Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related.
Antibiotics that kill large numbers of gram-negative bacteria are primarily aminoglycosides and some higher generation cephalosporins. The major medical concern in antibiotic usage is antimicrobial resistance which can arise with improper use of antibiotics. On the other hand, higher generation antibiotics that are proven bactericidal can have more detrimental adverse effects for the patient.
Answer:
B
Explanation:
The folds contain ribosomes attached to the membrane. The more the folds the more the surface area to which more ribosomes can attach. The ribosomes are organelles responsible for the manufacture of protein in cells. Thereafter, the proteins are properly folded by the mediation of chaperones in the lumen of the RER.
Answer:
All cells all the time.
Explanation:
Photosynthesis is the process of the formation of organic nutrients, glucose in the presence of sunlight by fixing CO2. Cellular respiration is the oxidation of nutrients. The process forms ATP which in turn serve as energy currency for living cells.
Plant cells perform cellular respiration to obtain the energy stored in the chemical bonds of glucose. The energy obtained by cellular respiration is used to perform the vital functions by cells. Therefore, irrespective of photosynthesis, cellular respiration occurs in all the cells of the plants all the time to fulfill the energy requirement for growth and development.
