Explanation:
Homologous chromosomes are two pieces of DNA within a diploid organism which carry the same genes, one from each parental source.
In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes. So, our cells carry 46 total chromosomes, in two copies. However, each homologous chromosome can provide a different version of each gene. Two versions of each gene create more variety, lower the detrimental effects of negative mutations, and generally stabilize a population.

This change often meant a smaller fish catch but more rainfall inland that translated to more abundant crop harvest .

Hello! The answer is cell
<span>The juxtaglomerular apparatus is a structure (formed by the distal convoluted tubule and the glomerular afferent arteriole) with the function in the regulation of blood pressure and the filtration rate of the glomerulus. Its primary components are:
</span> <span><span>· </span>the macula densa- specialized epithelial cells in the distal convoluted tubule (detect Na concentration),
</span> <span><span>· </span>juxtaglomerular cells- formed from the smooth muscle cells of the afferent arteriole (secrete renin),</span>
<span><span>· </span>extraglomerular mesangial cells (lacis cells)-unknown function.</span> <span> </span>
