Goats are outside living on the sides of steep mountains. They are eating the
grass and bushes that grow there. It's a clear, sunny day on the mountainside.
What is happening to the carbon dioxide in the air? Is it ONLY being released (as a
product), ONLY absorbed (as a reactant), or being released AND absorbed?
CO2 is being both released by goats in exchange for O2 and absorbed by the plants in exchange for O2, too
Why is Gene Therapy considered an effective (helpful) method to treat genetic disorders?

gene
B) It increases the likelihood (chance) of passing genetic mutations to offspring
C) It replicates resistance genes in the cells of unhealthy individuals
D) It replaces a defective gene with a healthy gene
Answer:
D) It replaces a defective gene with a healthy gene
Explanation:
Gene therapy is the process of replacing defective genes with healthy ... genes to help the body fight or treat disease, or deactivating problem genes.
how would the solar eclipse be different if the moon was moved AWAY from the earth?
Answer:
The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

Why are humans dependent on healthy ecosystems throughout the world?
Answer: Human health ultimately depends upon ecosystem products and services (such as availability of fresh water, food and fuel sources) which are requisite for good human health and productive livelihoods. Significant direct human health impacts can occur if ecosystem services are no longer adequate to meet social needs.
Explanation:
Humans are dependent on healthy ecosystems as they provide resources, regulate climate, purify water, control diseases, offer recreational and cultural values, and drive economic activities.
For a number of reasons, functioning ecosystems are essential to human existence. supplying resources Healthy ecosystems offer vital resources like food, fresh water, clean air, and building supplies like fibre and wood. These materials provide for our basic necessities and are essential to our survival. Genetic and biological diversity: Numerous plant and animal species are supported by ecosystems, which increase biodiversity. Ecosystem stability is ensured by biodiversity, which also increases resilience to environmental changes and offers genetic diversity. The creation of novel foods, medicines, and other useful goods depends on this diversity.

Explanation:
A heater provides heat to an area, but the temperature in the area stays about the same. What do you already know about this phenomena?
ANSWER: IT'S CALLED THE ZEROTH LAW OF THERMODYNAMICS
EXPLANATION:
The zeroth law of thermodynamics state that there's no heat transferred between two objects in thermal equilibrium (i.e having the same temperature). This phenomenon depicts that there's balance in the amount of temperature in all the three entities.
This phenomenon was credited to Sir Ralph Howard Fowler, a British physicist and astronomer during his lifetime.
A scientific paper by Carathéodory also added that when two systems S1 and S2 are made to reach equilibrium with a third system S3 under close thermal conditions, systems S1 and S2 are said to be in mutual equilibrium.

How does air pressure affect
breathing?
Answer:
When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.
Answer:
The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate. This is because air moves from high pressure areas to low pressure areas. During bad weather and at high altitudes the air pressure is lower, making it harder for us to breathe.

Nucleus - controls cell activities, contains the DNA for the cell.
Cytoplasm - supports and protects all cellular organelles.
Endoplasmic Reticulum - aids in making proteins, carries materials through the cell.
Ribosome - synthesizes proteins.
Mitochondria - breaks down sugar molecules to release energy, site of aerobic cellular respiration.
Golgi Complex - modifies proteins made by the cell, package and export proteins.
Vacuole - store food, water, metabolic, and toxic waste.
Lysosome - break down old cell parts, break down larger food molecules into smaller pieces.

Phosphorus in soil is transformed into insoluble compounds unless what happens?
Answer:
It is not absorb by the plants, it turns into insoluble form.
Explanation:
Phosphorus in soil is transformed into insoluble compounds unless not used by the plants. The insoluble phosphorus is transform into soluble form in the soil by phosphorus solubilizing bacteria. The phosphorus solubilizing bacteria helps in conversion of insoluble phosphorus into soluble phosphorus which can absorb by the plants. If the phosphorus is not absorb by the plants and present for a long time, it can be converted into insoluble form which is unavailable for the plants which can be converted back with the help of phosphorus solubilizing bacteria.

Stomata regulate transpiration and CO2 intake by changing its size depending on the environmental signals. In optimum conditions, stomata are wide open, allowing gaseous exchange with the atmosphere.
Imagine that you are hiking and discover an outcrop of sedimentary rock. The rock is arranged in three distinct layers that appear to be undisturbed. When you examine the layers more closely, you observe fossils in the bottom and middle layers. What inferences can you make about these fossils based upon your observations and your knowledge of the law of superposition?
Answer:
The age of fossils are in millions.
Explanation:
These fossils were present on the earth millions of years ago due to different and unique structure of the fossil. The fossil is present in the bottom of the middle layer indicates that the more age of fossil i.e. millions of years according to the law of superposition. This law states that in an undisturbed layers of rocks, the top layer is the younger layer than middle and bottom layers which is older than the top layer, so we can say that fossils from deeper layers are older than fossils from the top layers of rocks.
What is the difference between natural selection and selective breeding? Then, give examples of natural selection and selective breeding?
Natural Selection is when traits are "naturally" selected for, because "survival of the fitttest." Example would be a species becoming bigger over time, because the smaller animals of that species were more likely to be eaten by predators. Natural selection is when the "best" trats are passed down due to chance
Selective breeding is if an outside forece (like a dog breeder) "chooses" a triat to be passed down. Example, instead of breeding a brown dog with a white dog, the breeder breeds two black dogs together in orer for the litter to all have black fur

Radiation is a method of thermal energy transfer that moves-
Helppplp plss I’ll choose as brainliest
Answer:
-heat
Explanation:
Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.
Good luck!!
Answer:
Explanation:
Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .
