e❤❤..ur answer is...epithelial CELLS...explaination...Oxygen and carbon dioxide MOVE across what we call the respiratory SURFACE, and that consists of an alveolar epithelial cell and a pulmonary capillary ENDOTHELIAL cell. Now, this respiratory surface is also referred to as the respiratory membrane.

son why mature red blood cells (erythrocytes) have no mitochondria, is that (most) RBC ORGANELLES (including the nucleus) are EXPELLED during maturation. RBCs need very little energy for what they do — shuttling oxygen from lungs (or gills, or trachea) to tissues, and shuttling (some) carbon dioxide[1][1] (and other waste products) from tissues to lungs — RBC energy (ATP) requirements are satisfied by glycolysis, and by fermentation of the RESULTING pyruvate.RBCs stem from bone marrow, and once mature have a limited “lifetime” (some 120 or so days), during which their “main FUNCTION” is to transport gases. By getting rid of (most) organelles, SPACE for more hemoglobin is freed up, which is what the inhaled oxygen binds to.

Reproduction. During sexual reproduction, two parents are involved. ... This process combines the genetic material from both parents. The resulting organism will be genetically unique. The zygote will divide by mitosis and GROW into the embryo.Binary fission ("division in HALF") is a kind of asexual reproduction. It is the most common form of reproduction in PROKARYOTES such as bacteria. It occurs in some single-celled Eukaryotes LIKE the Amoeba and the Paramoecium. ... At the same time, the cell membrane divides to form 2 daughter cells.

cial types of cells which conduct impulses from one place to another in our body are called neurons or nerve cells.Nerve cells have the ability to generate and conduct electrochemical impulses.Neurons are the largest cells in our body and may measure upto a few metres in length.Based on their function, there are 3 types of neurons:- MOTOR neurons, sensory neurons and ASSOCIATION neurons. The special cells which SUPPORT the neurons and help them in their functioning are called Neuroglia. Neurons and Neuroglia TOGETHER form nerves.HOPE IT HELPS PLS MARK AS BRAINLIEST.

e POLLEN Grains? Spring is a time of new growth and fresh beginnings. DAYS get longer, the sun gets warmer, and flowers bloom in a magnificent SHOW of color. And as a result of these lovely blossoms everywhere, many of us find ourselves in sneezing fits. In order for flowers to propagate every year, they must be pollinated. And pollination sends millions of tiny pollen grains through the air, many of which end up in our nose. But pollen does not exist simply to make us miserable. Pollen grains represent the male portion of the reproductive process in plants and trees. These tiny bodies are swirling in the air and on the legs of insects so that they can join the female PART of the plant to create a new seed. This important process is known as fertilization. As we will discover, pollen plays a crucial role in the plant world.
