Frequency affects the pitch. The quantity of sound waves that reach the ear in a specific amount of time is known as frequency. According to the text, the pitch relies on frequency. Option (d) is correct.

The frequency of the sound waves affects pitch. The pitch increases as the frequency increases. While the loudness of a sound depends on the amplitude of sound waves, the pitch of a sound depends on its frequency. Sound wave size is determined by amplitude. It depends on how much energy created the initial waves. Waves with a larger amplitude produce louder sounds because they are more energetic and intense.

The energy of sound waves disperses more as they move away from their source. According to the data, pitch perception is influenced by tone strength; below 1000 Hz, pitch tends to decrease with increasing loudness, and beyond 1000 Hz, pitch tends to increase. If a tone is not long enough for pitch to be assigned, it is heard as a CLICK. The relationship between pitch and sound frequency is straightforward. Higher the frequency,higher will be the pitch and vice-versa.

The process by which a fish blastula (a ball of simple cells) develops into a complex fish with many organs and parts is called embryonic development. This process is controlled by a complex series of genetic and cellular processes that result in the differentiation of the blastula cells into the various cell types and tissues that make up a fish.

During embryonic development, the cells of the blastula begin to differentiate into two main cell types: the epiblast and the hypoblast. The epiblast cells give rise to the ectoderm, which forms the outer layer of the developing fish, and the hypoblast cells give rise to the endoderm, which forms the inner layer.

As development continues, the cells in the ectoderm and endoderm begin to differentiate further into the various tissues and organs of the fish. For example, the ectoderm gives rise to the skin, nervous system, and sensory organs, while the endoderm gives rise to the digestive system and respiratory organs.

In addition to this process of cell differentiation, embryonic development also involves the growth and specialization of cells and tissues through a process called morphogenesis. This process results in the formation of the various structures and organs of the fish, such as the heart, liver, and kidneys.

Overall, embryonic development is a complex and dynamic process that involves the coordination of many different genetic and cellular processes. Through this process, the simple cells of the fish blastula are transformed into a complex and highly organized organism with many specialized organs and parts.

Explanation:

The fish blastula is able to go from a ball of simple cells to a complex fish with many organs and parts through the process of embryonic development.

During embryonic development, the cells of the blastula undergo a series of changes that allow them to differentiate into the various tissues and organs of the adult fish. This process is controlled by a complex network of genes and regulatory molecules, which direct the cells to take on specific roles and functions.

One of the key steps in this process is called gastrulation, which occurs during the early stages of embryonic development. During gastrulation, the cells of the blastula begin to rearrange themselves, forming a two-layered structure called the gastrula. The outer layer of cells, called the ectoderm, will eventually give rise to the skin, nervous system, and other tissues. The inner layer of cells, called the endoderm, will give rise to the digestive system and other internal organs.

After gastrulation, the cells of the ectoderm and endoderm continue to differentiate and specialize, forming the various tissues and organs of the adult fish. This process is called organogenesis, and it involves the coordinated growth and development of the different cell types.

Overall, the fish blastula is able to go from a ball of simple cells to a complex fish with many organs and parts through the process of embryonic development. This process involves the coordinated growth and differentiation of the cells of the blastula, leading to the formation of the various tissues and organs of the adult fish.

Explanation:

Motor tracks in the spine can be found in the anterior (front) portion of the spinal cord. The spinal cord is a long, slender bundle of nerve tissue that extends from the base of the brain down through the spinal column. It is divided into two main regions: the posterior (back) region, which contains sensory neurons that carry information about sensation from the body to the brain, and the anterior (front) region, which contains motor neurons that carry information from the brain to the muscles and other organs in the body.

The motor tracks in the spinal cord are located in the anterior region, along with the sensory tracks that carry information from the body to the brain. These tracks are organized into columns of neurons called tracts, which are grouped according to the type of information they carry and the areas of the body they serve. Motor tracts carry information from the brain to the muscles and other organs, controlling movements and other functions.

Overall, motor tracks in the spine can be found in the anterior portion of the spinal cord, along with the sensory tracks that carry information from the body to the brain. These tracks are essential for controlling movements and other functions in the body.
