Explanation

 Structures that have similar functions but evolved independently from different ancestral origins are called analogous structures. 

Explanation

The roundworm, also known as a nematode, is an invertebrate that possesses a pseudocoelom. 

Explanation

• Replication is the process by which a cell makes an exact copy of its DNA before cell division, ensuring that the new cell receives a complete set of genetic instructions.
• This process is crucial for the transmission of genetic information from one generation of cells to the next.

Explanation

Gene cloning creates multiple identical copies of a specific gene or DNA sequence.

It using techniques like PCR or DNA cloning vectors.

To amplify and study specific genes or genetic elements.

Explanation

A single strand of nucleic acid tagged with a radioactive molecule is called a probe.

These probes are often used in molecular biology techniques to detect specific DNA or RNA sequences. 

Explanation

Triploblastic animals have three germ layers (ectoderm, mesoderm, endoderm).

Roundworms (Nematodes) are triploblastic.

Explanation

On a DNA strand, nucleotides are linked together by phosphodiester bonds.

These bonds connect the 5' carbon of one nucleotide's sugar to the 3' carbon of the next nucleotide's sugar, forming a chain. 

Explanation

The smallest unit that can evolve is a population. 

Evolution refers to changes in the allele frequencies within a population over time

Since individual organisms cannot evolve on their own,

it's the group of individuals (the population) that experiences these changes. 

Explanation

 An anticodon is located on tRNA (transfer RNA).

The anticodon is a sequence of three nucleotides that recognizes and binds to a specific codon on mRNA during protein synthesis. 

Explanation

A nucleoside is composed of a Base + Sugar. 

A nucleoside is a molecule made up of a nitrogenous base (like adenine, guanine, cytosine, or thymine) 

Attached to a five-carbon sugar (ribose or deoxyribose).

It lacks the phosphate group that is found in a nucleotide.
