Answer:
Non-random alignment of chromosome pairs.
Explanation:
Meiosis is when the mother cell or the diploid cell replicates into four haploid cells and divides twice; leaving just two haploid cells that contains only half the number of chromosomes.
Through meiosis, we get the gametes which are the cells that we use to fecund and reproduce ourselves (ovules and sperm); each cell contains half the chromosome content. To allow the combination of genetic information by cross-linking the chromosomes there need to be 23 chromosomes from the father and 23 from the mother to form one individual with 46 chromosomes.
Leaving us with non-random alignment of chromosome pairs as if it was random that would mean that it wouldn’t matter how many chromosomes each parent provides, also, the cells have to be haploid in order to continue the process.
I think it is called <span>ethnocentrism. Hope it helps!</span>
Answer:
Anoche bebí una cerveza artesanal, hecha por un amigo (1 D.) que produce su cerveza con maltas provenientes de Querétaro (3 I.D.).
Desayuné pan, comprado en una tienda que no lo produce (1 D, 2 I.D), con mermelada de zarzamoras, hecha por un amigo (1 D.) que compró larga cantidad de zarzamoras - es temporada de zarzamoras.
Luego bebí un café, con café orgánico de Chiapas que una asociación de comercio justo me provee (5 D, 3 I.D).
La comida eran nopales (1 D, 3 I.D) con queso oaxaca. Los nopales (familia de cactus) crecen por doquier en nuestro estado. El queso oaxaca (1 D. 4 I.D.) compramos en una tienda colectiva y no está hecho en Oaxaca sino aquí.
La cena consistió de unos tamales oaxaqueños (2 D, 5 I.D) con hojas de plátano,masa de maíz, mole y pollo. sólo el último ingrediente tiene dudosa procedencia.
Ah! Compré una botella de limoncello (licor italiano de limon) que un amigo (1 D) francés hace con su propia cosecha de limones.
Explanation:
D = Directo
I.D. = Indirecto

Answer:
Human activities cause erosion in a number of ways across the globe. Research has shown that humans are responsible for more erosion than natural processes.
1. Deforestation - it drastically causes an increase in the erosion rates as plant roots hold soil tightly that prevent erosion due to wind and water but cutting trees increases it. Plantation reduces erosions.
2. Agricultural practices have an impact on erosion rate. This promotes the likelihood of erosion, as the soil can be transported more easily due to wind and water.
3. Growing monocultures - one type of crop leads to an increase in erosion as nutrition and components of soil are drastically reduced. r
4. chemical fertilizers in agriculture can also increase soil erosion, as these chemicals damage, the flora, and fauna that live in the soil.
5. Mining/walking or biking and other practices can also contribute to erosion gradually over time. Mining exposed soil during this process.
