What are the 3 basic cellular structures that every cell needs? What's their individual function and why are each of the 3 basic cellular structures needed?
The three basic cellular structures that every cell needs are the cell membrane, the cytoplasm, and the genetic material. The cell membrane functions to regulate what enters and exits the cell, the cytoplasm provides a medium for cell organelles to function in, and the genetic material contains the instructions for cell function and replication.
Cell Membrane: The cell membrane is a thin, flexible barrier that encloses the cell and separates its internal environment from the external environment. It is made up of a phospholipid bilayer and is selectively permeable, meaning it regulates what substances enter and exit the cell.
Cytoplasm: The cytoplasm is a gel-like substance that fills the inside of the cell and contains various cell organelles, such as mitochondria, ribosomes, and the endoplasmic reticulum. The cytoplasm is important because it provides a medium for the organelles to function in and facilitates the movement of materials within the cell.
Genetic Material: The genetic material of the cell is the DNA that contains the instructions for cell function and replication. In prokaryotic cells, the genetic material is found in the cytoplasm, while in eukaryotic cells, it is found in the nucleus.
In summary, every cell needs a cell membrane to regulate what enters and exits the cell, cytoplasm to provide a medium for cell organelles to function in, and genetic material to contain the instructions for cell function and replication.

You have formulated a hypothesis: "Mangos contain more vitamin C than oranges." To test your hypothesis you measure vitamin C levels in 20 oranges and 20 mangos from trees that were grown in the same orchard under the same environmental conditions (temperature, rain, sunlight). What is the independent variable in this experiment?
Question options:
A) The amount of rain and sunlight the trees received
B) Vitamin C levels
C) The type of fruit
D) The type of soil the trees grew in
Answer:
B) the type of fruit
Explanation:
The independent variable is the value that the experimenter changes/controls. The Vitamin C levels depend on the type of fruit, so the fruit is the independent variable. Hope this helps!
The value that the experiment modifies or controls is known as the independent variable. Fruit is the independent variable because fruit types vary in their quantities of vitamin C. Thus, option B is correct.
What is the independent variable?“X” is frequently used to indicate an independent variable. It is a variable that is independent of other variables.
The elements or circumstances that you can change in an experiment are referred to as independent variables. A dependent variable's value may be directly impacted by this variable.
The definition of an independent variable is exactly what it says. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable.
Anticipated to have an impact on the dependent variable. The experiment has no effect on this. It is a variable that can be altered by researchers to examine the independent variable.
Therefore, fruit is the independent variable, to vary in their quantities of vitamin C.

If each of these food chains start with 10,000 grams of phytoplankton, how much reaches the highest trophic level in each food chain
Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.
Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.
Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.
For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.

what certain molecules are used for nadh in cellular respiration
NADH is produced during cellular respiration through the oxidation of glucose in glycolysis and the citric acid cycle.
Glucose is broken down into pyruvate in glycolysis, and NAD+ is reduced to NADH. Pyruvate is then converted to acetyl-CoA in the transition reaction, and NAD+ is again reduced to NADH. It produces one NADH molecule per pyruvate molecule.
In the citric acid cycle, acetyl-CoA is oxidized to carbon dioxide, and NAD+ is reduced to NADH. These molecules are used to produce ATP, the energy currency of the cell, through the electron transport chain.

what components make up the backbone of a dna molecule
The sides of the backbone of DNA are made of the other two molecules, 1. Sugar
2. Phosphate.
The DNA backbone and the DNA bases are the two basic structural regions of a DNA molecule. Recall that nucleotides are the building blocks of all DNA molecules. A DNA molecule's one nucleotide is made up of a phosphate group, the pentose sugar deoxyribose (which has five carbons), and a nitrogenous base (adenine, thymine, guanine, cytosine). A DNA molecule is made up of a number of these nucleotide monomers that are connected by phosphodiester linkages. The base region of a DNA molecule is made up of nitrogenous bases, but the backbone of a DNA molecule is made up of phosphate groups and deoxyribose sugars; as a result, the backbone of DNA is made up of pentose sugars. The base portion of the molecule includes adenine. There are no hexose (six-carbon) sugars in DNA. Each nucleotide molecule has one nitrogen base, one sugar group, and one phosphate group.

Long hair in guinea pigs is a recessive trait. A female guinea pig with long hair mates and
have all heterozygous offspring, what are the genotypes of the male?
Answer:
The male's genotype is homzygous short (LL)
Explanation:
This question involves a single gene coding for hair length in guinea pigs. The allele for short hair (L) is dominant over the allele for long hair (l). This means that a heterozygote will have short hair (Ll) while a guinea pig with long hair will have genotype ll.
According to this question, a female guinea pig with long hair (ll) mates and have all heterozygous offspring (Ll). This means that the male guinea pig provided only the allele for short hair (L) that made the offsprings all short. In other words, the male's genotype is LL i.e. homzygous short.
