Answer:
Transport O₂ and nutrients throughout the body
Remove waste products found within the body
Explanation:
The circulatory system performs the function of transporting oxygen and nutrients to the cells. It also helps in removing the wastes from these cells. The circulatory system involves blood, blood vessels, arteries, veins, and capillaries. From the lungs, the oxygen is carried to all parts of the cells. The waste product, carbon dioxide, is carried to the lungs. The nutrients are carried from the small intestine and delivered to all the cells of the body.

A heterozygous organism has
1.three different alleles for a trait
2. Two identical alleles for a trait
3. Only one allele for a trait
4. Two different alleles for a trait
I'm completely sure your answer would be D.
It has two different alleles for a trait!
An organism that is heterozygous has two different alleles for the same trait. Therefore, the correct option is B.
Alleles are genetic variants that affect the way a trait is expressed in different ways. During sexual reproduction an organism receives one allele from each parent. If these alleles disagree, the organism is said to be heterozygous for that trait. Two different alleles enable genetic diversity and the possibility of different phenotypic outcomes. A dominant allele may be expressed as a result of heterozygosity, while the effect of a recessive allele may be obscured. This genetic diversity is important for evolution because it gives rise to natural selection and the ability to adapt to changing conditions.
Therefore, the correct option is B.

A biologist is studying a structure that is made up of two layers of phospholipids. What is she most likely studying?
Answer:
Phospholipid Bilayer
Explanation:
The cellular phospholipid bilayer has 2 layers of phospholipids(obviously), but keep in mind that the heads of said phospholipids are hydrophillic(loving water) and the tails are hydrophobic(hating water). This makes the 2 layers line up with heads facing away from each other and tails facing each other. This is so the bilayer can exist in the aqueous enviorment outside the cell as a barrier and inside the aqueous enviorment of the cell to transport materials in and out of the cell.
