The dependent variable is the variable which can be manipulated and can affect the independent variable. The dependent variable is on the x-axis while the independent variable is placed on the y-axis. In this case, the x-axis is the number of weeks while the y-axis is the height of the plant.
Answer:
D) Habitats for animals.
Explanation:
It depends what the question means when it says 'the changing of the rivers'. I took it as the rivers are changing size and becoming more spread out. In that case, I chose habitats.
The more water there is, the more habitat there is for sea life.
All in all, the correct answer is D).
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
<span>The main difference between adaptice radiation and other forms of speciationn is : Adaptive radiation happens over a relatively short time.
In natural process of speciation, the perfect mutation could occur within millions of years. In adaptive radiation, the mutation could instantly happenes not long after the radiataion process</span>
Answer:
The correct answer is
1. A rabbit living in a desert has long ears to disperse heat- abiotic factor.
2. A moth immediately dives to the ground when it hears a bat- biotic factor.
3. A lizard stays warm by sunning itself on a rock- abiotic factor.
4. A cactus has spines instead of leaves to help conserve water- abiotic factors.
5. A petunia is bright red to attract hummingbirds- biotic factor.
6. A stick-bug blends in with trees to hide from predators- biotic factor.
Explanation:-
The environment includes both abiotic and biotic factors which can affect the ecosystem. Living elements like plants and animals which affect ecosystem are known as biotic factors while the non-living elements which include air, water, temperature are called abiotic factors.
In the given question the options affected by the biotic factors due to bat, due to hummingbirds and due to predators.
Options affected by the abiotic factors due to heat and due to water.
