<u>1</u><u>.</u><u>Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.</u>
<u>2</u><u>.</u><u> </u><u>Bacteria evolve quickly because they grow fast and can share genes. Helpful mutations spread quickly in bacteria.</u>
<u>3</u><u>.</u><u>Taking antibiotics too often or for the wrong reasons can change bacteria so much that antibiotics don't work against them. This is called bacterial resistance or antibiotic resistance</u>

Answer:
Climate change has been described as one of the biggest problems faced by humankind. Carbon dioxide is is the primary driver of global warming. Prof Joanna Haigh from Imperial College London explains why this gas has played a crucial role in shaping the Earth's climate.
Carbon dioxide (CO2) has been present in the atmosphere since the Earth condensed from a ball of hot gases following its formation from the explosion of a huge star about five billion years ago.
At that time the atmosphere was mainly composed of nitrogen, CO2 and water vapour, which seeped through cracks in the solid surface. A very similar composition emerges from volcanic eruptions today.
As the planet cooled further some of the water vapour condensed out to form oceans and they dissolved a portion of the CO2 but it was still present in the atmosphere in large amounts.
Answer:
Genetically modified organisms or GMOs can be characterized as living beings (for example plants, creatures or microorganisms) in which the hereditary material (DNA) has been changed in a way that doesn't happen normally by mating and additionally common recombination. The innovation is regularly called "present day biotechnology" or "quality innovation", now and again likewise "recombinant DNA innovation" or "hereditary designing". It permits chosen singular qualities to be moved from one life form into another, likewise between nonrelated species. Nourishments created from or utilizing GM life forms are regularly alluded to as GM nourishments.
GM nourishments are created – and promoted – in light of the fact that there is some apparent bit of leeway either to the maker or customer of these nourishments. This is intended to convert into an item with a lower cost, more prominent advantage (regarding toughness or healthy benefit) or both. At first GM seed engineers needed their items to be acknowledged by makers and have focused on advancements that carry direct advantage to ranchers (and the food business by and large).
One of the destinations for creating plants dependent on GM life forms is to improve crop insurance. The GM crops as of now available are fundamentally focused on an expanded degree of harvest security through the presentation of obstruction against plant infections brought about by creepy crawlies or infections or through expanded resilience towards herbicides.
Resistance for insects is accomplished by consolidating into the food plant the quality for toxins creation from the bacterium Bacillus thuringiensis (Bt). This poison is presently utilized as an ordinary bug spray in agribusiness and is ok for human utilization. GM crops that inalienably produce this poison have been appeared to require lower amounts of bug sprays in explicit circumstances, for example where nuisance pressure is high. Infection obstruction is accomplished through the presentation of quality from certain infections that cause sickness in plants. Infection opposition makes plants less helpless to sicknesses brought about by such infections, bringing about higher harvest yields.
Herbicide resilience is accomplished through the presentation of a quality from a bacterium passing on protection from certain herbicides. In circumstances where weed pressure is high, the utilization of such harvests has brought about a decrease in the amount of the herbicides utilized.
