Answer:
D) the presence or absence of a Nucleus
Explanation:
A Nucleus is present in a Eukaryotic cell. A Nucleotide is present in a Procaryotic cell. If there is a nucleus present, it is a Eukaryotic cell
D.) southwest has the warmest climate
There Is a phase in mitosis called G0, which occurs before the other stages. jn this stage, cells grow in order to become big enough go divide, meaning cells take the time to grow in order to divide at the same sizs.
Answer: The water cycle is the path that all water follows as it moves around Earth in different states. Liquid water is found in oceans, rivers, lakes—and even underground. Solid ice is found in glaciers, snow, and at the North and South Poles. Water vapor—a gas—is found in Earth’s atmosphere

The given question is incomplete, the complete question is:
Steroids are cholesterol based hormones. Nerve Growth Factor (NGF) is a water-soluble signaling molecule. Both have essential roles in cell function and organismal development. How are they received by the cell? A) Receptors for steroids are located in the plasma membrane and receptors for NGF are located in the cytosol. B) Receptors for steroids and NGF are located in the plasma membrane, C) Receptors for steroids and NGF are located in the cytosol, D) Receptors for steroids are located in the cytosol and receptors for NGF are located in the plasma membrane
Answer:
The correct answer is option D, that is, for steroids the receptors are situated in the cytosol and for NGF the receptors are situated in the plasma membrane.
Explanation:
NGF or the nerve growth factor is the water-soluble signaling molecule, and steroids are the cholesterol-based hormones. Both possess important functions in cell activities and the development of organisms. They are attained by the cells with the help of receptors for steroids situated in the cytosol, and the NGF receptors situated in the plasma membrane.
The plasma membrane permits the hydrophobic molecules, that is, water-insoluble molecules to pass through it. The water-insoluble molecules are the steroids, therefore, it can easily go through the plasma membrane and thus possess receptors within the cytosol. On the other hand, the water-soluble or the hydrophilic molecules are the NGF, they fail to pass through the plasma membrane, and thus, possess receptors on the plasma membrane.
