When we look at a leaf, the colors of light that we see are the colors of light that are reflected off its surface. The other colors of light are absorbed by the leaf.

When light strikes an object, some of the light is reflected, and some of the light is absorbed. The color of an object is determined by the colors of light that are reflected. A leaf appears green because it reflects green light and absorbs other colors of light such as red, blue, and yellow.

This is because chlorophyll, the pigment that is responsible for photosynthesis in plants, absorbs red and blue light most efficiently and reflects green light. Other pigments such as carotenoids and anthocyanins also present in the leaves, can absorb different wavelengths of light and make the leaf appear in different shades of yellow, orange, and purple.

It is worth noting that the color of the leaf can change depending on the season, the environmental conditions, and the health of the plant.

When humans ingest larvae, eggs, or other forms of a microorganism in contaminated foods, they may become infected with a parasitic roundworm called Ascaris lumbricoides.

This roundworm is one of the most common intestinal parasites in humans and it is also known as human ascariasis. The infection is caused by ingesting food or water that is contaminated with Ascaris eggs, which hatch in the small intestine and release the larvae.

The larvae then migrate through the intestinal wall and into the liver and lungs, before returning to the small intestine where they mature into adult worms.

Ascaris lumbricoides are commonly found in areas with poor sanitation and hygiene, and it is most common in tropical and subtropical regions, where it is estimated to infect up to 1.2 billion people worldwide.

Answer:

(c) Vascular Cambium

Explanation:

The primary source of stem thickening in plants is the vascular cambium. The vascular cambium is the type of cell involved in secondary growth of a plant, which is when the plant grows wider. This type of cell is found in the stems of plants, and it divides and creates new cells, causing the stem to grow thicker as new cells are added. You can see recorded evidence of this type of growth when you look at the rings of trees. Each ring represents a growing season, where the tree added girth as well as height. Thicker rings indicate better growing seasons because the vascular cambium had access to enough energy to divide more frequently.

The EGF ligand is the diffusible extracellular element in the process of vulval cell differentiation in C. elegans.

All EGF ligands are synthesized as type 1 transmembrane precursors that undergo cleavage of the extracellular domain to release a soluble ligand that then binds and activates EGFR. This cleavage event is typically mediated by members of the α-disintegrin and metalloprotease (ADAM) family.

Upon ligand binding to the extracellular domain of EGFR, its transmembrane domain rotates or twists parallel to the plane of the cell membrane, resulting in the reorientation of the intracellular kinase domain dimer from a symmetrical inactive conformation to an asymmetrical active conformation. (“rotation model”).

EGFR plays a critical role in the initiation of signaling that controls the behavior of epithelial-derived epithelial cells and tumors.

Cells surrounding stomata that, through osmosis, regulate the openings and closings of the stomata are called guard cells.

Guard cells are specialized cells that surround the stomata, which are small openings on the surface of leaves that allow for the exchange of gases such as carbon dioxide and oxygen.

The guard cells regulate the size of the stomata by changing their shape through the process of osmosis. When the guard cells absorb water, they swell and cause the stomatal pore to open. When the guard cells lose water, they shrink and cause the stomatal pore to close.

The regulation of the stomatal aperture is essential for plants' survival as it helps the plants to balance their water loss and CO2 uptake.
