For number one I’m guessing 35% because for transportation it says 35 and bus is transporting/transportation.
Answer:
e. Researchers suspect that portions of the reverse cycle may have been responsible for fixing CO2
Explanation:
Carbon fixation refers to the metabolic process by which inorganic carbon, especially carbon dioxide (CO2), is converted to organic matter. Moreover, the citric acid cycle (TCA) is a metabolic pathway capable of generating energy by the oxidation of acetate (which is derived from carbohydrates, fats, and proteins) into CO2. The reverse TCA cycle is a form of carbon fixation that uses CO2 and water molecules to produce organic carbon molecules. The enzymes that are unique to the reverse TCA cycle include ATP citrate lyase (required to cleave citrate into acetyl CoA and oxalacetate); 2-oxoglutarate:ferredoxin oxidoreductase (OGOR); and pyruvate ferredoxin oxidoreductase (required for pyruvate decarboxylation/oxidation).
During human gestation, rudiments of all organs develop in the first trimester.
<h3>What is the first trimester?</h3>
- Most people (including your doctors and midwives) divide a full-term pregnancy, which lasts about 9 months, into three 'trimesters'.
- The first trimester of pregnancy is measured from the first day of your last period to week 12, even though you are pregnant from the moment of conception, when a male sperm fertilizes your ovum (egg), when you become pregnant.
- This is so that the majority of women who conceive naturally won't be aware of the conception date.
- Because the changes that occur to you and your unborn child fall into the three general categories of early, middle, and late pregnancy first, second, and third trimesters are a useful way to think about pregnancy.
