When performing scientific research, one must always avoid using personal biases so that there are no errors or interruptions. Hope this helps you.
Answer:
When Darwin formulated the theory of evolution through ____THE PINZONES________ ____________, he used changes he saw in the __________ OTHER SPECIES OF THE GALAPAGOS ISLANDS______________ to support his assertions. However, there are other pieces of evidence that demonstrate the occurrence of evolution in living things.
Explanation:
Charles Darwin analyzed the evolution of life or living beings through a species of birds that are called finches, also to reinforce this theory he analyzed other species on the Galapagos Island where these finches were, and noted that the turtles were from larger and the rest of the species also presented some differences, this is how their theory reinforces and drives it, indicating that the one that survives is the most suitable for that particular environment.
Answer:
We have two alleles, XA and Xa and the genotypic frequencies are given by p^2 + 2pq + q^2 = 1
In this equation XA is p and Xa is q. Therefore p^2 is the frequency of the genotype XAXA, etc.
For X-linked conditions, females have 2 alleles for the gene, but males only have one. So calculate the genotypic frequencies for males and females separately. Since the population is in Hardy-Weinberg equilibruim, the allelic frequency is the same for both sexes.
Since males only have one X chromosome, the frequency of X linked in male is equal to the allelic frequency. So frequency just equals 1/5000 or 0.0002
so q^2 = q for males in X linked
So q = 0.0002
for females, she would need to have both alleles, so her frequency of the homozygous genotype is q^2 = 0.0002^2 = 0.00000004
number of affected females would be q^2 x number of females in the population
so 0.00000004 x 160 mil = 6.4 females would have hemophilia.
Explanation:
Answer:
The chemical inhibits the binding of ligand with receptor.
Explanation:
Channel linked receptor are activated by the binding of the ligand with the receptor. Ligand gated ion channel are also known as the channel linked receptors.
The chemical used by the cell biologist has blocked one of the channel-linked receptor in a lab rat's liver tissue. The chemical must inhibits the receptor binding with its ligand.
