Example of chemical energy being converted to mechanical energy.

1 answer:

4 0

For example, an internal combustion engine converts the potential chemical energy in gasoline and oxygen into thermal energy which, by causing pressure and performing work on the pistons, is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy).

I hope this is what you need. :)

A newborn baby dies soon after birth because her diaphragm and rib cage muscles failed to contract and she was unable to breathe

kozerog [31]

Answer:

Troponin

Explanation:

This is a complex of three proteins (Trop C, I, T) that are responsible for muscle contraction of the skeletal and cardiac muscles . its binds with protein tropomysin to lie in the grove between the actin filaments. its prevents contraction by blocking myosin crossbridge in a relax muscles.Inorder to aid contractions calcium ions binds with troponin, which leads to confrontational change.This exposes myosin on actin filaments, leading to formation of crossbridge and therefore contraction of muscles.

Therefore if there is a mutation in the gene that encoded Troponin, as explained above, calcium ion will not be able to bind with tropinin, and there will be no exposure of myosin on actin filaments, no binding of myosin on actin to cause crossbridge, and consequently no muscle contraction,

Thus the intercoastal muscle and diaphragm will not contract leading to death of the baby.

Systolic blood pressure:_____________ a) is the higher number of a blood pressure reading. b) is the lower number of a blood pre

Alik [6]

Answer:

is the higher number of a blood pressure reading.

Explanation: systolic blood pressure is the higher number of a blood pressure reading and its measure in millimeter of mercury.

Systolic pressure is the amount of pressure in the arteries when contraction takes place in heart. Diastolic pressure is the pressure the heart when it relaxes. It is the lower number of blood pressure reading

When the systolic pressure is >120mm Hg and diastolic is less than 80mm Hg it is normal

120-129mm Hg and diastolic less than 80mm Hg it high and such person needs a regular medical check up

But when systolic 129-139 mmHg

and diastolic is 90mm Hg or above it means the individual is having hypertension stage 1

Above 140mm Hg is hypertension stage 2 and it is the most severe stage. It means the person is hypertensive and medical attention needs to be seek for necessary treatment as this could lead to death of such individual if not well managed.

In what generation does this population reach its carrying capacity

Katena32 [7]

Answer:

The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.

Granulocytes are which type of cell?

Olin [163]

Answer:

The correct answer will be option- leukocyte.

Explanation:

The granulocytes are the cells which contain secretory granules in its cytoplasm. The granulocytes are a part of the white blood cells or "leukocytes" which provide immunity to the organism.

The granulocytes are of three types called mainly the neutrophil, basophil, or eosinophil which provide immunity by ingesting the foreign material and digest the invading microbes by the action of enzymes produced by the granules in the cytoplasm.

Thus, option- leukocyte is the correct answer.
