Answer;
Chromosomes
Depending on the organism, the number of chromosomes in a cell may change.
Explanation;
When a cell in the body divides, it will pass on a copy of its DNA to each of its daughter cells. DNA is also passed on at the level of organisms, with the DNA in sperm and egg cells combining to form a new organism that has genetic material from both its parents.
Each species has its own characteristic number of chromosomes.Humans, for instance, have 46 chromosomes in a typical body cell (somatic cell), while dogs have 78. Like many species of animals and plants, humans are diploid (2n), meaning that most of their chromosomes come in matched sets known as homologous pairs.
Answer:
Explanation:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.
Stomata
All plant leaves need to breathe. The exchange of atmospheric gases is essential to photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into oxygen and fuel. Openings called stomata make this possible.

My answer would be "Earthquakes happen along cracks in the earth's surface, called fault lines, and can be felt over large areas"
