andreyandreev [35.5K]

Answer:

Please find the similarities and differences between these cells below.

Explanation:

According to this question, six specific cells are examined. They are: neuron, red blood cell, osteocyte, skeletal muscle cell, sperm cell, and egg cell.

SIMILARITIES:

These cells are cells that make up different tissues and systems in living organisms. They perform different functions in their respective locations, however, they are similar in the sense that they all possess some cellular components called organelles. The organelles that are common to all these types of cells are CELL MEMBRANE, RIBOSOMES, MITOCHONDRIA, GENETIC MATERIAL (DNA), NUCLEUS,

They also possess two set of chromosomes in their nucleus i.e. diploid.

DIFFERENCES:

However, they differ in their functions. For example;

- neuron: nerve cell whose function is related to the nervous system

- red blood cell: blood cell whose function is related to circulatory system

- osteocyte: bone cell whose function is related to the skeletal system

- skeletal muscle cell- muscle cell whose function is related to the muscular system

- sperm cell: a male sex cell whose function is related to reproduction

- egg cell: a female sex cell whose function is related to reproduction

1. Describe DDT and summarize the history of the use and banning of DDT, including actions taken by the U.S. government. State t

igomit [66]

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.
