The dorsal and ventral face of the leaf is surrounded by a cuticle secreted by the epidermis. In the middle, there are chlorenchyma and lacunar parenchyma cells. In the ventral face we can also find guard cells. Option D) 2 and 4.​

Usually, in a leaf, we can identify two faces, the dorsal and the ventral ones. Both of them are protected by a dermal system, the epidermis that produces the cuticle.

On the ventral face, we can differentiate the stomata. Stomata are small pores placed in the leaf's surfaces, whose opening is regulated by two guard cells surrounding them.

Among other organelles, guard cells have chloroplasts to photosynthesize.

Particulate Matter (PM) is the air pollutant least successfully removed from the air by technologies in developed nations.

Particulate matter is a mixture of solid particles and liquid droplets found in the air. Particulate matter is made up of liquid droplets, dust, dirt, soot, and smoke.

Particulate matter can be inhaled and can cause serious health problems, including respiratory and cardiovascular disease. PM is generated by a variety of sources including combustion, construction, and natural sources such as dust storms.

While many technologies have been developed to reduce PM emissions, they are not always effective in removing PM from the air, especially in heavily industrialized areas due to several factors.

One major reason is that particulate matter can come from a wide variety of sources, such as industrial emissions, transportation, agriculture, and natural sources such as dust storms and wildfires. This makes it difficult to target and effectively reduce the sources of particulate matter.

Another reason is that particulate matter can be transported over long distances by winds, making it difficult to contain and control. This means that even if local sources of particulate matter are reduced, it can still be a problem due to pollution from other areas.

Additionally, particulate matter is very small and can be hard to filter out of the air. The cost and technology required for filtration systems, like HEPA filters or electrostatic precipitators, can be expensive and challenging to implement, especially in developing countries.

In conclusion, particulate matter is a challenging air pollutant to remove, due to its various sources, its transportability, and the difficulty of filtration. A multi-pronged approach including reducing the sources, controlling emissions, and using advanced filtration systems is needed to effectively reduce particulate matter in the air.

In the case of the Galápagos finch species, it made sense that they would resemble one another as well as mainland finches, who most likely had a common ancestor. The best proof that organisms evolved from a common ancestor is similar DNA sequences. The existence of fossils proves evolution.

The hot springs of Geyser Basin in Yellowstone National Park are a great place to observe the growth of thermophiles. Thermophilic microorganisms can live in very hot water. This statement is true.

The term "thermophile" refers to bacteria that can grow at temperatures up to 55°C (minimum 45°C, optimum temperature range 55-65°C, maximum 80°C). Hyperthermophiles (extreme thermophiles) are microorganisms that can grow at temperatures as high as 113°C, ideally 80°C. Examples include Bacillus stearothermophilus, Thermoplasma acidophilus, and Thermus aquaticus.

High affinity transport (Kt) of L-Alanine feature of the kinetics of L-Alanine transport would provide evidence that DOM is an important source of nutrients under low-food conditions.

This biochemistry question is categorized as "Assemblies of molecules, cells, and groups of cells within single cellular and multicellular organisms" in terms of its subject matter. The answer to this issue is A because no transporters are saturated with L-alanine under low-food conditions, making the transport capacity unimportant. Only high affinity transporters would be able to assist L-alanine uptake at low concentrations, hence the transporter's affinity for L-alanine would be crucial.

Because you are expected to utilize your understanding of transport kinetics to forecast the characteristics of transport that would be significant under low L-alanine conditions, this question falls under the category of scientific reasoning and problem solving.

As the cell radius increases, the surface area increases as the radius squared, but the volume increases as the radius cubed (much faster). Therefore, as the cell size increases, the surface area to volume ratio decreases.

Cell proliferation reduces the surface area to volume ratio. This is because as a cell grows, its volume (its internal contents) increases faster than its surface area (its cell membrane).

As cells grow larger, the surface area to volume ratio decreases dramatically, similar to an agar cube. Larger cells have to transport substances across membranes, but they deliver a larger volume and a proportionately smaller surface area.

When these molecules are linked together, the bonds between them store energy. This energy is refers to potential energy. When compared to the smaller amino acid subunits, the potential energy stored in the protein is much greater. This is due to the fact that the potential energy stored in a protein is the sum of the potential energy of all the individual amino acids.
