Answer:
I would split these organisms into two paraphyletic groups: 1-one group composed of wolfs and dogs, and 2-one group including all three species (dogs, wolves and cats).
Explanation:
A clade is by definition a monophyletic group, it means that a clade is a group composed of a common ancestor and all its lineal descendants. Moreover, a paraphyletic taxon is a group of organisms that share a most recent common ancestor and some of its descendants. In this case, wolves and dogs can be grouped to form a more inclusive group since both species belong to the same genus (Cani), while dogs, wolves and cats can be grouped to form a major group because these three species are mammal species. In consequence, in this case, we have two paraphyletic groups supported by synapomorphic (shared, derived) characters, since wolfs and dogs represent only two species within genus Canis, while dogs, wolves and cats represent three species within class Mammalia.
Answer:
It is an extrusive igneous rock
Explanation:
Based on the physical appearance, the geologist can make an accurate conclusion about the rock's formation and in which type of rocks does it belong. The fine-grains made up of small crystals give away clues about the formation of the rock. Fine grains with small structures occur when the lava reaches the surface and cools off very quickly, thus not giving the crystals enough time to grow, so they are very small. The geologist can classify this rock on base of this information as an igneous rock, as it has been formed from lava, and as an extrusive igneous rock, as the fine grains and small crystals only occur when the lava cools of quickly on the surface.
C. 70% of the world is covered by the ocean
Answer:
a discovery by a human being
Explanation:
The correct answer would be a discovery by human being.
Penicillin existed in nature and was only discovered, albeit accidentally, by Alexander Fleming.
It is different from<u> technological innovation because the latter requires the synthesis of products that are not in existence already or improvement on a product that has been created before</u>.
Discovery is also different from advancement in technology. <u>The latter refers to the process of inventing, innovating, and spreading technological processes in society.</u>
Discoveries are usually natural and are not in any way an invention. However, advancement in technology can aid discoveries.
