Scientists routinely explore whether two different animal species have evolved from a recent common ancestor.Comparisons of items eaten for food is the LEAST useful technique to help with this determination
<h3><u>
Explanation:</u></h3>
The features that are related to the anatomy of two organisms when they share them in common indicates that they are evolved from the common ancestor. When there exists a common feature between any two species physically then it is inherited form the common ancestor.
The two species having common traits involves similar genetic material called DNA, genetic codes that are similar and same translation and transcription process. Thus studying about genes and gene expression will be helpful to explore whether two different animal species have evolved from a recent common ancestor than including the studies related to Comparisons of items eaten for food.
Answer: microorganisms
Explanation: No animal has the ability to digest cellulose directly.
Most animals such as horses and termites cannot directly digest cellulose. The animals have a symbiotic relationship with bacteria in the intestinal tract. The symbiotic bacteria acts on the cellulose and secrets the necessary enzymes (cellulase) to digest cellulose in the intestinal tract. An example of such microorganism in a symbiotic relationship with animals that facilitates the digestion of cellulose is Trichonympha
Answer:
I believe the answer is 2
Answer:
The correct answer would be the experimental group.
There are mainly two groups present in any experiment; the experimental group and the control group.
The experimental group refers to the group which receives experimental procedures or is exposed to the independent variables to be tested.
In contrast, the control group refers to the group which is kept in controlled conditions, that is, it is not exposed to the variables which are being tested.
