What kind of metabolic poison would interfere with glycolysis?

Answers

Generally metabolic poisons affecting glycolysis stop the working of the Krebs Cycle. The poison substitutes for a sugar like glucose but is not able to be metabolized and used like glucose.
Final answer:

Metabolic poisons that interfere with glycolysis include those affecting pyruvate kinase, leading to ATP production failure, and ethylene glycol, which causes metabolic and lactic acidosis.

Explanation:

A metabolic poison that could interfere with glycolysis is one that affects enzymes involved in the glycolytic pathway. For instance, compounds that impair the function of pyruvate kinase will hinder the last step of glycolysis, causing a critical reduction in ATP production, especially in red blood cells (RBCs) that rely solely on glycolysis for their energy. Another example is ethylene glycol poisoning, which leads not only to metabolic acidosis due to accumulated glycolic acid but also lactic acidosis, contributing to the inhibition of metabolic pathways.

If a lawn is fertilized and it doesn't rain, the grass often dies. why?

Answers

he reason for this is the fertilizer must be dissolved in water so the plant's roots can ingest it. It cannot be used if it stays dry and because it is a mild salt it can kill the grass if it stays in contact too long.Cause the ground needs to have moisture to keep the roots from drying up. When the roots dry up the plant dies. Thus dead grass. Water more often and you can build up a hardy grass that can go longer without the need for lots of watering.Without the rain to dilute the fertilizer, it burns the grass because it's too strong. Most fertilizer is water soluable and without the water, it's too "hot". Relevance Ya Coffee Encore Best Answer: Likely it's not enough water or too much, it's got some disease or bug or it's producing seed. Water it regularly - but not too much - that's easy. Pick off any flowering parts - that's easy. The bugs or diseases are harder - you need to diagnose it and find a solution. Does it have little spider webs? It might have spider mites. They are hard to control but you can try spraying it with a soapy solution (see link).Well, first things first. If it's wilting, you've stressed the plant. When stressed the cannabis plant can turn hermaphrodite and fertilize itself and leave you with some nasty seedy bud. Next time you try, study before you plant so you can grow a stress free plant the will produce good seedless buds.
Final answer:

Grass often dies after fertilization without rain because it cannot absorb necessary nutrients, may suffer from osmotic stress, and salt buildup can become toxic to the roots.

Explanation:

Grass often dies when a lawn is fertilized and it does not rain due to several interrelated factors. Fertilizers often contain high levels of nitrogen, which is crucial for plant growth, but without sufficient water, the grass cannot absorb these nutrients. Additionally, rain is essential because it helps dissolve and distribute the fertilizer nutrients in the soil, making them accessible to the grass roots. Without rain, the fertilizer can actually draw out moisture from the soil in a process called osmotic stress, further parching the grass. Furthermore, the lack of water after applying fertilizer can lead to a buildup of salts, which can be toxic to the grass roots, exacerbating the damage and potentially leading to the death of the grass.

When experimental results are statistically significant, this means the _____ hypothesis has been _____?

Answers

When experimental results are statistically significant, this means the NULL hypothesis has been REJECTED?

Answer:

___Null __ hypothesis has been _Rejected____

Explanation:

If the results obtained from the testing of a null hypothesis are statistically insignificant then it means that there were not enough proofs to support the null hypothesis and hence in virtue of insufficient proofs the null hypothesis is rejected.  

The meaning of significant does not implies that statistically significant null hypothesis is important. However, it simply means that statistically insignificant hypothesis have high probabilities to provides less evidence in order to support the thesis.  

The probability value of hypothesis must be less than 0.01 for a strong rejection of null hypothesis.

genetic drift leads to evolutionary change in the absence of natural selection. explain how this is possible.

Answers

genetic drift is the change in allele frequencies. even if every individual has the same opportunities to survive, reproductivity contributes to the following generation, allowing it to vary due to random chance. hope this helps :)
Final answer:

Genetic drift refers to changes in allele frequencies within a population due to random events or chance, rather than selective pressures. Events such as natural disasters (resulting in a bottleneck effect) or migrations (resulting in a founder effect) can lead to genetic drift and thus cause evolutionary changes.

Explanation:

Genetic drift refers to random changes in allele frequencies within a population. Unlike natural selection, which selects the fittest individuals and often results in a more fit population overall, genetic drift operates independently, and is often just the result of chance. For example, if only a subset of individuals reproduces by chance, and they predominantly carry a certain allele, that allele's frequency could increase within the population. This could occur even if the allele does not confer a fitness advantage.

Sometimes, a chance event like a natural disaster can also cause genetic drift. Known as the bottleneck effect, such a disaster could randomly kill a large portion of a population, dramatically altering the population's allele frequencies. The leftover population might possess a significantly different genetic composition than the original. It's important to note that these changes are due to random occurrences, and not driven by selective advantages as with natural selection.

Another example of genetic drift is the founder effect. If a small group of individuals from a population establishes a new colony, the allele frequencies of this new population may not represent the original ones. So, genetic drift can lead to significant evolutionary changes over time, even in the absence of natural selection.

C.The R group gives the amino acid unique characteristics.

Answers

C.The R group gives the amino acid unique characteristics.

The R group gives the amino acid its unique characteristics, and allows it to react with other amino acids in unique ways.

Answer:

(C).The R group gives the amino acid unique characteristics.

Explanation:

Amino acids can be defined as compounds, having carbon, nitrogen, oxygen, and hydrogen atoms. Ech amino acid is made up of a carboxylic group, an amino group, a side R chain, and a hydrogen atom.

The R group provides specific characteristics to the amino acids and amino acids are classified into three categories, on the basis of their side chain or R group:

-Amino acids having non-polar R group (such as alanine and valine)

-Amino acids having uncharged, polar R group (such as tyrosine and serine)

-Amino acids having charged, polar r group (such as lysine and glutamate).

Thus, the correct answer is option (C).

Explanation:

There are basically two hypotheses that explains the evolution of six ectomorphs  

a) When the ectomorphs were evolving the island was in contiguous state. Due to this plate tectonic movement was high that ultimately led to the division of island into six different islands which caused these ectomorphs evolve separately due to the geographical barrier.

b) Second theory could be that all ectomorphs evolved on the same island but then with the division of island, they got separated.

A low return rate for a survey is likely to result in findings that are not generalizable to the entire population.
a. True
b. False

Answers

Answer would be a. True

Answer:

True

Explanation:

Response rate is a term used to describe the provision of insights that determine whether a survey was done correctly with an accurate collection of relevant and important data for the correct completion of the survey, as well as for its application in society. This rate, therefore, refers to the number of individuals who participated in a survey divided by the number of individuals who make up the sample group. With that, we can conclude that if the response rate was low, this research is not appropriate to be applied to a population. This is because a low rate of return on a survey is likely to result in findings that are not generalizable to the entire population.

what is the main cause of earthquakes and volcanic eruptions?

Answers

Movement of tectonic plates

Final answer:

The main causes of earthquakes and volcanic eruptions are the movement and interaction of the Earth's tectonic plates, along with the release of energy as the plates shift along faults. Volcanic eruptions also occur when pressurized magma finds a way to the surface. Human activities can sometimes induce earthquakes and influence damage levels, though the fundamental causes are natural geologic processes.

Explanation:

The main cause of earthquakes and volcanic eruptions is the movement of the Earth's tectonic plates. Most earthquakes occur along faults, which are breaks in the Earth's crust where blocks of the crust move past each other. These movements can lock huge masses of rock in position for a long time before they abruptly shift, causing the ground to tremble. The driving mechanism behind these movements is the heat from the decay of radioactive elements within the Earth, and the associated tectonic activity.

Those same tectonic forces can also trigger volcanic eruptions. Magma formed deep within the Earth rises through the crust, and when pressure builds up, it can be released explosively through volcanoes. An eruption can release not just lava, but also gases, ash, and rock. Sometimes, water merging with sub-surface magma adds to the explosive force of eruptions, as in the case of the 1815 eruption of Mount Tambora in Indonesia.
