what do you think the answer is?

Answers

By definition, communicable diseases are diseases that can be passed from one person to another. Also, not all communicable diseases are caused by bacteria only nor virus only. So therefore, the answer would be option A. The statement that BEST describes common communicable diseases is this: Most communicable diseases are either bacterial or viral and infect the respiratory tract. Hope this answer helps.

Most communicable diseases are either bacterial or viral and infect the respiratory tract.

Communicable, or infectious diseases, are generated by microorganisms such as parasites, fungi, bacteria, and viruses, which can be spread, directly or indirectly, from one person to person.

A majority of upper respiratory diseases are due to self-limited viral epidemics. Occasionally, bacterial germs may produce upper respiratory infections. Most often, upper respiratory virus is communicable and can spread from person to person by breathing respiratory droplets from coughing or sneezing.

True or False? As the energy is transferred from producers to consumers, energy is gained.

Answers

Answer:

False.

Explanation:

The food chain may be defined as the sequential tropic levels in which the organism eat other organisms and itself being eaten by other organism. Food chain do not exist in nature.

According to the 10% energy law, the energy is lost from one tropic level to the another tropic level. The 10% energy is available to the next tropic level and the remaining amount of energy is lost as heat. No energy gain occurs as the transfer of energy takes place from the producer to consumer.

Thus, the answer is false.
false because it's using energy to do the work. one way to gain energy is by making it. but yet again this is my thought but like i said it's false.
