I would say just O :) have a good day

Answer from: JaylenGuidish

Blood types O, A, and B are possible for the father.

Explanation: Since the mother has type A blood, there are two possible genotypes that she can have: AA or AO. Since her son has type O blood, he only has one genotype: OO.

For blood types,

Type A - AA or AO

Type AB - AB

Type B - BB or BO

Type O - OO

* A and B are dominant over O.

Now we have to do crosses between the mother and the father:

AA mother with AB father: child with type AA or type AB blood

AO mother with AB father: child with type AA, AO, AB, or BO blood

AA mother with OO father: child with AO blood

AO mother with OO father: child with AO or OO blood

AA mother with AA father: child with type AA blood

AA mother with AO father: child with type AA or AO blood

AO mother with AA father: child with type AA or AO blood

AO mother with AO father: child with type AA, AO, or OO blood

AA mother with BB father: child with type AB blood

AA mother with BO father: child with AB or AO blood

AO mother with BB father: child with AB or BO blood

AO mother with BO father: child with AB, AO, BO, or OO blood

The father can have blood types O, A, or B.

Answer from: Quest

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

Answer from: Quest

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.
