Answer:
B. Hearing.
D. Balance.
Explanation:
The ears are organs that provide two main functions: hearing and balance that depend on specialized receptors called hair cells.
Element describes a pure substance that is made up of only one type of atom. Elements cannot be broken down into more simpler substances. There have been 118 elements discovered by scientists so far.
Answer:
Structure of bacteria:
Bacteria is a unicellular and prokaryotic organism i. e. made of one cell and no membrane is present around the nucleus. They are found in many shapes such as rods, spherical and cylindrical etc.
Reproduction in bacteria:
In bacteria asexual reproduction occurs such as binary fission. In binary fission, the body of organisms is divided into two equal parts and each part becomes a new organism.
Infection caused by bacteria:
Bacteria cause infection by entering the host cell and starts reproducing and after that they attack on the neighbor cells.
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Answer:
Proteins would be formed incorrectly
Explanation:
This is because the mRNA codon sequence would be altered, which is responsible for protein formation.
