A scientist wants to determine the age of a rock. The rock contains an index fossil and an ancient relative of a living organism. Which is more useful for dating the rock, and why?
Answer: Ancient Relative of a living organism
Explanation: Ancient Relative because by using the index fossil, you are also using the law of superposition. This law does not give you an accurate/specific date but instead the order they are in (i.e me saying i am older than my siblings compared to me saying i am 2 years older than them). By using an ancient relative of a living thing then we can see its phylogenic tree and measure around how old it is. Fossils also hold carbon and chemicals in there bones which allows us to use carbon dating. Carbon dating is an accurate way of measuring age.

Carefully and completely answer the "essential question" of this activity. Use
complete sentences and details from the model to explain your position.
Essential Question: What is the relationship between photosynthesis
and respiration?
*Zoom in to the picture for a better view
Answer:
I. Examine Details
1. In what cell organelle does photosynthesis occur? cellular respiration?
Photosynthesis occurs in the chloroplast, while cellular respiration occurs in the mitochondria.
2. What are the three things needed for photosynthesis? Highlight them on the diagram in green.
Sunlight, carbon dioxide, and water
3. What are the two products of photosynthesis? Highlight yellow.
Glucose and oxygen
4. What are the two things needed for cellular respiration? Highlight blue.
Glucose and oxygen
5. What are the three products of cellular respiration? Highlight purple.
Carbon dioxide, water, and ATP
6. What things are recycled (used over and over again) during photosynthesis and respiration?
Carbon dioxide, water, oxygen and glucose
II. Apply (what you already know)
7. Sketch a model of typical plant cell and identify the mitochondria and chloroplasts.
8. What will happen to plants that are kept in the dark?
Plants will die since plants need daylight to deliver food. If there is no admittance to sunlight, the Light Dependent response will not happen.
9. What will happen if you forget to water your plants?
The plants will die since water is a necessary reactant photosynthesis.
10. What happens to animals that are deprived of oxygen?
Those animals will not be able to perform cellular respiration.
III. Big Ideas
11. One hypothesis regarding the extinction of dinosaurs is that a meteor hit the earth causing an explosion so powerful that dust blocked out the sun. Consider the model above and explain why would this have caused a mass extinction?
Obstructing the Sun would cause the powerlessness for essential makers, for example, plants, to go through photosynthesis, in this way not creating its own food fundamental for development and energy.
12. When you walk your dog, you are using energy from the sunlight to power this activity.
Explain. Sunlight gives the energy to essential makers to make their own food, using the carbon dioxide and delivering oxygen gas as a result of photosynthesis. The oxygen that is delivered into the environment is taken in by life forms as a reactant in respiration. Oxygen allows for ATP creation. The ATP is the substance energy structure that is needed to convey all cell processes such as walking your dog.
13. Carefully and completely answer the "essential question" of this activity. Use complete sentences and details from the model to explain your position.
Essential Question: What is the relationship between photosynthesis and respiration?
Photosynthesis and respiration are related since the reactants of photosynthesis are the products of cellular respiration, and vice versa. For example, the reactants of photosynthesis are energy, carbon dioxide, and water, while the products are oxygen and glucose. The reactants of cellular respiration are oxygen and glucose, while the products are energy, carbon dioxide, and water.

What is cancer? Is cancer only one disease?
How does cancer affect the cell cycle and the growth of cells? How is this process similar to or different from how an infectious disease affects cells?
How do genes play a role in cancer progression?
Are there any environmental or pathogenic factors that can cause cancer?
How does cancer progress in the body? Why is cancer difficult to treat in the later stages?
What do the terms stage and grade mean in the context of cancer?
What current treatments exist for cancer?
What treatments are on the horizon?
What are the challenges of treating or curing cancer?
Answer:
- Cancer isn't a single disease. The term cancer encompasses more than 200 diseases all characterized by the uncontrolled proliferation of cells.
- Cancer cells also fail to undergo programmed cell death, or apoptosis, under conditions when normal cells would (e.g., due to DNA damage). In addition, emerging research shows that cancer cells may undergo metabolic changes that support increased cell growth and division 5start superscript, 5, end superscript.
Genetic Changes and Cancer
Genes carry the instructions to make proteins, which do much of the work in our cells. Certain gene changes can cause cells to evade normal growth controls and become cancer. For example, some cancer-causing gene changes increase production of a protein that makes cells grow.
- People who have certain jobs such as; painting, construction, pesticide and petroleum workers have an increased risk of cancer. Many studies have shown that exposure to asbestos, benzene, benzidine, cadmium, nickel, arsenic, radon and vinyl chloride in the workplace can cause cancer.
- Metastatic cancer causes most cancer deaths, but exactly why it is so difficult to treat is not precisely understood. Metastatic tumors often acquire additional genetic changes from those in the primary tumors that spawned them, and these genetic characteristics may cause them to resist standard treatments.
- Treating cancer is further complicated due to the lifestyle and attitude of patients, the different physiology of people and the rate their bodies will metabolise drugs, the blood supply to the tumour affecting the drug getting into the tumour, the tumour physiology and the fact that the tumour can continue to change.
- The stage of a cancer describes the size of a tumour and how far it has spread from where it originated. The grade describes the appearance of the cancerous cells.
- Cancer treatment options include:
Surgery. The goal of surgery is to remove the cancer or as much of the cancer as possible.
Chemotherapy. Chemotherapy uses drugs to kill cancer cells.
Radiation therapy. ...
Bone marrow transplant. ...
Immunotherapy. ...
Hormone therapy. ...
Targeted drug therapy. ...
Cryoablation.
- Cancer treatments on the horizon
Current treatments. There are many treatments currently available to treat different types of cancers. ...
Biological therapy. ...
Haematopoietic growth factors. ...
Stem cell and bone marrow transplants. ...
Individual hormonal drugs. ...
Monoclonal antibodies. ...
Surgery. ...
Clinical trials.

MY INTRODUCTION ARE ANSWERS TO ALL YOUR QUESTIONS (your question is too long)
Describe an approach for understanding global systems and the changes they undergo
IN UR OWN WORDS
ill give brainliest if its in ur own words
50 points :)
Answer
To understand the global systems and the changes they undergo in a better way, we can use a model to represent the various ecological processes that occur within the biosphere. One example of a model that we can use is the earth systems model. It can show the causes and effects of global change to provide us with insights and learning about the global system as a whole.
Explanation:
Answer:
To be able to understand global systems and their changes first we must survey them before and relook at the systems and analyze how they have changed and what caused these changes.
