Answer:

Forest ecosystem

Explanation:

The forest ecosystem refers to the thick woodland that is comprised of both living and non living things and their interaction between each other within that ecosystem.

This forest ecosystem may be damaged drastically due to forest fire, killing the animal species that exist there. It also reduces the amount of plants and trees, leading to the loss of habitat for animals. The fire in the forest is produced mainly due to the human activities. In addition to this, they are also produced due to lightning, volcanic eruptions or sparks that creates from the falling rock.

frosja888 [35]

Earth’s atmosphere had little to no oxygen. It was composed of carbon dioxide, water vapor, and nitrogen, with lesser amounts of carbon monoxide, hydrogen sulfide, and hydrogen cyanide. Because of these gases in the atmosphere, the sky was probably pinkish-orange. Meaning once earth obtained more oxygen the sky turned blue.

ale4655 [162]

Answer:

$P=750 e^{0.00963t}$

The population size would be 753,190 after 30 days

Explanation:

Since, the population growth function is,

$P = P_0 e^{rt}$

According to the question,

if t = 0, P = 750,

$\implies 750 = P_0 e^0\implies P_0 = 750$

Also, if t = 72, P = 1500,

$\implies 1500 = P_0 e^{72r}\implies 1500 = 750 e^{72r}\implies 2 = e^{72r}\implies \ln 2 = 72r\implies r = \frac{\ln 2}{72}\approx 0.00963$

Hence, the required function would be,

$P=750 e^{0.00963t}$

If t = 720 hours ( 30 days = 720 hours ),

Then, the population after 30 days would be,

$P=750 e^{0.00963\times 720}=750 e^{6.912}=753190.30695\approx 753190$

VLD [36.1K]

<h2>Answer:</h2>

AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.
