The red imported fire ant is an invasive species that has affected many native species in North America. Scientists wanted to see the effect of the fire ants on the survival of a certain kind of native bird. They treated nests of the bird with a chemical that kills the ants. They treated a different percentage of bird nests in different areas. In some areas, only 25% of the bird nests were treated with the chemical. In other areas, 100% of the bird nests were treated with the chemical.
The graph below shows the percent of birds surviving compared to the percentage of bird nests treated with the ant-killing chemical.
What conclusion about the effects of fire ants on the birds is best supported by the graph?
A.
The birds are more likely to survive when there are many fire ants, so the ants are likely outcompeting the birds for resources.
B.
The birds are more likely to survive when there are many fire ants, so the ants are likely providing resources for the birds.
C.
The birds are less likely to survive when there are many fire ants, so the ants are likely taking over the niche of the birds.
D.
The birds are less likely to survive when there are many fire ants, so the ants are likely predators of the birds.

The only statement which describes how jellyfish have a different adaptation to moving in the ocean than sharks and dolphins is:
Jellyfish fill the top part of their body with water and squeeze the water out to move.
What is adaptation?This is the ability of an organism to successfully adapt and survive in a particular environment.
Within the context of this medium, jellyfish bodies are:
Tansparent They have long tentaclesSo therefore, jellyfish fill the top part of their body with water and squeeze the water out to move.

Use the drop-down menus to complete each sentence about the layers of the atmosphere.
If the
did not exist, Earth might be destroyed by chunks of rock from space.
The
is located 12 to 50 kilometers from Earth’s surface.
Both the
get colder as altitude increases.
The ozone in the
protects people from ultraviolet (UV) radiation.
The
has the highest temperature of any layer in Earth’s atmosphere.
Answer:
Mesosphere
Stratosphere
Trophosphere and Mesosphere
Stratosphere
Thermosphere
Explanation:
The Stratosphere
This extends upwards from the tropopause to about 50 km. It contains much of the ozone in the atmosphere. The increase in temperature with height occurs because of absorption of ultraviolet (UV) radiation from the sun by this ozone.
Troposphere
Earth’s troposphere extends from Earth’s surface to, on average, about 12 kilometers (7.5 miles) in height.
Mesosphere
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
Thermosphere
Located between about 80 and 700 kilometers (50 and 440 miles) above Earth’s surface is the thermosphere, whose lowest part contains the ionosphere. In this layer, temperatures increase with altitude due to the very low density of molecules found here.

What happens when red blood cells decreases in the blood?
Answer:
Having a low level of red blood cells can diminish the ability of the blood to transport oxygen, which can cause the heart to come under strain as it works to get enough oxygen to the tissue. Anemia can happen with lower red blood cell count or when red blood cells dont contain enough hemoglobin.
Which contains alleles A and B in the same genotype what is this phenomenon called
Answer:
Codominance, in genetics, phenomenon in which two alleles (different versions of the same gene) are expressed to an equal degree within an organism. As a result, traits associated with each allele are displayed simultaneously. An example of codominance is seen in the MN blood group system of humans.
