A. excrete sodium ions, B. decrease ECF.

Explanation:

We study about the role of sodium and water retaining hormones in controlling extracellular volume. Several natriuretic hormones may also contribute to the volume regulation. One of the most important natriuretic hormone is atrial natriuretic peptide (ANP). It is a peptide hormone and is released by the cardiac atrial muscle fibers.

Overstretching of atria which can result from excess blood volume, is the stimulus for the release of ANP. Once released it enters into circulation and acts on kidneys to increase the glomerular filteration rate. It also decreases the absorption of sodium from collecting ducts. In other words it increases the secretion of Na+ along with water thereby reducing the blood volume and volume of ECF.

The excess loss of salt along with water helps to compensate for the extra blood volume.

ANP or atrial natriuretic factor (ANF) opposes RAAS i.e Renin Angiotensin Aldosterone System.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;

Mantle convection is the slow creepingmotion of earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.[1][2] the earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. this hot added material cools down by conduction and convection of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4] while in other regions, this material is impeded from sinking further, possibly due to a phase transition from spinel to silicate perovskiteand magnesiowustite, an endothermic reaction.[5]the subducted oceanic crust triggers volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6] and mantle plumes.[7]it is because the mantle can convect that the tectonic plates are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the hadean period, resulting in gravitational sorting of heavier molten iron, and nickel elements and sulphides in the core, and lighter silicate minerals in the mantle.
