1. One of the main reasons for the extinction of the trees in the Eastern Island is the extinction or sudden demise of the birds that carried the seeds to different places. Some of the human activities would have also led to the process of extinction, like the trees were being cut to construct canoes and to use as tools in order to erect statues, and to burn them for warmth.
2. There was a need to farm the trees and manage them in a proper framework. For example, if one is having 100 trees, then one should use 33 and then plant 33 seeds, and should always keep 34 intact. One should have not used all the trees at once.
Answer:
<u>Option -</u> An open circulatory system inside the adults.
Explanation:
- A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. A knowledgeable zoologist should predict that the adults of this species would also feature <u>an open circulatory system</u>.
- Most of the invertebrates like the insecticides have the open circulatory system, as the system has no specific pathways for the transportation of the materials and other essential nutrients through the medium but they have a more different mechanism in order to provide the sufficient materials to survive.
<span>Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart. </span><span>
This shows that the animals are similar and that they develop similarly, implying that they are related, have common ancestors and that they started out the same, gradually evolving different traits, but that the basic plan for a creature's beginning remains the same.</span>
Answer: Two electrons and a hydrogen ion
Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.
