Explanation:
Generally, a small difference in blood pressure readings between arms isn't a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem
.A significant difference in the pressure recorded in the right and left arms can signal circulatory problems that may lead to stroke, peripheral artery disease, or other cardiovascular problems.
They are the primary producers
Answer:
Intensity of heat, lack of water, and a blazing/searing sun.

Why are there so few humans and animals in the desert?</h2>
A desert is defined as a place with a hot and dry temperature, little or no rainfall (less than 25 cm), a barren landscape, a lack of water, and dry soil. There is very little vegetation. Plants appear only after rain, are seasonal, and have a short lifespan. Dust storms and shifting dunes may be dangerous. In other words, the circumstances are unfit for human occupancy. That is why relatively few people live in or near deserts. Animal life is likewise sparse, yet abundant in some areas. Some locations, such as Egypt's Nile Valley, may be heavily inhabited if enough water is available. In reality, air-cooling, air-conditioning, and irrigation facilities, as well as the discovery of petroleum wherever and whenever it was accessible, have made desert life more pleasant, dynamic, and have drawn people from outside, such as the Gulf area.
<h2>Why don't desert animals just move somewhere greener?</h2>
Deserts are a result of the Earth's atmosphere. Do you notice how deserts appear to be in similar zones? This is due to the tight link between deserts and rainforests. So this is what generates a desert, not what attracts or maintains animals here. Plants bring them and keep them alive. As plants adapt, so do animals, and the desert creates a complete ecosystem. They do not depart since they have adapted to their surroundings.
Answer:
Constrained by the extent of existing knowledge - Developing a hypothesis and designing an experiment is based on current human knowledge. Design of experiment is limited to observation method and instrument - e.g. discovery of viruses depended on the discovery of the electron microscope. Human error - e.g. mistakes can occur in recording observations or inaccurate use of measuring instrument.
Deliberately falsifying results - i.e. scientific fraud. Bias - prior confidence in the hypothesis being true/false can affect accuracy of observation and interpretation of results.
