Answer:
type A
Explanation:
If a person receives an O allele from one parent and an A allele from another parent then this person will have A type blood.
Blood group of a person is decided by the presence or absence of antigen A and B & their antibodies. We have ABO type of blood group system in which A and B antigens are co-dominant i.e. if both the antigens are present on the surface of red blood cells then the person will have AB blood group because both are equally dominant.
Rest of the blood groups and their allelic combinations are mentioned as under:
A blood group → AA or AO
B blood group → BB or BO
AB blood group → AB
O blood group → OO
In the given question the person has one O allele but it is receiving an A allele also. A allele is dominant on O allele so the person will have A type blood group.
O type blood group will be exhibited by a person only when it has both the alleles as 'O'.
Large scale electrical energy production largely depends on the use of turbines. Nearly all of the world's power that is supplied to a major grid is produced by turbines. From steam turbines used at coal-burning electricity plants to liquid water turbines used at hydro-electric plants, turbines are versatile and can be used in a number of applications. There are also gas turbines that com bust natural gas or diesel fuel for them to refuse. remote locations or where a large backup power supply is required.
Spontaneous generation is a concept of the origin of life that can be traced back to the theories of Greek philosophers Aristotle and Plato and persisted through the Enlightenment Period. While some Enlightenment Period scientists experimented to show that life could arise even under controlled conditions, their methods were not sanitary and microbial contamination of the containers used gave dubious results. it was Louis Pasteur who is generally credited with refuting the idea due to his more advanced and precise control of starting conditions that revealed that no life arose from non-life. This strongly established that life cannot arise from non-life.
Today, we have similar superstition by some naturalists who posit that natural processes are capable of producing living entities, whether it is SETI searching for extraterrestrials, NASA astrobiologists searching for aliens and panspermia, or other life enthusiasts similarly inclined.
Currently, the term abiogenesis is used by naturalists to detail the emergence of life from non-life,and has failed miserably to do so. It is very similar to the spontaneous generation idea that was disproven and lost favor in the 1800's. The current understanding strongly favors abiogenesis because it ideologically fits the belief system that all reality is the result of natural processes and forces, but there is not evidence of its validity, not even at the simplest biochemical levels.
Answer: Questions bordering on Public health.
Explanation:
1. What measures are currently being put in place to isolate the animal to human reservoir vector for the Ebola Virus?
2. How to measure relative mRNA level of a particular gene from a gene expression data sequence of diseased versus control.
3. What plans have been put in place to develop a vaccine for Corona virus
4. What if the CDC,WHO are all mistaken in their assessment of the effects of air pollution in man?
1. football players or rugby players
2. basketball player or martial artists
3.rowers or triatheletes
a. muscular strength
b. endurance training
c. endurance and strength training
Answer:
football players or rugby players : endurance and strength training
basketball player or martial artists : muscular strength
rowers or triatheletes : endurance training
Explanation:
1. Football players or rugby players require to be physically active(stamina) and aerobically fit. This is because they have to play in the ground to cover long distances focusing on an object. This gives them tolerance and strength.
2. Muscle strength is important in basketball and martial arts because while gaining strength, speed, and endurance, you are also strengthening tendons and ligaments which will reduce the chances of injuries, such as sprains and tears.
3. Rowers or triathletes both are alternatives of racing that increase endurance training. Patience is key to cover a long distances on racing or running.
