Answer:
The expansion of water upon freezing is vital to life on Earth. It is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. ... Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.
Explanation:
Answer:
When water molecules freeze, they form together and make a circle like structure.

Plz help!! We cannot survive without plants, while they would be fine without us. Explain.
Answer:
We cannot survive without plants because they give us oxygen and food. Plants would be fine without us because the earth gives them everything they need. The sun provides energy; rain, bodies of water, and groundwater provide water; the atmosphere provides nitrogen and carbon dioxide--all of these factors are required for photosynthesis to occur. This is how plants make glucose to feed themselves. Additionally, plants reproduce by several means, whether by pollination or wind spreading seeds to the ground.
Explanation:
Humans cannot survive without plants, while they would be fine without humans because plants produce oxygen.
Photosynthesis:
It is the process in the plant that produces glucose using the Carbon dioxide and water in the presence of sunlight.
During the process plants release Oxygen as byproduct which is used by all animals in the earth.Photosynthetic plants are the only source of Oxygen in the Earth.Plants are the primary producers in the food chain. Hence, consumers will not able to get the food.Humans do not do anything that is compulsive need of plants.
Therefore, humans cannot survive without plants, while they would be fine without humans.

Earth's second atmosphere (atmosphere III) was a thick atmosphere of primarily water vapor and carbon dioxide,
What effects did this have on Earth?
A. Heat energy was retained and water vapor condensed
B. Ultraviolet light split water vapor into hydrogen and oxygen.
C. Increased oxygen allowed reptiles to thrive.
D. Helium and hydrogen gases escaped earth's gravity
This had the same effect on Earth as it did on Mars. Heat energy was conserved, and water vapor was condensed.
What was the second atmosphere of Earth like?The second atmosphere, which remained on the planet, was formed by volcanic outgassing and comet ices. This atmosphere had almost no oxygen, but plenty of water vapor, carbon dioxide, nitrogen, and methane.When Earth's crust began to cool 2.5 billion years ago, there was less water vapor in the sky, and more water condensed into liquid, resulting in the formation of Earth's second atmosphere.The second atmosphere was formed by volcanic outgassing and comet ices, and it was the first to survive on Earth.A secondary atmosphere is a planet's atmosphere that did not form through accretion during the formation of the planet's star. Instead, a secondary atmosphere forms as a result of internal volcanic activity or the accumulation of material from comet impacts.To learn more about Earth's second atmosphere refer to:

Name the two major types of cell transport
There are two major types of cell transport: passive transport and active transport. Passive transport requires no energy. It occurs when substances move from areas of higher to lower concentration. Types of passive transport include simple diffusion, osmosis, and facilitated diffusion.
What’s the answer to this??
what molecule is this???
Answer:
NUCLEOTIDE
Explanation:
Nitrogenous base molecule is joined to sugar molecule by a glycosidic bond and forms a structure called nucleoside.The nucleoside combines with a phosphate group by an ester bond to form a nucleotide.A unit formed by the attachment of a base of 1' position of sugar is known as nucleoside when nucleoside is linked to phosphoric acid at 5' position of sugar moiety we get a nucleotide.If many trees are removed from a forest by

How does cellular respiration work in the human body?
Answer: Cellular respiration is a process in which your body cells use the oxygen you breathe to get energy from the food you eat.
Explanation: During cellular respiration the cell uses oxygen to break down sugar. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released. Carbon dioxide is a byproduct of aerobic respiration in humans.

Which are included in the inflammatory response? Select three options.
pain
swelling
antibodies
mucus
rednes
Answer:
the answer is redness, pain and swelling
Explanation:
The primary indicators of inflammation include discomfort, heat, redness, edema, and functional loss.
What are the main symptoms of inflammatory response?Redness (Latin rubor), heat (Latin calor), swelling (Latin tumor), and pain are the four primary indicators of inflammation (dolor). Small blood vessels in the injured area enlarge, resulting in redness.
Inflammatory cells and cytokines are the initial responders that your immune system dispatches (substances that stimulate more inflammatory cells).
Due to an allergic reaction, several of these symptoms are visible here. Heat, discomfort, redness, swelling, and loss of function are the five primary symptoms (Latin calor, dolor, rubor, tumor, and functio laesa).
Therefore, redness, pain, and swelling are included in the inflammatory response.
