Hey there!
They search for water. When there is water, life can thrive. Water comes before oxygen and other things humans need to survive, because “life” means just what it sounds like. It can be large aliens or microscopic bacteria. Therefore, when there is water, there could be life, and that’s why astrobiologists look for it.
Hope this helps!
The middle temporal visual area (MT or V5) is the brain area near the occipital lobe that has been shown to become active when motion stimuli are perceived, and when the direction of an object's movement is accurately detected. The middle temporal visual area is an area of extrastriate visual cortex and it is connected to a large collection of cortical and subcortical brain regions. This area is composed of high concentration of direction-selective motion stimuli which play important roles in the perception, integration of motion and in the control of some eye movements.
Answer: B. Modern bird species share many genetic similarities.
Explanation:
When organisms are said to have a common ancestor, it means that they share many genetic similarities but are not identical due to evolution and cross-breeding. For instance, siblings may have the same parents but they will not be genetically identical even though they have a lot of similar traits owning to their parents have different traits.
The same is true for birds. They share the genetic characteristics of their common ancestor but as time went on and evolution took place, they changed in some ways and so are no longer genetically identical.
