"A Synapse" is the <span>name for a quick, unlearned, and automatic response. the other options given in this question can be neglected. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that has come to your help.</span>
I think the correct answer would be the first option. Chemical weathering would be most effective in a warm, humid climate. It is a type of erosion which is caused by chemical reaction that happens naturally in the environment. It is usually caused from the reaction of the minerals found in rocks with the rain water. These reactions happen when the rain water contains acidic components. Also, its occurrence would be more fast in places where there is high temperature or in warm regions specifically for hydrolysis and oxidation reactions. For the reactions to happen, the presence of water is very important so it most likely in humid places.
The initial cell division of meiosis , known as meiosis I, divides the chromosomes into two cells. After this division, each cell receives a ploidy number of 2N.
<h3>What is the meiotic ploidy?</h3>
After meiosis II, there is no decrease in ploidy since both parent and daughter cells only have one copy of each meiosis. Each cell after mitosis has a chromatid for every homologous chromosome. Thus, each cell has enough DNA to make two copies of each chromosome.
Reductional division also occurs during the first meiotic stage, when a diploid parent cell divides into haploid daughter cells, resulting in a shift in ploidy. Meiosis II does not include a change in ploidy because it is an equational division.

The tip of the pyramid ends in a cuplike structure called the papilla.
Papilla projects into a calyx. Its surface has a sievelike appearance since it is where urine droplets pass through its small openings. Each opening represents a tubule known as the Bellini duct through which collecting tubules within the pyramid converge or meet. The muscle fibers lead from the calyx to the papilla. As the muscle fibers originating from calyx contract, urine flows through the Bellini ducts into the calyx. The urine flows through the renal pelvis and the ureter and it eventually drains down into the bladder.
