Answer:Bacteria and Fungi both come under different categories. Bacteria is the prokaryotic cell while the fungi are Eukaryotic cells. On the other hand, fungi grow their own and are heterotrophs and hence depend on others for their food. ...

Hey bud, I saw this was your first question. You need to attach some files to your question in order for us to see it. You can do that by using the Paperclip shaped icon on the bottom when you are making a question.
Explanation:
Answer:
because the beaks are different and since they prefer other avaliable seeds.
because the population changes over time its called natural selection, in darwins drawings there were extremely different from eachother.
because when he drew normal finches and went to galapagos islands he saw that there were also finches but they looked completely different and he analyzed their beaks. there are animals who change over natural selection

Answer:
allelic frequency a = 30%
allelic frequency A = 70%
Explanation:
You are studying a population of sparrows in which the phenotype is determined by a single locus. Only two alleles for this locus are known for this population, which are distinguished by the codes 'A' and 'a'. The distribution of phenotypes in the population indicates that 49% of the population is homozygous 'AA', 42% is heterozygous and 9% 'aa' homozygous. How is the allele frequency for 'A' and 'a' determined based on these observations?
According to the case, the allelic frequency for A and a will be searched with the data:
homozygotes AA = 49%
heterozygotes Aa = 42%
homozygous aa = 9%
Frequency of homozygotes 'aa'
(q 2) = 9/100 = 0.09
we can obtain the allelic frequency of a through the following formula:
a (q) = √0.09
The result will be
= 0.3
we change to percentage
= 30%
we have the following formula
p + q = 1
to find the allele frequency A, represented by p
p = 1 - 0.3
we get the following result
p = 0.7
we change to percentage
= 70%
