Vacuoles are cell structures that are sometimes compared to warehouses. They have the ability to store things such as water and nutrients, and in some cases provide rigidity for the cell. Certain types of cells utilize vacuoles more than others. In what type of cell would you expect to find the largest vacuole?
A) A cactus cell
B) A human cell
C) A worm cell
D) A mushroom cell
Answers
Answer:
A) A cactus cell
Explanation:
Plant cells have much larger vacuoles than animal cells, so I believe the cactus cell would have the largest one.

5. Do you drink bottled water? Why or why not? What is its effect on the environment?
pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

A girl has her eyes shut and is standing inside a brightly lit room. What happens to her pupils when she opens her eyes? Why?
Answers
Answer:
When you open yours eyes in a brightly lighted area to a dark room (such as a cinema hall), you experience difficulty in seeing objects for a short while slowly, your vision is improved. This improvement is called dark adaptation. This change is due to (a) regeneration of the visual purple (or rhodopsin), the pigment of the rods, which was earlier broken down due to bright light, and (b) dilation of the pupil permitting more light to enter the eyes.
The pupil will constrict. Bright light will contract the muscles of the iris.
What is structure of an eye?An eye is a spherical structure responsible for vision.
An eye consists of three main layers:
Outer layer: It consists of cornea and sclera. Cornea extends into a membrane like structure called conjunctiva.Middle layer: This layer contains iris, ciliary body and choroid.Inner layer: Consists of retina where an inverted image of the object is formed. The optic nerve carries the visual information to brain.Two fluids namely aqueous humour and vitreous humour are present which maintain the shape of an eye.
The coloured part of an eye is called iris. It regulates the intensity of the light entering to the eye by controlling the diameter of a pupil (small aperture in the iris).
The lens of an eye is biconvex. It directs the light to the retina.
Therefore, eye is a crucial sensory organ.

Label the Big Dipper, Little Dipper, and indicate the Polaris.
Answers
The Polaris lies in a direct line with the Earth's rotational axis, which is "above" the North Pole (north celestial pole). Its stands almost motionless in the sky, and all the stars of the northern sky appear to rotate around it. The attached image is a clear indication.
How can we describe the Polaris location in the sky?The Polaris appears to remain stationary in the sky while all other stars appear to rotate around it. To locate Polaris in the sky, one must first find the Big Dipper, which is a well-known group of seven stars that resemble a ladle or dipper. If one follows the two stars at the end of the bowl of the Big Dipper, they will point directly to Polaris.
Once located, Polaris can be used as a guide to determine one's direction when navigating at night. Because it is very close to the celestial north pole, its position in the sky is directly above the Earth's geographic North Pole. This makes it a reliable reference point for navigation in the Northern Hemisphere.
