Answer:

99 to 138.6 bpm

Explanation:

The heart rate of an individual is a measure of how many times the heart beats in a given time, usually measured in beats per minute (bpm).

Resting heart rate is the number of beats per minute when an individual at rest. Generally, it can be understood that the lower the resting heart rate, the more physically fit an individual is.

The maximum heart rate for an individual is 220 minus their age. The target heart rate for moderate physical activity is 50-70% of the maximum heart rate and for vigorous physical activity it is 70-85% of the maximum heart rate.

Based on Holly's age, her maximum heart rate is 220 - 22 = 198 bpm

Her heart rate zone for moderate physical activity is 50-70% of 198 bpm: 99 to 138.6 bpm

Her heart rate zone for vigorous physical activity is 70-85% of 198 bpm: 138.6 to 168.3 bpm

The DNA in a cell's nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well
spayn [35]

Answer:

PFK (protein): cytoplasm only (targeting pathway)

Insulin (protein): ER->Golgi->outside cell

Explanation:

Translation can be described as the mechanism by which a protein is produced through a mRNA.

If a particular protein is to function inside the same cell, then it doesn't need to get any modification so that it can travel outside the cell. Such type of proteins are translated on free cytoplasmic ribosomes and are released directly into the cytoplasm to perform their function. For example, PFK protein.

If a protein has to function outside the cell where it is produced, then it has to be modified. Such type or proteins are translated on the rough ER.  They are then modified in the Golgi complex and then transported outside the cell to the area where they have to function. For example, insulin.

The following facts are true about resource A
IceJOKER [234]

Answer:

Option D, renewable resource

Explanation:

A renewable resource is the resource  which can be replenished after every use. Or in general the time taken by it to replenish must be small. For instance, fossil fuels too are renewable but the time taken by them to renew is too high and hence they are also considered as non-renewable.  

Also renewable resources can be used again and again.  

Hence, option D is correct

If an object has a volume of 32 ml and the mass of 146g what is the density?
True [87]
The density uses this equation :

D = m ÷ v

D (Density)
M (Mass)
V (Volume)

⓵
Replace your numbers in the equation :

D = m ÷ v

D = 146 ÷ 32

D = 4,5625

D ⋍ 4,56
