The kingdom is called prokaryotic cells, they are very simple cells. They lack a membrane bound nucleus, mitochondria, or any other membrane-bound organisms.
Options for the question have not been given. They are as follows:
A) 1/8
B) 3/4
C) 1/16
D) 1/2
Answer:
D) 1/2
Explanation:
Let the allele for extra digits be represented by D. Since it is a dominant trait, DD and Dd will result in extra digits whereas dd will result in normal number of digits. The woman has normal number of digits so she has dd genotype. The man has extra digits so he can be either DD or Dd.
The couple's first child has normal number of digits so she has dd genotype. She has obtained one d allele from her mother and another d allele from her father. Hence, the man's genotype is Dd.
Man = Dd
Woman = dd
Their children :
D d
d Dd dd
d Dd dd
Half of the progeny will have Dd genotype and will have extra digits. Other half will have dd genotype and will have normal number of digits. So, the probability of their next child to have extra digits is 1/2.
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.
The Mantella frog of Madagascar and the poison dart frog of South America share the same characteristics but they live in different ecosystems. The two frogs live in the same type of niche, eat the same type of food and have similar defense mechanisms. Therefore, if a group of mantella frogs are transported to the ecosystem of the poison dart frogs, the two populations will be involved in competitive exclusion, that means that, both frogs will fight for the same resources and the better suited frog will survive. Thus, the population of the ill suited frog will decrease.
