<span>Almost all female progeny show the cleft chin trait so the percent would be 100%. This trait is normal called as dimples on the cheek. When you have cleft chin, it is quite possible that they have two dominant alleles or sometimes one dominant and one recessive allele.</span>
I believe the correct statement is that Water absorbs heat when it changes to vapor, helping to keep animals cool through perspiration. Water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to gas at constant temperature. In humans and other organisms, the evaporation of sweat, which is 90% water, cools the body to maintain a steady temperature.
Answer:
e, both A and C
Explanation:
The lytic life cycle ends when the virus load is expelled from the host cell. But, to be released, the virus have to escape from the host cell's plastic membrane, usually by changing the osmotic change, and making it explode.
This releases the viruses into the extracellular matrix, allowing them to infect other tissue cells.
Half life formula
The number of unstable nuclei remaining after time t can be determined according to this equation:
N(t) = N(0) * 0.5^(t/T)
where:
N(t) is the remaining quantity of a substance after time t has elapsed.
N(0) is the initial quantity of this substance.
T is the half-life.
It is also possible to determine the remaining quantity of a substance using a few other parameters:
N(t) = N(0) * e^(-t/τ)
N(t) = N(0) * e^(-λt)
τ is the mean lifetime - the average amount of time a nucleus remains intact.
λ is the decay constant (rate of decay).
All three of the parameters characterizing a substance's radioactivity are related in the following way:
T = ln(2)/λ = ln(2)*τ
How to calculate the half life
Determine the initial amount of a substance. For example, N(0) = 2.5 kg.
Determine the final amount of a substance - for instance, N(t) = 2.1 kg.
Measure how long it took for that amount of material to decay. In our experiment, we observed that it took 5 minutes.
Input these values into our half life calculator. It will compute a result for you instantaneously - in this case, the half life is equal to 19.88 minutes.
If you are not certain that our calculator returned the correct result, you can always check it using the half life formula.
