To figure out something based on observation or provided information is termed an inference. Information about the fossils is used by geologists to draw inferences about the organisms that existed long ago.
What are fossils?Fossils are the remains of once-alive organisms that are altered geologically. The dead remains of past lives had been preserved by the earth's crust. They are of interest to geologists and are used to determine the age of rocks
Any living creature – animal, plant, bacteria, and fungus – can be fossilized, but because fossilization is a process of destruction, not all fossilized organisms survive. Most fossilized organisms are consumed, rot or die out in the environment before they can become fossils.
Under normal conditions, only the outermost layers of the most difficult animals and plants fossilize. However, sometimes the conditions are right to fossilize entire soft-bodied organisms.

In what period did fish, mammals, reptiles, amphibians, and plants appear on earth?
Explanation:
In Cretaceous Period,fish mammals,reptiles,amphibians,and plants appeared on the earth.
The Devonian Period lasted 417 million to 354 million years. Ammonites, starfish, corals, crinoid stems, armored fish, sharks, early bony fish, and early amphibians were among the living things during the Devonian Period.
What is Devonian Period?The Devonian, a Paleozoic era, is also known as the Age of Fishes because it produced a diverse range of fish.
The most fearsome were the armored placoderms, a group that first appeared during the Silurian period and had powerful jaws lined with bladelike plates that acted as teeth.
Throughout the Devonian period, the Earth was hotter and drier than it is nowadays.
Warm and equatorial climates were widespread, as evidenced by the abundance of evaporite basins in the Northern Hemisphere, coal deposits in Arctic Canada and Spitsbergen, as well as pervasive desert circumstances and carbonate reefs.
Dunkleosteus terrelli was the largest species and most likely the largest fish in Devonian times. It could eat almost anything because it was one of the largest and most powerful fish ever.
Thus, the fish, mammals, reptiles, amphibians, and plants appeared on earth in Devonian Period.

Deer are eating Mr. Thompson’s rose bushes. He puts a new deer repellent on half of his rose bushes and then waters them. He uses the same amount of water on the other half of his rose bushes but does not put the repellent on them. What is the control group for his experiment?
Answer:
Explanation:
What he is trying to do is see if the repellant does any good. So the roses that do not get the repellent are the control group.
If they become 1/2 chewed up, and the others do not, the repellent works.

How are the functions of the small intestine and the large intestine different? A: The small intestine absorbs nutrients and wastes out of the digested food, while the large intestine produces a digestive juice to break down the food. B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste. C: The small intestine provides oxygen to the digested food before it goes to the rest of the body, while the large intestine absorbs nutrients and wastes from the food mixture. D: The small intestine pumps food and nutrients throughout the body, while the large intestine turns the digested food into a thin liquid mixture. PLS HELP
Answer:
B: The small intestine breaks down food into a thin mixture containing nutrients, while the large intestine absorbs water from the food mixture and turns it into solid waste.
Explanation:
Small intestine and large intestine are the important organs of digestive system in the human body. The small intestine functions by absorbing the nutrients of the simpler form of food. After absorbing the nutrients, the residue left is passed to the large intestine. The large intestine absorbs the water and further helps in eliminating the feces. It do not produces any enzyme to break the food unlike the small intestine. The process of digestion is completed by the small intestine.

Group of answer choices
oxygen

Answer:
Energy
Explanation:
Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.

Why is it important that the seedling’s true leaves grow quickly?HURRY IM BEING TIMED
to help disperse seeds to areas where they can grow
to shield the seedling from too much water or rain
to protect the seedling from receiving too much sunlight
to make food for the seedling’s continued growth
Answer:
The correct answer is - to make food for the seedling’s continued growth.
Explanation:
The true leaves that emerge from the seedlings are the leaves that are capable of performing photosynthesis and start generating food and energy. These support the plant for the rest of its life in terms of food and energy.
Seedlings grow from the soil, two leaves in beginning called cotyledons that are not the true leaves and not able to perform photosynthesis and generate their food for the seedling’s continued growth.
