Student compares two different proteins. the student notices that the primary structures differ in both the number of amino acid
tamaranim1 [39]
Each protein has its unique sequence and number of amino acids. This determines their 3-D structure as well. The properties of the protein are also attributed to the unique sequence and number of amino acids present in it. Different sequence and number denote that the two proteins are different, and have different structure and properties.

MatroZZZ [7]
There are choices for this question namely:

a. cementation of clastic sediments and precipitates from seawater 
<span>b. compaction and recrystallization of volcanic material </span>
<span>c. regional metamorphism of sedimentary and igneous rocks </span>
<span>d. contact metamorphism of unconsolidated gravel 
</span>
The correct answer is that the bedrock of the Adirondock mountains is formed mainly by regional metamorphism of sedimentary and igneous rocks. The geology of the Adirondock mountains formed around 5 million years ago with rocks  over 1000 million years old. At this very ancient age, the sedimentary and igneous rocks in the Adirondock mountains have undergone extensive heat and pressure hence regional metamorphism of the existing sedimentary and igneous rocks.

marissa [1.9K]

Answer:

Gravitational equilibrium helps maintain the environment in the Sun's core that is conducive to nuclear fusion. The Sun's gravitational equilibrium balances the gravity pulling inward and the pressure pushing outward. It keeps the Sun's size, denseness, and hotness stable, thus making nuclear fusion possible.

What are the body’s three defenses? How do they differ from each other.
Artemon [7]

Answer:

- Physical and chemical barriers

- non-specific innate responses

- specific adaptive responses

<u>The differences are...</u>

The first barrier is the physical and chemical barrier. It is the first line of defense when in contact with outside sources, this can be through the skin, earwax, nose-hair, etc.

The second barrier, the non-specific innate response, is after these outside sources have somehow managed to pass through the first barrier. They come into contact with cells and enzymes that help to defeat them.

The third barrier, the specific adaptive response, is the body's way of dealing with pathogens that the body has encountered before. (B cells activate)
