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

<h3>What is a quaternary structure?</h3>

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.

<h3>What do you mean by Proteins?</h3>

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.

5 factors that affect weather: geographic location/latitude altitude/height above sea level, ocean currents/large lakes, winds,t
Igoryamba

The statement is - True.

The five main factors that determine the weather at a certain place are the:

- geographic location/latitude

It determines the amount of sunlight, as well as the concentration of sun rays, which directly influences the temperature.

- altitude/height above sea level

The lower the place the warmer it is, the higher the place the colder it is, it is a simple rule that applies for all places on the planet, compared with places in their surroundings.

- ocean currents/large lakes

The ocean currents can bring cold and dry or warm and wet air masses, depending on what kind of an ocean current it is. The water also contributes to a more stable weather, with more moderate temperatures because of the thermal properties of the water to cool of and warm up slower than the land.

- winds

The air masses can bring cold and dry or warm and wet weather, so they influence the temperature and precipitation of a place.

- topography

Determines how much a place is exposed to the sunlight and the movement of the air masses.

11111nata11111 [884]

Answer:

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

Hope this helped!
