The Punnett square is not found here but, according to data, these genetic traits involve the expression of two different genes (proportion 1/16 in double recessive).
What is a Punnett square?A Punnett square is a diagram used in genetics to calculate the genotypic proportion from a given genetic cross.
Two different genes may generate 16 genetic (allelic) combinations in a Punnett square.
Moreover, fur color and eye color are phenotypic traits that depend on the recessive-dominance allele relationships received in offspring.
In conclusion, the Punnett square is not found here but, according to data, these genetic traits involve the expression of two different genes (proportion 1/16 in double recessive).

(the images go with part A and B)
Part A :
In a wooded area in North Carolina, two teenagers discovered an abandoned pistol and a few other items that led them to call 911. Crime scene personnel and investigators processed the scene and found human remains along with other items. They then photographed all the evidence at the crime scene. Analyze the photographs of the skeletal remains and other items and determine the gender and age of the victim.
Part B: Examine visible trauma marks and other evidence found at the crime scene and make a preliminary hypothesis on the cause and manner of death.
Part C:Research four databases and describe how these databases would help you investigate this case.
From the photographs presented, investigation reveals that the gender and age of the victim are:
Age: Elderly, at least 40 years old;Gender; Female. This is clear from the hip and the shoe type discovered as the scene.What is the preliminary hypothesis on the cause and manner of death?The hypothesis or cause of death is a gun shot to the head.

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.
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.

Which of the following best describes why in general there are more hares in the ecosystem than foxes.
In 1945 there was a major event that caused the number of hares to dramatically increase. That is why there continues to be more hares than foxes here.
Hares are a lot smaller than the foxes, so more of them can fit into different niches. They can hide better in all of the bushes and behind rocks.
This is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to support the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development
Answer:
C
Explanation:
The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development.

What is the charge of the
electrical impulses sent from
stimuli?
A. Extremely positive
B. Exactly neutral
C. Negative
D. It depends on the location.
The charge of the electrical impulses sent from stimuli is extremely positive. Thus, the correct option is A. The net charge of such electrical impulses is positive because of the positively charged ions of the Na+.
What is an electrical impulse?An electrical impulse may be defined as a nerve impulse that contains an electrical signal which travels throughout the body by the axon terminal.
In the resting potential state, the potential difference is -80mV, while after reaching the electrical impulse it changes to +40mV. This happens due to an electrical imbalance between sodium and potassium influx and efflux.
Therefore, the correct option is A.

How does water cycles involve biotic and abiotic factors?
Answer:
This recycling process involves both the living organisms (biotic components) and nonliving things (abiotic factors) in the ecosystem. Through biogeochemical cycles, water and other chemical elements are constantly being passed through living organisms to non-living matter and back again, over and over.
Explanation:

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.

Evaluate the information in order to construct an argument about the removal of the Conowingo Dam as a solution to address the American Eel
population issue. Your argument should:
• Clearly state your position - either in favor of removing the dam or opposed to its removal as a solution to the problem
• Include evidence-specific environmental, social, and economic costs and benefits related to your position
• Use scientific reasoning to explain how the costs and benefits you have selected support your position.

Based on the hypothesis (Big Bang theory) that the universe is expanding, an analysis of light wave would indicate: A. a decrease in frequency and a red shift.
What is a redshift?A redshift can be defined as a displacement (shift) of the spectral lines of an astronomical (celestial) object toward longer wavelengths and a corresponding decrease in frequency, as a result of the Doppler effect.
Basically, a redshift occur when observing an astronomical (celestial) object from planet Earth because it's receding (moving away) from planet Earth.
