SE LE CONOCE COMO IRRITABILIDAD
Los seres vivos tienen la capacidad de responder a una variedad de estímulos tanto del medio exterior como del medio interno. Esta capacidad de respuesta se denomina irritabilidad, porque es diferente a otro tipo de respuestas que se observan en la naturaleza.
I will think it’s B.... hope it helps!
Answer:
<em>Competition without division of resources may lead to extinction.</em>
Explanation:
Some species are better adapted to live in an environment as compared to other species. If resources become scarce then the species with better traits might take up all the resources of a species which are not better adapted. This will cause the species with unfavourable traits to become extinct. To survive in an environment, an organism needs to change and adapt according to the conditions of the environment. Otherwise, the species will become extinct.
Answer:
Alleles for feather colour exhibit incomplete dominance or co-dominance.
50% gray offspring + 50% black offspring
Explanation:
<em>It means that the alleles for feather colour in the hen exhibit incomplete dominance or co-dominance over one another.</em>
Assuming the allele for white colour is B, white colour will be b while the heterozygote Bb gives the gray phenotype.
Gray rooster + gray hen = 15 gray chicks, 6 black chicks and 8 white chicks.
15:6:8 is roughly 2:1:1 which is phenotypic ratio obtainable from crossing two heterozygous individuals as pointed out by Mendel.
Bb x Bb = 1BB, 2Bb, and 1bb
Crossing the gray rooster (Bb) with a black hen (bb):
Bb x bb = Bb, Bb, bb, and bb
= 2Bb (gray):2bb (black)
50% of the offspring will be gray while the remaining 50% will be black.
