This is because
1.they are in the right habitat for those kinds of plants
2.the gardener is taking care of them like watering them and not watering when they are about to die or rarely watering them, and always giving them the right amount of water
3.the placement of the plants helps to, they are given the perfect amount of sun and nutrients from the ground
Question: One way that researchers study the effects of trans fats on people's health is by setting up controlled experiments. For example, in an experimental feeding trial, participants agree to stick to specific diets that the researchers prescribe. In this case, the researchers might vary the proportions of saturated, unsaturated, and trans fats in the diet of each participant. Throughout the study, the health status of the participants is monitored closely.
Suppose that you are a researcher designing an experimental feeding trial. How would you set up your study and what limitations would you face?
Drag the labels onto the flow chart to identify the elements and limitations of your experimental design.
Explanation:
Hypothesis: Trans fat have found having negative effect on the cardiovascular effect.
Prediction : Eating more trans fats will have more risk of cardiovascular health problems.
Experiment: Feeding some people with a diet of higher trans fat and feeding others with a diet lower in trans fat.
Data collection: Blood samples are taken to measure the fat and cholesterol level in the two groups.
Practical limitations:* Is it possible to completely regulate people's diet?
* Are other life style factors affecting cardiovascular
health?
Ethical Limitation: Are we putting individuals health at risk?
Answer:
Allele IA produces antigen A
Allele IB produces antigen B
Allele i produces No antigen
To predict the genotype the main thing is that I is dominant to i allele.
So, the ABO grouping genotype should be like this.
Genotypes Phenotypes
IA IA A
IA i A
IB IB B
IB i B
IA IB AB
i i O
This the main ABO blood grouping genotyping and phenotyping used in transfusion medicine. And this is the most abundant test performed in the blood banks for transfusion of blood and record management.
Explanation:
Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
