Answer:Ground
Explanation:The roots help soak up moisture fromthe ground and can also store extra food made from photosynthesis
Photosynthesis occurs and extra food is stored in ground plant tissues in the form of sugars.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Sixth-grade students conduct a laboratory experiment investigating the flow of thermal energy. They place a sealed plastic bag filled with water at 60°C into a beaker filled with an equal amount of water at 80°C. They then put the beaker with the plastic bag in an insulated container.
Based on the flow pattern of thermal energy, what can students predict will most likely happen in about an hour?
A. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in the beaker will be 60°C and the temperature of the water in the plastic bag will be 80°C.
B. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in the plastic bag will be 80°C and temperature of the water in the beaker will be 60°C.
C. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in both the plastic bag and the beaker will be 70°C.
D. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in both the beaker and the plastic bag will be 70°C.

Is a change in matter that produces one or more substances
Chemical change
Physical change
Chemical reaction
Answer:
Chemical change
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
its not physical change: What is a physical change? A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
its not chemical reaction: A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products

If two oceanic plates move towards each other at a convergent boundary, then_____ may occur.
earthquakes
faults
ocean formation
mountains
volcanoes
island chains
seafloor spreading
pick two events
Answer:
I think the answer is Volcanoes.
Explanation:
If the two plates that meet at a convergent plate boundary both are of oceanic crust, the older, denser plate will subduct beneath the less dense plate. The older plate subducts into a trench, resulting in earthquakes. Melting of mantle material creates volcanoes at the subduction zone.
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.

Why does Mercury have almost no atmosphere?
Mercury spins on its axis too fast to have an atmosphere.
Radiation from the Sun blows the atmospheric particles off into space.
Mercury's gravity is too weak to hold an atmosphere.
Mercury orbits the Sun at such high speed that the atmosphere is blown away.
Answer:
There are two main reasons. First, Mercury is small and doesn't have much gravity so it's hard to hold onto an atmosphere. Second, Mercury is close to the Sun so any atmosphere gets blasted away by stuff being blown off the Sun.
Explanation:
Because Mercury has no atmosphere, it can't hold onto its heat very well. The night side of Mercury gets very cold, which brings down the average temperature of the planet and makes it only the second hottest planet in the Solar System after Venus.

Answer:
The amount of water vapor in a given volume of air is humidity.The amount of water vapor in the air at any one time depends on temperature . Warmer air holds more water than cooler air. Clouds form when humidity is low and thetemperature is high . Relative humidity is defined as the amount of water vapor in the air divided by the amount that would have to be present in the same air to form a cloud or condense on a surface. Dew is related to the humidity of the previous day. The air temperature at which water vapor in the air condenses onto cool surfaces is the dew point.

Why do chemical properties change?
Answer:
Chemical properties can change due to a variety of things. If you were to talk about Weathering, the chemical properties change when there is acid rain, water, CO2, and O2. Chemical Properties change when the chemical properties of an object change too.
