A because people can't see the seeds.
MRNA is a single-stranded molecule that carries genetic code from DNA in a cell's nucleus to ribosomes, the cell's protein-making machinery.
The answer is alleles. In addition, the phenotype of an organism is the physical look resulting from the expression of the genes present. The principle of segregation states that substitute alleles for a trait discrete from one another throughout gamete formation and keep on distinct. A diploid organism that has two alike alleles for the same trait is named homozygous for that particular trait.

Question 3
D
Explanation:
1. An ecosystem is MOST likely to return to its original condition after Tall prairie grass burns after being struck by lightning.
Here is a research paper in which they explained how this happened. (Komarek, E. V. (1971). Lightning and fire ecology in Africa. In Tall Timbers Fire Ecology Conference (Vol. 11, pp. 473-509).)
2. In some national parks, controlled fires are maintained by firefighters. The major reasons for using controlled burns to maintain certain ecosystems is to give nonnative plants a chance to colonize the region.
A recent article provided the insight of this situation (Xanthopoulos, G., Delogu, G. M., Leone, V., Correia, F. J., & Magalhães, C. G. (2020). Firefighting approaches and extreme wildfires. In Extreme Wildfire Events and Disasters (pp. 117-132). Elsevier.)
3. One reason for the change in the Galápagos ecosystem has been the introduction of species that were not on the island before, such as donkeys, goats, cats, dogs, and insects. The introduction of nonnative species MOST likely disrupt the balance of life on the islands due to greater competition for limited food sources.
Scientist said that food competition is actually a struggle to survive in any ecosystem here is the reference paper (Eckhardt, R. C. (1972). Introduced plants and animals in the Galapagos Islands. Bioscience, 22(10), 585-590.)
Different kinds of proteins that might be made by the ribosomes are structural, transport, antibodies, storage, contractile protein.
Further Explanation: RNA is Ribonucleic Acid different from DNA by one ribose and RNA is single-stranded. There are different forms of RNAs are present such as mRNA, tRNA, and rRNA.
