Which of the following is an example of commensalism?
Answers
An example of commensalism is tick on a deer. Therefore, option A is correct.
What is commensalism ?
Another sort of symbiotic interaction is commensalism, in which one organism benefits and the other does not in any way suffer. Golden jackals will pursue tigers as they hunt in order to consume the tigers' leftovers.
The term "commensalism" is derived from the word "commensal," which in human social interaction refers to "eating at the same table," and which itself is derived through French from the Medieval Latin term "commensalis," which refers to "sharing a table," from the prefix com-, which means "together," and mensa, which refers to "table" or "meal."
The simplest definition of commensalism is that it is a form of symbiosis in which one organism gains while the other neither gains nor suffers harm. The three primary forms of commensalism are phoresy, metabiosis, and inquilinism.
Thus, option A is correct.

The following conclusion can be made if an ion of an element is smaller than an atom of the same element:
Further explanation:
Ions are the entities with a net electric charge, be it positive or negative. Since positive and negative charges can be present on the ions, ions are of two types-positively charged and negatively charged ions. The ions formed by loss of electrons develop a positive charge and are called cations. But the ions produced by the gain of electrons acquire a negative charge and are called anions.
Since cations are positively charged ions, these have fewer electrons as compared to the corresponding neutral atom. So these ions experience stronger forces of attraction with the atomic nucleus and are smaller in size in size than the parent atom.
Anions are formed by the addition of electrons to the neutral atom. It has more electrons than the parent atom so it feels electron-electron repulsion due to which its size becomes larger than the parent atom.
So cations are smaller than the parent atom of the same element whereas anions are larger than the parent atoms. Therefore if an ion is smaller than the atom, it is positively charged due to the presence of fewer electrons than the parent atom.

then, you convert from 12.9 Liters to moles.
1 mole = 22.4 Liters of gas.
x moles = 12.9 liters
So, 22.4x = 12.9, which means that x = 12.9/22.4, and you get about 0.6, then you divide by 3 because you have 3 Oxygen, and you get about 0.2.
So, 0.2 moles of ethylene C2H4 can react with 12.9 liters of Oxygen Gas.
Hope this Helps :)

This is some kind of is the electrostatic attraction between polar molecules that occurs when a hydrogen (H) atom bound to a highly electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F)... see image below! ;-)
Final answer:
The intermolecular forces that exist between molecules of NH3, H2O, and HF are hydrogen bonding, dipole-dipole interactions, and London dispersion forces.
Explanation:
The intermolecular forces that exist between molecules of NH3, H2O, and HF are called hydrogen bonding, dipole-dipole interactions, and London dispersion forces. Hydrogen bonding occurs between a hydrogen atom bonded to a highly electronegative atom (such as O, N, or F) and a lone pair of electrons on a nearby molecule. Dipole-dipole interactions occur between molecules with permanent dipole moments, while London dispersion forces occur due to the temporary formation of induced dipoles in adjacent molecules.

The answer to the riddle Maggie is solving is 6
To determine the answer to the riddle Maggie is solving,
We will subtract the number of valence electrons in halogens by the number of valence electrons in alkali metals.
First, let us define what is meant by valence electrons
Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus.
Now, we will the determine the respective number of valence electrons in halogens as well as the number of valence electrons in alkali metals.
For Halogens
Halogens are the group 17 (group 7A) elements in the periodic table. Examples are Fluorine, Chlorine, Bromine etc.
Halogens have 7 electrons in their outermost shell
For Alkali metals
Alkali metals are the group 1 metals. Examples are Lithium, Sodium, Potassium etc.
Alkali metals have 1 electron in their outermost shell
Now, for the answer to the riddle,
Answer to the riddle = Number of valence electrons in halogens - Number of valence electrons in Alkali metals
\
Answer to the riddle = 7 - 1
∴ Answer to the riddle = 6
Hence, the answer to the riddle Maggie is solving is 6
