Answer:
Charge us
Sell the info
Explanation:
They can first charge individuals to use the services. For example, similar to 23andme or Ancestry, who provide a service of telling you interesting things related to your health or ethnicity.
They could also sell that data to pharmaceutical companies or other research groups who can use the DNA information for research. The more samples of DNA we have sequenced, the more information scientists have to work with and design drugs and more.
Answer:
The law of independent assortment states that the different genes get separated independently of each other and gets assorted into gametes to produce different combination of genes.
It was formulates by famous scientist G. Mendel based on his work on peas.
For example, in a traditional dihybrid cross of true breeding round and yellow seed plant with wrinkled and green seed plant, F2 generation show four different combinations of phenotype:
- round and yellow
- round and green
- wrinkled and yellow
- wrinkled and green
It shows that genes for round and yellow were independently inherited and genes for wrinkled and green were independently inherited. Else, new combinations could not be observed.
Homologous recombination is an event that takes place in prophase I during meiosis. The genetic material is exchanged between the non-sister chromtids of homologous chromosomes. It adds into the genetic variation within a population by producing more combination of genes in the gametes.
It does not violate the law of independent assortment as the genes were independently assorted. It only helps in producing more combinations of genes.
The correct answer is false, only one sperm usually reaches the egg for fertilization.
<span>Two haploid cells are </span>produced by any parent cell that undergoes mitosis, four haploid cells require other things as well.
Answer:
Answer: 7.949\ \text{days}7.949 days
Step-by-step explanation:
Given
The half-life of a sample is T_{\frac{1}{2}}=3.823\ \text{days}T
2
1 =3.823 days
Decay is given by
A=A_o2^{\dfrac{-t}{T_{\frac{1}{2}}}}A=A

−t
After 3 half-lives, one-eight of the sample is left
Insert the values
\begin{gathered}\Rightarrow \dfrac{A_o}{8}=A_oe^{\dfrac{-t}{T_{\frac{1}{2}}}}\\\\\Rightarrow e^{\dfrac{t}{T_{\frac{1}{2}}}}=8\\\\\text{Taking log both sides}\\\Rightarrow \dfrac{t}{T_{\frac{1}{2}}}=\ln 8\\\\\Rightarrow t=3.823\times \ln 8\\\\\Rightarrow t=7.944\ \text{days}\end{gathered}
⇒
