A kid on a trampoline has 1,000 J of potential energy when they are at the top of a jump. How much kinetic energy will the kid have when they come halfway down?
A. 100 J
B. 250 J
C. 500 J
D. 1000 J
Answers
Answer:
C. 500 J
Explanation:
Given;
potential energy of the kids at the top of the trampoline, P.E = 1,000 J
⇒At the top of the trampoline, the kids have only potential energy.
⇒On half way down, the kids have both kinetic energy and potential energy.
⇒At the bottom of the trampoline, the kids have only kinetic energy.
Based on the statements above, the kinetic energy of the kids half way down is calculate as;
P.E + K.E = 1000 J
Base on law of conservation of energy, P.E = K.E
2 K.E = 1000 J
K.E = ¹/₂ x 1000 J
K.E = 500 J.

The main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.
What is the main characteristic of the bacteria domain?All living things are classified into kingdoms based on specific characteristics found in organisms in that kingdom.
For the bacteria kingdom, the main characteristic present is that they lack a well defined nucleus as well as nuclear membrane.
Organisms without a well-defined nucleus are known as prokaryoytes.
Thus, the main characteristics of the bacteria domain is that they lack a well-defined nucleus and are known as prokaryotes.

Which of the following is a likely impact of this catastrophic event on biodiversity?
Species brought in by the storm surge will displace species native to the coastal wetlands.
Species reliant on coastal wetlands for survival may experience a decline in population due to loss of
habitat.
Coastal wetlands will grow exponentially with the input of nutrients from storm upwelling and biodiversity
will increase in these areas.
Excessive salt from the storm surge will flood coastal wetlands and raise salinity to intolerant levels for the
local species, causing a decrease in biodiversity

A man with blood group B marries with a woman with blood group AB and the daughter has blood group AB. Is this information enough to tell you which of the traits – blood group B or AB is dominant? Why or why not?
Answers
Answer:
YES. This information is enough to assume that neither of the blood groups dominates over the other one.
Explanation:
Available data:
A man with blood group B ----> Genotype IBIB or IBiA woman with blood group AB ---> Genotype IAIBTheir daughter has blood group AB --> Genotype IAIBThe fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.
If blood type B was dominant over A or AB, then the daughter should have Blood type B. If blood type A was dominant over B or AB, then the daughter should have Blood type A. Blood type AB tells us that both types are being expressed, A and B.The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.
This is enough information to assume that neither of the blood groups dominates over the other one.

natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or population? explain
Answers
Natural selection refers to the procedure where the species better amended to their surrounding appear to survive and generate more offspring. Natural selection refers to one of the mechanisms that make modifications in the frequencies of genes in populations and thus, it is the mechanism of evolutionary change.
However, the phenomenon of genetic drift and natural selection cannot take place unless and until there is a genetic variation, that is unless some individuals are genetically distinct from others.
