Answer:
b. pieces of DNA is the correct answer.
Explanation:
A gene is a piece of DNA and it is present in the nucleus of all cell's
The function of the gene is to codes for a specific type of protein.
Genes convey the message that determines our characteristics
Genes are called as a functional unit of genetics.
Answer:prophase----the chromosomes shorten and thicken.the nuclear membrane has open up and the nucleolus has disappeared
Metaphase----the chromosomes migrate to the central plane of the cell and attach to the spindle fibres microtubules
Anaphase---the chromatids of each chromosomes part and move towards opposite poles of the spindle as the spindle fibres shorten
Telophase----the chromatids are in the polar end of the spindle .the spindle breaks down,the centrioles replicate,the nuclear membrane is reformed,the chromosomes gradually uncoil.
Explanation:
It is when the inclination of atoms of a dissolvable to go through a semipermeable layer from a less amassed arrangement into a more focused one, evening out the fixations on each side of the film.
I hope the answer will help you.
The correct answer is an F1 generation.
The parent plants in the experiments conducted by Mendel are considered as the P (for parent) generation. The F1 stands for the first filial generation, which was obtained on cross-pollinating the parent plants. The F2 stands for the second generation, which is attained after self-pollinating the F1 generation plants.
Cell membrane is the largest. Most important. Of course all cells are different and shape size also. they all have difference.
