Answer: b. Primordial soup origin hypothesis
Explanation:
The primordial soup hypothesis is the basis of the origin of life on earth. Life originated in the ocean water as a result of the combination of chemicals from the atmosphere and energy from the sun to make up the amino acids. The amino acids are the building blocks of proteins. The protein was the basis of the development of life forms and their evolution on planet earth. The chemical evolution supposed to occur at least 3.8 billion years ago.
Answer:
C. a sequence complementary to the promoter of the operon
Explanation:
MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are two major classes of small non-coding RNAs (sncRNAs) that function to control gene expression by binding to complementary RNA transcripts. Antisense oligonucleotides exploit this natural ability of the sncRNAs to regulate target gene expression.
An operon is a procaryotic single-strand DNA that contains a group of genes modulated by one single promoter, which are transcribed together to produce a single polycistronic messenger RNA (mRNA). In this example, the antisense complementary oligonucleotide will bind to the mRNA to modulate its transcription and, consequently, also protein synthesis.
one of the most important rain forest predators, attacking a wide range of different primates, is the monkey-eating eagle. we know this because all forest primates have an identical alarm call that means, essentially, "Eagle!"
<h3>What are primates?</h3>
Primates are those forest animals that has highly developed brain and backbone.
Some of them are predators while others are source of food for predators known as preys.
Example of such predators are the monkey eating eagles which are capable of hunting monkeys as their preys.
