Answer: The lymphatic system is composed of lymph vessels, lymph nodes, and organs. The functions of this system include the absorbtion of excess fluid and its return to the blood stream, absorption of fat (in the villi of the small intestine) and the immune system function.
Explanation:
B. flagellum
C. cytoplasm
D. nucleus
Answer:
D. nucleus is the answer
Answer: d. venom
Explanation:
The copperhead and the rattlesnakes are both pit viper snakes that means they detect the minute differences in temperature by sensing the heat through their eyes and nostrils. Thus these snakes accurately detects the sense of heat of a particular prey. Their venom is a potent toxic which can kill a prey in single bite.
Therefore, because of the presence of deadly venom present in them these snakes exhibit very few natural predators.
Both conduction and induction involve a movement of electrons. Conduction is the transfer of electrons from a charged object to another object by direct contact. Induction does not involve direct contact. Instead, induction is the movement of electrons from one part of an object to another as a result of the electric field of the second object. What is the difference between conductive and non-conductive? Conductive materials are good conductors of heat or electricity. Nonconductive materials are not good conductors of heat or electricity. I hope this helps! :)

Explanation:
Electron microscopes' specimens can be stained for contrast, while light microscopes' specimens appear black and white
Electron microscopes are used for dissections, while compound light microscopes are not.
Electron microscopes use electron beams and electromagnetic lenses, while compound light microscopes use light and ocular and objective lenses.
Explanation:
D) Electron microscopes use electron beams and electromagnetic lenses, while compound light microscopes use light and ocular and objective lenses.
Microscopes are instruments used for viewing microscopic cellular structures, not visible with the human eye. With an arrangement of lenses, and manipulation of light or electrons, these magnify very small objects. Light microscopy uses light and multiple lenses, while electron microscopes use electrons. These create larger images of objects.
While light microscopes with a resolution power of 0.2 um can view objects at a magnification x1000, electron microscopes are capable of a much smaller resolution at 0.5 nm and magnification of x100,000.
The wavelengths of light in the visible part of the eletromagnetic spectrum (visible light is between 390 nm and 760 nm,) are manipulated in light microscopy. The visible light is passed through the biological sample where it bends, as it travels through multiple lenses. This is often usable on live organisms. Thus the observer can look at cells as they undergo division or locomotion. Resolution describes the shortest distance, where two objects are still visible as distinct bodies. With light microscopes, one may view objects between a millimeter (10-3 m) and a fraction of a micrometer at 0.2 thousands of a millimetre or 2 x 10-7 m.
Unlike light microscopy, electron microscopy involves the manipulation of electrons through the apparatus, under a vacuum. As the beams of electrons have shorter wavelengths than light particles, the images produced have higher resolution and can be seen more clearly. The sample is meticulously prepared, and is typically not made up of live cells; EM can be used in viewing subcellular components, such as organelles and can view structures as small as atoms at 1/10 000 000 of a millimeter, 10-10 m.

The correct option is (D) Electron microscopes use electron beams and electromagnetic lenses, while compound light microscopes use light and ocular and objective lenses.
A microscope is an instrument that is utilized to amplify small objects. A few microscope might be utilized to notice an object at the cell level, allowing researchers to see the state of a cell, its nucleus, mitochondria, and different Organelles.
Electron Microscope utilizes a light emission and their wave-like qualities to magnify an object's image. The Light Microscope employs visible light to detect tiny objects.
Hence, the correct option is D.
