Answer:
A.
half of its genetic material from each parent.
Test One: All short fur
Phenotype ratio: 4:0
Test Two: three short fur and one long fur
Phenotype ratio: 3:1
Test Three: all long fur
Phenotype ratio: 4:0
Genotypes for fur length dominant
G: FF, and Ff (These are the genotypes for short fur, short fur is a dominant gene.
P: Short fur is dominant
Genotypes and phenotypes for fur length recessive
G: ff
P: Long fur is recessive
If you have a hamster with short fur, the possible genotypes the hamster could have is FF, and Ff
If you have a hamster with long fur, the possible genotype is ff.
Answer: D. All living cells come from other living cells.
Explanation:
A is incorrect because organisms like bacteria and amoebas are unicellular, or have 1 cell.
B is incorrect because cells are specialized: nerve cells and muscle cells do not share the same function.
C is incorrect because inanimate objects are not alive and do not have cells.
D is correct because cells reproduce by mitosis, creating copies of themselves.
Answer:
The correct option is the number 2. Cystic fibrosis
Explanation:
Cystic fibrosis is a hereditary disease that affects the glands that produce mucus, sweat and digestive juices, this genetic disorder makes the secretions more sticky and thick, they accumulate and produces blockage in the tubes, ducts and passages, in particular in the lungs and pancreas.
The mucus block the ducts that carry digestive enzymes from the pancreas to the small intestine. Without these digestive enzymes, the intestines are not able to completely absorb nutrients in the food. The result is often, little increase in weight and growth, intestinal obstruction, particularly in newborns (ìleo meconium), among others.
Cystic fibrosis also affects the epithelial cells of the sweat glands, children suffering from this disorder may have a kind of salt layer on the skin. They can also lose abnormally high amounts of salt when they sweat on hot days.
