The half-life of uranium-328 is about 4.5 billion years. After four half-lives have passed, what fraction of the original sample will be left?
Uranium-238 decays very slowly with a half life of 4.5 billion years. what percentage of a sample of uranium-238 would remain after 13.5 billion years?
The mass of Uranium halves every 4.5 billion years, so 13.5 billion years= 3 half-lives.
[tex]M=M_{0}[/tex] × [tex](\frac{1}{2} )^n[/tex]
Is the equation that describes the decay, where [tex]M^0[/tex] is the initial mass and [tex]n[/tex] is the number of half-lives passed.
So if 3 half-lives have passed:
[tex]M=M_{0}[/tex] × [tex](\frac{1}{2} )^3[/tex]
[tex]M=M_{0}[/tex] × [tex](\frac{1}{8} )[/tex]
[tex]M= \frac{1}{8} M_{0}[/tex]
So there will be 1/8 of the original mass left after 13.5 billion years, or 12.5% of the mass left.
DNA is directly inherited from an organism's parents, via their gametes, which are produced by the process of ____________________. Thus, if a person has phenylketonuria, they have inherited genetic information that has lead to the production of a dysfunctional protein, specifically a(n) _________________ that normally breaks down phenylalanine.
DNA is directly inherited from an organism's parents, via their gametes, which are produced by the process of Gametogenesis. Thus, if a person has phenylketonuria, they have inherited genetic information that has lead to the production of a dysfunctional protein, specifically a(n) enzyme that normally breaks down phenylalanine.
What is phenylketonuria?Phenylketonuria is a rare genetic disease characterized by the presence of a mutation responsible for altering the function of an enzyme in the body responsible for converting the amino acid phenylalanine into tyrosine, which leads to the accumulation of phenylalanine in the blood, which in large concentrations is toxic to the human body.
With this information, we can conclude that DNA is inherited directly from the parents of an organism, through its gametes, which are produced by the process of Gametogenesis. So, if a person has phenylketonuria, they have inherited genetic information that led to the production of a dysfunctional protein, specifically an enzyme (n) that normally breaks down phenylalanine.

A mutation occurs during protein synthesis. How will the protein produced be affected? A. Since the mutation causes a new code for a better amino acid, the protein will still function normally. B. Since the mutation causes a new code for the same amino acid, the protein will still function normally. C. Since the mutation causes a new code for a better amino acid, the protein will be more powerful while performing its function. D. Since the mutation causes a new code for the same amino acid, the protein will be more powerful while performing its function.
Answer:
A mutation during protein synthesis may not affect the protein since the mutation causes a new code for the same amino acid, the protein will still function normally.
Explanation:
Protein synthesis depends on the transcription of DNA to RNA, and on the sequence of nucleotides in the chain, determining the triplets or codons that encode a specific amino acid.
In protein synthesis, when a mutation alters the codon, changing one nucleotide for another, it is possible that the mutation does not alter the amino acid and the protein functions correctly. This is because an amino acid can be encoded by several codons, as occurs with leucine, which is encoded by CUU, CUC, CUA and CUG.
The other options are not correct because one mutation does not give better amino acids or more powerful proteins.

The distinct characteristics of different cell types in a multicellular organism are produced mainly by the differential regulation of the genes.
What is gene regulation?Genes are responsible for the synthesis of protein molecules in the cell.
All the cells of a living organisms contain the same sequence of genes, however, they differ in the way they are expressed.
This makes cells exhibit different characteristics in the same living organism.
Therefore, the distinct characteristics of different cell types in a multicellular organism are produced mainly by the differential regulation of the genes.

En una situación experimental, tras permanecer en ayunas, tres personas ingieren: la primera (A) una ración de celulosa, la segunda (B) una ración de glucosa y la tercera (C) una ración de almidón. Compare la rapidez con la que suba la glucemia (nivel de glucosa en sangre) de las tres personas. Razone la respuesta.
Answer:
La respuesta correcta es: "El orden de rapidez en el sube la glucemia es el siguiente: (B) una ración de glucosa, (C) una ración de almidón y (A) una ración de celulosa".
Explanation:
La rapidez a la que sube el nivel de glucosa en la sangre depende del alimento que estemos ingiriendo. En este caso, el ingerir una ración de glucosa será lo que aumente el nivel de glucemia más rápidamente dado que no requiere ningún procesamiento digestivo. En segundo lugar será el almidón, el cuál debe ser degradado por la enzima amilasa para tener acceso a la glucosa. En último lugar será la celulosa, dado que no tenemos las enzimas necesarias para digerirla y se requiere la ayuda de microorganismos para hacerlo.

How does a hot day affect enzyme activity during photosynthesis?
Answer:
At higher temperatures, more collisions occur so the rate of reaction increases. However, extremely high temperatures disrupt the shape of the active site, which will reduce itsactivity, or prevent it from working. Theenzyme is now denatured . Enzymestherefore work best at their optimum temperature.
What are two ways that different species can divide up resources?
Answer:The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Is there a systematic relationship between period and radius for the planets? How do you know this?
Answer:
We suggest the existence of a correlation between the planetary radius and orbital period for planets with radii smaller than 4 R⊕. Using the Kepler data, we find a correlation coefficient of 0.5120, and suggest that the correlation is not caused solely by survey incompleteness.

The rabbit population in an ecosystem has grown past it's carrying capacity. What are two things that may happen naturally to bring the rabbit population back under control and how would these things control the population? (Must be at least 2 COMPLETE sentences
Answer:
One of the two things that could bring its population back down is lack of food, This is because due too the boom of the rabbit population their food sources will be eaten at a much faster rate until it overtime runs out. Another one is more predators, because of more rabbits more predators will be drawn too the area and help with population control by eating/killing them.

Answer:
Life Span;The the period between birth and natural death of an organism is called life span.Life span varies from less than one day to more than 4000 years. Life span are not related to size or complexity of the organisms.Crows and parrots are of equal size. Crow has a life span of only 15 years while parrot lives for about 140 years.Similarly, Mango tree lives for about 200 years while Peeepal (Ficus religiosa) has a life span of about 2500 years.Banyan tree (Ficus bengalensis) spreads over a very large area but does not live beyond 500 years.

why you SHOULD NOT drink salt water if stranded at sea.
Answer:
Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly.
Answer:
The salt water will make you go lose your mind,and it will dehydrate you.
If I were measuring the pH at varying distances along a stream to test the impact on pH of the factory upstream. I would choose to measure the water above the factory which would represent which part of an experiment (control, independent, or dependent) Circle one.
Answer:
Dependent variable
Explanation:
The dependent variable in an experiment is the variable that the experimenter measures in an experiment. The dependent variable responds to changes made to the independent variable.
In this case, the pH of a stream is being measured at varying distances. If one is to measure the pH of the part of water above the factory, the pH being measured represents the DEPENDENT VARIABLE in the experiment.
