Answer;
Kingdom Eubacteria
A unicellular kingdom that does not have a nucleus would belong in the kingdom Eubacteria.
Explanation;
Kingdom Eubacteria is the kingdom of prokaryotic, single-celled organisms that lack a membrane-enclosed nucleus and can be classified by shape.
Prokaryotes are organisms that lack nucleus and other membrane bound organelles, such as mitochondria. Unicellular means that the organism is made of one cell.
Answer:
Option 4: Mucosa, Submucosa, Serosa, Muscularis
Explanation:
The correct sequence of the wall in the alimentary canal from deep to superficial is Option 4: Mucosa, Submucosa, Serosa, Muscularis. This order is based on the layers of the wall that make up the alimentary canal. The mucosa is the innermost layer and is made up of epithelial cells that are responsible for absorption and secretion. The submucosa is beneath the mucosa and contains connective tissue, blood vessels, and nerves. The serosa is the outermost layer and is made up of connective tissue, which helps to protect and support the alimentary canal. The muscularis is the layer beneath the serosa and consists of smooth muscle that is responsible for propulsion and movement of food.
Answer:
frictional
Explanation:
This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.
Because there is a limited frictional force (a force exerted by an object when an object moves across it) between
Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
b. economic consequences
c. development hindrances
d. all of the above
Answer: d. all of the above
Fossil fuels such as coal, oil and gas are beneficial sources of energy used by the human society. Fossil fuels are non- renewable resources, which are produced after millions of years of geological and biological activity taking place inside the earth crust. Human society is mainly dependent upon the fossil fuels to maintain it's energy needs.
There are some negative consequences associated with fossil fuels:
Environmental consequences: Fossil fuels are used for generation of energy in the power plants and by the automobiles. These sources releases partially and completely combusted products which includes the poisonous gases causing air and water pollution.
Economic consequences: Fossil fuel use is related with economic crisis because fossil fuels are non- renewable resources, which cannot be replenished once used. They are expensive and many commercial energy generation processes are dependent on them such as electricity, transportation and others.
Development hindrances: Large dependence on fossil fuels creating an hindrance on development process. As, there are very few findings which are resulted which could replace the fossil fuels, these finding can be beneficial for the environmental and economic point of view.
