Answer:
you can't see sickle cell in a karyotype a it is inside one of the chromosomes
it is a single gene disorder
Explanation:
The answer is no, high biological fitness in one environment doesn’t have to be high in another environment.
Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. Fitness depends on environment so it changes if the environment changes. The fitness of a genotype is manifested through its phenotype, which is affected by the environment.
Answer;
-Carbon-14 decays into nitrogen-14.
-Once a living thing dies, it no longer takes in carbon.
-Carbon-14 dating works for fossils as old as 50,000 years.
Explanation;
-Geologists do not use carbon-based radiometric dating to determine the age of rocks. Carbon dating only works for objects that are younger than about 50,000 years, and most rocks of interest are older than that.
-Carbon dating is used by archaeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years.
-Carbon-14 has a half life of 5730 years, meaning that 5730 years after an organism dies, half of its carbon-14 atoms have decayed to nitrogen atoms.
