Answer:
1) represented by a lower case letter
2) always masked by dominant genes
3) only expressed in the absence of a dominant gene
Explanation:
So if I take a black and a yellow marker- and tried drawing the yellow over the black- or the other way around- you'd still only see the black marker. The recessive trait is like the yellow marker. Now if I drew the yellow marker with another yellow marker you would see the yellow. I hope this helps!
Answer: mole fraction of methanol = 0.590
mole fraction of ethanol = 0.410
Explanation:
We are given:
Equal masses of methanol 
and ethanol 
are mixed.
let the mass be x g.
Calculating the moles of methanol in the solution, by using the equation:
Calculating the moles of ethanol in the solution, by using the equation:
To calculate the mole fraction of methanol, we use the equation:
To calculate the mole fraction of ethanol, we use the equation:
Thus mole fraction of methanol is 0.590 and mole fraction of ethanol 0.410 in three significant figures.
Answer:
The sum of the molar masses of each isotope of the element.
Answer:
Plants and animals are pH sensitive. The growth of plants is dependent on the nature of the soil. If the pH of the soil is greater than 7 and is alkaline, then the plants cannot grow in the soil.
Explanation:
Answer:
b. the layer of oxide formed on statues made of metal
Explanation:
Chemical weathering is a process whereby rocks are disintegrated or weathered causing a chemical reaction thereby leading to change in the parent rock constituents .
In chemical weathering a new substance is usually formed after the weathering takes place.
From the question the layer of statue made by metal will likely form oxides of those metals. Example Silver will react with oxygen to form an entirely new substance like silver(i)oxide.
