Answer:
b) natural variation w/in a species
Explanation:
All the answer you put are evidence of evolution also I have done this before.
Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
The outer boundary of cytoplasm is the answer
Answer:
Yes.
Explanation:
In the tropical Pacific, like the western coast of central and south America, the surface of the sea is cooler than normal and that results in reduced rainfall, drought and increased fires. This definitely brings about a negative effect on wildlife, as there is less water and food available.
However, in South East Asia, a higher than normal rainfall is commonly experienced, which is good for agriculture.
Haemoglobin takes oxygen and gives it to the cells thus hemoglobin is free to carry more oxygen.
