"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%
Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. The pH in the intermembrane space is higher than the pH in the mitochondrial matrix. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. Hydrogen ions are actively transported out of the mitochondrial matrix. Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix. Energy is generated as a result of the difference in hydrogen ion concentration between the mitochondrial matrix and the cytoplasm.

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.
What are the technological building blocks required to fulfill the future plans of the industrial biotechnology? Also state the number of key horizontal issues that need to be addressed when these future plans are implemented?
Answer:
The technological components are: research, natural resources and specialized labor.
These components will be used in issues such as the demand for food, the optimization of natural resources and the control of climate change.
Explanation:
One thing we can say about our future: We will be very dependent on the work of industrial technology. This is because it will be able to use microorganisms, natural resources and biological molecules to develop products capable of meeting some of our needs.
However, with the advance of climatic changes, the demand for food increasingly and the destruction of natural resources in a constant way, we can say that biotechnology will face several challenges and to overcome them need to have technological components such as the establishment of research through of a qualified and specialized workforce that promotes the optimization of natural resources and their products.

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
The famous experiment of Ivan Pavlov where he researched dogs and their responses to stimuli was designed to evaluate this type of learning.
Question 23 options:
Insight
Imprinting
Classical conditioning
Trial-and-error
Answer:
Classical conditioning
Explanation:
Classical conditioning or Pavlovian conditioning is conducted on living organisms to make them associate one or more actions to a given (often familiar) stimulus or stimuli. Ivan Pavlov, in his experiment, trained a dog to associate an action, salivating for food, with the sound of a metronome.
Answer:
Classical conditioning
Explanation:
Ivan Pavlov researched classical conditioning and played a sound for dogs before feeding. The dogs became conditioned to receiving food after the bell. Once the dogs were trained, whenever they heard the bell, they began drooling in expectation of food.
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.
wild animals like tiger,wolf,lion and leopard don't eat plants.does this mean that they can survive without plants?Can you provide a suitable explaintion
Answer:
Explanation:
No, they cannot survive without plants because carnivore eats the animals which is normally a herbivore and the herbivores eat plant.The animals which lion/wolf/tiger etc eats are mostly herbivores so herbivores would die if plants are not available and lion would not get food .
Lion like all other animals requires Oxygen for survival .The present stock of Oxygen would not lost long in absence of plants.Therefore plants are a must for survival of even the carnivores.
hope it helps

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.

Explain, using at least three reasons why the following scenario is a problem for farming.
Situation: A news report stated that many species are facing extinction. The major animals that pollinate our crops are
diminishing, which is causing the farmers to use more artificial means to fertilize the plants.
Answer:
1. Less species pollinating affects the rate of reproduction of plants which eventually leads to their extinction
2. If major species become extinct it could negatively affect the food chain. For example if a predator species dies, it could lead to infestation of mice or an insect that destroys crops
3. Switching to more artificial methods means that farming become less profitable as more money is spent on growing plants so less people farm increasing food prices across the globe

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

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.
