Answer:
A
Explanation:
What are potential impacts on society and the environment of using a genetic approach to improving food productivity? Do you think this is how we should fix the worlds hunger problem? Why or why not? Please explain…
Answer:
- Society: the use of genetic improving techniques may have a positive impact through crop improvement of traits of agronomic importance such as, for example, resistance to biotic and abiotic stresses.
- Environment: the development of genetically modified crops conferring resistance to pesticides may have a negative effect on wildlife species (both plants and animals) and humans living in such agroecosystems.
Explanation:
In crops, genetic improvement technologies can be defined as the techniques associated with the development of better crop varieties, i.e., varieties that have higher grain yield, produce more biofuel, higher fiber content, etc. Genetic improvement techniques include, among others, selective breeding and genetically modified organisms. In crops, genetic improvement techniques have the potential to reduce hunger in the world. However, it is important to note that genetic engineering may be associated with the horizontal transference of genes and the development of genetically modified organisms (GMO), which may have harmful effects on wildlife species and humans, thereby GMO crops must be carefully assessed before their release into the field.
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

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.

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

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!! ;)

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.
Answer:
Renewable energy has several advantages and disadvantages. The advantages of renewable energy include unlimited supply, low environmental impact, and increased opportunities for employment. While these advantages are nice, there are some disadvantages. These include less reliability than nonrenewable energy, difficulty storing and transporting the energy, and higher costs.

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

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.
