A peptide bond links amino acids in proteins.

In n-type semiconductors, the majority charge carriers are electrons.

Tendons are connective tissues that connect muscles to bones, allowing for movement.

Adipose tissue is a type of connective tissue that stores fat and provides insulation and cushioning.

Diamond crystallizes in a cubic crystal system, specifically in a face-centered cubic lattice.

Beta plus decay involves the conversion of a proton into a neutron, emitting a positron.

Ciliated columnar epithelium is found in the lining of the respiratory tract, where it helps to trap and move particles out of the airways.

Simple columnar epithelium is specialized for absorption and secretion, commonly found in the intestines.

Competition occurs when two species vie for the same limited resources, which can negatively impact both species.

Liquid water exhibits hydrogen bonding due to the attraction between the hydrogen atoms of one water molecule and the oxygen atom of another.

Structural isomerism occurs when compounds have the same molecular formula but different structural arrangements.

The complex [Co(en)2Cl2]+ can exhibit optical isomerism due to the presence of bidentate ligands (en = ethylenediamine) which can create non-superimposable mirror images.

The complex [Cr(en)3]3+ shows optical isomerism because it contains bidentate ligands (en = ethylenediamine) that can create non-superimposable mirror images.

Ball-and-socket joints, such as the shoulder and hip joints, allow for the greatest range of motion.

The elbow is a hinge joint, allowing movement in one plane, primarily flexion and extension.

The shoulder joint is a ball and socket joint, allowing for a wide range of motion.

The shoulder and hip joints are ball and socket joints, allowing for a wide range of motion.

The knee joint is classified as a hinge joint, allowing movement primarily in one plane.

In opposite leaf arrangement, two leaves grow at each node directly across from each other.

A convex lens is used to correct hyperopia (farsightedness) as it converges light rays before they enter the eye.

The hip joint allows for flexion, extension, abduction, adduction, and rotation, making it a versatile joint.

Isometric contraction occurs when the muscle length remains the same while tension is generated.

Smooth muscle is involuntary and found in the walls of internal organs, facilitating functions like digestion.

Cardiac muscle is responsible for the involuntary contractions of the heart, leading to the heartbeat.

Skeletal muscle is striated and under voluntary control, allowing for conscious movement.

The body-centered cubic (BCC) structure features body-centered packing, where one atom is at the center of the cube and eight atoms are at the corners.

AIDS is caused by the Human Immunodeficiency Virus (HIV), which is a virus.

Cholera is caused by the bacterium Vibrio cholerae.

Liverworts are characterized by having a thallus, which is a flat, leaf-like structure.

Angiosperms are characterized by having seeds enclosed within a fruit, which is a key feature of this group.
