When two protein chains combine to form an active protein, the structural level is quaternary.

The quaternary and tertiary structure of a protein is the tridimensional shape of the protein, which involves protein domains.

The quaternary protein structure refers to the different arrangements generated by different protein subunits.

The primary structure of a protein involves its amino acid sequence, whereas the second structure involves protein chains.

When two protein chains combine to form an active protein, the structural level is the quaternary arrangement.

Proteins may be defined as naturally emerging, extremely intricate substances that comprise amino acid residues joined by peptide bonds.

The Quaternary structure of a protein is very complex and 3-dimensional as compared to other protein structures which involve numerous motifs and domains.

Therefore, when two protein chains combine to form an active protein, the structural level is the quaternary arrangement.

Natural selection causes evolution in the population of pea plants and leads to an increase in favorable adaptations.

Explanation:

The flowers will evolve to keep that purple trait in order to continue their population growth, hence why it is not individual evolution but as a population. Also since the purple color is a favorable trait it will lead to an increase in favorable adaptations and will decrease variation.

How are animals similar? All animals are made of many cells. Most animals can move on their own. Like all living things, animals grow, change, reproduce, and respond to their environment.

Animals are made up of several cells. Most animals have independent movement. Animals develop, transform, reproduce, and react to their surroundings like all other living creatures do.

Any eukaryotic multicellular organism of the biological kingdom Animalia is referred to as an animal.

The majority of creatures in this kingdom lack a cell wall, are heterotrophic, motile, have specialised sensory organs, and originate from blastulae during embryonic development.

According to some, the fundamental distinctions between humans and other animal species are our capacity for complex reasoning, our use of complex language.

Also, the capacity for problem-solving, and the capacity for introspection (this means describing your own thoughts and feelings).

Multiple cells make up an animal. The majority of animals can move on their own. Like all other living things, animals grow, change, reproduce, and respond to their surroundings.

Deforestation increases the risk of floods in an area tree roots improve soil water retention.

When deforestation takes place, the top layer of soil can be dislodged – this is also known as soil erosion.

When the top layer of soil is unstable, it is unable to retain any of the water that falls on it, resulting in increased surface run-off, which, in turn, increases the risk of flooding.

Answer:

First, you must know what the stop codons are: UAA, UAG, and UGA

Whenever this sequence is read, it signals for an end in transcription and amino acids will stop being formed

Thus, 5′−GGCCCUUUUAGGGCCUUUUU−3′ contains a cue for transcription termination as it will stop after the codon "UAG"

Explanation:

Those mRNA sequences that consist of the stop codons like UAA, UGA, and UAG would form a structure that is a cue for transcription termination of some genes.

Transcription may be defined as the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).

Stop codons are responsible for the termination of transcription of almost all the genes. They are necessary for inhibiting the excessive expression of some genes.

Therefore, those mRNA sequences that consist of the stop codons like UAA, UGA, and UAG would form a structure that is a cue for transcription termination of some genes.

Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

Explanation:

The correct statement is C. They demonstrate how different species differ and which creature created the structure first. Anatomical characteristics observed in several species that have a common ancestor include what are known as homologous structures.

Although these structures may have diverse purposes in many creatures, their similarities suggest that they had an ancestor.

The anatomical characteristics of several creatures may be compared to find homologous structures and deduce evolutionary links.

Because diverse kinds of creatures have homologous features, it is likely that these qualities were passed down from a common ancestor.

Similarity levels and common anatomical patterns might shed light on a species' evolutionary path.
