Answer:
A. Flowers that bloom in different months
Explanation:
Nature has a way of preventive the interbreeding of closely related species and temporal isolation is one of them. When species reproduce at a different time there is little chance of hybridization (intermixing) between two related species. Since this process occurs before the mating it is also termed as pre-mating isolation.
Answer:
a.) Flowers that bloom in different months
Explanation:
Hello,
Temporal isolation is exposed when two populations are isolated by cause of when they do perform actions according to their instinct. This is considered as large a difference as mating seasons and as small a difference as what time of day they are active. Isolation makes it less likely for two populations to reproduce together, that's why flowers that bloom in different months is a clear example of this biological event.
Best regards.
Answer: nuclear fusion
Explanation: It is a nuclear fusion because a fusion is when two join together and fission is when one thing splits into two.
methane and water
B.
oxygen and carbon dioxide
C.
methane and oxygen
D.
carbon dioxide and wate
Methane is a hydrocarbon, hydrocarbons burning in the presence of oxygen results in a combustion reaction that yields a large amount of energy
balanced equation for the combustion reaction for methane is as follows
CH₄ + 2O₂ --> CO₂ + 2H₂O
the products of the reaction as stated above are
CO₂ and H₂O
answer is
D.carbon dioxide and water
b) [Ha} < [A-]
c) [HA]=[A-]
The correct scientific notation form of the number 5,489.6654 using only 2 significant figures is: 5.5 * 10³
Scientific notation is a way to represent very large or very small numbers in a more concise and manageable format. It consists of two parts: a coefficient and an exponent of 10.
In your given number, 5,489.6654, we want to express it in scientific notation using only 2 significant figures. Significant figures are the digits in a number that contribute to its precision.
Identify the significant figures: From the given number, we have two significant figures, which are 5 and 4.
Determine the coefficient: To represent the number in scientific notation, we want the coefficient to be between 1 and 10. In this case, we can round the number to 5.5 (rounding the 8 up).
Determine the exponent of 10: To express the number 5.5 in scientific notation, we need to move the decimal point in the original number to the right by one place.
