Answer: second
Explanation:Early humans most likely experienced changes in climate forcing migration to find animals for food, changes in climate alternating rivers with droughts and floods and changes in environment causing animal habits changes.
Explanation:
All the changes that early humans could have experienced, I think, are related to the changes that animals and the lands could have suffered. They lived much more closer to them than we do now; now we sometimes don't realize how global warming is affecting our planet because we are not that close to the lands and the crops and we don't usually raise animals for our consumption, we just buy at the shop. But, early humans could sense every change related with that because this was the way they lived. So, migration to find animals, changes in climate alternating rivers with droughts and floods and changes in animal habits are the ones I believe they could have suffered.
<u>ANSWER:</u>
The correct option is C: Skin that blends with green plants. Most animals in rain forests are green so that they can camouflage and appear like plants.
<u>EXPLANATION:</u>
- Adaptation is the way in which animals survive in different climatic conditions and different regions. In rain forests, to protect themselves and to find food, most animals are green in colour.
- This prevents the animals from being spotted easily and therefore they are protected from hunters and other animals that eat them. This way, the animals can also find their prey and catch it easily.

Answer:
The plasma membrane is the thin, flexible boundary between a cell and its environment. Plasma membranes with less cholesterol will have decreased fluidity at low temperatures and higher fluidity at high temperatures compared to the membrane with more cholesterol. This is because it prevents the fatty acid tails from sticking together!
Option(D) is correct
A scientist creates a new kingdom based on the fact that a discovered organism has unique characteristics and he has never seen a similar organism before.
<u>Explanation</u>:
A new kingdom can be created if the organism that has been discovered is entirely different from the organisms existing earlier. If the organism possesses features of any other organism existing earlier than it might be impossible to create a new kingdom.
This helps scientists to create a new kingdom or different species of plants or animals. It helps in the development of unique species that possess unique qualities.
