Answer:
__ It implies that prokaryotes existed before eukaryotes, and
__ It implies that eukaryotes evolved from prokaryotes.
Explanation:
The prefix pro- can mean "before". By using the term prokaryote one can tend to think that procaryotes preceded eukaryotes.
Preceed as existed before them, or as an evolutionary point of view.
The correct answer is Sideways.
Answer:
Daisy's episodic memory is impaired, but her semantic memory is intact.
Explanation:
Episodic memory is the type of memory that holds events experienced by the person. That is, it is the memory that holds the places the person went, important dates, events that occurred and other things that the patient was present at the moment. If Daisy can't remember what she did last week, how the accident happened, or any of her childhood experiences, then her episodic memory is compromised.
Semantic memory allows humans to communicate with language. In semantic memory, the brain stores information about words, what they look and represent, and how they are used in an organized manner. Daisy is able to read, write and speak accurately and remember the names of countries, things, places and famous people, that means her semantic memory is intact.
The correct order of the following events on the mass flow of materials in the phloem is:
- Leaf cells produce sugar by photosynthesis.
- Solutes are actively transported into sieve tubes.
- Water diffuses into the sieve tubes.
- Sugar moves down the stem.
Correct answer: letter C.
This is because the mass flow of materials in the phloem must pass through all these processes in a consecutive and orderly manner, from the cell to the stem, in order to allow nutrients and other vital materials to reach from the plant roots to the leaves and fruits.
<h3>How is this transport of nutrients and other vital materials achieved?</h3>
This is accomplished by the transport of solutes through the phloem's network of channels, which contain fluids, mineral salts, vitamins and other nutrients essential to plant health. Mass flow also helps distribute oxygen and carbon dioxide to all parts of the plant. These materials are necessary for plant respiration and growth.
