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.

What are the challenges of traveling to and living on Mars?
Answer:
Here I hope this can help you with your question! :)
Explanation:
You might be travelling with other astronauts in a journey that will take between seven and 12 months, packed in a tight space. So you’ll need to stretch and probably find a way to have part of the spacecraft spinning to create artificial gravity. Having no gravity for a long time can cause a lot of painful health problems for astronauts. Then there’s the powerful cosmic radiation that comes mostly from our Sun. It can damage electronic equipment on board and create health problems for the crew. You and the crew will have to solve these problems on your own. The atmosphere is not breathable: it is only 1% the thickness of our atmosphere, mostly made of carbon dioxide, argon, and nitrogen with only a small amount of oxygen. Growing plants on Mars is not going to be easy. The soil is really salty and acidic. It is still unclear if we should bring bacteria to Mars to help plants grow (as they do on Earth). Finally, I would say any mistake in flight or during the exploration can hurt or kill you. The room for error is really narrow. Why on Earth would you engage in such a dangerous, life-threatening endeavour? I guess the answer lies in what has made humans explore throughout the centuries. We are always looking for the next frontier.
Answer:
- Travelling from Earth to mass requires a greater magnitude of escape velocity in order to overcome the Earth's gravitational attraction.
- Travelling to Mars is a great distance which is approximately the twice of Earth's distance from the sun (approximately 3.0×10^11 m), hence the Traveller has a possibility of not reaching the destination.
- Travelling to Mars requires a skilled Traveller and experienced, yet those travellers are scarce allover the World.
- It is also very expensive.
- Mars has a different and a greater gravitational attraction than that of the earth, hence a person of earth may not cope with it.
-Mars is very hot than Earth, hence the living on it is affected by the climatic diversion
What type of energy is made during respiration
Answer:
During the process of glycolysis in cellular respiration, glucose is oxidized to carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
Answer:
The source of the energy required to regenerate ATP is the chemical energy stored in food (glucose) The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP. So I believe it would be chemical energy

What agent of deposition is this? Gravity,wind, waves, running water or glaciers.
Answer:
The answer is "running water or glaciers".
Explanation:
The material is placed if erosion agents can longer carry sand. For instance, if another fluvial water slows at the river mouth, soils become rivers. The four key reasons for accumulation was its movement of reinforced the fact material surface, air, ice, liquid, and inertia, accumulated at the loss with enough kinetic energy throughout the fluid to create substrate layers. Accumulation can also apply to natural head moves or processes create of soil.

Scientists were examining the maize genome. They had two specimens: one control and one specimen that had undergone mutagenesis. They saw that the mutant specimen underwent a knockout caused by a nucleotide exchange in the DNA. When they compared gene sequences, they saw same number of nucleotide bases. Which type of mutation had most likely occurred? deletion insertion inversion substitution
Answer:
substitution
Explanation:
A substitution is a point mutation where a nucleotide base (either adenine, guanine, thymine or cytosine) is replaced by a different base pair. In contrast to insertions or deletions, substitutions don't change the number of bases in the DNA sequence. Moreover, inversions are large genetic rearrangements where the genetic sequence is reversed. A substitution may have different effects: change a codon to another (changing the protein sequence when codons are translated into amino acids), produce a stop codon, cause synonymous mutations (i.e., neutral mutations that don't alter the amino acid sequence due to the degeneracy of the genetic code), etc.
What would be the next step in this experiment? A. ask questions and construct a hypothesis B. make observations and draw a conclusion C. construct a hypothesis and record data D. analyze the results and make a conclusion
Answer:
The next step is Prove or disprove the hypothesis on the basis of conclusions
Explanation:
The right step to follow the experiment is :
first step: Ask questions and make hypothesis
second step: Make a observations and draw conclusions
third step: Construct a hypothesis and record a data
fourth step: Analyze the results and make a conclusion
Fifth step : Prove or disprove the hypothesis on the basis of conclusions
If capital D = the allele for dimples, and lowercase d = the allele for NO dimples, what percentage of the offspring will show having dimples, with parents having genotype Dd (capital D and lowercase d) and genotype dd (two lowercase ds)?
If D is the allele for dimples and d is the allele for no dimples, a percentage of offspring with genotypes Dd is 50% and 50% dd will be produced with no dimples.
How will the allele for dimple express?The dimple appears when the D is present, which occurs in both the purebred dominant case (DD) and the heterozygous case (Dd), so when the dd is present, no dimple is seen. The dimple is dominant over the no dimple, so when the heterozygote Dd crosses with the purebred dd then 50% will have dimples and the other 50% won't, as the heterozygotes will produce both D and d types of alleles that will combine with d to make two types of offspring.
Hence, if D is the allele for dimples and d is the allele for no dimples, a 50% percentage of offspring with genotypes Dd and 50% of offsprings with genotype dd will have no dimples.

how does the structure of DNA determine the structure of RNA?
A- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases cytosine in DNA and uracil in RNA will pair together when DNA acts as a template for constructing RNA.
B- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases uracil in DNA and guanine in RNA will pair together when DNA acts as a template for constructing RNA.
C- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases adenine in DNA and thymine in RNA will pair together when DNA acts as a template for constructing RNA
D- The nucleotide sequence of DNA determines the nucleotide sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA
The nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).
During transcription, a sequence of DNA is used as template to create an RNA, usually an mRNA.In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Guanine, Thymine, Cytosine and Adenine.According to the base pair rules, Adenine pairs with Thymine (Uracil in RNA), whereas Guanine pairs with Cytosine.In conclusion, the nucleotide sequence of DNA determines the sequence of RNA because only the bases guanine in DNA and cytosine in RNA will pair together when DNA acts as a template for constructing RNA (Option D).

Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence
Answer:
It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.
