Answer: Women are carriers for the disease hemophilia because hemophilia is an X-linked disease. The recessive allele for the disease is found on the X chromosome.
The sons of carrier women get hemophilia because males have one X chromosome and one Y chromosome. The sons of a carrier woman may inherit the affected X chromosome from their mother, and a Y chromosome from their father. They have only one X chromosome and one it's affected, will result in hemophilia.
Explanation: Women are carriers because in most cases, only one of their two X chromosomes are affected. The two female X chromosome is rarely affected.
Daughters of carrier women will not get the disease because they need two affected X chromosomes to manifest the disease. So even if they inherit one affected X chromosome from their mother, the second X chromosome they will inherit from their father will be normal. Therefore, daughters of carrier women can only be carriers.
The place where an organism lives and that provides the things the organism needs is called its habitat.

Explanation:
Matthias Jacob Schleiden was a German botanist who, with Theodor Schwann, cofounded the cell theory. In 1838 Schleiden defined the cell as the basic unit of plant structure, and a year later Schwann defined the cell as the basic unit of animal structure.
Answer:
The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.
Explanation:
A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to stabilize many polypeptides.
