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.
A colony on an agar plate that is slightly and equally elevated and unbroken would be classified as circular form of colony. These are pinhead colonies which are usually convex on its entire margins. These form of nutrient agar plates are usually<span> raised or elevated and unbroken.</span><span> </span>
Answer:
The Exponential Equation is a Standard Model Describing the Growth of a Single Population. The easiest way to capture the idea of a growing population is with a single-celled organism, such as a bacterium or a ciliate.
Explanation:
Answer:
1. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
2. Answer! A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. I hope it helps! :)
