<span>My answer: Mutations are a change in the genetic structure of a chromosome. Chromosomes contain DNA and RNA, and strands of DNA 'codes' if you will, make up a chromosome.
Hope I helped! :D</span>
Answer:
more cell types are needed to perform specialized functions in multicellular organisms
Explanation:
Cells in a multicellular organism differentiate to produce more cells that perform specialized functions. Each cell type in a multicellular organism has special features that enable it to perform a particular function effectively. In plants, cell differentiation occurs at the stem and root. The meristematic cells differentiate into either an epidermal, parenchymal or a vascular tissue depending on location.
Answer:
The Coriolis effect (the deflective force of Earth's rotation) causes air to be deflected to the right of its path of motion in the Northern Hemisphere and to the left in the Southern Hemisphere. ... However, near Earth's surface, friction slows the winds.
Explanation:
The circular folds slow the passage of the partly digested food along the intestines, and afford an increased surface for absorption. They are covered with small finger-like projections called villi (singular, villus). Each villus, in turn, is covered with microvilli.
While rugae is only evident when an organ or tissue deflares or relaxes. The rugae unfolds for increase in volume . Plicae remains folded in the intestinal walls.
Rugae is not associated with the large absorptive surfaces in the small intestine.
