The term that describes both alleles being expressed within an offspring is known as Codominance dominance. Thus, the correct answer is option (C).

In genetics, codominance refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to produce different traits in an individual. That is, instead of one trait predominating over the other, both traits appear, as in a plant or animal with multiple pigment colors.

The MN blood group system of humans is an example of codominance. Two alleles, M and N, govern MN blood type. The M antigen is a surface molecule seen on red blood cells in people who are homozygous for the M allele. Those who are homozygous for the N allele also have the N antigen on their red blood cells.

Therefore, Codominance dominance is the correct answer.

Answer:

busy port and trade connections

Explanation:

The first set of municipal legislators were elected in 1808 and then nine years later, in 1817, the first steamboat known as Zebulon pike, arrived St. Louis. It took the steamboat 30days to get to St. Louis from Louisville, Kentucky and that improved connections with New Orleans and eastern markets.

By 1821, Missouri was admitted as a state and a year later, St. Louis was incorporated as a city in 1822 and continued to evolve rapidly due to the busy port and trade connections.

All these crops needs Nitrogen, phosphorus and potassium in large amount for better growth and productivity. These nutrients such as Nitrogen, phosphorus and potassium needed by the plant at different amounts due to the crop physiology.

Answer:

Human activity, including irrigation practices, hydroelectric dams, and intense agricultural use, have led to desertification in the Sahel region. In addition, global warming has added to the problem. Over time, the soil becomes overused and sterile. As that dry and arid soil moves, it begins to encroach on local bodies of water. Lake Chad, as a result, has shrunk in size. Just 40 years ago, this lake contained 15,000 square miles of water. It now contains just over 500 square miles of water.

The locals of this region depend heavily on both fertile soil and healthy bodies of water for survival. Desertification can greatly endanger their way of life. For example, famers cannot produce the necessary crops, and fishers cannot rely on as much seafood. The article mentions that fishers who used to be able to fill hundreds of traps can now barely fill one. Desertification in the Sahel and its impact on Lake Chad will have a lasting effect and could possibly mean a different way of life for generations to come in the region.

Explanation:

The Sahel region's desertification is an issue as, without the roots of trees and other plants, the wind may easily sweep the dust away.

Due to these problems, water is now in short supply for local residents, animals, and plants. Farmers and herders are unable to continue living their traditional lifestyles without access to water and productive land.

The "Basin" of Lake Chad, which makes up over 8% of the continent, is divided among seven nations: Algeria, Cameroon, Libya, Chad, Niger, and Nigeria. Due to overuse and the consequences of climate change, the water body has decreased by 90% since the 1960s.

As a result of desertification and climate change, which have reduced Lake Chad's surface area by 90% since 1960, the lake is gradually disappearing. The lake is located in the center of the humanitarian catastrophe brought on by the fight with the Boko Haram group's armed forces, making it dangerous to access what little is left.

The lake was formerly among the world's greatest bodies of water.
