The answer is; B
Mutations change the order of nucleotide and therefore affects codons that code for proteins. A different protein is thus produced from the wild type hence creating variations. Genetic shuffling in sexual reproduction, also called gene recombination occurs during meiosis and also when different organisms exchange genetic material such as in bacteria.
The correct answer is A. Decline in vision
Explanation:
The term "middle age" is used to describe the time span between 45 and around 65 in human life. During this, important changes occur in terms of senses, this age usually implies a decline in senses including pain, taste, smell, and vision. In terms of vision, it is common during middle ages people began experiencing blurring vision or weakened vision as during this age conditions such as presbyopia, glaucoma, cataracts, among others. Additionally, the decline in vision in this age is commonly related to other conditions such as diabetes, the use of medicines and also jobs that are visually demanding. Thus, in middle age, people commonly experience a decline in vision.
Answer:
The correct answer will be options
1. Process includes glycolysis.
2. Between 2 and 38 ATP are produced per molecule of glucose input .
3. Much or most of the ATP produced is produced by oxidative phosphorylation.
4. Process involves electron transport and chemiosmosis.
5. End products are CO₂ and H₂O.
6. Process involves the Krebs cycle.
Explanation:
Cellular respiration is the oxidative process which involves the breakdown of food molecules like glucose, amino acids and fats to release heat and energy in the form of ATP.
In the presence of oxygen or aerobic respiration it undergoes four stages: glycolysis, link reaction, Krebs cycle and electron transport chain while in the anaerobic reaction it produces ethanol and carbon dioxide by the process of fermentation.
Each stage produces energy in the form of ATP molecules or co-enzymes NADH OR FADH₂ like glycolysis produces 2 ATP and link reaction, Krebs cycle produces NADH OR FADH₂ in addition to ATP. Each NADH produces 3 ATP while Each FADH₂ produces 2 ATP during electron transport chain. So, ATP molecules are produced between 2 to 38 ATP molecules in each stage with large number during electron transport chain from these co-enzymes.
The waste products produced in the stages of cellular respiration are CO₂ molecules and H₂O which is also known as metabolic water.
It’s C. Amino acids bind to CCA3’OH end of tRNA via ester bond.
