Answer:
C
Explanation:
A toboggan is a simple sled traditionally used by children. It is well adapted to sliding down open slopes, where its large surface rides easily on loose, fluffy snow.
Answer:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder
Load 12 ul on the gel.
Explanation:
DNA Ladder concentration = 1000 ug/ml
1000 ug DNA in 1 ml DNA Ladder solution → 150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution
6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)
An appropriate volume to load on an average agarose gel is 12 ul, so:
2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul
But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul
And load half of that solution (12 ul) on the gel.
It shows the evolution of certain species through the bone structures of the fossils.
Circulatory system pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.
The female duct system is composed of the following organs:
a. Fallopian tubes - this is like a bridge that serves as a passage way for eggs from the ovaries to be delivered to the uterus.
b. Ovaries - are egg cells within the female reproductive system that when mature may develop into a fetus or become a regular menstrual period for women.
c. Uterus - This is where the mature ovaries begin to develop and start to form new life.
