Endocrine disruptors are commonly found in pesticides, plastics, and consumer products, and industrial by-products. Thus, the correct option for this question is D, i.e. all of the above.
What do you mean by Endocrine disruptors?Endocrine disruptors may be defined as a type of extrinsic substance or mixture that significantly changes the function of the endocrine system and subsequently stimulates adverse health effects in an intact organism, its offspring, or populations.
According to the context of this question, pesticides like DDT, Atrazine, etc. plastics, and food storage materials like bisphenol A (BPA), Phthalates, Phenol, etc., and industrial by-products Polychlorinated biphenyls (PCBs) and Dioxins causes the significant and effective disruptions of the endocrine system.
Endocrine disruptors are found in numerous everyday products, including plastic bottles and containers, liners of metal food cans, detergents, flame reductions, food, and pesticides.
Therefore, endocrine disruptors are commonly found in pesticides, plastics, and consumer products, and industrial by-products. Thus, the correct option for this question is D, i.e. all of the above.

Answer:
the light comes from the sun
Explanation:
the light from the sun reflects on the moon and the moon gets its light.
The moon is always half-lit by the light that comes from the sun except during the lunar eclipse. The light source for the moon is the sun.
What are the phases of the moon?The lunar phase or Moon phase can be described as the shape of the Moon's directly sunlit portion, which can be demonstrated quantitatively using areas or angles, or qualitatively utilizing the terminology of the four major phases: new moon, first quarter, full moon, last quarter.
The lunar phases gradually change over a month as the Moon's orbital positions around Earth and the position of the Earth around the Sun shift. The visible side of the Moon is sunlit, according to the position of the Moon in its orbit.
Thus, this face's sunlit part of the moon can vary from 0% to 100%. Each of the 4 major lunar phases is approximately 7.4 days, with +/− 19 hours in variation due to the elliptical shape of the orbit of the Moon.

A scientist observes hot water erupting from a vent in the Earth.What most likely caused the water to rise and erupt from the vent? someone pls answer i if u answer u get 57 points
Answer/Explanation:
A geyser is hot water erupting from a vent in the earth. Geysers are somewhat rare and occur in certain parts of the earth. Underneath, there are hidden chambers that provide constant flows of water. Sometimes when the tectonic plate of the earth move, it leaves gaps in between the hot earth's inner core and the ground. The magma inside is able to heat up the water from the earth. Since hot particle tend to rise, the water explodes out of the vent with such power from the heat.

Answer:
c- subduction zones
Explanation:
A mental plum is generally found within the mantel and is a mechanism of convection, the plume is often invoked as the causes of volcanic hotspots. Such can be seen on Iceland and Hawaii islands. They represent a large volume of volcanism near the plate boundary. Mantle plumes are believed to be a source of molten magma from the earth.As the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the
As the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.
What is effective nuclear charge?Effective nuclear charge of an atom is the attraction force of positive charge of protons present inside the nucleus acts as an valence electrons.
The effective nuclear charge is alway slower than the total number of protons of the nucleus because of shielding effect. Where Z is the atomic number and S is the number of shielding electrons.
Therefore, the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.
