Answer:
nitrogen fixers------cyanobacteria
jellyfish--------------- nekton
zooplankton ----- phytoplankton
whales----------- nekton
Explanation:
Diatoms are single-celled algae that live in houses made of glass. They are the only organism on the planet with cell walls composed of transparent, opaline silica. Cyanobacteria is also called nitrogen fixers because cyanobacteria fixes atmospheric nitrogen in the soil in the available forms of nitrogen to the plants. Whales and jellyfish are nekton because they move in the water independently. Zooplankton feed on phytoplankton for gaining energy and survival.

Some animals have an organ called the gizzard. The gizzard is muscular and helps to crush up hard food. Earthworms and many birds, including chickens, have gizzards. Chickens swallow small rocks that help the gizzard to grind up food. Did plant-eating dinosaurs have gizzards too? No one has found an actual dinosaur gizzard, but they have found small piles of round rocks inside dinosaurs’ ribcages.
Based on its function, the gizzard is part of the

In what ways do humans rely on healthy ecosystems? Use the words "Natural Resources" and "Ecosystem Services" in your answer.
How does the loss of biodiversity impact ecosystem health?
Explain the main causes of biodiversity loss.
Answer:
Due to needs of resources.
Explanation:
Humans rely on healthy ecosystems because human needs resources such as food, clean water, disease regulation and climate regulation etc which can be provided by the ecosystem. If the ecosystem is healthy, human can harvest or get more resources from the ecosystem. The biodiversity present in the ecosystem makes the ecosystem healthy and is responsible for the presence of more resources so loss of biodiversity greatly impact ecosystem health. Climate change, pollution, destruction of habitats and invasive species are the main causes of loss of biodiversity in the ecosystem.
A laboratory investigation examined the growth rate of fruit flies in culture jars over time. The fruit flies were grown in an artificial
medium containing nutrients and moisture. They were enclosed in a culture jar of a defined size. Initially, there were ten fruit flies
in the experiment. The population reached 75 over the course of four weeks. However, after eight weeks, the population size
leveled off and then decreased. Survival of fruit fly larvae declined after eight weeks. Which hypotheses are supported by the
information in this scenario? Select ALL that apply?
A)

B)
The carrying capacity was exceeded by the fly population
Food was abundant for the first four weeks of the experiment.
D)
The fruit flies were unable to survive in a laboratory setting
E)
The carrying capacity decreased when no new food was added to the
culture jars.
Answer: B, D, E
Explanation:
USA test prep said it
The carrying capacity was exceeded by the fly population as Food was abundant for the first four weeks of the experiment.The fruit flies were unable to survive in a laboratory setting. The carrying capacity decreased when no new food was added to the culture jars. Options B,D and E are correct.
What is the reason of choosing fruit flies ?
The reason of choosing fruit flies is because of their big growth rate along with the smaller life cycle.
The carrying capacity that is the fruit flies were able to multiply faster and faster because the food source that is the nutrition that was given to the flies was in big amount thus the cycle could continue.
Fruit flies are able to reach a limit of the growth rate when they are in natural habitat when they reach the artificial setting then they are not able to get into the same growth rate.
The carrying capacity decreased when no new food was added to the
culture jars. With time when the nutrition source that was being added to the jars got decreased the flies stopped growth rate and reached a declining number as well.

2. Energy flows through Earth's spheres and changes along the way. Describe how energy is conserved in these systems. (2 points)
Answer:
Teaching about energy and physical processes is supported by 7 key concepts:
2.1 Earth is constantly changing as energy flows through the system. Geologic, fossil, and ice records provide evidence of significant changes throughout Earth's history. These changes are always associated with changes in the flow of energy through the Earth system. Both living and non- living processes have contributed to this change.
2.2 Sunlight, gravitational potential, decay of radioactive isotopes, and rotation of the Earth are the major sources of energy driving physical processes on Earth. Sunlight is a source external to Earth, while radioactive isotopes and gravitational potential, with the exception of tidal energy, are internal. Radioactive isotopes and gravity work together to produce geothermal energy beneath Earth's surface. Earth's rotation influences global flow of air and water.
2.3 Earth's weather and climate are mostly driven by energy from the Sun. For example, unequal warming of Earth's surface and atmosphere by the Sun drives convection within the atmosphere, producing winds, and influencing ocean currents.
2.4 Water plays a major role in the storage and transfer of energy in the Earth system. The major role water plays is a result of water's prevalence, high heat capacity, and the fact that phase changes of water occur regularly on Earth. The Sun provides the energy that drives the water cycle on Earth.
2.5 Movement of matter between reservoirs is driven by Earth's internal and external sources of energy. These movements are often accompanied by a change in the physical and chemical properties of the matter. Carbon, for example, occurs in carbonate rocks such as limestone, in the atmosphere as carbon dioxide gas, in water as dissolved carbon dioxide, and in all organisms as complex molecules that control the chemistry of life. Energy drives the flow of carbon between these different reservoirs.
2.6 Greenhouse gases affect energy flow through the Earth system. Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of Earth. These gases play a major role in determining average global surface temperatures. When Earth emits the same amount of energy as it absorbs, its average temperature remains stable.
2.7 The effects of changes in Earth's energy system are often not immediately apparent. Responses to changes in Earth's energy system, input versus output, are often only noticeable over the course of months, years, or even decades.
What characteristic of double-stranded DNA determines the ability of one strand to make an exact copy of the other strand?
O complementary pairing of bases
O hydrogen bonding between strands
O ability of bases to be connected in any order
O location of the base pairs in the center of helix
Answer:
The correct answer is ''complementary pairing of bases''
Explanation:
The double-stranded DNA with the complementary nitrogenous bases that are located inwards and establish non-covalent bonds (or attractive forces) to each other that maintain the structure of the molecule. Deoxyriboses (sugars) and phosphate groups constitute the columns of the molecule. When the cell divides, each new cell that is formed must carry all the genetic information that determines its characteristics and functions. For that, before dividing, DNA must replicate, that is, generate a copy of itself. During replication, the DNA molecule unwinds, separating its chains. Each of these will serve as a template for the synthesis of new DNA strands. The double-stranded DNA structure proposed by Watson and Crick (1953) suggested several important properties of the hereditary material: Complementarity rules of the nitrogenous bases A-T and G-C suggest a simple way of replication of the hereditary material. This simple form of replication is called a semi-conservative method. When DNA replicates, its two helices separate and each one of them serves as a template to synthesize a new helix following the pairing rules of nitrogenous bases.

why do organisms look the way they do? this assignment is due tonight:(
Answer:
They have different inherent information. Their environment also plays a role. But in sexual reproduction, it is based on the parents, with each contributing half of the genes aquired by the offspring.
Organisms look the way they do due to a combination of genetics, environmental factors, and natural selection.
What is genetics, environmental factors and natural selection?Genetics plays a significant role in determining an organism's physical characteristics, as genes provide the instructions for the development of traits such as eye color, hair texture, and height. Genetic variation within a population can lead to differences in physical appearance between individuals.Environmental factors, such as nutrition, exposure to sunlight, and exposure to pollutants, can also impact an organism's physical appearance. Natural selection also plays a role in determining an organism's physical appearance. Individuals with traits that help them to survive and reproduce in a given environment are more likely to pass on those traits to their offspring.Ultimately, the way an organism looks and reflects adaptations to help the organism survive and thrive in its environment.

Soil organisms, such as mycorrhizal fungi, impact the rate of succession in ecosystems. Mycorrhizal fungi have a mutualistic relationship with various species of plants and increase the plant growth and survival. Sand dunes often lack mycorrhizal fungi, and a researcher wanted to determine the effect of adding mycorrhizal species to sand on disturbed beaches on grass growth. The researcher set up various mycorrhizal communities at disturbed beaches in different locations on the east coast of the United States. Identify the independent variable in the study.
Answer:
The amount (number) of mycorrhizal fungi
Explanation:
In a scientific experiment/study, the independent variable is the variable that isn't changed by other variables, while the dependent variable is the variable that is being measured during the experimental procedure. The independent variable is manipulated by the researcher (in this case, the amount of mycorrhizal fungi), thereby affecting the dependent variable (in this case, grass growth). In consequence, a variable is dependent because it 'depends' on the independent variable.

The animals were probably ancestors of today's horses.
The animals had no relationship to one another.
Today's horses and these animals probably lived together at some time in the past.
Today's horses are faster than these animals were.
Answer:
THE ANSWER IS: A it makes the most sence.
Explanation:
The animals were probably ancestors of today's horses. Thus option A is correct.
What are fossils?Fossils are the preserved remains, traces, or traces of living things from a bygone geological epoch. Bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants are some examples of the fossils.
Paleontology is the study of fossils, their ages, how they formed, and their evolutionary importance. Specimens older than 10,000 years are usually considered fossils. The oldest fossils are about 3.48 to 4.1 billion years old.
There are many processes that lead to fossilization, including permineralization, casting and molding, true mineralization, displacement and recrystallization, impression, carbonization, and bioimulation.
Therefore, if both fossils have similar structure then the animals were probably ancestors of today's horses.
