Answer:

Sulfur; nitrogen.

Explanation:

Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.

This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.

Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.

Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.

1)How do populations of invasive species continue to grow, and disrupt ecosystems?
s344n2d4d5 [400]

Answer:

Due to absence of predators.

Explanation:

The populations of invasive species grow rapidly because of the absence of predators that can control its population as as result, it disrupt the whole ecosystem. Change of climatic conditions of the area where they live causes them to migrate from its original place to a new region where the invasive species have no predators to control its population but mostly humans are responsible for the introduction of invasive species. In most cases, the introduction of invasive species happen due to human activities.

Phases of meiosis on the lines provided, identify the stage of meiosis i or meiosis ii in which the event described occurs. 9. e
Natalka [10]
Meiosis I
Prophase I - homologous chromosomes form a tetrad, where they begin cross-over through the process of synapses.
Metaphase - homologous chromosomes then align along the metaphase plate.
Anaphase I - spindles then separate the homologous chromoses, pulling them to opposite poles of the cell
Telephase I - the cell creates a cleavage burrow inwhich the cell divides into two new cells with 46 chromosomes in the process of cytokinesis

Meiosis II
The same as mitosis
Prophase II - Nuclear envelope disintegrates, Sister chromatids migrate towards the metaphase plate.
Metaphase II - Sister chromatids align along the plate by their centromere.
Anaphase II- spindles pull the chromatin to opposites poles
Telephase II- cleavage burrow forms and cells seperate through cytokinesis

end result
4 haploid gametes are formed
