Answer:

Inequalities in the exposure to environmental burdens and access to environmental benefits are an environmental justice concern for urban and regional environmental planning. Recent studies have assessed the exposure of different populations to a combination of environmental hazards through GIS-based Cumulative Environmental Impact Assessments (CEIA). The contribution of this study is the development of a CEIA, which incorporates the distance-based impact of transportation, the cumulative impact of environmental hazards, and access to environmental benefits for Santa Clara County (SCC), a highly diverse and rapidly developing region also known as ‘Silicon Valley’. Our results show that social vulnerability, cumulative environmental hazards, and environmental benefits exhibit distinct spatial patterns in SCC.

IgorLugansk [536]

Answer:

Number of nucleosomes in $2.9 * 10^9$ bp is equal to $1.47 * 10^7$

Explanation:

For wounding one nucleosome, total length of DNA required is equal to $146$ bp

The length of linker DNA in mammals is equal to $50$ bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

$= 146 + 50\\= 196$ bp

Thus, in $196$ bp length of DNA, the total number of nucleosomes is equal to $1$

Thus, number of nucleosomes in $2.9 * 10^9$ bp is equal to

$\frac{2.9* 10^9}{196} \\1.47 * 10^7$

By which process are fossil fuels formed?

Lilit [14]

They are formed by natural processes like anærobic decomposition. They contain energy from ancient photosynthesis. They can literally be around 650 million years old.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl

N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.
