The picture above is of a plant's xylem and phloem. the xylem transports water from the roots to the leaves. the phloem transports food from the leaves made by photosynthesis to the rest of the plant. this vascular bundle (xylem and phloem) is similar to a human tissues. place the xylem and phloem with the human tissues that is most similar to it. the statement is to be read as ": " reads "is to" and ": : " reads "as". ex: kitten: cat : : puppy: dog can be read as "kitten is to cat as puppy is to dog".

Sugars move down to the roots and water-nutrients move up to leaves Xylem and phloem make up the big transportation system of vascular plants. As you get bigger, it is more difficult to transport nutrients,water, and sugars around your body. You have a circulatory system if you want to keep growing. Asplants evolved to ...

Explanation:

Let p be the frequency of LM Allele and q is the frequency of LN Allele

Two alleles are Co-dominant

and p=0.8

so q=1-p=1-0.8=0.2

and inbreeding coefficient or F=0.05 (it is the degree to which two alleles are more likely to be homozygous rather than heterozygous)

The frequency of Homozygotes LMLM = (1-F) p2 +Fp

=p2-Fp2+Fp

=p2+Fp(1-p)

=p2+Fpq

Therefore, The frequency of Homozygotes LMLM in the Eskimo population will be

f(LMLM)= (0.8)2 + 0.05 (0.8) (0.2)

=0.648

Similarly The frequency of Homozygotes LNLN = q2+Fpq

or f(LNLN) = (0.2)2+0.05 (0.8) (0.2)

=0.048

And The frequency of Heterozygotes LMLN =2pq (1-F)

f(LMLN) = 2 (0.8)(0.2) (1-0.05)

=0.304

The expected frequencies of different blood types are

f(MM)=0.648, f(MN)=0.304, f(NN)=0.048
