The answer is constipation,backache,pelvic pressure and frequent urination.im not sure about the answer
In an animal cell, DNA is found in the greatest concentration in the Nucleus.
Answer: Nutrient enrichment had definitely impact animal life and leads to destruction of their natural habitat and curtails growth.
Explanation: The nutrients that are infused into the soil to enrich it can hamper a lot of on the surface level as well the organisms which are affected eventually.
The upstream of the nutrients reaching the coastal ecosystems which leads to
- poisoning of the shellfish
- toxic algae blooms
- destruction of the coral reefs
The impacts that it will have on
- trophic structure
- trophic interactions
- trophodynamics of phyto planktons, zooplankton and the benthic communities of the coastal ecosystems.
The prediction is gloomy as over the years it could lead to major shifts in animal life and have a larger impact on the environmental change that would be irreversible.
The nitrogen levels are peaking which is over-enrichment and more susceptible environments are bearing the and results show that now dead zones are being identified.
the oxygen levels get lowered resulting in the death of fish
It's exon. Just took the test.
Answer and Explanation: The figure below shows the doses of BPA administered to the female mice over time.
An experiment is used to determine cause and effect among variables. When the research is for the impact of a treatment, researchers randomly separate individuals in two groups:
- <em><u>Control</u></em> <em><u>Group</u></em> doesn't receive any treament or a placebo or a treatment whose outcome is already known;
- <em><u>Treatment</u></em> <em><u>Group</u></em> receives the treatment;
For the female mice on the image below, in the First Group is not injected any dosage of BPA, so they are the control group, while the <u>others</u> are <u>treatment group</u>.
The variables in a experiment are classified as independents or dependents:
- <em><u>Independent</u></em> <em><u>Variable</u></em> is the cause;
- <em><u>Dependent</u></em> <em><u>Variable</u></em> is the effect;
For the BPA research, since it is the effect of BPA over time on the mice's cells it is being investigated, <u>dosage</u> of BPA is the <u>independent</u> variable and <em>time</em> is the <em>dependent</em> variable.
