Answer:
Clean Air Act
Explanation:
The Clean Air Act set guidelines on the amount of air pollution considered acceptable.
The Clean Air Act is a federal environmental law of the United States that was created to control air pollution in the country. The Clean Air Act is regulated by EPA (the U.S. Environmental Protection Agency), along with state and local governments. The Clean Air Act set guidelines such as the emission standards (commonly called maximum achievable control technology) which require the maximum level of reduction in release of hazardous air pollutants in the environment.
The given question says a cross is performed between two homozygous recessive individual, both having genotype ttyy.
In any case, the gametes produced by these plants would be recessive for the trait and the cross between these individual would always give rise to a homozygous recessive progeny.
Hence, in any case, the progeny would be homozygous for allele t, and allele y.
So, the probability of offspring having homozygous for gene t and homozygous for gene y would be 100% or 1.
Your answer
Biogeography is the scientific study of the distribution of species and ecosystems throughout geographical space and over periods. It combines information from biology, geology, and climate science to understand where life exists, where it did in the past, and where it might in the future.
Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. It examines patterns of species distribution on Earth and their historical changes. For instance, if we take the example of kangaroos being native to Australia, it's the field of biogeography that explains why such a condition came to be. By merging information from different scientific fields such as geology, biology, and climate science, biogeography can tell us where life exists now, where it existed in the past, and where it might exist in the future. Biogeography is broadly divided into two types: Historical Biogeography (which focuses on long-term, evolutionary timescales) and Ecological Biogeography (which focuses on shorter, ecological timescales). It's a key element in many biological and geographical studies, as understanding the spatial distribution of species can help in conservation planning and can provide insight into the processes of evolution & adaptation.
