I think that it is a vacuole located at the centre of a cell
Answer is Chloroplasts have their own DNA.
Chloroplasts and mitochondria are the two cell organelles which have their own DNA. This DNA is separate from the DNA which is found in the nucleus of the cell. The DNA of both chloroplast and mitochondria can replicates and both can undergoes division. The DNA of both organelles produce many proteins and enzymes required for their function.
sorry if its wrong!
The modern taxonomists classified organisms on the general basis of evolutionary, morphological, and genetic traits
Explanation:
- Evolutionary relationships provides the phylogeny of evolutionary ancestors and descendants
- Homologous structures are structures which look the same but perform different functions
, like bones of a human leg compared to bones on a bird's wing
- Analogous structures have different structure but same function like an insect’s and a bird’s wing
- Embryo developmental pattern and similar relationships
- Similarities in DNA and protein sequencing in related organisms
The above basis provided modern taxonomists to classify organisms according to the various disciplines like Genetics, Cytology, Embryology, Physiology, Anatomy and many more.
The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.
<h3>What is Natural selection?</h3>
Natural selection may be defined as the selection of a few individuals from any given population according to their favorable variations.
Disruptive selection occurs when environmental conditions changes in two different directions. Due to which variance increases in population.
Therefore, the correct option is D.
