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?
Answers
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.

The amount of available ______ limits the number of trophic levels in a community. please help!!!
Answers
Explanation:
Decrease in energy at higher trophic levels limits the number of trophic levels in a food chain. When the number of links keep increasing, the amount of energy available decreases, as only 10% of energy gets transferred from one trophic level to the next.
The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels.
hypothesis for protein synthesis gizmo
Answers
Answer:
this link is the answer https://www.scribd.com/document/487194021/protein-synthesis-gizmo
One possible hypothesis for the Protein Synthesis Gizmo could be: "If the availability of amino acids is increased, then the rate of protein synthesis will also increase."
This hypothesis suggests that the amount of protein synthesized by the cell is directly influenced by the availability of amino acids, which are the building blocks of proteins. Amino acids are monomers of protein.
By increasing the supply of amino acids, it is expected that the cell will have more resources to engage in protein synthesis. It causes an increase in the rate at which proteins are produced.

which level of an energy pyramid has the least amount of food energy?
Answers
Answer: Tertiary consumers receive 10% of the energy available at the secondary level (0.1% of the original energy). As a result, tertiary consumers have the least amount of energy and are therefore at the top of the pyramid (the smallest part).

what change to a property of a light wave would make the light wave appear dimmer?
a. reducing the waves frequency
b. reducing the waves amplitude
c. increasing the waves amplitude
d. increasing the waves frequency
Answers
Answer:
B.
Explanation:
The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.
The brightness of light is related to intensity or the amount of light an object emits or reflects.
What is brightness?Brightness depends on light wave amplitude, the height of light waves. Brightness is also somewhat influenced by wavelength.
When a source appears to be reflecting or radiating light, it is said to be bright. It's critical to comprehend the terminology and technology utilized in the lighting sector.
Lumens are a unit of measurement for light output from a bulb. A light's lumen count indicates its brightness; a lower lumen count indicates a dimmer light. Weight is like bananas, To milk are gallons, Lumens enable you to purchase the desired amount of light.
Therefore, The brightness of light is related to intensity or the amount of light an object emits or reflects.

A model cell with damaged DNA was created to explain the importance of checkpoints in a cell cycle. The G2 checkpoint accidentally failed to work during experimentation. What do you think is the likely consequence of this failure?.
Answers
Answer: the consequenc of this failure is The cell continued to divide uncontrollably to create more damaged cells Which can lead to deadly diseases like cancer, breast cancer and many more
If the G2 checkpoint accidentally failed, then the cell will enter into division. The likely consequence of this failure is that the cell proliferates in an uncontrolled manner.
The cell cycle is controlled by checkpoints that regulate the progression through different phases of the cell cycle.
The G2 checkpoint acts to prevent the entry in mitosis of cells that have damages in its genetic material (DNA) in order to repair it.
When the cell undergoes failures in the G2 checkpoint control, the cell divides in an uncontrollable manner and thus generate groups of damaged cells (e.g., a tumor).

Answers
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.

Essential Question: What is the relationship between photosynthesis
and respiration?
*Zoom in to the picture for a better view
Answers
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.

Answers
Answer:The behavior of the both liquid and gas will be different in some aspect and same in the other, lets see how:
Explanation:
As we have studies that liquids donot have a specific shape but do have a specific volume. So when the liquid will be transferred from small to large container, it will adapt the shape of new container but its volume will stay same as it was in old container.
On the other hand, about gases, we know that they donot have specific shapes and the volume is also not definite and depends on the shape of container. Therefore, the gas atoms will freely move in the container and the volume will be changes in large container.
