C coz asexual means no mixing gametes between male and female parents. Child and parent is GENETICALLY IDENTICAL. can be found in plants. Examples include rhizome and bulbs.
Sexual reproduction involves both sex and two (haploid) gametes produce one (diploid) zygote
Inbreeding reduce genetic diversity coz parents of similar gene sequence produce offspring. Never lead to genetically identical offsprings because of crossing over of non-sister chromatids in meiosis I, random assortment of chromosomes in meiosis I, random fusion of sperms and eggs during fertilisation and mutations.
Selective breeding does not interfere directly with gene contents, only select individuals with preferable traits for reproduction to increase the chance of producing offsprings with said traits. Other traits of parent and offspring could be different.
Microtubules are macromolecules that build both, cilia and flagella.
<span>Microtubules are cytoskeletal fibres that are formed by polymerization of α,β-tubulin and they are important components of cilia, flagella and some other cellular structures. Cilia and flagella are very similar in their organization, both have a central bundle of microtubules-axoneme. Axoneme is compound of nine outer doublet microtubules which surround a central pair of singlet microtubules. Even thought cilia and flagella are structurally similar, they are differentiated based on their function and/or length. Flagella are longer and the primary role of the flagella is locomotion. On the other hand, shorten cilia often has the function in sensing the extracellular environment.</span>
Facillatated diffusion is faster than simple diffusion when solute concentration is low because it uses channels to transport molecules throught the lipid bilayer. Simple diffusion depends upon concentration gradients so the net movement of diffusing molecules depends on the concentration gradient, thus the rate of diffusion is directly proportional to the concentration gradient.
