Answer: Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.
Explanation:
Answer;
The two processes used by producers to obtain energy are photosynthesis and chemosynthesis.
Explanation;
Producers are those organisms that can make their own energy in an ecosystem using biochemical processes. These biochemical processes are photosynthesis and chemosynthesis.
Photosynthesis involves use of energy from the sunlight together with water and oxygen to make simple sugars. The process converts solar energy to chemical energy (simple sugars).
Chemosynthesis involves use of chemicals as the energy source, rather than sunlight , to make simple sugars such as glucose.
Glucose from both processes is then used for respiration to generate energy or stored in form of starch.
Answer:
B.The plant will grow to full maturity and produce flowers instead.
The medical term nasopharyngitis is used specifically to refer to the swelling of the nasal passages (the nose) and the back of the throat.
<h3>What is nasopharyngitis?</h3>
It is associated with the rhinopharynx or nasopharynx, which is the sector of the pharynx that is next to the nostrils and above the back of the throat.
It is an inflammatory condition or a disease that is caused by the action of a virus in the upper respiratory system.
Therefore, we can conclude that the medical term nasopharyngitis is used specifically to refer to the swelling of the nasal passages (the nose) and the back of the throat.

Answer:
d. All of the above exemplify the difference between a population and an individual.
Explanation:
A population is a group of individuals of the same species that live in a particular geographical area and are able to interbreed. A population is described with respect to several features such as death and birth rates, age structure, density, dispersion, change in the population size due to density-dependent and density-independent factors and the survivorship curve.
These features are not exhibited by a particular individual. Natural selection also works at populations. The evolutionary forces act upon populations to change their allele and genotype frequencies. Therefore, populations are the unit of evolution and change genetically over time, not the individuals. Population ecology studies the size of a populations and the trends and causes of changes in the populations over time.
