A Scanning Electron Microscope (SEM) should be used by Sherman to try to see the 3-dimensional shape of a virus in the patient's sample.
SEM is a type of electron microscopy that can scan the surface of the object to be viewed with the help of the beam of electrons and can give clear and detailed structure of that object. It produces the image in 3-dimension.
The inaccurate statements are:
- Warm, moist air goes up the mountain on its leeward side, where its water content condenses to precipitate as rain or snow;
- This side is called the windward side and, compared with the leeward side, receives hardly any rainfall;
In the description, the windward and the leeward sides of the mountain are mistaken, or rather have switched positions.
The windward side is the side where the warm, moist air where the water condensates and results in rainfall or snow. Thus this is the side of the mountain that is wetter and is covered with denser vegetation.
The leeward side is the side that doesn't receive warm and moist air, and the amount of precipitation is usually very low. This makes the leeward side very dry in most cases, and very often it is the reason for the formation of arid and semi-arid areas.
Answer:
In the adult organism, mitosis plays a role in cell replacement, wound healing and tumour formation. Mitosis, although a continuous process, is conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase and telophase.
Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

2nd law—> the force exerted by the engine can be found if you know the car's mass and acceleration
3rd law—> the car applies a force to the ground and the ground exerts an equal but opposite force on the car
Answer:
The cell membrane is semi-permeable. It allows some molecules to enter easily inside the cell whereas some molecules are blocked from entering the cell.
Small, polar molecules and hydrophobic molecules enter easily through the cell membrane. But large molecules and ions cannot easily move inside the cell membrane.
A hydrophilic substance like the substance L mentioned in the question enters the cell membrane through the help of carrier proteins. The substance attached to the large protein might enter through active or passive diffusion but it can only enter the cell by attaching to carrier proteins.
