Hope it’s usefullll
In this activity, you will use presentation software to create a presentation of 15 to 20 slides explaining your arguments in support of or against the following statements:AIDS continues to be a global health crisis. AIDS still meets the definition of a pandemic.
Your claims should be supported by scientifically complete evidence. Follow the steps provided to research, plan, and create your presentation. This guide about the research process can help.
Time to complete: 2 to 3 hours
Part A: Ask Questions Begin by creating a list of questions to guide your research and help you form a convincing argument. Your presentation should answer some of these questions: What is the definition of a pandemic? How does a pandemic differ from an endemic or epidemic? What is the life cycle of the HIV virus once it enters the body? How does the genetic code of the virus change? How does HIV affect the body? How do people become infected with HIV? How does AIDS develop from an HIV infection? What are the current infection rates of HIV across the globe? Where is HIV/AIDS most prevalent? What treatments are currently available for HIV/AIDS? Do some regions of the world have better access to treatments than others? What is the average life expectancy for someone with HIV? Does life expectancy differ around the globe? Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation.
Based on the information given, a pandemic simply means the spread of an infectiousdisease.
What is HIV?
It should be noted that the difference between an epidemic and a pandemic is the degree if its spread.
HIV is simply a virus that attacks the immune system. It can be gotten through unprotected intercourse, sharing sharp objects, etc. It should be noted that in the long run, HIV leads to AIDS.
It should be noted that HIV is most prevalent in Sub Saharan Africa. There are presently no cure for HIV but there are medications to control the complications.
The average life expectancy for someone with HIV is 56 years.
This example of sedimentary rock is formed when rock fragments, minerals, and the remains of plants and animals are deposited as sediments and are thenA) chemically weathered by water. B) compacted and cemented together. C) recrystalized under the weight of the layers. D) melted due to increased temperature and pressure.
B) compacted and cemented together
Answer: B) compacted and cemented together
1. Which is NOT an energy type? A. non-renewable B. valuable C. renewable
non renewable: oil
hope i could help
valuable is not an energy type
17. Which of the following statements is/are correct? A. Leeches are members of the phylum Platyhelminthes B. All platyhelminthes are parasites of other organisms. C. Most, if not all, Platyhelminthes lack a coelom. D. Given the following on the organism: I. An animal II. Multicellular III. has tissues (diploblastic) IV. Lacks a digestive tract V. is asymmetrical This organism could be a member of the Phylum Platyhelminthes E. Platyhelminthes can not reproduce sexually
The options B, C, D and E are correct
B. More of organisms in the phylum platyhelminthes are parasitic in nature.
C. Platyhelminthes are acoelomates and therefore lacks coelom.
D. Phylum Platyhelminthes organisms are multicellular, asymmetrical, lack a digestive tract and are advanced diploblastic.
E. Most Platyhelminthes are hermaphrodites possessing the male and female sex organs.
Option A is wrong because:
A. Leeches are in the Phylum Annelida and are segmented in nature.
They are advanced
As a result of this characteristic, they are able to reproduce asexually and sexually
Which statements help explain how Earth formed as part of the solar system? Select the two correct answers. (1 point)-The denser rocky material in the solar nebula stayed closer to the sun. -Gaseous planets slowly changed to rocky planets after colliding with meteorites. -Water and ammonia condensed from gases to ice particles. -Very large asteroids broke apart to form rocky planets, including Earth. -The accretion of cosmic dust formed the seeds of planets, including Earth
The statements 'the accretion of cosmic dust formed the seeds of planets' and 'the denser rocky material in the solar nebula stayed closer to the sun' help explain how Earth formed. It is part of the solar system.
The solar system
The solar system consists of the Sun and eight planets (i.e., Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune).
The solar system is also composed of Pluto (a dwarf planet) many different moons, asteroids, etc.
The solar system formed approximately 4.6 billion years ago from interstellar gas and dust.
