If a hot liquid is poured into a cup, the cup will soon feel warm. How does the increase in temperature change the particles that make up the cup?
Answer:
Adding energy (heating) atoms and molecules increases their motion, resulting in an increase in temperature.
Removing energy (cooling) atoms and molecules decreases their motion, resulting in a decrease in temperature.
Energy can be added or removed from a substance through a process called conduction.
In conduction, faster-moving molecules contact slower-moving molecules and transfer energy to them.
During conduction the slower-moving molecules speed up and the faster-moving molecules slow down.
Temperature is a measure of the average kinetic energy of the atoms or molecules of a substance.
Heat is the transfer of energy from a substance at a higher temperature to a substance at a lower temperature.
Some materials are better conductors of heat than others.

Starting on bare rock what is the usual ecological succession of organisms
Complete question:
Starting on bare rock, what is the usual ecological succession of organisms?
a)shrubs--grasses--lichens--trees
b)lichens--shrubs--grasses--trees
c)grasses--shrubs--lichens--trees
d)liches--grasses--shrubs--trees
Answer:
d)liches--grasses--shrubs--trees
Explanation:
The succession is the colonization of an open area and includes all the changes the area suffers since then. It is a sequence of events that involves the establishment of different species through time.
There are two types of succession, primary and secondary, depending on the magnitude of the alteration.
Primary succession refers to an open space with no living organisms, such as a bare rock exposed due to a retreating glacier, a volcanic activity, or an intense fire. If previous species were inhabiting this area, after the event, nothing is left.
In those cases where there is an alteration or disturbance at a site that opens the area, it allows new species to grow. With time, new species arrive and manage to establish again. The order of the establishment depends on the strategies of each of the species to survive.
First, pioneer species arrive. These are the first inhabitants, mostly lichens or moses with the capability of surviving in such an environment. Only a few pioneers can establish in the open space. Pioneers modify the habitat. They make it more suitable for the establishment of later species, converting rock into fertile soil. As conditions get better, new species arrive like grasses. Grasses and pioneers keep modifying the soil, making it better with time. New species arrive, like small species, bushes and shrubs. Habitat modification keeps on going while new species establish (trees, pines, among other big species). They produce shadows, alter the temperature, and humidity, fertilizing the soil, competing for resources. Competition becomes more frequent between species. The first species are eventually eliminated by competition, but new species keep appearing and competing for resources. This sequence continues until the commuting reaches a climax, becoming stable and lasting for hundreds of years until another disturbance occurs.
Answer:
D. liches--grasses--shrubs--trees
Explanation:
primary ecological succession will be as: lichens inhabit bare rocks and breakdown the minerals rich material in the rock and die to produce organic material so that new species could be formed as grasses will grow which will become shrub and eventually the tree. Animals eat those grass, shrub or tree products.
In plants and animals, sexual reproduction causes variation
within a species. This variation is vital to their survival. How does
genetic variation affect a species' survival?
A. A species with variation is more easily found by predators.
B. A species that shows more variation will have a longer life cycle.
C. A species that has no variation might eventually become extinct.
D. A species without variation will overpopulate and produce new
species.

Which of the possible examples below would most likely lead to a change in the cell theory? A Scientists find life on Mars that is not made of cells. BScientists identify a cell organelle that practices the process of photosynthesis. C Scientists determine that an organism is living if it is made of twenty structurally-identical cells. D Scientists gather life from a volcano that is composed of cells which are very different from humans.
Answer: Probably B?
Explanation:
The possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.
What is the significance of the cell and its importance?Cell theory explains that life is made up of cells, but If scientists were to discover life on Mars that did not fit this definition, it would challenge the current understanding of the cell theory and the discovery of life on Mars that is not composed of cells would indicate that the cell theory is not universally applicable.
Hence, the possible examples below would most likely lead to a change in the cell theory: Scientists discover life on Mars that is not made of cells, i.e., option A, despite the fact that the cell theory states that all living organisms are made of cells.

In 2-3 sentences explain pollination.
Answer:
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. (I'm sorry this is about Pollution, it should be about Pollination, I misread it sorry,)
Pollination:
Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.
