Answer:
<u><em>A diploid cell becomes haploid during Meiosis I and is completed after Telephase I. These homologous chromosomes (from mom & dad, all duplicated) pair up during prophase I forming tetrads. The pairs of homologs line up on the metaphase plate during metaphase I.</em></u>

Answer:
<em>The correct option is B) the availability of money</em>
Explanation:
Potable water can be described as the water which is safe to drink. Nowadays, with the rapid industrialization progress, it is important to process water so that it can be used for human consumption. The processing of water to make it clean enough requires money. The more money a community will have, the more machinery and plants it will be able to set up for the processing of water.
Answer:
Check the explanation
Explanation:
Average weight before selection =2.5 kg
Average weight after selection = 5.5 kg
Average weight in the next generation =3.5kg
= 
R= Mean weight in the next generation - mean weight before selection
= 3.5-2.5 = 1.0
S= Mean weight after selection -mean weight before selection
= 5.5 - 2.5 = 3.0
=
=
= 0.33
<h2>Answer:</h2>
<h2>Mesophlly</h2>
1: Structure of a leaf (cross-section): Photosynthesis takes place in the mesophyll. The palisade layer contains most of the chloroplast and principal region in which photosynthesis is carried out.
Answer:
Over the ages the tendency of crop improvement efforts has been to select varieties with traits that give the highest return, largely by concentrating on genetic strains that combine the most desirable traits. The resulting homogeneity and uniformity can offer substantial advantages in both the quantity and quality of crop harvested, but this same genetic homogeneity can also reflect greater susceptibility or pathogens. Thus it appears the more that agricultural selection disturbs the natural balance in favor of variety uniformity over large areas, the more vulnerable such varieties are to losses from epidemics. The increased risks presented by genetic selection and the increased cultivation of only a few selected cultivars are easily perceived. Chapters 1 and 2 of this reports focus on crop vulnerability, because it is a broadly recognized problem. The issue of genetic vulnerability, however, is only one of several important problems affecting the management of global genetic resources.
