Answer:

Fossil B belongs to the same period as the trilobite.

Explanation:

If we look at the image and the organism key, we can see that fossil B and the trilobite are in the same layer of the rock. This means that they were from the same time period. If something is found at a deeper layer in the rock (or the bottom of the chart) it means it is older than something found above it. Likewise, if something is on the outside layer of the rock (or the top of the chart) it is younger than something found below it.

<h3>How does respiratory rate affect pH?</h3>

When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.

With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.

What are the two factors that affect the friction between two surfaces

Answer:

The two factors are:

When the surface is partially not smooth or totally rough, a greater force is been needed to move one surface past the other.

The weight of the can also significantly be a key factor. This is where the need to friction reduction come to play a role; and need for friction reducers like lubricant, rollers etc helps.
