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?

Answers

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?

Answers

Answer:

share a common ancestor

Explanation:

The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.

Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.

Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their differences as they currently exist.

How do wetlands form?

Tributaries flow into rivers.
Runoff travels down the side of a divide.
Water builds up in a depression left by an ice sheet.
Groundwater comes to the surface and floods the land.

Answers

Answer:

D) groundwater comes to the surface and floods the land

Explanation:

Groundwater like water from river or lake comes to a land and before it has a chance to go back into the soil or evaporate, more water comes and floods the areas, thus the previous water stays and new water stays as well. If this cycle is repeated, a wetland will form.

wetlands form The tributaries flow into rivers.

How do wetlands form?

Wetlands is a flat area of abundant herbaceous and/or shrubby vegetation that remains flooded most of the time. Swamps generally appear in areas where water flow is slow. In this way, the organic mass present in the waters decomposes on the spot.

With this information, we can conclude that wetlands are formed. The tributaries flow into rivers.

Which of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?
A : Nutrients are absorbed into the blood from the intestines.
B : Lungs expand and contract through movements of the diaphragm.
C : New red blood cells are generated in the marrow of bones.
D : Gases exchanged in the lungs are carried by the blood.

Answers

Answer:

Explanation:

Your first order of business should always be to see which answers involve both of the systems. A has the circulatory system (blood) but no respiratory system (intestines are the gastrointestinal system), B has the respiratory system (the lungs) but no circulatory system, C has the circulatory system (new red blood cells) but not the respiratory system (bones are the skeleton), and that just leaves D, so it has to be the answer. When you look at it to check, it includes both systems, as the lungs are part of the respiratory system and the blood is part of the circulatory system.

Describe how changing a biotic or abiotic factor can influence an entire biome. Could changing biotic or abiotic factors be responsible for the decrease in phytoplankton populations introduced at the beginning of this lesson? Explain.

Answers

Answer:

it can change weather things will live or die

Ecological succession occurs when changes to either abiotic or biotic factors have an impact on an entire ecosystem. The replacement of one community of creatures, such as a plant or animal, by another is known as ecological succession. A forest fire is one illustration.

What biotic or abiotic factor can influence an entire biome?

An ecosystem's overall health is also influenced by biotic factors such as the diversity of consumers and the presence of autotrophs, or self-sustaining organisms like plants.

Abiotic variables have an impact on an organism's capacity for survival and reproduction. Populations are constrained in their expansion by abiotic forces. In an ecosystem, how these elements interact is crucial.

Therefore, it can change weather things will live or die.
