It is assumed that organisms with similar anatomical characteristics have evolved relatively recently and have a common ancestor.
<h3>How does comparing the physical characteristics of different creatures help us understand evolution?</h3>
To comprehend how living things originated, scientists study the anatomy, embryos, and DNA of various species. Homological structures provide proof of evolution. These are features that were passed down from a common ancestor and are shared by related creatures. An further piece of evidence for evolution is offered by similar structures.
<h3>What role does anatomy play in the study of relationships between various types of organisms?</h3>
Comparative anatomy, which compares structural similarities, is one of the strongest types of evidence of creatures to ascertain the links between them throughout evolution. It is assumed that organisms with similar anatomical traits have evolved from ancestors who were reasonably closely connected to one another.

If the producers were removed then there would be no beginning to the food chain and the complete ecosystem would die off. If the detrivores and decomposers were removed there would be no organic nutrients and all the dead plants would ruin the animals habitat.The ecosystem will be fill by plants and animal wastes as <span>there will be no decomposition of waste material.</span>
The appropriate response is Monosodium Glutamate. Unadulterated MSG is accounted for to not have a wonderful taste to the point that it is joined with an exquisite fragrance. The fundamental tactile capacity of MSG is credited to its capacity to upgrade flavorful taste-dynamic mixes when included the best possible concentration. The ideal fixation differs by nourishment; in clear soup, the joy score quickly falls with the expansion of more than one gram of MSG for each 100 mL.
Answer:
47
Explanation:
We all know that gametes like egg cell and sperm have haploid set of chromosomes but here as per this question she has produced 2 copies of chromosome 21. For the sake of maintaining haploidy, she was supposed to have only a single copy of chromosome 21 as a result of which her egg cell was supposed to have 23 chromosomes not 24.
But, this is a case of non dis-junction. Also, in a normal sperm there are no such copies of any chromosome i.e. there is a haploid set of chromosomes. It means that sperm must be having only 23 chromosomes. So we can easily infer that when the egg cell and sperm will fuse, the zygote will have 47 chromosomes (24 from egg cell and 23 from sperm).
