Explanation:
Believe it or not, _ENERGY_ within an ecosystem is not transferred back and forth between all levels. Energy begins with the SUN and flows in one direction to PRODUCERS to CONSUMERS and, finally, to DECOMPOSERS.
A FOOD WEB represents all the possible paths for energy to flow within an ecosystem, whereas a FOOD CHAIN represents just one path. When drawing a diagram of a food web, you always draw the arrow in the direction of ENERGY FLOW. For example, an arrow from a PRODUCER to a CONSUMER.
Organisms at all trophic levels eventually die. MICROORGANISMS such as bacteria and fungi, process the stored energy in dead plants and animals and transfer part of it to the soil that the plants will use as nutrients, and the energy cycle continues.
Answer:
<em>B: The drug is a small charged molecule</em>
Explanation:
Substances can passively diffuse in and out of the cell via the cell membrane in two ways;
- Simple diffusion
- Facilitated diffusion
The cell membrane allows small molecules or ions to freely diffuse across it in response to concentration difference between the inner and outer parts of the cell membrane. This is known as simple diffusion.
In facilitated diffusion, special proteins in the cell membrane, known as channel/carrier proteins binds with molecules and facilitates their diffusion across the cell membrane by carrying them through special channels in the membrane.
Hence, to support the alternative hypothesis that the new drug will exhibit simple diffusion across the plasma membrane, the drug should be a small charged molecule.
<em>Correct option: B</em>
The answer is C. When a vacuole is filled with water, turgor pressure exist, it can keep the cells turgid and therfore to make the plant stay upright and prevent it from wilting.
Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
- <em>The cell represents the basic unit of all life.</em>
- <em>All living organisms are made up of cells.</em>
- <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>
Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.
It would be 2. it emits all wavelengths in the electromagnetic spectrum
