Water "beads up" on synthetic fabric such as polyester but binds to cotton. what is the most likely explanation for this?'
choli [55]
The water beads up on synthetic fabric comparable to polyester but impasses to cotton because polyester is nonpolar while cotton is polar. In addition, nonpolar covalent bonds are a kind of chemical bond where two atoms portion a pair of electrons with each other while polar covalent bonding is a type of chemical bond where a pair of electrons is unevenly shared among two atoms.

Calculate the surface-to-volume ratio of a spherical cell 15mum in diameter and of a cell 2mum in diameter. What are the consequ
Marina CMI [18]

Answer:

For calculating the surface to volume ratio for a spherical cell,  

Surface area (S) = 4πr²

Volume (V) = 4πr³ / 3

Ratio = S / V = 4πr² / 4πr³ / 3 = 3 × 4πr² / 4πr³

= 3/r

1. 15 micrometer diameter = Ratio = 3/7.5 = 0.4

2. 2 micrometer diameter = Ratio = 3/1 = 3

The cells exhibiting high surface to volume ratio shows enhanced metabolic activity. Shows easy uptake of oxygen, nutrients, water, and also the excretion of waste as they possess large surface.

Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por
sammy [17]

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).
