Biology Chapters 1-7

The femur, also known as the thigh bone, is the longest and strongest bone in the human body, extending from the hip to the knee. The tibia and fibula are bones in the lower leg, while the humerus is in the upper arm.

Agent dispersal refers to the process of seeds being spread by external agents such as wind, animals, or water.

Xylem is the vascular tissue in plants that transports water and dissolved minerals from the roots to the leaves, while phloem is responsible for transporting sugars and other organic compounds. Stomata are small openings on the surface of leaves that allow for gas exchange, and guard cells regulate the opening and closing of stomata.

The humerus is the bone located in the upper arm, while the femur is located in the thigh, the tibia is located in the lower leg, and the radius is located in the forearm.

A peach is classified as a drupe because it has a single seed enclosed in a hard shell surrounded by fleshy tissue which is characteristic of drupes.

The tibia and fibula are the two bones that make up the lower leg. The tibia is the larger and stronger of the two, supporting most of the body's weight. The fibula is a thinner bone located next to the tibia.

Osmosis specifically refers to the one-way diffusion of water through a semi-permeable membrane, while the other terms do not accurately describe this process.

Ellipsoid joints are considered the most freely movable joints in the body due to their unique structure and range of motion capabilities.

The axial skeleton includes the skull, vertebral column, and rib cage, while the appendicular skeleton includes the bones of the upper and lower limbs as well as the shoulder and pelvic girdles.

The cotyledon is the part of the plant embryo that develops into stems and leaves, while the root, radicle, and hypocotyl are responsible for other functions in plant development.

The deltoid muscle is located in the shoulder and is responsible for arm abduction.

The correct scientific term for 'abs' is 'abdominus', the other options provided are not the correct scientific terms for this muscle group.

Leaves can be classified as compound, simple, palmate, or needle based on their structure and arrangement of leaflets.

Leaves can be classified as either simple or compound based on their structure. Simple leaves have a single leaf blade, while compound leaves are divided into multiple leaflets. Serrated refers to the edge of the leaf being toothed, and palmate describes leaves with lobes radiating from a central point.

Fibrous roots are thin, branching roots that spread out close to the surface, while tap roots are thick main roots that grow straight down. Adventitious roots arise from stems or leaves rather than from other roots. Storage roots are swollen roots that store nutrients for the plant.

A tap root system consists of a main root known as the tap root, which grows vertically downward with little or no lateral branching. Fibrous roots are shallow and highly branched, while adventitious roots grow from stems or leaves. Aerial roots are roots that grow above the ground.

Deciduous trees shed their leaves in the fall, while evergreen trees maintain their leaves year-round. Coniferous trees are usually evergreen, and palm trees do not lose their leaves in the same way as deciduous trees.

Coniferous plants are known for their cone-bearing reproductive structures, which contain seeds. Deciduous plants shed their leaves annually, evergreen plants have foliage that remains green throughout the year, and perennial plants live for more than two years.

Mosses and liverworts belong to the group of non-vascular plants known as bryophytes. They are distinct from angiosperms (flowering plants), algae, and ferns.

Algae are primitive chlorophyll-containing plants that can be found in various aquatic environments.

A scavenger is an organism that feeds on dead or decaying organic matter, while a parasite feeds on a living host, a predator hunts and kills other organisms for food, and a producer creates its own food through photosynthesis or chemosynthesis.

Kelp, gulfweeds, and rockweeds are commonly known as brown algae due to their color and characteristics. Red algae, green algae, and blue algae are different types of algae with distinct features and characteristics.

Epithelial tissue is responsible for protecting the body from the external environment and plays a key role in absorption, secretion, and sensory perception.
