Aslamulikum and. A very good morning to all of you I'm Ashkhan Azan I'm hear to speak about who is responsible to tackle global warming government or people we know that climate change is caused by human activity but pinning down exactly who is responsible is tricker than it might seem. It is caused by increased concentratioans of green house gases in the atmosphere mainly from human activities such as burning fossil fuels . The responsible for tackling climate change lies with decision-making , industry has been that so far, no agreement has been reached on who should act and how citizens are told to recycle, reduce flying and favour public transport Many groups have been accused of being at blame for this ongoing lack of action from fossil fuel companies and wealthy countries to politicians , rich people and sometimes even all of us​

The herpes viruses are important enveloped dna viruses that cause disease in vertebrates and in some invertebrates such as oysters. some of the human forms are herpes simplex virus (hsv) types i and ii, causing facial and genital lesions, and the varicella zoster virus (vsv), causing chicken pox and shingles. each of these three actively infects nervous tissue. primary infections are fairly mild, but the virus is not then cleared from the host; rather, viral genomes are maintained in cells in a latent phase. the virus can later reactivate, replicate again, and infect others.in electron micrographs of hsv infection, it can be seen that the intact virus initially reacts with cell surface proteoglycans, then with specific receptors. this is later followed by viral capsids docking with nuclear pores. afterward, the capsids go from being full to being "empty." which of the following best fits these observations? a) viral capsids are needed for the cell to become infected; only the capsids enter the nucleus.b) the viral envelope is not required for infectivity, since the envelope does not enter the nucleus.c) only the genetic material of the virus is involved in the cell's infectivity, and is injected like the genome of a phage.d) the viral envelope mediates entry into the cell, the capsid mediates entry into the nuclear membrane, and the genome is all that enters the nucleus.
