Answer:

The correct answer will be option-D

Explanation:

Tonicity is a measure of the concentration of the solute particles inside to the outside a cell.  Tonicity is important to a cell as it determines the direction and movement of the water and solute by the process of osmosis.

The animal cells prefer an isotonic solution with the same amount of solute and water concentration as they lack a cell wall, due to which if water enters will cause lysis of the cell.

The plant cell prefers the hypotonic solution with low solute concentration due to which the cell can easily enter the cell and can be stored in vacuole if needed.

Thus, option-D is the correct answer.

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:)

Which of the following describes the ability of a single gene to have multiple phenotypic effects?
bija089 [108]

Answer:

A, pleiotropy.

Explanation:

Pleiotropy - genes that have multiple phenotypic effects. Remember that phenotype means a physical characteristic caused by a gene, such as eye color or fur patterns.

Incomplete dominance - when neither allele is dominant and they mix together in the phenotype. A popular example is a red flower crossing with a white flower and resulting in a pink flower.

Epistasis - when two genes contribute to the phenotype, but one gene completely masks another gene. An example would be labrador fur colors.

Multiple alleles - 3 or more alternative forms of a gene, but only 2 alleles can occupy an organism. An example is blood type.

Hope this helps!
