Milkweed nectar is rich in a sugar, which is called sucrose. This sugar is a disaccharide, made of glucose and fructose. Sugar is broken down into glucose and fructose in the body, using an enzyme called invertase.
The three phases of cellular respiration are as:
Glycolysis is the process by which glucose is converted into energy. In glycolysis, two ATP molecules are made per glucose molecule. Two NADH molecules are also made. Aerobic organisms, such as monarch butterflies, can further process sugars. In the mitochondria, one CO₂ molecule is removed from the sugar, and one NADH is produced.The Kreb cycle is a series of eight enzymatic reactions that produce energy in the form of ATP. In the Kreb cycle, acetyl-CoA is completely oxidized to produce carbon dioxide. This process is aided by the production of NADH, FADH₂, and a molecule of GTP. Oxaloacetate is regenerated to continue the cycle.Oxidative phosphorylation is the process that generates a proton gradient across the inner mitochondrial membrane. This gradient is used by the V ETC complex to generate energy. The V ETC complex is located in the inner mitochondrial membrane, and as protons flow back and forth through the complex, it catalyzes the phosphorylation of ADP to produce ATP.Learn more about cellular respiration https://brainly.com/question/14158795

how do the locations where photosynthesis occurs differ in prokaryotes and eukaryotes
Photosynthesis takes place on the folds in prokaryotes and in specialised organelles in eukaryotes. Prokaryotic cells don't have specific organelles or a remote nucleus.
What is photosynthesis?
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.
Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue.

A biologist used the radioisotope tritium (3H) to label thymine and the radioisotope carbon-14 (14C) to label uracil. She then incubated a growing bacterial culture with both labeled bases. After five hours of incubation, the biologist extracted polynucleotides from the cells and separated them into three groups, each containing a range of different polynucleotide lengths. The first group contained the shortest polynucleotides. The second group contained polynucleotides of midrange length, and the third group contained the longest polynucleotides. Then she determined the percentage of each radiolabel in each fraction. Her data are summarized in the table above. Which statement represents a reasonable hypothesis that could explain these results?Uptake of 3H label resulted from DNA replication, and uptake of 14C label resulted from transcription.
The statement that represents a reasonable hypothesis that could explain these results is Uptake of 3H label resulted from DNA replication, and uptake of 14C label resulted from transcription.
The process by which a double-stranded DNA molecule is duplicated to form two identical DNA molecules is known as DNA replication. Replication is necessary because when a cell splits, the two new daughter cells must have the same genetic information, or DNA, as the parent cell.
The process of transcribing a piece of DNA into RNA is known as transcription. Messenger RNA is created when segments of DNA are translated into RNA molecules that can encode proteins. Other DNA sequences are transcribed into RNA molecules known as non-coding RNAs. Only 1-3% of total RNA samples contain mRNA.

Which of the following statements about human impact on trees is true?
a.Human activity always has a negative impact on trees.
b.All human uses of trees require destruction of the trees.
c.Human activity has had both a positive and negative impact on trees.
d.Cutting down trees is the only activity that has a negative impact on trees.
Answer:
c. Human activity has had both a positive and negative impact on trees.
Human activity can have negative impacts on trees, such as deforestation and clearcutting, but it can also have positive impacts, such as tree planting and reforestation efforts. It is not true that all human uses of trees require destruction of the trees, as humans also use trees for a variety of non-destructive purposes such as recreation, wildlife habitat, carbon sequestration, and aesthetic value. And cutting down trees is not the only activity that has a negative impact on trees, other human activities such as air pollution, soil degradation, water pollution can also have negative impacts on trees.

What is the first and the most important step in the resuscitation of this newborn?
The single most crucial and efficient phase in cardiopulmonary resuscitation of a critically ill newborn is lung ventilation. The newborn should be placed under a radiant heat source to offer warmth. The baby should then be dried off, their airway should be cleared with a bulb syringe or suction catheter if necessary, and their breathing should be stimulated.
Rescuers should make sure that aided ventilation is being administered as optimally as possible before beginning chest compressions because ventilation is the most effective intervention in neonatal resuscitation and because chest compressions are likely to compete with good ventilation. Thus successful resuscitation depends on efficient ventilation. One cannot always foresee or forecast the necessity for neonatal resuscitation at birth.

G. Color blindness is a x-linked genetic disorder. If a woman, who is a carrier for color blindness, marries a normal man, then what is the percent possibility that their sons will be colorblind
If the mother is carrier color blind and the father is normal, the percent possibility that their sons will be colorblind is 25%.
Color blindness is an inherited/genetic disorder that is passed from parents to their children, this disorder is often also called sex-linked because this disorder is carried by the X chromosome. This means that the Y chromosome does not carry the color blindness factor. The genotype of color-blind i.e.:

What is the percentage of having tall pea plants in the offspring?
The percentage of having tall pea plants in the offspring is about 75%
A person who has two copies of the allele that codes for the dominant characteristic is said to be homozygous-dominant for that trait. This allele, which is sometimes referred to as the "dominant allele," is typically denoted by the uppercase version of the letter used for the associated recessive characteristic (such as "P" for the dominant allele producing purple flowers in pea plants). An organism's genotype is symbolized by a doubling of the trait's symbol, such as "PP," when it is homozygously dominant for that trait.
Refers to a trait that can only be seen in homozygous individuals; it is a trait that is often hidden by other inherited qualities but persists in populations of heterozygous individuals.

What are the genotypes of the F2 generation?
Answer:
The genotypes of the F2 generation depend on the genotypes of the parents in the F1 generation.
Explanation:
If the F1 generation is produced by crossing two individuals with different genotypes, the F2 generation will have a variety of genotypes.
For example, if the F1 generation is produced by crossing a homozygous dominant individual (AA) with a homozygous recessive individual (aa), the F2 generation will have a 1:2:1 ratio of genotypes: one quarter will be homozygous dominant (AA), half will be heterozygous (Aa), and one quarter will be homozygous recessive (aa).
If the F1 generation is produced by crossing two heterozygous individuals (Aa and Aa), the F2 generation will have a 3:1 ratio of genotypes: three quarters will be heterozygous (Aa) and one quarter will be homozygous recessive (aa).
It is also possible for the F1 generation to be produced by crossing two individuals with more complex genotypes, in which case the F2 generation will have a variety of genotypes based on the combination of the parents' genotypes.

Option c is Correct. The oceans are the final uncharted territory on earth, according to the executive summary from the office of the chief scientist at NOAA from March 1998.
Nearly the whole surface of our planet has been explored by humans. Each desert has been traversed by humans. We have traversed almost every peak, as well as the skies and even the universe beyond.
We still haven't made much progress in exploring our waters despite all of this. Over 80% of the oceans on Earth have not yet been fully mapped out.
