Answer:
True
Explanation:
Our genetic material (DNA) is made up of sequences of nucleotides. These nucleotide sequences undergo changes from time to time either naturally or induced by mutagens (mutation-causing components). These changes that occur are called MUTATIONS, and they produce varying effects on the organisms's they occur in.
A mutation may affect a single nucleotide (point mutation). This can lead to three kind of effects, one in which has no effect on the sequence and subsequently on the organism. This is possible due to the degenerate nature of the genetic code, as more than one codon specifies a particular amino acid. The change can occur in such a way that the codon that arises codes for the same amino acid as the original codon. This is called a SILENT mutation and in this case, there is no effect on the organisms.
In another case, the mutation can change the amino acid sequence entirely leading to the formation of a different non-functional polypeptide. This could be very lethal as a deficiency of the original polypeptide could cause serious harmful effects to the affected organism. This is called MISSENSE mutation.
Also, the mutation can add or insert nucleotide(s) to the sequence in such a way that it produces a protein that is beneficial to the organism. An example is the antibiotic resistance that mutation confers upon certain bacteria species.
Biodegradation is the process by which organic substances are naturally broken down by living organisms.
It is the disintegration of organic substances that are broken down by microorganisms. Bacteria, fungi and other microorganisms transform the compounds into simpler substances.
Answer:
Yes, it is correct, but you should also specify that B stands for black and b stands for gray, it is also important to mention the characteristic in order to have full information.
Answer:
Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length
Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length
The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).
The inference procedure uses the information collected from the sample in order to obtain one conclusion. Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
NNN all this math gon make me act up
