As an Astronaut goes out into space, her mass REMAINS THE SAME and her weight DECREASES.
When one travels away from the earth surface, one's mass remains the same but the weight decreases as the gravitation pull decreases.
The experience of weight on earth is as a result of the counteracting forces acting one's body and the ground. When one is in the space, this counteracting force is removed because the ground is no longer pushing back on one's body. Thus, one's weight will decrease in space because gravitational pull is lower above the earth's surface.
Space, environment, weather, population increase and decreas
1) As blood groups A and B are equally dominant so the individual will express both characteristics in the phenotype.
Notice how in all the 3 other examples the organism is only expensive 1 version (allele) of each gene. For example the mouse with brown fur may have 2 brown fur alleles (and so would have to express this characteristic even if it was recessive) but it could have 1 allele which is less dominant than the brown, in which case brown would be expressed. In this case the alleles were not co-dominant.
Answer:
Differentiate between tricuspid valve and bicuspid valve
<u><em>The tricuspid valve is positioned between the right atrium and right ventricle, whereas the bicuspid valve is located between the left atrium and left ventricle. Furthermore, the tricuspid valve has three cusps, whereas the bicuspid valve has only two. Valve that connects the heart's left atrium and left ventricle.</em></u>
hope this helps!
Explanation:
In F2 the bonding is pure covalent, with the bonding electrons shared equally between the two fluorine atoms. In HF, there is also a shared pair of bonding electrons, but the shared pair is drawn more closely to the fluorine atom. This is called a polar covalent bond as opposed to the pure covalent bond in F2.
