Homeotic genes regulate the development of structures. Logically, then, the mutation of this gene must result in improper structure development, such as structures in abnormal places. The answer is C.
Answer:
Chick with in the egg depend for all its energy and food requirement on the egg yolk , therefore egg yolk is rich in fat, protein, and cholesterol.
Explanation:
Before the egg breaks and the chick comes out, few days nourishment for chicks is required. Hence, the egg yolk needs to be nutritious as new developing chick (with in the egg) rely for essential nutrients (required for growth) on the egg yolk. Chick require energy from yolk, hence it is rich in fat (energy). It also needs to grow and develop, therefore egg yolk has lot of protein (building blocks). Lipid and cell with in the yolk help in formation of cell and strengthening of bones and feathers
The answer is A.
If the bicipe muscle contracts it will bring the forearm up because the insertion of this muscle is in the forearm.
One of the functions of this muscle is flexing the elbow, which would result in the action i already mentioned.
It couldn't be B, because that would be the work of another muscle, the triceps.
When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
