The correct answer is deforestation.
Permanent clearing of forest by various methods is called deforestation. The cleared land is used for the various purposes such as planting crops, making roads, buildings. The destruction of forest trees on mass scale is carried out in various ways such as burning of trees and cutting of trees making the land complete barren. After wards barren land is used as per the need of native people.
Answer:
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.
The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
Answer:
The correct answer would be C. Involuntary responses are part of the autonomic system.
The autonomic nervous system (ANS) is sub-division of the peripheral nervous system (PNS) mainly associated with involuntary responses.
It regulates the psychological actions such as heart rate, respiratory rates, digestion, urination, sexual arousal, pupillary responses, thermoregulation, fight and flight responses et cetera.

B. They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.
C. They can be given DNA to allow them to resist harsh conditions.
D. They cannot be modified to be better than organic crops.
The correct option for the modification done that needs to be sprayed with pesticides is option (b) They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.
Here, we deal with the concept of genetically engineered crops, also called "genetically modified organisms" i.e., GMOs. GMOs approach the specific genes from bacteria of other organisms that produce the required toxins that are harmful only to pests that are inserted into the DNA of crops.
GMOs are examined by crops like Bt cotton or Bt corn. They are genetically modified genes from the bacterium Bacillus thuringiensis (Bt), which are produced by the toxic proteins of certain insects. The use of genetically modified organisms is a complex issue related to the potential health effects, environmental impact, regulatory oversight, and many more.
To learn more about the 'pesticides harmful for crops' are
b. epiglottis
c. bronchiole
d. laryngopharynx
Answer:
The correct answer is option c. "bronchiole".
Explanation:
The passage of airway within the lungs is known as bronchus. However, air exchange does not happen in the bronchus, it happens in small air sacs named alveoli. The smaller versions of the bronchus are known as the bronchiole, which branches further until it becomes the alveoli, the structure at which air exchange takes place.
B. Wood can rot.
C. Wood does not rust.
D. Wood is softer than coal.
