Why would the pancreatic enzyme trypsin be non-functional if it was secreted in the stomach instead of the pancreas?
mel-nik [20]

Answer:

-Due to acidic pH of stomach.

Explanation:

Enzymes are generally made up of protein molecules and work at an optimum pH and temperature. This is because at change in pH and temperature leads to denaturation of proteins that cause change in active site of enzyme.

For trypsin, optimum pH is slightly basic as pH (7.5). So, trypsin would become non-functional at acidic pH due to denaturation and loss of active site.

Trypsin is a pancreatic enzyme that works at small intestine as pH of small intestine is slightly basic.Thus, if the trypsin was secreted in stomach instead of pancreas, it would be non-functional as stomach has acidic pH due to stomach acid.

Cytokinesis is the process whereby the cytoplasm of a cell divides into two in order to accommodate the already divided nucleus.

- 3.1.2

Cancer is a medical condition that means an uncontrolled division or growth of cells.

- 3.1.3

Metaphase is a stage of mitosis where chromatids line up at the equator of the cell i.e cell plate.

- 3.1.4

Centromere is a point where sister chromatids i.e. replicated chromosomes are joined before separation in the anaphase stage.

- 3.1.5

Tumour is the term given to a mass of cancerous cells. Cells repeatedly divide without control to form a mass called tumour.

- 3.1.6

Carcinoma is a type of skin cancer or rather a cancer that begins in the skin.

- 3.1.7

The cell cycle involves the interphase and mitotic phase. Interphase stage is the stage where the cell grows, multiplies its genetic material and generally prepare while mitosis is the nuclear division.

- 3.1.8

Carcinogens are biological or chemical substances that causes cancers. They are said to be factors that induce cancer.

- 3.1.9

Benign tumor are mass of cancerous cells that do not spread to other parts.

- 3.1.10

A chromatid is the half part of a replicated chromosome. Together, they are called SISTER CHROMATIDS.

Hi

Before answering this question, we need to understand first that what a mutation is. <em>A mutation basically is a change in the DNA or genetic sequence of an organism that can significantly affect or not affect the function of a specific gene in organism. </em>

Now coming towards the question, yes ofcourse it is possible that a Norwar rats population carries a different genetic mutation than a population os same rats in Africa or any other region, Why? Because sometimes environmental factors of a certain area can cause the population of a region to undergo mutation (For example harsh UV rays) and the other population donot contains that mutation. This will cause a slight change in the genetic makeup of the population of rats of Norther America. However, if the changes in genetic makeup continues to happen in North American Norway rats, a time will come when they will be genetically very different from same rats in Africa and in this way they will become a separate or different specie, this phenomenon is called speciation.

Hope it helps!

Clostridium botulinum is a bacterium that produces botulinum toxin that inhibits the release of acetylcholine. Which description
Dimas [21]

Answer:

muscle cells will  become paralyzed when there is a lack of acetylcholine

Explanation:

Based on the information provided within the question it can be said that in this scenario the muscle cells will  become paralyzed when there is a lack of acetylcholine. That is because the Acetylcholine (ACh) is an organic chemical within the brain and body that acts as a neurotransmitter to send signals from the brain to the muscle cells. Without those signals the muscle cells cannot respond and are therefore paralyzed.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.
