In 1907, Dr. Duncan MacDougall performed a series of experiments in which he attempted to measure the weight of the soul as it left a dying person. In his experiments, MacDougall placed a dying person on a scale and measured their weight immediately prior to and following death. MacDougall determined the change in weight to be approximately 21 grams. From these experiments, he concluded that the soul exists and has mass. What is the fundamental scientific flaw in his conclusions? (5 points)

They are based on the concept of the soul, which is beyond the bounds of science.
They are based on the idea that the soul is made of matter, not energy.
They are based on the assumption that the soul does not remain in the body after death.

D. O protein chains are composed of amino acids, and carbohydrate chains are composed of sugars.

Answers

The answer is D. protein chains are composed of amino acids, and carbohydrate chains are composed of sugars.

Both protein and carbohydrate molecules tend to form chains. These chains differ in that protein chains are composed of amino acids, and carbohydrate chains are composed of sugars. Thus, option D is correct.

What is protein?

Protein has been defined as the large macromolecules as well as biomolecules that are used to made up of the long chains of the amino acid. There has been various function of the protein such as the DNA replication, speeding up of chemical reaction which helps to maintain the structure of cell.

The main function of the protein has to maintain the structure and function of the organs, repair muscle, and the muscles. Diet contains high protein has been recommended for the purpose of losing weight, reducing fat, or increasing fat.

There are several types of the protein such as the structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.

Therefore, Both protein and carbohydrate molecules tend to form chains. These chains differ in that protein chains are composed of amino acids, and carbohydrate chains are composed of sugars. Thus, option D is correct.

Hydras are animals related to coral and jellyfish. Hydras can reproduce sexually or asexually. Why would hydras avoid reproducing asexually when conditions are difficult?
1. The high genetic diversity could mean that all of the hydras die, depending on the situation.

2. The lack of genetic diversity could mean that all of the hydras die, depending on the situation.

3. Reproducing more slowly would be a good way to take advantage of plentiful resources.

4. Reproducing more rapidly would be a good way to take advantage of plentiful resources.

Answers

Answer: 3. Reproducing more slowly would be a good way to take advantage of plentiful resources.

Explanation:

Hydra reproduce by both sexual and asexual modes of reproduction. In the case of asexual reproduction the bud develops on the parent body and derives nutrition from parent body, matures and finally get detached from the parent body. During asexual reproduction many buds will develop and live as an individual organism this will reduce the availability of resources like habitat, food, and others. Thus if the organism reproduces slowly then it will take advantages of many resources without experiencing the scarcity of resources.

Which of the following statements is true for a molecule that is phosphorylated?
A) It has been reduced as a result of a redox reaction involving the loss of an inorganic phosphate.
B) It has a decreased chemical energy and is less likely to provide energy for cellular work.
C) It has been oxidized as a result of a redox reaction involving the gain of an inorganic phosphate .
D) It has increased chemical potential energy that may be used to do cellular work.

Answers

Answer:

The correct appropriate is Option D.

Explanation:

The phosphorylation mechanism of both a chemical compound, either through inorganic phosphate conversion other than by phosphate conversion from yet another biological phosphate.  Those have improved chemical energy capacity which could be used to do cellular function.  

Some other possible alternatives are not connected to the situation described. So, the solution above is the right one.

The statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).

Phosphorylation is a posttranslational protein modification that plays a fundamental role in many cellular processes.

Phosphorylation increases the potential energy of a molecule by adding a phosphate group that contains a high-energy phosphate bond.

The energy released by this phosphate bond can be used to drive many cellular processes.

In conclusion, the statement 'it has increased chemical potential energy that may be used to do cellular work.' is TRUE about a molecule that is phosphorylated (Option D).

Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body

Explanation:

Answer:

A group of disorders that cause red blood cells to become misshapen and break down.

Explanation:

With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anemia), and can block blood flow causing pain (sickle cell crisis).Infections, pain, and fatigue are symptoms of sickle cell disease.

Which of the following best describes how the structure of the fluid mosaic model of the cell membrane controls the movement of substances in and out of the cell? (3 points)

Answers

Answer: The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.

Explanation:

The option that describes the fluid mosaic model of the plasma membrane is a lipid bilayer with protein molecules dispersed within it.

It should be noted that the fluid mosaic model of the plasma membrane was proposed by Singer and Nicholson to explain the structure of the plasma membrane.

The plasma membrane is known as a fluid model because it has several types of molecules that float along the lipids. The fluid mosaic model of the plasma membrane is made up of two layers of lipid molecules where there are protein molecules dispersed within.

which of the following determines the identity of an element?
a. atomic number
b. mass number
c. atomic mass
d. overall change

Answers

A. The atomic number

The identity of any element is given out by the atomic number it carries thus every element has different atomic number. The correct answer is option A.

What does atomic number signify ?

It signifies the number of electrons and the number of protons which are present in any element as the atomic number is equal to the number of electrons and the number of protons as well.

Atomic number is a unique property that is given out to element where the basis of their characters and the properties signifies their basic characters on which the elements will align themselves for example the elements having the atomic number as the 1 at the end usually has 1 electron in their last atomic shell same for 2.

On the basis of their properties elements are divided into various groups where the 1st one is called as alkali metal and the 2nd one is called as alkaline earth metals, 17 is called as halogens and the last 18th is called as noble gases.

What does a high population density indicate?

O The area is being overfished.

O The species is likely to face extinction.

O There is no other place for that species to live.

O Food supply is high and the number of predators low.

Answers

Answer:

O Food supply is high and the number of predators low.

Explanation:

Population density is defined as the population living in per square mile/km.

High population density indicate that the people living in an area have high food supply and the number of predators low. Predators are responsible to control the population but due to high food supply and low predators, there will be no control in the population and no control in the feeding behavior of the population that leads to High population density.

Hence, the correct option is "Food supply is high and the number of predators low."

Answer:

D; Food supply is high and the number of predators low.
