Answer:
to retain moisture and hold the soil in place.
Explanation:
this technology of putting dead plants on the soil under the plants and the area nearing the plants is called mulching.it is helpful in reducing the rate of evaporation and also reduces soil erosion.
Conservation plowing is achieved to minimise soil erosion. Thus, option C is correct.
What is soil erosion?Soil erosion is the deterioration of the topmost layer of soil. The top fertile layer of the soil withers leaving the soil infertile.
It is a gradual naturally occurring phenomenon but can be accelerated with human interventions.
There are many factors responsible for soil erosion:
• Deforestation
• Excessive grazing
• Mining
• Construction work
• Drought and floods
Soil erosion negatively affects the crop yield and also clogs the water bodies. This is therefore harmful for the aquatic species. Dry and barren soil is more prone to floods.
Soil erosion should be minimized as it produces a negative impact on the ecosystem.
Soil erosion can be prevented by planting more number of trees. The roots of the trees help in holding the soil in its place.
Therefore, soil erosion should be checked to preserve the soil fertility.

What characteristics make white dwarf stars different from main sequence stars?
Answer:
Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs. White dwarfs no longer burn fusion at their center, but they still radiate heat.

A student uses a telescope to view stars at night. The student notices some of the stars are different colors. The color of a star is determined MOST by its
Select one:
a. size.
b. distance from Earth.
c. mass.
d. temperature.
The color of a star is determined most by its mass. Thus, option C is correct.
On which factor brightness of the star depends?The brighter the star is, the closer it will be from the Earth. Hence, the brightness of a star depends upon the distance between the star and the Earth. The color of a star tells you how cool or hot it is. Blue colored stars are cool while red colored stars are hot (like sun).
A star is a celestial object that produces light and heat through nuclear fusion reactions in its core. Stars are made up of hot, dense gas and have their own gravity, which helps them maintain their shape. They are classified based on their temperature, size, and luminosity.
Most stars are part of a galaxy and are found in clusters called star systems. The sun is a star and is the closest star to Earth. Stars play a crucial role in the evolution of the universe and are essential for the formation and survival of planets, including Earth.
Therefore, The color of a star is determined most by its mass. Thus, option C is correct.

What new compounds are formed during cellular respiration?
Oxygen & Glucose
Carbon Dioxide & Water & ATP
Water & Oxygen & ATP
Glucose & Carbon Dioxide
Answer:
I think the answer is Carbon Dioxide & Water & ATP.
New compounds are formed during cellular respiration are carbon dioxide,water, and ATP. Thus, option B is correct.
What is cellular respiration?
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP ( Adenosine triphosphate) that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is in cellular respiration, glucose and oxygen react to form ATP ( Adenosine triphosphate)
Adenosine triphosphate is an organic compound which gives energy to living organisms to drive many operations in living cells. such as muscle contraction, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Respiration is a phenomenon in which metabolic process is take place in the living organisms. It is biochemical process which takes place in the cell of organisms. In respiration energy (ATP- Adenosine triphosphate) is developed by splitting of glucose which will further used by cell to perform various function. Single-celled organisms always dominant over the multicellular organisms.
Therefore, New compounds are formed during cellular respiration are carbon dioxide,water, and ATP. Thus, option B is correct.

When the sun impacts weather, an interaction with the __________ takes place.
atmosphere
biosphere
geosphere
hydrosphere
Answer:
Hydrosphere
Explanation:
When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.
Weather is the atmospheric condition of a place over a short period of time.
The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.
This water in the atmosphere is forms rainfall, one of the elements of weather.
The sun causes an impact on weather by causing evaporation of water into the atmosphere.
This interaction takes place in the hydrosphere.
How does energy change from one form to another?
Answer:
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another.
Explanation:
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home's air to raise its temperature.
