Blood pressure is directly proportional to vessel resistance. a. True b. False

Answers

Answer 1
Answer:

Answer:

False

Explanation:

Blood pressure is inversely proportional to vessel resistance
Answer 2
Answer:

Final answer:

Yes, it is true that blood pressure is directly proportional to vessel resistance. As vessel resistance increases due to narrowing of blood vessels, the heart has to exert more force, leading to an increase in blood pressure.

Explanation:

The statement that blood pressure is directly proportional to vessel resistance is true. Blood pressure is a measure of the force that your heart uses to pump blood around your body.

When vascular resistance (the resistance that must be overcome to push blood through the circulatory system and create flow) increases due to narrowing of the blood vessels, the heart has to work harder, which results in increased blood pressure. Therefore, it's a direct relationship: as vessel resistance goes up, so does blood pressure.

A group of college students working on a project on bio-gas have found some bacteria in the bio-gas plant. These bacteria can utilize methane as their source of energy and do not need oxygen for their survival. What kind of bacteria could they be?A- Archaebacteria
B- Eubacteria
C- Probacteria

Answers

The answer is (a.) Archaebacteria

Archaebacteria or Archaea are prokaryotes. They have no cell nucleus. They don't even have membrane-bound organelles in the cells. These bacteria can utilize methane as their source of energy but oxygen is not vital for their survival.

Which two microscopes generate three-dimensional images? scanning electron microscope and scanning tunneling microscope transmission electron microscope and scanning electron microscope scanning tunneling microscope and transmission electron microscope compound light microscope and scanning electron microscope.

Answers

The correct answer is scanning electron microscope and scanning tunneling microscope.  

The SEM refers to a kind of electron microscope, which generates three-dimensional images of a specimen by scanning the surface with a focused beam of electrons. The electrons associated with the atoms in the specimen, generating different signals, which comprise data regarding the composition of the specimen and the surface topography.  

An STM refers to an apparatus for imaging three-dimensional image surfaces at the atomic level. In this, good resolution is regarded to be 0.01 nm depth resolution and 0.1 nm lateral resolution.  

The STM can be utilized not only in a high-ultra vacuum but also in water, air, and numerous other gas or liquid ambient, and the temperatures spanning from 1000 degree Celsius to zero Kelvin.
