It’s b chromosomes because the cell nucleus contains the majority of cells genetic material in the form of multiple linear DNA molecules
Answer:
Tissue
Explanation:
A group of similar cells that perform a particular function is called a tissue. Each cell type has special features that enable it perform a particular function efficiently. Each cell is highly specialized. groups of such specialized cells are normally assembled together to form a tissue which performs a specific function like the epithelial tissue, muscular tissue.
Answer:
The correct answer is C
Explanation:
A plant consumes all the oxygen photosynthesis generates. It also uses all the carbon dioxide respiration creates. As a result, no gas exchange takes place with the environment. Bright sunlight – Photosynthesis uses carbon dioxide and makes oxygen faster than respiration produces carbon dioxide and consumes oxygen

Answer:
The correct answer will be option-B
Explanation:
The data collected on the bacterial species in the Yellowstone national park involved:
1. habitat characteristics
2.DNA of bacteria from each population
3. compared with other species of the park
Based on these features, the biologist could apply all the types of species concept like ecological species concept which allows the study of the species from the same niche.
Also, they compared the DNA of the species of the bacteria and compared them which allows to trace the evolutionary patterns and showing the phylogenetic relationship.
Since bacteria do not reproduce by the sexual reproduction, therefore, a biologist cannot apply the biological species concept which states that species can be called species which can reproduce only with the closely rated species only or the individual of the same species.
Thus, Option-B is the correct answer.
Adaption, evolution, variation are all causes of natural selection.
