Answer:
The first one has to be the answer
Explanation:
If the area had once been covered by ice or snow, then there would be no place to get the warm leaf from.
If the area was once underwater then I don't know how it would have grown a cold forest, a tropical forest, and then a desert.
It'd make more sense if you started with a cold forest with sharp leaves, that slowly became a warmer forest with smooth leaves, only so it could become a dessert with only leaf fossil remains.
so ya the first one is your answer.
The climate changed from cool forest to hot desert is the hypothesis which can be concluded.
What is Hypothesis?This can be defined as a proposed explanation for a particular phenomenon through various sources.
We were told that the toothed-edged leaf is from a forest in a cooler climate but was found in the desert which therefore means that the climate changed from cool forest to hot desert.

Photosynthesis occurs when 6 molecules of carbon dioxide combine with 6 molecules of water using energy from the sun to form _______ molecule(s) of glucose and release _______ molecule(s) of oxygen into the air.
Answer:
I think the first blank is oxygen. The second blank is nitrogen.
I hope that helped! :)
In net reaction of photosynthesis, one molecule of glucose is formed and six molecules of oxygen is released into the atmosphere.
Why only green plants carry out photosynthesis?Photosynthesis is carried out exclusively by green plants.
Green Plants contain the green coloured pigment called chlorophyll in the mesophyll of their leaves.
This pigment in green plants captures the sunlight in the presence of water and carbon dioxide and converts it into chemical energy.
This energy is stored in the form of glucose and oxygen is released in the air for respiration of living organisms.
Thus, green plants are called as 'producers' on the earth.
All the animals are dependent on green plants directly or indirectly for their food.
In xerophytic plants, (grown in desert) leaves are reduced or absent. In such case the stem is green in colour and performs the function of photosynthesis.
Therefore, green plants are essential for sustaining life on earth.

a) Purpose:
b) Hypothesis:
c) Prediction
d) Describe the basic procedure you would use:
e) How will you collect your data?f) What results would you expect to see from this experiment?
The number of uncamouflaged animals will be far less than that of the camouflaged animals at the end of the experiment.
What is an experiment?An experiment is a detailed study that tends to identify cause and effect relationship.
The hypothesis in this experiment is that camouflage helps animals to survive in their habitat. The predication is that animals that are camouflaged are able to escape predation owing to the camouflage.
The best test procedure is to observe animals that are camouflaged and those that are not camouflaged in the wild for a period of about three months. Observe whether the number of uncamouflaged animals decreased more than that of the camouflaged animals after three months.
At the end of the experiment, it is expected that the number of uncamouflaged animals will decrease far more than the number of camouflaged animals.
The data will be collected using an unmaned drone over the area of study.

How does your body normally gather information for your brain
to process?
Answer:
Using information gatherers on your body such as eyes, nose, mouth, tongue, ears, ect.
Explanation:
Answer:
The brain follows signals through the nervous system. The nervous system sends a signal of what we want to do seconds before it happens, to ensure quick reactions. For instance, when we touch a stove, our nervous system already sent the signal seconds ago in an attempt to prevent your skin cells from being burned off. That is why we immediately pull back from intense heat unless we tell ourselves "wait, no!" before the process is over.
