Lactic acid fermentation and alcoholic fermentation
Answer:
A pandemic is an epidemic disease extended across wide regions, thereby affecting many countries and even continents, while endemic diseases affect the people from only one country or a specific region. Human Immune Deficiency (HIV) is an RNA virus whose life cycle is composed of the following stages: 1) binding to the cell host and membrane fusion, 2) subsequent reverse transcription into DNA and integration into genome host 3) proliferation (i.e., successive replication cycles) by using the cellular machinery of the host 4) new assembly and budding of the virus. The acquired immune deficiency syndrome (HIV/AIDS) occurs when the host immune system is seriously damaged by the HIV infection, this being the latest stage of infection. It is known that HIV/AIDS is more prevalent in the female population, while according to ethnic groups, it is more prevalent in African-American and Hispanic/Latino populations in the USA. The life expectancy in HIV-infected patients has notably improved in the last years and, currently, people with this disease can expect to live over 70 years or even more.
Advantages of asexual reproduction:
- There is no need for a mate/ only one parent is required
- It takes less time compared to sexual reproduction
Disadvantages of asexual reproduction:
- There is little genetic variation/less diverse population
- Offspring cannot adapt to change
Advantages of sexual reproduction:
- Genetic diversity
- Offspring can adapt to change
Disadvantages of sexual reproduction:
- Two parents are needed
- Slow reproduction compared to asexual reproduction

Answer:
Yes, Mass Extinctions May Have Been Caused By Meteors, as the probability of mass extinction occurring after an asteroid that could hit a random location on the Earth's surface was approximately 13% when the Chicxulub-scale asteroid hit the Earth.
Soot could be the main cause of mass extinction after an asteroid impact.
