Answer:
Ver explicacion
Explanation:
Los microorganismos son beneficiosos y perjudiciales para los seres humanos.
Los microorganismos son útiles en la producción de alimentos. Se utilizan en la elaboración de productos alimenticios como queso, pan, vino, etc.
En segundo lugar, los microorganismos están involucrados en la producción de vitamina K en el cuerpo.
por otro lado, los microorganismos provocan enfermedades que conducen a la morbilidad y mortalidad de los seres humanos.
Además, los microorganismos provocan el deterioro de los alimentos.
When hydrogen nuclei are fused together to form a helium nucleus, the mass of the product is 0.7% less than the mass of
the reactants. If 1 gram (1 x 10-3 kg) of protons were completely fused into helium nuclei, the mass of the helium nuclei
produced would be 6.8 x 10-6 kg less than the mass of the protons.
Using the equation E = mc2, calculate how many joules of energy would be produced by converting 6.8 x 10-6 kg of matter
into energy in this fusion reaction. Use c = 3 x 108 m/s.
E = 6.05 x 1011 kg x m²/s2
E = 6.10 x 1011 kg x m2/s2
E = 6.12 * 1011 kg x m2/52
E = 6.25 x 1011 kg * m/s2
E = 6.30 x 1011 kg m/s2

Many farms and ranches use reservoirs, like the one shown here, to collect and store rainwater. Reservoirs ensure there is enough water for crops and animals. Describe the type of soil that would be best for lining a reservoir.
Answer: Water harvesting (WH) and small-storage technologies are key water-related ... technologies can also help provide water for domestic use, livestock, fodder and tree production, ... WH is the collection of rainfall runoff for subsequent beneficial use. ... of rainfall entering soil storage, where it can later be used directly by plants.
Explanation:
The type of soil that would be best for lining a reservoir is Bentonite Clay.
What is Bentonite Clay?Montmorillonite, which can either be Na-montmorillonite or Ca-montmorillonite, makes up the majority of bentonite, an absorbent swelling clay. Compared to Ca-montmorillonite, Na-montmorillonite can swell much more.
A very fine clay soil is bentonite clay. More water is absorbed by it than by other kinds of clay. Bentonite should be compressed after being combined with coarse material.
The clay then swells up and becomes impenetrable when water is added to the reservoir.
Reservoirs, like this one, are frequently used by farms and ranches to catch and store rainfall.
Reservoirs guarantee that there is enough water for both animals and crops. Bentonite Clay is the best kind of soil to use for reservoir lining.
Thus, the answer is Bentonite Clay.

In order to protect aquifers near landfills, material is placed under the soil to prevent pollution. Which property must the protective material possess?
Answer:
The correct answer is - low permeability.
Explanation:
Low permeability does not allow the pollutant to leak or diffuse from the pollutant to the ocean or aquifers near landfills. The permeability of protective material should be lower as they lead the pollutants to the soil, and environment such as contents of battery, toxic plastic, and other pollutant toxins to the soil and aquifers.
Thus, the correct answer is - low permeability.

D
Explanation:
It's the building and sequencing of your DNA.
The cells illustrations below represent different stages of meiosis. In which order would these stages
occur?
Answer:
1,2,4,5,6,3
Explanation:
Meiosis involves two rounds of cell division to create 4 haploid cells, therefore, we know that 3 must be the final stage.
Meiosis starts with a diploid cell following DNA replication. Therefore, stage 1 is the first.
Homologous chromosomes align (as shown in stage 2). Then, the chromosomes are separated to opposite poles of the cell (4) and two new cells start to form, before the cell divides (5).
Then, the chromosomes in these two cells align at the centre of the cells (6), and the sister chromatids are pulled apart to create four haploid cells (3)
he cell performs many cellular processes to ensure the cell is able to maintain homeostasis. The organelles in cells work together to perform different functions to keep the cell balanced. The chloroplast and the mitochondria are two important organelles that provide cells with different types of energy.
Experiment 5
Lisa is working on a science project. Her task is to answer the question:
"Does Rogooti (which is a commercial hair product) affect the speed of hair growth"? Her
family is willing to volunteer for the experiment.
1. Identify the hypothesis in this experiment.
2. State a conclusion to support your hypothesis. 3. State a conclusion that refutes the hypothesis.
Answer:
Hypothesis: The commercial hair product Rogooti accelerates hair growth.Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.Conclusion 2: Rogooti does not seem to have any effect on hair growth.Explanation:
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur comprehensively. There must be a logical relation between variables. It must be objective.
To answer the question, Lisa might propose the following hypothesis, which needs to be corroborated.
Hypothesis: The commercial hair product Rogooti accelerates hair growth.
Experiment: Her family is a volunteer for the experiment, so all of them will use an ordinary hair product for a month. Before and after this period they will take notes of how long their hair is before and after the first part of the experiment. After this, they will cut down their hair to the initial length, and they will start using Ragooti for another month. After this last one, they will measure hair length again. Finally, Lisa will compare the initial length with the one after the first month and after the second month to analyze how Rogooti affects the speed of hair growth.
Result 1: When comparing lengths, Lisa will see that the hair of all her family members grew longer during the second month.
Conclusion 1: Rogooti makes hair grow faster than it would normally do when using an ordinary product.
Result 2: When comparing lengths, Lisa will not see any significant difference in the hair growth of her family during the first and the second month.
Conclusion 2: Rogooti does not seem to have any effect on hair growth.

Metamorphic rocks are formed due to erosion of soil O cooling of magma weathering of rocks O heat and pressure
Answer: Heat and pressure.
Explanation: Sedimentary rocks form from erosion of soil and weathering. Igneous rock is formed from the cooling of magma. Metamorphic rocks form from a ton of heat and pressure below the ground.
Metamorphic rocks are formed due to heat and pressure, hence option D is correct.
What is Metamorphic rocks?Sedimentary rocks are created through weathering and soil erosion. Magma cools, which results in the formation of igneous rock. A tremendous amount of pressure and heat underground causes metamorphic rocks to develop.
In the world, there are three different types of rocks: igneous rocks, sedimentary rocks, and metamorphic rocks.
Volcanic magma seeped from the volcano to the earth's surface, where it cooled and hardened to produce igneous rocks.
Igneous rocks are the source of sedimentary rocks, which develop through time from the eroded remnants of igneous rocks.
Therefore, Igneous and sedimentary rocks undergo metamorphism as a result of heat and pressure over millions of years.

For an ongoing way to collect the evidence until the trial starts video making will be an appropriate procedure.
Scene of crime is a place where potential evidences related to prove crime can be found. Video making is an excellent approach to capture the entire scene of crime. It will help in recording all the details, sequence of events that could have taken place, and details of all evidences in a single shot. Video making can be useful for reconstruction of crime event. Video making is also appropriate to record the activities of the criminal till he or she reaches court for the trial. Note making can sometimes become presumptive related to case, photograph can give the details of the evidences but cannot relate them with the entire scene of crime, drawing can be done in the form of sketching of the scene of crime using scalar measure to establish the location of evidence to the point.Learn more about evidence:

(c) Explain one adaptation that helps grasses succeed in grasslands, rather than forests.
Answer:
grasses and grasslands can't go anywhere to keep themselves safe so instead they adapt to fire. fire helps keep the grasslands from being overgrown by bushed and trees and turning into a forest.
Explanation:
Grasses store their nutrients in their roots and hence can sprout quickly after a fire.
GRASSLAND:
Grassland is a zone characterized by the dominance of grass species and very few trees or shrubs. The dominance of grasses in a grassland vegetation is attributed to the adaptation of grasses to the habitat. One important adaptation of grasses in grassland vegetation is that they store nutrients and food in their roots, which doesn't get affected after a hazardous occurrence like fire etc. After the hazard, grasses sprout quickly using the stored nutrients in their roots. This is one adaptation that defines the success of grasses in a grassland vegetation rather than forest.Learn more: https://brainly.com/question/13458988?referrer=searchResults
