For #1, the last choice is correct. A geocentric model means that the earth is the center of the universe while all other bodies orbit around it. A heliocentric model means that the sun is the center of the inverse while the other bodies orbit around it. The shared feature is that the other bodies in space move in circular orbits.
For #2, the first answer is correct. When the moon is between the earth and the sun, positions X and Z are being pulled by the moon’s gravitational force, creating high tides at these places. However, positions W and Y are experiencing low tides because no gravitational pull is making them high.
The Convection currents do produce the heat in the Earth’s interior. So its true
There are four types of sensory receptors that respond to one of the four primary stimuli.
Thermoreceptors detect temperature changes in the environment.
Mechanoreceptors detect changes in pressure
Photoreceptors detect the photons composing light
Chemoreceptors detect chemical stimuli and are found inside the body (for example blood vessels). They are also responsible for our sense of taste and smell.
Thus, the correct answer to the question is D. on the tongue and in the nose, to detect taste or odor.
Your genotype would be both upper case. It would look like RR.
