D. Organisms only need water
Adaptation is supported by Darwin's observation of local
variation among tortoises in the Galapagos Islands.
<span>In biology, an </span>adaptation, also called an adaptive trait, is a trait with a
current functional role in the life of an organism that is maintained and
evolved by means of natural selection. Adaptation<span> refers
to both the current state of being </span>adapted<span> and
to the dynamic evolutionary process that leads to the </span>adaptation.
The correct answer between all
the choices given is the second choice or letter B. I am hoping that this
answer has satisfied your query and it will be able to help you in your
endeavor, and if you would like, feel free to ask another question.
The ileum has <span>plicae circulares</span>, villi and microvilli, that are folds and projections of the mucosa layer of the ileum, that increase the surface area of food absorption. The mucosa and the submucosa of the stomach have inner folds called rugae that increase the surface areas in which food is digested by enzymes.
Plants have root hairs in their tap roots that also increase the surface area for which they absorb water and nutrient from the soil. Fibrous roots have a mesh-like a network that also increases the surface area for increased absorption.
Answer:
D&B
Explanation:
Each chromosome contains a single double-stranded piece of DNA
one chromosome contains thousands of genes
1. anaphasespindle fibers pull back to the centromeres separating the sister chromatids, 2 sets of chromosomes are present
2. interphasecell grows, DNA is copies, organelles replicate
3. metaphasechromosomes line up in the middle of the cell on spindle fibers
4. telophasenuclear envelope forms, chromosomes unwind, spindle fibers dissolve
5. prophase chromosomes are visible, nuclear envelope breaks down, spindle fibers from between centrosomes
