Answer:

The correct answers are organs mouth and stomach.

Explanation:

The organs, which do both mechanical and chemical digestion are the mouth and the stomach. Both these organs are the components of the digestive tract. In the mouth, the mechanical digestion occurs through chewing, on the other hand, the chemical digestion begins in the mouth as a consequence of the enzymes lipase and amylase.  

In the stomach, the mechanical digestion takes place by churning, and the chemical digestion is performed by the enzyme protease.

Answer: Mouth.

Explanation:  

The mouth is known to be performing both the tasks of chemical digestion and mechanical digestion.

The food is ingested through mouth and the teeth perform the process of mechanical digestion by breaking down the food particles into smaller particles.

Then the saliva gets mixed into the food and the enzymes(amylase) present in the saliva helps in the digestion of carbohydrates.

So, mouth is the organ that performs the process of both mechanical and chemical digestion.

<h3>What is the normal blood pressure?</h3>

The blood pressure refers to the rate at which the heart pumps blood to the other parts of the body. The blood pressure would rise if the blood vessels are blocked and the heart would have to do more work to pump blood.

The measurements that are normal for a client is a blood pressure of 108/80, a pulse of 112 beats per minute and respiratory rate of 15 breaths per minute.

<h2>Answer:</h2>

The correct statement is option A which is, "A gene is a segment on the DNA. DNA is wrapped in proteins to form a chromosome".

<h3>Explanation:</h3>
  • A gene is the part of DNA in the nucleus which encodes for the specific trait in the body. DNA is the nucleotide sequence which is the blue print for the whole organism. It contains genes for all the structures and functions in the body.
  • So it is very long sequence containing the million of genes. So in nucleus it is present in compress form. It is wrapped on the histones proteins and condense and supersondense into a specific structure which is known as chromosome.

Each ABO blood group is associated with the presence/absence of RBC antigens and the presence/absence of antibodies in the plasm
harina [27]

Answer:

a. Type O blood - No A or B antigens on RBCs-Anti-A antibodies in plasma-Anti-B antibodies in plasma

b. Type A blood - A antigen on RBCs- Anti-B antibodies in plasma

c. Type B blood - B antigen on RBCs- Anti-A antibodies in plasma

d. Type AB blood - A antigen on RBCs- B antigen on RBCs- Neither anti-A or anti-B in plasma

Explanation:

ABO blood grouping system represents multiple allelism which was discovered in humans by Karl Landsteiner. The blood group is determined by the presence or absence of A & B antigens and antibodies.

The 4 blood groups which exist in ABO system are O, A, B and AB. Also, allele A and B are co-dominant i.e. if they both will exist on the surface of an RBC then both will be equally expressed which implies that there will be no dominant or recessive allele.

Type O blood group has H antigen on the surface of RBC and has both the antibodies i.e. antibody A and B. The absence of antigens A and B makes it a universal donor.

Type A blood group has A antigen on RBC and has antibody B in the plasma.

Type B blood group has B antigen on RBC and has antibody A in the plasma.

Type AB blood group has both the antigens i.e. antigen A and B on RBC and does not have any antibody in the plasma which makes it a universal acceptor.
