What roles do humans play in biomagnification?
Answer:
The food chain
Explanation:
Biomagnification affects humans the most because we are at the top of the food chain, thus the accumulated toxins and chemicals are in their largest concentration amongst us.
how can genetically modified bacteria with human genes be used to treat human diseases
In the 1980s, scientists discovered how to produce human insulin by transplanting the genetic information for the human insulin hormone from a human cell, into the DNA of the E. coli bacterium. This reprograms the bacteria to produce insulin, in just the same way as they make their own proteins.
how far does a car travel in 0.75 h if it's moving at a constant speed of 88 km/h
Answer:
Distance = 66 kilometers
Explanation:
Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.
Why do you think hemoglobin levels vary with altitude?
Answer:
haemoglobin in blood increases at high altitude. This is one of the best-known features of acclimatisation (acclimation) to high altitude. Increasing the amount of haemoglobin in the blood increases the amount of oxygen that can be carried.

Does the difference in structure for arteries and veins make sense given then functions? Explain.
(Fossils provide scientists with evidence that allows them to hypothesize how living organisms have evolved over time. Tiktaalik roseae was a unique organism that has been nicknamed the “fishapod” because it is believed to be a species had traits of both fish and tetrapods, the first four-legged animals.)
Which evidence would scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae?
-using transitional forms
-using relative dating
-studying decreasing complexity
-studying analogous structures
Answer:
A. using transitional forms
Explanation:
On Edge 2020
Using transitional forms is the evidence scientist use to make the connection between ancestry of fish and tetrapods using Tiktaalik roseae.
What is Transitional forms?This is referred as the remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group.
The transitional form which is option A is mostly suited as the organisms involved have common traits.

How is a renewable resource different from a nonrenewable one?
A. A renewable resource is more likely to run out.
B. A renewable resource can never be replenished.
C. A renewable resource has a higher demand
D. A renewable re purse is replenished faster than it is used
Answer:
Explanation:
d
A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.
What is a Renewable resource?A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

What does this pyramid tell us about the population?
The answer is A. The population is growing.
The pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.
What is population?Population is defined as the quantity or population of people living somewhere who are a particular social, cultural, economical, ethnic, or racial category. Making decisions can be aided by knowledge of how population parameters, such as size, regional distribution, age structure, or birth and death rates, vary over time.
The pyramid is used to show the growth in population of a country or population of the city. In the pyramid the growth of population is equal in both male and female population. The pyramid shows that the population of older generation is less than the population of younger generation peoples.
Thus, the pyramid tells us that population is growing continuously, the growth of population is equal in both male and female population.

PLEASE HELP!!!!! Describe in detail the process of dna replication
Answer:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
hope this helps
