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.

(b) Explain how the addition of a phosphate group to certain amino acids of Brec likely affects the tertiary structure and function of Brec. Explain how
the addition of a small RNA could prevent the activation of kinase D?
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
1. Adding the phosphate group to the amino acid chains is known as phosphorylation. This attachment affects the tertiary arrangement and function of Brec.
Amino acids join together to form the protein that needs to be stimulated and deactivated for proper functioning.Protein phosphorylation is very crucial in post-translation modification.For protein function, it acts as an activator, inhibitor, reversibly on and offs the switch.Phosphorylation assures a reversible process to the cell to transmit signals for the cell functioning.Therefore, Brec activity can be controlled by the phosphorylation of proteins.2. Small RNA's are RNA fragments which is around 150 nucleotide in length.
Functionally significant small RNA's such as siRNAs, microRNAs scaRNAs and many other acts as regulatory molecules which target and adheres to the mRNA transcripts.This binding inhibits the translation process or degrades the mRNA by activating the RNA interference (RNAi) pathway.RNAi pathway is used to suppress the activation of the kinase D.To learn more about phosphorylation and small RNA follow the given link below:

Explanation:
Cheetahs have become an endangered species due to hunting and loss of their habitat. As a result, there is now very little variation in the traits within their small populations. Which of the following is a result of the limited variation in traits in today’s cheetah population compared to earlier cheetah populations that had greater variation in traits?
A. Cheetahs in current populations are more resistant to new diseases.
B. Cheetahs in current populations have better chances of survival today than they did in the past.
C. Cheetahs in current populations are less likely to become extinct.
D. Cheetahs in current populations are less likely to be able to adapt to environmental changes.
Answer:
Cheetahs in current populations are less likely to be able to adapt to environmental changes
Explanation:
i got the question wrong cuz some1 but im willing to help others this is the correct answer D is the correct answer:)
Cheetahs in current populations are less likely to be able to adapt to environmental changes. Therefore, option (D) is correct.
What is limited variation?Less possible combinations of characteristics indicates a lower level of genetic diversity within the population. Because of this, there may be fewer genetic variations available to supply potentially beneficial characteristics that can aid in the survival of the population. This can have a detrimental impact on the population's ability to adapt to changes in its environment, which can have negative effects.
Because there is less genetic variation in the current population of cheetahs, it is possible that they will have a reduced ability to adjust to changes in their environment, such as the appearance of new diseases, shifts in climate, or the loss of habitat. This might make the possibility of the population going extinct significantly more likely. Hence, the solution that you should select is option D.

Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?
Complete question:
Now you are ready for your first major assignment. Your colleagues are investigating a newly seized tusk and wonder if the tusk is from a recently discovered crime where 10 elephants from the same population were found dead with their tusks removed. The genotype of the seized tusk for five short tandem repeat (STR) loci is shown in Table 1. Allele names for each of the STR loci correspond to their size in base pairs (bp). Table 2 lists the genotypes of the same five STR loci for 10 recently slaughtered elephants.
Did the seized tusk come from one of the recently slaughtered elephants? ________ What evidence supports your finding?
Note: You will find the tables in the attached files
Answer:
Probably the seized tusk belonged to elephant number eight.
Explanation:
Potentially, the seized tusk might belong to individual number eight. In both the tusk and the elephant, the genetic analysis resulted in the same-sized alleles for each locus.
FH19: 193 193FH60: 147 147FH67:97 103FH71: 62 62FH129: 152 160The fact that, among the ten individuals of the population, only the individual number 8 matches the tusk for SRT loci, suggests that it belongs to the animal, but it does not ensure it 100%.
how does shell color work to protect the egg from sunlight?
Answer:
Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight
Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.
The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell

For each of the following minerals, say what properties of the material make it important in carrying out it's particular function.
a. tar roads
b. iron bulgar bars
c. plastic furniture
d. metal jewellery
e. clay for building
f. cotton clothing
Answer:
1. Tar Roads: The qualities of Tar that makes it ideal for road construction are:
The tar-like material that is used for road construction is a combination (emulsion) of water and liquid asphalt. It serves the purpose of permeating and closing up small lacerations in the existing pavement.
When the emulsion sticks to the "gravel" it reduces the potential for vehicles to skid on the road thus enhancing safety. The "gravel-like" emulsion is applied by rolling and sweeping.
Qualities of Tar are:
Adhesive: its the ability to stick to surfaces including materials such as gravel which it holds together makes it great for road construction;Waterproof: It is not water-soluble. Hence is not easily susceptible to the effects of running water. Resistant to High Temperature: The melting point of Tar is 54 degrees centigrade. The ground can heat up to 45 degrees celsius thus making Tar perfect for road construction as it can remain rigid even in the worst temperatures.2. Iron Burglar Bars
Steel bars are made from iron. The qualities of steel which make it perfect for securing places and things are:
Strength; This is the ability to withstand breakage and or destruction. Toughness: Steel is very tough and can not easily bend or break under static loads. Weldability: Most steel bars are actually welded together. Without this ability, steel probably would be useless as a material that can be used for protectionDurability: The only factor that degrades steel is rust. Rust happens when steel is exposed to oxygen which can be found in air and water.3.) Plastic Furniture
The primary qualities of plastic that make them suitable for furniture are:
Chemical stability: It does not rust or degrade when exposed to weather elements such as oxygen, water, etc. Good impact resistance: Depending on its thickness, plastic can bear a lot of weight and can take a lot of impact without deforming or breaking Good transparency and wear resistance: Plastic can be made transparent. This quality is essential for aesthetic purposes and hence can be used for various kinds of good-looking furniture. As furniture, its surface does not come off like hence it's durability.Low thermal conductivity: This means that it can bear heat without transmitting it easily. Ability to General formability, good coloring, low processing cost.4) Metal Jewellery
One of the best metals for jewelery is Tungsten. This is so because it is more durable and stronger than any other kind of material that can be used for jewelery purposes. It is about ten times harder than 18K gold and about four times harder than titanium. Other materials that can be used are:
titaniumstainless steel and cobalt5) Clay
In it's raw form, clay used for building might not be the best idea as it susceptible to water absorption and hence deformation which generally leads to a collapse of the structure. However, it becomes an excellent material of choice after it has been hardened into brick.
Brick is preferred in construction due to the following qualities:
hardnessHigh Compressive strength, Low Water AbsorptionFrost resistanceFireproofGreat Insulation6) Cotton is usually preferred as the material of choice for most kinds of clothing due to the following qualities:
Softness. The cotton plant is soft and fluffy and results in a fabric often retains that soft feel. Durability: Its molecular structure makes it able to last very long. Absorbency: it is able to absorb moisture/water. Hence making it more comfortable than synthetic materials High Dye Tolerance: Ability to hold dye well is an indespensable quality of a good fabric. You don't want to have a fabric whose colours are quick to fade. Breathability: This reduces is very important especially during summer or when the weather or environment is very hot.Cheers
The tar is roads that have quantities to make them deal with the construction. The liquid is a mix of asphalt and can be adhesive and waterproof.
The iron bars are used for securing the place and things. plastic furniture is used to make suitable furniture and is used for chemical stability etc. The metal jeweler is of titanium, cobalt and stainless steelLearn more about the following minerals.
