Explanation:
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.

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.

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

What is the function of tRNA?
catalyze the assembly of amino acids into a protein
carry genetic instructions for building a protein
bring an amino acid to the ribosome
Answer:
C bring an amino acid to the ribosome
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.

A. Ejaculatory duct
B. Vas deferens
C. Urethra
D. Seminiferous tubules
Answer:
C. Urethra
Explanation:
Sperm goes from the epididymis to the vas deferens. The vas deferens in each testis connects to the ejaculatory duct, that then connects to the urethra where the sperm can be ejected.
Hope this helps
Sperm go after leaving the ejaculatory duct through urethra. Therefore, the correct statement is option C.
What is urethra?Sperm travel through the urethra, which is a tube that connects the bladder to the outside of the body, after leaving the ejaculatory duct. During ejaculation, semen containing sperm is propelled through the urethra and out of the body.
The urethra is a conduit for both urine and semen. The urethra is a piece of both the urinary and conceptive frameworks in guys. The sperm travels through the urethra, which is a tube that connects the bladder to the tip of the male reproductive organ after leaving the ejaculatory duct.
The urethra serves a double capability in guys as it completes pee and semen of the body. Semen is produced by the bulbourethral, seminal, and prostate glands. During ejaculation, the sperm and semen mix in the ejaculatory duct before being released through the urethra.
Therefore, sperm go after leaving the ejaculatory duct through urethra.

What condition must be true if a substance enters the cell by active transport
For a substance which enters the cell by active transport, it should have a concentration gradient, energy, and transport proteins.
What is active transport?It is a process through which molecules move from a region of higher concentration to a region of lower concentration.
The following conditions must be true for active transport:
Concentration gradient-The concentration of substance must be higher outside the cell than inside the cell.Energy-Active transport requires energy in the form of ATP.Transport proteins- It allows specific transport proteins such as pumps to facilitate movement of substance across the cell membrane.Overall, active transport allows cells to bring in substances that they need even if the concentration of those substances is low outside the cell.
