The answer is <span>A. presence of cell membranes.
A classification of living things can be based on many different characteristics but a presence of cell membranes is not one of them. <u>ALL living things have cell membranes.</u> So, <u>there could be no classification</u> of organisms with cell membranes and organisms without cell membranes.
On the other hands, based on mode of nutrition, organisms can be classified of autotrophs and heterotrophs. Based on presence of nucleus, organisms can be prokaryotes (without a nucleus) and eukaryotes (with the nucleus). Number of cells is base for classification of living things on unicellular and multicellular.</span>
A Food Chain Without Herbivores and Carnivores. Without the herbivores, the producers would be free to grow. Producers don't need the herbivores or carnivores to make their own food and energy. They are self-sustaining, and they can't exhaust their food source.
And as well as if there are only producers and no herbivores or carnivores then producers grow on continuously and there will not be the utilization of it. so there can't be a food chain without herbivores or carnivores.
The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.
Conifer Leaf.
Microphyll Leaf.
Megaphyll Leaf.
A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.
The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.
I think the answer is ears if Spain is supposed to be spin and war is supposed to be head
They are related because a modern bird has scales on its feet..
