itself for division. It is composed of 3 phases:

G1 phase - is when the cell starts to grow and copies its organelles.

S phase - it starts making copies of its DNA and makes a copy of its centrosome.

G2 phase - continues to grow and produces the proteins or enzymes that will be used in the process.

After the stage of interphase, the cell will enter its M phase or mitosis in the case of body cells. Mitosis is the process of cell division.

Despite the “blonds have more fun” myth, human hair color does NOT affect an individual’s survival or reproduction in any way. Thus, although it is evolving by all of the other forces, the evolution of human hair color is NOT being driven by the process of:

Answers

Natural selection. It does not give reproduction advantage. It doesn’t not provide “survival of the fittest” It was most likely a mutation that remained in the population

Thus, although it is evolving by all the other forces, the evolution of human hair color is not being driven by the process of natural selection.

What is natural selection?

Natural selection is the method by which a species adapts to its surroundings. Natural selection causes evolution when individuals with particular traits have a better chance of surviving than those who are not able to adjust to the changes, and these traits are handed on to succeeding generations.

Better-adapted organisms will live and procreate through a process called natural selection. This indicates that this mutant organism's favorable alleles are handed on to progeny. Natural selection over many generations causes evolution to take place.

Thus, despite being influenced by all other variables, natural selection is not the primary cause behind the development of human hair color.

Consider an experiment in which nucleic acids are separated using agarose gel electrophoresis. In the gel you load the following samples: Lane 1: a population of linearized 3000-bp double-stranded DNA (dsDNA) molecules. Lane 2: a population of circular 3000-bp double-stranded DNA (dsDNA) molecules. Lane 2: a population of circular 3000-bp double-stranded DNA (dsDNA) molecules Which population of nucleic acids would most likely migrate through the gel fastest, and in which direction through the gel will these molecules migrate?

a. The linearized dsDNA would most likely migrate faster than the circular dsDNA. All DNA molecules would migrate toward the positive end of the gel.
b. The circular dsDNA would most likely migrate faster than the linearized dsDNA. All DNA molecules would migrate toward the positive end of the gel.
c. The circular dsDNA would most likely migrate faster than the linearized dsDNA. All DNA molecules would migrate toward the negative end of the gel.
d. The linearized dsDNA would most likely migrate faster than the circular dsDNA. All DNA molecules would migrate towards the negative end of the gel.

Answers

Answer:

a. The linearized dsDNA would most likely migrate faster than the circular dsDNA. All DNA molecules would migrate toward the positive end of the gel.

Explanation:

Electrophoresis gel is a technique widely used in molecular biology in order to separate macromolecules (e.g., DNA, RNA, proteins) according to their size and charge. The DNA is a molecule negatively charged, thereby the DNA fragments will always move toward the positive electrode in an electrophoresis gel. In the DNA molecule, the charge-to-mass ratio remains constant, thereby DNA fragments will separate based on their size (i.e., small DNA fragments will move through the gel faster than large ones). Moreover, for the same size, linear dsDNA fragments experience less frictional resistance against the gel than circular dsDNA fragments and, therefore, linearized dsDNAs run faster.
