What are 2 pieces of evidence that help approximate the age of earth?
How do those piece of evidence help scientists?
Help please this is do Tonight!!!
I will make brainlist!!
Answer: 1. By dating the rocks in Earth's ever-changing crust, as well as the rocks in Earth's neighbors, such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years. Related: How Big is Earth? 2. Scientific evidence relies on data, and it is crucial for researchers to ensure that the data they collect is representative of the “true” situation. This means using proved or appropriate ways of collecting and analysing the data and ensuring the research is conducted ethically and safely. Fossil evidence shows the changes in lineages over millions of years, such as in hominids and horses. Studying anatomy allows scientists to identify homologous structures across diverse groups of related organisms, such as leg bones. Vestigial structures also offer clues to common ancestors.
Explanation:
Answer: There are many different ways we can determine the earth's age. 2 pieces evidences that help apporximate the age of the earth is the dating of the rocks and fossils. Also dating the rocks in Earth's neighbors, like the moon and visiting meteorites.
Scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years
Explanation: if you look and date the rocks in the earth's crust and the moon and meteorites that could give us a date of how old the earth is becuase the rocks and fossils have been here for a long time.

Three functions of the eye help!!!!!
Explanation:
The eye receives oxygen through the aqueous. Its function is to nourish the cornea, iris, and lens by carrying nutrients, it removes waste products excreted from the lens, and maintain intraocular pressure and thus maintains the shape of the eye. This gives the eye its shape. It must be clear to function properly.
Answer:
These layers lie flat against each other and form the eyeball.
The outer layer of the eyeball is a tough, white, opaque membrane called the sclera (the white of the eye). ...
The middle layer is the choroid. ...
The inner layer is the retina, which lines the back two-thirds of the eyeball.

¿Qué impacto tendría que los microorganismos en el ciclo del carbono y nitrógeno no cumplieran en su función?
Answer:
Ver explicación
Explanation:
Los microorganismos son muy importantes en el ciclo del carbono porque descomponen la materia orgánica. Esta descomposición de la materia orgánica se llama descomposición. Este proceso devuelve carbono al suelo. Si estos organismos no desempeñan su papel, el ciclo del carbono estará incompleto porque el carbono no se devuelve al suelo como materia orgánica.
En el ciclo del nitrógeno, las bacterias nitrificantes atrapan y fijan el nitrógeno atmosférico en el suelo, mientras que las bacterias desnitrificantes convierten los nitratos del suelo en nitrógeno. Las actividades de estos microorganismos mantienen el equilibrio del hidrógeno en el ciclo del nitrógeno.
What are the differences between animal cells and plant cells
Answer:
Explanation:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
Answer:Las células vegetales tienen una pared celular, así como una membrana celular. En las plantas, la pared celular rodea la membrana celular. Esto le da a la célula vegetal su forma rectangular típica. Las células animales solo tienen una membrana celular, y carecen de pared celular.
How is the cytoplasm divided between the two cells that result from mitosis in plant cells? In animal cells?
Answer:
The contractile ring shrinks through the center of the cell, evenly dividing the cytoplasm between the two halves. This indicates that cytokinesis is completed and the cell has been replicated.

Explanation:
You are part of a small group of humans rocketed at “warp speed” to Planet X, without any books, weapons, or technology. Planet X has no ozone layer to protect its surface from cancer-causing ultraviolet radiation, but native plants and animals have evolved to live safely there. Below the surface, the planet has a network of underground tunnels, just a meter high, which are inhabited by carnivorous predators.
Write 3 paragraphs using the vocabulary words we discussed today in class about how descendants of the group of humans would look and act after evolving for 100,000 years on Planet X.
Use these vocabulary words:
• Evolution
• Mutation
• Non-random Mating
• Gene Flow
• Genetic Drift
As you worked down the dichotomous classification key to identify sharks, did you go from general to specific characteristics or from specific to general characteristics? Explain your answer using four characteristics that were used in the shark key.
When constructing a dichotomous key, we should start with general characteristics and then move to more specific characteristics. A dichotomous key lists an organism's structure and behavior so it may be recognized through elimination.
What are four characteristics that are used in the shark key?When attempting to categorize an organism, scientists frequently make use of a dichotomous key. A dichotomous key is a listing of specific features, such as structure and behavior, in such a way that an organism may be identified through a process of elimination. Examples of dichotomous keys include the following:
The shape of the body, the number of gill slits, the position of the mouth, and the shape of the caudal fins are the dichotomous keys for identifying sharks. Other features include the length of the dorsal fins or the number of dorsal fins, the presence or absence of pelvic fins and the shape of the skull.

What conclusion can you make regarding how humans affect biodiversity? Is evidence from the graph to support your answer
Answer:
Decrease population of staghorn coral and spotlight parrot fish.
Explanation:
Humans greatly affects biodiversity by decreasing the population of most of the organisms due to its activities. Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.
The following are all concepts of natural selection EXCEPT: *
1. Variations can be inherited.
2. A limited number of individuals born will survive to adulthood.
3. There is a struggle for existence among offspring of the same species.
4. All organisms of a species will survive.
Answer:
2 A limited number of individuals born will survive to adulthood.
Explanation:
Answer:
4. All organisms of a species will survive
Explanation:
4 is the complete opposite of natural selection.
Natural selection basically says that certain members of the species will die off and the more fit ones will survive and produce stronger, better-adapted offspring.
Why are the surface winds moving toward the area where air is moving up?
Why are cities more likely to
flood than out in the country?
Answer:
As a result, water runs off of the concrete structures, sometime known as pluvial flooding or urban flooding. In urban areas, with rapid increase in impermeable surfaces and urban development, the likelihood of flooding has increased.

Why are nonnative species a threat to biodiversity?
They often use up resources that other organisms need.
They are not able to successfully breed in the wild
They release pollution into many environments. l
They easily contract and spread diseases to other organisms.
Answer:
The non-native species are the prime threat to the surroundings as they can modify habitats and change the ecosystem services and function, and may replace or crowd-out the local species. The non-native species are considered as the second-ranked major threat to biodiversity after habitat destruction like deforestation.
Answer:
If you're only allowed to have one answer: They often use up resources that other organisms need.
If you can have multiple, then :
They often use up resources that other organisms need.
They easily contract and spread diseases to other organisms.
