Answer:
Parasitism.
Explanation:
Parasitism is an association in which one organism, lives on another, the host, deriving benefit from it and causing harm to it.
The tapeworm here is a parasite and it lives inside the cat's(host) body where the tapeworm is specialized for its mode of life. It survive and reproduces very well without needing another specie because it is a hermaphrodite. It causes loss or poor development of unwanted organs such as the digestive, sense organs and muscles. Its long flattened body also provides a large surface area for absorption of nutrients too.
The answer to this is C because humans don't have cell walls and if you are looking at an onion it has a cell wall because it is a plant.
Chromosomes, which contain DNA, have several functions. All BUT ONE of these statements is a function of chromosomes. A) Chromosomes determine the traits of an organism. B) Chromosomes provide instructions to make proteins.
They are capable of dividing and renewing for Long periods of time They are unspecialized and they can give rise to speacialized cell types
Macroevolution can cause significant changes in the frequencies of alleles, that can ultimately result in speciation (forming of new species).
Various large-scale events like climate change and continental drift can greatly influence the distribution of species and adaptive radiation of different groups that can fill vacant ecological niches.
The changes in gene regulation and genetic mutations can also contribute to macroevolution by producing novel traits and adaptations.
