Answer:
Os biofilmes são uma comunidade complexa de microrganismos, que pode ser composta por uma única espécie ou uma combinação de espécies. Os biofilmes são geralmente formados nas superfícies de materiais não vivos ou nos tecidos de organismos vivos; que pode estar externamente nos tecidos vivos dos organismos ou dentro dos tecidos vivos do organismo. Quando os microrganismos formam um biofilme, aumentam suas chances de resistir a anticorpos produzidos pelo organismo e aumentam suas chances de colonização completa do organismo. Algumas doenças são caracterizadas pela presença de biofilmes, que são, na maioria dos casos, a causa da doença.
<em>No caso de obstrução de vasos de plantas hospedeiras por biofilmes bacterianos; os biofilmes se formam na superfície do vaso e aumentam gradualmente de tamanho até que haja uma obstrução completa do vaso da planta. Quando o vaso da planta é eventualmente obstruído, o fluxo de materiais e minerais necessários é obstruído; levando à obstrução das células da raiz de receber materiais vitais e minerais necessários para o crescimento, isso eventualmente leva à morte progressiva das células da raiz.</em>
The correct answer is option A, that is, a landfill in the region of nonporous bedrock.
A permanent waste disposal facility where the wastes are put into the ground and covered with a layer of plastic, soil, or both is known a landfill. A secure chemical landfill refers to a landfill developed in the region of nonporous bedrock.
A secure chemical landfill is a prudently engineered depression in the ground or constructed on the top of the ground, signifying a football stadium into which wastes are dumped. The objective is to inhibit any water-related or hydraulic association between the surrounding environment and the wastes, mainly groundwater.
El Niño as evidence of potential dangers of global warming to marine ecosystems
Explanation:
El Nino, an abnormal type of weather pattern, causes huge climatic variations globally by bringing floods in one region and drought in another region. These extremely changing patterns in weather can damage human life, agriculture, air quality, natural ecosystems, etc all of which might lead to global warming.
El Nino effect is a serious potential danger to the marine life. This causes variations in the sea surface temperature, ocean currents, and upwelling patterns. Due to this, many marine organisms either migrate to newer places or do not survive the change.
Due to this, other sea animals depended on them also are depleted of their food source. El Nino also impacts the structure of coral reefs causing coral bleaching which in turn affects the marine life.
Answer:
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.
<span>How might an increase in the rate of photosynthesis affect the conditions necessary for cellular respiration? Increased oxygen and glucose from photosynthesis would increase cellular respiration. Increased water and carbon dioxide from photosynthesis would increase cellular respiration. Increased water and carbon dioxide from photosynthesis would increase the amount of convertible ADP. Increased carbon dioxide and glucose from photosynthesis would increase cellular metabolism</span>
