Answer: Climate change
Explanation:
UN Climate Action Summit 2019 was organized in 2019 to discuss the domain of global climate change research. According to this dangerous impact of climate will influence the growth of new generations to come. This included various participating organizations like World Meteorological Organization, Panel on Climate Change, Earth league and global framework, UN Environment, Global carbon project and others.
<span>because “Barrow is ground zero for climate-change science, and because we worry that climate change is shrinking the sea ice and we don’t know how that will affect the animals that depend on it. But at this time there is no effective plan if a catastrophe such as a ship collision or oil spill occurs. The Coast Guard hasn’t decided what its presence will be in the Arctic. Someone needs to monitor whats going on there.</span>
First of all, it makes algae grow, because pesticides and stuff provide too many nutrients. Algae needs a lot of oxygen and so the fish begin to die off because the algae is taking all the oxygen out of the lake. Next, it causes biodiversity to drop, meaning that species are beginning to get less varied. Water pollution harms the lakes and is a concern because the effects of it on species and the water will stay.
Answer:
In the given case, it can be concluded that very less amount of telomerase is being produced.
Explanation:
Terminal transferase or telomerase refers to a ribonucleoprotein that supplements a telomere repeat sequence to the 3 prime terminals of telomeres. A telomere is present at each terminal of the chromosomes found in the majority of eukaryotes. It helps in safeguarding the terminals of the chromosomes from destruction or from getting combined with the adjacent chromosomes.
Telomerase has its own RNA molecule and works as a reverse transcriptase enzyme. Generally, telomerase is found active in gametes, in stem cells, and in the majority of cancer cells, however, it is generally present in low concentration or is absent in the majority of somatic cells. Thus, the decrease in the ends of the chromosomes suggests that the production of telomerase is taking place at low levels.
The common function shared by alveoli, capillaries and glomerular capsules are lined with simple squamous epithelium so they are all involved where absorption or transport of the materials occur. The function of the squamous epithelium is mainly selective transmembrane transportation either by using the concentration gradient or by active transport by using the membrane bound carrier proteins.
The pulmonary alveoli are highly vascular in structure and are formed by a layer of the squamous epithelial cells and a network of capillaries.
The capillaries are also made up of squamous epithelial cells and gas exchange between the alveoli and blood vessels occurs through these capillaries.
