Answer:
chloroplasts
Explanation:
cuz chlorophyll: green pigment found in chloroplasts that absorbs light energy required for photosynthesis.
It is essential for the mesophyll cells to receive a constant supply of glucose from the phloem in order to function properly.
What are mesophyll cells?
Mesophyll cells are a type of plant cell that are found in the mesophyll tissue of leaves. The mesophyll tissue is the layer of cells that is located between the upper and lower epidermis (surface layers) of the leaf, and it is responsible for photosynthesis, the process by which plants convert light energy into chemical energy.
Mesophyll cells are specialized for photosynthesis and energy production, and contain large numbers of chloroplasts, the organelles responsible for capturing light energy and converting it into chemical energy through the process of photosynthesis. The mesophyll cells also contain large numbers of mitochondria, the organelles responsible for producing ATP, the cell's main energy currency, through the process of cellular respiration. The mesophyll cells therefore play a vital role in providing energy for the plant, as well as for synthesizing other cellular products, such as hormones and enzymes.
Mesophyll cells are typically divided into two types: palisade mesophyll cells, which are elongated and located near the upper surface of the leaf, and spongy mesophyll cells, which are irregularly shaped and located near the lower surface of the leaf. The palisade mesophyll cells are responsible for absorbing light energy and conducting photosynthesis, while the spongy mesophyll cells provide a large surface area for gas exchange and help to regulate the temperature of the leaf.

Which is a best practice to help conserve the natural environment?
Apply water daily, whether it has rained or not.
Capture methane gas emissions from manure and use it as natural gas.
Dispose of manure in landfills.
Do as much tilling as possible.
Answer:
Capture methane gas emissions from manure and use it as natural gas.
Explanation:
Capturing methane gas emissions from manure and using it as natural gas is a best practice to help conserve the natural environment. Hence, option B is correct.
What is natural gas?Although ethane, propane, butane, and pentane are present in trace amounts, methane makes up the majority of natural gas. Four hydrogen atoms and one carbon atom make up the methane molecule. In homes across the United States and much of the rest of the world, natural gas has slowly risen to the top of the energy usage list. Compared to more conventional fossil fuels like coal and other hydrocarbons like crude oil, it is more efficient.
Natural gas is used in the business sector to heat buildings and water, run refrigeration and cooling systems, cook, dry clothing, and provide outdoor lighting. Natural gas is sometimes used as a fuel in combined heat and power systems by some commercial consumers.

Which of the following is not true of energy in a cell?
The cell must have energy to maintain homeostasis.
O Energy can be created by the cell.
O The cell uses mostly chemical energy.
O Energy can be converted by the cell.
Answer:
I think is the top one A hope this helps
Cells have a different function it can convert chemical energy to another form of energy to maintain homeostasis, and cells cannot create energy only change the form of energy, hence option b is correct.
What is the energy of the cell?Every cell must continue to check its levels of energy and adjust ATP production rates in line with metabolic demand in order to keep homeostasis.
The ability of cells to sense, and convert nutrients into chemical energy is essential for the continuous fulfillment of this energy demand.
To drive metabolic reactions that would not happen automatically, to transfer necessary substances across membranes, and to do mechanical work, such as moving muscles, cells need chemical energy.
Therefore cells use energy to maintain homeostasis and can change one form of energy into another but can not create energy, hence option b is correct.

1. do you feel the ends of the ruler pushing against your hands?
2. what will happen to the ruler as you release it?
3. what was stored as you bent the ruler using your left hand?
4. what will happen to the ruler as you take away your left hand quickly?
Answer:
Due to stored energy, the ruler moves in forward direction.
Explanation:
When we bent the ruler from its original position, energy is stored in the ruler so when we remove the hands from the ruler so it moves in the forward direction. When the ruler reaches to its original position so due to more stored energy, it moves more forward than its original position and vibrate on its mean position and finally remain at rest after sometime.

If a dormant volcano starts to release gases and small earthquakes are recorded, what could this mean?
Answer: It means that its showing some volcanic activity that could lead into an eruption.
Explanation: Dormant volcanoes can show activity/signs that is could erupt. Gases, small earthquakes, loud explosions are signs of an eruption is going to occur. If a dormant volcano hasn't showed any activity for 2,000 years, its considered to be dead or extinct.
It indicates that there is some volcanic activity, which could lead to an eruption.
What is dormant volcano?Dormant volcanoes are those that have not erupted in a long time but are expected to do so in the future. Mount Kilimanjaro in Tanzania, Africa, and Mount Fuji in Japan are examples of dormant volcanoes.
Volcanoes become dormant when magma from the Earth's mantle can no longer reach them. Mount Rainier and Mount Fuji are examples of dormant volcanoes that are "sleeping" but may awaken in the future.
Dormant volcanoes can exhibit activity/signs that they are about to erupt. Gases, small earthquakes, and loud explosions are all indicators that an eruption is about to occur.
If a dormant volcano hasn't erupted in 2,000 years, it's considered dead or extinct.
Thus, this way, it indicates that it could lead to eruption.

Do you believe your house would be prepared in the event of a tsunami? Why or why not?
Answer:
Yes because we don’t live by an ocean
Explanation:
Answer:
Just say no. If there is a tsunami, the average modern day house would be flooded and sustain significant structural damage. It would not be able to withstand the crushing forces of the water unless it is specially built. Assuming that you don't live in an area where tsunamis are likely, your house was not built that way.

Answer:
b. Net production is always less than gross production.
Explanation:
The main production i.e. done in ecology would do the production in the organic compounds with the help of photosynthesis. The gross production is the value i.e. generation of organic compounds by producers while the net production is the value of organic compounds i.e stored by producers. It should be lower than the gross production as the plants are not able to store large number of organic compounds than they generated

What is Metabolism? In a simple answer.
Answer:
Metabolism is the process by which your body converts what you eat and drink into energy.
The alterations in an organism's or a cell's chemistry. The term metabolism broadly refers to the chemical processes that take place in an organism's cells to support life.
What is Metabolism?The word "metabolism" in a cell may be defined as all the chemical processes that take place within the cell to carry out all cellular tasks e.g., growth, development, and reproduction.
Anabolic processes, which often need an input of energy held in the chemical bonds of complex molecules, are distinguished from catabolic events, which typically entail the release of energy and the breakdown of bigger molecules into simpler ones.
These modifications generate the ingredients and energy that cells and organisms require to develop, procreate, and maintain health.
Therefore, metabolism broadly refers to the chemical processes that take place in an organism's cells to support life.
