Describe how new hair fibers are formed
Answer:
Taking nutrients from the dermal papilla, the hair bulb generates new hair cells. As these cells move up through the hair root, they mature through a process called keratinization, fill with fibrous protein and lose their nucleus.

Which explanation best identifies the relationship between mitosis and
reproduction? *
Mitosis is a form of sexual reproduction because the daughter cells form from one
single parent cell.
Mitosis is a form of sexual reproduction because the daughter cells are genetically
different from the parent cell.
Mitosis is a form of asexual reproduction because the daughter cells form a new
nuclear membrane after reproduction.
Mitosis is a form of asexual reproduction because the daughter cells are genetically
identical to the parent cell.
How does the oyster population
In the Chesapeake Bay ecosystem affect the floating to sea floor ratio of algae
populations
Answer:
Analysis of the data shows that the ratio of floating algae to sea floor algae dramatically increased at the same time that oysters were removed from the Bay. ... (It is also possible to infer from the graph that high floating algae levels led to the decline in oysters.

Why do you think it's important for scientists to study plate tectonics? Explain.
Studying plate tectonics is important because it helps explain Earth's surface features, predict natural disasters, investigate Earth's history, explore natural resources, and understand global climate patterns. It is a multidisciplinary field that provides valuable insights into the dynamic nature of our planet.
Scientists study plate tectonics for several important reasons. Firstly, understanding plate tectonics helps scientists explain the formation of different features on Earth's surface, such as mountains, valleys, and ocean basins. By studying the movement and interactions of Earth's tectonic plates, scientists can better understand the processes that shape our planet.
Secondly, studying plate tectonics is crucial for predicting and understanding natural disasters. Earthquakes, volcanic eruptions, and tsunamis are all related to tectonic activity. By analyzing plate boundaries and identifying areas prone to seismic activity, scientists can provide early warnings and help communities prepare for potential disasters.
Furthermore, studying plate tectonics is essential for investigating Earth's history. The movement of tectonic plates over millions of years has shaped the continents and influenced the evolution of life on our planet. By examining the distribution of fossils and rock formations, scientists can reconstruct past tectonic events and gain insights into Earth's geological history.
Additionally, understanding plate tectonics is crucial for exploring natural resources. Many valuable minerals and energy resources are formed as a result of tectonic processes. By studying plate boundaries and their associated geological features, scientists can identify potential locations for mining and resource extraction.
Lastly, studying plate tectonics contributes to our understanding of global climate patterns. The movement of tectonic plates affects ocean currents, weather patterns, and the distribution of landmasses. By analyzing these interactions, scientists can better predict and understand climate change.

A cell is placed in a hypertonic solution. Which will most likely occur as homeostasis is maintained in the cell?
A.
The cell will gain ATP molecules.
B.
The cell will gain water.
C.
The cell will lose water.
D.
The cell will lose sodium ions.
Answer:
B the cell will lose water
Explanation:
Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.
When a cell is placed in a hypertonic solution, it will most likely lose water (Option C) as homeostasis is maintained in the cell.
What is homeostasis?Homeostasis is the ability of an organism or a system to maintain a relatively stable internal environment, despite changes in external conditions. It is a key aspect of biology that helps living organisms survive in their environment. Homeostasis is maintained through a series of physiological processes that regulate different aspects of an organism's biology, such as temperature, fluid balance, and pH
A hypertonic solution is one that has a higher concentration of solutes (e.g. salts) outside the cell compared to inside the cell. This creates an osmotic pressure gradient, which draws water out of the cell and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell will shrink and lose water.

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.

The golden-cheeked warbler and the black-throated green warbler look nearly identical to each other. What type of information could be used to determine if the birds are separate species? Select all that apply. The birds breed with each other where their territories overlap. The birds breed with each other where their territories overlap. The birds show differences in mating songs and behaviors. The birds show differences in mating songs and behaviors. The birds do not breed with each other where their territories overlap. The birds do not breed with each other where their territories overlap. The birds compete for food and nesting sites. The birds compete for food and nesting sites.
Answer:
The birds do not breed with each other where their territories overlap.
Explanation:
The correct answer would be that the birds do not breed with each other where their territories overlap.
A species consists of organisms that are phenotypically similar and are capable of mating to produce fertile progeny.
Hence, the first thing to establish that two organisms are not of the same species is the inability to breed with each other. If an eventuality occurs and they are able to breed, the resulting progeny would be invalid.
Therefore the fact that the golden-cheeked warbler and the black-throated green warbler do not breed with each other where their territories overlap is enough information to determine that the birds are separate species.
