Describe what the observations imply about how starlings are affected by flocking behavior in the wild and explain how evidence suggests that flocking behavior provides an advantage to starlings.
Answer:
Explanation:
Starling is a bird from the family sturnidea. It originated from Europes and Asia from where it introduced to other part of the world. They lives in the wild.
Starling birds moves in group or tight flock from a place the other. They usually form a flock called murmuration where they move together in group following each other to avoid predation.
Starling have been able to survive on the wild with this behaviour. They stir above the average height of their neighbor in a coordinated manner preventing them from being caught by preys.
The bunnies in a forest have different colored fur at different times of the year. The bunnies you see have brown fur in the fall. The bunnies you see in winter have white fur. What is this an example of?
a. Evolution
b. Artificial Selection
c. Natural Selection
d. Selective Breeding
Answer: A) Evolution or B) Natural Selection
Explanation: The fur of these bunnies change color with the seasons in order to better blend into their environment. This is an example of a species evolving to better survive!
However, this could also happen as a result of natural selection. Those who were able to better survive would pass on their genes for fur that changes with the seasons.

Do you think it would be possible to construct a pyramid where the number of carnivores was more than the number of herbivores? Why or why not?
Do you think it would be possible to construct a pyramid where the biomass of carnivores was more than the biomass of herbivores? How does this compare to a numbers pyramid.
Please help!
Answer:
Explanation:
Pyramid is the use of graph to represents the flow of energy in each trophic level. There are five trophic level and each has its own energy level pyramid help to show the energy at each level.
Each energy level must have at least One tenth of the energy level of the organisms before itself, this indicates that the energy in the lower tropic level is higher than the trophic level above.
Hence, carnivores cannot be more than herbivores in a biomass they need enough of herbivores to survive in the biomass as the energy level moves from the herbivores to the carnivores.

Paige turns on an electric space heater in the center of her bedroom. The coils glow, and the room becomes warmer. How is heat reaching the corners of Paige's bedroom?
Think of it this way. Osmosis occurs when water flows to a different side given its a membrane or not. This is because it flows to a less dense area to reach equilibrium between the two sides. Heat is very similar. It will try to spread to places where there is not as much heat. Keeping the laws of heat travels up, the heat from the coils will reach the ends. We call this "Thermal Equilibrium"

Explanation:
Imagine an object launched from Earth as shown in the image. Identify where the object has overcome the gravitational pull of Earth.
Answer:
the object defeats the force of gravity on the arrows on the left where they do not follow the circumference of the earth.
since the force of gravity makes the objects keep rotating near or even on the Earth's surface.
If any object overcomes this force, it will not rotate on the surface of the earth and will not be attracted to the center
Explanation:
this is because the center of the earth works as if it were a magnetic pole that attracts everything close to the earth to its center, if something deviates as in the arrows on the left, it means that the force of attraction towards the center or force of gravity does not act on the objective as it must have a force applied or of its own greater than that written

Is there a connection between intensity of UV radiation and skin color?
Answer:
Explanation:
Sun exposure which also includes its intensity is responsible for detrimental damage to the skin ranging from sunburn, etc and skin cancer.They also aid in the accumulation of DNA lesions which are unable to be repaired by the body systems which are distributed throughout the whole epidermal layers and the uppermost dermal cells in light, intermediate and tanned skin while they were restricted to suprabasal epidermal layers in brown or dark skin in interaction with the individual's genetics.
To solve this problem of damage to the skin, a way to do this was to evolve skin that was dark to protect against the sun's more damaging rays. Melanin, the skin's brown pigment, is a natural sunscreen that protects tropical peoples from the many harmful effects of ultraviolet (UV) rays as the sun rays is a lot high in these areas.
List three particles found in blood plasma and give their main purpose.
Answer:
Blood plasma is a 'yellowish liquid' component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.

Since their variations are best suited for the environment, they have a higher chance of surviving.
Devegetation affected a number of nutrient reservoirs and processes in the experimental watershed. Note that the rate of decomposition was not affected by devegetation because the decomposers were not affected by the treatments and because the plant remains contributed plenty of organic nutrients to the soil to sustain decomposition for the duration of the experiment. Drag the labels to indicate the change in the size of the reservoir or the change in the rate of the process as a result of devegetation. Labels may be used once, more than once, or not at all.
Answer:
Devegetation affect the nutrient reservoir and watershed due to not using of nutrient and increases soil erosion.
Explanation:
Devegetation refers to no vegetation on a piece of land. If there is no vegetation present on land, the nutrient reservoir remain full because no plant is available for the absorption of nutrients from the reservoir. Devegetation also affect water quality of watershed. Erosion is the main problem of those areas where there is no vegetation and the upper layer of soil is washed by the rainfall.

Which feature increases the absorption of glucose in the small intestine
Answer:
The correct answer is villi.
Explanation:
The carbohydrates consumed by human beings are further dissociated into its mono forms, that is, fructose, glucose, and galactose. Of these monosaccharides, about 80% is glucose, which gets absorbed with the assistance of absorptive cells in the small intestine. In the walls of the small intestine, the food after digestion is passed into the blood vessels via the process of diffusion.
The mucosa or the inner wall of the small intestine is enveloped by finger-like tissues known as villi that further comprise microscopic finger-like outcrops called microvilli. These villi and microvilli enhances absorption of nutrients as they increase the surface area of the small intestine. Thus, the absorption of glucose within the small intestine is enhanced by the presence of villi.

Which region would likely have the greatest amount of biodiversity?
OA
B.
a mountainous region with two ecosystems, each of which supports a few different species
a grassland region with one ecosystem, which supports very large populations of a few different species
a coastal region with three ecosystems, each of which supports many different species
a cave region with one ecosystem, which supports small populations of many different species
D.
Answer:
A
Explanation:
A coastal region with three ecosystems, each of which supports many different species likely to have the greatest amount of biodiversity. The correct option is C.
The highest level of biodiversity would probably be found in a coastal area with three different habitats.
Because there are so many different habitats and ecological niches along the coast, there is frequently a high biodiversity there.
Sand beaches, rocky shorelines, coral reefs, mangrove forests, and salt marshes are just a few examples of the diverse environmental conditions that can be found in a coastal region due to the interaction of marine, estuarine, and terrestrial ecosystems.
There is a larger total species variety because various species are supported by each ecosystem and are adapted to their own habitats and environmental variables.
Additionally, because they produce intricate and interconnected ecological networks, interactions between different habitats further improve biodiversity.
Thus, the correct option is C.
