The population is growing more rapidly then before
Answer:
YES. This information is enough to assume that neither of the blood groups dominates over the other one.
Explanation:
<u>Available data:</u>
- A man with blood group B ----> Genotype IBIB or IBi
- A woman with blood group AB ---> Genotype IAIB
- Their daughter has blood group AB --> Genotype IAIB
The fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.
- If blood type B was dominant over A or AB, then the daughter should have Blood type B.
- If blood type A was dominant over B or AB, then the daughter should have Blood type A.
- Blood type AB tells us that both types are being expressed, A and B.
The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.
This is enough information to assume that neither of the blood groups dominates over the other one.
Answer:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing
The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions
If it is a healthy environment then the atmosphere will be happy meaning no dirty streets etc
The right answer is D. renal regulation.
Among the many factors that modulate tension (vessels, heart strength, blood volume ...), the kidney plays a vital role because it makes an enzyme called renin that helps increase blood pressure and it regulates the outflow of sodium and water, which contribute to the elevation or diminution of blood pressure in the arteries.
