Suppose you found a rock, and through testing found out that it had just as much lead-206 as uranium-238 in it. How old would you conclude the rock to be?
Answer:
The answer is below
Explanation:
Let m be the mass of each of lead-206 and uranium-238 found in the rock. The radioactive decay is given as:
[tex]U_t=U_oe^{-\lambda t}\\\\U_t=number\ of\ undecayed\ U238\ after\ time \t,\\U_o=number\ of\ undecayed\ U238\ initially,\lambda=decay\ constant\\\\But\ U_o=U_t+Pb_t\\\\U_t=U_t+Pb_t(e^{-\lambda t})\\\\e^{-\lambda t}=\frac{U_t}{U_t+Pb_t} \\\\e^{\lambda t}=\frac{U_t+Pb_t}{U_t} \\\\e^{\lambda t}=1+\frac{Pb_t}{U_t}[/tex]
half life of uranium-238 = 4.468 * 10⁹ years
λ = 0.693 / half life = 0.693 / 4.468 * 10⁹ years = 0.1551 * 10⁻⁹
[tex]n_{Pb_t}=\frac{m}{206} \\\\n_{U_t}=\frac{m}{238}\\\\1+\frac{\frac{m}{206}}{\frac{m}{238}}=e^{\lambda t} \\\\e^{\lambda t} =2.1553\\\\ln(e^{\lambda t} )=ln(2.1553)\\\\\lambda t=0.7679\\\\t=\frac{0.7679}{\lambda} \\\\t=\frac{0.7679}{0.1551*10^{-9}} \\\\t=3.43*10^9\ years[/tex]
Name one way in which soil depends on a biotic factor.
Answer:
Soil is composed of both biotic—living and once-living things, like plants and insects—and abiotic materials—nonliving factors, like minerals, water, and air. Soil contains air, water, and minerals as well as plant and animal matter, both living and dead.
Explanation:
Abiotic and biotic elements, as well as other components, make up the complex and dynamic system known as soil. Living elements of the soil, such as plants, animals, and microorganisms, are referred to as biotic factors.
What is the way to create a complex and a dynamic system ?A complex and dynamic system is created by the interactions between these living elements and the soil's abiotic elements, such as water and minerals. The cycle of nutrients is one way that soil is dependent on a biotic component.
The process of moving nutrients through the soil and its biotic elements is known as nutrient cycling. When plants and other living things die or are consumed by other living things, they return nutrients from the soil to it.
This round for soil fertility and general soil health to be maintained, nutrient uptake and release are crucial. As they decompose organic matter and release vital nutrients into the soil, soil microorganisms also play a significant part in this process.
Soil wouldn't be able to support the growth of plants and other organisms without this nutrient-cycling process.

If an organism was able to survive the increase in airborne toxins, what traits will their offspring carry? What about the next generation?
Answer:
If an organism is able to survive the increase in airborne toxins and reproduce, there is a high chance that their offspring will also be able survive in airborne toxins, although some may not. But all the organisms that can survive and reproduce will produce more and more organisms that are able to survive from an increase in airborne toxins.

Explain how the availability of resources in the environment is linked to exponential growth of a species
Answer: Exponential growth occurs when resources in the environment are abundantly available to a species.
Explanation: When a food source amount drops, so does the survival rate of the predator that eats that specific food source. When a food source grows too abundantly at too fast a rate, predators increase in numbers.

A. tRNA delivers DNA code to the ribosome and mRNA delivers amino acids to the ribosome
B. mRNA delivers DNA code to the ribosome and tRNA delivers amino acids to the ribosome
C. tRNA delivers DNA code to the nucleus and mRNA delivers proteins to the ribosome
D. mRNA delivers DNA code to the nucleus and tRNA delivers proteins to the ribosome
Answer:
The right answer is D.
Explanation:
The messenger ribonucleic acid, messenger RNA, or mRNA is a transient copy of a portion of the DNA corresponding to one or more genes. mRNA is used as an intermediate by cells for protein synthesis. Jacques Monod, François Jacob, and their collaborators issued and showed the concept of messenger RNA in 1960.

Answer:
The Gulf Stream is caused by a large system of circular currents and powerful winds, called an oceanic gyre.
As the warm water comes in, colder, denser water sinks and begins moving south—eventually flowing along the bottom of the ocean all the way to Antarctica.

Could artificial selection occur without natural variation?
Answer:
In artificial selection, nature provides the variations, and humans select those they find useful. No because inherited variation occurs out of everything or occurs in all breeding.
Explanation:
A farmer uses DDT to kill insects in his field. The first year nearly all of the insects were killed. By the fourth year, however, nearly all of the insects survived the DDT treatment. Explain the process of natural selection in this population of insects. Include these words - mutation, phenotype, variation, resistance, adaptation, and differential survival.
Answer:
Explanation:
Selection is the greatest force that alters gene frequency and brings about variation that is evidence in a population. There are both natural and artificial selection.
Mutation is one of the force that alters population frequency it is an heritable change that is sudden and occur in the gene, it can be induced or caused naturally.
The insect survived the DDT used because over the years they have build immunity and resistance against the chemical, they now mutate and produce gene that becomes resistance to the chemical and now adapted or adaptable to the environment. Natural selection helps in the continuous perpetuation of the new phenotype and a new differential survival rate.

Distinguish between breathing and respiration.
As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
➜ Breathing:
The process of obtaining oxygen and releasing carbon dioxide is called breathing.It is a physical process.It takes place in the lungs.It utilises energy from the food.Respiration:
The process of releasing energy from food is called respiration.Heterotrophs are directly or indirectly dependent on autotrophs.It takes place in the lungs as well as in mitochondria.It releases energy from the oxidation of simple food.Help please ill mark brainliest!

Explanation:
if wrong then sry
Answer:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. During this process huge amount of energy is created.
