Explanation:
Researchers studied a hardwood forest containing a variety of trees, other plant species, fungi, and animals. They measured the atmospheric carbon dioxide concentrations around the forest. The concentration was found to be lowest right next to the forest and steadily increased as the researchers measured farther away from the forest. How does this observation support the Law of Conservation of Mass?
A)The amount of carbon burned by fossil fuels decreases further away from the forest.
B)The carbon released by plants through photosynthesis is quickly cycled through the cellular respiration of animals.
C)The carbon released into the atmosphere by decaying organic matter increases as you move further away from the forest.
D)The carbon dioxide released by animals through cellular respiration is used by the trees to create food necessary for growth and maintenance.

What does a scientist need to know to figure out the relative age of a rock layer?
A. the age of the layers above and below the rock
B. the age of the fossils of the top layer
C. the rate of decay for all elements in the rock
D. the radioactive element in the rock
The rate of decay C
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Answer:
A is the answer, this is because deposition has been happening on earth for ages so as time goes by more deposits form layers on earth, including the remains of animals and plants that would later become fossils.
Do other organisms get any benefit from a cicada’s life cycle?
Answer:
Cicadas are mostly beneficial. They prune mature trees, aerate the soil, and once they die, their bodies serve as an important source of nitrogen for growing trees. When cicadas come out, they're eaten by just about anything with an insectivorous diet.
After the long 2 to 17 years, cicadas emerge from the ground as nymphs. Nymphs climb the nearest available vertical surface (usually a plant) and begin to shed their nymph exoskeleton. Free of their old skin, their wings will inflate with fluid (hemolymph) and their adult skin will harden (sclerotize).
Should I kill cicadas? While it can be tempting to use pesticides on cicadas, there's really no need. “Treating yards to kill cicadas will result in an unnecessary application of pesticides to the environment and treating these insects directly may also sicken animals who then try to eat them,” Troyano says.
Basically Cicada's feed off of plants while people and animals eat the cicadas... Hope this helps
Explanation:
Answer:
Yes, I think other organisms benefit from a cicada's life cycle. When they come out of the ground and make a run for the trees, many of them become a meal for lots of different creatures, like birds, squirrels, coyotes, and deer. They have a lot of protein to help these animals survive.

List 3 negative impacts does plastic pollution have on the ocean?
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

Muscle is soft tissue. Many elastic fibers make up the muscles. The body has over 600 muscles. Different muscle types have different tasks. Some muscles help you run, jump, and perform delicate tasks like threading a needle. Other muscles enable breathing and food digestion. Your heart is a hard working muscle that beats thousands of times a day. There are three types of muscle tissue in the body. They are:
Skeleton: As part of the musculoskeletal system, these muscles work in concert with bones, tendons and ligaments. Tendons attach skeletal muscles throughout the body to bones. Together they support the weight of the body and aid movement.
You control these voluntary muscles. Some muscle fibers contract rapidly, expending short bursts of energy (fast-twitch). Others move slowly like this: B. Back muscles that help with posture.
Heart: These muscles line the walls of the heart. They help the heart pump blood through the cardiovascular system. They do not control the heart muscle. Your heart tells them when to contract.
Smooth: These muscles line organs such as the bladder, stomach, and intestines. Smooth muscle plays an important role in many body systems, including the female reproductive system, the male reproductive system, the urinary system, and the respiratory system.
These muscle types work without you thinking. They perform important tasks such as moving waste products through the intestines and helping the lungs expand when breathing.

What kind of texture would an igneous rock that formed deep underground have?
completely smooth
coarse-grained
fine-grained
grains of many different sizes
Answer:
coarse-grained
Explanation:
Intrusive rocks have a coarse grained texture. Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface. These are the rocks that form at erupting volcanoes and oozing fissures.
How is it that a parent can give an allele not to show up in the phenotype
Answer:
Explanation:
n other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous ("hetero" meaning "different") for that allele. ... The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

What conclusion can be drawn about the number of elements the make up the majority of the world in which we live and the total number of elements identified on the Periodic table?
Answer:
I think what you're reaching for is how the vast majority of the world we live in is comprised of only a few elements on the periodic table (carbon, hydrogen, oxygen, to name a few).
Explanation:
The other molecules identified on the periodic table do exist in nature but in much smaller quantities than those of a select few atoms.
Answer:
Of these 118 elements, 94 occur naturally on Earth. Six of these occur in extreme trace quantities: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; and plutonium, number 94.

HOW DOES STRESS AFFECT YOUR FOCUS???
Hint: The shallower our breath, the less oxygen that reaches our brain, and the harder it is to focus.
1: When you are stressed you start breathing more deeply and makes it harder to focus.
2: When you are stressed more oxygen gets to your brain and makes it harder to focus.
3. When you are stressed you start breathing more deeply and that delivers more oxygen to your brain helps you focus.
4. none of these
Answer:
Ironically, stress does improve concentration for a very short period of time. This is due to the body releasing chemicals into the brain to help it focus and pushing adrenaline into the bloodstream in order to heighten the senses, which helps the body hone in and focus on tasks at hand.
