Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)
What is a sentence for the word phototropic?
a flower is phototrophic because it is moving toward the sun
What type of response involvesWhat type of response involves an organism moving to or from the earth an organism moving to or from the earth?
The type of response that involves an organism moving toward or away from the Earth is called a geotactic response. Organisms exhibiting positive geotaxis move toward the gravitational pull, while those showing negative geotaxis move away from it. This behavior helps organisms orient themselves in their environment, facilitating activities like foraging and nesting.
Which are the first organisms to start the process of primary succesion?
The first organisms to initiate primary succession are typically pioneer species, such as lichens and mosses. These organisms can colonize bare rock or barren landscapes, breaking down the substrate and creating soil as they grow and decompose. Over time, this process allows for the establishment of more complex plant species, leading to a gradual progression toward a more diverse ecosystem.
2 examples How living things respond to changes in their enviorment?
Living things respond to changes in their environment through various adaptations and behaviors. For instance, plants may grow toward light sources through a process called phototropism, ensuring they receive adequate sunlight for photosynthesis. Similarly, animals might migrate in response to seasonal changes, such as birds flying south for warmer temperatures and food availability during winter months. These responses help organisms survive and thrive in their specific habitats.
Why do certain dyes migrate toward the cathode and others towards the anode?
Molecules migrate to different electrodes depending on the charge they carry. Positively charged dyes migrate toward the anode (the negative electrode) and negatively charged dyes migrate toward the cathode (the positive electrode)

What organism uses taxis?
Taxis is a directed movement toward or away from a stimulus, commonly observed in various organisms, particularly in single-celled organisms like protozoa and bacteria. For example, E. coli bacteria exhibit chemotaxis, moving toward higher concentrations of nutrients and away from harmful substances. Additionally, many insects, such as moths, demonstrate phototaxis by moving toward light sources. These movements help organisms navigate their environments effectively.
What is a positive chemotactic response?
A positive chemotactic response refers to the movement of cells or organisms toward a higher concentration of a chemical attractant in their environment. This process is crucial for various biological functions, including immune responses, where immune cells migrate to sites of infection or inflammation. It plays a key role in development, wound healing, and the functioning of the nervous system, where cells navigate toward signaling molecules. Positive chemotaxis enhances the organism's ability to respond effectively to environmental cues.
What scientist proposed that all organisms evolved toward perfection and complexity?
Jean-Baptiste Lamarck proposed the theory of evolution known as Lamarckism, which suggested that organisms evolve toward perfection and complexity through the inheritance of acquired traits. This theory has been largely discredited in favor of Charles Darwin's theory of natural selection.
What are four problems farmers face in the Bahamas?
lack of fertile soil poor transportation to market uneven distribution poor atitude toward farming looked down upon by locals
Where do buffalo roam?
American bison migrate from Mexico up to central U.S., From california to Northern U.S., From central U.S., to the New York region, and in rare circumstances from central U.S. to the South-East
How do the birds spent the winters?
Well, depends on which continent. In the United States, they migrate toward the southern states; Florida, Texas, North Carolina, South Carolina, Virginia, \etc./ Hope I helped! -Kalyn- :)
In gel electrophoresism DNA fragments migrate toward one end of a gel because that are?
In gel electrophoresis, DNA fragments migrate toward one end of a gel because they are negatively charged and are attracted to the positive electrode at the opposite end of the gel. The smaller DNA fragments move faster through the gel matrix while the larger fragments move more slowly.
