Answer:
Human impact on coral reefs is significant. ... Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Other dangers include disease, destructive fishing practices and warming oceans.Factors that affect coral reefs include the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, viruses, impacts of dust storms carrying agents to far-flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal areas. Climate change, such as warming temperatures, causes coral bleaching, which if severe kills the coral.
In 2008, a worldwide study estimated that 19% of the existing area of coral reefs has already been lost, and that a further 17% is likely to be lost over the subsequent 10–20 years.[3] Only 46% of the world's reefs could be currently regarded as in good health [3] and about 60% of the world's reefs may be at risk due to destructive, human-related activities. The threat to the health of reefs is particularly strong in Southeast Asia, where 80% of reefs are endangered. By the 2030s, 90% of reefs are expected to be at risk from both human activities and climate change; by 2050, it is predicted that all coral reefs will be in danger.
The products that are derived from invertebrates are the following:
1. food - crabs, lobsters, oysters, octopuses: all of these are invertebrates (meaning they have no spine) and are used as food
2. shell - seashells are invertebrates and their shells are used for various purposes
3. jewelry - shells are used as jewelry, as well as pearls coming from seashells
4. silk - silk comes from silkworms, which are invertebrates
I just wouldn't pick cotton, because you get cotton from a plant.
The earlobe trait is denoted by E and e alleles, whereas the eye trait is denoted by B and b alleles. The Punnet square allows identifying the expected proportions in the progeny.
<h3>The Punnett square and inheritance </h3>
The Punnett square is a diagram used to represent the gamete combinations in order to estimate genotypes and phenotypes in the progeny.
The earlobe trait is denoted by E and e alleles, thereby there are two types of gametes in heterozygous individuals.
In this case:
E e
E EE Ee
e Ee ee
Moreover, the eye trait is denoted by B and b alleles, thereby there are two types of gametes in heterozygous individuals.
In this case:
B b
B BB Bb
b Bb bb

Fruit growing have following economic and
nutritional advantages. High productivity: High
yield per unit area: From a unit area of land more
yield is realized from fruit crops than any of the
agronomic crops. The average yields of Papaya,
Banana and Grapes are 10 to 15 times more that of agronomic crops.
