Monoculture is the raising of crops and livestock to make an entire breed or population have individually identical genes. Monoc

ulture is very productive and efficient because it can yield a huge supply of a single crop, such as corn or soybeans. Monoculture has several negatives to its use. If a disease is contracted by one individual in a population of genetically-identical plants, then the whole population could be wiped out. Other negatives include all BUT ONE of the following points. That is A) increased herbicide and pesticide use. B) monoculture quickly depletes the soil of nutrients. C) a decrease the genetic variation of certain gene pools. D) a decrease in the cost to farmers who rely on monocultures.

Answer:

The correct answer is option D, a decrease in the cost to farmers who rely on mono cultures.

Explanation:

All the options except D, are the disadvantages of monoculture in the following ways  

A) increased herbicide and pesticide use – Due to monoculture the nutrients in the soil gets depleted and thus more and more fertilizers are used which attracts more and more pests and to kill the pests more and more herbicides and pesticides are used

B) monoculture quickly depletes the soil of nutrients. – This is so because same crop uses same nutrient and continuous monoculture do not give land sufficient time to replenish its lost nutrients.

C) a decrease the genetic variation of certain gene pools – due to monoculture , probability of cross fertilization becomes nill

D) a decrease in the cost to farmers who rely on monocultures-there is no decrease in cost to farmers as input of fertilizer, herbicides and pesticides increases which enhances the cost.

Important advantages to raised-bed gardens are that they
Illusion [34]

A raised-bed garden is a type of gardening method in which the vegetables and other small plants are grown in garden boxes kept elevated above the ground. These garden boxes are kept separated from each other.

The advantages of having a raised-bed garden are:

1. The movement of harmful pest from crop to another is hindered.

2. It prevent the compaction of the soil.

3. It stops the propagation and growth of weeds from one box to another.

4. It provides better drainage of water from the soil.

5. The walls of the garden box prevent the erosion of the soil.

6. The garden boxes conserve space.

Hence the answer will be B. conserve water and space for growing and limit compaction of the soil.

serg [7]

Answer:

S1 and S3

Explanation:

The spine is composed of 33 vertebrae and has 31 pairs of nerves that are distributed throughout the body in an organized manner. Each nerve that leaves the spine is responsible for imparting sensitivity and strength to a particular area of the body, so whenever there is a compression or cut of a nerve, a particular area of the body is compromised.

When a person has a feeling of numbness in the foot, as shown in the above question, it is more likely that there is a change in the spine, specifically in the nerves S1 and S3. This is because nerve S1 is responsible for eversion of the foot, while nerve S3 is responsible for the intrinsic muscles of the foot.

Life sciences about gaseous exchange please help.​
dem82 [27]

Gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.

<h3>What is cellular respiration?</h3>

Cellular respiration is a series of chemical reactions by which aerobic organisms interchange oxygen and carbon dioxide with their surrounding environment.

During cellular respiration, oxygen is consumed to generate ATP and carbon dioxide is released.

In conclusion, gaseous exchange is fundamental in aerobic organisms because oxygen is required to carry out cellular respiration.

Exposure to radiation can best be reduced for the patient by
ICE Princess25 [194]
You can reduce the risks of radiation exposure by:

1. Eating foods that contain chlorophyll. Foods that contain this substance detoxify the blood, helping to remove all kinds of nasty toxins including radiation.

2. Ingest sea vegetables. Kelp, dulse, and agar contain natural iodine, which protects against radioactive iodine found in foods like dairy products.

3. Supplement with bee pollen. It can protect your body against x-ray induced radiation sickness.

4. Limit daily exposure to nonionizing radiation.
