MY SCHOOL WORK IS DRAINING THE LIFE OUTTA ME
"Mesotherms could be outcompeted for prey by similarly sized endotherms in similar niches. Mesotherms may also require more energy compared to ectotherms, which would put them at a competitive disadvantage if energy was a limiting factor for growth."
Answer:
The correct answer is - sporophyte and gametophyte.
Explanation:
In seed producing plants such as gymnosperm and angiosperms the sporphytic part of life cycle is more dominant than the gametophytic part of life cycle. Sporophyte life cycle arise just after the formation of the zygote formation from fertilization of the gametes. The seeds are sporophytic structure that are dispersed to grow and be a full sporophytic plant with root, stem and leaves.
In mosses and ferns the case is different as there are no seed forming present the spores that are gametophytic as has n number of chromosome disperse to produce gametophytic plants that are comparatively small to sporophytic ones.
Thus, the correct answer is - sporophyte and gametophyte.
Answer:
Comparative biochemistry. (Ans. B)
Explanation:
Comparative biochemistry: It is defined as the study of evolutionary relationship present between organisms, by comparing the deference, and similarities present in these genes. It is helping in the study enzymes, and protein machines, but both are encoded with the help of DNA sequences. It is helping to determine the comparison of the structure of cytochrome c from different organisms to infer evolutionary relationships.
Genes are inherited to offsprings from parents, and made up of DNA. Some DNA are codes for mRNA, later they are helping to code amino acid sequence of protein. Cytochrome C involved in using energy in the cell, and it is a protein.
