Practice DAY-2

Front

Inherited trait that helps an organism survive is a(n) __________.

Back

Adaptation

Front

The process by which organisms better adapted to their environment tend to survive and produce more offspring is called __________.

Back

Natural Selection

Front

What is the mRNA molecule transcribed from the DNA template TGGCAAGTACGT?

Back

ACCGUUCATGCA

Front

Two types of walking stick insects are found in the same habitat. One has a long white stripe, and the other is entirely green. What explains their coexistence?

Back

The two varieties are adapted to different plant types, which allows them to maintain their numbers.

Front

Transcribe the DNA sequence TAC - TTA - CGA.

Back

AUG - AAU - GCU

Front

What is the definition of adaptation in biology?

Back

A trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What is the significance of natural selection in evolution?

Back

It is the mechanism by which evolution occurs, favoring traits that improve survival and reproduction.

Front

Define mRNA and its role in protein synthesis.

Back

mRNA (messenger RNA) carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is human-directed breeding for desired traits, while natural selection is the process by which traits that enhance survival are favored by the environment.

Front

Explain the concept of mutation in genetics.

Back

A mutation is a change in the DNA sequence that can lead to new traits in an organism.
