(3)i) Epiglottis and sealing of the respiratory passage during swallowingii) C shaped cartilage rings and prevention of collapsing of trachea during breathingiii) Alveoli and absorption and exchange of gasiv) PLEURAL cavity and lubrication v) Diaphragm and separation of thoracic and abdominal cavity(4)i) The work of BREATHING is done by the diaphragm, the muscles between the ribs (intercostal muscles), the muscles in the neck, and the abdominal muscles.ii) During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward). This compresses the abdominal cavity, raises the ribs upward and outward and thus expands the thoracic cavity. This expansion draws air into the LUNGS.iii)The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).iv) (1) The residual VOLUME (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty. ... Therefore, there is always some air remaining in the lungs (2) Dead space is the volume of air that is INHALED that does not take part in the gas exchange, because it either remains in the conducting airways or reaches alveoli that are not perfused or poorly perfused(5)Write that yourself(•‿•)

Much like the INSULATION AROUND the wires in ELECTRICAL systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon. This myelination, as it is called, can greatly INCREASE the speed of signals transmitted between neurons (known as action POTENTIALS).Explanation:hope it helps you good day!!

plzzzz mark this as a brainleast answerExplanation:HPS stain. Grey matter (or GRAY matter) is a major component of the CENTRAL nervous SYSTEM, consisting of NEURONAL cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

The UPPER heart CHAMBERS (ATRIA) contract. The AV node sends an impulse into the ventricles. The LOWER heart chambers (ventricles) contract or PUMP. The SA node sends another signal to the atria to contract, which starts the cycle over again.

tWhat is the nature of environmental problems? This ARTICLE attempts to illuminate this question by exploring the relationship between environmental ETHICS, environmental problems and their solution. It does this by examining and criticising the argument contained in a recent issue of Environmental Values asserting that environmental ethics does not have a role to play in solving environmental problems. The major point made in this rebuttal article is that environmental problems are essentially normative in nature. Therefore, normative discourse, and environmental ethics in particular, do have a crucial role to play in environmental THOUGHT and action. The discussion concludes with the judgment that a failure to recognise this essential contribution of normative discourse to environmentalism by committing to a CONSERVATIVE empirical reductionism of environmental problems is detrimental to the necessary ethical and social change required to save the WORLD.

MARK ME AS BRAINLIEST Explanation:A useful analogy is to think of a neuron as a tree. A neuron has three main parts: dendrites, an axon, and a cell BODY or SOMA (see image below), which can be represented as the branches, roots and trunk of a tree, RESPECTIVELY. A dendrite (tree branch) is where a neuron receives input from other CELLS.

In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is CALLED a BLASTOCYST. It is by this adhesion that the embryo receives oxygen and nutrients from the MOTHER to be able to grow. I hope it helps u PLZ mark me as a brainliest plz
