Some characteristics that is shared is a soft body and an outer shell to protect their body.
Freshwater marshes occur beside rivers and oceans.
Yes, this statement is true .
Freshwater marshes conatins fresh water . They are generally found near the river mouths. They are found along the fringes of lakes and rivers where the water table, the upper surface of underground water, is very high. Marshes are useful for the damage cause by the flood storing the water.
Answer:
D Flow of protons across an electrochemical gradient
Explanation:
The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.
In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.
The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.
Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.
Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
The correct answer is: B) flesh of another animal
The shape of teeth is tightly connected with the food that animal eats.Examples:
• Herbivores (plant eaters) have flat teeth specialized for the grass chewing.
• Carnivores (flesh eaters) have long and sharp teeth for meat cutting.
• Omnivores (eat meat and plants) such as humans have various types of teeth with different functions.
There are four main types of teeth: incisors (at the front, sharp for cutting), canines ( to grip and tear food), premolars (flat surface for food crushing), molars (the biggest with flat biting surface, to chew).
