Answer:
the answer is Arsenic and I'm trying to make this longer cause it has to be more than 20 words lol

Explanation:
The disease sickle cell anemia is caused by homozygosity for a mutation:
Albinism is a recessive trait:
The genes S/s and A/a are linked and separated by 1 map unit.
Remember that 1 mu means that 1% of the gametes produced by an individual will be recombinant.
Son: Sa/sA
The gametes he can produce are:
Since the frequency of recombination is 1% (or 0.01), each recombinant gamete has a frequency of 0.005 (since there are two possible recombinant gametes).
The parental gametes will appear with a frequency of 0.99, each of them with a frequenct of 0.495.
Daughter: SA/sa
The gametes she can produce are:
In order for them to have an albino child with anemia (sa/sa), the gamete sa from each parent had to be produced and fused into the zygote. Since the production of gametes by each parent is an independent event, the probability of having sa/sa offspring can be calculated as:
Prob. sa gamete son × Prob. sa gamete daughter = 0.005 × 0.495 = 0.0025
The probability that a child of theirs will be an albino with sickle-cell anemia is 0.25%
O a reaction

Answer:
these statements are true
B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence
D) Missense mutations always change the amino acid sequence encoded by a gene
E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.
Explanation:
B) insertion or deletion of nucleotide in coding region of DNA can change the amino acid sequence encoded.
D) missense mutation means that the change in nucleotide sequence resulting in change in amino acid sequence encoded by gene.
E) A mutation may alter the promoter of a gene, thereby affecting the rate of transcription.
The correct statements regarding single base pair mutations are: insertions or deletions within a protein coding sequence likely change the encoded amino acid sequence; missense mutations always change the encoded amino acid sequence; nucleotide substitutions outside of the coding sequence can impact gene expression.
Your question focuses on single base-pair mutations and their functional consequences. After considering the provided statements, the three correct answers are: B) Insertions or deletions of single base-pairs within a protein coding sequence probably change the amino acid sequence encoded by a gene. D) Missense mutations always change the amino acid sequence encoded by a gene. E) Nucleotide substitutions outside of the coding sequence can affect the expression of a gene.
A missense mutation is a type of mutation where a single base pair is changed, leading to the substitution of a different amino acid in the resulting protein. This change can alter the function of the protein. On the other hand, insertions or deletions of single base-pairs can often lead to a frameshift mutation, which alters the reading frame and potentially changes every subsequent amino acid in the encoded protein, often resulting in a nonfunctional protein. Lastly, nucleotide substitutions outside of the coding sequence can also affect gene expression by changing areas involved in the regulation of gene transcription.

The absolute zero is the temperature at which molecular motion ceases i.e translational kinetic of molecules become zero, but the molecules possess the potential energy, according to the Kinetic theory of gases. Thus, the absolute zero is not the zero energy temperature.
Parasitic
Competition
Mutualism
Answer: Comensulism
Commensalism is being displayed From the video Clownfish and Sea Anemone Partnership
Explanation:
From the video Clownfish and sea Anemone Partnership there is a significant relation that can be seen from the statement itself too and that is sign of symbolism.
The relation of symbol is used for the sea anemone. So, both Clown fish and Anemone are held to be very beneficial whenever these two fishes are kept together in presence of each other.
So, it can be said clown fish and sea anemone have a very deep relation between each other.
Answer:
C
Explanation:
Hydrophobic interactions are the result of strong attractions between nonpolar regions and are crucial in biological phenomenon such as protein folding and cell membrane structure. The correct option is D.
Hydrophobic interactions often occur between nonpolar molecules or groups. The correct statement among those provided is D: hydrophobic interactions are the result of strong attractions between nonpolar regions.
These interactions do not require the presence of surrounding water molecules, nor do they result from maximizing contact with water. Instead, nonpolar molecules or groups tend to gather together, or aggregate, to minimize their exposure to water or any other polar substances.
This is because there is a natural repulsion between polar and nonpolar substances. Thus, hydrophobic interactions are critical for the folding and stability of proteins, cell membrane structure, and many other biological phenomena. The correct option is D.
