pls mark brainliest
Explanation:
Carmen plays basketball, the energy she needs originally came from other sources. Chemical energy is transformed into kinetic and thermal energy in her body. This sentence is not true about this scenario.
Thermal energy ?The energy present in a system that determines its temperature is referred to as thermal energy. Thermal energy flows as heat. Thermodynamics is a whole branch of physics that studies how heat is transmitted across various systems.
Fossil fuels like natural gas, coal, and oil are examples of thermal energy sources. They also include solar heat, electric heat pumps, and geothermal heat.
Conduction, radiation, and convection are the three different ways that thermal energy is transferred. Only fluids experience the cyclical process of convection.
Thermal energy is the total kinetic energy of all moving particles of matter. Thermal energy exists in a variety of substances, besides merely hot ones like the sand and air of Death Valley. Even material that feels cold possesses thermal energy.
Thus, option C is correct.

A.Most of the newts had low-poison level traits; very few had high-poison level traits.
B.Most of the newts had high-poison level traits; very few had low-poison level traits.
C.All of the individuals in the population had high-poison-level traits.
D.None of the individuals in the population had high-poison level traits.
2.
Which description matches the histogram of the population today?
A.Most of the newts have low-poison level traits; very few have high-poison level traits.
B.Most of the newts have high-poison level traits; very few have low-poison level traits.
C.All of the individuals in the population have high-poison level traits
D.None of the individuals in the population have high-poison level traits
Answer:
B for the first answer
Explanation:
The histogram of the population 50 generations ago showed that the majority of newts had low-poison level traits and very few had high-poison level traits. Now, the histogram of the population shows that the majority of newts have high-poison level traits and very few have low-poison level traits. So, the correct option for 1 and 2 are A and B.
What is Histogram?A histogram is a graphic depiction of a frequency distribution with continuous classes that has been grouped. A series of rectangles with bases equal to the distances between class boundaries and areas proportional to frequencies in the associated classes make up the area diagram.
Since the base in such representations spans the spaces between class boundaries, every rectangle is neighboring. For above given example, The population's histogram from 50 generations ago revealed that most newts possessed low-poison level features, while just a small number possessed high-poison level traits. Now, the population's histogram reveals that most newts exhibit features associated with high poison levels, whereas relatively few exhibit traits associated with low poison levels.
So, the correct option for 1 and 2 are A and B.

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.

had not changed.
B.The population size stopped increasing because it had reached
the largest number of coyotes that the ecosystem could support.
C.The populations size became zero because the ecosystem could
no longer support the coyote population.
D.The population size can no longer be inferred from the graph
once carrying capacity is reached.
Answer:
b
Explanation:
In an ecosystem ,when the coyote population reached its carrying capacity, it's population stopped increasing because it had reached the largest number of coyotes that the ecosystem could support.
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.

Question 3 (please help)
When a population grows past the ecosystems carrying capacity, what happens to the population?
A.Continues to grow
B. The population starts to die off
C.The population grows then finds a new carrying capacity
Answer:
the Answer is B
Explanation:
If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size. Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species.

What are some possible ways these rocks were formed? Be sure to discuss all 3 rocks.
pls help me
Answer:
1 Sedimentary 2. Metamorphic 3. Igneous (look down for how they are formed)
Explanation:
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
