Answer:
The impact of pesticides on soil biota can be either positive or negative, depending on the type of pesticide used. Genetically modified organisms (GMOs) are generally designed in order to be more resistant to pesticides, thereby GMOs might have a higher impact on the soil biota (however, the evidence is not conclusive and case by case should be evaluated)
Explanation:
Traditional chemical pesticides are chemical substances used to control pests (e.g., insect pests affecting corn yield). Examples of traditional chemical pesticides include 2,4-Dichlorophenoxyacetic Acid, DDT, Atrazine, Chlordecone, etc. The impacts of these traditional pesticides on soil biota are variable according to the type of product used, the rate at which these products are applied, the target/non-target soil biota (e.g., bacteria, algae, fungi, protozoa, insects, nematodes). For example, it has been reported long-term contamination of DDT on soil microflora (i.e., microalgae and cyanobacteria), thereby these non-target species declined with increasing DDT use; however, direct effects on fungi populations were not observed. Genetically modified organisms (GMOs) are organisms whose DNA has been engineered by using molecular biology techniques. In crop improvement, GMO plants are designed to be more resistant to chemical pesticides and also to produce pesticides themselves, for example, Bt crops that produce a toxin from Bacillus thuringiensis (Bt) that can kill insect pests. GMO plants can also be designed to be more resistant to pesticides, thereby affecting soil biota at higher scale values. Nonetheless, it is important to highlight that like chemical pesticides, the effects of GMOs on soil biota are also variable depending on the type of GMO, which pesticide GMO is producing, target/non-target soil species, etc.
what are the reproductive systems of insects?
Hey! Your answer to this question..
What are the reproductive systems of insects?
Insects that’s is female can make eggs, receive and store sperm, manipulate sperm from different males. They can also lay eggs of course. Insects reproductive systems are made of a pair of ovaries, accessory glands, one or maybe even more spermathecae, and lastly ducts connecting these parts. The ducts and spermathecae are line with a cuticle.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in
compost bins, forming a dirt-like substance that's rich in nutrients. The next season, farmers use this
substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer
formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in
unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to
grow faster and taller than his artificial fertilizer. Explain independent and dependent variables
Answer:
Please find the explanation of independent and dependent variables below using the experiment in this question.
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment while the dependent variable is the variable being measured in the experiment.
According to this question, a biology student who has grown tomato plants for several years wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer, which he used previously.
In this case, the "natural compost" is the independent variable while the dependent variable is how tall and fast the tomato plant will grow. Hence, the tallness or fastness is the dependent variable.

In organisms other than plants, when and where is the most ATP produced?
in cytoplasm, during photosynthesis
in nuclei, during cellular respiration
in chloroplasts, during photosynthesis
in mitochondria, during cellular respiration
Answer:
D. In mitochondria, during cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
All living organisms such as plants and animals require energy to function properly (life activities). Thus, the organelle where energy from nutrients is released is generally referred to as mitochondria. Animals retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In organisms other than plants, the most ATP is produced in mitochondria, during cellular respiration.

-There is less land to use for habitat after the producers grow.
-More tertiary consumers will eat secondary consumers over producers.
0r
-There isn’t enough energy available to support more secondary consumers.
Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.
When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.
Biomass change from lower to higher trophic levels by decreasing.
The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.
There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.
It should be noted that global warming brings about the increase in the temperature around the world.
