Plant cells can better tolerate exposure to hypotonic solutions than can animal cells. Which one of the following helps to best

explain why plant cells can better tolerate hypotonic solutions? a. The hot sun on plant cells causes any extra water to evaporate. b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake. c. Chloroplasts consume the extra water in photosynthesis, decreasing the swelling. d. The veins in plants drain away the extra water from the plant cells. e. Stomata in plant cell leaves quickly drain excess water from the cells.

Answer:

b. The rigid cell walls limit how far plant cells can expand and exert a back pressure to limit further water uptake.

Explanation:

Plant cells have a rigid cell wall made of cellulose. Animal cells lack a cell wall.  

When the plant cells are placed in a hypotonic solution, water enters into the cells and the cells expand. However, after a certain limit, the cell wall exerts wall pressure on the contents of the cell and does not allow it to take more water in. The wall pressure from the cell wall of plant cells protects them against bursting when placed in a hypotonic solution.

Animal cells burst out due to intake of water by osmosis when placed in a hypotonic solution. They do not have a cell wall to protect them from bursting.

Select all the correct answers.<br> Which two statements are true for the leading strand in DNA?
Ghella [55]

Question: Which two statements are true for the leading strand in DNA?

It is synthesized toward the replication fork.

It is synthesized in the 3′ to 5′ direction.

It is synthesized away from the replication fork.

It is synthesized in the 5′ to 3′ direction.

Answer:

The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"

Explanation:

Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.

What emerging technologies will make chemical energy safer, more usable, more efficient, and cleaner?
storchak [24]

Zipper fracking is a new technology that produces more oil and more gas, safely and effectively, all from rock formations. Well drilling is another way, you get clean, natural gas by drilling into wells that connect into the ground. All that being said, we could also get chemical energy to be more safer, more usable, more efficient, and cleaner, if people were not careless with their work.

Explain what is ecological conservation and conservation of the environment. What can you do to conserve the environment? Why do
den301095 [7]

Answer:

Conservation ecology is the branch of ecology and evolutionary biology that deals with the preservation and management of biodiversity and natural resources. Its goal is to find ways to conserve species, habitats, landscapes, and ecosystems as quickly, as efficiently, and as economically as possible.

-These are some examples of how we can conserve the environment:

Recycle your rubbish and participate in or help organize recycling campaigns.

Avoid littering and participate in or help organize litter clean-ups (here you can link to a website for volunteering or starting your own beach clean-up).

Use less plastic by, for example, carrying a reusable water bottle, saying no to disposable straws and cutlery, avoiding plastic toys, and bringing your own shopping bags (for further ideas on a plastic-free life take a look here).

Swap toys, movies, and books instead of buying new ones.

Donate, recycle, and repair electronic devices (see how here).

Use less water when brushing teeth, taking a shower, or washing the dishes.

Use less electricity by turning off lights and electronic devices when not in use, using energy-saving light bulbs, and hanging clothes to dry.

Use public transport, share a journey with friends (e.g., car-sharing), cycle, or walk when possible.

Use less paper by not printing unnecessary things and reading e-books.

Turn down the air conditioning when it is hot and use fans if you are still hot-they use much less power.

Turn down the heat when it is cold and use sweaters, blankets, and socks to keep warm.

Do not waste food and try to buy food that is grown locally and in season.

Hope this helps:)
