Answer:
True
Explanation:
The bacterial cultivation refers to growing the bacterial species for exploitation or use. But the humans are not able to cultivate the majority of the bacterial species present which could be accounted for many reasons.
The bacteria can mutate very easily through the exchange of genetic material. Some bacterial species cannot be isolated. New bacterial species are discovered in less period of time and some species fail to grow on the growth medium due to lack of information. Till now only one percent of bacterial species have been cultivated.
Thus, true is correct.
Answer:
B. Ecdysozoa.
Explanation:
Ecdysozoa is the large group of animals that undergo the process of ecdysis which can regularly shed their outer skin made of the cuticle. This process of shedding the outer skin is also known as molting which is observed in the species of the nematodes and the arthropods.
In the given question, since the new species shed their outer skin which is a characteristic feature of the Ecdysozoa, therefore, the new animal species belongs to the Ecdysozoa.
Thus, Option-B is the correct answer.
Answer:
Explanation:
Red blood cells contain enormous amounts of a protein called hemoglobin. This iron-containing molecule binds oxygen as oxygen molecules enter blood vessels in the lungs. Hemoglobin is also responsible for the characteristic red color of blood.
The statement that is true about renewable energy resources is that there are endless supplies of all renewable energy resources (option B).
<h3>What is renewable energy resource?</h3>
Renewable energy is the energy that is collected from renewable resources such as;
- wind power
- hydropower
- solar energy
A renewable resource is that natural resource that is replenished by natural processes at a rate comparable to its rate of consumption by humans or other users.
This suggests that renewable resources have an unlimited supply and will likely not be exhausted. This is unlike the non-renewable counterparts like crude oil, gas etc.
Therefore, the statement that is true about renewable energy resources is that there are endless supplies of all renewable energy resources.

Answer: 1, 2, 4 are accurate.
Explanation:
1. Joe is on a hill (on a trail) above the ocean. The beach and ocean are at similar altitudes. Therefore Joe is at a higher altitude than if he was at the beach.
2. Since Joe is on a hill, he has a higher altitude than at sea level. Air at a higher altitude has lower density because there is less air "ontop" of itself than at lower altitudes. As well, his hill is above the ocean, which means there is a lot of water, making the air more humid than where he is. Humidity also makes air denser.
4.The air pressure will decrease if Joe goes up to higher altitudes because there will be less air on top of itself.
