Mars' surface is largely covered with basalt, a volcanic rock covering much of Earth's surface as well. Earth has large amounts of granite in its crust, which Mars appears to lack.

A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.

B. White blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes.

C. White blood cells have many lysosomes because they need lots of ATP to help carry oxygen.

D. White blood cells have many lysosomes because they need to produce lots of proteins to help build muscle.

Answers

Answer:

Explanation:

A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.

Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.

White blood cells have an abundance of lysosomes because ( B ) : White blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes.  

White blood cells function as a defensive cells in the Human body and to perform this defensive duties against bacteria and other pathogens they need a lot of lysosomes. these lysosomes are contained in the vesicles that are formed when the white blood cells engulfs a bacteria and these lysosomes ( hydrolytic enzymes ) digest the pathogen, preventing the infection that could have caused by the pathogen.

Hence we can conclude that white blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes

how to use a microscope> Everything I need to know

Answers

Do not touch the glass part of the lenses with your fingers. Use only special lens paper to clean the lenses.
Always keep your microscope covered when not in use.
Always carry a microscope with both hands. Grasp the arm with one hand and place the other hand under the base for support.

Step 1: Set Up the Microscope. ...
Step 2: Clean the Lens. ...
Step 3: Prepare a Slide. ...
Step 4: Insert the Slide. ...
Step 5: Set Up for Viewing. ...
Step 6: Set the Light Control. ...
Step 7: Focus the Microscope. ...
Step 8: Increase Magnification.

Answer:

Keep in mind this changes from microscope to microscope.

Explanation:

On most classroom microscopes, there will be two knobs on either side of the scope.  These will increase or decrease the height of the "stage", which is how you "focus" the microscope.  The larger knob will move the stage the most, and thus, is called the coarse focus.  The smaller knob is called the fine focus, and, you guessed it, will move the stage the least.  There are usually three "objective lenses".  Each will have a different magnification and will be listed on the lens itself.  It rotates around the "revolving nosepiece".  MAKE SURE THAT THE SLIDE IS LOWERED BEFORE ROTATING THE LENSES!!!!  If you don't you WILL break the slide and you WILL get death looks from the teacher.

On the stage, there are two clips.  They move NOT up and down, but they spin.  what you want to do is to move the slide into the clips.  They will not break if you do not bend them more than what the slide will bend them to.

The technique for focusing the microscope is really easy once you do it a few times.  After making sure that the microscope is plugged in and the light on and the slide and lens in the lowest position/magnification (!) move the coarse focus knob so that the object in the slide is just visible.  Once you do that, from there use the fine focus knob to make the object most visible.

These instructions vary slightly from model to model of microscope, but the picture below is very accurate and everything I warned you about is for all microscopes.
