People spray pesticides on crops to kill insects that eat and destroy the crops. However, these insects are becoming resistant to the pesticides. Explain how this could happen.

Answers

The same way bacteria becomes resistant to antibiotics.

Mutations in their DNA.

When an organism or insect develops a mechanism for the removal of the pesticide compound is known as pesticide resistance.

What is pesticide resistance?

The organism or insects develop mechanisms such as the alternation of the binding site of the compound present in the pesticide leading to the development of resistance against the used pesticides. The development of resistance against the pesticide is a slow process, it takes time. The usage of pesticides becomes a failure if organisms develop resistance.

The frequent use of pesticide and insecticides cause changes in the genetic material of the organisms. They help in the development of enzymes and changes in the binding sites. These changes are passed on to the next generation of the organism, which makes the entire population resistant to the particular pesticide and insecticide.

The use of the chemicals should be monitored. Only use when required with rotation.

Which factor can decrease the rate of a chemical reaction?
Olow activation energy
O high pressure
O low temperature
O high concentration of enzyme

Answers

Answer:

Low temperature

Explanation:

because.

Have a great day!!!

The factor that can decrease the rate of a chemical reaction is a low temperature.

What is chemical reaction?

A chemical reaction is the chemical transformation of one set of chemical substances into another.

A low temperature is one factor that can slow down a chemical reaction. A chemical reaction is defined as a process that transforms one set of chemical substances into another.

The rate of a chemical reaction is a measure of how quickly the reaction takes place.

A low temperature can slow down a chemical reaction by lowering the kinetic energy of the reacting molecules.

This means the molecules move slower and are less likely to collide with enough energy to break bonds and form new ones. As a result, the reaction rate slows down.

Thus, the answer is low temperature.

The amusement park will be located in a hot climate. The engineers want to select a material for the giant slide that will prevent the surface from getting too hot. Based on the specific heat values, what material would be the best choice? A.Plastic, because it takes more energy to raise its temperature B.Iron, because it takes more energy to raise its temperature C.Plastic, because it takes less energy to raise its temperature D.Iron, because it less energy to raise its temperature

Answers

Answer:

A

Explanation:

The correct answer would be plastic because it takes more energy to raise its temperature.

The specific heat capacity of a substance is the amount of heat required to raise the temperature of the substance by one degree. The more the specific heat capacity of a substance, the more the heat required to raise its temperature.

The specific heat capacity of plastics is generally more than that of metals. Hence, metals will get heated faster than plastics under the same condition. More energy would be needed to raise the temperature of plastics when compared to metals.

the correct option is A.

Starch contains two polymers of glucose, they are amylose and amylopectin. Amylose differs from amylopectin in that

Answers

Answer:

Amylose is a straight chain whereas amylopectin is a branched chain polymer.

Explanation:

Amylose differs from amylopectin because amylose is a straight chain while on the other hand, amylopectin is a branched chain polymer. Branched chain polymers refers to main chain with smaller chains as branches of main chain while straight chain polymer has only main chain and no branches of main chain. Starch comprise of about 10-20% amylose and 80-90% amylopectin. Starch is considered as the main storage of energy for green plants.

Put the following in order from most thermal energy to least thermal energy. ​

Answers

from hottest to coldest:

- the turkey

- the tea

- the beach

- the, what is it, an iceberg or ocean?

- the ice cube

refer to the other question I answered by you. 0 degrees Celsius would be frozen, 100 would be boiling hot. Since -2 is the lowest, that would be the coldest/ least amount of thermal energy. 60 degrees Celsius is the highest, so it has the most thermal energy. Again, thermal energy is just heat energy, so you just need to figure out which is hottest.

what are the 7 factors of classification of living things

Answers

1 Nutrition

Living things take in materials from their surroundings that they

use for growth or to provide energy. Nutrition is the process by

which organisms obtain energy and raw materials from nutrients

such as proteins, carbohydrates and fats.

2 Respiration

Respiration is the release of energy from food substances in all

living cells. Living things break down food within their cells to

release energy for carrying out the following processes.

3 Movement

All living things move. It is very obvious that a leopard moves but

what about the thorn tree it sits in? Plants too move in various

different ways. The movement may be so slow that it is very

difficult to see.

4 Excretion

All living things excrete. As a result of the many chemical

reactions occurring in cells, they have to get rid of waste products

which might poison the cells. Excretion is defined as the removal of

toxic materials, the waste products of metabolism and substances

in excess from the body of an organism.

5 Growth

Growth is seen in all living things. It involves using food to

produce new cells. The permanent increase in cell number and size

is called growth.

6 Reproduction

All living organisms have the ability to produce offspring.

7 Sensitivity

All living things are able to sense and respond to stimuli around

them such as light, temperature, water, gravity and chemical

substances.

Vertebrates are complex animals, but they still share some characteristics with invertebrates. Mia volunteers at her city's aquarium for the summer. She likes observing the invertebrates. Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms?

Answers

Answer: Their body structure becomes increasingly more complex.

Explanation:

In the classification of living things, all animals belongs to Kingdom Animalia. This is contains two main groups namely:

--> invertebrates and

--> Vertebrates.

The vertebrates are complex animals which are characterized with the presence of a backbone.

The invertebrates are less complex animals with no backbone. The phyla that exists in this group includes: porifera, coelenterata, platyhelminthes, nematodes,annelida, mollusca, arthropoda,echinodermata and many among others.

Their body structure becomes increasingly more complex from the phylum porifera to the phylum echinodermata. The Sponges are simple aquatic invertebrates that have ASYMMETRICAL BODIES (this makes them to lack specialised tissues that could prevent them from moving about). While the echinodermata have RADIALLY SYMMETRICAL body with body parts arranged around a central mouth and anus. They have a unique system of water canals for transport inside the body and numerous tube feet moving about.

If you are neither relaxing or contracting a specific muscle, what is happening to the amount of ATP that is available in that muscle cell?

A. It is staying the same or increasing.
B. It is decreasing rapidly.

Answers

Answer:

A. It is staying the same or increasing.

Explanation:

The body tissues and cells require energy in the form of ATP to work, grow and move. It is produced from cellular processes like ETC, cellular respiration and other metabolic processes.

The amount of ATP in the cell:

Option A. It stays the same or increases.

The function of ATP can be explained as:

Muscle contraction and relaxation requires a certain amount of energy in the form of ATP. The insufficient amount will not be able to support the relaxation or the contraction of the muscle tissues.

In the condition where there is no contraction or relaxation the amount of energy will be the same or increased as it is not used in the process and remains constant.

Therefore, it remains the same or increases.

Yeah it's possible. Even though both parents have round jaws... that may be the result of a dominant trait overpowering the recessive trait. As long as both parents have the recessive gene (in other words they're heterozygous traits) then there is a possibility for a child to be born with a square jaw.
