Answer:
BbxBb.
Explanation:
If Bb gene is crossed with Bb, the offspring is produced with normal hearing because both the genes are recessive in which the deafness gene hide and the hearing gene is dominant so the offspring can hear sounds clearly. The dominant A gene is responsible for deafness and we can see the offspring BbxBb in which no dominant gene is present. The other three offspring are deaf because of the presence of dominant A gene in their genetic makeup.
Answer:
3 individuals out of 16 are likely to have normal hearing
Explanation:
Available data:
Two diallelic genes cause deafness, A and BDominant allele A causes deafness (AA + Aa)Recessive allele a does not provoke deafness (aa)Dominant allele B does not provoke deafness (BB + Bb)Recessive allele b causes deafness (bb)Cross:

F1) Genotypes:

13/16 Deaf individuals, A-B- + A-bb, + aabb 3/16 not Deaf individuals, aaB-Use your codon chart and tell me what amino acids are coded for by the mRNA sequence AUG CGG UCC GGA
Answer:
Methionine, arginine, serine, glycine
Explanation:
Use a codon chart (attached below) to determine what amino acids are coded for by the strand of mRNA. Remember that codons are groups of three nucleotides in mRNA. So, read the nucleotides in groups of three (just as how they are separated by spaces) and from left to right.
To use this codon chart, identify the first letter representing the first nucleotide in the codon. Then, find the matching letter that's one of the four biggest letters in the middle of the chart. Identify the second letter, then find the matching medium letter in the chart, staying within the section of the first letter as indicated by the lines, and do the same process with the third. Repeat for each codon.
Thus, with this mRNA strand, the amino acids will be methionine, arginine, serine, glycine.

How does Mitosis support the Cell Theory?
Answer: Mitosis occurs when the nucleus of the cell divides into two identical nuclei with the same number and type of chromosomes, followed by cytokinesis when the cytoplasm, for both plant and animal cells, divides, thus creating two daughter cells that are genetically equal and approximately identical in size.

Describe how the mutation has effected the protein coded by this gene?
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.

Explanation:
During protein synthesis, what does mRNA do?
A It strings together two complements RNA strands
B It constructs proteins out of random amino acids
It strings together two complementary DNA strands
D It delivers DNA's instructions for making proteins to the ribosome
Answer:
No direct answer but this might help out a little bit: <3
Explanation:
The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made. During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its base sequence, and uses the genetic code to translate each three-base triplet, or codon, into its corresponding amino acid.
Answer:
D It delivers DNA's instructions for making proteins to the ribosome

Explain the strengths and weaknesses of Lamarck's theory of evolution.
There is no experimental proof of the lamarckism. New organs are not formed in organisms by their wish or requirement. 3.It is not necessary that an the acquired characters transmit into new
Answer:
Weaknesses are traits may stay around for longer that what their needed and Strengths are we adapt to our needs.
Explanation:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.

Which statement explains why the structure of sickle cells differs from normal red blood cells?
A
The gene mutation affects protein synthesis.
B
The gene mutation prohibits DNA replication.
C
The gene mutation inhibits the cell’s ability to produce tRNA.
D
The gene mutation affects the cell’s ability to produce ATP.
Answer:
a
Explanation:
The structure of sickle cells differs from normal RBCs because of the gene mutation that affect the protein structure.
Sickle Cells:
These cells look like a crescent moon. They are unable to transport oxygen. This cause anemia in the patient.
It is an inherited disorder in which point mutation in the lead to the different protein structure. This results in the sickled RBCs.
Normal blood cells are round in shape and able to transport oxygen.
Therefore, the structure of sickle cells differs from normal RBCs because of the gene mutation that affect the protein structure.

Which of the following will most likely decrease genetic diversity?
А increased reproduction
B selective breeding
C mutations
D immigration
Selective breeding dangers reduced genetic diversity can result in certain insects or diseases attacking, which could be quite devastating. Thus, option B is correct.
What is the cause of selective breeding in genetic diversity?Selective breeding can contribute to a large reduction in the genetic diversity of farmed populations, endangering long-term evolutionary progress and limiting populations' ability to adjust to environmental changes.
Unknowingly selecting uncommon illness genes as part of a desirable characteristic might cause difficulties with particular organisms, such as the high prevalence of deafness in Dalmatian dogs.
Genetic diversity is typically reduced by selective breeding, since only a few individuals are employed to produce enormous numbers of offspring. The population's survivability may be impacted by this.
Therefore, selective breeding will most likely decrease genetic diversity.
