Sickle cell anemia is a condition that deals with the genetic disorders in which valine replaces glutamate at 6th position. it is transmitted through father. all the options are correct except its passing from both parents.
What happens in sickle cell anemia ?It is a genetic disorder in which normal RBC structures gets distorted and it gets the shape of sickle thus called sickle cell anemia. The distorted RBC are unable to carry oxygen in themselves.
It is found on the X chromosomes and the male is a carrier if the XY genotype of the male carries the X chromosome that is malfunctioned then it leads to the condition in the offspring.
Thus, sickle cell anemia can be treated as well via the blood transfusions.

Proteins to be secreted outside the cell are formed at ribosomes on the surface of the ______ endoplasmic reticulum.
Answer:
Proteins to be secreted outside the cell are formed at ribosomes on the surface of the rough endoplasmic reticulum.
Proteins to be secreted outside the cell are formed at ribosomes on the surface of the rough endoplasmic reticulum.
How protein is synthesized?Ribosomes, which are tiny, elongated organelles with a round shape, are found on the rough endoplasmic reticulum and are responsible for producing those proteins.
After prolonged chase times, secretory vesicles carrying the radiolabeled proteins from the Golgi apparatus to the cell surface merged with the plasma membrane to discharge their contents outside of the cell.
While the smooth endoplasmic reticulum does not contain ribosomes and produces lipids and helps the cell detoxify, the rough endoplasmic reticulum produces protein and contains ribosomes.
Therefore, the rough endoplasmic reticulum is responsible to synthesize proteins to be secreted outside the cell.

The study of a living being is called biology. There are two types of species that are living and these rare plants and animals.
The correct answer is described as follows
What is taxonomy?The classification of the species and arranging them into different hierarchy levels is called taxonomy.The criteria for the classification is changed over periods of time and still changing as we are developing in modern science.
The first classification has used the habitat to classify the species. After that various scientists came they start to classify the species in a different manner.
The other classification is based on the cell wall and cell organization.
After that, the final classification is based on the 5 different criteria out of which the criteria are:-
