Which of the following is a factor in natural selection?
A. Individuals of species compete with one another to survive.
B. Individuals better able to adapt to changes leave more offspring.
C. All species are genetically diverse.
D. All of the above.
Answer:
D.
Explanation:
Although all of these answers are similar, it seems that all three are the answer. I am sorry if the answer ends up being B but I'm pretty sure the answer is D. Charles Darwin's evolution theory "evolved", get it, from the natural selection theory. The theory is described as "the process whereby organisms better adapted to their environment tend to survive and produce more offspring." However, some factors that effect natural selection are competition, selection and variation. I believe all three fit the answer and therefore I believe answer D is correct.
The factors in natural selection are Individuals of species compete with one another to survive, Individuals better able to adapt to changes leave more offspring and all species are genetically diverse. The correct option is D.
What is natural selection?The process in which organisms have adapted to their environment and tend to survive and produce more offspring.
In the natural selection, the species have competition with each other to survive in their adaptation. The diversity in species have their different adaptations. They generally adapt to new changes in their habitation.
Thus, the correct option is D.

What is the relationship between "freezing point" and "melting point"?
**Explain your thinking below using quotes from the text.**
~You will get reported if you answer with something else~
Answer:
The freezing point of a substance is the same as that substance's melting point. At this particular temperature, the substance can exist as either a solid or a liquid. At temperatures below the freezing/ melting point, the substance is a solid.
Explanation:
edge 2021
Answer: The relationship between freezing point and melting point is that freezing point is at the temperature of when a liquid freezes and melting point is at the temperature when a solid melts which are both at the same temperature
Some quotes from the text to support this is that: "Freezing point is the temperature at which a liquid freezes and melting point is the temperature at which a solid melts.

explain one or two things that adversely (negatively) affect the Earth's environment. How do you know that these things you're discussing are bad for the world around us?
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Answer:
Hello! The main thing I will be talking about today is two things that negatively affect the Earth's environment. Humans have impacted the physical environment is many ways, two being, overpopulation. Overpopulation is becoming a problem in this world. Accidental births are the main reason. Overpopulation can cause economic problems, over-farming, deforestation, and even water polluting. Second thing is, burning toxic fumes, and creating pollution. Pollution is a very, very bad thing. It can cause the atmosphere to fill up with fumes which aren't good for plants, humans, or animals. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. There are four main types of air pollution sources: mobile sources, such as cars, buses, planes, trucks, and trains. stationary sources, such as power plants, oil refineries, industrial facilities, and factories. area sources, such as agricultural areas, cities, and wood burning fireplaces. I know the things I'm discussing are bad because, slowly the Earth is taking impact because of us. We need to make a better change and help our Earth.
Scott made a model of the water cycle by filling a tub with water, covering the tub with clear plastic, and placing a heat lamp over the tub. After a few days, he observed water droplets collecting on the plastic wrap.
What process formed the water droplets in Scott’s model?
evaporation
transpiration
condensation
precipitation
The phase change process of condensation formed the water droplets in Scott’s model.
What is condensation?Condensation is a process of phase change in which gas molecules are converted to liquid molecules.
Condensation occurs due to the loss in heat and hence kinetic energy by the gas molecules.
In the water cycle model, after evaporation occurred in the water molecules, the process of condensation
formed the water droplets.
Therefore, condensation resulted in the formation of water droplets on the model.
