The answer is: A - Strong base

Explanation:

The pH scale goes from 1 - 14 with 1 being the most acidic, 7 being neutral, and 14 being the most basic. Since 13 is right below 14 (which is the most basic), it is a strong base.

How is an oxidation half-reaction written using the reduction potential chart? How is the oxidation potential voltage determined
insens350 [35]
Oxidation  half  reaction  is  written   as    follows when  using  using  reduction potential  chart
example  when  using  copper  it is  written  as  follows
CU2+   +2e-  --> c(s)  +0.34v
 oxidasation  is the  loos  of  electron  hence copper oxidation  potential  is  as  follows
cu (s)  -->  CU2+   +2e    -0.34v

Which best explains what happens to the carbon atoms in carbon dioxide during photosynthesis?A They are incorporated into molecu
Mademuasel [1]

Answer:

A They are incorporated into molecules of sugar.

Explanation:

Photosynthesis is the metabolic process whereby sugar molecules are synthesized by plants in the presence of sunlight (light energy). For this process to occur, carbon dioxide (CO2) and water (H2O) are needed as reactants from external sources. Hence, the photosynthetic equation is as follows:

6CO2 + 6H2O → C6H12O6 + 6O2

According to this question, the carbon atoms in carbon dioxide are incorporated into sugar molecule (glucose). It takes 6 carbon atoms to produce one glucose molecule (C6H12O6). This process involves series of reaction in the light-independent stage of photosynthesis to occur.

In cucumbers, green skin (G) is dominant to striped skin (g). If a farmer crosses a heterozygous (hybrid) cucumber with a homozy
Elena L [17]

Answer:

Half will be green and half will be striped

Explanation:

Given green skin (G) is dominant to striped skin (g).

Cucumber 1 : Heterozygous (Gg)

Cucumber 2 : Homozygous striped (gg)

When Gg X gg :

     G      g

g   Gg   gg

g   Gg   gg

Half of the offspring will have Gg genotype so they will be green. Other half will have gg genotype so they will be striped.
