In A Quiz Competition, You Are Asked A Question Where You Have To Choose The Statement Which Is/ Are Incorrect? (1 Point) [A]. Squamous epithelium is made up of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue. [B]. The cuboidal epithelium is found in kidney tubules, thyroid vesicles and in glands. [C]. The main function of columnar epithelium includes absorption and secretion. [D]. None of the above
Answer:
[D]. None of the above
Explanation:
Epithelium are one of the type of four tissues found in living systems. They possess a variety of functions and are found to line/cover the surfaces of most organs. Epithelial tissues are classified based on the number of cell layers (simple and stratified) and shape (squamous, columnar, and cuboidal).
Based on their shape;
- Squamous epithelium are made up of scale-like flat cells that line the surfaces of alveoli of the lungs etc. They are of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue as stated in this question.
- Cuboidal epithelium contains cells whose shape are similar to that of a cuboid i.e. close width and height. They are located in the kidney tubules, thyroid vesicles and in glands like pancreas.
- Columnar epithelium are relatively thin and elongated in shape, hence, they are found in organs and surfaces whose function mainly is absorption and secretion.
Hence, NONE of the mentioned statements are UNTRUE

Which is one way that the movement of matter through an ecosystem is different from the transfer of energy?
A. Only the movement of matter involves living things.
B. Only the movement of matter flows in one direction only.
C. Only the movement of matter occurs in an unending cycle.
D. Only the movement of matter involves feeding relationships.
Answer:
C. Only the movement of matter occurs in an unending cycle.
Explanation:
Living organisms require both energy and matter for their growth and development. Nutrients are the nonliving matter of an ecosystem. Matter in form of nutrients moves from the soil to the plants, which absorb them using their roots. Matter moves to organisms called consumers when they feed on the plants and themselves consecutively.
When these organisms die, the matter goes back to the soil and the cycle starts again. Energy, on the contrary, moves in one direction. However, only the movement of matter occurs in an unending cycle.
Answer:
C. Only the movement of matter occurs in an unending cycle.

Why can’t two pyrimidines be paired with one anothr ?
Answer:
There are two reasons for this. The first reason is that the distance between the two strands of DNA is constant. Two purines together would be too big to fit in that distance, and two pyrimidines together would be too small. The second reason is that the bonding between purines and pyrimidines is very specific.

Which of the following represents a compound:
The root word “di” means “two,” so the word “diatomic” refers to _____.
A forces within the atom
B a molecule with two atoms
C negatively-charged electrons
D positively-charged protons
Answer:
B
Explanation:
Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning "two".
The word "di" means two, and "diatomic" means a molecule with two atoms that is present in Option B. Diatomic molecule may consist of similar atoms or may have different atoms, such as nitrogen oxide.
What is a diatomic molecule?Diatomic molecules are those that have two atoms within the molecule, such as hydrogen (H₂), nitrogen oxide, etc. In a single compound, there are many atoms that are present, and they make different bonds with each other, such as the covalent bond.
Aside from the covalent bond, there are other types of bonds, such as ionic bonds, but not all types of elements that are present in the periodic table can form the diatomic molecule. The homonuclear diatomic molecule is hydrogen, where two hydrogen atoms are present, and an example of the heteronuclear diatomic molecule is nitrogen oxide, where nitrogen and oxygen atoms are present.
Hence, the correct answer is option B, which is a diatomic molecule with two atoms.

What did Gould and Eldridge infer about the pace and timing of evolutionary change? (5 points)
a
Evolutionary change occurred gradually and constantly throughout time.
b
The pace of evolutionary change has slowed down over time and it only rarely occurs now.
c
Periods during which evolution occurred were always preceded by a catastrophe.
d
Long periods of stability were punctuated with periods of evolutionary change.
Answer:
d. Long periods of stability were punctuated with periods of evolutionary change.
Explanation:
Gould and Eldridge inferred that evolution occurred because of the sudden existence of new factors that force a certain type of species to adapt to the new situation. (Things such as sudden change in the environment, sudden change of the species' genetic composition that passed over during natural selection ,etc)
They believe this is why periods of evolutionary change happened in considerably shorter period of time right in the middle of periods of stability.

Explanation:
i took the test
Transfer RNA acts as a link (also called an adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that comprise a protein. Therefore, option (C) is correct.
What is the function of tRNA?Transfer RNA is an adapter molecule that is made of RNA and normally ranges in length from 76 to 90 nucleotides. Its primary function is to act as the physical link between the amino acid sequence of proteins and the mRNA that encodes them. Transfer RNA achieves this goal by transporting an amino acid to the ribosome, which is the component of a cell that is responsible for the synthesis of proteins.
The tRNA molecule is characterized by its characteristic folded structure, which consists of three hairpin loops that are arranged in the manner of a clover with three leaves. A sequence known as the anticodon is contained within one of these hairpin loops. This anticodon has the ability to detect and decode mRNA codons. Each transfer RNA (tRNA) has the amino acid that corresponds to it connected to the very end of it.

theyre quite terrifying to think about. Like the fall of humanity is scary. to think the offspring i have created or the people i have known have gone from decent people to incredibly corrupt. In "1984" by george orwell, the dystopian society he has created horrfies me. The idea that even your thoughts are monitered disrupts your self expression and how you interact with the world. To live in a world where you cannot do anything but basic busy work seems tactful. I bvelieve people should be happy and never fear a hugher authority or a "system". Dystopian societies are exciting to read about but to really think deeply and complexly about them is horrifying.
