Answer:
C but Humans burning fossil fuel is number 1
Answer with Explanation:
Let's start first with water on the Earth's moon. This is called "lunar water."
The moon was thought to be barren by scientists long time ago. However, they found out that there are actually <em>water reserves located in the shadowed craters.</em> It is said that the formation of this water was possible with the existence of <u>Oxygen atoms in the lunar rocks and minerals. </u>Due to the <u>solar wind</u> that blew into the place, <u>the Hydrogen ions from the wind combined with the Oxygen in order to form water.</u> So, the water that is found here is relatively fresh.
Let's go to "water on Mars." This is said to be <em>more older than the water on the moon</em> and is actually not that pure for it consists of some mixtures of rocks. It is said that billions of years ago, Mars had an abundant supply of water, but due to climate change, the supply didn't last long. As a result, the planet dried out and only the areas in the polar and mid-latitude regions have water<em> (in the form of ice).</em> This ice melts and refreezes, depending on the temperature. This is an evidence that people may possibly live on Mars.
Answer:
it is because glands are not from outer body coordination
Explanation:
brain,motor neuron,movement,etc are components that involve in coordination like when somebody accidentally touches a hot surface or hear the sound of the door bell

glands synthesis hormones that help keep the body in optimal condition

Process A likely describes a photosynthesis whilst process B describes respiration.
Answer:
Option-C
Explanation:
Hamilton gave the mathematical expression for the altruistic behaviour or trait in a population which suggested that the alleles for altruistic behaviour will be favoured by the natural selection if BR-C > 0.
The mathematical expression for the altruistic trait is rb> c
where r - relatedness, b- the benefit to recipient and itself also and c-cost to an actor.
In the given question, all the cases meet the condition of Hamilton's rule except one which is the In- law bee-eaters which raise the young near to the nest as the parents who can raise the young ones are not benefited personally from the action of the young as the young one treat them as non-kin. This does not fulfill the condition of the Hamiltons rule.
Thus, Option-C is correct.
