Gina designed a model to show the steps in the Nebular theory of formation of planetary systems. Which of these diagrams best represents the first step of Gina's model?
The picture shows an irregular shaped cloud with several dust particles within its boundary. There are seven arrows pointing from the edge of the cloud towards the center of the cloud. The label below the picture reads 'Condensation and contraction of cloud due to gravity'
The picture shows an irregular shaped cloud with several dust particles within its boundary. A circle above the cloud shows that the cloud and dust are rotating in the anticlockwise direction. The label below the picture reads 'Rotation of cloud of gas and dust'
The picture shows an elliptical orbit with a planet on it. At the center of the orbit there is a circular sun. The label below the picture reads 'Formation of planet'
The picture shows an elliptical disc. At the center of the disc there is a circular sun. The label below the picture reads 'Fusion of gas and dust at the center to form the Sun'
Answer:
B.) rotation of cloud of gas and dust
Explanation:
According to Nebular theory, the sun and the planets were formed from the Solar Nebula. Initially a fragment of the molecular cloud of dust and gases collapsed under its own weight. This contracted portion starts to rotate until a high enough temperature and pressure causes the nuclear fusion reaction in the core to start and form the Sun. The planets were formed from rest of the part of the cloud.

Quite confused can anyone help?
Answer: A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits
Explanation:
A class is learning about the evaporation step in the water cycle using a simple model. The model consists of a 1-L container of water. When the container is open, and it receives sunlight, the water can freely evaporate from the container. The students design an experiment using the model. In the experiment, the container will be filled and left open outside from dawn until dusk at different times of the year. The students will run the experiment only on days with clear weather. As a basis of their experiment, the students make an assumption that more water will evaporate from their model when more solar energy is present. Which of the following is a result that the students could predict in order to test their assumption?
A.
Equal amounts of the water will evaporate on summer days and winter days.
B.
Less of the water will remain in the container after one day in summer than after one day in winter.
C.
Less of the water will remain in the container after one day in winter than after one day in summer.
D.
Some of the water will evaporate on winter days but not on summer days.
Infectious Disease Investigation
The students are to investigate an infectious disease.
They will choose a specific infectious disease, such as the flu, common cold, or
COVID-19, and research its causes, symptoms, and preventive measures.
Students are to create informative posters or presentations about the disease,
including its transmission methods and ways to protect oneself from infection.
They will explain the importance of personal hygiene and vaccination in preventing
the spread of infectious diseases.
Following the summer vacation, the students will be given an opportunity to present
their findings to the class or organize an "Infectious Disease Awareness Campaign"
where they can share their posters or presentations with their peers.
Answer:
The common cold is an illness affecting your nose and throat. Most often, it's harmless, but it might not feel that way. Germs called viruses cause a common cold.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

How do auxins cause plants to bend?
A) Auxins make plant cells grow larger towards the light causing it to bend.
B) Auxins make plant cells grow heavier causing it to tip on one side.
C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

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.

Explain how photosynthesis changes the radiant energy from the sun into chemical energy (sugar) through the process of photosynthesis.
Answer:
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. ... The electrons go to the chlorophyll, while the protons contribute to a proton gradient that is used to power the synthesis of a second energy-carrying molecule, ATP
During the procedure of photosynthesis, mild penetrates the mobileular and passes into the chloroplast. The mild power is intercepted via way of means of chlorophyll molecules at the granal stacks.
Some of the mild power is transformed to chemical power. During this procedure, a phosphate is delivered to a molecule to reason the formation of ATP.
What is photosynthesis?
Photosynthesis, is the procedure via way of means of which inexperienced vegetation and positive different organisms rework mild power into chemical power.
During photosynthesis in inexperienced vegetation, mild power is captured and used to transform water, carbon dioxide, and minerals into oxygen and power-wealthy natural compounds.
Hence concluded that photosynthesis changes the radiant energy from the sun into chemical energy (sugar) through the process of photosynthesis.

What is an ecosystem and what are its parts and functions?
What can challenge an ecosystem?
What are the roles of the water and food cycles in an ecosystem?
An ecosystem is a structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interactions between organisms and their environment.
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue.
Parts & Functions Of an Ecosystem
The functions of the ecosystem are as follows: It regulates the essential ecological processes, supports life systems and renders stability. It is also responsible for the cycling of nutrients between biotic and abiotic components. It maintains a balance among the various trophic levels in the ecosystem.
What are the major parts of an ecosystem? An ecosystem includes soil, atmosphere, heat and light from the sun, water and living organisms.
Challenges For An Ecosystem
Some of the primary challenges include, but are not limited to, habitat loss, climate change including sea level rise, and levee stability.
The Role and Function of Water
Water cycle have several impacts on the nature - it takes part in weather, erosion and watering plants.
In short term it is positive, to see green grass and trees, not just bonedry dead nature.
In longer term we can see weather changing, clouds made of tiny drops of water coming and leaving - changing humidity (important for fungi and liches), local temperature changes etc.
Longest takes erosion and it is mostly about changing soils structure and nutritients for plants. Erosion can be also seen on riverbeds - in soft rocks/soils being wider, in harder rocks narrow. Also sedimentation in delta is important for development of border ecosystems.
Water makes organisms live and rocks move, that is the importance of water cycle.

in danger of becoming extinct in the near future
plants or animals that migrated to new places where they are not native
consumers that eat only animals
Answer: plants or animals that migrated to new places where they are not native
Explanation:
Answer:
plants or animals that migrated to new places where they are not native
Explanation:
Invasive species are non-native species that cause harm to the environment, economy, or human health. These species often outcompete native species for resources, prey on native species, and disrupt the natural balance of the ecosystem. They can also spread diseases to other species, and cause significant economic damage. Examples of invasive species include the emerald ash borer, zebra mussels, gypsy moths, and Asian long-horned beetle.
