Answer:A gene is a short section of a DNA

Explanation: A gene is the fundamental unit of inheritance or hereditary in living organisms. A gene is the DNA segment that codes the information needed to produce an RNA or a protein. Some DNA molecules have short segments that do not code for amino acid sequence of a polypeptide product. These non translational or non coding sequences are called intervening sequences or introns. DNAs also contain coding segments which are called genes.

Butoxors [25]

Answer:

Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.

Explanation:

The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.

The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.

Thus, the correct answer is option (d).

What role does transpiration play in the water cycle
Airida [17]

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.

Studies have revealed that about 10 percent of the moisture found in the atmosphere is released by plants through transpiration. The remaining 90 percent is mainly supplied by evaporation from oceans, seas, and other bodies of water (lakes, rivers, streams).

Transpiration and plant leaves

Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions, such as temperature, humidity, sunlight availability and intensity, precipitation, soil type and saturation, wind, land slope, and water use and diversion by people. During dry periods, transpiration can contribute to the loss of moisture in the upper soil zone, which can have an effect on vegetation and food-crop fields.
