From the illustration, it can be said that the age of the rock layer is the same in the four locations of index fossil 1.
Age of fossilIt is a measure of how long a material has been fossilized.
Thus, if a rock layer contains a fossil and another similar rock layer does not have the fossil, one can conclude that the ages of the rock layers are different.
Only index fossil 1 is found in all the four locations as shown in the image. Hence, one can as well infer that the rock layers in all these four locations are of the same age.

What is a feedback mechanism?
Answers
What is a feedback mechanism?
A feedback mechanism is a physiological regulation system in a living body that works to return the body to its normal internal state, or commonly known as homeostasis. In nature, feedback mechanisms can be found in a variety of environments and animal types. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
Examples:
Menstrual cycle. At the beginning of the menstrual cycle, the ovaries release the hormone estrogen. The estrogen acts as a stimulus for the positive feedback loop. ...Childbirth. Figure: Normal childbirth is driven by a positive feedback loop.
As human populations have changed over the years, people have altered the course of rivers and other waterways to better suit their needs. one approach has been through the damming of certain rivers. over time, many people question whether this effort has been beneficial. what are the negative impacts of damming a river that are being assessed?
dams allow more water to flow into nearby reservoirs, increasing the chances of disease transmission.
dams cause increases in salmon populations because more water is available for them to live in.
dams reduce salmon stocks, which reduces revenue and overall whale populations.
dams allow for invasive species to move around more easily, which reduces biodiversity.
Answers
Dams allowing more water to flow into nearby reservoirs thereby increasing the chances of disease transmission is its negative impact and is denoted as option A.
What is a Dam?This is a form of barrier which restricts the flow of water for different reasons such as reservoirs, electricity generation etc.
Since the water flows to reservoirs in close proximity, it increases the risk of disease transmission such as malaria etc.

What is aquarium?
An aquarium (plural aquariums or aquaria) is a vivarium, usually contained in a clear-sided container (typically constructed of glass or high-strength plastic) in which water-dwelling plants and animals (usually fish).
According to this question, the aquarium contains water, plants and fish. The glass of the aquarium is transparent and allows the passage of light. Plants are unique set of organisms that have the ability to produce their own food (organic molecule) using the energy from light which they absorb via the Chlorophyll pigment in their Chloroplast. This process carried out by plants is called PHOTOSYNTHESIS.
The amount of carbon in form of carbondioxide (CO2) decreases when the light was switched on in the aquarium due to the process of photosynthesis carried out by the plants.

Explanation:
The images show two different types of Galapagos tortoises that scientists believe descended from the same species. The first type (left) are found on islands that have high vegetation and few grasses. The second type (right) are found on an island that has large amounts of grasses and low-lying shrubs. What explains the type of turtle found on the islands with high vegetation?
A.
The environment triggered a gene mutation in neck length in order to help the turtle survive.
B.
Mutations are random, so it is by chance that turtles with longer necks live on these islands.
C.
Turtles with genes for long necks had a better chance of surviving to reach reproductive age.
D.
Turtles with short necks completely lacked adaptations for finding food, so they died off.
Answers
Turtles with genes for long necks had a better chance of surviving to reach reproductive age due to ability to reach the food source.
What type of turtle survive on the Island?Turtles with genes for long necks had a better chance of surviving to reach reproductive age because the long neck enables the turtles to reach the food source that is present on a certain height. So they are able to survive and complete its life cycle.
