How can human activity can affect the carbon cycle.

Biology
2 answers:
Gemiola [76]3 years ago

Answer:

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

Answer:

Human activity can affect the amount of carbon in the atmosphere. When fossil fuels like oil, coal, and natural gas are burned, carbon dioxide is released into the atmosphere as waste. The clearcutting of forests for lumber and fuel also increases levels of carbon dioxide in the atmosphere because the trees can no longer remove carbon dioxide from the atmosphere for photosynthesis. If trees are burned in order to be cleared, the burning processes release even more carbon dioxide into the air.

:) please help!!! Briefly describe the traits seen in each genotype:
kolezko [41]
<h2>Answer 1 with Explanation</h2>

Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.

<h2>Answer 2 with Explanation</h2>

Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.

<h2>Answer 3 with Explanation</h2>

Homozygous recessive is described as an organism that carries two copies of the same recessive allele in the living organisms while they are in process of growth. A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).
