Crops are protected from disease-causing fungi by use of fungicides or by the use of genetically engineered fungi-resistant crop
Mkey [24]

Correct answer: C). Fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi.  

Fungicide is a chemical substance that is known to cause toxicity in fungi in order to kill them. Its use can help to reduce the number of fungal infection that causes great loss to plants and its productivity.

In genetic engineering, the DNA of plants is altered in such a way that it produces a toxic protein, which will kill the fungi when it tries to infect them or slow down the growth of the plant.

I need help please I don’t understand this
aleksley [76]

Answer:

2. It is converted into heat and energy.

Explanation:

So every time an animal eats grass, or another animal it receives 10% of the energy that the previous animal/plant had. If a rabbit ate a carrot, 10 percent of the energy the carrot had in it, will go into the rabbit. the question is asking where the 90% energy from the eaten carrot went.

Answer Explanation:

Most of the energy that isn't stored in the animal/plant is lost as heat or is used up by the body as it digests the animal/plant that was eaten. This is because the animals who consume any of the plants/animals receiving the 10% energy take energy to eat the plant/animal. this takes up the other 90%

I hope this helps :))
