Answer:
Dominant
Explanation:
Let the allele for short tail trait be represented by "T" and allele for long tail trait be represented by "t"
When a short tailed mutant with genotype "tt" is mated with long tailed mouse, following offspring will be produced -
Tt * tt
Tt, Tt, tt, tt
so the ratio of short tailed and long tailed mouse is 1:1
Here it is given as 4:3 . Hence, there are chances that short tail trait is dominant
In the second generation , two short tailed mouse are crossed. The following offspring will be produced
Tt * Tt
TT, Tt, Tt, tt
The ration of short tailed and long tailed mouse is 3:1
Here it is given as 6:3 i.e 2:1 . Hence, short tail trait is dominant over long tail trait.
It wants to give up an electron so that i has eight outer electrons left from the previous shell
Answer:
Option 3,
Explanation:
In the process of cellular respiration, the sugar is oxidised to convert into carbon dioxide , water and energy molecule ATP (Adenosine Tri Phosphate)
If the above chemical reaction is represented mathematically it will be as follows -
The above reaction is a balanced chemical reaction representing cellular reaction
Thus, option 3 is correct
False, the Arctic National Wildlife Refuge can not provide us with nearly on hundred years worth of oil.
Hi there!
Meiosis is a type of reproduction where two divisions occur. It is when gametes, sex cells, divide. In prophase of meiosis, it is similar to that of mitosis, as in the spindle fibers develop as well as centrioles. First, homologous (pairs) of chromosomes line up in the center of the cell. Next, spindle fibers pull the pairs apart, leaving one chromosome of each pair on each side. Then, the nuclear material divides as the spindle fibers and centrioles go away. Lastly, the cytoplasm divides, leaving two cells. Meiosis two starts out with prophase again. In prophase, the DNA condenses and forms short chromosomes as well as spindle fibers and centrioles developing. Next, the chromosomes (there is only one chromosome, made up of two sister chromatids) line up in the center of the cell. Next, the spindle fibers pull the chromosomes apart, pulling one chromatid to each side of the cell. Then, the nuclear material divides and the spindle fibers and centrioles disappear. Lastly, the cytoplasm divides, leaving four cell in total.
Hope this helps!! :)
