which ventricles are divided by the septum pellucidum?

Answers

Answer:

The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain.

Explanation:

The septum pellucidum separates the lateral ventricles. The lateral ventricles are divided into two halves by the septum pellucidum, a thin, vertical partition of tissue. It is formed of white matter and is situated in the frontal region of the brain.

The corpus callosum, a sizable bundle of nerve fibers that links the two hemispheres of the brain, is considered to have been influenced by the septum pellucidum.

The biggest ventricles in the brain are called the lateral ventricles. They are situated on each side of the brain, and cerebrospinal fluid is contained inside them (CSF). The CSF assists in removing waste from the brain and spinal cord in addition to cushioning the brain and spinal cord.

In eukaryotes, gene expression is regulated mostly by _____.

Answers

Answer:

Gene expression in eukaryotic cells is regulated by repressors as well as by transcriptional activators. Like their prokaryotic counterparts, eukaryotic repressors bind to specific DNA sequences and inhibit transcription.

Explanation:

In eukaryotes, gene expression is regulated mostly by transcription factors.

What are transcription factors?

Transcription factors are proteins that bind to DNA in the promoter region of a gene, and they play a critical role in controlling when and to what extent a gene is expressed.

They can either activate or repress gene expression by promoting or inhibiting the recruitment of RNA polymerase. Transcription factors are themselves regulated by a variety of signals, including hormones, growth factors, and other external cues, as well as by feedback loops and other regulatory mechanisms within the cell.

Ultimately, this complex interplay of factors allows eukaryotic cells to precisely control which genes are expressed, when they are expressed, and to what degree, enabling them to respond to changing internal and external environments.

Answers

Answer:

Houses nasal conchae to enhance turbulence for filtering air. larynx. Prevents food and liquid from entering the rest of the respiratory tract.

Explanation:

Houses nasal conchae to enhance turbulence for filtering air through nasal cavity. Hence, the correct option is A.

What is nasal cavity?

It is a large air filled space within the nose and is part of the respiratory system. It is lined by an inner thin layer of moist mucous membrane which helps to humidify and filter the air as it is breathed in.

The nasal cavity is divided into two parts-the right and left nasal cavities, separated by a thin bony wall called septum. It is involved in the sense of smell, as small receptors located in the mucous membrane of the nasal cavity are responsible for detecting different odors.

Overall, the nasal cavity is a crucial part of the respiratory system and plays an important role in protecting the body from inhaled irritants, facilitating the sense of smell. Hence, the correct option is A.
