Gel electrophoresis can tell you the sequence of a particular DNA fragment.
The statement 'gel electrophoresis can tell you the sequence of a particular DNA fragment' is FALSE.
Gel electrophoresis is a technique widely used in molecular biology laboratories to separate DNA and proteins on the basis of their molecular sizes.Gel electrophoresis consists in applying an electrical field through a gel that contains many small pores in which DNA fragments migrate.The interval of time required for the migration of these fragments of DNA is proportional to the molecular size.In conclusion, the statement 'gel electrophoresis can tell you the sequence of a particular DNA fragment' is FALSE.

Global warming affect biodiversity by increasing temperatures mean increased risk of extinction and the correct option is option B.
Global warming has a detrimental impact on biodiversity, primarily increasing the risk of extinction for many species. Rising temperatures disrupt habitats, leading to habitat loss and reduced living space.
Species may struggle to adapt or migrate fast enough to keep up with changing conditions, resulting in range shifts and potential mismatches in ecological interactions.
Additionally, the specific temperature tolerances of many organisms are exceeded, making them vulnerable to heat stress, disease, and other pressures. While some species may exhibit adaptive responses, the overall consequences of global warming on biodiversity are negative, posing significant threats to the intricate web of life on Earth.
Thus, the ideal selection is option B.

Which comparisons of Trial A (no immunity) and
Trial C (50% immunity) did you include in your
explanation? Check all that apply.
After six points of contact, fewer people were
infected in Trial C than in Trial A.
On average, the slope of the graph for Trial C
was less than than the slope for Trial A.
Infection spread at a slower rate in Trial C than
in Trial A.
In addition to the ten immune people, three
nonimmune people did not become infected.
Help!!!!!
Answer:
1.
3.
4.
Explanation:
In trial A, people have no immunity so there are more chances of infection and in trial C, only 50% of people have immunity so chances of infection are less, so infection will spread faster in trial A than trial C.
If compared, trial C will have less infected people than trial A because people in trial A has no immunity and people in trial C have 50% of immunity, so only fewer people will get infected even after six point of contact.
As percentage of immune people (trial C) is 50, so there are equal chances of immunity and non-immunity. there are three reasons of infection that include source, susceptible person and transmission. source and susceptible person can be the reason of infection in some non-immune people but the transmission reason can vary. so, there is probability that three nonimmune people lie under transmission reason and are not coming in contact with infected people, medical equipment or environment, that causes infection and those three people are not getting infected.
Hence, the correct options are 1, 3 and 4.

Create a nucleotide sequence with at least 9 DNA bases. Then, replicate your DNA strand using the appropriate DNA bases.
Answer and Explanation:
We need to create a nucleotide sequence, but first what are DNA nucleotides? They are the monomers of the entire nucleic acid strand of DNA.
DNA nucleotides have 4 bases: adenine (A), thymine (T), guanine (G), and cytosine (C). When pairing bases, A and T always go together and G and C always go together. (An interesting trick to remember this is Apple in the Tree and Car in the Garage.)
To create our own, we can draw up any combination of A's, T's, C's, and G's. I'm just going to arbitrarily write the following:
A A G C T T C G A T C G A C C
We need to pair these up by replicating it (remember A with T and G with C). The new strand will become:
T T C G A A G C T A G C T G G
Finally, we need to transcribe this back into the original format because replication is creating the same copy of something:
A A G C T T C G A T C G A C C

Given the discussion thus far of commensalism and parasitism, would parasitism be an accurate way to describe the relationship between the strangler fig and the cypress tree?
please help me
The relationship between the strangler fig and the cypress tree closely resembles one of parasitism but is not. It is considered commensalism.
Parasitism is when one organism uses another as a host in order to survive, which generated negative impacts for the host, which will usually end in death. The strangler fig uses the tree as a host in order to sustain itself structurally but does not siphon nutrients from the tree or directly kill it, therefore it is not a form of parasitism.
Commensalism is described as a relationship between two organisms, in which the benefits are gained by only one of the members, but neither of the two is harmed in any way.
The relationship between the strangler fig and the cypress tree is best described as commensalism, given that although the strangler fig does eventually cause the tree to die by encircling its roots and not allowing it to grow, it does not kill the tree directly in order to survive.

Which part of a sea star's stomach is extruded out through it's mouth to eat?
Answer:
Cardiac maybe?
Explanation:
explain the importance of understanding the process of evolution.
why is it important to study how species evolve over the time and how does this relate to their changing environments?
Answer:
Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer. Environmental change and isolation of groups of organisms play an important role in evolution. Environmental change is any change in an environment to which an organism must adapt. Change can be gradual, such as when mountains or deserts form, other species die out, or new species evolve.
