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)
Who proposed that organisms evolved toward perfection and complexity?
Lamark
Who proposed that all organisms evolved toward perfection and complexity?
Lamark
Explain how plants or plant parts grow toward light or grow upward?
organisms
Is it true lamarck proposed that all organisms have an innate tendency toward complexity and perfection?
Yes, it is true
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.
When two or more organisms cooperate they work together toward a goal which benefits all of the cooperating organisms Cooperation can occur between organisms of different species or organisms within?
Cooperation in ecosystems can benefit all parties involved by increasing overall success and survival. It can take the form of mutualism, where both organisms benefit; commensalism, where one benefits and the other is unharmed; or altruism, where one individual sacrifices for the benefit of others. Ultimately, cooperation is a fundamental strategy for organisms to thrive in their environments.
