Compare and contrast the structure and function of a compound light microscope and a scanning electron microscope. Be sure to discuss the structure and function of each as well as the function and usefulness of each when examining a specimen. (5 points)

Answers

Answer 1
Answer: Both the compound light microscope and the scanning electron microscope are devices used for visualizing structures too small to see them with the eye. But, they differ in many ways. Some of them are:

* → The light microscope is compact, handy, and simple to use.
  → The electron microscope is large, complicated, and requires technical skills.

* → The light microscope can be used for observation of both live and dead specimens.
   → The electron microscope can be used for observation of only dead specimens.

* → The light microscope uses light rays for illumination of the specimens.
  → The electron microscope uses electron beams to view specimens.

* → The light microscope has a magnification of up to 1,500 times.
  → The electron microscope has a magnification of up to 1,000,000 times.

→ The light microscope has lenses made of glass.
  → The electron microscope has lenses made of electromagnets.

Eukaryotes are organisms who is containing a nucleus, cells and other organelles that are enclosed with membranes just like the prokaryotes does. Eukaryotes are able to reproduce asexually through the process of mitosis and sexually through the  process of meiosis. 

"Ribosomes are described as the site of protein synthesis. Ribosomes consist of RNA and protein combined into a very particular shape. As a ribosome moves along an mRNA transcript, amino acids are joined together by peptide bonds. The formation of peptide bonds is facilitated by rRNA in the ribosome. Thus, rRNA can be described as a(n)"

Answer:

Catalyst

Explanation:

Translation is the second process of gene expression which occurs in the ribosomes of living cells. The ribosome is a complex of Ribosomal RNA (rRNA) and proteins. Translation occurs when ribosomes attach to the transcribed mRNA molecule to read its codons using the transfer RNA (tRNA's) anticodon. The tRNA then carries amino acid that corresponds the codon it reads to the growing polypeptide chain.

In this process, amino acids are attached to one another forming a peptide bond. This linking of one amino acid to another is facilitated by rRNA's as it helps catalyzes the reaction like an enzyme. Ribosomal RNA catalyzes the reaction that forms a peptide bond between the amino acid in the A site of the ribosome and the growing polypeptide (future protein) in the P site.

Sloths have less muscle than other mammals their size in order to _______.a. conserve energy
b. maintain a lower body weight
c. digest their food faster
d. maintain a higher body temperature

Answers

The specific adaptation of the sloths to their niche is energy conservation: they survive by trying not to loose any energy and trying not to move too much. They have less muscle because they don't need it: their adaptation is to move less. So the correct answer is to a) conserve energy.

Answer:

A) Conserve energy

In the city of Birthville, an elderly midwife who has been working at the community center for several years noticed that there were no deliveries in the month of May in a particular year. In her discussion with the matron of the clinic, she said, "There were no deliveries in May of that year." In scientific process, her response can be classified as:_________-

Answers

Deductive reasoning plays an essential role in attaining a valid conclusion during a scientific process. It is considered a fundamental form of valid reasoning.

The correct answer is deductive reasoning in the given case as the elderly midwife has no deliveries this year.

Deductive reasoning-

Deductive reasoning is the process of reasoning from one or more statements (premises) to succeed in a logical conclusion.

Deductive reasoning goes within the same direction as that of the conditionals and links premises with conclusions. In deductive reasoning, there is no uncertainty.

The Deduction begins with a hypothesis or a usual statement that helps in finding the possible ways to attain a particular and valid conclusion.

Deductive reasoning is used in examining hypotheses and theories in a scientific method. Deductive reasoning generally follows certain steps before reaching an eventual inference.

It plays an essential part in the process of making decisions. In arguments and decision-making, it's used as a base to supply factual proof.

Thus, in the given case, the response of the midwife can be classified as deductive reasoning.

Which macronutrient is vital for every function of the body? A.
water
B.
fats
C.
proteins
D.
carbohydrates

Answers

The correct answer is Water.

Water is the most important macronutrient for performing all the vital functions of the body. It does not provides energy to the body. The main function of water is to provide a medium for all the metabolic processes that takes place in our body. It helps in absorption of macronutrients but has no nutritive value of its own.Elements such as chloride and fluoride reach the body through this medium.
