The offspring are all heterozygous, and the allele for purple flower is dominant
Answer:
Black
Explanation:
In the mouse a certain colorless pigment precursor exists.
- If the B allele is present: precursor is converted into black pigment.
- If the genotype is bb: albino
In addition:
- If the A allele is present: black pigment is converted to brown pigment
- If the genotype is aa: black pigment is not converted and mouse remains black
If the mouse has a genotype aaBB, the colorless pigment is converted to black (because there is at least one B allele) but the black pigment cannot be converted into brown (because there's no A allele), so the mouse will have black fur,
Death by hypoxia can be caused by airway obstruction(strangulation) or poison(cyanide, CO).
In the case, there is a toxicology report saying the victim is poisoned by cyanide. The organ damaged also diffuse and not concentrated. Cyanide works by inhibiting an enzyme in the mitochondria that use oxygen. Therefore, the cells can't oxygen for cellular respiration, cause the tissue die of hypoxia. The oxygen is there but it can't be used. The laboratory report that found high oxygen level in the blood also supports the cyanide poisoning.
Cell specialization is essential to an organism because cell specialization is what allows cells to provide the essential functions of life for an organism that have a wide variety of functions and purposes. Cell specialization leads to the diversity of cells in an organism such as the human body that build and allow essential organs and bodily functions to occur. Cell specialization is an essential building block that allows multi-celled and complex organisms to move and function.
