Answer: Yes
Explanation:
his amazing artwork shows a process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein.
Answer:
The costal cartilage connects the ribs to the sternum. Costal cartilage normally allows forward movement of the ribs, providing flexibility to the chest wall. There are usually 12 pairs of cartilage associated with the rib cage.

Answer:
4. According to what is observed in the diagram, the maltose (substrate) binds to the maltase (enzyme) to obtain glucose molecules (product), in a process of <u>hydrolysis</u> of the maltose.
5. Three factors that can affect intestinal maltose activity - slowing it down or stopping it - are temperature, pH and substrate depletion.
Explanation:
4. Enzymes, such as maltase, have the function of making a reaction faster and decreasing the activation energy. <u>Maltase is responsible for breaking down a maltose molecule, a dimer, into two glucose monomers</u>, which is a hydrolysis reaction of the bonds that hold glucose molecules together.
5. There are several factors that can cause the decrease or cessation of the activity of an enzyme. <u>Enzymes are activated when substrate is available and work best under ideal temperature and pH conditions</u>. When there are alterations of these factors, the enzyme will reduce or stop the reaction in which it intervenes.
- <em><u>pH</u></em><em>: when the pH increases or decreases it produces a decrease in the speed of reaction that catalyzes an enzyme. Very high or low pH levels can denature the enzyme and make the expected reaction not occur.
</em>
- <em><u>Temperature</u></em><em>: like pH, changes in temperature can slow or stop maltase activity.
</em>
- <em><u>Substrate availability</u></em><em>: It is a fact that when the specific substrate of an enzyme becomes depleted, the rate of reaction slows down, stopping when no substrate is available.</em>
Explanation:
It should be noted that the vegetables at a buffet should be heated to a temperature of about 140°F or above. This is necessary in order to prevent the food from spoiling which is referred to as the temperature danger zone which is when the temperature is lesser and this can result into bacteria growing on the food.
Answer:
the transmission of traits from one generation to the next. These traits can be physical, such as eye colour, blood type or a disease, or behavioural.
