ation The working together of various ORGANS of the body of an organism in a proper manner to PRODUCE APPROPRIATE REACTION to a stimulus is called coordination.

e here your answer____The mitochondrion (plural mitochondria) is a double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them (for EXAMPLE, mature mammalianred blood cells). A number of UNICELLULAR organisms, such as microsporidia,parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.[1] To date, only one eukaryote, Monocercomonoides, is known to have completely lost its mitochondria.[2] The word mitochondrion comes from the Greekμίτος, MITOS, "thread", and χονδρίον,chondrion, "granule"[3] or "grain-like". Mitochondria generate most of the cell's supply of adenosine triphosphate (ATP), used as a SOURCE of chemical energy.[4]_____thanks

Definition of BARTHOLIN's gland. : either of two oval racemose glands lying ONE to each side of the LOWER part of the vagina and secreting a lubricating mucus. — called also gland of Bartholin, greater VESTIBULAR gland. — compare cowper's gland.

piratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animalsand plants. The anatomy and physiology that make this HAPPEN varies greatly, depending on the size of the organism, the ENVIRONMENT in which it lives and its evolutionary history. Inland animals the respiratory surface is internalized as linings of the lungs.[1] Gas exchange in the lungs occurs in millions of SMALL air SACS called alveoli in mammals and reptiles, but atria in birds. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood.[2] These air sacs communicate with the external environment via a system of airways, or hollow tubes, of which the largest is thetrachea, which branches in the middle of the chest into the two main bronchi. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into NUMEROUS smaller tubes, the bronchioles. In birds the bronchioles are termed parabronchi. It is the bronchioles, or parabronchi that generally open into the microscopic alveoli in mammals and atria in birds. Air has to be pumped from the environment into the alveoli or atria by the process of breathing which involves themuscles of respiration.

lus causes an ACTION or response, LIKE the ringing of your alarm clock if you didn't sleep through it. Stimulus is a word OFTEN used in biology — something that causes a reaction in an organ or cell, for example. ... For more than one stimulus, use stimuli, not stimuluses.

es have ONE of the most unique reproductive strategies in the PLANT world. Mangroves are viviparous (bringing forth live young), just like most mammals. Rather than producing dormant resting seeds like most flowering plants, mangroves disperse propagules via water with varying degrees of vivipary or embryonic development while the propagule is attached to the PARENT tree.The red mangrove flowers mostly during the summer months. The long cigar shaped propagules are often found hanging on the tree all year long. The black mangrove flowers all summer long with the lima bean shaped propagules PRODUCED during late summer and early fall. The white mangrove flowers mid to late summer with small green pea shaped propagulesproduced a month later.

e here your answer ☺☺_______ Analogous ORGANS: The organs having the same functions but different in structure, origin and constituting parts are called analogous organs. For example, the wings of BATS and the wings of birds are analogous organs as Their ORIGINS, designs , structure and components, are different, but they have a common USE for flying_____Homologous organs : The organs having the same structure, origin and constituting parts but different functions are called homologous organs. the forearms of a horse and the hands of human.______

er is:The trachea serves as a passageway to allow passage of air from the region of the voice box to the main RESPIRATORY channels (bronchi) which enter the lungs.The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body's airway and has the vital FUNCTION of providing air flow to and from the lungs for respiration.The trachea is a rigid tube that CONDUCTS air from your larynx to your bronchi. The trachea's rigidity is maintained by a SERIES of cartilaginous rings arranged along itslength called C-shaped cartilage rings. The inner surface of your trachea is lined by a mucus membrane, which is itself covered with cilia.
