The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
2 examples -
1.) in italy, ( limone ) a unique mutation protects them from developing atherosclerosis,
2.)theres mutation in bacteria too, this mutation allows bacteria to survive in the presence of antibiotic drugs, leading to the evolution of antibiotic-resistant strains of bacteria.
Answer: Option B) a lipid molecule that contains at least one carbohydrate unit.
Explanation:
A glycolipid is a membrane lipid molecule with a short carbohydrate chain attached to a hydrophobic tail by a glycosidic bond. Examples of complex glycolipid are cerebrosides found in the brain
I feel like the answer would be A because photosynthesis gives off energy and they don’t produce glucose
Answer:
Yes, glucose expel out of the body through urine, if the concentration of glucose is high in blood.
Explanation:
Glucose is monosaccharide which is used by the body for the production of energy in the form of Adenine tri phosphate. This glucose is stored by the body in the form of glycogen when its concentration is high. If glucose level is very high than optimal level in the blood so the kidney send it to the urine for the removal from blood.
