b
Explanation:
i had this same quiz when i was younger
I believe a peccary is a placental because its fetuses are fed via placenta.
The thymus becomes smaller with age as well as decreased immune system function.
The process of shrinking of the thymus is known as involution. This process occurs with any tissue that is not in frequent use. Before an individual reaches adulthood, the immune system has produced most of its T-cells. Therefore, new T-cells do not need to be produced, so the tissue of the thymus gland is replaced by adipose tissue.
The <span>energy of the photon emitted when the electron in a hydrogen atom drops from energy level E5 to energy level E2 is 2.85eV
Now, the energy of the ground state is -13.6 eV.
</span>the energy of the first state (n = 1) is -3.39 eV.
the energy of the fifth state is -0.54 eV.
Now, When an electron drops from higher to lower state, then energy difference is same as the energy of the photon emitted, is
= E5 - E2
= -0.54 eV -(-3.39 eV)
= 2.85 eV
It conveys emotions or moods.
