An ion is not a subatomic particle
Answer:
D: two jaguars per thousand hectares.
Explanation:
Population density refers to the computation of population by unit area. It is usually implemented in living organisms, generally in humans. It is a key geological term. In easy form, population density implies to the number of people existing in an area per square kilometer or hectare, etc.
So, two jaguars per thousand hectares is an example of population density as it involves the number of jaguars (population) per thousand hectares (per unit area).
Answer:
D
Explanation:
The correct answer would be that <u>digestion increases as the volume of the enzyme increases.</u>
<em>Protein digestion is catalyzed by the pepsin enzyme and aided by HCl. The combined actions of both substances form the basis for the digestion of protein in the stomach. Hence, one would expect the digestion of the boiled egg white to increase with the increase in the volume of the enzyme - all other factors remaining constant.</em>
The correct option is, therefore, D.
Answer:
plasma membrane, ribosomes, cytoplasm, and DNA
Explanation:
Answer:
A Comparison of Cells Commonly Seen in Lab
Bacteria: prokaryotic. Very small. No nucleus, no chloroplasts, no mitochondria. Do have a cell wall.
Plant cells: eukaryotic. Relatively large. Have a nucleus, have mitochondria, sometimes have chloroplasts. Have a large central vacuole and a cell wall.
Animal cells: eukaryotic. Relatively large. Have a nucleus and mitochondria. Never have chloroplasts. Lack a cell wall, and have no central vacuole.
...
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
This cell was alive and at 1000x magnification when it was photographed.
