Answer:
A) contains more carbon dioxide than the air you breathe in
Explanation:
So based on our basic knowledge, we know that we breathe in air, keep the oxygen, and breathe out everything else plus the carbon dioxide we make in our lungs. So A is really the only one that makes sense.

In the experiment, how could recover the dissolved salt? How do you think its mass would compare with the mass of dry salt you started with.
ALSO I HAVE NO IDEA EVEN GUESSES WOULD BE HELPFUL
Answer:
You can recover the dissolved salt by heating the water. When heated the water will evaporate, and the salt will be left. It's mass would be the same as at the beginning.

and a sperm cell have only half the normal
number of chromosomes.
Answer:
Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells

One hot summer day Thomas left a glass of full of water outside when he went back to get it the next day half of the water was gone what type of interaction with the Earth system was this
A.Lithosphere-Biosphere
B.Hydrosphere-Atmosphere
Answer:
B
Explanation:
Hydrosphere-AtmosphereB. Hydrosphere-Atmosphere
The hydrosphere comprises the totality of Earth's water. The atmosphere comprises the totality of Earth's air. The liquid water in the glass that was left outside evaporated, turning into gaseous water vapor that escaped the glass. The water as a liquid in the glass and as a vapor as a gas are both part of the hydrosphere. But once some of the liquid water became gaseous water vapor, that water became part of the Earth's atmosphere.

Describe how the relative surface temperature and the relative luminosity of Aldebaran would change if it collapses and becomes a white dwarf like Procyon B
Answer:
Greatly affect the luminous intensity.
Explanation:
The relative surface temperature and the relative luminosity of Aldebaran will greatly decreases if it becomes Procyon B because more surface area of a star increases the luminous intensity of that star. The size of Aldebaran is 30.7 million km whereas the size of Procyon B has 8585 km which very much lower than the Aldebaran so there is a great difference in the magnitude of luminosity between Aldebaran and Procyon B. So we can conclude that the decrease in the surface area of a star will greatly affect its luminous intensity.

What type of carbon-based molecule is the first to be broken down by the body's cells to provide a source of energy?
Answer: Glucose
Explanation:
The carbon based molecule which is broken by the cells of the body is glucose it is a carbohydrate that is obtained from food we consume it is stored in the form of glycogen. When the energy requirement of the body increases then glucose monomers are released from the glycogen chain so that glucose monomers can participate in the energy generation process in the mitochondria of the cell. The chemical energy so produced is ATP (adenosine triphosphate).
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.

B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.

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.
