Biology
1 answer:
stepan [7]3 years ago
3 0

Answer:

Mass Number and Atomic Number

Explanation:

Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.

A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y
antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:  

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:  

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.

Kisachek [45]

Answer:

Part A It is associated with peroxisomes and mitochondria.

Part B. It is associated with smooth endoplasmatic reticulum.

Explanation:

The oxidation of long chain fatty acids are produced at the beginning in the mitochondria, it is called B oxidation because there is a carbon in this position that in this process is going to be oxidized to a carbonyl group. The very long fatty acid chains are also oxidized in the peroxisomes.

The cholesterol biosynthesis is made inside the hepatic cells, in the endoplasmatic reticulum. Is a process that starts with acetyl Coenzime A that was oxidized in the mitochondria. This process is regulated by the intake of cholesterol from the diet.

Hope this info is useful.

In the capillaries, hydrostatic pressure (hp) is exerted by __________. view available hint(s) in the capillaries, hydrostatic p
pochemuha
Blood pressure

This is indicated in Starling's Hypothesis in which there is fluid movement due to filtration across the wall of capillary. This is dependent between hydrostatic pressure gradient and oncotic pressure across the capillary. The balance of these forces allow the net driving pressure for filtration. The net fluid influc is proportional to this net driving pressure. The leakage of proteins across the capillary membrane has important effects and has corresponding cause in the balance of forces.
