The correct answer is option a. true.
The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.
The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.
<em>Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area. He noticed that the level of the water went down, and then some droplets appeared on the sides of the bag. which part of the water cycle caused water droplets to form on the side of the plastic bag? </em>
<em>(a) condensation (b) evaporation (c) precipitation runoff</em>
The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.
<h3>What is condensation?</h3>
It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.
Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.
Both processes play a major role in the water cycle of the ecosystem.

A is true because they do have a true nucleus or membrane-bound organelles .
It is speeding up because more distance is covered every second.
Explanation:
The car can be described to be speeding up because more distance is covered every second.
From what we understand about velocity and acceleration, the car is accelerating through the ramp.
It's velocity is increasing with every second it covers.
This will invariable reduce the time between each distance covered.
Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds.
This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.

The second stage of prenatal development begins at about two weeks after conception. at this point, the growing bundle of cells is called an embryo.
