Imagine you are a paleontologist trying to find the "missing link" between different species. in three to five sentences, create a fictional narrative about your discoveries, describing: 1) what two species, mythical or real, you are studying, 2) what evidence you have linked these species, and 3) what evidence you have to define different correlations and causations that support your hypothesis.
In this question, let's imagine that we are a paleontologist trying to find the "missing link" between cockroaches and shrimp.
Missing linkA paleontologist is trying to find the "missing link" between the cockroach and shrimp, the evidence is that both have similar body disposition, but one lived in the sea and the other on land, the evidence he has to define different correlations and causes that support their hypothesis are that these two animals are close in taxonomic classification and have similar body structure.
With this information, we imagine that we are a paleontologist trying to find the "missing link" between cockroaches and shrimp.

Explain the general process of nuclear fission. what is created from fission? (site 1)
Answer:
During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits. These neutrons continue to collide with other uranium atoms, and the process repeats itself over and over again.

Which of the following do you think will contain DNA? Explain your reasoning. bananas __ concrete __ fossils __ meat __ metal __ spinach __ strawberries __
Answer:
fossils, meat, spinach, strawberries
Explanation:
They all were reproduced so they have cells.
Answer:
-bananas
-fossils
-meat
-spinach
-strawberries
Explanation:
These are (or were once) living things, and so they will have DNA. Most living things have DNA, it is like a code on how they were made. The DNA tells us what specific characteristics an animal, plant or other living thing has/had.
For the fossils, the living thing that the fossil depicts wasted away and the fossil was left behind. The fossil had touched the living thing, therefore it had to have left at least a trace of DNA from the original organism.

A car goes 65 km/h for 4.5 hours. give the distance covered by the car.
Answer:
292.5 km
Explanation:
In order to solve this problem, we will simply need to multiply the amount of miles driven in an hour, and how many hours.
The formula is: Distance=Speed x Time
In this case:
Speed: 65 km/h
Time: 4.5 hrs
Now, we will just need to multiply. 65 x 4.5 = 292.5
The answer is 292.5 km.

your friend argues that there is no need for scientific names for organisms and that the existence of both scientific and common names will only confise people. Explain why we have both
Answer:
Scientists and researchers need to have a "universal language", so they can communicate with others around the world. They use scientific names that normally have Latin origins.
The reason we use common names is so people don't get confused. Normal people won't go around saying they need to walk their canis lupus familiaris. They'd say they need to walk their dog.

What is meant by the term "osmosis"?
Answer:
Explanation:
Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane. Any solvent can undergo the process of osmosis including gases and supercritical liquids.
Answer: in biology Osmosis is the carriage of a solvent through a semipermeable membrane that separates two solutions of differing solute concentration. During osmosis, the solvent moves from the solution so that lower in solute concentration to the solution that was highest in solute concentration.
