Answer:
Memory cells are specalised types Nerve Cells .
Answer:
Both electron transport and a proton gradient
Explanation:
The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.
Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.
Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.
Thus, the selected option is correct.
Answer:
A gamete containing an extra chromosome is formed.
Explanation:
Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.
Scientists classify rocks based on texture, composition, and how the rocks formed.] Rocks are classified by how they formed.
Answer:
Fungi most fungi produce cellulases.
Explanation:
Fungi are eukaryotic microorganisms, however unlike other eukaryotes. Their cell wall is made up of chitin instead of cellulose.
Chitin is a fibrous polysaccharide found in the exoskeleton of arthropods and the cell wall of fungi. where as cellulose is also a polysaccharide which is an important structural component of plant cell wall.
Since fungi are saprophytic they produce enzymes such as cellulases that will help in breakdown of cellulose for food.
They cannot have a cell wall made of cellulose.
