A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases

Answers

Answer 1

Answer:

A.Blood volume decreases

Explanation:

Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.

Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.

This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.

Answer:

The main role is to filter blood coming from the digestive tract before it passes through the rest of the body. The liver can also detoxify or remove toxic chemicals like drugs and metabolize them.  The liver then creates bile that ends up back in the intestines.

Answer:

Light dependent reactions

Explanation:

DPIP stands for Dichlorophenolindophenol. It is a chemical compound that is used as a redox dye.

DCPIP is blue when it is oxidized DCPIP is colorless when it is reduced.

DCPIP measures the rate of photosynthesis. The redox dye is decolorized by chemical reduction when it is exposed to light in the process of photosynthesis.

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria

Answers

Answer:

A.The bacteria in the culture tube were already dead when you made the plate

Explanation:

Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.

Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.

There can be several interpretation for the absence of bacteria such as:

The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.

Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.

Answer:

The correct answer is:

The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.  (d.)

Explanation:

Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.

The various types of endocytosis has a common feature of:

1. invagination of plasma membrane forming pockets around the target particle.

2. the pocket pinches off from original plasma membrane

3. forming a new intracellular vesicle containing the target particle.

The different types of endocytosis includes

a. pinocytosis (cell drinking): takes in extracellular fluids

b. phagocytosis (cell eating): large solid particles are taken in by cells

c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.
