Answer:
Main function of phloem Transportation of food particles.
Explanation:
Phloem is the living vascular tissue in plants. Phloem is also known as bast. Phloem is responsible for transporting food to parts of the plant where needed. It's mainly transport sugar sucrose which is made by photosynthesis. This transport process is called translocation. In trees the phloem is the innermost layer of the bark.
The answer is
fly #1: Genotype: XBY, phenotype: male with bar-shaped eyes
fly #2: Genotype: XbXb, phenotype: female with normal-shaped eyes
fly #3: Genotype: XBY, phenotype: male with bar-shaped eyes
fly #4: Genotype: XBXB, phenotype: female with bar-shaped eyes
Since there is difference in inheritance, bar-shaped eyes must be X-linked dominant trait.
XB - dominant allele on X chromosome for bar-shaped eyes
Xb - recessive allele on X chromosome for normal-shaped eyes.
Let's see:
<span>Male offspring from parents that contained only bar-shaped alleles will have bar eyes:
Father Mother
</span>Parents: XBY x XBXB
Male offspring: <span>XBY
fly#1: XBY
</span><span>Fly#1 is crossed with a normal-eyed female (fly#2) only the female offspring have bar-shaped eyes:
Father Mother
Parents: XBY x XbXb
Female offspring: XBXb
fly#2: XbXb
</span><span>If a normal-eyed (fly#3) is crossed with a bar-eyed female (fly#4), whose parents contained only bar-shaped alleles, all their offspring will have bar-shaped eyes.:
Father Mother
Parents: XbY x XBXB (since her parents were: XBY and XBXB)
Offspring: XBXb XBXb XBY XBY</span>
Answer:
to make life
Explanation:
nutrients are the thing in our body that fuel us and give us LIFE without nutrients we cant survive, so nutrients job is to make life
