Answer:

C. Sound waves echo off the smooth walls of a large auditorium.

Explanation:

Echo provides an evidence out of many that matter can reflect waves.

Echo is produced when sound waves bounds off the surface of a resistant body that does not allow it to transmit.

Reflection occurs when waves changes direction when they come in contact with another body. Auditoriums are made sound proof to curtail the effect of sound waves echoing.

It is a clear proof that matter can reflect waves.

Are genes a segment of DNA containing a set of instructions for making a protein ?

brilliants [131]

Answer: The given statement is True.

Gene can be described as the segment of DNA ( deoxyribonucleic acid), which codes for a particular protein. The protein thus formed, corresponds to a specific trait ( such as skin color, hair color, color of eye) of the individual organism.

They possess set of instructions for making a protein in the form of nucleotide sequences. Gene undergo transcription to form mRNA ( messenger RNA), which is then converted into particular protein through translation.

Genes are inherited from parents by their offspring and in this way specific traits are inherited by offspring from their parents.

Thus, given statement in the question is correct.

What sets of instructions in each human cell that determine inherited traits called?

larisa [96]

Answer:

Genes carry the information that determines your traits (say: trates), which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes.

When our bodies overcome the offensive tactics of a particular microorganism, this is referred to as? a) therapy. b) colonizatio

ikadub [295]

When our bodies overcome the offensive tactics of a particular microorganism, this is referred to as Resistance.

The body's defense against infection is provided by the immune system, a complex network of organs, cells, and proteins that also safeguards the body's own cells.

Our immune system remembers every germ (microbe) that the immune system has ever eliminated, allowing it to promptly identify and eliminate the microbe if it re-enters the body.

The body contains a number of additional mechanisms in addition to the immune system for defending itself against microorganisms, such as:

The skin acts as a waterproof barrier and secretes oil that has antibacterial qualities.

Lungs: Phlegm (mucous) in the lungs collects foreign particles, and tiny hairs (cilia) waft the phlegm upward so that it can be expelled through coughing.

digestive tract: Most germs can be killed by stomach acid and the mucous lining, which contains antibodies.

Added defenses include the anti-bacterial enzymes found in body fluids like skin oil, saliva, and tears, which can lower the chance of infection. Constant bowel and urinary tract flushing are also beneficial.
