I need a short personal paragraph on clean neighborhood for work.
All of us live in a neighbourhood or surrounding. We must keep our surroundings neat and clean. This will help us to live a healthy life. Keeping our surroundings clean will only help in the betterment of society. Waste or garbage should not be thrown anywhere, but only in trash bins. Throwing garbage all over the place will dirty our surroundings, pollute the environment. Controlling the use of plastic bags will help to keep our surroundings clean. One should use recycled and eco-friendly products like paper or jute bags instead of others. Littering causes land, air and water pollution. Greener surroundings look beautiful and reduce pollution. Dirtying our surroundings will cause harm to us. So, keep the surroundings clean, live happy and healthy lives.
HOPE IT HELPS YOU .during which phase of the cell cycle does most cell growth occur
Cell growth occurs constantly throughout interphase. S phase is the time when all the cell's chromosomes are replicated so significant cell growth occurs here, but during both G1 and G2 cell growth occurs.
hope this helps
During the interphase of the cell cycle most cell growth takes place.
What is cell cycle?A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the maximum of its time in what is referred to as interphase, where it grows, reproduces its chromosomes, along with prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
The cell cycle's longest phase is interphase. This is the stage at which the cell undergoes and duplicates its DNA before entering mitosis.
Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.
Thus, the cell growth takes place in the interphase of the cell cycle, and the division takes place in the M-phase.

Which of the following is not a cycle of matter?
O Nitrogen Cycle
O Energy Cycle
O Water Cycle
O Carbon Cycle
Nutrient cycle is also known as the cycle of matter. Nitrogen, water and carbon all three are cycle of matter but energy cycle is not. Thus, correct option is B.
What is Nutrient Cycle?
Cycle of matter are also known as Biogeochemical cycles. These cycle include both biotic and abiotic factors. Cycle of matter are described into five types based on matter: a. water cycle, b. nitrogen cycle, c. phosphorus cycle, d. sulfur cycle, e. carbon cycle.
Matter constantly moves in the cycle involving change in the state. The matter cycles are essential as they recycle important nutrients required for the survival of living organisms.
In contrast to this, energy flows in the atmosphere. It is the interaction between the energy sources within Earth. The interaction between energy sources and Earth's atmosphere is very significant and a small change could lead to significant change in climate behavior of an area.
Therefore, the correct option is B. Energy cycle is not a cycle of matter.

What happens to the temperature of the water when it begins to melt?
Answer:
When you heat ice, its temperature rises, but as soon as the ice starts to melt, the temperature stays constant until all the ice has melted.
According to the graph, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.
What will happen if the ice melts?When the ice melts, the level of seawater would tend to be increased. This is because solid ice has tended to change its state to liquid. And now liquid may increase the density of the seawater which ultimately rises its level.
It is noted that when the temperature reaches that 0°C. For some instances of time, it will remain the same, but as time passes it tends to increase. The same principle is seen when the temperature reaches 100°C. So, it can not be said that the temperature remains at 0°C or 100°C until the changes in state.
Therefore, the temperature of the water continues to increase during the change of state. Thus, the correct option for this question is A.

Which best describes the role of chlorophyll in energy conversion?
Answer:
Explanation:
Chlorophyll absorbs light and converts it to chemical energy. ... During photosynthesis, plants absorb light energy from the sun and convert it into chemical energy in the form of glucose.
The role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.
What is Chlorophyll?Chlorophyll may be defined as the type of green-colored pigment which is present in all green plants, some algae, and cyanobacteria. It is present in the chloroplast of the plant and carries out the entire process of photosynthesis.
This green-colored pigment is generally made up of porphyrin rings with magnesium being the co-factor. A chain of carbon and hydrogen is also present. This is known as the Phytol tail. The function of chlorophyll in each photosynthetic organism remains the same throughout.
Therefore, the role of chlorophyll during the process of photosynthesis is that it effectively converts the captured radiant energy (light energy) from the sun to chemical energy.

Water would be considered an actual renewable resource and actual nonrenewable resource. Thus, option C is correct.
Why water is considered as actual renewable?Water would be considered an actual renewable. A renewable resource is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as wood, paper and leather.
Non renewable energy comes from sources that will run out or will not be replenished in our lifetimes-or even in many, many lifetimes. Non renewable energy sources are fossil fuels: coal, petroleum, and natural gas.
Potential renewable resource, potential nonrenewable resource, and actual renewable resource and actual nonrenewable resource. Water would be considered an actual renewable.
