Why are fungi classified together?
They get their food the same way
They have a similar behavior
They grow in the same areas
They look alike
Answer:
A, they get their food in the same way.
Explanation:
Some fungi can be toxic or poisonous.
Example: mushrooms. Mushrooms typically are found in forests and meadows/plains.
Some fungi are glowing, brown, and in many forms/shapes.
In conclusion, fungi all get nutrient from the dirt they grew in, forests can be moist which gives fungi excellent places to form, usually around trees, because they can absorb plenty of nutrients from the dirt.

This is the type of wave that travels in one direction but the energy travels in the opposite direction
Answer:
Transverse wave
Explanation:
A wave is defined as a disturbance along a medium which transfers energy from one point to another.
A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.
In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.
How many molecules are in 10 moles of H2
The number of molecules in one mole of hydrogen gas is 6.02 × 10²³ . The number of molecules in 10 moles of hydrogen gas is then 6.022 ×10²⁴.
What is one mole?Any substance that contains 6.022 × 10²³ number of atoms is called ne mole of that substance. This number is called Avogadro number. Hence, one mole of every elements contains Avogadro number of atoms.
Hydrogen is the first element in periodic table. It is an alkali metal. The number of molecules in one mole of H₂ is equal to Avogadro number. Mass of a molecule with one mole of amount is called its molecular mass.
Number of molecules of H₂ in one mole = 6.02 × 10²³
Then number of molecules in 10 moles is Avogadro number times the number of moles.
= 10 × 6.022 × 10²³ = 6.022 ×10²⁴ molecules
Therefore, 10 moles of H₂ contains 6.022 ×10²⁴molecules..

2 eggs cook in a frying pan, which is sitting over a gas burner. Is thermal energy being transferred by radiation in this image? Why or why not?
Sample Response: No, thermal energy is not being transferred by radiation in this image. The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation. Radiation transfers thermal energy by electromagnetic waves, not by direct contact.
Explanation:
No, thermal energy is not being transferred by radiation in this image.
The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame.
Thermal energy is being transferred by conduction.
Radiation transfers thermal energy by electromagnetic waves.
Radiation does not transfer thermal energy by direct contact.
Thermal energy is the heat energy that is produced with an increase in temperature. No, thermal energy is not transferred by radiation when eggs are cooked.
What is radiation?Radiation is the process of thermal energy transfer that emits heat in all directions and does not require an intervening medium to travel.
Thermal energy is not transferred by radiation in the image as the eggs are in contact with the pan and the pan is in direct contact with a flame that radiates the heat by conduction.
Therefore, heat transfers by conduction and not by radiation.

Which of the following best describes the Earth's movement around the sun?
A)The Earth is closer to the sun in Summer than in Winter.
B)The Earth moves in a circular pattern around the Moon
C)The Earth's axis moves back and forth, resulting in different seasons
D)The Earth moves in an elliptical orbit around the sun
Answer:
D)The Earth moves in an elliptical orbit around the sun
The statement earth moves in an elliptical orbit around the sun best describes the movement of earth around the sun.
What is earth?Earth is the third planet of the solar system and the only astronomical object known to support life.
What is an elliptical orbit?When an object moves around another object in an oval shaped path, it is known to be revolving in an elliptical orbit.The orbit is elliptical because of Newton's law of gravity.The planets in the solar system orbit the sun in elliptical orbits. Many satellites orbit the Earth in elliptical orbits as does the moon.The movement of the earth around the sun in a fixed path or orbit is called Revolution. The axis of the earth which is an imaginary line, makes an angle of 66½° with its orbital plane.

How many molecules are contained in 125 grams of water, H20?
Answer:18.015 g
Explanation:
Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g

Si en un laboratorio hay 300 moles de plomo y 300 moles de plata en cual de los dos casos la masa en mayor?
Answer:
Esto significa que la masa en las moles de plomo es mayor que en las de plata.
Explanation:
Las moles de los átomos representan la cantidad de átomos presentes. Para saber la masa de los átomos debemos convertir las moles a gramos usando el peso molecular de cada uno de los átomos (207.2g/mol para el plomo y 107.82g/mol para la plata).
La masa de plomo en 300 moles es:
300 moles * (207.2g / mol) = 62160g de plomo
Y la masa de plata es:
300 moles * (107.82g / mol) = 32346g de plata
Esto significa que la masa en las moles de plomo es mayor que en las de plataAccording to the Heisenberg uncertainty principle, it is impossible to know both the __ and __ of an electron simultaneously.

A substance has a density of 5.4 g/cm^3. Another substance has a density of 5.4 kg/m^3. Which substance has the greater density
Answer:
The density of substance A is more.
Explanation:
Given that,
The density of a substance is 5.4 g/cm³.
The density of another substance is 5.4 kg/m³.
We need to find a substance that has a greater density.
First, we make the units the same.
1 kg = 1000 g
1 m = 100 cm
5.4 kg/m³ = 0.0054 g/cm³
Now, if we compare 5.4 g/cm³ and 0.0054 g/cm³, we find that the density of substance A is more.
