They can harm animals and humans. What ever digests the crops that pesticides are used on can get sick and diseased. Pesticides are dangerous for humans and animals and can kill.

Answer:

Pesticides are chemical or biological agents that are able to restrict the growth of pests in a agricultural field. These pesticides prevents the growth of insects or pests whose life cycle is mainly dependent on plants and those which are dependent for food requirement on plants. The pesticides making crop pest resistance can be harmful to animals and humans as these are toxic in nature. These pesticides can contaminate the air, water and soil in the regions where they are applied and causes respiratory, cardiac and water borne diseases in humans. These pesticides being toxic remains undigested and circulated in a food chain can be responsible for biomagnification. Biomagnification affects the growth and abundance of species in all trophic levels of the food chain but the highest trophic level is most affected because of accumulation of pesticides in the organisms reaches at higher concentration, responsible for mortality.

The discontinuous aspect of replication of DNA in vivo is caused by ________.
pychu [463]

Answer:

The 5' and 3' polarity restriction

Explanation:

Discontinuous replication is when synthesis of new DNA molecule takes place as a series of short fragments that will subsequently be joined together.

These fragments are called the Okazaki fragments.

DNA synthesis takes place from 3' to 5' end. However due to 5' and 3' polarity. The replication has to be discontinuous due to the synthesis happening backwards and okazaki fragments being formed.

Match the description on the right with the force on the left.
Marat540 [252]

Magnetic force - B.

Electrical force - A.

Gravitational force - D.

Contact force - C.

<h3><u>Explanation:</u></h3>

When a charge moves about its path, it produces a magnetic force around it. This magnetic field is perpendicular to the axis of movement of the charge and is directly proportional to the amount of charge, speed of the charge, and inversely proportional to distance between the charge and the point of measurement. Michael Faraday discovered this phenomenon.

Electrical force of attraction or repulsion is seen between the two charged bodies, or one charged body and one uncharged body which can induce charge to the uncharged body. The attraction or repulsion between the charged bodies are seen if the bodies are close enough, and this is called electrical force.

The gravitational force is also a non contact force that is seen between two bodies which is always attractive in nature and is seen between any two bodies.

A contact force like friction is a type of force that takes place only when two bodies are in contact with each other.

What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2
rusak2 [61]

Answer:

The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

Explanation:

The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.

The process of <u>cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions</u> where, from a glucose molecule, energy is obtained in the form of ATP molecules.

Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:

                                 <em>C₆H₁₂O₆  +  6O₂ →  6H₂O  +  6CO₂</em>

This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.

For the other options it is important to mention that:

  • <em><u>C₆H₁₂O₆</u></em><em> is the substrate from which cellular respiration takes place. </em>
  • <em><u>ATP </u></em><em>is the final product of cellular respiration, translated into energy to be used by the cell.</em>
