Whiskers and beaks are two examples of _____. electroreceptors mechanoreceptors olfactory receptors photoreceptors
Whiskers and beaks are two examples of olfactory receptors. An olfactory receptor is a smell receptor that contains a protein capable of binding odor molecules that plays the central role of smell.
Answer:
its mechanoreceptors
Explanation:
mechanoreceptors react to pressure and distortion.
Answer:2p→1s
Explanation:
Frequency is inversely proportional to wavelength. The higher the frequency, the shorter that wavelength. The smaller the frequency the longer the wavelength. The frequency of light associated with 2p→1s is less than the frequency of light associated with 3p→1s since the latter represents transition from a much higher energy level. It follows that the wavelength associated with the former will be longer since its frequency is lesser. This deduction follows from our argument about the inverse relationship between frequency and wavelength.
b. Formality
c. Density
d. Molality
e. Normality
by a lowercase letter. This tells you the types of elements in the compound.
Answer:
Elements
Explanation:
The elements which are represented by a single uppercase letter, or represented by an uppercase letter followed by a lowercase letter. This tells you the types of elements in the compound.
Elements are one of the simplest chemical substances that cannot be decomposed in a chemical reaction or by any chemical means. They are made up of small indivisible particles called atoms, all having the same number of protons.
Chemical symbols which can be single uppercase or one uppercase followed by a lowercase letter, are used in Chemistry to represent elements. They are used in the composition of compounds. For example, 'H' for Hydrogen and 'Ca' for Calcium.
In Chemistry, elements are represented by one or two letters. The first letter is always uppercase and the second letter, if present, is lowercase. These are known as chemical symbols and they correspond to the elements in the Periodic Table. For instance, the symbol for Hydrogen is H, and for Calcium it's Ca. These symbols are used to denote elements in chemical compounds. For example, water (H2O) is a compound consisting of Hydrogen and Oxygen.

A. Some ice cubes are floating in the tea
B. The sugar crystals are no longer visible in the tea
C. The mixture looks the same throughout
D. Some water droplets form on the outside of the glass
The subject is science
Answer:
The correct option is;
A. Some ice cubes are floating in the tea
Explanation:
A heterogenous mixture is one that is made up of more than one clearly identifiable phase of matter (such as solid and liquid, liquid and gas, gas and solid, or solid, liquid and gas combined) and therefore having non-uniform composition, which varies from one section to another within the mixture.
Ice cubes which are solids being observable on the surface of the mixture provides clue that the student has made an heterogenous mixture.
Answer : The concentration in mol/L is
Explanation : Given,
Moles =
Volume of solution = 500 mL
Formula used :
Now put all the given values in this formula, we get:
Therefore, the concentration in mol/L is
