Answer:
The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). Rainfall: The word “rainforest” implies that these are the some of the world's wettest ecosystems.
Usually, the best practices would dictate that a guest account would be placed in a secure network, isolated from the production network by firewall barriers. If it is impractical, then specific areas of access should be determined and they should be as restrictive as possible.
Answer:
a) Mean - 10
b) mode - 9
c) Median - 9
d) SD - 2.708
Explanation:
A) Mean is the average of a given set of number in which the sum of all the number is divided by the number of entries
Thus, mean is equal to
B) Mode is the most common number in a given series
Thus, mode is equal to 9 as it has appeared twice
C) Median
Number are arranged in ascending order
7, 8, 9, 9, 10, 12, 15
The middle number is the median i.e 9
D) Standard Deviation
Formula is square root of sum of 
divided by 
Variation is any difference in organisms of the same species, whereas gradualism is a microevolutionary theory.
<h3>What is a scientific theory?</h3>
A scientific theory is a given explanation on a phenomenon from the real world (e.g., the evolution theory).
The fossil record is a piece of evidence for the evolution theory (which is mainly based on natural selection).
In conclusion, variation is any difference in organisms of the same species, whereas gradualism is a microevolutionary theory.

Answer:
COOH (carboxyl group)
Explanation:
The amino acid backbone is common/ primary to all amino acids and the R-group is what makes each amino acid unique. The alpha-carbon is central and is connected to the amino group (NH3+), Carboxylic acid group (COOH), Hydrogen (H) which form the backbone and the R-group which differs in each amino acid.
