Cellular respiration gives off CO2
1. A disease cause by a very small genetic change. Most cases result from the deleting of three bases in a gene for a protein called cystic fibrosis transmembrane changes which in a gene's DNA sequence can change proteins by altering their amino acid sequences which may affect one's phenotype.
2. It causes a mutation in the number of chromosomes, either extra chromosomes or missing chromosomes. Nondisjunction during meiosis can cause chromosomal disorders , such as a trisomy 21 (down syndrome) , Tuners syndrome , and Klinefelter's syndrome. It is a monosomy of the X sex chromosome.
Answer: I don't have the picture you're looking at, but I can try to give you some clues to help you out.
Prophase is where the chromatids enter the cell and the chromosomes attach to the spindle fibers in the cell.
<u>Met</u>aphase: all of the chromosomes line up in the center of the cell (I use this trick I made up to remember this one: The chromosome will have <u>Met </u> the teacher's expectations when they line up in the center of the cell.)
Telophase: is where the sister chromatids go to opposite sides of the cell right before they split
Anaphase is when they finally split and are now classified as two different cells. One parent cell and one daughter cell.
I hope this helps you to solve your problem!

Answer:
The membrane potential is maintained in the cell due to the unequal distribution of the ions inside and outside of the cell. This membrane potential is important for the conduction of the nerve impulse.
The arrival of the stimulus triggers the action potential. The resting membrane potential is -70mV. This is maintained by the presence of potassium ions. The influx of the sodium ions result in the change in the membrane potential from -70mV to +30mV.
The option that is true of genes found on chromosomes is that D. they determine the inherited traits of an organism.
Genes are inherited - so those are the things that we get from our parents and other ancestors. It is easy to determine which of these genes a child is going to inherit - the doctors just need to take a look at the chromosomes, because genes are located there.
