Answer:
When many molecules of a simple compound join together, the product is termed a polymer and the process polymerization. The simple compounds whose molecules join together to form the polymers are called monomers. The polymer is a chain of atoms, providing a backbone, to which atoms or groups of atoms are joined.
Answer:
A. 60 grams protein
B. 74 grams of protein
Explanation:
The amount of protein needed depends on weight and lifestyle. The daily minimum recommended by the National Institutes of Health is 0.36 grams per pound for a sedentary person. But the daily optimal intake for this same sedentary person is 0,8 grams of protein per kg of body weight. On the other hand hand, adults with a more active lifestyle need more protein in their body, the intake should be between 1,2 and 2,0 grams of protein per kg. For example, endurance runners need up to 1,4 and strength training athletes need up to 1.8 g of protein per kg.
The first step for calculating protein requirements is calculate the weight in kilograms, so we need to divide the weight in pounds by 2,2.
154lb/2,2= 70 kilograms
Then we have to multiply the weight in kg, times the number of protein needed per day, 0,8 for a sedentary healthy adult.
70kg x 0,8= 56 grams
Part A:
165-pound (lb) male who is healthy but sedentary
165 lb/2.2 = 75 kg
75 kg x 0,8 = 60 grams protein per day
Part B. Sarah is moderately active so we need to use a number between 1,2 and 2, since shes active but not very active we can use the 1,2.
136-lb/2,2= 62 kg
62 kg x 1,2 = 74 grams of protein
Explanation:
B. Lactic acid is produced from lactobacilli as the starter undergoes fermentation
Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate (pyruvic acid) is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation. In lactic acid bacteria, the pyruvate produced is directly transferred to lactate (a form of lactic acid) producing NAD+.
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).
Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.
This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...
- Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
- The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
- The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
Within cells, aerobic respiration may not occur due to several factors:
- - a lack of inorganic, final electron acceptors
- -incomplete or lack of a complete electron transport system
- -missing genes for enzymes within the Kreb's cycle

Because the lower levels of the food chain have the most energy so more organisms can be sustained, but as you go up the food chain, less and less energy is transferred so less organisms can survive
Answer: genotypic ratio 2/4
Phenotypic ratio 4/4 is the same
Explanation: suppose RR is the dominant female and Rr is the heterozygous male. Then after the cross genetically 2 have RR and 2 have Rr ratio. But phenotypically all 4 are the same.
