Answers

Answer 1
Answer: Active transports is actively done to remove or add something that would not normally move there in comparison to passive which occurs on its own without the need for energy

What factor determines when a species is considered invasive?a. It has positive environmental impacts.
b. It is environmentally damaging.
c. It spreads outside its native range.
d. It spreads within its natural range.

Answers

Answer: b. It is environmentally damaging.

An invasive species is a kind of living organism such as amphibian, insect, bacteria, fungus, plant or even the seeds or eggs of the organism that is not native to a region or ecosystem but introduced either accidentally or by the migration of the species in search of food, shelter, habitat and mates. The invasive species has the potential to compete with the native species, can harm the environment, and health of the human or other living species.

The invasive species spread rapidly after starving the population of native species for food, shelter and for other needs. The invasive species can affect the availability of water and can damage the quality of soil nutrients. Once it is introduced into a habitat it changes the environmental condition of that habitat adversely.

A moving hang glider has ____ energy, which converts to _____ energy once the hang glider stops.

Answers

A moving hang glider has kinetic energy, which converts to potential energy once the hang glider stops.

Answer: kinetic , potential

Explanation: According to the law of conservation of energy, energy can neither be created nor be destroyed. It can only be transformed from one form to another.

Kinetic energy is the energy possessed by an object by virtue of its motion.

Potential energy is the energy possessed by an object by virtue of its position.

Thus a moving hang glider possesses kinetic energy which is converted to potential energy when it stops.

How long does it take for a new species to arise? Have we ever witnessed a new species arising - like in any laboratories or otherwise - possibly with creatures with short life spans? Does it happen all the time, or is it incredibly rare?

Answers

Arising of a new species is not a rare thing. Organisms are always in a competition to survive long. Speciation, as what they call it, is happening from time to time because organisms evolve in order to adapt to the environment where they are in. However, this process is a slow one thus it is almost impossible to see a new species arising.
