Carson divided 40 unripe bananas evenly among eight paper bags and sealed the bags. He poked 20 small holes in four of the bags

and left the other four without holes. He kept the bags at room temperature for three days. Then, Carson opened the bags and counted the number of brown spots on each banana. He compared the average number of brown spots on bananas from bags with holes to the average number of brown spots on bananas from bags without holes.Identify the question that Carson's experiment can best answer.

Answer:

See the answer below

Explanation:

From the illustration of the experiment, the question that Carson can best answer  is that<em> "Do bananas develop more brown spots if they are kept in bags with holes  compared to bags without holes?"</em>

The independent variable in the experiment is the hole poked in the bags while the dependent variable is the number of brown spots on each banana. The difference between the subjects is the hole poked in the bags, hence, any difference in the number of brown spots between bananas in the bags with holes and those in the bags without holes can be attributed to the hole poked in the bags.

<u>Therefore, the question that can be answered from the experiment is to see if poking holes in bags make bananas to develop more brown spots compared to bags without holes. </u>

What is on a transplanted organ that causes the transplant recipient's body to reject it?
Delvig [45]

Answer:

Major histocompatibility complex (MHC) antigens

Explanation:

The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.

A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the  transplanted organ.

Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

How does using a ramp make work easier when loading a piano onto a truck three feet above the ground
goblinko [34]
<span>The ramp on an automobile transport truck is used to lift cars high into the air. An inclined plane makes it easier to raise something heavy, like a rock. Instead of lifting the rock straight up, you can raise it from its original location with less force by pushing it up a ramp.</span>

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.
Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

           Number of protons = 8

           Number of neutrons = 8

          Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

    To calculate the mass defect, we first know the mass of the nucleons first:

           1 proton has a mass of  1.00728amu

           8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

          1 neutron has a mass of 1.00866amu

          8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

                                   = 8.05824amu + 8.06928amu

                                   = 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

                             = 16.12752amu - 15.994914amu

                              = 0.132606amu ≅ 0.13261amu to 5 decimal places
