Answer:
<u>Option -</u> An open circulatory system inside the adults.
Explanation:
- A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. A knowledgeable zoologist should predict that the adults of this species would also feature <u>an open circulatory system</u>.
- Most of the invertebrates like the insecticides have the open circulatory system, as the system has no specific pathways for the transportation of the materials and other essential nutrients through the medium but they have a more different mechanism in order to provide the sufficient materials to survive.
DDT stands for dichloro-diphenyl-trichloroethane. The first kind of synthetic/artificial insecticides came into use in the 1940s. The earlier usage of DDT include: a) Killing of malarial vectors, b) Combatting Typhus and other insect borne human diseases, c) As a pest control in crops d) as a pest control in garden, live stock production and even at homes.
The negative impact of DDT could be felt for the first time when the pests that were earlier killed by use of DDT have now become pesticides resistant. In the 1950s in USA, the regulatory measures were adopted to reduce the usage of DDTs as its effects as a pesticides were no more long significant and also it was creating detrimental physical and psychological impacts on the human and environment.
It was in 1972 that the U.S. Environmental Protection Agency cancelled the order for banning the usage of DDT based on the adverse impact it produced on the environment, human and other life forms. Since then continuous studies are being conducted to analyse the impact of DDTs. In some later years it was established that DDT is the cause of producing tumors in liver.
Some of the common negative impacts produced by DDT as per the U.S. Department of Agriculture :
a) The non destructive nature – DDT can not be destroyed and thus it remains persistent in the atmosphere
b) It attacks the tissues of living organisms especially the animals and humans ( fatty tissue)
c) It can penetrate the atmosphere to deeper extent.
Now as per the current stuation, The use of DDT is controlled and other alternatives of pest control organisms is being deduced. As per the treaty of Stockholm Convention on POPs (Persistent organic pollutants) , usage of DDT for malarial control is justified but it puts a restrictive use of DDT as pesticides in other areas.
<em>both producers and consumers are the part of ecosystem but finally either directly or indirectly they become food of the decomposers that may be micro-organisms or the larger parasite or saprophyte ..
organisms taking food from living host are parasite while taking food from dead matter are saprophytes..</em>
Answer:
<u>Starch</u> is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.
<u>Cellulose </u>is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.
<u>Glycogen</u> is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.
Explanation:
All of these sugars are polysaccaride sugars containing large number of glucose subunits.
Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.
Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.
Cellulose is the storage form of glucose in plants and leaves.
The correct answer is Shrubland.
Jane and her family is going to visit shrubland biome. This biome generally get more than land than the desert and the grasslands but the rainfall is less than forested area. Some places that are found surrounding the Mediterranean Sea is California, Mexico, Chile, et cetera.
