Answer:
In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats.
Answer:
One advantage of models is that all the mice are exactly alike except for color, enabling the control of all variables except the one being studied. Models are also easier to work with than live mice. One disadvantage of using models is that they do not have the same smell and behaviors as real mice.
Another advantage is that models can be reused for the experiment for a longer period of time with less maintenance.
The hypothetical cell will approximately contain 94 percent (94%) of water.
- If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.
- If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.
- Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.
- In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).

Whelp, it is definitely not D.
I would say B.
there was no Paleogene period.
