Answer:

The correct answer would be C) 75% large-toothed and 25% small-toothed.

It can be explained with the help of the law of dominance which states that the dominant allele expresses itself completely over the recessive allele in the heterozygous condition.

So, the genotype TT, as well as Tt, will result in the production of dominant trait or character in the offspring.

Thus, three (1 TT and 2 Tt) out of four offspring would have large teeth and only one offspring (tt) would have small teeth.

Hence, we can conclude that 75% of the offspring will have large teeth and only 25% will have small teeth.

Compare the structure and function of the human body system to a nonliving system

CaHeK987 [17]

The human body has living cells that interact with other living cells (Food) and inorganic cells (Salt, Oxygen). It also has a lot of chemical reactions that simultaniously happen inside of it.
Inorganic systems usually do not interact with themselves, and the reactions are mostly exterior.

How many moles would there be in 100 g of glucose? In 500 g of glucose? SHOW WORK

vivado [14]

Answer:

a) 0.56moles

b) 2.78moles

Explanation:

The number of moles can be calculated by using the formula;

Mole (n) = Mass (M) ÷ Molar mass (MM)

For a glucose molecule, with chemical formula: C6H12O6

Where atomic mass of C= 12, H=1, O= 16

Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)

= 72 + 12 + 96

= 180g/mol

a) In 100g of glucose;

Mole = 100/180

Mole = 0.56moles

b) In 500g of glucose

Mole = 500/180

Mole = 2.78moles

I believe that a scientific journal would be the best way to communicate towards his other colleague's. The reason why I wouldn't say the internet is, although the internet is much faster compared to others, the internet can differ in in information, making it unreliable.
