Identify the state of matter: Takes the shape of the container that it's in,
particles are very far apart, particles have high thermal energy.

Answers

the answer is gas :)

The state of matter that is described is a gas; in a gas, the particles are not held together in a fixed arrangement like in a solid but are instead free to move and take on the shape of their container.

What is gas property?

The state of matter being described here is gas. In a gas, the particles are not held together in a fixed arrangement like in a solid but are instead free to move and take on the shape of their container. Gas particles are very far apart from one another compared to particles in solids and liquids, which allows them to easily flow and diffuse. Gases also have high thermal energy, meaning their particles are in constant motion and collisions between particles are frequent. This results in gases expanding to fill any available space and exerting pressure on the walls of their container.

Hence, the state of matter that is described is a gas, as in a gas the particles are not held together in a fixed arrangement like in a solid but are instead free to move and take on the shape of their container.

Place the following taxonomic ranks in order from most specific to least specific. A) Order; B) Phylum; C) Family

Answers

Here’s all of them: kingdom, phylum, classes, order, families, genus, and species

The taxonomy is a branch of biology which classifies the living things. It was given by Carolus Linnaeus. The taxonomic ranks in order from most specific to least specific is family, order and phylum.

What is Taxonomic Hierarchy?

The process of arranging different kinds of organisms into successive levels of the biological classification either in a decreasing or an increasing order from kingdom to species and vice versa is known as Taxonomic hierarchy.

Each level of the hierarchy is defined as the taxonomic category or rank. In this system of classification, Kingdom is always ranked the highest which is then followed by division, class, order, family, genus and species.

The correct order of Taxonomic Hierarchy is:

Kingdom - Phylum - Class - Order - Family - Genus - Species.

The species is the lowest level of the taxonomic Hierarchy. This can be further divided into sub-species.

Temperate grasslands have trees and shrubs
True or false

Answers

The answer is False.
Temperate grasslands do not have trees and shrubs.

Temperate grasslands have trees and shrubs. This statement is false.

What do temperate grasslands have?

Cold winters and mild, rainy summers are characteristics of temperate grasslands. Every year, grasses wither to their roots, and the soil and sod shield the roots and young buds from the winter cold or dry circumstances.

Because of the lack of rainfall, this biome may have a few trees along the streams, but not many.

The correct amount of rain and other factors aren't present in grassland ecosystems for trees to flourish, yet there is enough rain for grass to grow and cover the ground there. The length of the grass in grassland ecosystems can vary depending on the precise amount of rainfall.

Thus, Temperate grasslands do not have trees and shrubs.

Answer:

-rainfall is low

-occur in all climate zones

-contains grasses and woody plants

The grasslands occur in all climatic zones, contains grasses and Woody plants and rainfall is low. Therefore, option B, C and D are correct.

What do you mean by the grassland ?

The grassland biome is made up of broad, open grassy areas. They are kept healthy by animals that feed on them and frequent fires. There are two main types of grasslands: savannas and temperate grasslands.

Grasslands are grassy areas that are often flat, open, and continuous. In high latitudes, they are usually located between subtropical deserts and temperate forests.

Due to the environment, only grasses can thrive in grassland areas. Low precipitation rates are adequate for grasses but not for a forest of trees. Frequent fires also help to preserve grassland ecosystems. Grasses are ideal for recovering from a fire.

Thus, option B, C and D are correct.

Increase the temp I think

The concept Le Chatelier's principle is used here to determine the effect of change of concentration, pressure and temperature on the state of equilibrium.

What is Le Chatelier's principle?

According to Le Chatelier's principle, If a system in equilibrium is subjected to a change in concentration, pressure or temperature the equilibrium shifts in the direction that tends to reduce the effect of the change.

Here adding CaO increases the rate of forward reaction. If the concentration of any reacting species is increased, the equilibrium will shift in the forward direction.

The given reaction is exothermic in forward direction. So the increase of temperature shift the equilibrium to the backward direction and the decrease in temperature shift the equilibrium to the forward direction.

Here increasing pressure will shift the equilibrium to the forward direction accompanied by a decrease in the number of moles.

Answers

Answer:

Diurnal means active at night and Nocturnal means awake during the day and use the light to their advantage

Explanation:

*sigh*... where do I even began... it seems that the person above did you wrong. Nocturnal means active at night, and Diurnal means active during the day. This means that Diurnals, such as us humans, use light to our advantage. If you’ve already answered whatever you needed to answer, I’m sure you’ve realized that the answer above was absolutely wrong... IF YOU HAVENT, OR YOUR TEACHER HASNT GRADED SOMETHING, PLEASE GO FIX IT NOW!!!!

(Just in case you need clarification, I believe the exact definition of Nocturnal is as follows:
Done, occurring, or active AT NIGHT. The exact definition of diurnal, in this case (for animals), is: Active IN THE DAYTIME. The person above was either messing with you or did not look up their facts. Either way, I’m sorry about the inconvenience. I hope I was able to help in time to make a difference.)
