A) If red hair were a recessive trait, it could be inherited in two ways: 1) from heterozygous parents who both carry the red hair allele (the chances of having a child with red hair would be 25%), or 2) from red haired parents who are both homozygous (100% chances of red haired offspring).
B) If red hair were a dominant trait, it could be inherited only if at least one of the parents had red hair. There's 3 variables: 1) If both parents were heterozygous, they would have a 75% chances of having red haired children; 2) if one parent were heterozygous and the other were homozygous dominant, all of their offspring would have red hair; and 3) all children would be red haired if both parent were homozygous, one dominant and the other recessive.
This exercise is an example of Mendelian inheritance which states that the genes inherited from parents are separated into gametes in equal frequency. Each parent "donate" an allele to their offspring; this allele could be physically expressed or not depending on it being dominant or recessive (this means: silent) and if the parents being homozygous or heterozygous. Heterozygous individuals have two different alleles (one dominant and one recessive), while homozygous can have either 2 dominant alleles or 2 recessive ones.
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil,such as a lava flow or area left from retreated glacier,is deposited <span />

Explanation:
2: most energy plants in the U.S. use coal as its fuel
1. The process of photosynthesis and respiration are often found in the same organisms, so they are directly connected. In this case, we have significant increase in the levels of carbon dioxide, and carbon dioxide is a crucial element in the process of photosynthesis. The more carbon dioxide there is, the more organisms can perform photosynthesis. Once the organisms are able to perform photosynthesis, the next step is that they need to use the created sugars from it to convert them into energy. The sugars combined with oxygen produce the energy for growth, thus we can say in this case that the increase of carbon dioxide has increased the amount of photosynthesis, which increased the amount of respiration.
2. The steady increase of the carbon dioxide will result in higher temperatures because it is a greenhouse gas that has the ability to trap the heat. This means that organisms that are better suited for warmer climates will thrive, while the others will either have to adapt, or go extinct. Also, the higher amount of carbon dioxide and warmer weather conditions will result in longer growing season, thus more producers will be able to thrive as the carbon dioxide is crucial for them to perform photosynthesis.
3. If the population of cyanobacteria starts to increase dramatically, then the area will experience multiple changes. The cyanobacteria will extract large amounts of carbon dioxide from the atmosphere, thus lowering its levels, while in the same time releasing large amounts of oxygen in the atmosphere. The graph will start to look much different as the carbon dioxide curve will be heading downward, and if the trend continues it will go even lower than its starting point of measurement in 1958, resulting in colder weather conditions and changes in the environment.
