Pseudopods are the feet-like structures of amoebas. Pseudopods are temporary projections of the cell membrane and cytoplasm that extend and retract to facilitate movement and capture food. They are called "false feet" because they are not true appendages but rather dynamic extensions of the cell.

Amoebas use pseudopods for locomotion by extending them in the direction of movement and then pulling the rest of the cell along. These structures allow the amoeba to change shape and move in a fluid and flexible manner.

Pseudopods also play a role in capturing prey. When an amoeba encounters a food particle, it extends pseudopods around it to engulf and incorporate it into its cell body through a process called phagocytosis. Overall, pseudopods are essential for the amoeba's ability to move, feed, and interact with its environment.

The muscle named for the direction of its fibers is External Oblique. Option C is correct.

The external oblique muscle is a paired muscle located on the sides and front of the abdomen. It is named "external" because its muscle fibers run obliquely or diagonally from the lower ribs to the pelvis.

The external oblique muscle originates from the lower eight ribs and inserts into the linea alba (a fibrous structure in the midline of the abdomen) and the iliac crest (the curved ridge on the top part of the hip bone). The muscle fibers run in a downward and forward direction, diagonally across the abdomen.

The external oblique muscle plays a crucial role in the movement and stability of the trunk. It is responsible for flexing and rotating the trunk, as well as compressing the abdominal contents. When both sides of the external oblique muscle contract together, it aids in flexing the spine forward. When only one side contracts, it assists in lateral flexion (side-bending) and rotation of the spine.

To promote off-season flowering in long-day plants, techniques such as artificial lighting, temperature manipulation, and hormonal treatments can be used.

Long-day plants require a specific amount of daylight to initiate the flowering process. To promote off-season flowering in these plants, artificial lighting can be utilized. By supplementing natural daylight with artificial light sources, the plants can receive extended periods of light, mimicking longer days and stimulating flower formation.

Temperature manipulation is another approach to promote off-season flowering. By carefully controlling the temperature conditions, either by providing warmer temperatures or simulating temperature fluctuations, it is possible to trigger flowering in long-day plants outside their typical flowering season. This technique can be achieved through the use of temperature-controlled environments, such as greenhouses growers  or growth chambers.

Hormonal treatments can also be employed to promote off-season flowering. Plant hormones like gibberellins and auxins can be applied to the plants to induce flowering. These hormones act as signals that override the plant's natural responses to day length, allowing it to bloom even in non-optimal conditions.

By employing these techniques, long-day plants can be encouraged to flower during off-season periods, providing opportunities for commercial production, research, or simply enjoying blooms outside their regular flowering time.

In photosynthesis, the carbon in [tex]CO_{2}[/tex] is initially fixed to the molecule RuBP (ribulose-1,5-bisphosphate).

The process of carbon fixation is a crucial step in photosynthesis, where carbon dioxide ([tex]CO_{2}[/tex]) is converted into organic molecules. This process occurs in the stroma of the chloroplasts in plant cells. The primary molecule involved in carbon fixation is RuBP, which stands for ribulose-1,5-bisphosphate.

RuBP serves as the acceptor molecule  [tex]CO_{2}[/tex] during the initial stages of carbon fixation. The enzyme responsible for this reaction is called rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase). Rubisco catalyzes the reaction between [tex]CO_{2}[/tex] and RuBP, resulting in the formation of an unstable intermediate compound. This compound then breaks down into two molecules of 3-phosphoglycerate (3-PGA).

3-PGA is subsequently converted into glyceraldehyde 3-phosphate (G3P), which is a key intermediate in the synthesis of glucose and other carbohydrates. G3P can be further utilized in various metabolic pathways to produce sugars, starches, and other organic compounds necessary for plant growth and energy storage.

While NADPH and ATP play critical roles in the overall process of photosynthesis, they are not directly involved in the initial carbon fixation step. They are generated during light-dependent reactions and are used in subsequent steps of photosynthesis, such as the reduction of 3-PGA to G3P.

The correct answer is b. double bonds. Lipids' quantity of double bonds affects how saturated or unsaturated they are (option b). Lipids can be classified as saturated (no double bonds) or unsaturated (one or more double bonds) based on the number of double bonds present in their fatty acid chains.

The number of double bonds present in the fatty acid chains of different lipids determines the degree of saturation or unsaturation. LONG hydrocarbon chains with a carboxyl group at one end make up fatty acids, which are the fundamental components of lipids. When there are no double bonds between the carbon atoms in a fatty acid's hydrocarbon chain, the fatty acid is said to be saturated. Saturated fatty acids are solid at normal temperature due to their straight structure and propensity to pack closely together.

The hydrocarbon chain of unsaturated fatty acids, on the other hand, contains one or more double bonds. In the fatty acid structure, double bonds cause kinks that inhibit tight packing. It's common to refer to unsaturated fatty acids as oils because they are often liquid at room temperature. Lipids can be more or less saturated or unsaturated, which affects their physical characteristics and ability to operate in biological systems.
