What is the diploid number of chromosomes for a normal bug karyotype?
what is the 2n chromosome number for a normal bug
Why does the nucleus of a fruit fly contain less chromosomes than the nucleus of a human?
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
Which Forms cells with half the chromosome number of the parent cell?
Sex cells, such as sperm and egg cells, are formed through the process of meiosis, which results in cells with half the chromosome number of the parent cell. This reduction in chromosome number is essential for sexual reproduction and ensures that when the sperm and egg cells combine during fertilization, the resulting zygote will have the normal chromosome number.
The normal species chromosome number is called the what number?
During cell division the parent cell splits to form what 2 cells
What process union of egg and sperm restores chromosome number?
The union of an egg and sperm restores the chromosome number through the process of fertilization. During fertilization, the haploid egg and haploid sperm fuse to form a diploid zygote, which contains the full complement of chromosomes (46 in humans). This restores the normal chromosome number in the resulting offspring.

What is the chromosome number of gamete?
They have half the number of the somatic (parent) cell. So if a parent cell had 46 chromosomes in its nucleus, then its gamete would have 23(one chromosome from each pair).
Which sequence of terms represents a decrease from the greatest number of structures to the least number present in a cell?
gene,chromosome THEN nucleus :) HOPE YOU DO WELL !!
Do isotopes have a nucleus?
Yes. Isotopes are simply normal elements with a different number of constituent neutrons in their nucleus. All isotopes have a nucleus with an identical number of protons to its element.

What is the atomic number always equal to?
The atomic number reflects the charge number of the nucleus. It is always equal to the number of protons found in the nucleus.
What is an aton with a different mass number than normal?
An isotope of the element. The mass number is the number of protons and neutrons in the nucleus.
If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes
How does the alternation of meiosis and fertilization in the life cycles of sexually reproducing organisms maintain the normal chromosome count for each species?
Simple, Meiosis reduce the chromosome number in half while fertilization doubles the chromosome number. n=chromosome number Meiosis = 2n (primordial germ cells) ----> n (sperm cell/egg cell/polar bodies) Fertilization = sperm (n) + egg (n) ----> 2n (zygote)
Which sequence of terms represents a decrease from the greatest number of structures to the least numbers of structures present in a cell?
gene,chromosome THEN nucleus :) HOPE YOU DO WELL !!
