Starting at least level up to the largest as organized by ecologists, see the chart below.
Answer: option C) species -> community -> biosphereD
Explanation:
Species refers to closely related organisms (plant or animal). When different species of organisms live together in a habitat where they feed on one another and become codependent on one another, a COMMUNITY has been formed.
A BIOSPHERE, however is composed of many ecosystems i.e different species of plants, animals and microorganisms relating with their environment. Thus, a biosphere = Communities + environment
I wish you added the diagram but I can tell that the long strings are the spindle fibres.
Answer:
Structure X is only found in plant cells, and structure Y is found in plant and animal cells.
Explanation:
The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.
Structure X is not living, and structure Y is living. - this is false, both animal and plant cells are living.
Structure X can be found in some human cells, and structure Y can be found in some plant cells. - this is false, the opposite is true.
Structure X is only found in plant cells, and structure Y is found in plant and animal cells. - this is true structure X is the plant cell wall, and structure Y is the cell membrane
Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
Answer:
The introns of protein-encoding nuclear genes of higher eukaryotes almost invariably begin (5') with GT and end (3') with AG. In addition, the 3'subterminal A in the “TACTAAC box” is completely conserved; this A is involved in bond formation during intron excision.
