Answer:
Viruses are tinier than bacteria. All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells.
Explanation:
In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.
The first option is correct.
Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.
The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Happy homework/ study/ exam!
Answer:
Ganymede has a very thin atmosphere and its average surface temperature is -171 degrees F. so it would obviously require an external suit for protection from the elements and to store, filter and convert oxygen to a form breathable by humans, as Ganymede has a largely oxygen composed atmosphere but not in the form or density humans need. For a size comparison, here is a picture of Earth, our moon and Ganymede all side by side. Ganymede is the medium sized of the three in the bottom left-hand corner.
It has a liquid-iron core which provides a small magnetosphere for protection from radiation but Jupiter’s magnetosphere substantially over powers it. The surface gravity is slightly more than a tenth of Earth’s, so I’d personally enjoy the lesser effort required to move my big bones around. As with most moons, Ganymede is tidally-locked, meaning that one side always faces Jupiter and one side always faces outward. This means a few things but most importantly to your question, it means that Jupiter’s gravity pulls hard enough, continuously on the same side to provide some geothermal activity. Those warm spots would provide opportunities for energy gathering and further scientific study.
Maybe the most important part of Ganymede’s potential habitability is that we believe it has a huge underground salt-water ocean which could be used in many ways to sustain a colony. The only obstacle is that much and/or all of the technology we are talking about that would be required, is not yet in existence.
Answers: option b. supplements
Explanation:
Supplements are only needed when you have a special defficiencies on your intake of nutrients on as consequence of an organic disorder.
Healthy athletes who are on a balanced diet are already having all the vital nutrients, needed from their diet.
Athletes with intense activity do need vitamins, carbohydrates and fats which are on the regular diet: fruits, vegetables, carbohydrates and fats. Eating healthy provide you the nutrients your organism needs to obtain energy and create the muscles to perform well as athlete.
