The answer is mitochondria because mitochondria is involved in cellular respiration.
We must first define these three prominent definitions of species. Biological species concept means that organisms resemble each other because of genes being passed from parent to offspring. Phylogenetic species concept means that organisms resemble each other because they evolved from a common ancestor. Lastly, morphological species concept characterizes species on the structure of their body parts rather than genetic or phylogeny.
In this case, (1) biological species concept is not applicable for extinct species, (2) phylogenetic species concept is based on evolutionary history, (3) morphological species concept relies on similarities in structure, (4) Morphological and phylogenetic species concept accommodates asexual reproduction, and lastly (5) all species concepts are used by scientists in classification.
Trichomes increase the chances of survival for plants living in areas with infrequent rainfall.
If a plant in a very rainy place had trichomes, it would probably adapt and remove them as time passed as they are unnecessary.
A virus structure can be on of the following: icosahedral, enveloped, complex and helical. These viruses can appear to in a shape but a closer, more steady look reveals that they are actually icosahedral.
The correct answer is option C. A leaf growing in full sunlight
The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.
