Answer:
The correct answer is - 1:2:1 for black : blue : white chicken.
Explanation:
We know that color of the feather is a trait of the chicken that shows the codominance type of inheritance pattern where both forms of the trait are dominant and make a mix of the forms. In this case, blue is heterozygous BW and black BB and white is WW, then crossed between BW with BW
gametes: B, W and B, W
Punnett
B W
B BB BW
W BW WW
thus, the phenotypic ration is - 1 black : 2 blue : 1 white
Fungi has a cell wall but no chloroplasts.
Your answer is prophase 1. These stages listed in order are prophase 1, metaphase 1, prophase 2, metaphase 2. Hoped this helped.
Answer:
Helium
Explanation:
We know that this atom has two positive particles on the nucleus (protons) with two neutral particles (neutrons). We can also see that it hass two electrons on the orbitals. Knowing this, we can say that the element is Helium.
Helium has a relative atomic mass of 4 and it's atomic number is 2. The atomic number is equal to the number of protons and electrons the atom has, and the atomic mass can be used to calculate the number of neutrons:
Relative atomic mass = Neutrons + atomic number
So we know that:
Neutrons = relative atomic mass - atomic number
Neutrons = 4 - 2 = 2.
