Answer:
At the most basic level of biodiversity, climate change is able to decrease genetic diversity of populations due to directional selection and rapid migration, which could in turn affect ecosystem functioning and resilience (Botkin et al.

Answer:
Cystic fibrosis mutation is recessive to normal allele because only one functional or normal allele is enough to produce a functional protein. So, if mutation is present in one allele then also, a normal protein can be made from normal allele. The presence of normal protein prevents the expression of disease.
In addition, mutated allele only results in the loss of function of protein which can be compensated by the expression of normal allele. It does not add any toxic effect to the protein. Consequently, the disease is inherited in autosomal recessive fashion.
In contrast, Huntington mutation not only alters the structure of the functional protein but also adds toxicity to it. The altered protein is enable to interact with 100s of other proteins and inhibit or decrease their function. So, if only one allele is present then also, the mutated protein will be produced and it will result in the phenotype. Consequently, it is inherited as autosomal dominant fashion.
Answer:
Case Studies, Checklists, Interviews, Observation sometimes, and Surveys or Questionnaires are all tools used to collect data. It is important to decide the tools for data collection because research is carried out in different ways and for different.

Answer:
Columnar epithelial tissue.
Explanation:
The above scenario confirms that these are simple columnar epithelial tissue because columnar cells are tall, narrow and nucleus in the tall column like cells located at the basal end of the cells. Columnar epithelial tissue are responsible for absorption and secretion of molecules. These are present at some part of digestive tract, female reproductive tract, and respiratory system.
