Most cells in the human body have a nucleus containing 23 pairs of chromosomes. A small section of a chromosome that controls one particular character, e.g. eye colour, is called a gene and each chromosome carries hundreds of genes.umans have 23 pairs of chromosomes. They are in the nucleus of every human cell. Human genome. The complete sequence of all 20,000-25,000 human genes. That is, which chromosomes they are in and whereabouts the gene appears on that chromosome's piece of DNA. DNA. Deoxyribonucleic acid.
Corn plants will not be killed by frost unless temperatures get cold enough to kill the growing point that is 3/4 of an inch below the soil surface. So corn that has not emerged typically is well insulated from frost damage. So corn that has not emerged typically is well insulated from frost damage.
Corn requires a soil temperature of 50Â° F and soybean a soil temperature of 54Â° F, respectively, to germinate and grow. Temperatures below the optimum can cause seeds to remain dormant and become more vulnerable to diseases, insects, and animal predators.orn requires a soil temperature of 50Â° F and soybean a soil temperature of 54Â° F, respectively, to germinate and grow.
