nHow would that temperature change affect the density of the air above the land or water being heated, and what direction would the air move?
Answer:
Water has a high specific heat, which means it absorbs more energy than air to raise its temperature

-QUESTION 6-
A population of coyotes lives in a habitat with plentiful food and no predators. Analyze the graph and interpret what is happening to their population size at the one year mark.
A.The population size is increasing
B.The population size is decreasing
C.The population size is remaining the same.
D.The population size cannot be inferred from the graph
Answer:
A. The population size is increasing
Explanation:
Looking at the graph upon the x-axis we see the blue line at an increasing direction to the right. That means the population is increasing at the 1 year mark.
In an ecosystem , where there are no predators which can prey upon coyotes and they have plentiful food their population size is expected to increase which can be inferred from the given graph.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Annual precipitation amounts in centimeters are shown in the table for four environments. Which environment experiences the least humidity? (2 points)
Environment A 80–120 cm
Environment B 20–50 cm
Environment C 150–200 cm
Environment D 40–60 cm
The environment that experiences the least humidity is Environment C 150–200 cm. The correct option is C.
What is humidity?Humidity is the presence of water vapor in the atmosphere. If the water vapor in the atmosphere is high, then the high is humidity, when the vapor in the atmosphere is low, it is called low humidity.
Precipitation is the presence of condensation in the atmosphere. It creates hail, snow, or haze. It happened due to the gravitational pull of the clouds.
Here, the humidity is given 150–200 cm. of the environment C. The higher the precipitation, the lower will be the humidity. When the rain is high, there will be more humidity due to water in the atmosphere. So, Annual precipitation will be higher.
Thus, the correct option is C. Environment C 150–200 cm.

Animal Reproduction Interactivity
Can you describe how an aquarium moon jellyfish population will change over time?
Record Data and Observations
Part 1 Explore the Life Cycle
For each transition in the jellyfish life cycle, indicate whether it is the result of growth, sexual reproduction, or asexual reproduction. Provide the evidence that supports your choice for each.
Adult medusas to larvae
Larva to polyp
Polyp to reproducing polyp
Reproducing polyp to juvenile medusas
Juvenile medusas to adult medusas
Analyze and Conclude
1. Draw Conclusions Once polyps have been established and are producing juvenile medusas, is sexual reproduction required to provide adult medusas for the exhibit? Explain why or why not.
2. Scientific Writing The museum has asked you to make a sign for the exhibit. Visitors will read the sign when guides and volunteers are not available to talk about the exhibit. Using the information gathered in this interactivity, write a paragraph that describes what visitors may see in the tank and explains the reproductive cycle of jellyfish.
Step 1
Jellyfish do not give birth to their young because they expel undeveloped eggs in the form of zygote or embryo from their bodies and deposit them on the ocean floor before moving on. They don't even care about the eggs that have been laid.
Step 2
Jellyfish have two distinct body types during their lives: medusa and polyps. Polyps reproduce by budding while medusa reproduce as by spawning eggs and sperm.
Jellyfish can reproduce in the adult, or medusa, stage by releasing sperm and eggs into the water, forming a planula. Polyps clone themselves and bud, or strobilate, into ephyra, a different stage of jellyfish life. The adult medusa jellyfish develops from his form.
Only a few jellyfish species obtain sperm through their mouths in order to fertilise eggs within their bodies, but the majority of jellyfish simply release sperm or eggs into the water. They will do this once a day, normally at dawn or dusk, if conditions are favorable.
