<em>A pesticide is a substance used to kill feral animals, insects, fungi or plants. There are thousands of different pesticides in use today. Pesticides are used in houses, shops, offices, sheds, gardens, farms, gas stations and other places.  Most of the pesticides used today are chemicals which have been developed in a laboratory by scientists and produced in factories. Some pesticides are very hazardous, they can be harmful to humans and other living things.  They can contaminate land, the air, food crops, water ways and seriously harm or kill native animals, pets and domestic animals. To the user, pesticides can also cause great harm and sometimes death to a person or other living things nearby.</em>

<em>Pesticides come in three different forms: </em>

<em>solids, which come in powder form (like flour), or in crystal or granular form (like sugar) </em>

<em>liquids, which look like milky water </em>

<em>aerosols, which are sprayed out in a fine mist</em>

<em>Hope this helps, sorry if not tho</em>

According to the article, why might Indians rationally choose not to eat cow even during times of starvation?
ludmilkaskok [199]

Answer:

Many Indians believe in Hinduism, which preaches that cows are sacred. They might choose not to eat cow even during times of starvation because they are afraid of the consequences that come in the afterlife. Because cows are sacred, Indians believe that eating them might incur a net negative benefit when considering the afterlife.

Explanation:

No article was provided and I don't particularly know much about the subject so this is my best guess. Please adapt this answer accordingly.

You are conducting an experiment to determine what concentration of disinfectant is most effective in killing bacteria. In this
butalik [34]

Answer:

C. Independent variable

Explanation:

The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable.

According to this question, an experiment is conducted to determine what concentration of disinfectant is most effective in killing bacteria. The independent variable is the CONCENTRATION OF DISINFECTANT because it is the variable being changed or manipulated.

Most metamorphic processes take place
natka813 [3]

Most metamorphic processes take place B. a few kilometers below Earth’s surface.

<h3>Further explanation </h3>

Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs  locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.

There are other ways that metamorphic rocks can form,  Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.

Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

Which organelles are found in a plant cell? Check all that apply. Endoplasmic reticulum centrioles cell wall vacuoles lysosomes
Shalnov [3]

Answer: Endoplasmic reticulum, cell wall, vacuoles, lysosomes, mitochondria, chloroplasts and cell membrane.    

Explanation: Following are the organelles found in plant cells.

Endoplasmic reticulum is the membrane bound organelle found in both plants and animals cells. The endoplasmic reticulum forms a network of canals it helps in transport of material in and out of the cell.

Cell wall is a rigid structural layer which forms an envelope around a cell. It is a rigid structural layer which is composed of cellulose. It provides protection to the cell and exhibit pores which facilitates the transfer of materials to pass to and from the cell membrane.

Cell membrane is a layer that surrounds the cell and separate it from the external environment. It is a selectively permeable structure which controls the material which is going in and out of the cell.

Vacuoles are membrane bound fluid filled organelles which store materials which are not required by the cells and helps in the waste disposal. They store materials like water, food, sugars, minerals and other waste products.

Chloroplasts are the organelles specifically found in the plant leaves. They have special pigment called as chlorophyll that traps the light energy from sun to conduct photosynthesis.

Mitochondria are tube like organelles these are the called as the powerhouse of the cell. Their function is in cellular respiration. They break the sugar molecules to produce ATP as a source of energy.

Lysosomes are the small sac like structures they exhibit a single membrane which contains strong enzymes which are capable of digesting cellular wastes. They also called as suicidal bags.

Centriole is an organelle which is not found in the plant cell. It is only found in the animal cells, their is a pair of centriole,  which are minute cylindrical organelles near the nucleus. These helps in the development of spindle fibers during cellular division.
