It works because your brain creates images from dots. That’s how you can watch shows that you like a whole lot.
Answer:
The fovea works because your brain creates images from points.
Explanation:
The fovea is located in the center of the eye's retina. It is the structure capable of capturing stitches from what you are viewing and sending those stitches to the brain, which will "stitch" all stitches together and form an image. In summary, the fovea is able to project an image to the brain through pieces of the image, it is formed by cones that allow the transmission of light to the photoreceptors of the eyes.

an advertisement on tv claims children grow faster with the use of vitamin gro. vitamin gro is a 25mg pill taken twice a day. the viewer has little knowledge about how children grow, but he knows that children need a complete diet and a good exercise routine. he decided to put the commercial to the test. the viewer uses his 6 nieces who are the same age to conduct the experiments. to make the experiment easier he uses his six nieces using labels such as child 1, child 2 and so on. he records their height every 3 days for 7 days. What are the variables?
Answer:
Independent variable - vitamin gro and exercise routine.
Dependent variable - growth of children or nieces.
Explanation:
There are two variables present in an experiment called dependent and independent variables.
Independent variables are those variables which can be controlled in an experiment and dependent variables are those variables which are measured in the experiment under the influence of the independent variable.
In the given experiment, the independent variable will be vitamin gro and exercise routine and the dependent variable is the growth of children or nieces because vitamin gro and exercise routine can be controlled and growth of children is dependent on vitamin gro and exercise routine.
Predict what will happen to the following lung volumes and capacities during strenuous exercise. Assume that you are comparing from a baseline of normal resting respiration.
Lung Volume or Capacity Predicted change from resting baseline : Use Increase, Decrease or No Change
TLC (total lung capacity)
No change
VC (Vital capacity)
IC (Inspiratory capacity)
FRC (Functional residual capacity
TV (Tidal volume)
IRV (Inspiratory reserve volume)
ERV (Expiratory reserve volume)
RV (Residual volume)
Answer:
During intense exercise:
lung capacity increases
vital capacity increases
respiratory capacity increases
functional residual capacity increases
tidal volume increases
the inspiratory and expiratory reserve volumes decrease as does the residual volume.
Explanation:
Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.
If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.
Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.
It is important to clarify that all the above processes are accompanied by an increase in the size of the chest cage

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If a researcher moves the repressor gene (lacI), along with its promoter, to a position at some several thousand base pairs away from its normal position, which of the following results would be expected?
A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.
Answer:
D) The lac operon will function normally.
Explanation:
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.
If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.
Promotor:
It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.
Here, researcher moved the repressor gene of lac I , along with its promoter.

fur color in mice is affected by a single gene the gene for fur color has two alleles: b that causes dark brown fur and b that causes light brown fur. What is or could be the genotyes of a mouse with dark brown fur
Answer:
(BB) or (Bb)
Explanation:
Given that (B) allele , is responsible for fur that is dark brown, and (b) allele is responsible for fur color that is light brown, the dominant allele is (B) allele for dark brown fur. Dark brown fur allele would always express itself over the recessive allele, (b).
For a mouse that has dark brown fur, the possible genotype it could have is either (BB) => 2 dominant allele, or (Bb) => 1 dominant allele and a recessive allele. The dominant allele would always express itself even in the presence of the recessive allele.

SUBMIT
Answer:
B. Hypothalamus
Explanation:
The hypothalamus contains the pleasure center of the brain, the nucleus accumbens. The hormone dopamine is released from this part of the brain in response to or anticipation of pleasurable activities such as eating good food, monetary rewards as well as when taking psychoactive drugs.
The release of dopamine affects other feelings such as happiness, focus, being alert as well as staying motivated. it also affect some voluntary actions as well.
Constantly seeking out activities that stimulate dopamine release may lead to addiction to such activities as in drug addiction.

which of the following would differ if you compared the same reaction taking place with and without an enzyme
a. the chemical energy of the reactants
b. the chemical change of the product
c. the energy required to the reaction
Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.

reaction would it be? Hint: What is the reverse of the equation you just
balanced? (1 point)
Answer:
Reversible reaction
Explanation:
If the elements of the product combine together in a chemical reaction, this reaction is called reversible reaction because the reaction moves in backward or reverse direction. For example, if acid i. e. HCl combine with base i. e. NaOH which are the reactants, it produces two products salt (NaCl) and water (H2O). If salt (NaCl) and water (H2O) combine again with each other, it produces acid i. e. HCl and base i. e. NaOH, such type of reaction is called reversible reaction.

And exactly why trees need oxygen for photosynthesis ?
Answer:
Photosynthesis is a chemical process that leads to the release of oxygen as a by-product and is necessary for cellular respiration
Explanation:
The plants produce or make oxygen form the wastes of starch, sunlight carbon dioxide, and water. In order to burn the sugar that is stored in the plants, it needs to have sunlight which requires oxygen. As the break down of sugar C6 H12 O6 to CO2 and H2O needs O2 to do it. Which is called cellular respiration. This is also stated by the first law of thermodynamics that energy cannot be created and neither destroyed but transforms itself. Photosynthesis is the chemical process that is used to convert this chemical energy which makes carbon and water into glucose and oxygen is released as a by-product.Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

In the quest to understand the basis of infertility in humans, researchers have identified a mutation in a gene associated with chiasmata. This protein normally acts to promote homologous recombination.Why might a defect in homologous recombination have consequences for fertility?A. The chiasmata halts the whole process of meiosis, if crossover do not form properly.B. Crossover formation is a necessary step in meiosis I to ensure proper chromosome segregationC. A checkpoint requires a certain level of genetic variability for meiosis to proceed.D. Chiasmata are the connections between the centromeres and the centromeres that pull them to each pole of the daughter cells.
Answer:
B. Crossover formation is a necessary step in meiosis I to ensure proper chromosome segregation
Explanation:
Crossing-over is a unique phenomenon that occurs in the prophase I stage of meiosis I, where non-sister chromatids of homologous chromosomes exchange their chromosomal segment. The physical point where this exchange occurs is called CHIASMATA. Hence, a mutation that affects the gene associated with the chiasmata will affect the occurrence of crossing over or homologous recombination.
Crossing-over, through the formation of the chiasmata, is responsible for the physical alignment and proper segregation of chromosomes into gametes. Naturally, the chiasmata formed as a result of recombination during meiosis helps ensure that the chromosomes stay together until it is the right time to separate. This way, any chromosomal defect in the resulting gamete is prevented.
However, an error or defect in homologous recombination might give rise to gametes with chromosomal disorder, a condition known as ANEUPLOIDY i.e. missing or additional chromosomes in gametes. This can affect the fertility of the involved human.
