Sabemos que la vida comenzó hace al menos 3.500 millones de años, porque esa es la edad de las rocas más antiguas con evidencia fósil de vida en la tierra. Estas rocas son raras porque los procesos geológicos posteriores han remodelado la superficie de nuestro planeta, a menudo destruyendo rocas más viejas y creando otras nuevas (lo siento si es un amor incorrecto, marque como más inteligente si es correcto).
Out of the following given choices;
A) her sex.
B) how tall she is.
C) how long her hair is.
D) the color of her eyes.
The answer is C. The length of hair is not determined by
genetics but rather by the time period of the growth phase (anagen phase) of
the hair follicle, before shedding in the telogen phase. The longer the anagen
phase the longer the hair will be before shedding. The hair on the head has
longer anagen phase compared to hair in regions such as the eyebrows.
No abiotic things are non-living, and cells are living.
The best answer is C - to break down food into nutrients.
The digestive system breaks down food into its simplest form that cell are able to utilize for energy. Food is broken down into its monomer units. Proteins are broken down into amino acids, lipids are broken down into fatty acids and glycerol and carbohydrates are broken down into glucose.
Glucose is then absorbed into the blood and transported to every cell in the body. The cells take in glucose and use it as fuel and raw material in the process of cellular respiration. From one molecule of glucose, 36 to 38 molecules of ATP ( the form of energy used by cells) are produced.
