Correct answer: C) Nutrients are circulated throughout the biosphere
Biogeochemical cycles are cycles by which essential elements of a living organism are circulated continuously. It consider the biological, chemical, and geological aspect of each cycle.
The most important biogeochemical cycles are nitrogen cycle, carbon cycle, water cycle, oxygen cycle and phosphorous cycle.
Biogeochemical cycle always have a state of equilibrium, and the state of equilibrium is attained when there is balance in cycling of element among the compartment.
Those would be oceans and lakes. Hope this helps and have a nice day!
Also viruses have nucleic acid whether DNA or RNA nucleic acid, they are so minute that you can't observed them,
it's letter C, they are also responsible for proteins. their cell wall is made up of capsid.
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
The correct choice from given option is "D", "Lactobacillus"
It seems proper to explain a bit about the types of cells here. Two type of cells are:
1) Prokaryotic: these cells have no nucleus and they are small and simple.
2) Eukaryotic: These cells have a nucleus and are large and complex as opposed to prokaryotic.
"Lactobacillus" belong to first stated category here.
