The statement "<span>Bright-field microscopes are used for most microscopic work. " is true.
</span>Bright-field microscopy<span> is the simplest of all the optical</span>microscopy<span> illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light and contrast in the sample is caused by absorbance of some of the transmitted light in dense areas of the sample.</span>

I am pretty sure that planet A will move faster and i know it will have a smaller orbit then planet B
(1) reproductive hormones
(2) carbohydrates
(3) antibodies
(4) biological catalysts
Answer and Explanation:
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc.
Carbohydrates are molecules from which our bodies derive energy in the form of ATP.
Antibodies protect our bodies from the invasion of foreign particles (pathogens)
Biological catalysts, or enzymes help our body speed up and perform all of the reactions that need to be done such as cutting and copying DNA. Therefore, choice (4) is the correct answer choice.
