Answer: Sterilization refers to any process that eliminates, removes, kills, or deactivates all forms of life (in particular referring to microorganisms such as fungi, bacteria, viruses, spores, unicellular eukaryotic organisms such as Plasmodium, etc.) and other biological agents like prions present in a specific surface, object or fluid, for example food or biological culture media. Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present. After sterilization, an object is referred to as being sterile or aseptic.
Explanation:
Answer:
d) diploidy
Explanation:
PKU is a genetic condition caused by changes in genes and are transferred through generations in a recessive inheritance pattern. PKU is caused by mutations in the gene PAH phenylalanine hydroxylase (PAH) which codes for an enzyme (type of protein) called phenylalanine hydroxylase. PKU is caused by an Autosomal recessive pattern i.e A person must have a mutation on BOTH of his/her two copies of the PAH gene in order to have PKU and this only occurs if both parents are carriers for PKU.
Now , What maintains the presence of this harmful allele(The recessive allele that causes phenylketonuria (PKU)) in a population's gene pool?
NOTE the word recessive!
The answer is Diploidy.
This is because, the term diploidy refers to a state of having two sets of the chromosomes (and therefore two copies of genes), especially in somatic cells. Therefore, the usefulness of this is to stabilize the chromosome if one of the chromosome(i.e one copy of the gene) is a carrier of PKU.
Acetyl CoA is used to synthesize fatty acids, which then bind with glycerol to form triglycerides.
Fatty acid synthesis is the process that occurs in the cytoplasm of the cell from acetyl-CoA and NADPH. The enzymes that perform the process of synthesis are called fatty acid synthases. Acetyl-CoA is derived from carbohydrates via the glycolytic pathway (through glycolysis). Glycerol is also derived from the glycolytic pathway and it combines with three fatty acids to form triglycerides.
Explanation:
They break down the plants and animals they eat
this is because, plants absorb carbon from the atmosphere to grow in the process of photosynthesis, then consumers obtain their food from plants hence obtaining carbon
