Answer: A
Explanation:
The nucleus provides the instructions for making the proteins (the DNA) and the ribosomes are actually where the proteins are made.
Answer:
The answer (Image 1) is attached. Since the options weren't provided, I've attached the image of the options, too.
Explanation:
The plasma membrane is composed of phospholipids, a special form of lipids with a hydrophilic head and hydrophobic tail. According to the fluid mosaic model, the hydrophilic heads are positioned towards the outside where they freely interact with the extracellular matrix and cytosol. Whereas, the hydrophobic tails are positioned towards the inside so they aren't exposed to water.
Liposomes are lipid bases particles used for drug and vector delivery. The picture shows a typical liposome.
In the current case, for water to move both outside and inside, hydrophilic heads should be present inside as well as outside the tails.

Hope I’ve helped ;)
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.
