Answer:
For example, the Everglades ecosystem provides drinking water for one-third of Floridians and irrigation for much of the state's agriculture. The wetlands improve water quality by filtering out pollutants and absorbing excess nutrients, replenish aquifers, and reduce flooding.The Everglades is a unique treasure found in South Florida. The Everglades is the largest remaining subtropical wilderness in the United States. It consists of 1.5 million acres of saw grass marshes, mangrove forests, and hardwood hammocks dominated by wetlands. It is home to endangered, rare, and exotic wildlife.
<em>PLATO </em>
A.
The population's birth rate falls below its death rate after a predator is introduced.
B.
A lack of mating opportunities increases the population's level of emigration.
<u><em>C.</em></u><em> </em>
<em>An increase in food availability increases the birth rate in the population.</em>
D.
The population's level of immigration falls below its level of emigration.
Answer:
convergent evolution
Explanation:
Convergent evolution is a feature of organism to develop similar traits as other animals in order to adapt to their habitat. Similarly to bats and birds both developing "wings".
The thumb-like appendage in a panda is actually a false thumb. Since Giant pandas require a large amount of bamboo to maintain life. They must be very efficient in tearing and stripping the leaves for fast feeding. Pandas that developed this trait were better able to survive and pass this along to their offspring.
It is called Denaturation.
Answer:
Sex linked trait
Explanation:
Sex linkage is the phenomenon in which the expression of genes depends on the gender of the organisms because genes for specific traits are located on the sex chromosomes of organisms. If repeated crosses of the fish indicate the pattern that long tail fins appear only in males and not in females, it means the trait is linked to the male sex.
What are sex chromosomes:
They are usually a pair of chromosomes present in higher organisms like humans and other mammals that combine during fertilization of male and female gametes and determine the sex of offspring. In humans they are X and Y chromosomes and when there is an XX offspring, she will e female and when there will be XY offspring , he will be male.
Significance:
- Now there are some genes that are present only on sex chromosomes of the organisms like genes for beard are present in human Y chromosome of men, However,genes found on the X chromosome can be found in either males or females.
- Sex linked genetic disorders are very common in human males because males receive only one copy of X chromosome while females receive two copies. So only one copy of defective gene is enough for the expression of disease in males while in women two copies are needed if the trait is recessive.
- For example: There is a disease called hemophilia in which the blood is unable to clot even after minor injuries and can be life threatening.
- Hemophilia is an X linked recessive disorder and is an example of sex linked traits controlled by sex linked genes.
