Answer:
The atomic mass of carbon (C) is 12.0107 amu, so if you want to calculate the total mass in each molecule, you just need to multiply the number of carbon atoms in the substance by 12.017. In (a) there is one atom of C, (b) have also one atom of C, (c) have 12 atoms of C, and (d) have five atoms of C. Thus, the total mass (amu) of carbon is:
(a) 12.017 amu
(b) 12.017 amu
(c) 144.204 amu
(d) 60.085 amu
Answer:
A. is the correct answer because Boron has 3 electrons too,
All elements in Group 13 have three electrons in their outermost energy level. The two most popular elements in this group are Boron and Aluminum.
Answer:
Phenotype is : The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).
Explanation:
We come across differences shown by individuals of same species or we can say dis-similarity shown by offspring when compared to his/her parents .
When we cross parental generation , the gamete formation occur in accordance with Law of Segregation and then we get to see different combination of gametes that give rise to offspring with contrasting characters (In accordance with Law of independent assortment ).
After crossing we make conclusions by calculating the phenotypic and genotypic ratio of the cross .
Phenotype : It refers to physical expression of an organism or The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).
Phenotypic ratio of Monohybrid cross is always 3:1 .
Genotype : Refers to genetic constitution of an organism .
Genotypic ratio of Monohybrid cross is always 1:2:1 .
The fact that CO2 is released from oceans due to further rise in temperature is an example of a negative feedback.
A negative feedback is one in which the process that produces the feedback is interrupted. That is, the process is stopped as a result of the feedback received.
In this case, CO2 which leads to global warming dissolves in the ocean which serves a large sink for the gas. However, as the increase in ocean temperatures causes decrease in solubility of CO2, more CO2 is released leading to further temperature rise. This is an example of a negative feedback loop.
