The correct answer is c trachea
When a bend in a river gets cut off...
when a homozygous white rabbit (bb) is crossed with a heterozygous black rabbit (Bb). what proportion of white rabbits would the offspring have?
Answer:
Based on the Mendelian fashion cross,
bb is hetezygote reccessive.(white)
Bb is heterozyote dominant.(black)
Therefore,the the cross to show the proportion is below
Bb,Bb,bb,bb,
2 blacks(hetero zygote blacks) and 2 white.(homo zygote whites)
thus 2 of the offspring will be white, in 50%, of the number of offspring
Explanation:
Answer: For flowering plants, fertilization occurs through a process known as double fertilization. Unlike most plants, double fertilization enables the new seed to grow into a new plant and have a food source to begin growing. Double fertilization occurs within the female part of a plant, the pistol.
explanation: When pollen is formed by the anther, or male part of a plant, it will blow in the wind or attach to an organism that carries it to the top of the pistol, known as the stigma. Once the pollen attaches to the stigma, the pollen germinates and forms a pollen tube that extends into the ovary. Once formed, two sperm cells will be released and fertilize both the egg and the two polar nuclei of the plant to form the zygote and endosperm, respectfully.
