Answer:
When fossil fuels are bumed they release toxic gases into the air that cause pollution and increase global warming
Explanation:
Fossil fuels are fuels which were formed from the remains of dead plants and animals buried underground for millions of years ago, which anaerobic bacteria and the high pressure and heat underground transformed into the fuels as we know them today. Fossil fuels are mainly hydrocarbons and they include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.
The combustion of fossils fuels today provides the majority of the energy used by man worldwide. Energy from fossil fuels power our homes and industries, cars, trains aeroplanes, etc.
However, the combustion of fossil fuels impacts the environment negatively. Fossil fuels produce carbon dioxide as end-products when burnt which pollutes the airanspd is a major greenhouse gas contributing to global warming.
Combustion of fossil fuels releases acidic gases such as sulfur dioxide, nitrogen dioxide to the environment resulting in acid rains as well as many unpredictable and negative changes in the environment.
Answer:
Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens.
Nuptial flight: a flight of sexually mature social insects (as bees) in which mating takes place and which is usually a prelude to the forming of a new colony; especially : the mass flight and mating of winged sexual forms of ants after leaving the parent nest.
Cocoon: a silky case spun by the larvae of many insects for protection in the pupal stage.
Group B:
Not sure) a- Keep in cold places because when there are changes in weather, it could help the silkworm come out faster.
b-They live together in a large, well organized group and bees engage in complex activities that required works from other community members in the bee society.
c- i dont know this part sorry =(
d-The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature Bee larvae have been shown to be an excellent food source for rearing insects
Explanation:
1 Na = 23 g/mol
1 mole of Na atom contain an Avogadro Number of atoms .
23g of Na Na atom contain 6.02 * 10²³ atoms.
175 g of Na will contain: 175 * <span>6.02 * 10²³ / 23
</span>
≈ 4.580 * 10²⁴ atoms of Na.
