1 answer:

3 0

1. In the configuration of the chicken wing, a connective tissue acts as an anchor. The connective tissue connects the muscle to the bone. This tissue is called the tendon.

2. The rile between muscles, tendons, bones, ligaments, cartilages and joints is that they all act simultaneously to make movement possible for a certain body. It may also be that they are not quite very distinguishable between each other, making one think that one is the other.

Explain the significance of meiosis in sexual reproduction

iogann1982 [59]

Answer: Meiosis produces the sex cells, that is the gametes (sperm cells and eggs) that unite to form a zygote. Meiosis ensures that the gametes have have haploid chromosomes so that the resulting zygote from their fusion will have diploid chromosomes.

Explanation: Meiosis is a type of cell division in which a cell divides twice to produce four daughter cells each with the half the number of chromosomes as the parent cell. Without meiosis new gametes are not produced. Meiosis ensures that the chromosomes are evenly distributed among the daughter cells and that each daughter cell contains 23 chromosomes. A sperm cell with 23 chromosomes fuses with an egg with 23 chromosomes to form a zygote with 46 chromosomes. If meiosis does not occur, gametes with haploid chromosomes will not be produced, and if the gametes have diploid chromosomes because meiosis does not occur, sexual reproduction will be a disaster because when two diploid gametes fuse the resulting zygote with be abnormal.

mezya [45]

Answer:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Explanation:

The microscope is an essential equipment used in science laboratories to view objects which are too small to be seen by the naked eye. Also certain processes which occur at the microscopic level can only be observed using a microscope.

There are many different types of microscopes. The compound light microscope is the one most commonly used in biological laboratories to view tissues and cells of organisms. It uses visible light which passes through two separate lens to magnify the image produced of a specimen.

The various parts of compound light microscope and their respective functions are given below:

Adjustment knob (coarse) ---> Causes stage (or objective lens) to move upward or downward

Arm ---> Serves as a handle for carrying the microscope

Condenser ---> Concentrates light onto the specimen

Eyepiece (ocular) ---> Contains a lens at the top of the body tube

Field of view ---> Circular area seen through the eyepiece

Iris diaphragm ---> Increases or decreases the light intensity

Nosepiece ---> Part to which the objective lenses are attached

Objective lens system ---> After light passes through the specimen, it next enters this lens system

Stage ---> Platform that supports a microscope slide

Stage (slide) clip ---> Holds a microscope slide in position

The question is incomplete,below is the complete question.

Mr. B has been transferred to your floor to wait and see whether the chest tube allows his lungs to completely re-expand. But when he arrives, he is in severe respiratory distress. He says "I felt better before I came into the ER! Is this tube doing anything?"

You tell the Clinical Nurse Specialist (CNS). As the two of you move him into the bed, you notice that his chest tube bottle is lying on its side on the gurney, with air going into it. When you point this out to the CNS, she immediately grabs the bottle and sets it upright on the floor. You see air start bubbling through the fluid right away. "That was the problem!" she says. "They lost the water seal, and air was going into his chest from the bottle. You would not believe how many times that happens on transport." When you examine Mr. B, you have trouble detecting his lung sounds on the left. Even stranger, his apical heart sound is in the wrong place - it is over toward the right side of his chest. His respiration rate and heart rate are both increased, and he is struggling to breathe. "Let's give him a little oxygen. He'll be a lot better in a half-hour," says the CNS. "Check back on him."

QUESTION - Why would accumulation of air in his pleural space cause his heart sounds to be in the wrong place?

Accumulation of air in Mr B pleural space will cause his heart sound to be heard in the wrong place because the left side is his chest is being filled up with air making the organs in his chest to to be pushed over to the right side.
