Ozone is produced naturally in the stratosphere. But this "good" ozone is gradually being destroyed by man-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. These substances were formerly used and sometimes still are used in coolants, foaming agents, fire extinguishers, solvents, pesticides, and aerosol propellants. Once released into the air these ozone-depleting substances degrade very slowly. In fact, they can remain intact for years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun's UV rays and release chlorine and bromine molecules, which destroy the "good" ozone. Scientists estimate that one chlorine atom can destroy 100,000 "good" ozone molecules.
The statement 'plants have specialized tissues and organs and blue-green algae do not' identifies a characteristic that distinguishes algae from plants. They are different groups.
<h3>Planta and algae: similarities and differences</h3>
Plants and algae are autotrophic organisms that obtain their food by a process called photosynthesis.
Photosynthesis is a series of reactions by which plants and algae cells obtain simple carbohydrates by using the energy from the sun.
However, algae are unicellular organisms, whereas plants are multicellular organisms and are formed by tissues and organs.

Answer:
Is C
Explanation:
In translation, the cell uses the genetic information contained in mRNA to make the proteins that
carry out the cell’s work. The cell translates the code contained in the mRNA into a new
language, the language of proteins, based on amino acids. Other types of RNA, such as transfer
R
In this section, you will be introduced to the components involved in the process of protein
synthesis, called translation. This process requires a protein/RNA complex called the ribosome
Flaccid paralysis is a neurological condition characterized by weakness or paralysis and reduced muscle tone without other obvious cause
Option D. a & b a) endospore forming bacterium b) clostridium botulinum
A common cause of flaccid paralysis is anterior spinal artery syndrome, an occlusion of the anterior spinal artery. Obstruction can be caused by spinal cord trauma, cancer, arterial disease, or thrombosis.
Flaccid paralysis causes muscles to contract and go limp. lead to muscle weakness. Spastic paralysis affects tight, rigid muscles. Muscles may twitch or spasm uncontrollably.
Acute flaccid myelitis can be caused by infection with a type of virus known as an enterovirus. Respiratory illness and fever due to enteroviruses are especially common in children. most people recover.
