Answer:
Patient-oriented: performed on humans with direct contact between the patient and the investigator.
Disease-oriented: identify molecules and cells linked to a disease.
Explanation:
Clinical research is a study conducted on humans, design to develop techniques and create knowledge. It involves several activities orientated to test a hypothesis and draw conclusions about diseases.
Patient-oriented clinical research is a specific type of clinical study with humans, that requires an <u>interaction between the patient and the investigato</u>r. This research is performed to detect, treat and prevent human diseases as well as understand the disease's mechanism to develop technologies and create knowledge in this field. For example creating a less invasive technique to treat a patient, heart assist devices, vaccines, inhaled medicine for pulmonary problems and cellular therapies.
Disease-oriented clinical research is a study that seeks to understand <u>molecular or cellular features that are linked to human diseases</u> to identify their response to treatment. For example identify cancer target molecules, use of genes and proteins for the diagnosis and treatment of cardiovascular diseases, stem cells to treat autoimmune diseases and genetic therapies to treat molecular and cellular problems.
The Himalayan Rabbit sports black fur on its extremities. This is due to an ancestral trait; the Himalayan Rabbits carry “temperature sensitive tyrosinase genes” which controls fur pigmentation. The rabbit’s ancestors, which would have had to survive in the cold Himalayan environment would have, through natural selection, favored a gene that allows for a darker pigmentation. Through evolution the Himalayan Rabbit passed down the genotype for a melanin producing gene, which activates in low temperatures, changing the individual rabbit’s phenotype to fit the climate.
So your answer is choice 1
Hope this helped!

Answer:
Rr x rr
Explanation:
Let's say
RR is a tall plant.
Rr is tall
& rr is a small plant
The only genotypes you can get to make two tall and two short is if you use a hetero pair and a same ressesive (rr) genes.
