A lot of carbon stored inside the Earth may soon re-enter the atmosphere, according to a new, global study on soil-based carbon. The massive release of carbon could be the equivalent of adding another fully industrialized country the size of the United States to the map over the coming decades.
Plants, animals, and microbes absorb much of the carbon dioxide released into the Earth's atmosphere by burning fossil fuels. As these plants and animals die, their carbon-based bodies become part of the soil, storing the equivalent of millions of tons of greenhouse gases in the dirt. As atmospheric carbon dioxide is a primary driver of climate change, some have pointed to this soil absorption as a helpful carbon sink, somewhat alleviating the human-caused warming of the planet. But as surface temperatures continue to rise, a lot of the carbon stored in the soil may be set to re-enter the atmosphere in a big way.
.B) decomposition of organic matter
That question is confusing. Cells obviously take from its parent cells, which means that DNA is combined from both mom and dad in a unique way. That can cause the offspring to have either the mom's or dad's eyecolor. So the "different genes" part apply to that because for each feature of the offspring it is a complex combination of mom and dad. What I don't get is the different cells. there are these things called stem cells which are basically cells that can be anything in the body when there's a need for it. A stem cell can be a nerve cell or muscle cell for example. So i don't think it requires genes to be exact to form a cell. I hope you get what I'm trying to say
Answer:
The law of independent assortment states that the different genes get separated independently of each other and gets assorted into gametes to produce different combination of genes.
It was formulates by famous scientist G. Mendel based on his work on peas.
For example, in a traditional dihybrid cross of true breeding round and yellow seed plant with wrinkled and green seed plant, F2 generation show four different combinations of phenotype:
- round and yellow
- round and green
- wrinkled and yellow
- wrinkled and green
It shows that genes for round and yellow were independently inherited and genes for wrinkled and green were independently inherited. Else, new combinations could not be observed.
Homologous recombination is an event that takes place in prophase I during meiosis. The genetic material is exchanged between the non-sister chromtids of homologous chromosomes. It adds into the genetic variation within a population by producing more combination of genes in the gametes.
It does not violate the law of independent assortment as the genes were independently assorted. It only helps in producing more combinations of genes.
Answer:
There are many different organ systems that are involved in when we exercise. The three main ones are the respiratory system which is involved in breathing, the circulatory system which circulates blood flow throughout the body and lastly the muscular system, as you use muscles when you are moving.
