Answer:
Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells
Explanation:
Each cell type contains only the active parts of the DNA needed for that cell type Each cell type has only one chromosome containing the DNA needed for that cell type. Each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells Each cell has multiple copies of DNA that are affected in different ways by the environment to change the function of the cell at regular intervals.The correct answer would be that each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells .
Cell differentiation occurs when a specific segment of the DNA of a cell is expressed during gene regulation and control. The segment of DNA expressed would be dependent on the function the cell is meant to perform. Thus, if cell A is meant to perform an excretory role and cell B is meant to perform a digestive role, even though cells A and B contain the same DNA, different segments of their DNAs would be expressed so that each cell becomes adapted to its role.
13. Which statement correctly compares a function of lipids to a function of proteins in the body?
A. Fats insulate the body, and proteins control contraction.
B. Fats cushion the organs, and proteins insulate the body.
C. Fats coordinate body activities, and proteins provide sugars.
D. Fats store energy, and proteins provide the primary fuel for cell respiration.
The correct answer is A.
Fats thermally insulate the body, while proteins like actin and myosin form myofibrils which are the anatomical support for contraction.
Lipids and proteins are the macromolecules present inside living cells. Lipids are made of fats that insulate and proteins are involved in contraction. Thus, option A is correct.
What are the functions of lipids and proteins?Lipids have been the polymers that make the larger molecules and have been constituted of glycerol and fatty acids (triglycerides). These are stored in the fatty tissues called adipose tissues and provide insulation to the body.
On the other hand, proteins are macromolecules constituted of amino acid sequences (polypeptide). These are involved in the muscle contraction that allows the movement and motion of the muscular and skeletal systems.
Therefore, option A. the fats and proteins are involved in insulation and contraction.

Which population is most likely to be in Hardy-Weinberg equilibrium?
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
a large population of prairie grasses that lives in an ecosystem that is frequently burned by wild fires
a medium-sized population of birds that lives on a chain of islands that have different food sources
a medium-sized population of bacteria that lives on crop plants that are frequently sprayed with pesticides
Answer:
a large population of ocean fish that lives in an unpolluted ecosystem that has abundant food
Explanation:
This is because the Hardy-Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. So if the large population of ocean fish isn't being disturbed by the pollution (unpolluted) and they have an abundant source of food they should in Hardy-Weinberg equilibrium since no major changes are happening.

Which statement best describes the energy flow as it passes from producers to tertiary consumers?
A. 10% of the energy is transferred through each trophic level.
B. 100% of the energy produced passes to each trophic level.
C. 50% of the energy produced is transferred through each trophic level.
D. 1% of the energy is lost as heat is transferred through each trophic level.
Answer:
The answer is A
Explanation:
At any given trophic level, only 10% of the energy is transmitted to the next level; the remaining 90% is primarily wasted as heat during metabolic activities. Thus, option A is correct.
What is the role of energy flow in an ecosystem?Typically, only 10% of energy is transmitted from one trophic level to the next. This restriction on the number of trophic levels that an ecosystem may support is referred to as “the 10% rule.” organisms that are alive and the energy they hold.
Each trophic level's energy content diminishes as it progresses through an ecosystem.
The 10% Rule states that only 10% of the energy will be transferred when it moves from one trophic level to the next in an ecosystem.
Therefore, An energy pyramid provides a graphic representation of energy loss at each level of the feeding stages of species in an ecosystem.

Messenger RNA (mRNA) travels from the nucleus of a eukaryotic cell to the ribosome. At the ribosome, the amino acids are lined up in order as the tRNA molecules line up with complementary bases on the mRNA. This process is called _____ and results in the formation of _____.
Answer:
The correct answer is - translation, polypeptide/amino acid chain.
Explanation:
The translation is the process that involves the movement of mRNA from the nucleus to the ribosome and where amino acids are formed in sequence linked with one another in the same order as the transfer RNA line up with the complementary bases encoded on the messenger RNA or mRNA.
This amino acid chain or the polypeptide folds in a specific way to active protein for the specific function or expression. This process is the last stage or phase of protein synthesis.

Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Higher
Equal
Answer:
higher is the concentration of solute
The liquid having the highest solute concentration. Hypotonic: A solution with a low solute content. Thus, option B is correct.
What concentration of solute (dissolved stuff) than isotonic?When two liquids with varying solute concentrations are compared, the higher solute concentration solution is hypertonic, whereas the lower solute concentration solution is hypotonic. The solute concentration in isotonic solutions is the same.
A solution that has the same concentration as another solution is said to be isotonic.
A solution that contains the same amount of salt as blood and cells. Isotonic solutions are typically used as intravenous fluids in hospitalized patients.
Equal amounts of each solution will flow across a semipermeable membrane separating two solutions. Because the solvent and solute concentrations are the same.
