If the uncertainties are random, the more measurements you make the more likely you are to mess up.
Compare and contrast the advantages and disadvantages of selective breeding versus genetic modification. Why might a person choose to use selective breeding over genetic modification? Why might a person choose to create a GMO over a selectively bred organism? Use three to five sentences to formulate your argument. 100 POINTSSS
Answer:
Here are just some facts that you can put into paragraph form:
Pros of GMO:
They are "perfect" in theory
Most likely won't have any diseases or infections
Genetically modified so everything will be almost exactly the way people want it to be
Pros of Breeding:
Definitely more organic and healthy (i guess)
More authentic - they're the "real stuff"
People might feel safer when eating organic stuff

Read the following excerpt and answer the question:
Emilie Dressaire, professor at Trinity College (Hartford, CT), and her colleague Marcus Roper (UCLA) discovered that mushrooms create their own microclimates. They create their own moisture through evaporation, which is when a liquid turns into a gas. Heat energy is used in this process, leaving the mushrooms cool and moist.
Use your own words to summarize the effect of thermal energy on a mushroom's environment and how this sustains life. (4 points)
Answer:
Mushrooms can reproduce by using thermal energy to create conventional currents, which are known as pockets. Following the formation of the pockets, the currents disperse microscopic spores in the surrounding air. As a result of the spread, a large spore cloud forms, which is visible at night.

Explanation:
Please help ASAP! Question in photo!
Answer:
High mass stars have to generate a lot of energy in order to balance the force of gravity. Therefore they are very hot and luminous. That explains their position high on the Main Sequence. On the other hand, low mass stars have to generate little energy in order to balance the force due to gravity.

if we looked at weather balloon data taken at 12:00 noon instead of 12:00 midnight, what do you think we would see in that data?
Answer:
So we are looking at the data to see what we would find.
Explanation:
So if the balloon data was collected on a sunny day at noon we would probably see some higher temperatures and more molecules. But if it was taken on a cold and rainy day, we would see lower temperature and water molecules, and lower air pressure. Hope this helps

Observe the following protists below. Which statement best compares how a euglena and paramecium obtain food?
Both the euglena and paramecium use flagella to obtain food.
The euglena uses photosynthesis to make its own food and the paramecium uses cilia to sweep food into its oral groove.
The paramecium uses photosynthesis to make its own food and the euglena uses cilia to sweep food into it's oral groove.
The paramecium uses a pseudopod to obtain food while the euglena uses cilia.
The euglena uses photosynthesis to make its own food and the paramecium uses cilia to sweep food into its oral groove
The euglena uses photosynthesis to make its own food and the paramecium uses cilia to sweep food into its oral groove.
What is euglena ?
It is the alga that has the ciliates and flagella also to obtain the movement .
The paramecium uses cilia to sweep food into its oral groove Paramecium are heterotrophs and have to devour meals. The location of the paramecium that looks pinched inward is referred to as the oral groove. Cilia sweep meals into this location. Food enters the paramecium via the oral groove (mouth pore) and is going to the gullet (shadeation the oral groove and gullet mild brown).Euglenas create their personal meals via photosynthesis, the manner of soaking up daylight to synthesize meals from carbon dioxide and water. An eyespot on the the front stop of the euglena detects mild, and its chloroplasts (systems that include chlorophyll) lure the daylight, permitting photosynthesis to occur.\Read more about chloroplasts refer link :

Describe the shape of the western gorilla’s hands
Describe the shape of the European mole’s hands
In an ecosystem, western gorillas hands are more flexible and can bend easier than the european moles hands, the moles hands are mostly just claws, used to dig, while the gorillas hands are more human like.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Invasive species are
the first species to populate to a new area
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.

So in class, we were asked to add adaptations to our animal and I was wondering if adding goo (a colorless layer, like sweat but thicker) would make an animal fly faster?
Answer:
Not necessarily.
Explanation:
The texture of an animal's skin isn't necessarily going to help it fly. Flight consists of aerodynamics and assests like wings, a fanned tail, and/or a pointed figure, like a bird possesses. Adding this slime/goo that you mentioned will not add to it's aerodynamics, meaning that the answer would be no.

1.) what are some cleaner options to produce energy? How do they work?
2.) what are the effects of air pollution on the environment and people?
Answer:
1.Solar panels, wind turbines, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. A Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
2.Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).
What process of the carbon cycle is likely causing the increase in carbon dioxide levels shown in the graph above?
