Answer:
9:3:3:1
Explanation:
A dihybrid cross tracks two traits. Both parents are heterozygous, and one allele for each trait exhibits complete dominance *. This means that both parents have recessive alleles, but exhibit the dominant phenotype. The phenotype ratio predicted for dihybrid cross is 9:3:3:1. (There's a calculator on google that show the outcomes just to let ya know) hope it's correct .
When faced with a complex engineering problem, the best strategy usually involves( A ) Breaking the problem down into smaller problems and solving them individually.
Explanation:
Th first step of solving a complex problem involves problem identification-it means what exactly is the problem then we try to determine the possible sub-groups in which the problem can be further divided and then numbering the sub groups.
The process of sub-grouping means that we are sub dividing the problems and then working upon the problem that needs the attention first and then according solving the other sub categories of the problem.
This method helps in breaking the complex problem into a series of small task that can be easily solved in a sequential manner .Thus the complexity of the problem gets reduced when it is divided into a number of small problems.
Answer:
B is true .. atmosphere always changes day by day
The reason why stars does not die when it is there time is because they tend to fuse in different and more heavier elements. In that way, it prevents them from dying for they were able to have the components of different elements, extending their lives and prevent themselves from dying on the time that they were supposed to.
The external cell membrane. Even organisms as simple as bacteria have a cell membrane.
Prokaryotes do not have internal membranes but they still have external membranes.
Everything living thing has a cell membrane
