Answer:
Genotype gray bunnies: GG
Genotype white bunnies: WW
Genotype gray and white bunnies: GW
Explanation:
In diploid species (2n), organisms receive one gene copy (allele) from each parent. Codominance is a relationship that occurs when both alleles of the same gene show dominance. In consequence, the expression of both alleles in heterozygous individuals results in a new phenotype. In this example, the expression of G and W alleles results in a gray and white phenotype. Examples of codominance include individuals with type AB blood group in humans or the roan coat color in horses.

What is the pattern of energy transformation from light switch to light bulb?
a. Potential Energy, Thermal Energy, Light Energy
b. Kinetic Energy, Mechanical Energy, Potential Energy
c. Electrical Energy, Heat Energy, Light Energy
d. Mechanical Energy, Electrical Energy, Radiant Energy, Thermal Energy
Answer:
The correct answer is - option C. Electrical Energy, heat energy, light energy.
Explanation:
The transformation of energy from the light switch to the light bulb starts with the electrical energy to the heat or thermal energy and also generates the light energy which lights the bulb.
The amount of electrical energy is equal to the amount of light energy plus the heat energy generated by the bulb. It did not get mechanical or chemical energy.

Some male birds are very colorful and stand out visually in comparison the their drab counterparts. They also may make loud
vocalizations during courtship. These visual and auditory signals may make then more likely to attract predators and be killed.
Evaluate the statements to find the best description for the evolution of male coloration and vocalization in birds.
-0,)
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
B)
Colorful and vocal male birds may attract the most mates and pass on
their genes. This is an adaptive trait.
Colorful and vocal birds mimic their drab counterparts when predators are
nearby, so predators are just as likely to eat any member of the population.
O
D)
Colorful and vocal birds will only mate with colorful and vocal females,
meaning these groups will become a different species from their drab
counterparts.
Answer:
A)
Colorful and vocal birds may be eaten by predators with greater frequency,
so this is a poor adaptation.
Explanation:
Colourful and vocal male birds may attract the most mates and pass on their genes. Therefore, option (B) is correct.
What is evolution?Evolution is the process of gradual change in the characteristics of a population over time through the mechanisms of natural selection, genetic drift, and gene flow, resulting in the emergence of new species.
While it is true that colourful and vocal birds may be more visible to predators and more likely to be eaten, the fact that they have evolved to develop these traits indicates that the benefits of attracting mates and passing on their genes outweigh the risks of predation. Male birds use their coloration and vocalizations to attract females and demonstrate their genetic fitness, and females select mates based on these traits. Therefore, over time, the male birds with the most attractive traits will be more successful at reproducing, leading to the evolution and persistence of these traits in the population.

A. If 15 ml of a liquid has a mass of 11.85 grams,
(1) What is the density?
(2) What is the liquid?
Answer:
1. 0.79g/mL
2. Ethanol
Explanation:
The density of a substance can be calculated by using the formula;
Density (g/mL) = mass (g) ÷ volume (mL)
According to the information provided in the question, mass = 11.85grams, volume = 15mL.
Hence, density = 11.85g ÷ 15mL
= 0.79
Density of the liquid = 0.79g/mL.
Substances usually have their own unique density, which is one of the properties that distinguish them. In this case, ETHANOL is the liquid that possesses a density of 0.79g/mL.

A population of rabbits lives in a grassy field that is lush and green in summer and covered in snow in winter. At the start of the summer, 75% of the population are white rabbits, and the remaining 25% of the population are brown rabbits. In rabbits, white (W) is dominant over brown (w). During the summer, the field where they live experiences a drought. The summer drought lasts for two years, through many generations of rabbits.
Which prediction BEST estimates the expected percent of white and brown rabbits in the population at the end of the drought?
Answer:
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
Explanation:
hope this helps!
The rabbit population will consist of 35% white rabbits and 65% brown rabbits.
What are the limiting factors of the rabbit population?Until a limiting factor, such as low reproduction, food scarcity, predation, disease, and/or weather conditions restrict populations, the population tends to grow.
Some density-dependent limiting factors are the spread of pathogens, competition for nesting locations, the destruction of habitat, increase in the population of predators. Several predators, including raptors and coyotes, use rabbits as food, but in urban and suburban areas, cats and dogs pose the biggest threat. Some abiotic limiting factors are drought, flood, earthquake, and all types of natural disasters.
Thus, the rabbit population will consist of 35% white rabbits and 65% brown rabbits.

Which of the following correctly explains the differences between artificial and natural selection?
Not sure what the options are, but artificial selection would be when farmers/breeders choose only to plant/breed the organism with desired characteristics in order to cause the evolution of the trait while natural selection is when organisms that are better adapted to their environment usually survive and produce offspring, causing the evolution of their traits which help them to survive.

7. Explain how the equations for photosynthesis and cellular respiration compare.
Answer: In Photosynthesis, carbon dioxide and water is yielded to glucose and oxygen. In respiration, glucose and oxygen is yielded to carbon dioxide and water. C6H12O6 (glucose) + O2(oxygen) → CO2(Carbon Dioxide) + H2O(water) + ATP energy. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.

What is the relationship between the levels of CO2 in the atmosphere and the levels of CO2 in the ocean?
Answer:
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

Explanation:
Describe how knowing the column (group) number is a "cheat code" for determining the number and types of bonds that an element can form.
Answer and Explanation:
The columns of the periodic table are able to inform the number and type of connection that the elements can make. This is because the number of each column informs the number of electrons in the valence layer of the elements. The amount of electrons in the valence layer is what determines the amount and type of bond that the elements make. The elements in column 1, for example, have 1 electron in the valence layer and therefore will make 1 covalent bond. The elements of columns 15, as another example, have 5 electrons in the valence layer and will need to make 3 ionic or covalent bonds.
To describe how knowing the group number is a cheat code to determine the type of bonds that can be formed, we should first define periodic table
What is periodic tablePeriodic Table is a series of elements in which they are arranged in increasing order of their atomic number from left to right but the table also have groups (column) from up to downwards each group have atoms with same number of electrons in their last shell due to which they all have almost similar properties such as same magnetic properties ,same number of bonds formation, metallic character .
We can say that similarity in properties of members of same group is due to same number of valance electrons . For example group 14 i.e. Carbon Family ,all elements of this group will have 4 valance electrons and will form 4 bonds by sharing of their electrons.
