What factors go into calculating an ecological footprint

zzz [600]

<h2>Ecological Footprint</h2>

Explanation:

The Ecological Footprint of an individual is determined by including the entirety of individuals' requests that vie for organically gainful space, for example, cropland to develop potatoes or cotton, or backwoods to create timber or to sequester carbon dioxide outflows.
The national normal or per capita Ecological Footprint of utilization is equivalent to a nation's Ecological Footprint of utilization isolated by its populace.
As indicated by the Global Footprint Network, the Ecological Footprint for the normal American is 8.6 gha, more than twofold Brazil's normal of 3.1 gha and Mexico's normal of 2.6 gha. Check The month to month service bills.

Increase your kilowatt hours by 1.85. For instance, 67 hrs X 1.85 = 123.95 lbs of CO2.
Increase your flammable gas use (therms) by 13.466. For instance, 19 therms X 13.466 = 255.854 lbs of CO2.
Increase gallons or propane utilized by 13.
Increase gallons of fuel utilized by 22.

Cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell? if a cell at meta

kumpel [21]

Answer:

The correct answer would be 10.

The cell cycle can be divided into four phases namely gap 1 (G₁) phase , synthesis (S) phase, gap 2 (G₂) phase, and mitosis (M) phase.

DNA (deoxyribonuceic acid) content is only replicated and doubled in the S phase. However, the chromosome number remains the same. It can be explained as the number of chromosomes remains the same (2n) but number of chromatids doubles (4n) after S phase.

The number of chromatids restores to 2n in daughter cells after completion of mitosis.

Hence, if number of chromatids in metaphase was 20 i.e. 4n then the number of chromosomes (2n) would be 10.

Hence, 10 chromosomes or 5 pairs of chromosome would be present in the cell during its G₁ phase.

Genetic mutations pass to offspring in gametes because gametes A) are not germ cells. B) make up all internal organs. C) do not

Anni [7]

Because gametes (sex cells) are the only cells that pass along genetic information. Somatic cells are the cells that have already differentiated into various organs or tissues. They can't pass on a mutation to offspring because they're not involved in creating it.

The answer is D. They fuse during sexual reproduction

How does natural selection favor an individual that can detect deceitful communicators? see section 50.5 ( page 1062) ?

Gnesinka [82]

This is comparable to the impression of the 'sneaky' males in the side-blotched lizard. Natural section favor an individual by the detector or sensor will sustain less cost and increase an advantage and gain over others incapable to distinguish the deceitfulness.
