The most plausible hypothesis is: Tropical regions generally have more available water and higher levels of solar radiation. They also have very high rates of immigration and very low rates of extinction.
explanation:
Water is essential for an abundance of life, and sunlight is the means by which the whole food chain receives energy. Plants convert the sunlight into food, herbivores eat them, and other animals eat herbivores.
Hope this helps, and muchas luck on your biology.
Answer:
1. first part Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins or other molecules, it is called gene expression. second part Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide are attached to the nitrogenous bases within another polynucleotide by way of special chemical bonds called hydrogen bonds.
2. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.
3. Non-coding DNA sequences do not code for amino acids. Most non-coding DNA lies between genes on the chromosome and has no known function. Other non-coding DNA, called introns, is found within genes. Some non-coding DNA plays a role in the regulation of gene expression.
Answer;
-Our brains fill in gaps in our perception.
-If its been a long time since an event occurred, we might imagine things that did not happen.
Explanation;
-One way that our brain may alter sensory information is by filling in information that is not really there. For example a word in a sentence could have a missing word but we probably assume that word is there and keep reading the sentence.
-Another way is applying already known stuff into new situations. For example we have learned that if a dessert is pink, then it is strawberry flavored. If we saw a bowl of vanilla ice cream with pink food coloring, we may assume it's strawberry ice cream.
Answer:
Photosynthesis produces: <em>glucose </em><em>and </em> 
...from 
, energy (light) and 
Respiration produces: energy (ATP),
....from <em>glucose </em><em>and </em><em />
<em />
Explanation:
These end products, namely and glucose are then used in respiration...
Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.
They combine light energy from the sun, water, and carbon dioxide.
6 + 6 + (energy) →
+ 6
In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

The waste products, and , result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants and in respiration.
