How would an increase in nest sites affect a population of pigeons?
The population would decrease.
The population would increase.
The population would remain almost the same.
The population would be reduced the next year.
Answer:
The population would increase.
Explanation:
The increase in be sites will automatically increase the population since there is room for more.
Hope it helps.
An increase in nest sites would likely increase the carrying capacity of the habitat for the pigeon population. Hence option B is correct.
What is Carrying capacity?Carrying capacity refers to the maximum number of individuals of a species that an ecosystem or habitat can support sustainably over a long period of time, taking into account the available resources such as food, water, and space.
It is a concept used in ecology to describe the relationship between population growth and limiting factors, such as resource availability and environmental conditions.
The carrying capacity of habitat is not fixed and can change over time due to changes in the availability of resources or changes in the environment.
For example, a sudden increase in rainfall may increase the availability of water and thus increase the carrying capacity of a desert ecosystem. Similarly, a decrease in the availability of resources such as food or water can reduce the carrying capacity of an ecosystem.
Hence option B is correct.

What occurred during immune system development to result in the presence of antibodies that can bind to the thyroid receptor? g
Answer:
If the immune system has a destructive and autoimmune response, it produces specific antibodies, which bind to the receptors of the thyroid cells and destroy them thinking that they are antigens or factors not characteristic of the body.
Explanation:
This happens because the thyroid cells do not present on its surface the histocompatibility complex, which is a surface protein similar to the proper and non-proper "seal", that is, it is the demarcation by which the antibodies and the cells are guided to recognize what foreign to the organism.
The histocompatibility complex is sometimes absent or rather mutated, thus generating that these cells are considered not their own and that the antibody is a receptor in order to generate the autolysis pathway or even the immune defense pathway.

During Transcription, a(n) ________ is created in the __________.
Answer:
During Transcription, an mRNA is created in the nucleus.
Explanation:
Transcription is the mechanism where the genetic information contained in one strand of the DNA molecule is decoded in the messenger RNA (mRNA) molecule, which will be subsequently used as template to synthesize a protein during translation. In eukaryotes, transcription is a nuclear process that has three phases: initiation, elongation and termination. During initiation, an RNA polymerase enzyme and different transcription factors form the initiation complex that binds to the promoter gene region and thus synthesizes the first RNA nucleotides. Subsequently, this RNA sequence is elongated by the action of the RNA polymerase. Finally, during termination, the terminator sequence in the DNA template induces the release of the DNA and this mRNA sequence is terminated.

According to Sam's soap recipe, she needs 945 grams of coconut oil. To measure out the coconut oil, Sam first places a liquid measuring cup on a kitchen scale and sets the scale to 0 grams. She then pours coconut oil into the cup until the scale reads 945 grams. She notes that the total volume of the 945 grams of coconut oil is 1.05 liters.
The question is incomplete, however, the question is asking about the density of coconut oil by the given data
Answer:
The correct answer is - d = 0.9402
Explanation:
Given:
mass of the coconut oil in cup = 945 gm
the volume of coconut oil in cup = 1.05 liter
solution:
we know that,
volume × density = mass
then, 1.05 × d = 945
d = 945/1005 (converting the liter value to ml)
d = 0.9402 (at room temperature)
The correct answer is - d = 0.9402
the diagram below shows a sarcomere if a disorder makes it impossible for atp to bind to the myosin head what would happen to the sarcomere?
Answer:
B. The myosin and actin would not separate, and the sarcomere would remain contracted
Explanation:
ATP (adenosine triphosphate) acts both in the binding of myosin to actin, which occurs during muscle contraction, and also in its separation, which occurs during muscle relaxation.
When ATP is lacking, myosin remains attached to actin, causing muscle stiffness. This is what happens after death, producing a state of cadaverous rigidity (also called "rigor mortis").
An intense and uninterrupted stimulation causes the muscle to reach the maximum degree of contraction. Then, the muscle remains in contraction, this state is called tetany.
A very prolonged state of tetany causes muscle fatigue, in which, due to ATP deficiency, can cause a loss of muscle contraction capacity, after its relaxation.
"While bird watching, Carl hypothesized he could identify 73 different types of birds in one day. He actually identified 65 different types of birds. What was his percent error
Answer:
15.87%
Explanation:
Carl's percentage error would be 15.87%.
From the data, the hypothesized number of birds Carl could identify is 73.
The actual number of birds he was able to identify is 63.
The margin of error between the two = 73 - 63 = 10.
Hence, percentage error = error/true measurement x 100%
= 10/63 x 100% = 15.87%
A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these Bt plants, only 5% survive unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide. When the farmer first plants Bt cotton, the frequency of the R allele in the cotton bollworm population is 0.01. What will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton [answer]
Answer:
the frequency of the resistant allele after one generation is 0.989
Explanation:
Given that :
A farmer plants Bt cotton that is genetically modified to produce its own insecticide.
Of the cotton bollworms feeding on these Bt plants, only 5% survive
i.e the survival rate s = 5% =0.05
unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide
Frequency of R allele = 0.01
In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.
According to Hardy-Weinberg Equilibrium ;
p+q = 1
Let p = R and q = r
R + r = 1
0.01 + r = 1
r = 1 - 0.01
r = 0.99
Now; the frequency of the resistance allele after one generation can be calculated as :
[tex]q' = \dfrac{q(1-sq)}{1-(sq^2)}[/tex]
where ;
q' = R
q = r
[tex]q' = \dfrac{0.99(1-(0.05 \times 0.99))}{1-(0.05 \times 0.99^2)}[/tex]
[tex]q' = \dfrac{0.99(0.9505)}{1-(0.049005)}[/tex]
[tex]q' = \dfrac{0.940995}{0.950995}[/tex]
q' = 0.989
Thus; the frequency of the resistant allele after one generation is 0.989

At your laboratory you are observing skin cells labeled 'defective' to determine what is wrong with them. After careful observation you notice that the cytoskeleton is there, but the cell is still having trouble maintaining its shape. Infer what could be damaged.
A. Cell wall
B. Capsule
C. Cilia
D. Actin filaments
Answer:
D. Actin Filaments
Explanation:
Actin filaments are part of cytoskeleton and they are the central key player in maintaining cell shape and movement. So my guess is that since cytoskeleton is present, there is something likely wrong with the actin filament.
Even in the presence of the cytoskeleton, the shape is not maintained in the cell due to the damaged actin filaments. Thus, option D is correct.
What are actin filaments?Actin filaments are the part of the cytoskeleton that forms bundles and meshworks to provide the cell shape and structure. They are the central part of the cell shape and motion.
As the cytoskeleton is present then, there is the possibility that the actin filaments of the cells are damaged so that the cell is not able to maintain the cell shape.
Cell wall, capsules, and cilia have no role in the animal cell like the skin cells to maintain the cell shape as animal lacks cell wall in the structure and are not involved in providing cell shape.
Therefore, the actin filament is damaged.

Due to the fact that it is reactive, on the left, everything to the left of the arrow is a reactant, and reactants are on the left side, 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂, hence option C is correct.
What is the equation for photosynthesis?Everything to the right of the arrow is a product of photosynthesis, hence glucose and oxygen are also products of photosynthesis.
Carbon dioxide and water are the reactants, whereas glucose and oxygen are the products.
By using light energy that is caught by chlorophyll (shown by the arrow), the reactants, six carbon dioxide molecules, and six water molecules are transformed into the products, a sugar molecule, and six oxygen molecules.
Therefore, the reactants of photosynthesis are carbon dioxide, water, and solar energy, 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂, hence option C is correct.
