Answer:
100,000 TMV
Explanation:
Length of one TMV is 300nm. Length of paper clip is 3.0cm. First step is to convert either value to match the units of other.
So 3.0cm to nm is 3.0 * 10^7 = 30,000,000nm
SO now it becomes simple because we just divide the total length by length of TMV to find number of particles that can fit:
30,000,000/300 = 100,000 TMV
Answer:
A
Explanation:
When you gather the patients data it will help to know its inherited or what
Answer:
<em><u>H1: false, the observations of the molecules do not support the hypothesis...</u></em>
Explanation:
The cell membrane is comprised of a phospholipid bilayer, proteins, and cholesterol. These components help the membrane to maintain its selective permeability and concentration of solutes and water.
The lipid molecules have polar hydrophilic heads and hydrophobic tails. These only readily allow for the movement of small non polar molecules. Other substances, like charged ions and large molecules require transport proteins to move in and out of the cell. Hypothesis: H+ is small and should be able to move freely through the membrane, While glucose is large and cannot move freely
- Observing H+, despite being very small these cannot easily pass through the membrane. They require transport proteins called channels for their free movement or passive movement across the membrane.
- For glucose, these molecules pass through specialized channels in facilitated diffusion. They move down their concentration gradient into the cell. To move out of the cell against its concentration gradient glucose requires ATP for active transport.
- Cortisol, is a large steroid hormone, taken into the cell by simple diffusion across the lipid membrane, down its concentration gradient.
Phagocytosis would enable a white blood cell to ingest a bacterium
Phagocytosis is a special form of endocytosis by which cells ingest solid substances including microbial pathogens to produce an internal compartment known as a phagosome. Cells that undergo this process are called phagocytes. The white bold cells of the immune system protect the body against invasion by pathogens such as bacteria. They perform this function by phagocytosis.
