Calorie is a unit of heat
Answer:
According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
Answer:
The correct answer is a. carnivores.
Photosynthesis is the process by which plants make their food from carbon dioxide and water in the presence of sunlight and chlorophyll. Hence, they convert light energy into chemical energy (food or glucose).
This energy is first utilized in the cellular respiration and then the rest in transferred to the primary consumers i.e. herbivores which feed on green plants.
They use this energy in their metabolic processes. The rest is transferred to the secondary consumers i.e. carnivores which feed on the herbivores.
Hence, energy from the photosynthesis indirectly passes to the carnivores via herbivores.
The axons of the olfactory sensory neurons project to the olfactory bulb in the brain. This part is found in the forbrain and is responsible for the sense of smell. Inside this bulb are spheres of tissue that are called glomeruli. They are from the ends of branching axons.
Answer:
The correct option is C. A virus contains RNA or DNA in a protein coat.
Explanation:
Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.
The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.
The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.
