The definition to this question is trophic level refers to a level or a position in a food chain or ecological pyramid. It is occupied by a group of organisms that have a similar feeding mode. You can just look it up I here is some help go to this website www.biology-online.org/dictionary/Trophic_level it will tell you all about it
<span>During prophase I, segments of chromatids are exchanged between homologous chromosomes.</span>Crossing over occurs<span> between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes.

The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code
Explanation:
Evaluating the other options given
A.humans and fish evolved from insects
-This option is incorrect as human and fish did not have a common ancestors.
B.
different species synthesize the same proteins
:No this statement also is not the correct option
C.
insects, fish, and humans express the same genes-The expressed genes cannot be same for different species
Hence the correct answer is
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code(As the genetic code is said to be universal
Answer:
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Explanation:
Answer:
Field research and laboratory research are different from each other on various accounts. In a lab, the study is not on such a broader level as that on a field.
Some of the tools in a lab and a field study will be same because such tools cannot be changed. For example, for amplification of genes, PCR will be used whether a field research is being made or a lab research.
On the other hand, some of the tools will be different. For example, to study field plants we'll use quadrants for counting but in a lab, as a lesser number of plants are understudy so we won't need a quadrant.
