Bats hunt using echolocation, in which they send and receive high frequency sounds to locate prey. When bats hear the sounds of others,
they typically begin hunting in the same area. As the number of bats hunting in the area increases, individuals become more successful at
locating and capturing prey.
Some populations of bats live in areas with high levels of noise pollution, such as near heavily trafficked bridges. How might the hunting
behavior of bats be affected by such an environment?
A
Bats would be less likely to hunt in groups, so an individual's success in catching prey would decrease.
B.
C.
Bats would be unable to use echolocation, which would prevent them from finding any prey.
Bats would be more likely to hunt in groups, so an individual's success in catching prey would increase.
Bats would be better able to use echolocation, which would improve their ability to find prey.
D.
Answer:
A
Simply the noise from heavy traffic will cause the destructive interference which reduces the echolocation,blocking the echoes and therefore prevent prey location for bats.
Generally this reduces the Bats' population, as some could not rely on the echo to locate the prey, leading to starving and death. Thus each bat needs to rely on the individual echolocation from the prey to survive as new hunting adaptation.Since the echolocations has been blocked
Answer:
Bats would be unable to use echolocation, which would prevent them from finding any prey.

In which kind of solution is the concentration of solutes the same inside and outside of the cell? isotonic hypertonic hypotonic concentrated
Answer:
isotonic solution
Explanation:
An isotonic solution has the same concentration of solutes both inside and outside the cell. For example, a cell with the same concentration of salt inside it as in the surrounding water/fluid would be said to be in an isotonic solution.
The solutions can have various concentrations of the solutes dissolved in them. Isotonic solutions have the same concentration of solutes inside and outside the cell. Thus, option a is correct.
What are isotonic solutions?Isotonic is the type of solution that has a similar concentration of the solutes on both sides of the system like sugar and salt in the blood or body fluid. They are the essential part of the body fluid and for the balance of osmosis and diffusion.
The tonicity of the solution plays an important role in the transport mechanism and in the balance of the fluid concentration in the organism. In a hypertonic solution, the concentration is at higher levels and in hypotonic, they have fewer concentrations.
Therefore, the concentration of solutes is the same in and out of the cell in isotonic conditions.

Explanation:
Key deer are found only on certain islands in the Florida Keys. Populations are typically small enough that genetic drift has caused significant deviation among populations on different islands. For example, the population on No Name Key has allele frequencies of A1 = 0.43 and A2 = 0.57 while the population on Big Pine Key has allele frequencies of A1 =0.21 and A2 = 0.79. Construction of roads has recently increased migration rates between these populations to approximately 0.08 per generation. What will the frequency of A1 be on Big Pine Key after a single generation of migration from No Name Key?
Answer:
The frequency of A1 be on Big Pine Key after a single generation of migration from No Name Keyp is 0.2276
Explanation:
Whenever it occurs migration between two populations, there is genetic flux going on. Genetic flux might be considered as an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flux acts homogenizing the allelic frequencies between the two populations, and it might introduce variability.
By knowing the allelic frequencies in both populations at a certain time and the migration rate, we can calculate the allelic frequencies of populations in the next generation. This is:
pA₂=pA₁(1-m)+pB₁ m
pB₂=pB₁(1-m)+pA₁ m
Being
A one population and B the other population pA₁ and pB₁ the frequencies of the p allele before migration, pA₂and pB₂ the frequencies of the p allele after migration, m the migration rateIn the exposed example, we know that:
No Name Key population allelic frequency: A1 = 0.43 and A2 = 0.57Big Pine Key population allelic frequency: A1 =0.21 and A2 = 0.79Migration rate m=0.08Let´s say that p represents A1 allele, and q represents A2 allele.
The frequency of A1 allele (p) be on Big Pine Key (Population B) after a single generation of migration from No Name Key (Population A)
pB₂=pB₁(1-m)+pA₁ m
pB₂=0.21 x (1 - 0.08) + 0.43 x 0.08
pB₂= 0.2276
The allelic frequency in a population after one generation is the allelic frequency of individuals of that population that did not migrate (21 x (1 - 0.08) plus the allelic frequency of the new individuals that came from the other population (0.43 x 0.08).
You can corroborate your result by calculating the q allele frequency in the next generation and summing both of them up. The result should be one.
qB₂= qB₁(1-m)+qA₁ m
qB₂= 0.79 x (1 - 0.08) + 0.57 x 0.08
qB₂= 0.7724
p + q = 1
0.2276 + 0.7724 = 1

Thus, the correct answer is option 4. cerebellum.
Besides the HCT, what other component of blood could be measured to give a better understanding of oxygen-carrying capacity? Explain your answer.
Answer:
The haemoglobin levels or counts can be used.
Explanation:
The oxygen carrying pigment of the blood is the heamoglobin (Hb).it is a protein molecule with for heam groups,Each of the latter can bind with 4 molecules of oxygen in a cooperate bonding.The more oxygen molecules binding by Hb,the more oxygen is carry in RBC.
Therefore if the number of Hb counts is reduced in an individual the volume of oxygen in the RBC of the subject should reduced,Therefore, this should be a good indicator of the lower oxygen capacity of the blood of the individual.
Basically in a physiological female the Hb count/100ml of blood is 12-16g/ml,like wise 13-18g/100mI in a physiological man.
Therefore fluctuations in the levels of these values below the set points is an indicator of distortion in the oxygen carrying capacity of the blood.
The amount of the blood in volume that contains RBC is called Hematocrit. Therefore for accuracy the HCT together with the Hb counts are good indicators of oxygen capacity of the blood.
Hematocrit refers to the volume percentage of the red blood cells in the blood. Oxygen-carrying capacity can be measured by several techniques.
The co-oximetry and Arterial Blood Gas can be used to determine the oxygen-carrying capacity.
The techniques can be explained as:
Co-oximetry is a type of blood test used to measure the oxygen-carrying capacity of the hemoglobin in the blood. The test uses the light of different wavelengths that can pass through the blood to determine oxygen capacity. Arterial blood gas or ABG test is a type of blood test used to measure the pH and oxygen-carrying capacity of the blood present in the artery. It is used to determine the efficiency of the lungs to exchange the gas oxygen and carbon dioxide from the blood.
Thus, the co-oximetry and ABG test can be used to determine oxygen levels in the blood.

What is a substrate? a molecule that acts as a catalyst a place where the reaction occurs a place on the product where the enzyme fits a reactant that is catalyzed by an enzyme
Answer:
a reactant that is catalyzed by an enzyme
Explanation:
Reactants are often referrred to as substrates as those are what enzymes mostly act upon to create products or some desired consequence
Option (d). a reactant that is catalyzed by an enzyme is called the substrate.
SubstrateA substrate exists as a molecule on which an enzyme acts. Enzymes catalyze chemical reactions that concern substrate, where the substrate binds to the enzyme's active site, and an enzyme-substrate complex is created. By action of the enzyme, the substrate exists transformed into a product, released from the active site, and free to obtain another substrate.
Enzyme catalysis exists as the increase in the rate of a process by a biological molecule, an "enzyme". Most enzymes exist in proteins, and most such processes are chemical reactions. Within the enzyme, naturally, catalysis happens at a localized site, called the active site.
The reactant in an enzyme-catalyzed reaction is named a substrate.
Because enzymes can expand reaction rates by enormous factors (up to 1017 times the uncatalyzed rate) and tend to be very precise, typically producing only a single product in quantitative yield, they exist the focus of active research.
Hence, Option (d). a reactant that is catalyzed by an enzyme is called the substrate.

This requires you to use all the things we have learned in this chapter. 1.55 grams of Carbon disulfide
is added to 2.83 grams of Oxygen to form Carbon dioxide and Sulfur dioxide. If the reaction yields
1.1 grams of the Sulfur dioxide what was the percent yield?
27%
14%
Ο Ο Ο Ο Ο
74%
42%
O 63%
Answer: The percent yield is, 42%
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of carbon disulphide}=\frac{1.55g}{76g/mol}=0.020moles[/tex]
[tex]\text{Moles of oxygen}=\frac{2.83g}{32g/mol}=0.088moles[/tex]
The balanced chemical reaction is:
[tex]CS_2+3O_2(g)\rightarrow CO_2+2SO_2[/tex]
According to stoichiometry :
1 moles of [tex]CS_2[/tex] require = 3 moles of [tex]O_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] will require=[tex]\frac{3}{1}\times 0.020=0.060moles[/tex] of [tex]O_2[/tex]
Thus [tex]CS_2[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.
As 1 mole of [tex]CS_2[/tex] give = 2 moles of [tex]SO_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] give =[tex]\frac{2}{1}\times 0.020=0.040moles[/tex] of [tex]SO_2[/tex]
Theoretical mass of [tex]SO_2=moles\times {\text {Molar mass}}=0.040moles\times 64g/mol=2.56g[/tex]
Actual mass of [tex]SO_2[/tex] = 1.1 g
Now we have to calculate the percent yield
[tex]\%\text{ yield}=\frac{\text{Actual yield }}{\text{Theoretical yield}}\times 100=\frac{1.1g}{2.56g}\times 100=42\%[/tex]
Therefore, the percent yield is, 42%

A) Incomplete dominance because the intermediate form of the trait is chosen
B) Co-dominance because the intermediate form of the trait is chosen C) Incomplete dominance because the offspring display alleles for both hair colors
D) Co-dominance because the offspring display alleles for both hair colors
Answer:
A
Explanation
the red haired trait is dominant over the white haired trait. and the results are all red haired offspring. therefore its incomplete dominance
The correct option is D) Co-dominance because the offspring display alleles for both hair colors.
What is Co-dominance?Co-dominance refers to a phenomena, in which both alleles are simultaneously expressed in the heterozygote.
Incomplete dominance is closely related to Co-dominance in which phenotype of the progeny is intermediate of the parent phenotype.
Here, the red haired trait is dominant over the white haired trait and still both alleles are simultaneously expressed in the heterozygote of the offspring with red and white hair traits, thus, the Co-dominance best describes this inheritance pattern.

1. If you had a bunch of wolves and wanted a Chihuahua, how you create one? List just one thing you would do.
2. Explain how your strategy would work.
Hint: Think about what you learned about natural selection.
Answer:
organisms acclimate over time is by adapting to their habitats and their ecosystem. If i were to make a population of wolves into a chihuahua i would make sure that the habitat is smaller and also the amount of resources available should be less than what they are used to. This should cause them to become smaller to help preserve energy.Once they breed and a favorable genetic is present, that wolf is used to breed with another wolf that has a genetic mutation that would make it smaller and more domesticated. By taking genetic mutations that are a result from these changes you can get a wolf to be more domesticated and become smaller. like a chihuahua

The NREM is the first stage of the sleep cycle. It has 3 substages - N1, N2, N3 stages. In the N1 stage individuals feel sleepy, hallucinates. It is the light sleep stage and people can awake from this stage of sleep easily.
N2 stage is the next sleeping stage. In this stage, the electrical waves are more and called theta waves. Here, it is hard to awake. Sleep spindles, K - complex are found in this stage, which helps in a deep sleep.
REM or rapid eye movement is a deep sleep stage. It is also called paradoxical sleep. Here, the brain is more active and the body is paralyzed. During this stage a person dreams.
