Answer:
Economic Benefits of Land Conservation
Economic Benefits of Parks
Economic Benefits of Trails
Economic Benefits of Smart Growth and Costs of Sprawl
Explanation:
Maintaining biodiversity is essential for organic waste disposal, soil formation, biological nitrogen fixation, crop and livestock genetics, biological pest control, plant pollination, and pharmaceuticals. Plants and microbes help to degrade chemical pollutants and organic wastes and cycle nutrients through the ecosystem. For example:
Pollinators, including bees and butterflies, provide significant environmental and economic benefits to agricultural and natural ecosystems, including adding diversity and productivity to food crops. As many as one-third of the world’s food production relies directly or indirectly on insect pollination. About 130 of the crops gown in the United States are insect pollinated. Habitat fragmentation and loss adversely affects pollinator food sources, nesting sites, and mating sites, causing precipitous declines in the populations of wild pollinators.
Answer:
a. the RNA polymerase undergoes abortive initiation prior to promoter clearance
Explanation:
In eukaryotes the 3' end of the mRNA is polyadenylated to protect the mRNA from degradation.
In eukaryotes, a modified guanine cap is added to the 5' end of the mRNAd to protects the transcript from being broken down.
Most bacterial RNA transcripts do not undergo splicing.
The nucleosome is the basic unit of chromatin repeat in eukaryotes.
It does in fact that's really what natural selection is all about it uses the characteristics that would better help the organism survive therefore making the species thrive

is a chromosomal condition that is associated with intellectual
disability, a characteristic facial appearance, and weak muscle tone
(hypotonia) in infancy. All affected individuals experience cognitive
delays, but the intellectual disability is usually mild to moderate.</span>
