It’s painful because when they sing, a chemical is released called melting into the victim. That venom quickly triggers the receptors of pain, and thus causing the burning sensation. Another reason is because the stinger on a bee is barbed and when it sinks into the skin, it detaches from the bee and stays into the skin of the victim.
Answer:
Isomerization
Explanation:
In nature, when a carbohydrate has a formula, this formula can be share with different compounds (isomers) because they have the same number of atoms of the same elements, but the arrangement is different.
For example, the formula C6H12O6, is the same for glucose and for fructose, but in living things, when they process these two molecules, they do it with two different metabolic paths. With the specific use of enzymes, the body can separate one from another. In some cases, the mistakes can occur inside a cell process, leading a different metabolic path.
Hope this info is useful.
see plants are also living beings, they also need oxygen for respiration. There would be less carbon dioxide available for plants for photosynthesis. Atmosphere will be clean, less polluted, clean water. No fighting, peaceful, cool environment

Answer:
Option 3, 20 or 22
Explanation:
A newly discovered species of dung beetle has 2n = 16 chromosomes. It mates with a closely related beetle species that has 2n = 12 chromosomes. How many chromosomes would there be in an allotriploid beetle produced from this cross?
- 40 or 44
- 20 or 22
- 20 or 22
- 36 or 48
- 40 or 44
Solution
An allotriploid is a species which contains three sets of chromosomes of different species .Crossing can result in triploid offspring with diploid gamete of one species and regular haploid gamete of other offspring
Case I - Resulting offspring (3n) = Gamete I (2n) + Gamete II (n)
OR
Case II - Resulting offspring (3n) = Gamete II (2n) + Gamete I (n)
Case I

Case II

Hence, option 3 is correct
