Answer:
Let's complete the question by writing the sequence, from earliest to most recent options
a. 2 → 1 → 3 → 4
b. 2 → 4 → 3 → 1
c. 2 → 3 → 1 → 4
d. 2 → 1 → 4 → 3
e. 2 → 4 → 1 → 3
It's surely going to be e.
e. 2 → 4 → 1 → 3
2. Cambrian explosion occurs.
4. Vertebrates become top predators in the seas.
1. Protostomes invade terrestrial environments.
3. Deuterostomes invade terrestrial environments.
Got it!
Grasses are the producers. Gazelles, warthogs, and wildebeests are primary consumers. Lions and cheetahs would be the secondary consumers.
Answer:
I think that birds have different bill lengths because of their habitats and their diet. Also natural selection and evolution has also played a factor due to the fact that birds have not always looked the way that they do now, for example the Archaeopteryx a bird that lived around the time of the dinosaurs had a shorter and more powerful bill to grind insects and small mammals
Explanation:
Answer:
A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.
So there are a lot of things that can impact on how we see the graph of the same data.
About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.
The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.
Answer: 4.6 billion years.
