Emir is most probably taking a class on human anatomy. Human anatomy involves all the structures in the composition of the human body. Human anatomy can be studied either by systems (i.e. cardiovascular system, respiratory system, etc.) or by regions (i.e. thoracic anatomy, abdominal anatomy, pelvic anatomy, head and neck anatomy, etc.) depending on the course.
It is related to thyroid dysfunction because one main cause of exophthalmos is the thyroid eye disease. It is a condition were the tissues inside the eyeballs would swell due to too much thyroid activity. Exophthalmos is known as proptosis and is a term used for bulging eyeballs. This condition is an autoimmune type and one in every three people would have this condition. It is common for women in their 30s to 50s and for people who smoke. Other causes of this condition are bleeding at the back of the eyes, abnormal shape of the blood vessels and infection of the tissues in the eyes.<span />
Ribosomes<span> consist of two </span>major components<span>: the small </span>ribosomal<span> subunits, which reads the rna , and the large subunits, which joins amino acids to form a polypeptide chain. Each subunit is composed of one or more </span>ribosomal<span> rna ( molecules and a variety of </span>ribosomal<span> proteins .HOPE THis helps! :)

Answer: A or C
B would not make sense, and no cell can mock a mitochondria
It would most likely be A
Answer:
Sex Linkage
Explanation:
Sex linkage is the phenomenon in which the expression of genes depends on the gender of the organisms because genes for specific traits are located on the sex chromosomes of organisms.
What are sex chromosomes:
They are usually a pair of chromosomes present in higher organisms like humans and other mammals that combine during fertilization of male and female gametes and determine the sex of offspring. In humans they are X and Y chromosomes and when there is an XX offspring, she will e female and when there will be Xy offspring , he will be male.
Significance:
-
Now there are some genes that are present only on sex chromosomes of the organisms like genes for beard are present in human Y chromosome of men, However,genes found on the X chromosome can be found in either males or females.
- Sex linked genetic disorders are very common in human males because males receive only one copy of X chromosome while females receive two copies. So only one copy of defective gene is enough for the expression of disease in males while in women two copies are needed if the trait is recessive.
- For example: There is a disease called hemophilia in which the blood is unable to clot even after minor injuries and can be life threatening.
- Hemophilia is an X linked recessive disorder and is an example of sex linked traits controlled by sex linked genes.
Hope it helps!
