What characteristics make white dwarf stars different from main sequence stars?
Answer:
Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs. White dwarfs no longer burn fusion at their center, but they still radiate heat.
More than 90% of plants have mycorrhizal associations with fungi. How might this association have evolved (include mechanisms)
Answer:
It is a symbiotic relationship and it evolved because of the benefits both plants and fungi derive from the association.
Explanation:
Mycorrhizal association is a symbiotic association between fungi and plants where both of the benefits from the relationship. The fungi inhabit the root system of plants which increase the ability of the plant's root system to absorb water for it own use and the fungi benefited from it by carbohydrates from plants which is produced as a result of photosynthesis.

Question 28
A person who has PKU, a recessive genetic disorder,
А
inherited the allele for the trait from one parent.
B
inherited the allele for the trait from both parents.
С
is heterozygous for the trait.
ОО
D
will not pass the allele for the trait to his or her offspring.
Answer:
B
Explanation:
In order for one to have a recessive trait, both parents must carry the trait.
XX Xy= XX XX Xy Xy
Xy Xy= XX Xy Xy YY
XX XX= XX XX XX XX
yy yy= yy yy yy yy
Only the options in which both parents have the allele can pass it on. Only if there is no dominant allele will the trait be expressed, which can only be a yy recessive (since heterozygous would be dominant). Therefore, he will pass the allele on to his/her offspring.
A type of large mammal living in herds develops many adaptations over a
period of time. These include ability to drink a lot of water and go without
water for long periods of time and fur on the top of their body.
What can we say about the living conditions of these mammals?
Select one
They are grass eaters who must travel long distances to find food.
They are hunters that rely on group tactics to get their prey.
They live in a sunny environment where water is scarce.
They live in a cold environment with lots of trees but lite grass.

A classic example of osmosis in the classroom involves placing an egg in water or syrup. The egg first sits in vinegar until the shell is dissolved. Then, it is placed in a glass of either tap water or syrup. The mass of the egg is measured. The results are in the chart below. Use what you know about osmosis to explain why the egg increased in mass in the distilled water but decreased in mass in the corn syrup.
Answer:
Water is hypotonic compared to the inside of the egg; there are more solutes in the egg than in the water. Because water moves down its concentration gradient, it moves from the distilled water into the egg. It will continue to move in this direction until there is an equilibrium between the inside of the egg and the surrounding water. This increases the mass of the egg.
Corn syrup is hypertonic to the inside of the egg. Again, water moves down its concentration gradient from the inside of the egg to the solution. This will decrease the mass of the egg.
The reason solutes do not move, instead of water, in these situations is because the egg shell (assuming it is like a chicken egg) does not allow solutes to pass though it. Only water is able to move through the shell.

How do heterotrophs make energy? How do autotrophs make energy?
Answer:
Heterotrophs obtain energy by eating plants and animals. Plants are autotrophs, absorbing the sun's energy through photosynthesis and making glucose. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.

What foods below would test positive for starch in the presence of iodine?
Question 8 options:
a steak
a hard boiled egg
noodles, bread, or crackers
chicken
The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.
Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.
Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.
