How do the relative sizes of the external and internal jugular veins differ in the human and the pig?

Biology

Ksivusya [100]2 years ago
5 0
The jugular veins are the veins responsible for bringing deoxygenated blood from the head to the heart. There are two sets of jugular veins, the internal and external ones. In pigs, the internal and external jugular veins are similar in size, while in humans the internal jugular vein is bigger in diameter than the external.

"Cells in the lining of the stomach produce a protein called pepsinogen. When this protein is released into the chamber of the s
Sergio [31]

This is an example of Precursor gene regulation (protein translation) type of eukaryotic gene regulation.

<u>Explanation:</u>

The source which breakdown proteins into smaller amino acid is pepsin and generated as top cells within stomach lining or membrane, responsible for pepsinogen emission inside stomach. It is represented as zymogen having an extra 44 amino acids linkage as its primary structure. Hydrochloric acid (HCl) releases this zymogen which is emitted from the parietal cells in the stomach lining.

Once food is consumed, the hormone gastrine and the vagus nerve cause the secretion of both pepsinogen and HCl from the stomach lining. Hydrochloric acid induces an acidic environment that allows pepsinogen to unfold in an autocatalytic manner and thus generates pepsin the active form.

* Describe at what point in the cell cycle cells begin to divide uncontrollably.
Butoxors [25]

Every cell in the body goes through a life cycle. Cells grow and divide to replace cells that are lost because of normal wear and tear or injury. Different cells grow and die at different rates. Some cells, such as epithelial<span>epithelialA thin layer of epithelial cells that makes up the outer surfaces of the body (the skin) and lines hollow organs, glands and all passages of the respiratory, digestive, reproductive and urinary systems.</span> cells, reproduce quickly. Other cells, like nerve cells, grow slowly. Both normal cells and cancer cells go through a sequence of steps, or phases, when they form new cells. This is called the cell cycle.

What are the advantages to using prokaryotic as host systems for genetic engineering? What are the limitations to genetic engine
ahrayia [7]

Answer and Explanation:

The manipulation of the gene is called genetic engineering. In genetic engineering, fragments of genes are cloned by leading the genes into the host cell. The advantage of using a prokaryotic host system in genetic engineering is that bacterial cells are used to produce commercially significant products. For example, human growth hormone helps to treat dwarfism, and human insulin production, which is used to treat diabetes. The bacterium P.putida is created by genetic engineering, which is used to break down petroleum products. Genetic engineering also carries some potential risks, such as transferring the selected gene into another speice, benefit one species can harm another speice. Therefore genetic engineering must be used in limit in prokaryotes. These limitations are also addressable in single-cell eukaryotic systems. Biologics-based therapeutic medicines such as a vaccine, gene therapies, and cell therapies known as bioproduction are produced. Medicines are so complex that they can only be formed in a living system. Biopharmaceuticals, value-added food, fuels, chemicals, antibiotics, and many other products are produced by bioproduction.

A group of similar cells that perform a particular rimetion is called akam)
GaryK [48]

Answer:

Tissue

Explanation:

A group of similar cells that perform a particular function is called a tissue. Each cell type has special features that enable it perform a particular function efficiently. Each cell is highly specialized. groups of such specialized cells are normally assembled together to form a tissue which performs a specific function like the epithelial tissue, muscular tissue.
