Answer:
<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>
Explanation:
As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.
Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.
It is distinctive, widespread, abundant and limited in geologic time. Because most fossil<span>-bearing rocks formed in the ocean, the major </span>index fossils<span> are marine organisms. That being said, certain land organisms are useful in young rocks and in specific regions.</span>
Answer:
Anatomy
Explanation:
Based upon the presence and larger size of the eyes of the cephalopods, you could guess they have a more complex ANATOMY system.
Answer: c) from an area with a high concentration of water to one of lower concentration
Explanation:
Microscopically, we can interpret osmosis as the passage of water through holes in the membrane. These holes are small enough to allow water to pass through, but not to the ions that carry a layer of hydration, that is, a layer of water molecules around them. Water flows through the membrane in both directions. However, the occurrence of osmosis indicates that the flow is more intense in the direction of the less concentrated medium to the more concentrated. Thus, there is an effective flow of water in one of the senses, called osmosis, from an area with a high concentration of water to one of lower concentration.
