An example of an external stimulus is a decrease in oxygen levels in the blood during exercise.

Option C

<h3>What is stimulus?</h3>

A stimulus is defined as a thing or sensation that causes a specific reaction in an organ or tissue of a living organism

There are two types of stimuli:

Internal stimulus
External stimulus

The functional structure of a protein is its _________________ structure, which is ultimately determined by the ________________

Dmitriy789 [7]

Answer:

Explanation:

The tertiary structure of proteins is related to the interactions between the amino acids of the primary structure. Thus, these interactions give it a specific three-dimensional configuration which is very sensitive to functionality.

For example, allosteric inhibitions are related to this concept. When the inhibitor changes the tertiary structure of the protein it loses all activity and for the catalysis of the reaction.

Thus, the primary structure (which is related to the specific sequence of amino acids) will determine the tertiary structure since the chain folds will be a consequence of intra-amino acid interactions.

A 2.04 g lead weight, initially at 10.8 oC, is submerged in 7.62 g of water at 52.3 oC in an insulated container. clear = 0.128

alisha [4.7K]

Answer: The final temperature of both the weight and the water at thermal equilibrium is $50.26^{o}C$ .

Explanation:

The given data is as follows.

mass = 7.62 g, $T_{2} = 10.8^{o}C$

Let us assume that T be the final temperature. Therefore, heat lost by water is calculated as follows.

q = $mC \times \Delta T$

= $7.62 g \times 4.184 J/^{o}C \times (52.3 - T)$

Now, heat gained by lead will be calculated as follows.

q = $mC \times \text{Temperature change of lead}$

= $2.04 \times 0.128 \times (T - 11.0)$

According to the given situation,

Heat lost = Heat gained

$7.62 g \times 4.184 J/^{o}C \times (52.3 - T)$ = $2.04 \times 0.128 \times (T - 11.0)$

T = $50.26^{o}C$

Thus, we can conclude that the final temperature of both the weight and the water at thermal equilibrium is $50.26^{o}C$ .

Which processes result in the realese of carbon

Zanzabum

Answer:

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combines with oxygen in the air to form carbon dioxide and water vapor.
