Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end-diastolic pressure and volume.
The following questions are answered below.
Explanation:
a. They have 14 chromosomes that occurs in 7 pairs which has X and Y sex chromosomes. They are diploid.
b. They have 7 pairs of chromosomes that includes X and Y sex chromosomes. They are diploid.
c. The last pair of chromosomes are the sex chromosomes. The previous pairs are called the autosomes.
d. If the Tasmanian devil has 14 chromosomes , then it is a boy. If the Tasmanian devil has 28 chromosomes , then it will be a female.
e. The one extra chromosomes are the egg or sperm that means three in fertilized egg. They are called as Trisomy.
f. The Tasmanian devil's will not get Down syndrome but some times there may be trisomy if there are three chromosomes instead of two.
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
You can use genetic engineering techniques to make transformed bacteria that produce this enzyme by a<span>llowing bacterial cells to take in the plasmids and select for transformed bacteria by growing them in a culture containing the antibiotic.
