Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
Answer:A. club
Explanation:
Fungi are eukaryotic organisms .they are feed on dead, decaying matter because they lack chloroplast. Most fungi are parasitic or symbiotic.
Fungi lacks root, stem and leaves. They however posses threadlike filaments called hyphae, which forms a larger mass called mycellium. Fungi reproduce asexually by spores. The classification of fungi are;
#zygomycetes, also called conjugation fungi .eg bread mold
#ascomycetes, also called sac fungi eg baker's yeast
#deuteromycota, also called imperfect fungi eg penicillium
#basidiomycetes .they are the commonly known mushrooms. They grow on wood and trees. Most of their species are edible. They are also called club fungi

Electronegativity.
If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.
Answer:
When Darwin formulated the theory of evolution through ____THE PINZONES________ ____________, he used changes he saw in the __________ OTHER SPECIES OF THE GALAPAGOS ISLANDS______________ to support his assertions. However, there are other pieces of evidence that demonstrate the occurrence of evolution in living things.
Explanation:
Charles Darwin analyzed the evolution of life or living beings through a species of birds that are called finches, also to reinforce this theory he analyzed other species on the Galapagos Island where these finches were, and noted that the turtles were from larger and the rest of the species also presented some differences, this is how their theory reinforces and drives it, indicating that the one that survives is the most suitable for that particular environment.
