Answer:
The correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Explanation:
Scientists could not use DNA evidences to make a complete phylogenetic tree of Icthyosaur as there are no blood samples or other DNA molecules to create DNA printing or mapping to create phylogeny with the modern dolphins. They only can be make similarities based on the morphological characteristics of these two groups.
Thus, the correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree

Answer:
The correct answer will be-
1. Pupil
2. Retina.
Explanation:
Organisms are able to see the world around them thorugh the sense organs called the eyes.
The structure of eye contains various modified structure which include the membranes and the attached muscles.
When light enters the light through the dome-shaped structure called cornea which contains the convex lens converges the light and light enters the hole called pupil through which light enters and strikes or get focused on the retina present at the back of the eye.
The pupil is attached to the ciliary muscles which dilate and contracts in the response of the intensity of light as during high light intensity, the pupil constricts whereas during the low light intensity the pupil dilates to allow the maximum amount of light.
Thus, pupil and retina is the correct answer.
Answer:
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism! Hope this helps! you can simplify this answer!
Explanation:
<span>Sheree observed an amoeba feeding by engulfing the prey with its false feet or pseudopods. This process is known as
phagocytosis.
The term comes from Greek and means: <em>phagein = to devour, kytos = cell, -osis = process, </em>so it literally means that it refers to a process in which a certain type of a cell (in this case, an amoeba) devours or eats another thing.
