Use the Gizmo to estimate the age of each of the objects below For these questions, each second in the Gizmo represents 1,000 years.
Answers
Using the Half-life Gizmo, estimate the ages of the objects as follows:
Egyptian papyrus: Approximately 12,000 years
Aboriginal charcoal: Approximately 24,000 years
Mayan headdress: Approximately 6,000 years
Neanderthal skull: Approximately 36,000 years.
1. Egyptian papyrus (63% original Carbon-14 atoms):
The papyrus has undergone decay, and given its remaining Carbon-14 percentage, it can be estimated to be approximately 12,000 years old. This calculation is based on the principle that each half-life represents a reduction to half the initial amount of radioactive material.
2. Aboriginal charcoal (22% original Carbon-14 atoms):
With a lower remaining percentage, the Aboriginal charcoal is estimated to be older than the papyrus. The calculation suggests an approximate age of 24,000 years, indicating a longer time since the initial presence of Carbon-14.
3. Mayan headdress (79% original Carbon-14 atoms):
The higher remaining percentage of Carbon-14 in the Mayan headdress indicates a more recent age compared to the previous objects. The estimation using the half-life concept suggests an age of around 6,000 years.
4. Neanderthal skull (3% original Carbon-14 atoms):
The Neanderthal skull has experienced significant decay, and the low remaining percentage implies a much older age. The estimation using the Half-life Gizmo suggests an approximate age of 36,000 years.

Question:Sherri has 23 pieces of jewelry to sell. She sells the bracelets for $2 and the necklaces for $3, and earns a total of $55. If the bracelets are represented by x and the necklaces are represented by y, which of the following systems of equations can be used to calculate the number of bracelets and necklaces sold? Answer choices: A. x + y = 23, 3x + 2y = 55 B. x + y = 55, 3x + 2y = 23 C. x + y = 23, 2x + 3y = 55 D. x + y = 55, 2x + 3y = 23

Answers
The effect of species loss on the environment is researched by an ecologist in an ecosystem. Thus option C is correct.
What are biotic components of ecosystem?
An ecosystem is defined as the structural and functional unit of where the living organisms interact with each other and their surrounding and was coined by A.G.Tansley, an English botanist, in 1935.
The basic components of an ecosystem are Biotic Components and Abiotic Components, both the components are interrelated with each other by doing energy flow.
Biotic components belongs to all living components like autotrophs, heterotrophs and saprotrophs. Autotrophs or producers like plants.
Second is consumer or heterotrophs which depend on other organisms for their food, can be primary consumers, secondary consumers and tertiary consumers.
Primary consumers are herbivores, Secondary consumers can be either carnivores or omnivores. Tertiary consumers get energy from on secondary consumers.
Quaternary consumers are carnivores and Decomposers include saprophytes feed on dead and decaying matter.
Thus option C is correct.

Answer:
The correct answer is: common ancestor
Explanation:
Hello! Let's solve this!
According to the evolution of living beings, we all have an ancestor.
Depending on the branch in which the living being is, it unites with the ancestor of another.
Two different branches that never join, do not have a common ancestor. In this case, they have a characteristic that unites them, so whales and pythons have a common ancestor.
The correct answer is: common ancestor
