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]

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.

Answer:

Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.

Explanation:

Gene flow within the population increases the genetic variability in the wolf population variation can be seen.

Gene migration is another name for gene movement. The movement of genetic material from one group to another is referred to as gene flow.

Through migration, gene flow can occur between two populations of the same species and is mediated via vertical gene transmission from parent to offspring and reproduction.

Any movement of people and the genetic material they carry from one community to another is referred to as gene flow, often known as migration.

Therefore the movement of genetic material from one population to another is known as gene flow.

Explanation:

The abundance of volcanoes and earthquakes along the Ring of Fire is caused by the amount of movement of tectonic plates in the area. Along much of the Ring of Fire, plates overlap at convergent boundaries called subduction zones. That is, the plate that is underneath is pushed down, or subducted, by the plate above.5

Answer:

the results will likely be recording and could inspire a new hypothesis.

Explanation:

The initial rise in the line of the graph is an example of population growth

as a result of increase in food supply.

This is defined as the increase in the number of organisms in a given area

which is usually over a period of time.

Increase in food supply leads to organisms having enough nutrients

required for survival and basic biochemical activities such as reproduction.

This makes option D the most appropriate choice.

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.

Answer:

D. Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.

Explanation:

Photosynthesis requires solar energy from the sun, which energizes electrons and allows for glucose to be created.

In cellular respiration, glucose provides chemical energy when it is broken down. This creates ATP energy for the cell to use.

So, the correct answer is D.

Answer: Disinfectant is a chemical formulation which may include biological components used to reduce the population of a microbe from a living or dead surface.

Explanation:

The plant tissue is treated with a disinfectant before culturing it and growing new plants. This is done to remove dirt, dust, foreign particles like pollen, microbes from the plant tissue surface or from plant part. This help in growth of disease free and contamination free plants. The culture can be utilized for different cycles of plant growth as it remains free from any kind of contamination.

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.

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.

The characteristic that is shared by both primary and secondary consumers is that they gain energy by eating other living things. Therefore, option D is correct.

The primary consumers are the organisms that devour the producers. They are numerous and often modest in size. Herbivorous animals are the primary consumers (vegetarians). The organisms known as secondary consumers are carnivores that consume the primary consumers. Secondary consumers are consumed by tertiary consumers.

Herbivores, carnivores, omnivores, and decomposers are the four different categories of consumers in ecology.
