Which is NOT one of the four fundamental forces in the universe?
Electromagnetism
Strong
Gravity
Mass
Answer:
Mass
Explanation:
From walking on the street, to launching a rocket into space, to sticking a magnet on your refrigerator, physical forces are acting all around us. But all the forces that we experience every day (and many that we don't realize we experience every day) can be whittled down to just four fundamental forces:
Gravity.
The weak force.
Electromagnetism.
The strong force.
These are called the four fundamental forces of nature, and they govern everything that happens in the universe.

¿de que manera el desarrollo cientifico y tecnologico repercute en la agricultura ecologica ,como parte de las condiciones para la propuesta de emprendimiento familiar?
Answer:
Los desarrollos científico-tecnológicos han impactado positivamente sobre los sistemas de agricultura ecológica y en última instancia también sobre la agricultura familiar
Explanation:
La agricultura ecológica refiere a los procedimientos de explotación agrícola basados en la utilización sustentable de los recursos de la tierra y los métodos de fertilización orgánica, respetando el ambiente natural y evitando el uso de compuestos químicos artificiales (como por ejemplo plaguicidas químicos) y de cultivos transgénicos. Por otra parte, la agricultura familiar refiere a un tipo de agricultura ecológica basado en la dirección y la administración familiar. La agricultura familiar es el sistema de agricultura predominante en regiones pobres de América Latina y el Caribe, representando aproximadamente el 80 % de la producción agrícola. De este modo, el desarrollo de métodos eficientes de agricultura/ecológica familiar resultan fundamentales para lograr la seguridad alimentaria en la región y también para mitigar los efectos negativos del cambio climático. En este contexto, diferentes avances científico-tecnológicos han impactado positivamente sobre el manejo, eficiencia y productividad de la agricultura familiar como sistema de cultivo no sólo sustentable sino también eficiente, entre los cuales se destacan el desarrollo de mini-invernaderos, variedades mejoradas obtenidas a través de técnicas de mejoramiento genético convencional (selección a campo), trampas artesanales para la captura de insectos plagas, etc. Diferentes tecnologías/metodologías como las anteriormente citadas han sido ajustadas y validadas a partir de procesos de experimentación participativa con el objetivo de estudiar cuales son las condiciones de la zona que mejor se adaptan al tipo de cultivo y de incrementar la productividad de sistemas de cultivos sustentables.

Answer:
This looks like an earthquake
Explanation:
There doesn’t seem to be very much water present in the image which would be the cause for the rest of them
Hope this helps
Answer:
Earthquake
Explanation:
First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.

Pesticide resistance is increasing, Farmers in the US tost 7% of their crops to pests in the 1940s, over the 1980s and 1990s, the loss
was 13%, despite more pesticides being used. It is estimated that 500-1000 pests have developed a resistance to pesticides. Consider
the diagram showing the evolution of pesticide resistance. Select ALL of the statements that do NOT accurately describe the
mechanisms of pesticide resistance shown in the graphic.
A)Insects that are sensitive to the pesticide all die out after the first
application, leaving only the resistant insects in the population,
B)When insects are exposed to the pesticide, some will develop a mutationmaking it resistant. Only these insects survive in the next generation
C)The first generation has an insect with a gene responsible for resistance toa pesticide. This allows it to survive the pesticide application and reproduce
D)The insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this
trait become more prominent in the population
E)As a population of insects is exposed to a pesticide, those susceptible to
the pesticide will die out of the population, leaving those with a resistance
to survive and reproduce, becoming more common in the population
The insect with the pesticide resistance gene reproduces, these insects are more likely to survive pesticide application hence insects with this trait become more prominent in the population
What is a pesticide?A pesticide refers to a chemical that is used to control the spread of pests in the farm.
The question is incomplete but I will help you the much I can. We know that organisms that have favorable traits live long enough to reproduce and pass on these favorable traits to the next generation. Therefore, the insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this trait become more prominent in the population

Why is the classification species not considered a group
Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups.
There are five kingdoms: • Animals • Plants • Fungus • Protist • Bacteria Scientists classify animals together because they have similar characteristics such as they eat other living things and have many cells. As you can see from the chart, kingdoms are divided into groups called phyla.
hope it helps ya mate.
hoping to have a brainliest.
The classification of species is not considered a group because each species is a separate type of organism. The correct option is D.
What are groups and species?Group is the level of taxonomy in which the organism is present, which has someone's character. Like in the insect group, all insects are present.
Species are the largest level of the taxonomy of the organism. Species are animals or plants or individuals that have the same characteristics and those that can mate with each other and form fertile offspring.
Groups contain numerous species. Like in insects, the insects contain numerous insects that are very different from each other. Like, bees and beetles are very different from each other.
Thus, the correct option is D. Each species is a separate type of organism.
