Biology

Verdich [7]3 years ago
6 0

Answer:

The correct answer is "Absolute Magnitude".

Explanation:

Absolute magnitude is a measure of luminosity applied to celestial objects such as stars. In contrast to other measures such as apparent magnitude, absolute magnitude uses a standard distance from Earth as scale, particularly,  the distance of exactly 10 parsecs (32.6 light-years). The symbol of absolute magnitude is "M", and in the case of stars, it usually has a measure from −10 to +17.

Challenge: A chemical equation is balanced when each side of the equation includes the same number of each type of atom.
nirvana33 [79]
If the reactants are the same the equations are balance but if the reactants are not the same you have to make them balance, however if the reactants are not balance  in order to balance the equation you need to use coefficient to balance the reactants and products of particular chemical reaction.
yet for Photosynthesis the equation 
CO_2 + H_2O => C_6H_12O_6 + H_2O + O_2
Find the ugliest Compound in equation and do not balance first the repetitive Element.
A)So the ugliest one is C_6H_12O_6 and the C is not repetitive and have six atoms so there fore we multiply 6 as coefficient with carbon dioxide.
6CO₂+ H₂O → C₆H₁₂O₆+H₂O+O₂ but oxygen will get 12 atoms because is to all Carbon dioxide.
B) Then we have carbon balanced then we are going to balance Hydrogen, yet on product side it have 14 but on the reactant side it have 2 but Oxygen on product side is 9 there but on reactant side we have 1 so there fore we have to multiply water on reactant side by 12 and on product side multiply water with six and in addition multiply oxygen with 6 which land you at:
6CO₂+ 12H₂O → C₆H₁₂O₆+6H₂O+6O₂.
so we will have 24 hydrogen and 24 oxygen on both sides. 
Hope that helps you.

In which location would the rate of soil erosion most likely be higher than the rate of soil formation?
xz_007 [3.2K]

Answer:

C. A steep slope

Explanation:

Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.

Agents of erosion are wind, water, glacier and gravity.

Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.

On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.

Investigators have arrived at a crime scene and are ready to search for evidence. What needs to happen next?
denpristay [2]

Answer: C . They should map out a grid to systematically look for evidence.

Explanation:

As a crime has been committed, the investigators do not need a search warrant so there is no need to ask a Judge for one so option A is incorrect.

It is best if evidence is searched for in different locations not just the primary scene so option B is incorrect.

Setting up a grip to enable the systematic analysis of evidence is their most likely course of action so option C is correct.

Even if the case is not complicated, evidence still needs to be searched for so option D is wrong.
