The correct answer is: d) begins later in life
Eggs or female reproductive cells are formed well before birth in a huge number (primordial oocytes). But, the number of oocyte decreases after birth constantly (there are 2 million oocytes at birth and 40,000 of them in puberty). At menopause, no egg cells are left.
On the other hand, the first sperms are formed only from puberty, but the production of those cells never stops.

Explanation:
Answer:C). A phospholipid bilayer with proteins
Explanation: A cell membrane is a phospholipid bilayer with proteins embedded in it. The fatty acyl chains of the phospholipids are non polar and hydrophobic while the phosphate groups are polar and hydrophilic. The hydrophobic regions of the phospholipids interact with each by facing each other, forming a bilayer with a fluid interior. The polar head groups face outward interacting with the external environment of the cell. Proteins are embedded in this bilayer and they float in this sea of phospholipids. Proteins anchored to the membrane through interactions between the hydrophobic regions of the phospholipids and the amino acid side chains of the proteins. These lipids and proteins swim laterally in each face of the bilayer but movement from one face of the bilayer to another is restricted.
Answer:

- <u>Músculos: </u>DELTOIDES, BICEPS, ADUCTOR, PECTORAL, GEMELOS, DORSAL, CUADRICEPS, IZQUIOTIBIAL, CORAZON, ABDOMINAL.
- <u>Articulaciones: </u>CODO, MUÑECA, CADERA, TOBILLO, HOMBRO, CRANEO.
Explanation:
Los huesos son órganos que tienen la función de dar estructura, protección y soporte al cuerpo. A los huesos se le unen los músculos, los cuales hacen que los huesos se muevan al contraerse estos. Las articulaciones unen los huesos entre sí y permiten junto con los músculos el movimiento del cuerpo y de sus diferentes partes.
