Answer:
Option (1), (2) and (3).
Explanation:
Doppler effect may be defined as the change in wavelength due to the the movement of sound or radiowaves travels from the object. The frequency remains same if the distance between the receiver and sender's electromagnetic wave distance is same.
Doppler effect helps to learn about the universe behavior. Hubble used the Doppler effect to study the velocity of galaxy. The galaxy motion can be indicated by the wavelength and light.
Thus, the correct answer is option (1), (2) and (3).
Sickle cell trait is not a disease; it is an inherited red blood cell condition that can affect athletes at all levels. While sickle cell trait is not a barrier to playing competitive sports, athletes with sickle cell trait have experienced significant physical distress, including collapse and death during intense exercise. Heat, dehydration, inadequate acclimatization, altitude and asthma can increase the risk for medical complications in athletes with sickle cell trait Through awareness, education and proper physical conditioning under the supervision of a primary athletics health care provider, athletes with sickle cell trait may safely achieve outstanding athletic performance
Answer:
I would expect to see a greater variety of traits observed. Simplistically, I would expect to see people with blue eyes and brown hair, blonde hair or red hair. Whereas in a population where chromosomes do not cross over, I would expect to see traits that are more frequently associated with each other. For example, I would expect to see a greater proportion of blue eyed people to be blonde because the gene for hair colour is more frequently associated with the gene for eye colour.
Explanation:
<span>Mitosis is carried out for growth and development processes. The cell divide and multiply for growing and removing the worn out cells/damaged cells. Two identical daughter cells are formed in mitosis. Errors in the same may cause genetic disorders, Sex cells divide by the process of meiosis. </span>
