Answer:
While spiral galaxies are bright, elliptical galaxiesare dim. Spiral galaxiesare hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born.

Geckos are a type of small lizard that live in tropical areas. Geckos are often eaten by birds, snakes and larger lizards so they need to blend into their surroundings. In one area, scientists had always found brown and green geckos that blended in with the grass and the leaves on the ground. Over time, though they found yellow geckos in the same population. Three students were talking about why there were yellow geckos. Ciena thought that the change came from a mutation in the population. Tibor thought the change came from the environment. Sasha though that Ciena and Tibor were both right. Who do you agree with and why do you think that?
Answer:
Not going to say this is right but, I think that Tibor is correct because if the land has changed more over time then the yellow ones have adapted to the new living conditions while the green one have found ways to live in that environment.
1)What is a trophic level?
2) explain how energy travels through food web ? your response must include the following terms:
Decomposer,producer, primary, consumer , 10%.
3)why is energy reduced at successive trophic levels?
1. The trophic level is something's position in the food chain/food web.
2. Energy travels through out the food chain because all the animals eat each other and take each other's energy. The decomposers are eaten, the producers are eaten, but the primary consumers get all the energy.
3. The energy decreases because each animal decomposes the energy a little, before getting eaten. By the time the food reaches the top of the web, the energy is barely left.

Which of the following is important in creating a genetically diverse population?
Answer:
What are the choices so that i can answer the question
You would need to combine the genes from 2 different populations. Since lowering the diversity of a population with cause there to be no variation. Which means that then the population cannot evolve in different ways such as to changing environmental factors and can face an extreme risk of extinction. I hope this helped!
Explain the importance
of decomposers to the overall
biogeochemical cycle.
Answer: Decomposers plan an important role in the biogeochemical cycling for nutrients in the environment as they are responsible for the breakdown and return of nutrients back to the environment in their native state.
Decomposers are essential for the biogeochemical cycle as they facilitate the recycling of nutrients, provide energy for other organisms, and help maintain the health and balance of ecosystems by Breaking down organic matter, Recycling nutrients, Energy flow and Detoxification.
Without decomposers, organic matter would accumulate, nutrients would become locked up, and energy flow within ecosystems would be disrupted.
Decomposers play a crucial role in the overall biogeochemical cycle. Here's why they are important:
Breaking down organic matter: Decomposers, such as bacteria and fungi, break down dead plants, animals, and other organic materials into simpler compounds. They do this through the process of decomposition, where they release enzymes that break down complex molecules into smaller, more manageable forms.
Recycling nutrients: By decomposing organic matter, decomposers release essential nutrients back into the ecosystem. These nutrients, such as carbon, nitrogen, phosphorus, and sulfur, are then made available for uptake by plants and other organisms. This recycling of nutrients is vital for maintaining the balance and productivity of ecosystems.
Energy flow: Decomposers also play a crucial role in energy flow within ecosystems. When they break down organic matter, they release energy in the form of heat. This energy can then be used by other organisms in the ecosystem, such as primary consumers (herbivores) and secondary consumers (carnivores), to carry out their life processes.
Detoxification: Decomposers are capable of breaking down and detoxifying harmful substances and pollutants in the environment. For example, certain bacteria can break down pesticides and other chemical pollutants, helping to reduce their negative impact on the ecosystem.

The carrying capacity of an ecosystem will most likely become unbalanced when?
Answer:
In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. ... 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.
Explanation:
When resources are depleted faster than they are replenished, the species has reached its carrying capacity. If this happens, the population will shrink in size.
What is carrying capacity?Carrying capacity is defined as the average population size of a species in a given habitat.
Environmental factors such as adequate food, shelter, water, and mates limit the species population size. If these requirements are not met, the population will decline until the resources recover.
Carrying capacity, or the maximum number of people that an environment can support over time without destroying or degrading it, is determined by three key factors: food availability, water availability, and space.
Carrying capacity is the maximum number, density, or biomass of people that a given area can sustainably support.
This is likely to change over time and is influenced by environmental factors, resources, and the presence of predators, disease agents, and competitors.
Thus, any disturbance in these factors can lead to an unbalanced carrying capacity.

Have a great day/night and stay safe! :D :)
I'm not quite sure either, but from the instructions it appears that you should have some sort of "subject" and two of the subject's relatives. Then you just have to list if the subject and the two relatives show the traits. I believe that the subject is either you, since the course says "Your Genetic Traits"
I hope this helped a bit.

MAGMA CHAMBER IS A
Answer: A caldera is a large depression formed when a volcano erupts and collapses. During a volcanic eruption, magma present in the magma chamber underneath the volcano is expelled, often forcefully. When the magma chamber empties, the support that the magma had provided inside the chamber disappears.
Explanation:
The stems and fruits of pineapple plants contain a group of protein-digesting enzymes collectively
called bromelain and often used as an antibrowning agent for fruits and vegetables. Fruits and
vegetables brown when they are bruised during transport or sliced and exposed to air. This browning is
controlled by enzymatic pathways that produce brown pigments. The browning of fruits and vegetables
reduces the nutritional value of the food, so antibrowning agents such as bromelain are used.

its transformation! so option B
Explanation:
Within the image you can see the final product is a "Genetically Transformed cell" and within lesson 03.01 HONORS on flvs there are multiple dropdowns giving definitions. one of these dropdowns contains this exact image, and it is titled 'Transformation' in the lesson.
I am currently taking this course, so actually searched brainly for that answer initially. I decided to take the test and come back with the right answer to help any other students like me! A tip for taking tests on flvs: You can have flvs open on multiple tabs, so the best way to take tests like this is to have the test open on one tab, and the lesson plan on another tab. That way you can read through the lesson and look at any graphs while actively in the test! Hope I could help at least a little, have a great school year everyone.
