Answer:
C
Explanation:
People use herbicides to keep bugs and other things off of plants so when it rains, that can wash off into the ground and thus into our food, our water sources, etc.
The pollutants are most likely released into bodies of water by agriculture are herbicides and pesticides.
How do pesticides work?
Pesticides act in the control and proliferation of pests, weeds and in the fight against possible diseases associated with the cultivation of certain products. They are composed of substances capable of acting on the biological activity of living beings that are in agricultural crops.
The food contamination, river pollution, soil erosion and desertification, intoxication and death of farmers and extinction of animal species, are some of the most serious consequences of industrial chemical agriculture and the indiscriminate use of pesticides, widely stimulated in the last 25 years.

How are sediment rocks made
Explanation:
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.

Genetic Engineering has led to genetically modified plants that resist insects, pests and bacterial and fungal infections. Which outcome would most likely be a reason why some scientists recommend caution in planting genetically modified plants?
1Points
A
improved agricultural yield and profit
B
increased genetic variation and diversity
C
reduced pesticide and herbicide use
D
unplanned ecosystem interactions
Answer:
D. a red allele present on at least one of two homologous chromosomes;
D. unplanned ecosystem interactions
Explanation:
A dominant allele or trait would always mask the expression of a recessive trait when both are present in a pair. The only way a recessive trait can express itself is when it is in a homozygous state. Since red color is dominant over white color in the beetle species, the genotype of any red color species would have a red alelle present on at least one of two homologous chromosomes. For example, if red allele is represented by R and white allele is r, the genotype of a red nettle species would be RR or Rr.
In the second question concerning the most reason for concern that some scientists recommends caution be taken regarding genetically modified plants is that in the process of introducing new genes into a population, unforseen and unplanned disruption of the ecosystem may occur as a result of interaction with the ecosystem that these process and it's product may present.

What would most likely happen if an ecosystem that regularly recieved sunlight no longer received sunlight?
all living organisms would eventually die
the number of herbivores would increase
all organisms would adapt
the number of plants would increase
Answer:
All living organisms would eventually die.
Explanation:
If an ecosystem that regularly received sunlight no longer receives sunlight, then ALL living organisms would eventually DIE.
Sunlight is the primary source of energy for many ecosystems in which primary producers (e.g., plants and algae) generate energy and biomass through photosynthesis.Photosynthesis is a series of metabolic reactions by which primary producers use the energy from the sun and carbon dioxide to produce simple carbohydrates and oxygen.The primary producers sustain all life in an ecosystem by providing biomass and energy to primary consumers (e.g., herbivores).In conclusion, if an ecosystem that regularly received sunlight no longer receives sunlight, then ALL living organisms would eventually DIE.

I NEED YOUR HELP!!! Explain the changes that occur as a tadpole becomes an adult frog or toad.
Answer:
Sample Response: Tadpoles have fins, gills, and a two-chambered heart, similar to fish. As tadpoles grow up, they develop legs, lungs, and a three-chambered heart. The tail is reduced in size and lost completely as they prepare to leave the water.
Explanation:
During metamorphosis, a tadpole's gills and tail disappear, hind legs develop first, followed by front legs, and lungs replace gills, resulting in an adult frog or toad.
What is Metamorphosis?Metamorphosis is a biological process that describes the transformation of an animal from one developmental stage to another, such as a tadpole becoming a frog or a caterpillar becoming a butterfly. In frogs, metamorphosis involves a series of changes that occur as the tadpole develops into an adult.
During this process, the tadpole's gills and tail disappear, hind legs develop first, followed by front legs, and lungs replace gills. The skin also thickens and changes, and the digestive system adapts to a new diet. Overall, metamorphosis is a critical part of the life cycle of many animals and allows them to adapt to new environments and ecological niches.

There are mainly two types of genetic drift and these are population bottlenecks as well as the second one is the founder effect.
The term hormones means that they are the chemical messengers of the body as they use to travel in the bloodstream to the tissue or the organs. The function of hormones is slow just over the time and they have impact on growth as well as development.

How can changes in trophic levels affect an ecosystem’s health and stability?
Answer:
Changes in the basal levels that are on the bottom of the food chain.
Explanation:
Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.

Scientists are concerned that melting glaciers are exposing long frozen animals. When the ice melts, the animals thaw and begin to decompose. What gas will be produced during decomposition? Will this increase or decrease the amount of CO2 in the atmosphere?
Answer:
Explanation:
During the bloat stage of decomposition of matter, many gases begin to accumulate. These gases include hydrogen sulfide, carbon dioxide, methane, and nitrogen. Therefore since carbon dioxide (CO2) is one of these gases then we can say that yes, the decomposition of the once frozen animals will increase the amount of CO2 in the atmosphere.

Make two fists and place them together so your knuckles are touching each other as shown in the image. Slide one hand toward you and the other hand away from you so your knuckles rub together. What happens? What might happen to two tectonic plates as they move this way?
Answer:
I think it's called "transform"
Explanation:
Answer:
CORRECT ANSWER:
The knuckles represent a jagged surface. When they rub together, they act as obstacles to each other. It’s difficult to move the hands freely as the knuckles catch and release one another. In the case of tectonic plates, if two plates rub, they release large amounts of energy, which can cause earthquakes.

How long does adaptation usually take? (Plant)
1.a decade
2.an hour
3.A few days
4.Centuries
Answer: The answer is (4), centuries
Explanation:
Plant adaptation is a long-term process that occurs over many generations. It is driven by natural selection, which is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce. Hence option D is correct.
The rate of plant adaptation can vary depending on the environment and the plant species. However, it is generally a slow process that takes many years or even centuries to complete.
For example, some plants have adapted to the cold temperatures of the Arctic over millions of years. These plants have developed thick, waxy leaves that help to insulate them from the cold, and they have also developed a slower metabolism that allows them to conserve energy.
Other plants, such as weeds, can adapt to new environments more quickly. This is because weeds are often generalists, meaning that they can survive in a wide range of conditions. They can also reproduce rapidly, which allows them to quickly spread to new areas.
