Answer:
combines genes from organisms of different species in a lab
Explanation:
Recombinant DNA technology involves the process of joining the genes (DNA) of different multiple species in order to insert into another organism (host). Recombinant DNA technology has many applications in genetic engineering.
One example of Recombinant DNA is the synthesis of Insulin in bacteria cell where a human insulin gene is first inserted into a plasmid vector, then inserted into a bacterial cell that uses its expression abilities to transcribe and translate the gene into INSULIN protein.
This procedure is usually conducted in a laboratory with the use of certain laboratory equipments.
The right option is d) bubbles
The production of bubbles when baking soda mixes with an acid such as vinegar is the observation that indicated a chemical property of the baking soda.
Baking soda (also known as sodium bicarbonate) is a nonflammable, white crystalline powder. Baking soda is odorless, and alkaline. Baking soda reacts with vinegar (acetic acid) to produce carbon dioxide (a gas), water, sodium ion and acetate ion. Baking soda is used for many purposes such as; as an antacid for treating indigestion, for baking, in fire extinguishers, as a water softener, as a pesticide, and to remove dirts from materials.
Sperm cell. Meiosis is the creation of Sex cells, therefore, the answer would be Sperm Cell.
Answer:
Endocardium
Explanation:
The endocardium makes the innermost lining of the wall of the heart. It is present over the thin layer of connective tissue. The function of the endocardium is to provide a smooth lining for the chambers of the heart. The valves present in the heart also have endocardium. The dense connective tissue of the heart valves is covered by endocardium.
The presence of the smooth endocardium made up of endothelium reduces the surface friction as blood passes through the heart. The endocardium of heart chambers is continuous with the endothelial lining of the large blood vessels that are attached to the heart.
