The Old field succession is a man-made secondary succession that occurs when a farmer stops cultivating their field for a lengthy period of time.
The definition of old fields, which has been a topic of discussion among modern ecologists for some time, is that they are an intermediate stage in the natural succession of an ecosystem moving towards its climax community. Many times, old field sites are marginal lands with poor soil quality that are unfit for pasture or farming.
The terms "grass and forbs stage," "shrub and sapling stage," "pole stage," and "mature forest" are frequently used by foresters to describe these stages. Forest succession is the process by which plant communities develop in a regular, predictable manner.
When a farmer gives up on a farm, the abandoned land quickly becomes overgrown with weeds and grass.

Answer:
There are two alleles for freckles.
Explanation:
<span>In comparison, mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells. Meiosis on the other hand is responsible for the cell division of the gametes, spermatogenesis (sperm cells) and oogenesis (egg cells), such haploid cells. Take for instance your integumentary system, layer of the skin in which your stratum basale always produces new epithelial cells (via mitosis) to take over until the outer layer, called stratum corneum (a continous replaced dead cells in this layer). </span>
Okay so, the mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. The outer membrane covers the organelle and contains it like a skin. The inner membrane folds over many times and creates layered structures called cristae. The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.
Hope that helps (:
<span>Gregor Mendel used peas to conduct his experiments in genetics. He showed how different alleles gathered from each of the parents, when combined, would reemerge as various characteristics in the offspring.</span>
