Kipish [7]
The answer is (A) stabilizing selection. Stabilizing selection favors the average in a population. In this case, babies that are born at a normal body weight, or an average between the two extremes of underweight and large, tend to have more favorable outcomes.

How do ETS reactions produce ATP?
Norma-Jean [14]

ATP synthesization -  Simple and complex lipids or carbohydrates are used to produce ATP through redox reactions. After the hydrolysis of complex carbohydrates, glucose and fructose are formed and the triglycerides are metabolized to form glycerol and fatty acids. ATP is then synthesized by oxidative phosphorylation and photophosphorylation during the energy production with in the living organisms. ATP production usually takes place in the mitochondria of the cell.  The important pathways by which ATP is generated are glycolysis, the citric acid cycle (or the Kreb’s cycle), and the electron transport chain (or the oxidative phosphorylation pathway).  In these three cycles of  cellular respiration  adenosine diphosphate (ADP) is converted  to ATP and energy is released  from molecules.

Which genetic mutation can be passed to the offspring?
Kitty [74]

Answer:

A gamete containing an extra chromosome is formed.

Explanation:

Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.

Son músculos antagonistas (unos realizan flexión y otros extensión) los siguientes: * 5 puntos Trapecio- deltoides Bíceps- tríce
Lena [83]

Answer:

Bíceps- tríceps

Explanation:

Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae  y el bíceps (antagonista) se relaja.

elena55 [62]

\huge\mathfrak {Answer}

During telophase, membrane-enclosed vesicles derived from the Golgi apparatus migrate to the center of the cell where the metaphase plate used to be and fuse to form a cell plate. Eventually, the growing cell plate fuses with the existing plasma membrane, producing two daughter cells, each with its own plasma membrane.
