Una membrana semipermeable es una especie de filtro pero com un tamaño de agujero tam pequeño que filtra las partículas a nivel molecular V o F justifica las Falsas
2- cuando las partículas de dos líquidos separados por un membrana semipermeable, pasan del medio de menor concentración se dice que ocurre por ósmosis V o F
3- la producción de zumos concentrados se realiza mediante osmosis simple
V o F?
respondan gente..

Can someone me with this and tell me what’s fracking and what does it have to do with carbon, carbon dioxide, or fossil fuels?

How to farmers could ensure that they only grow white flowers

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies. what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
