Answer:
Animals in space originally served to test the survivability of spaceflight, before human spaceflights were attempted. Later, other animals were flown to investigate various biological processes and the effects microgravity and space flight might have on them. Bioastronautics is an area of bioengineering research which spans the study and support of life in space.
Explanation:
Example 1: Albert II became the first monkey in space on June 4, 1949. He reached an altitude of 83 miles (134 km), but died on impact when the parachute failed. A previous monkey, Albert I, died when the V-2 rocket failed before reaching peak altitude. Two other monkeys, Albert III and IV, also died when their rockets failed.
Example 2:A mouse launched on Aug. 15, 1950, attained an altitude of 85 miles (137 km), but died when the rocket disintegrated due to parachute failure. Several other mice were launched during the 1950s.
Example 3 (and the most important example): Laika became the first living being to orbit the Earth on Sputnik 2, Nov. 3, 1957. She died several hours into the flight from stress and heat.

Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere
Answer:
Ocean plays the role of regulator.
Explanation:
The role of the ocean change with respect to the amount of carbon dioxide in the atmosphere because oceans plays a role of regulator and balancer. When there is high amount of carbon dioxide in the atmosphere due to burning of fossil fuels and volcanic eruptions so the ocean absorb that extra amount of carbon dioxide from the atmosphere while on the other hand, when there is decrease in the concentration of carbon dioxide in the atmosphere, the ocean gives its carbondioxide gas to the atmosphere to regulate the concentration.

Energy and matter cycle through a beach on the ecosystem on the gulf of mexico identify one kind of model you can use to show the path of energy and matter through this ecosystem
Hello. This question is incomplete. The full question is:
Energy and matter cycle through a beach ecosystem on the Gulf of Mexico. Identify one kind of model you can use to show the path of energy and matter through this ecosystem. Describe one benefit of using that kind of model to show those processes.
Food web; shows energy available at each trophic level for the next group of organisms
Energy pyramid; show all pathways of energy flow in an ecosystem
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Answer:
Food chain; shows a single pathway of energy flowing, making it easy to see which organisms are primary, secondary and tertiary consumers
Explanation:
The food chain represents a linear sequence of energy transfer within an environment. This transfer is carried out with a sequence of living beings that serve as food for each other and this food that promotes the transfer of energy through a single path, allowing all levels of transmission to be observed, through primary, secondary and tertiary.

Which of the following best describes the matter present in an ecosystem?
A.
New matter is continuously generated by an ecosystem in a process known as photosynthesis.
B.
The waste materials generated by one organism are often reused by other organisms.
C.
The total amount of matter in an ecosystem is constantly decreasing due to the process of decomposition.
D.
When an organism reproduces, new matter is added to its ecosystem.
Answer:
D
Explanation:
When an organism reproduces, new matter is added to its ecosystem, is the correct answer.
Answer: It's is the second one. The waste materials generated by one organism are often reused by other organisms.
Explanation: Mass, or matter, is conserved in all physical and chemical changes. Matter is not created or destroyed within ecosystems, it only undergoes physical or chemical changes. One example of this process is that the waste materials generated by one organism are often reused by other organisms as food or nutrients.

HOW DO BONES WORK?
Answer: Although they're very light, bones are strong enough to support our entire weight. Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.

3.- Cuáles son los parámetros para la valoración de los efectos producidos por los impactos ambientales
Answer:
Los parámetros son: magnitud, extensión, persistencia, reversibilidad, recuperación, persistencia, sinergia, probabilidad de ocurrencia, relación causa y efecto
Explanation:
La evaluación de un impacto ambiental debe tener en cuenta los siguientes parámetros principales:
- Magnitud. La magnitud se refiere al hecho que un impacto ambiental puede afectar al ecosistema en diferentes niveles.
- Extensión. Este término se refiere a la superficie (por ejemplo, en metros cuadrados) del ecosistema el cual ha sufrido el impacto.
-Reversibilidad. La reversibilidad indica la probabilidad de que el ecosistema una vez que ha sufrido el impacto pueda regresar a su estado inicial.
- Recuperación. La recuperación es el grado de restauración al que puede llegar el medioambiente una vez sufrido el impacto.
- Persistencia. La persistencia indica la duración (cuantificable en tiempo) del impacto ambiental.
- Sinergia. La sinergia se refiere al hecho de que dos o más impactos ambientales poseen un efecto mayor sobre el ecosistema que el producido mediante varios impactos ambientales por separado.
- Probabilidad de ocurrencia. La probabilidad de ocurrencia expresa la posibilidad de que un impacto ambiental se produzca en un ecosistema durante un determinado período de tiempo.
- Relación causa y efecto. La relación causa y efecto clasifica a los impactos ambientales en directos (causados por el impacto) e indirectos (causados por las consecuencias derivadas del impacto).
