Microscopic life in the soil can play many roles, both positive and negative. Which of the following combinations of soil life would usually be the best choice to ensure long-term sustainable agriculture? all broad classes of microbiota in balance nematodes and symbiotic bacteria microscopic non-animal life, plus earthworms sterile soil free of nematodes
Answer:
Symbiotic bacteria plus earthworms.
Explanation:
Symbiotic bacteria is a type of bacteria which in which a bacteria lives in association with other organisms and gain benefits from one another. The nitrogen fixing bacteria lives in the roots of the leguminous plants which fixes nitrogen for the plant and in return, the plant provides food. earthworms increased the availability of nutrients, better drainage, and aeration of the soil which is very necessary for the plant growth.
Answer: all broad classes of microbiota in balance

Describe the offspring of a true-bred white flowering pea plant
The offspring of true-bred white-flowering pea plants have the same traits. So, they are white in color.
What is offspring?Offspring is the product of reproduction. It acquires the characters of parents and consists of some variations as well.
While performing a cross between pure red and pure white, pink flowers are obtained in the F1 generation due to incomplete dominance. Now, on selfing, this F1 generation, red, pink, and white flowers are produced in the ratio of 1:2:1, where true-bred white flowers are obtained.
Therefore, the offsprings of a true-bred white flowering have the same traits, and they are recessive in nature.

What happens when a mutation occurs during the formation of gametes in a parent sex cell?
Answer:
if it's a silent mutation, nothing significant will happen, but if it's a frame shift mutation, it can make the baby deform.
Answer: most mutations will have no effect, although in rare cases an abnormal foetus may develop and even more rarely the embryo may be non-viable.
Explanation: A mutation at this stage is probably due to a random result of an external effect (cosmic ray for example) and probably a change in one nucleotide (a single nucleotide polymorphism). It is unlikely that the mutation will be an insertion, deletion or inversion.
Whatever the mutation, it is unlikely to occur in the relatively small proportion of coding DNA. If it does occur in coding DNA it is still unlikely to be at a critical codon. If it does occur at a critical codon, it may still code the the same amino acid, particularly if it is a third nucleotide.
There is a low probability that the mutation will prevent the formation of a fully functional protein, by altering a critical amino acid or altering the frame by changing a stop codon, or creating a stop codon, or altering a promoter region. Even in this case, any error can be avoided if the other allele is intact.
It is possible, however, that a mutation could result in a development abnormality (cystic fibrosis is an example), or a non-viable embryo.

What genotype would a heterozygous short haired
guinea pig have?
What genotype would a pure breeding short haired
guinea pig have?
What genotype would a long-haired guinea pig have?
Answer:
What genotype would a heterozygous short haired
guinea pig have? Ss
What genotype would a pure breeding short haired
guinea pig have? SS
What genotype would a long-haired guinea pig have? ss
Explanation:
I just used S to substitute for my alleles, but you can use any letter. (For example: Ee, EE, ee)
If H is the dominant allele for short hair, we would have the followng genotypes:
Heterozygous short haired: Hh
Pure breeding short haired: HH
Long-haired guinea pig: hh
What is a Dominant Allele?A dominant allele is an allele of a trait that always expresses itself in the presence of a recessive trait in an allelic pair. Capitral letter is usually used to denote the dominant allele.
Let H represent short hair (dominant allele)
h represents long hair (recessive allele)
Therefore, we would have the following:
Genotype for heterozygous short haired would be: Hh
Genotype for pure breeding short haired would be: HH
Genotype for long-haired guinea pig would be: hh

How is the function of a leaf different from that of a stem or root?
Answer:
the leaf of a plant takes the sunlight and converts it into food the stem and roots are for stability and for water absorbtion
Explanation:
Answer:
Seed plants have three main parts that serve specialized functions: roots, stems, and leaves. Roots help to anchor the plant in the ground as well as absorbing water and nutrients from the soil. ... Leaves carry out photosynthesis, which is the most important way that plants produce the energy to live.
Explanation:
Why is Alternation of generation important to plants
Answer:
The alternation of generations allows for both the dynamic and volatile act of sexual reproduction and the steady and consistent act of asexual reproduction. When the sporophyte creates spores, the cells undergo meiosis, which allows the gametophyte generation to recombine the genetics present

What are the advantages and disadvantages of using renewable and nonrenewable energy resources? Use evidence from the lesson and scientific reasoning to support your answer.
Answer:
The answer to this question is given below in this explanation section.
Explanation:
Advantages of renewable energy resources:
Using renewable energy over fossil fuels has a number of advantages.Here are some of the top benefits of growing green.
Renewable energy won't run out:Renewable energy technologies use resource straight from the environment to generate power.These energy sources include sunshine,wind,tides,and biomass,to name some of the more popular options.
Maintenance requirements are lower:In most cases,renewable energy technologies require less overall maintenance than generators that use traditional fuel sources.This is because generating technology like solar panels and wind.
Renewables save money:Using renewable energy can help you save money long term.Not only will you save on maintenance costs,but on operating cost as well.When you are using a technology but generates power from from the sun wind team natural processes.
Renewable energy has numerous health and environmental benefits:Renewable energy resources emit little to no greenhouse gases or pollutants into the air.
Renewable lower reliance on foreign energy sources:With renewable energy technologies you can produce energy locally.The more renewable energy you are using for power needs.
Disadvantages of renewable energy:
Higher upfront cost:You can save money by using renewable energy the technologies are typically more expensive upfront by traditional energy generators.
Intermittency:Through renewable energy resources are available around the world many of these resources are not available year around.
Storage capabilities:Because of this intermittency of some renewable energy resources there a high need of energy storage.
Geographic limitations:The united states has a diverse geography with varying climates topographies vegetations and more.

What is it called when the amount of water that evaporates equals the amount that condenses?
Answer:
Look down!! ;)
Explanation:
So, as the number of water vapor molecules increases in the air above the water, the condensation rate increases, too. The condensation rate will continue to increase until it matches the evaporation rate, which is a state called equilibrium, meaning the condensation rate equals the evaporation rate.
Hope this answers your question!! ;)

To calculate the speed of wave, what two pieces of information do you need about the wave ?
help asap plz i’m being timed!!!
Answer:
Wavelength and Frequency
Explanation:
The speed of a wave can be related to the speed of an object which is calculated using:
[tex]Speed = \frac{Distance}{Time}[/tex]
So: the speed of a wave (v) is calculated using:
[tex]v = f * L[/tex]
Where:
[tex]f= Frequency[/tex]
[tex]L = Wavelength[/tex]
Frequency is calculated as:
[tex]f = \frac{1}{T}[/tex]
Where:
[tex]T = Period[/tex]
This means that the two basic information needed are the wavelength and the frequency of the wave

Why is algae able to endure photosynthesis when grown under green light? (has something to do with absorbing the color green)
Chlorophyll makes plants and algae appear green because it reflects the green wavelengths found in sunlight, while absorbing all other colors.
However, chlorophyll is not actually a single molecule. There are 6 different chlorophylls that have been identified. The different forms (A, B, C, D, E and F), each reflect slightly different ranges of green wavelengths. Chlorophyll A is the primary molecule responsible for photosynthesis. That means that chlorophyll A is found in every single photosynthesizing organism, from land plants to algae and cyanobacteria. The additional chlorophyll forms are accessory pigments, and are associated with different groups of plants and algae and play a role in their taxonomic confusion. These other chlorophylls still absorb sunlight, and thus assist in photosynthesis. As accessory pigments, they transfer any energy that they absorb to the primary chlorophyll A instead of directly participating in the process. Chlorophyll B is mainly found in land plants, aquatic plants and green algae. In most of these organisms, the ratio of chlorophyll A to chlorophyll B is 3:1. Due to the presence of this molecule, some organizations will group the green algae into the Plant Kingdom. Chlorophyll C is found in red algae, brown algae, and dinoflagellates. This has lead to their classification under the Kingdom Chromista. Chlorophyll D is a minor pigment found in some red algae, while the rare Chlorophyll E has been found in yellow-green algae. Chlorophyll F was recently discovered in some cyanobacteria near Australia. Each of these accessory pigments will strongly absorb different wavelengths, so their presence makes photosynthesis more efficient.

How does Sea walnuts impact humans?
How to stop Sea Walnuts from spreading and How Sea walnuts can be managed?
3 benefits that will occur if Sea walnuta is removed.
Please helo me I have no idea how to answer these.
Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.
