Nuclear power can be used in Radioisotopes,Plant mutation breeding,and Insect control
A they are non-cellular they can’t make their own energy and only living host cells have the ability to mutate
Answer:
Explanation:
The correct pairing of the homologous chromosomes and their correct segregation (a chromosome for each daughter cell) are key to the proper development of the new cells, and specially of the new individual if we are talking about the early stages of embryogenesis. If there is an error during the splitting of chromosomes, and one cell gets a double set and the other misses a chromosome, numerical chromosomal abnormalities occur. These numerical abnormalities can happen on autosomes or sexual chromosomes, and common examples are as Down Syndrome (trisomy 21), Patau Syndrome (trisomy 13), Turner Syndrome (45,X) and others.
The number of the trisomy indicates the chromosome pair that suffered the adding or the subtraction of its chromosome.
By using a genetic diagram or a punnett square, we can show the the result of a cross between RR and rr.
The result of the genotypes should all be Rr.
This means all their offsprings should have the dominant trait being expressed.
Therefore, the percentage to this should be 100%.
The picture above is an example of using a punnett square finding the possible genotypes of the offsprings.
Answer:
1-Ecological succession is the process of change in the species structure of an ecological community over time.
2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.
