The statement that explains the difference in the distribution of solar energy on Earth’s surface is that the Earth’s curved shape and tilt on its axis do not allow the sun’s rays to fall evenly on its surface. That is option D.
What is solar energy?The solar energy is the energy that is derived from the sun which occurs due to the nuclear fission reaction occuring within the sun.
The earth is known to have a spherical shape and revolves round about its own axis as it moves round about the sun.
The solar energy rays released from the sun won't be able to reach the whole surface of the earth because of its shape but it can reach a portion of the earth at a time.

In the diagram above, label the following:
The DNA Ladder
The positive end
The negative end
The direction DNA moves (indicate with an arrow)
The smallest/shortest RFLP
The largest/heaviest RFLP
In gel electrophoresis, the DNA ladder is the band pattern used to compare other samples. The negative end is located in the upper part of the gel, while the positive end is in the lower part. The migration direction is from the negative end to the positive one. Smaller fragments migrate further than the largest fragments. Image attached.
What is Gel electrophoresis?Gel electrophoresis is a method based on DNA fragment sizes and used to analyze polymorphism resulting from the DNA sequence variation among individuals.
Through this method, DNA fragments of varying lengths from samples cut with restriction enzymes are separated according to their size and charge.
All the different DNA samples are placed in one of the gel extremes.
A control DNA sample is used as a reference since its fragment sizes are already known. This is the DNA ladder.
An electric current acts on the gel and triggers the migration of the DNA fragments.
Fragment motion occurs from the negative end toward the positive one. This is because DNA fragments are negatively charged, so they are attracted to the positive side of the gel.
The smaller fragments can move further than larger fragments.
Fragments separate and create band patterns. Once the bands are separated, each of them can be compared with the control bands to get to know their approximate sizes.
Since I do not have the original diagram, in the attached files you will find a random image with the labels on it. You can use it to complete your task.

A dihybrid cross represents a mating experiment between two organisms that are identical hybrids for two traits. Hybrid organisms are heterozygous, meaning they have two different alleles at a particular genetic position or locus.
In a dihybrid cross, the parents have different allele pairs for each trait. One parent has a homozygous dominant allele and the other parent has a homozygous recessive allele. All offspring generated after the F1 generation of mating are heterozygous for a particular trait.
A dihybrid cross is a cross between two organisms that are heterozygous for two different traits. Individuals with this type of trait are homozygous for a particular trait. These characteristics are determined by segments of DNA called genes.

How does water’s molecular structure affect solubility of substances on Earth? Provide a real-world example.
Explain how all the properties of water are related. Provide an example to describe the interconnectivity of each property. Be sure to include hydrogen bonding, polarity, surface tension, capillary action, cohesion, adhesion, high specific heat, and expansion upon freezing.
The polarity of water is the basis for all other observed properties of water.
What is water?Water is a highly polar covalent molecule. The dipole of water is high such that the molecule is known to have a very high dielectric constant. Given the fact that water is a very much polar molecule, there are several unusual properties of water. All these unusual properties of the water molecule stem from the fact that there a very high degree of intermolecular hydrogen bonding which holds the molecules of water together.
For instance, the polarity of water causes water to have a high surface tension. This explains why an umbrella could be used to hold water and protect the person using it from being drenched by the rain.

According to the research, the correct option is lactase. It is a sugar from the list based on the naming structure provided for Enzymes and Sugars.
What is lactase?It is a double sugar composed of glucose and galactose acting as the enzyme that catalyzes the hydrolysis of the disaccharide lactose to glucose and galactose.
In this sense, it is found in the small intestine and since it is a disaccharidase that specifically breaks down lactose, when this enzyme in the intestinal mucosa is deficient or inadequate, lactose reaches the colon where it is fermented, producing lactose intolerance due to this imbalance.

lesson 4 chemical reactions and enzymes
When molecules interact and chemical bonds between them are made or broken, chemical reactions take place.
The mere proximity of two chemicals might cause some reactions. For instance, iron will produce iron oxide, sometimes known as rust, when oxygen is present. Other reactions need energy to initiate the reaction. A forest fire that is ignited by lightning is a fantastic example of something that will burn until all the fuel is consumed.Enzymes, biological molecules consisting of proteins that can be thought of as facilitators or catalysts, are frequently used in biology to help chemical reactions. Enzymes speed up the reaction or enable it to happen with less energy, and once the reaction is finished, they become available once more. They can therefore be reused because they are not consumed by the reaction. Enzymes are made to function best at a particular temperature and pH. They are less effective when used outside of this area. Because enzymes are comprised of protein, they can be denatured or destroyed at extremely high temperatures.Learn more about enzymes here:

In biology, vacuoles are membrane-bound organelles found in the cells of plants, fungi, protists, and some animal cells. They are essentially storage compartments within the cell that perform various functions depending on the type of cell and organism.
Vacuoles are typically larger in plant cells and often occupy a significant portion of the cell's volume. They can be classified into several types based on their functions:
Central Vacuole: Found in plant cells, the central vacuole is the largest and most prominent vacuole. It is responsible for maintaining turgor pressure, which helps to maintain cell shape and rigidity. It also stores water, ions, nutrients, pigments, and waste products.
Contractile Vacuole: Found in certain freshwater protists, contractile vacuoles are involved in osmoregulation. They collect and expel excess water from the cell to maintain a balanced internal environment.
Storage Vacuole: These vacuoles are involved in storing various substances such as nutrients, pigments, toxins, or waste products. In plants, they can store starch, proteins, and other compounds.
Lytic Vacuole: Found in some single-celled organisms like protists, lytic vacuoles function in intracellular digestion by containing enzymes that break down macromolecules or engulf and digest invading particles or organisms.
