B) The species has 16 sets of chromosomes per cell.
C) Each cell has eight homologous pairs.
D) During the S phase of the cell cycle there will be 32 separate chromosomes.
E) A gamete from this species has four chromosomes.
For a species with a chromosome number of 2n=16, each cell has eight pairs of homologous chromosomes. There are not 32 chromosomes, 16 sets, or four chromosomes in a gamete.
In biology, the chromosome number 2n=16 indicates that the organism is diploid and has 16 total chromosomes, which are organized into 8 homologous pairs. So, the correct answer is option C) Each cell has eight homologous pairs. The number 16 (2n) represents the total number of chromosomes, not how many sets there are, making option B incorrect. One should not interpret this to mean there are 32 chromosomes in total, so option A is also incorrect. During S phase of the cell cycle DNA replication happens, but this doesn't change the number of chromosomes, just the number of DNA molecules, therefore, option D isn't right. Lastly, a gamete (sex cell) from this species would have n=8, or half the number of chromosomes, contradicting option E.

Answer:
Cell Membrane
Explanation:
The cell membrane decides what comes in and goes out of the cell. If removed waste, liquids or germs could get in and disrupt the cell's homeostasis
Answer:
The correct answer would be nonsence mutation.
It is a type of point mutation in which an amino acid coding codon is converted into a stop codon.
It results in the termination of a premature polypeptide chain.
For example, the mutation of codon third GCT into ACT in which guanine is replaced with adenine.
DNA template strand 3' - TAC TGA GCT GTG GCT CGC TCG ACT - 5'
mRNA sequence 5' - AUG ACU CGA CAC CGA GCG AGC UGA- 3'
Amino acid sequence Met Thr Arg His Arg Ala Ser Stop
Mutated DNA template strand 3'-TAC TGA ACT GTG GCT CGC TCG ACT -5'
mRNA sequence 5'- AUG ACU UGA CAC CGA GCG AGC UGA-3'
Amino acid sequence Met Thr Stop
The type of mutation that always creates a stop codon is a nonsense mutation.
Nonsense mutations are point mutations that result in the conversion of a codon that encodes an amino acid into a premature stop codon. A stop codon is a specific sequence of three nucleotides (either UAA, UAG, or UGA) that signals the termination of protein synthesis during translation.
When a nonsense mutation occurs, it leads to the premature termination of the protein synthesis process, as the ribosome encounters the stop codon and stops the translation prematurely. As a result, the protein synthesized from the mutated gene is truncated and typically nonfunctional.
Nonsense mutations can arise from various genetic alterations, such as single nucleotide substitutions, insertions, or deletions. The resulting premature stop codon can lead to the production of a truncated protein or the degradation of the mRNA molecule through a process called nonsense-mediated mRNA decay (NMD).

If a white horse and a black horse are bred together, what percentage of the offspring will be roan and express both colors in their hair?1 point)

The dominant traits are those that are expressed phenotypically, whereas recessive traits are masked by the dominant traits.
The dimples are the traits, which are expressed phenotypically.
Let the alleles for the heterozygous parent with dimples be Dd. The other parent not having dimples will have the genotype dd.
The combination between the Dd and dd will result in:
Dd, Dd - heterozygous combination of alleles
dd, dd - purebred for the alleles
Similarly, the genotype of the hair color of the horse is white and black .
The cross between the parental genotype will result in 100% heterozygous offspring with genotype
The result will be due to codominance, in which both the characters of the parent will be expressed in the offspring such that the horse will have black and white colors.
Therefore, the answers will be 50% and 100%.
