B. spiral.
C. barred spiral.
D. elliptical.
The correct answer is (a) irregular.
An irregular galaxy does not have any distinct or regular shape. They do not belong to any any regular class of the Hubble sequence. They are sometimes chaotic in appearance. Structurally these galaxies do not have spiral arm or nuclear bulge. Collectively these galaxy make up one fourth of all galaxies. They are small in size and one tenth the mass of Milky way galaxy.
Since it is recessive, it will be out ruled unless two recessive genes combine. If one is AA and the other is Aa There will be AA, AA, Aa, Aa. AA is dominant, therefore Aa can have the possibility of either trait. so there is 6 possibility.
A recessive trait is a trait that is expressed when an organism has two recessive alleles or forms of a gene. Traits are features of organisms that can be observed, this includes physical characteristics such as hair and eye colour, and also characteristics that may not be readily apparent, e.g. the shape of blood cells.
Thus, the correct option is "0".

Answer: Polar covalent bond
Explanation:
In ionic compounds, electrons are transferred between atoms of different elements to form ions. But this is not the only way that compounds can be formed. Atoms can also make chemical bonds by sharing electrons equally between each other. Such bonds are called covalent bonds
B. Cells need to get rid of waste products.
C.cells cannot live unless they divide often.
D. Cell division is how organisms grow
Cell division is how organisms grow.
Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body.
The cell division process known as meiosis is what produces egg and sperm cells. A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.
Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.
Therefore, Cell division is how organisms grow.
