Answer:
The correct answer is C: competition for resources
Answer:
The independent variable is the projection of yhe light rays, and the dependent variable is the refraction and bending
Answer:
3 characteristic
Explanation:
1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.
2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.
3- Motility: if bacteria are motile than it's motility is easily visible in the media.
Answer:
Biology is an interesting subject that has been intriguing scientific minds for several centuries
Explanation:
Despite exponential developments in technology over the past few centuries, the origin of life on earth is still one of the biggest mysteries yet to be unraveled.
The basis of our very origin and existence on earth lies within the depths of the biological sciences. Biology has an endless array of species( at least as of now because there are an estimated 8.7 million species on earth out of which only 1.9 million species have been discovered, so there is a long way to go!).
Every creation which is a part of nature is so adorable and unique in its own way.
Biology exists every second - when we inhale and exhale each time, respiration is taking place within our bodies, each cell receives oxygenated blood and releases carbon dioxide and other excretory wastes.
Let aside other species, we haven't yet understood our own bodies completely!!How is it that our hearts work so tirelessly throughout our life span, how is it that we are able to interpret even minute emotions and gestures without even understanding the mechanism behind it!.How is it that each one of us is able to perceive things differently?What exactly is consciousness?..The list of questions seeking their answers is endless!
Biology helps us to sort things out and find answers to such questions.
Humans aren’t the only living things biology is concerned with. It also tells us all about plants and animals – how they live, what they’re made up of, and how they interact with mankind and each other. This enables us to make the most of our planet’s natural resources while trying to minimize the impact we have on the environment.
The best explanation for this unchecked population growth is that the predators are too few to slow down population growth of mussels. The environment limits population growth by changing birth and death rates. The factors affecting population size and growth include biotic factors such as food, disease, competitors, and predators and abiotic factors such as rainfall, floods, and temperature. Predators affect individual growth rates of surviving prey by acting to increase growth rate by thinning the density of prey populations, which releases survivors from competition.<span />
