Answer: Option B) Antigens

Blood typing is based on the presence of proteins known as antigens on the outer surface of the red blood cell plasma membrane.

Explanation:

Blood groups A, B, AB, and O are determined based on the antigen-antibody reactions between donor and recipient bloods.

For instance,

- Blood type A has antigen A on its plasma membrane

- Blood type B has antigen B on its plasma membrane

- Blood type AB has both antigen A and antigen B on its plasma membrane

- while blood type O has neither antigen A nor B on its plasma membrane

So, antigens is the answer

Based on the text, why might the California's Division of Safety of Dams have
Vikki [24]

Answer:

The correct answer is A)

To limit the potential flooding damage that could result if an  earthquake happens and the dam spills over

Explanation:

According to the text, seismic risks are very high for dams in that region. One of the reasons is that some of the dams were built many years ago when civil engineers didn't have information about what an earthquake could do to dams.

Citing an occurrence that happened in 1899 as an example where thousands of people were killed as a result of a failed dam, it is feared that should same reoccur, the loss may be more because about 300,000 people occupy the flood zone along the Alameda Creek below the dam.

Cheers!

During glycolysis, glucose is broken down into two molecules of pyruvate.
mojhsa [17]

Answer:

<em><u>Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.</u></em>

Explanation:

Glycolysis is an oxidation reaction in which glucose reacts with oxygen molecules and oxidized. By oxidizing glucose, it produces pyruvate, adenosine triphosphate (ATP) and nicotinamide adenine dinucleotides (NADH). Glycolysis has two phases. In the first phase, 2 ATP molecules are invested for the phosphorylation of glucose to break down into a simpler one. In the second phase of glycolysis, 4 ATP molecules are earned back with 2 NADH and a simpler form of glucose (6C) to pyruvate (3C) by oxidizing glucose.

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for
svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

      F = m  x   a

F = force on body

m = mass of body

a = acceleration of the body

 But we know that acceleration is the change in velocity with time of a body;

     a  = \frac{change in velocity }{time}

  F = m x \frac{V}{t}

V is the velocity

t is the time taken

   F = \frac{75  x  4.4}{3.1}   = 106.5N

Plants, algae, and many single-celled organisms can photosynthesize using a specialized cell organelle called a chloroplast. Do
Dovator [93]

Answer:

Yes

Explanation:

<em>The chloroplast is an organelle through which photosynthesis takes place. While the light reaction takes place in the thylakoid membrane of the chloroplast, the light-independent reaction or the Calvin cycle takes place in the stroma of the chloroplast. </em>
