B) It applies a selective pressure for larger, faster growing fish. C) The fish in the population produce more eggs to compensate. D) The fish in the population produce healthier eggs to compensate. E) The population comes to be dominated by smaller, slower-growing individuals.

Homozygous refers to the condition where an individual possesses two identical alleles for a particular gene, either both dominant or both recessive, impacting the expression of traits and contributing to the genetic diversity within a population.

Homozygous refers to a genetic condition in which an individual possesses two identical alleles for a particular gene, both inherited from either the mother or the father. In a diploid organism, such as humans, each individual inherits one allele from each parent for a given gene.

The term homozygous is derived from "homo," meaning same, and "zygote," which is the initial cell formed when two gamete cells (sperm and egg) fuse during fertilization. The alleles can be either dominant or recessive, representing different forms of a gene. If an individual is homozygous dominant, it means both alleles are the dominant form. If homozygous recessive, both alleles are the recessive form.

For example, in a simplified scenario where "A" represents the dominant allele for a certain trait and "a" represents the recessive allele, an individual with the genotype "AA" is homozygous dominant, while an individual with the genotype "aa" is homozygous recessive.

Homozygosity plays a crucial role in determining the expression of traits in an organism. It influences the phenotype, or observable characteristics, of an individual. Homozygous individuals express traits according to the specific alleles they carry, providing insight into the inheritance patterns and diversity within a population.

When you stub your toe, sensory nerves send a signal to the spinal cord, where an interneuron helps form a reflex arc that prompts a motor nerve to instantly contract the muscles for withdrawal, all without involving the brain.

When you stub your toe, a rapid sequence of events occurs within your nervous system to produce a response. The peripheral nervous system sends a signal from the injured toe to the spinal cord through sensory nerves. At the spinal cord, the signal is transferred to an interneuron and then to a motor nerve, which relays the command back to the muscles in your toe and leg. This connection, known as the reflex arc, allows for an immediate withdrawal response without involving the brain, permitting a quick reaction to potentially harmful stimuli. If you were to step on a sharp object, the pain-sensing nociceptors would activate the motor neurons for the tibialis anterior muscle, causing dorsiflexion of the foot, while an inhibitory interneuron would prevent the plantar flexion by inhibiting the gastrocnemius and soleus muscles, thus minimizing potential injury.

If you'd like to know why:

Ocean trenches are made when two oceanic plates CONVERGE. This is what we call convergent boundary, which is the process where two plates collide. When this happens, the less dense plate subducts or goes under the other plate. The point where the plate goes under is marked by a trench.  

A trench is a deep, narrow section of the ocean floor, often formed by tectonic activity. An example is the Mariana Trench, the deepest part of the world's oceans. It would be depicted on an illustration as the deepest, narrow part of the ocean floor.

In the context of geography, particularly geology and oceanography, a trench refers to a long, narrow, and extremely deep part of the ocean floor. These are typically formed by tectonic activity where one tectonic plate subducts or moves underneath another. An example of a trench would be the Mariana Trench in the Western Pacific Ocean. It is the deepest part of the world's oceans, with a maximum depth of more than 36,000 feet. When referring to the illustration, locate the deepest and narrow part representing the ocean floor; that would likely be the trench.

Squamous and cuboidal epithelium, while similar in being epithelium, differ in function and location, with the squamous epithelium primarily serving as a protective barrier, and cuboidal epithelium contributing to secretion and absorption.

The two similar epithelium referred to here, without specific given examples, might be squamous and cuboidal epithelium. Squamous epithelium, which is flat and scale-like, primarily functions as a barrier, protecting underlying tissues. For instance, it can be found in the skin where it acts as a barrier to the external environment. In contrast, cuboidal epithelium is square or cube-shaped and functions in secretion or absorption. Examples are the kidney tubules where cuboidal cells reabsorb water and electrolytes, or glandular tissue where these cells secrete substances such as hormones. By their shape and structure, they define their function in the body.

The surface tension of water molecules explains how some insects can walk on water.

Surface tension is a property of liquids that occurs because of the cohesive forces between molecules at the surface. In the case of water, each molecule is held to the surrounding molecules by strong hydrogen bonds. These cohesive forces are exerted in all directions on molecules in the center of the liquid.

However, molecules at the surface experience the force only from the sides and below, which pulls them more closely together and creates a 'surface film' that is harder to break. This surface film allows small, lightweight insects, like water striders, to walk on water.

They distribute their weight over a larger area, which prevents them from breaking through the surface tension and sinking. Essentially, they take advantage of the strong intermolecular forces at the surface of the water to support their weight.

The Endoplasmic Reticulum and Golgi Apparatus are the organelles included in membranous canals, and vacuoles are membrane-bound sacs involved in storing and maintaining cell structure.

The cellular organelles that would be included in membranous canals and vacuoles are the Endoplasmic Reticulum (ER) and the Golgi Apparatus. The ER is a network of membranous tubules and sacs called cisternae, and it plays an important role in the synthesis of proteins and lipids. The Golgi Apparatus, on the other hand, is involved in the sorting, modification, and shipping of products produced in the ER. Both of these organelles constitute the 'membranous canals' in a cell. Vacuoles are essentially membrane-bound sacs filled with water containing inorganic and organic molecules including enzymes, and play a crucial role in maintaining the shape of plant cells and in storing waste products.
