Complete question:
A hypothetical bat species (species 1) lives in a city. Another hypothetical bat species (species 2) established a population in the same city after a number of individuals escaped from a zoo. In isolation, each species prefers to roost in buildings that are three or more stories tall. After species 2 became established in the city, species 1 began roosting only in buildings less than three stories tall, whereas species 2 roosted in buildings three or more stories tall. Observers determined that the bright streetlights at ground level had previously deterred most bats from roosting in shorter buildings. Over many generations of existing in the same city with species 2, species 1 showed changes in eye size and retina structure. Complete the following statements about the two bat species.
Roosting areas in buildings of any height are the _________ of species 1.Roosting areas in buildings of any height are the _________________ of both bat species.____________ between the two bat species occurs because both species prefer the same roosting areas.In parts of the city with only tall buildings (over two stories), __________ of species 1 may occur.Roosting areas in buildings that are one to two stories tall are the __________ of species 1 when species 2 is present.a. fundamental niche
b. realized niche
c. character displacement
d. intraspecific competition
e. interspecific competition
f. (-\-)
g. resource partitioning
h. competitive exclusion
Answer:
Roosting areas in buildings of any height are the fundamental niche of species 1.Roosting areas in buildings of any height are the fundamental niche of both bat species.Interspecific competition between the two bat species occurs because both species prefer the same roosting areas.In parts of the city with only tall buildings (over two stories), competitive exclusion of species 1 may occur.Roosting areas in buildings that are one to two stories tall are the realized niche of species 1 when species 2 is present.Explanation:
The ecological niche is the synthesis of all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The fundamental niche refers only to environmental conditions in which a species can live and survive in the absence of any interaction with other species. The realized niche refers to the restricted conditions in which a species can live and survive as a result of environmental physic characteristics and the interaction with other species.Interspecific competition refers to the interaction between two or more species that use the same fundamental niche. These species compete for the same resources like food, shelter, or water, among many others. Eventually one of the species dominates and the other is displaced. Competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor. Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely -, migrate or get extinguished.A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.
In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.
Which crop leaves soil with the lowest levels of nitrogen?
Answer:
cotton
Explanation:
Cotton crop leaves soil with the lowest levels of nitrogen.
What is a nitrogen?Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
Nitrogen is important to all living things, including us. It plays a key role in plant growth: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants [1]. Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment.

write a letter to the government explaining the dangers posed by global warming/climate change
Answer:
Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner. Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

The hypothalamus regulates the ________.
a. thalamus
b. pineal gland
c. pituitary gland
d. pons
Answer:
c. pituitary gland
Explanation:
The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.
It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.
It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.
Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.
Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.

Color in poison dart frogs is controlled by a single gene with multiple alleles. A blue poison dart frog that is heterozygous for the blue allele (Cb) and red allele (Cr) is crossed to a yellow poison dart frog that is heterozygous for the orange (Co) and yellow (Cy) alleles. Their progeny are 1/2 blue, 1/4 orange, and 1/4 yellow. Determine the order of dominance for the alleles. (Order of dominance is indicated as: A > B > C > D such that A is dominant over all alleles, B is dominant over C and D, C is dominant only to D, and D is recessive to all alleles.)
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.

How are humans impacting biodiversity in ecosystems around the world? Provide two examples to support your claim.
Answer:
as humans population continues to grow, we're cutting down more trees and occupying more lands to suffice the need of citizens, therefore, decreasing the forest biodiversity. Our plastic bags, as well as wastes, are polluting the ocean and eradicating essential species that are required to sustain a balance ecosystem, therefore, decreasing the biodiversity of the ocean that are required to maintain a balance environment.
Human activities have affected in Biodiversity in the ecosystems negatively and such activities include : i) Indiscriminate hunting/fishing ii) Improper waste disposal
Humans in search of food ( meat ) engage in excessive/indiscriminate hunting of endangered species thereby reducing the Biodiversity of animal species present in the wildlife also excessive fishing activities affects the biodiversity of certain species of fishes in our oceans negatively.
When wastes are not properly disposed they degrade the environment and decrease the biodiversity of the ecosystems in the process. the burning of industrial wastes leads to the exposure of certain species to the negative effects of dangerous gases and liquids thereby making the ecosystems to become unbalanced.
Hence we can conclude that some of the human activities impacting biodiversity in ecosystems around the world include : Indiscriminate hunting/fishing and Improper waste disposal

Good job
The chemical symbol for chlorine is Cl. There are seven valence electrons present in chlorine.
What are valence electrons?
Valence electrons are electrons in an atom's outermost shell, or energy level. For example, oxygen contains six valence electrons, two of which are in the 2s subshell and four of which are in the 2p subshell.
The chemical symbol of the element (as found on the periodic table) is written in the Lewis symbol for an atom, and the valence electrons are depicted as dots encircling it.
The number of electrons in an atom's outermost shell is referred to as its valence electrons. The final shell of the chlorine atom now has 7 electrons. As a result, a chlorine atom contains 7 valence electrons.
Therefore, Cl is the chemical symbol for chlorine. In chlorine, there are seven valence electrons.

B. How many needles grow on the giant redwoods in California?
C. What color of carnation flowers do people find most attractive?
D. What is the most number of points ever scored in a professional basketball game?
Answer:
A. What length of time is best to use for the firing of pottery to make it strong?
Explanation:
Point A
What length of time is best to use for the firing of pottery to make it strong?
This is a scientific question for Nancy since while making pots from black mud, it is very important to know how much time is required to fire the pot in order to make it strong. Because if we fire it for too long the pot may be become too hot and will eventually crack. While if we fire for less time it will not become hard enough to withstand its shape. So knowing the proper time to fire the pot is very essential in pottery.
Point B, Point C and Point D are not scientific investigations since it includes ones likes and dislikes, quantities and numbers of goal scored which is not scientific.
Hence, option A is the correct answer.
