The messages that scientists are sending into space are directed at intelligent alien life. Do
you think this is limiting? How could this affect scientists search for life beyond Earth?
Answer:
I think there is life beyond earth. Actually there most definently is. I think in a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?

Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.
What is a tundra?The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.
Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.
Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.
Therefore, option (D) is correct.

When population grows past the ecosystem’s carrying capacity, what happens to the population?
A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.
Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to use
When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).
The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

why are there no gram-positive archaea species but there are gram-positive bacteria species
Answer:
There are no gram-positive archaea because archaea lack peptidoglycan in their cell walls, meaning that the archaic cell walls are more similar to gram-negative bacterial walls, although they do show a greater variety of cell wall types. And bacteria do have this.
what forces cause surface ocean circulation? what forces cause deep water circulation?
Answer:
ANS 1) Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.
ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). There is often confusion over the components of the circulation that are wind and density driven.

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?
Answer:
40% increase
Explanation:
Percentage Increase Formula:
Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%
To Calculate Percentage Increase:
1) Subtract final value (later value) minus starting value (initial value)
2) Divide that amount by the absolute value of the starting value (initial value)
3) Multiply by 100 to get percent increase
Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.
So for your problem,
[(420-300)/300]*100% = 40% increase
