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.
Answer:
She is most likely studying cell membranes

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.

In an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. He studies two set of people—those who exercise every day for an hour and those who don’t exercise at all.
............................ In this case, the statement that people who exercise for an hoour may have lower cholesterol level is HYPOTHESIS. ....................... The cholesterol level would be the DEPENDENT VARIABLE.
An hypothesis refer to a proposed statement based on prior knowledge, which is used as a starting point in scientific experimentation.
In scientific experiments, there are always two variables, independent and the dependent variable. The independent variable is the variable that is changed or controlled in a scientific experiment in order to determine its effects on the dependent variable.
