Scientific knowledge is always changing. At one time, the kingdom was the
highest level of
classification. Today, the highest level of classification is the domain. Two of
the domains, Bacteria and Archaea both contain microscopic prokaryotic
organisms. What would be the best reason for scientists to separate the
prokaryotes?
A)There were too many species of prokaryotes to only have 1 domain for them.
B)It was determined that neither have chloroplasts.
C)Both organisms do not contain organelles.
D)Research showed differences in living environments.

Answer 1

Answer:

d

Explanation:whater

Answer 2

Research showed differences in living environments is the best reason for scientists to separate the prokaryotes. Therefore, option (D) is correct.

What are prokaryotes?

The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.

Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.

A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

How do you think the Law of Universal Gravitation State connects why apples fall down and planets circle in orbit?

Answers

Apples are drawn to a massive object, like the earth, and fall down under a gravitational constant. On the other hand, planets revolve around a more massive object under the same premise. It’s the same idea, just one follows a linear path, and the other has a uniform circular motion path because other forces are acting on it. In other words, the planets ARE still falling, but the sun is also pulled by them so they just keep dancing.

What is crossing over?

When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up.

The same genes may be present on the two chromosomes in different versions. The genetic material in the germ line can switch places, a process is known as crossing over.

Pairs of chromosomes from each parent align to allow similar DNA sequences from the paired chromosomes to cross over one another during the development of egg and sperm cells, commonly known as meiosis.

Therefore, the percentage that will be speckled is 20%.

The company begins operations on April 1, 2017 by purchasing 100 rulers at $6 each; 70 mechanical pencils at $8 each; and 120 notebooks at $7 each. Using the information above, calculate the book value (i.e., balance sheet value) of the three categories of inventory that Bloomfield would report as of April 1, 2017. Rulers: Pencils: Notebooks: Total: Now assume that Bloomfield incurs the following additional expenditures to acquire the inventory on April 1, 2017: The 100 rulers have a flat shipping fee of $15. The mechanical pencils are imported; each unit is subject to an import duty of $0.50. The notebooks ship with a flat fee of $12 plus $0.10 per unit.

There is about a 60% chance the crew will be successful in repairing the arm back to an Excellent condition. Otherwise, they have to try again the next day to x it.
