Answer:
Many factors have been shown to affect reaction times, including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual. Sensory neurons convert a stimulus into an electro-chemical signal, which flows the length of the
sensory neuron(s), then through a neuron or neurons of the central nervous system, and then
through the length of the motor neuron(s). Generally, motor neurons will cause a muscle to
contract or a gland to secrete a substance. Reactions that involve only the receptor, the spinal
cord, and the effector, are faster than those which involve processing in the brain. Reactions
which only travel to, through, and from the spinal cord are often called spinal reflexes or cordmediated reflexes; withdrawing one’s hand from a hot stove is an example of such a reflex.
In ‘simple reaction time’ experiments, there is only one stimulus and one response. Catching a
dropped stick, or hitting a button when a light changes are examples.
In ‘recognition reaction time’ experiments, there are symbols to respond to and symbols to be
ignored. There is still only one correct stimulus and one response. An example would be
catching a dropped stick with a word cue, while having to ignore other spoken words which are
not cues.
In ‘choice reaction time’ experiments, there are multiple stimuli and multiple responses. The
reaction must correspond to the correct stimulus. Typing a letter which matches a printed letter
prompt is an example of this type of experiment.

Early scientists were confused by the Euglena because they wanted to classify all living things as either plants or animals. Why do you think the scientists were confused?
Answer:
Euglena perform photosynthesis through the presence of chloroplasts in their cells, but they are also able to feed like animals by consuming and digesting organic material. They have features of both an autotroph(an organisms that produces its own food, such as plants) and a heterotroph (an organism that can not produce its own food and instead need to consume organic matter). Due to having features associated with both plants and animals, this would cause confusion to the scientists at the time who struggled to classify them as either plant or animal.

What are found in both mitochondria and typical prokaryotic cells?
80S ribosomes and circular DNA
70S ribosomes and circular DNA
70S ribosomes only
circular DNA only
Answer:
B) 70S ribosomes and circular DNA
Explanation:
Remember: Mitochondria is found in the cytoplasm of almost all eukaryotic cells.
All prokaryotes have 70S ribosomes. Eukaryotes have 80S ribosomes, with some exceptions like mitochondria and chloroplast.
Circular DNA is DNA that forms a closed loop and carries genetic material. In both prokaryotes and eukaryotes, the chromosome represents circular DNA, although in eukaryotes, the chromosomes are more complex in structure.

Which effect could a mutation in mRNA have on the production of proteins?
mRNA is the messenger molecule, which transcripts the information present in the DNA and then translates it to make the polypeptides. The mutations on mRNA can affect the synthesis of proteins.
The effect of mutation on mRNA:
Point mutations refer to the insertion or deletion of a single nucleotide from the sequence. The mutations can seriously affect the organism and the functioning of the protein formation. The point mutation leads to alteration of the amino acid sequence, which may lead to dangerous diseases or malfunctioning.
Thus, the mutations in the mRNA can result in serious alteration of the amino acid sequence of an organism.

which of the following question must be asked about the use of resources in an economic system
Answer:
what is the most effective allocation
Explanation:
Thirty corn seedlings of equal size were randomly assigned to one of three treatment groups. At the beginning of the experiment, the plants in group I were dried and the mass was determined.
Answer:
The definition of the particular situation is outlined throughout the following section of the justification.
Explanation:
The query given seems to be incomplete. Please find the full issue attachment.
(a)
CO2 provides an inorganic component containing cellular mass. Throughout the atmosphere, plant species suck up CO2. Plants manufacture sugars throughout the mechanism of photosynthesis. Sugar is turned into glucose, cellulose as well as certain carbohydrates processed in cell walls. This raises the density of the plant. The process needs water, Carbon dioxide respectively.(b)
Sunlight is absorbed by chlorophyll as well as converted through chemical energy. The plant utilizes biochemical resources to synthesize sugars. The volume including its plant has risen due to the manufacture of sugars, respectively. For producing sugars, plants require light. The loss in mass has been caused by cellular respiration. There's this community of crops in the dark. They don't do photosynthesis, hence.Because to get power for something like the operations including its plant, individuals had to undergo respiration. So there is no photosynthesis, and therefore there is no sugar development. But instead to release energy, the sugar contained in the plant is eaten. And that's why the amount including its plants holding in darkness reduces.There are 3 steps given below for cellular respiration:
GlycolysisKreb's Cycle Electron Chain of TransportCellar respiration fills certain living things with energy.
⇒ [tex]C_6H_{12}O_6 + 6 O_2\rightarrow 6CO_2 + 6H_2O + (ATP) power.[/tex]
The generated CO2 has so far been delivered from the body including its plant. Therefore the plant mass was indeed decreased by this.
If you are using a microscope with an ocular lens of 10x and an objective lens of 4x, what is the total magnification of the specimen you are viewing.
Answer:
The total magnification is 40x.
Explanation:
In order to calculate the total magnification of a microscope, we have to multiply the magnification of the used lenses. In other words, for this case:
Total Magnification = Ocular lens' magnification * objective lens' magnification
Total Magnification = 10 * 4 = 40Hi please help !!! Thankyou !!

g Catalyzes a substrate level phosphorylation - breaks down sucrose to glucose and fructose - is a type of isomerase - removes one glucose residue from glycogen a. phosphorylase b. sucrase c. phosphohexose isomerase (also called glucose-6-phosphate isomerase) d. pyruvate kinas
Answer:
A phosphorylase removes one glucose residue from glycogen.
Sucrase breaks down sucrose to glucose and fructose.
Phosphohexose isomerase is a type of isomerase.
Pyruvate kinase catalyzes substrate-level phosphorylation.
Explanation:
A phosphorylase removes one glucose residue from glycogen.
The breakdown of glycogen requires a glycogen phosphorylase. It removes a glucose residue from glycogen in the form of glucose-1-phosphate.
Sucrase breaks down sucrose to glucose and fructose.
To metabolize a sugar different from glucose, an organism first has to transform it into glucose so it can then enter the glycolysis. Sucrose is a disaccharide formed by glucose and fructose bonded by an α-1,2 bond. Sucrase breaks down sucrose to glucose and fructose.
Phosphohexose isomerase is a type of isomerase.
It transforms glucose-6-phosphate into fructose-6-phosphate. This is the second step in glycolysis or the Embden-Meyerhof-Parnas pathway.
Pyruvate kinase catalyzes substrate-level phosphorylation.
It transforms phosphoenolpyruvate to pyruvate, releasing in the process an ATP molecule. This is the final step in the Embden-Meyerhof-Parnas pathway.

HOMER NOTICES HIS SHOWER IS COVERED IN GREEN SLIME. hI8S FRIEND BARNEY TELLS HIM COCONUT JUICE WILL GET RID OF THE SLIME. HOMER DECIDES TO SPRAY IT WITH HALF COCONUT JUICE. HE SPRAYS THE OTHER HALF WITH WATER AFTER 3 DAYS OF THE TREATMENT THERE IS NO CHANGE IN THE APPEARANCE OF THE GREEN SLIME OR EITHER SIDE OF THE SHOWER.WHAT IS THE INDEPENDENT VARIAB LE
DEPENDENT VARIABLE
CONTROL GROUP
CONSTANT
Answer:
INDEPENDENT VARIABLE: COCONUT JUICE
DEPENDENT VARIABLE: APPEARANCE OF GREEN SLIME
CONTROL GROUP: THE SIDE OF THE SHOWER HE SPRAYED WITH WATER
CONSTANT: SAME TIME OF MEASUREMENT, SAME SHOWER
Explanation:
- Independent variable is the variable that is changed or manipulated by an experimenter. In this experiment, Homer sprays a side of his shower with COCONUT JUICE and the other side with water. This means that the independent variable is the COCONUT JUICE.
- Dependent variable is the variable that responds to the independent variable. It is the variable that is measured by the experimenter. In this experiment, the dependent variable is the APPEARANCE OF GREEN SLIME on the shower.
- Control group is the group in an experiment that does not receive the experimental treatment (coconut juice). This means that the control group of this experiment is the SIDE OF THE SHOWER HE SPRAYED WITH WATER.
- Constants or controlled variable are the variables in an experiment that are kept unchanged throughout the experiment. In this case, the constant is SAME TIME OF MEASUREMENT, SAME SHOWER.
1. distinguish between different types of mutations 2. explain why mutations may or may not affect phenotype 3. identify internal and external factors that regulate cell division 4.explain cancer in terms of the cell cycle
Answer:
1.)The types of mutations include: Missense mutation: This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene. Nonsense mutation: A nonsense mutation is also a change in one DNA base pair
.2.) Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
3.)External factors include physical and chemical signals. Growth factors are proteins that stimulate cell division. – Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells. Two of the most important internal factors are kinases and cyclins.
4.) In normal cells, the cell cycle is controlled by a complex series of signaling pathways by which a cell grows, replicates its DNA and divides. ... In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation.
