Answer:
Factors include: food availability, predator density and disease risk. Density-independent factors are not influenced by a species population size. All species populations in the same ecosystem will be similarly affected, regardless of population size. Factors include: weather, climate and natural disasters.

which trait became more common over time why do you think this happened
Answer:
Whether an allele is dominant or not does not affect how common a trait is. Now of course traits can become more common over time. The changes just don’t have anything to do with whether the trait is dominant or not. If brown eyes gave an advantage, then it would start to become more common.
Explanation:
Traits that provide advantage to the organism become more common over time due to natural selection. Therefore, traits become common due to natural selection.
What is natural selection?Due to natural selection, traits that are desirable to an organism and help in its survival in an environment and allow them to reproduce successfully become common over time which help them to acclimatize more successfully.
For example, in a population of birds that feed on insects, some birds have longer beaks while some have shorter beaks. successful at obtaining food and surviving than birds with shorter beaks. Birds having longer beaks will feed on insects more easily than the birds with shorter beaks.
Longer-beaked birds with period of time will become more common in the population as they outcompete other birds for resources. Natural selection is influenced by various factors, such as genetic drift, gene flow, etc.
Therefore, desirable traits that are necessary for population will become more common over time due to natural selection.

Explain how plants and humans are interdependent using the words cellular respiration and photosynthesis.
Answer:
Explanation:
Humans need oxygen to respire and plants need carbondioxide to photosythensize. So plants produces oxygen as product during photosythensis which humans need for respiration and humans also produces carbondioxide as product during respiration which plants also needs for photosynthesis

Cyanobacteria can cluster together into colonies called _______, with some discovered in Western Australia that are 3.5 billion years old. Cyanobacteria produce oxygen and convert sunlight to energy using _______. Plants and arthropods didn't make the transition to land until near the end of the _______ Period. Diverse multicellular eukaryotes didn't appear until the _______ period. A large multicellular eukaryote requires more _______ to survive than a single-cell eukaryote. Respond to the following based on your reading. Describe the biological chemical processes that were responsible for producing oxygen in Earth's atmosphere, eventually leading to the Cambrian Explosion. Explain the importance of oxygen in the evolution of large multicellular animal life.
Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.
