Answer:
C. By creating laws or traditions that regulate hunting and fishing
Explanation:
Wildlife resources refer to wild animals (terrestrial, aquatic etc) in their natural habitat. Wildlife is an integral part of our society, however, they are being overexploited by human activities.
According to the options in the question, one way to address the problem of over use of wildlife resources is by creating laws or traditions that regulate hunting and fishing. Laws that compel hunting and fishing, which are the means humans over use wildlife, will help bring the rate at which these resources are used.
For example, creating a law that prohibits hunting in certain areas will help preserve wildlife in that area because it is a punishable offence by the law to hunt. Hence, wildlife resources will be preserved.

Explanation:
how is it that the cells in different body tissues are able to perform different functions the cells exhibit different patterns of gene expression
Answer:
The correct answer is -The cells exhibit different patterns of gene expression.
Explanation:
The genome of a particular cell lies in its DNA sequence the information to show gene expressions which means that they make thousands of various proteins and RNA.
A cell generally expresses only a low ratio of its genes, and the various types of cells in organisms with a multicellular body system arise because various sets of genes are expressed.
Thus, the correct answer is -The cells exhibit different patterns of gene expression.

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.
Select all of the following functions that you think a plant would need to carry out in order to survive. grow take in nutrients from the environment reproduce respond to the environment transport materials through their bodies produce chemicals
Answer:
grow, take-in nutrients from the environment, transport materials through their bodies, produce chemicals.
Explanation:
In order for a plant to survive, it would need to grow and develop, take-in nutrients from the environment, transport materials through its body, as well as produce chemicals within the body.
Growth and development are important for any living organism and without it, an organism is as good as dead. With continuous growth, an organism is able to replace worn-out or damaged cells of the body with new ones.
Plants will also need to take-in nutrients from the environment in order to meet their metabolic requirements. Nutrients are essential for several metabolic processes such as photosynthesis, respiration, excretion, etc.
Materials are also being constantly transported round the body of a plant in order to meet some metabolic processes requirements. For example, manufactured food must be transported from the source of manufacturing to other parts of the body in order to meet nutritional requirements.
Plants also need to constantly produce chemicals within their bodies in order to survive. One of the most important chemicals that plants need to produce is carbohydrate which is necessary for energy generation within the body. Carbohydrate is produced by photosynthesis in plants.

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.
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

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
A chemical engineer wants to design a novel enzyme that is capable of catalyzing a reaction in a hydrocarbon solvent instead of water. Based on the material covered in this course, discuss theobstacles that must be overcome to create such an enzyme. Do you think it would be possible to achieve this goal? Please justify your answer.
Answer:
A few obstacles would make it tough to accomplish this objective. In the first place, the polypeptide backbone is characteristically polar. Hardly any proteins would be dissolvable in a non-polar hydrocarbon. Moreover, to keep up the dissolvability of this protein, most of its amino acids would need to contain hydrophobic or non-polar R groups.
Then again, its charged or polar R groups would need to connect with one another or be covered in the core of the protein away from the hydrocarbon solvent. This would put noteworthy requirements on both the idea of the R groups and the structure of the protein that could take part in substrate recognition or catalysis. By and large, this is certainly not a reasonable objective.

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.

"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%
