A substitution of thymine to adenine in one DNA base sequence can cause a particular disorder in blood cells. When this occurs, the blood cell shape changes into
a crescent, rather than the normal round shape. The DNA sequence change is shown
below.
Normal: CTT
Mutated: CAT
Which statement BEST explains how the change in DNA leads to this disorder?
The mutation prevents the production of all proteins in the blood.
The mutation prevents the production of the protein.
The mutation causes extra proteins to be made by the cell.
The mutation causes a different amino acid at this location in the protein.

answer; i believe the answer is hydraulic action;

there’s no image attached but i can if you want: )

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

answer >   yes we do, women; have three holes, urethral opening(pee hole, vagina, and the women pee/girls pee out of the urethra like the men do; only they have a single opening to pee/ejaculate.   (sorry if i'm too forward with this, but this is for a biology class, isn't it? )

hope that !         : )
