Answer:
Stage 2 hypertension
Explanation:
Hypertension is a body circulatory system condition whereby the pressure of the blood vessels are raised persistently. The heart pumps blood to the different organs of the body through the blood vessels, each time it beats
The normal blood pressure in the vessel = 90/60 mmHg to 120/80 mmHg
The blood pressure of a prehypertension person or person at risk of having hypertension = 120-139/80-89 mmHg
The blood pressure at Stage 1 hypertension = 140/90-99 mmHg
The blood pressure at Stage 2 hypertension = 160/100 mmHg.
Answer;
-Endoplasmic reticulum
Explanation;
Molecules produced in the nucleus are transported to the cytoplasm via endoplasmic reticulum.
-Endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins.
It is an interconnected network of flattened sacs or tubes encased in membranes. These membranes are continuous, joining with the outer membrane of the nuclear membrane. It works closely with the Golgi apparatus, ribosomes, mRNA, and tRNA.
Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.
