Answer:
The answer is "inflorescence, oak"
Explanation:
- An inflorescence is a flower group, which are clustered nearby in a stalk, which is also known as the peduncle. In lily, the individual flower was found, not quite as groups. However, the flowers are set as an inflorescence in the oak tree.
- It refers to a group or community of a flower cluster borne on a flower, which is traditional flowers of oak are called catkins, that's why 'inflorescence, oak' is the reaction.
Answer: Enzymes are proteins that catalyze, or affect the rate, of chemical reactions without themselves being altered in the process. Specific enzymes catalyze each cellular reaction. The main role of enzymes during the respiration reaction is to assist in transferring electrons from one molecule to another.
There are two types of inhibitors; competitive and noncompetitive inhibitors. Competitive inhibitors bind to the active site of the enzyme and prevent substrate from binding.

Answer:
Sequential or integrated screening
Cell-free fetal DNA testing
Proteins in your blood that can mean your baby has a higher risk of birth defects
Explanation:
Sequential or integrated screening
Sequential screening is a test that uses a mix of ultrasound and blood tests to look birth defects at 10 and 13 weeks of pregnancy.
Integrated screening is similar and is done at around 12 weeks and is slightly more accurate
Cell-free fetal DNA testing is testing the baby's DNA that ends up in the mothers blood for signs of birth defects

Answer:
Preservatives are the chemical substances which are added to the products like pharmaceuticals, paints, biological samples, foods and many other products to prevent the disintegration or rotting mainly caused by the growth of microbes or due to undesirable chemical changes.Preservations are of 2 types i.e. chemical & physical. Chemical preservation means addition of chemical compounds to the products. Physical preservation means process such as refrigeration & drying. Preservatives aims at decreasing the risk of foodborne infections, reduce microbial spoilage & to improve nutritional quality. Some physical methods used for food preservation include dehydration, freeze drying, refrigeration & UV-C radiation. Chemical And physical preservation are sometimes used in the combination.
The advantages of using the food preservatives are:
- Decrease the moisture content
- Increase the acidity
- Preventing the ripening process( naturally)
- Acts as an antioxidant
- Lowering the food waste
Main properties of ideal preservatives :
- It should not be poisonous
- It should not be irritant
- It should have physical as well as chemical stability
- Preservative must maintain the good compatibility with other ingredients used in the process of developing food
- It should acts as preservative in small concentration
- It should retains activity through food manufacturing, shelf life & usage
