Answer: A
Explanation:
In a population of white (W) and black (w) sheep, 22 out of 244 sheep are black. What is the frequency of the dominant allele in the population?
Answer and Explanation:
To calculate the allele frequency in the population, we divide the number of occurrences of the particular allele by total number of all alleles in the population Allele frequencies can be represented as a decimal, a percentage, or a fraction.
Given the population of white (W) and black (w) sheep, 22 out of 244 sheep are black, the frequency of the dominant allele in the population = 222/244×100=
A scientist compares two samples of white powder. One powder was present at the beginning of an experiment. The other powder was present at the end. She wants to determine whether a chemical reaction has occurred. She finds that neither sample bubbles or dissolves in water. She measures the mass and volume of the solids. Sample one has a volume of 45 cm3 and a mass of 0.5 g. Sample two has a volume of 65 cm3 and a mass of 1.3 g. What should the scientist conclude?
A.
The samples have the same color, so no chemical reaction has occurred.
B.
The two samples do not react with water, so no chemical reaction has occurred.
C.
The densities of the samples are different, so a chemical reaction has occurred.
D.
The densities of the samples are the same, so no chemical reaction has occurred.
E.
The densities of the samples are different, so no chemical reaction has occurred.
Answer:
I think it is C because there densities are different.

What are the potential advantages and disadvantages of a major shift from the hard or traditional path of energy development to the soft or visionary path?
(These were the corresponding textbook pages, if needed) Please read the following from the textbook Environmental Science:
7th Edition - Chapter 17
9th Edition - Chapter 14
Answer:
Advantages of following the soft path, the argument here is alternative sources of power such as hydropower, geothermal energy , wind energy , and photovoltaic cells must be developed. This provides a alternative source to remain in a healthy environment and also function as the society we currently live in using the hard path. Disadvantages of following the hard path result with future generations fearing over the irreversible damage of climate change and the damage done to our atmosphere. The hard path argue that we should continue to operate in the future as we have in the past, except more efficiently. This is close to impossible and will only continue the negative effects the hard path( the path we have been following) results in. The major shift determines the outcome of this world, the futures worries or reliefs and ultimately the survival of humans.

In the biosphere, _________________ is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic acid).
A. Phosphorus
B. Phosphate
C. Photosynthesis
D. Photons
In the biosphere, phosphorus is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid), which is in Option A, as phosphorus is a crucial element in the biosphere as it is a component of both ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid).
What is phosphorus?Phosphorus is essential for the formation of the backbone of the DNA molecule, where it links the sugar and nitrogenous base components of the nucleotides. The phosphate group of each nucleotide forms a covalent bond with the sugar molecule of the adjacent nucleotide, forming a long, stable chain of nucleotides that make up the DNA molecule. The DNA molecule is responsible for transmitting genetic information from parent to offspring and serves as a blueprint for the development and function of living organisms.
Hence, in the biosphere, phosphorus is an important element in ATP (adenosine triphosphate) and DNA (deoxyribonucleic acid), which are in Option A.

Which statement describes how the atmosphere gains energy by convection?(1 point)
Air warmed by the ground rises.
The ground warms the air just above it.
Solar energy warms gases that make up the air.
Energy moves from the clouds to the air.
The statement that describes how the atmosphere gains energy by convection is : Air warmed by ground rises ( A )
The rising warm air from the ground into the atmosphere explains the exchange of heat energy from the ground into the atmosphere through convection and this possible due the variation in density and temperature of the ground air and the atmospheric air.
What is ConvectionConvection is the transfer of heat energy through the movement of a medium such as air or water from one region to another. convection can occur as :

Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.
Explanation:
There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.
