Answer: the answer is choice b
Explanation: based on knowledge about food chains, this choice makes the most sense
Hope this helps, and please give brainliest!
Energy = mass ×specific heat capacity×change in temperature'
In this case, the mass of water is 50 kg, the specific heat capacity of water is 4184J/kg
the change in temperature is 80-45= 35 degrees celcius
Therefore, heat energy
= 50 ×35 ×4184=7322000 Joules
But 1kJ =1000 Joules
therefore, the energy needed will be 7322 kJ
<u>Answer</u>: A) They have been geographically isolated from each other for a longer time.
<u>Explanation</u>: An isthmus is defined as a narrow strip of land that separates two bodies of water as well as connecting two larger landmasses at the same time. Thus, an isthmus if an efficient physical barrier that has separated an original shrimp species. This has resulted in the extant deep-water shrimp species through the evolutionary process known as allopatric speciation.
The age of an isthmus is in the range of at least two million years. Thus, the two deep-water shrimp species have been separated from each other for a very long time.
Answer:
A trait that gives an organism a reproductive advantage in the current environment
Explanation:
- Adaptations are mutations that helps an organism, such as animals or plants to survive in its environment due to a reproductive advantage.
- Adaptations may be structural or behavioral adaptations. Structural adaptations are features or the physical part of an organism that boosts its survival. Behavioral adaptations on the other hand, are responses made by an organism to help it survive or reproduce.
