Answer:
Part A: Proteins are made from amino acid monomers. There are 20 different types of amino acids which make up all the proteins of the body. The amino acids are made up of a carbon atom which is joined to an amino group, a carboxyl group and a variant group, known as R. Nucleic acids are made up of 5 carbon sugar, phosphate group and nitrogenous bases. Hence, nucleic acids are made up of nucleotides.
Part B: Protiens are important molecule which carry out various functions of the body. They are involved in regulation of various body process. Some proteins are involved in the transportation of various molecules. Other type of proteins are involved in various immune functions and hence protect the body. For example, antibodies are proteins which defend the body against pathogens.
Nucleic acids are involved in the storing and expressing of genetic information. They also direct the body for protein synthesis.
Enzymes are also known as Biological catalysts. An enzyme working at its maximum possible rate, where the substrate concentration is in excess is <span>V max.
</span><span>The reaction is slow because the molecules are moving slowly and they will not often collide with the active site of an enzyme, so the binding of an enzyme and substrate is rare.</span>
Answer:
Yes they do.
Explanation:
Both plant and animal cells contain ribosomes. Some may be found floating in the cytoplasm while others may be found in the rough Endoplasmic Reticulum.
Answer: CO alarms have a life expectancy of around seven years. The CO alarm will beep every 30 seconds or display ERR or END. If a CO alarm is at its end-of-life, replacing the battery will not stop the beep. Most detectors will beep 4 or 5 times in a row about every 4 seconds. Do not mistake dangerous levels of poisonous gas for a detector with low battery.
Explanation: (credits to the internet) Hope this helped! :D
I would say B) <span>The shoot is positively phototropic and negatively gravitropic; the root is positively gravitropic and negatively phototropic.
This is because the shoot of the plant is attracted towards the sun, as the chloroplasts in the leaves need sunlight to make food. As well, the roots are attracted downward to absorb more water and minerals from the sun.
