Answer:
They're still VERY relevant.
Explanation:
In 2019, an estimated 34,800 new HIV infections occurred in the United States. HOWEVER new HIV infections declined 8% from 37,800 in 2015 to 34,800 in 2019. In 2012, the US Food and Drug Administration gave the green light to using daily pills of an HIV medication called Truvada (emtricitabine/tenofovir) to prevent infection. It proved more than 85% effective when taken on schedule. New drugs are still being developed, here's a link from the
FDA explaining some different types of new TREATMENT medications:

Here's a link for medications that PREVENT HIV/AIDS:

Answer:
C) 86 J of energy for every 100 J that enter it.
Explanation:
Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:
Efficiency = energy output/energy input x 100
If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.
The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.
Hope it helps!
Answer:
The addition of a water molecule breaks a covalent bond between sugar monomers
Explanation:
The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction.
Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.
The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.
Answer:
D. Lots of vegetation
Explanation:
Urban heat islands form when cities replace natural land cover with dense concentrations of heat-absorbing pavement, buildings, and other surfaces. This has the impact of raising energy prices (for example, air conditioning), air pollution levels, and heat-related sickness and mortality.
