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.
which do all cells need in order to function?
a: oxygen
b: water
c: carbon dioxide
d: offspring
Answer:
A. Oxygen ( for animals )
B and C ( for plants )
Explanation:
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. During cellular respiration, oxygen is needed. Carbon dioxide is the product of cellular respiration.
In the event you are referring to plants, then both water and carbon dioxide are needed for photosynthesis.
Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
What are Cells?Cells may be defined as the building blocks of living organisms. They are considered the basic structure and functional unit of life. All living beings are made up of cells.
Antony von Leeuwenhoek discovered the living cell for the very first time in 1674 with the help of an improved microscope in Pond water.
Cells require oxygen because they have the ability to break down food particles in the presence of oxygen to derive energy for metabolic activities. This process of breaking down food in the presence of oxygen is known as cellular respiration.
This is because oxygen functions as a final electron acceptor in the electron transport chain to synthesize an energy molecule known as ATP.
Therefore, Oxygen is required by all cells in order to function properly. Thus, the correct option is A.

What are some problems that can occur from an altered gene that makes hemoglobin? (Site 1)
Answer:
If mutations that produce hemoglobin S and beta thalassemia occur together, individuals have hemoglobin S-beta thalassemia (HbSBetaThal) disease. Abnormal versions of beta-globin can distort red blood cells into a sickle shape. The sickle-shaped red blood cells die prematurely, which can lead to anemia

HELPPP ASAP! TIMED! 10 MINUTES LEFTT! How is cold front formation different from stationary front formation?
A.Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances
against a warm air mass.
B.Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is
trapped between two cold air masses.
C.Cold fronts form when a warm air mass moves over a cold air mass, while stationary air fronts form when a cold
air mass moves over a warm air mass.
D.Stationary fronts form when a warm air mass is trapped between two cold air masses, while cold fronts form when
a warm air mass moves over a cold air mass.
Answer: Stationary fronts form between warm and cold air masses, while cold fronts form when a cold air mass advances against a warm air mass. Cold fronts form between two air masses that barely move, while stationary fronts form when a warm air mass is trapped between two cold air masses.
Explanation:
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.

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.

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.

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 student applies 55 N of force to a box on four types of surfaces. Each surface has a different value for Ffric-
On which surface is the student not able to move the box?
A. A
B. C
C. D
D. B
Answer:
D
Explanation:
The surface is the student not able to move the box is D.
What is force?Force is defined as an outside force that has the potential to alter how a body is moving or resting. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. The idea of a force encompasses both living and non-living things. The body can change its size, shape, and direction when force is applied. As we discovered in a previous session, forces are significant because they induce modifications to motion.
Net force is defined as all of the forces pulling on a thing combined. The net force, which is a single force, replaces the original forces' influence on the particle's motion. The top 5 words that are similar to "net force" in terms of this word similarity engine are resultant force, force, acceleration, physics, and rotation.
Thus, the surface is the student not able to move the box is D.
