Scientists are going to explore the ATMOSPHERE of Kepler-186f next. This is because there are still no known inventions that can analyze the atmospheric characteristics of this planet and conclude whether it is habitable or not. Its location is too far for our existing telescopes to fully analyze its atmosphere. Scientists are all on their toes to discover this planet's abilities for habitation by conceptualizing an instrument that could measure such.

Explanation :
Tapeworms do not have a digestive tract. Instead, they absorb their nutrients from the gut contents of the host directly through their outside surface, tegument.
<span> b. Karyotype analysis or karyotyping is a technique that </span>shows the profile or representation of a person's chromosomes. Scientists arrange each chromosome per size, centromere position and banding pattern. This is done to detect genetic abnormalities.
Answer:
The mass number is the sum of protons and neutrons in an atom.
The nucleus makes most of the an atom and in the nucleus are the protons and neutrons. Although atoms are also made up of electrons, they are so small that the mass of an electron is negligible. So the mass of an atom is determined by the protons and neutrons instead.
Example:
An oxygen atom has an atomic number of 8 and has a mass number of 16.
The atomic number indicates also th number of protons. Since the atomic number of oxygen is 8, then it has 8 protons.
So if the mas number of oxygen is 16 and the number of protons is 8, this wold mean that an Oxygen atom has 8 neutrons.
Mass Number = Protons + Neutrons
16 = 8 + n
16-8 = n
8 = n
The answer is <span>B. It can reproduce quickly.
A single-celled organism, as its name explains, consists of only one cell. This cell must be small because, in a large cell, it would be needed a great time for information, nutrients and other molecules to travel from one part of the cell to another (choice A. is eliminated). That small cells are able to reproduce quickly because their dimension allows them to divide to new cells quickly (even 20 minutes). Still, although it is only one cell it must maintain its structure (choice C is eliminated), and cannot tolerate all environmental conditions (choice D is eliminated).</span>
