Answer:
Your question is incomplete, but I attached the exercise with the possible phylogenetic trees and all the information that your question missed. I hope it helps you.
The most parsimoniuous phylogenetic tree is c) phylogenetic tree III
Explanation:
The most parsimonious tree is the one that takes fewer base-change events, it's the simpler one. In this case it could be tree III or tree IV. But, if we look at the genetic evidence, group 2b and 3 are nearer than 2b and 2a; group 4 and 5 are also closely related. So it is possible that the group 2b, as well as groups 3,4 and 5, diverged from group 2a. So the answer is tree III.
The most parsimonious phylogenetic tree is the one that requires the least changes in the A, C, G, T genetic sequence coding for eye growth, thereby presenting the simplest explanation of evolutionary relationships among the alien species.
The question is asking which of the four possible phylogenetic trees represents the most parsimonious, or simplest, explanation of the shared genetic sequence for eye growth among the alien species. The most parsimonious tree would be one that requires the least amount of evolutionary change in terms of the genetic sequence. This would be determined by comparing each tree and the associated genetic sequences in the way they separate the six groups of aliens and particularly how they divide the single-tail three-eye group. This should provide the simplest explanation of evolutionary relationships based on the alien's genetic code of A, C, G and T.

B. red dwarf
C. white dwarf
D. red giant
E. red supergiant
The answer is D. The life cycle of a star is dependent on its mass. Stars by forming at nebulas as protostars. When the sun exhausts hydrogen fuel at its core, the core begins to fuse helium to carbon and the core becomes hotter but smaller. The outer layers are pushed outwards and the sun becomes larger and paler. Later, the helium fuel begins to run out and the sun loses the outer expanding layers into a planetary nebula. The remaining core is a white dwarf.
Stars that are 10 times our sun's solar mass just explode to supernovas when their hydrogen fuel is exhausted.
Answer:
a. activation of the sympathetic autonomic nervous system by the new experience.
Explanation:
The sympathetic division of the autonomic nervous system generates a flight or fight response. This is a series of physiological processes that start when a person has any stress, new experience or emergency conditions such as the first diving trip. One such response produced by activated sympathetic division is increased heart rate to pump more blood and deliver more oxygen to body cells and tissues. Also, the person experiences an increased breathing rate to compensate for the increased oxygen demand.
Kelp plants have been known to grow up to b. 2 inches per day. Correct option is B.
Kelp is a type of marine algae that belongs to the group of brown algae known as Phaeophyceae. It is a multicellular organism that forms large underwater structures known as kelp forests in shallow, nutrient-rich coastal waters. These kelp forests are highly productive and provide essential habitats for a diverse range of marine organisms.
Kelp has an impressive growth rate compared to many other plants. Its growth rate is influenced by several factors, including environmental conditions and the species of kelp. Some kelp species can grow incredibly quickly under optimal conditions. Kelp is a type of large brown algae that grows in underwater "forests" in shallow, nutrient-rich marine environments. They are known for their rapid growth rates, with some species capable of growing several centimeters or inches per day under optimal conditions.

Okay let me settle this now... I, just as most of you, hate the giant long explanations, most people are here for the answer, so I'll do us all a favor here... It's 14.
