Answer:
the orientation of Earth's tilt with respect to the sun – our source of light and warmth – does change as we orbit the sun. In other words, the Northern Hemisphere is oriented toward the sun for half of the year and away from the sun for the other half.
Explanation:
Answer:
Alleles for feather colour exhibit incomplete dominance or co-dominance.
50% gray offspring + 50% black offspring
Explanation:
<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>
Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.
Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.
15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.
Bb x Bb = 1BB, 2Bb, and 1bb
Crossing the gray rooster (Bb) with a black hen (bb):
Bb x bb = Bb, Bb, bb, and bb
= 2Bb (gray):2bb (black)
50% of the offspring will be gray while the remaining 50% will be black.
b)1 unicellular- means one cell
Answer:
Answer b) The result of the experiment identifies that the color of the egg donor branch (parent) prevailed and assigned the color of the offspring.
-The female parental branches that were pure green or pure white had children of pure green or pure white, respectively.
- The female parental branches that were variegated allow to obtain the three types of offspring.
It is evident that the chloroplast shows maternal inheritance.
The branch that is pure green will produce eggs with green chloroplasts that will give rise to a pure green offspring. Thus, a pure white branch will have offspring with ovules with an exclusive content of white chloroplasts and will give rise to a pure white offspring.
If a branch is variegated, it is combined, some with only functional chloroplasts, some with only non-functional chloroplasts, and some with a mixture of chloroplasts. All three types of cells can give rise to ovules, leading to green offspring, white offspring, and variegated offspring.
Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.
