Lustre is basically due to free electrons. As we move down the group, the size of the atoms increases and more shells are added, so due to screening effect, effective nuclear charge is less and hence electrons are loosely bound. Moreover, the non-metallic property decreases on going from top to bottom of the group. Therefore, iodine is lustrous.

The charge of the electron is equivalent to the magnitude of the elementary charge (e) but bearing a negative sign. Since the value of the elementary charge is roughly 1.602 x 10-19 coulombs (C), then the charge of the electron is -1.602 x 10-19 C.

Kidneys are bean-shaped and located at the back of abdomen, one on either side of backbone.
Its inner concave surface has a depression called hilum through which renal artery enters and renal vein leaves the kidney. Kidney has two regions: outer cortex and inner medulla. Each kidney has a large number of filtering units called nephrons .

The excretory system of human body consist of two kidneys,two ureters one urinary bladder and urethra.Each kidney posses millions of nephrons,which is a thin,long-twisted tubular structure.The tubule of each nephron begins as a cup-shaped capsule made of two membranes called as Bowman’s Capsule.
Bowman’s Capsule encloses a globular tuft of cappillaries in the hollow of the cup called as Glomerulus.

Amoeba obtain its food from outer surrounding with the help of pseudopodia by a process called phagocytosis. If the food material is solid then, phagocytosis term is used. But if the food is liquid or fluid then a similar process is there, called pinocytosis. Both the processes togather known as endocytosis (engulfing something). Lterally, phagocytosis means, 'cell eating', that is., cell is eating and pinocytosis means, 'cell drinking', that is., cell is drinking.

The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus . The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.
Cerebrum: The cerebrum is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes": the frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
- Frontal Lobe- associated with reasoning, planning, parts of speech, movement, emotions, and problem solving
- Parietal Lobe- associated with movement, orientation, recognition, perception of stimuli
- Occipital Lobe- associated with visual processing
- Temporal Lobe- associated with perception and recognition of auditory stimuli, memory, and speech
Thalamus-It is a large mass of gray matter deeply situated in the forebrain at the topmost portion of the diencephalon. The structure has sensory and motor functions. Almost all sensory information enters this structure where neurons send that information to the overlying cortex.
Hypothalamus-It is a part of the diencephalon, ventral to the thalamus. The structure is involved in functions including homeostasis, emotion, thirst, hunger, circadian rhythms, and control of the autonomic nervous system. It also controls the pituitary.
Midbrain-It is involved in functions such as vision, hearing, eyemovement, and body movement.
Cerebellum - The cerebellum has two hemispheres and has a highly folded surface or cortex. This structure is associated with regulation and coordination of movement, posture, and balance.
Pons- It is involved in motor control and sensory analysis. It has parts that are important for the level of consciousness and for sleep.
Medulla Oblongata- This structure is present between the pons and spinal cord. It is responsible for maintaining vital body functions, such as breathing and heartrate.

Systole is the contraction of heart chambers, driving blood out of the chambers. Systole is initiated by the sinoatrial node, which is the heart's natural pacemaker. These cells are activated spontaneously by depolarization of their membranes. During systole, blood is driven through the aorta and pulmonary artery after each dilation or diastole.
Diastole is the period of time when the heart relaxes after systole.
