The arteries are not a cell bc that is too simple a tissue is also too simple its not a system bc arteries are not a lot of organs working together so its C
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.
Answer:
What is the relationship between increased carbon in the ocean and increased carbon in the soil?
How else might carbon be transferred to soil? Direct because as you increase 1 you increase the other due to the terrestrial plant and oceanic plankton requirements of water, nutrients and CO2.

The answer would be –genesis and –gram.
Suffixes that have a Greek or Latin roots and that are used
to combine with other words or parts of words are not called suffixes, these
kind of affixes are called combining forms.
One combing form is –genesis.
As an independent medical term, this means the origin of
something in medicine. When a doctor talks about the genesis of a contagion, he
or she is speaking of the point of origin of a contagion.
-genesis used as a suffix, can indicate a particular process
or pathogen. Example is parthenogenesis.
One combining form is –gram.
As an independent medical term, gram indicated the metric
weight of an object as a unit of mass. If nurses talk about how much serving of
food, they are talking about it in grams.
-gram signifies something written down. Example is
pictogram.
I think the correct answer from the choices listed above is option A. The relationship between the themes of “place” and “human-environment interaction” is that the characteristics <span>of “place” include things like economic activity, architecture, and culture, all of which are human elements that alter or can be influenced by the environment. </span>
