Answer:
cell walls made of chitin
Explanation:
Fungal cells differ from mammalian cells in that they have cell walls that are composed of chitin, glucans, mannans, and glycoproteins. Both mammalian and fungal cells have cell membranes; however, they differ in their lipid composition.
A karyotype is the number and appearance of chromosomes in the nucleus of an eukaryotic cell. Karyotypes also describe the chromosomes count of an organism and the appearance of these chromosomes under the microscope. Cell which lack cell cycle control are often cancerous cells and they look different under the microscope compared to the normal cells. Cancerous cells will look different under the microscope in term of number of chromosomes, size, length, positioning and general appearance.
Answer:
<u><em>Galapagos finches</em></u><u> have various beak sizes that make foraging for food more successful.</u>
Explanation:
Organisms evolve over time due to changes in their genome. These are pontaneous, and occur in DNA at random. These changes are called mutations and form alleles or different forms of a gene.
Over time within a population, the number alleles increase the variation of the population. These variants may confer specific traits within an individual, that may confer a biological advantage.
Thus, the trait may make the organisms more capable of obtaining food, shelter a mate etc. or ensure survival, i.e. they are able to pass on their genes to the next generation.
