Cells have unique characteristics wherein each develop a specific function determined by the activation of certain DNA sequences to generate this specific cell into its supposed design, this is why cell specialization exists.
Hence, these cells can be directly identified with their morphological structures and the DNA sequences they posses.
Well, many times animals may look alike and eat the same food because they are adapting to there invirment. For example there may be many diffrent species of birds that look similar and eat the same food but that does not mean they are of the same kind of bird, over time the birds that have the right body shape to collect food in that invirment will survive while the others perish. This will make the birds look alike while in all they are not of the same species in any way.
Hope this helps
Answer:1 : substratum. 2 : the base on which an organism lives the soil is the substrate of most seed plants. 3 : a substance acted upon (as by an enzyme)
Answer:
Natural selection leads to adaptation, that is, to a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. ... Species become extinct because they can no longer survive and reproduce in their altered environment.
Explanation:
Answer: <u>Option C
</u>
<u>Explanation</u>: Hills are the most common source of sediments because they lack vegetation. Plants and trees hold the soil and thus prevent erosion of soil layer with water. The sediments from the hilly areas get carried by rain water or runoff, and add to the water bodies, like lakes and streams.
Waste from mining industries don’t have sediments in their waste, so option B is incorrect.
Option A is incorrect because over-irrigation will not affect the soil layer, as it is firmly held by the roots of the crops.
