it dominates the phenotype

Explanation:

D, because when you have one recessive and one dominant allele, then the dominant one will always over power the recessive. That's why the majority of people have brown eyes, it's because brown eyes are a dominant trait whereas blue or green eyes are recessive.

Explain how astronomers use spectrographs to identify the composition of a star.
Gwar [14]
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
hope this helps you! :-)

Compared to the nonmetals in Period 2, the metals in Period 2 generally have larger
konstantin123 [22]
The answer is atomic radii; the size or radii of an atom increases from left to right, versus the ionization energies and electronegativities of atoms which increase from right to left.

A 1.24g sample of a hydrocarbon, when completely burned in an excess of O2 yields 4.04g Co2 and 1.24g H20. Draw plausible struct
arsen [322]

Answer:

Plausible structure has been given below

Explanation:

  • Molar mass of CO_{2} is 44 g/mol and molar mass of H_{2}O is 18 g/mol
  • Number of mole = (mass/molar mass)

4.04 g of CO_{2} = \frac{4.04}{44}moles CO_{2} = 0.0918 moles of CO_{2}

1 mol of CO_{2} contains 1 mol of C atom

So, 0.0918 moles of CO_{2} contains 0.0918 moles of C atom

1.24 g of H_{2}O = \frac{1.24}{18}moles H_{2}O = 0.0689 moles of H_{2}O

1 mol of H_{2}O  contain 2 moles of H atom

So, 0.0689 moles of H_{2}O contain (2\times 0.0689)moles of H_{2}O or 0.138 moles of H_{2}O

Moles of C : moles of H = 0.0918 : 0.138 = 2 : 3

Empirical formula of hydrocarbon is C_{2}H_{3}

So, molecular formula of one of it's analog is C_{4}H_{6}

Plausible structure of C_{4}H_{6} has been given below.

Is CO2 a covalent or ionic bond? will give brainliest for the correct answer​
NeX [460]

Answer:

covalent bond

Explanation:

a covalent bond happens between two nonmetals

a ionic bond happens between a metal and a non metal

CO2 is a bond between carbon and oxygen

carbon and oxygen are both non metals therefore CO2 is a covalent bond
