Recent research provides evidence that brushing your teeth with baking soda increases your risk of frabjuous cell basocarcinoma
Natali5045456 [20]
Before making a decision as to whether you should throw away your baking soda toothpaste or not, you should first determine the basal risk of developing frabjuous cell basocarcinoma. If the chances of developing this are already negligible, then a 700% increase is no cause for alarm.

In mitosis the spindle fibers connect to what
IrinaK [193]

Answer:

During mitosis, the spindle fibers are called the mitotic spindle. ... Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores.

Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where duplicates are linked. Identical, joined copies of a single chromosome are known as sister chromatids

A heterozygous, three-horned alien from Mercury has met and fallen in love with a four-horned alien from Jupiter. What would hap
Gnesinka [82]
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen.  If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
