Answer:
В, С, А
Explanation:
The process of clotting is known as the hemostasis which takes place in three steps: the vascular spasm, the formation of a plug of platelets and the coagulation.
In the given question, step B shows the process of vascular spasm in which the vascular blood vessels becomes constricted due to injury. After this, the platelets present in the blood starts accumulating at the site of injury. These platelets stick together and form a plug-like structure at the site of injury.
Later, step A takes place that is fibrin protein present in the blood starts forming a mesh-like structure which does not allow the bleeding and this process is known as coagulation.
Thus, the selected option is the correct answer.
Answer:
B. The chloroplasts will generate less ATP
Explanation:
Photosynthesis, occurs in the chloroplasts of plants. Solar energy is converted into chemical energy in the form of stable carbohydrates.
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process. The thylakoid contains multiple folded membranes called granum stacked together. They contain light-absorbing pigments like chlorophyll.
Here, absorbed light is used in photolysis, to split water produce H+, O2 and high-energy electrons for the high-energy producing electron transport chain.
Protons are pumped into the stroma within granum, producing ATP. ∴ Without ATPase, less ATP is produced.
Answer:
No.
Explanation:
Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms.
Fossils, Land features, climate, etc.

Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
