Which of the following statements about the cytoskeleton is incorrect? A. The dynamic aspect of cytoskeletal function is made po
ssible by the assembly and disassembly of a few simple types of proteins into large aggregates. B. Microfilaments are structurally rigid and resist compression, while microtubules resist tension (stretching). C. Movement of cilia and flagella is the result of motor proteins causing microtubules to move relative to each other D. Transport vesicles among the membranes of the endomembrane system depend on the function of the cytoskeleton.
Microfilaments are the thinnest filament of the exoskeleton and they are found in the cytoplasm of eurkaryotic cells. The polymers that made up the microfilament are flexible and strong and they provide support for the cell.
Resource partitioning refers to differences in resource use
between species regardless of the origin of the differences. Similar species
can coexist in the same ecological community without one pushing the others to
extinction through competition. Species compete for the same resources which
include nutrients and habitats which are the raw materials needed by organisms
to grow, live, and reproduce. For the question given above, the divergence in
lizards is an example of resource partitioning.
Tarbuck, Earth's crust is made up of several elements: oxygen, 46.6 percent by weight; silicon, 27.7 percent; aluminum, 8.1 percent; iron, 5 percent; calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent
About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which all together constitute the hydrosphere.

Earth.
Almost 99% of the minerals making up the Earth's crust are made up of just eight elements. Most of these elements are found combined with other elements as compounds.
Answer: B Explanation: Most mammals have only one pair of sex chromosomes in each cell. Males have only one Y chromosome and one X chromosome, while females have two X chromosomes. In Mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development in a male.
