Answer:
arrive at a conclusion
Explanation:
The analysis of data gathered during a particular experiment is necessary in order to arrive at a conclusion that will address the aim of the experiment.
Without data analysis, valid conclusions about the experiment cannot be made and what the experimenter would have is just raw data that cannot say or answer anything about the experiment.
The data collected from experiments can be analyzed in two ways:
Descriptive data analysis Inferential data analysisIn descriptive data analysis, the collected data is summarized, arranged, or described in such a way that a pattern can be seen at a glance. It includes tables, charts, histograms, etc.
In inferential data analysis, the collected data is treated in such a way that an inference can be arrived at based on the study. This includes testing for a significant difference between means, testing for the goodness of fits, correlations, etc.
Which of the following statements about the action potentials in contractile myocardial cells (cardiac muscle) is INCORRECT? Compared to skeletal muscle cells, contractile myocardial cells have a lower (more negative) resting membrane potential. Action potentials are propagated between adjacent cardiomyocytes through gap junctions. The duration of an action potential in a contractile myocardial cell is greater than the duration of an action potential in a typical neuron. During the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium.
Answer: During the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium.
Explanation:
Apart from the fact that contractile cells conduct impulses, it also helps in contractions which are needed for pumping of blood. It should also be noted that the myocardial conducting cells serves as the heart's conduction system. They also have a lower resting membrane potential.
Of the options given, the answer is the last option i.e. during the repolarization phase of a contractile myocardial action potential, the cell is highly permeable to sodium, potassium and calcium. This is wrong.
Repolarization occurs due to a rise in the permeability of potassium and during repolarization, the calcium channels close.

Which letter is on the steepest slope?
(A.) A
(B.) B
(C.) C
Answer:
Letter B is on the steepest slope.
Explanation:
A is not correct because letter A is on a position where the contour lines are not close to each other, suggesting that the slope is not mild.
B is correct because the spacing between the contour lines where the letter B is marked is very small, suggesting that the slope is very steep.
wC is not correct because just like with letter A, the contour lines are not close to each other, but are further away, suggesting that the slope is not steep but it is mild.

Explanation:
Li-Fraumeni syndrome (LFS1) is a rare hereditary disorder that leads to a predisposition to cancer. This hereditary disorder is linked to mutations in the tumor suppressor gene encoding the transcription factor p53. p53 acts at the G1 checkpoint. If damaged DNA is detected, p53 halts the cell cycle. As p53 levels rise, the production of p21 is triggered. p21 enforces the halt in the cell cycle. A variant of Li-Fraumeni, called LFS2, is thought to occur due to a mutation of the CHK2 gene, which is also a tumor suppressor gene. CHK2 regulates the action of p53. Which of the following cascades is most likely to occur in a normal cell that does not contain the LFS mutation?
Answer:
CHK2, p53, p21, cell cycle progression.
Explanation:
In a normal cell with no LFS mutation, during the G1 stage of cell cycle progression, the CHK2 activates if there is damage in the DNA. CHK2 activates p53, which is a tumor suppressor protein that will hold the cell cycle in G1/S until the DNA is repaired. The p53 protein activates p21, a protein that binds to CDK2 and stops the cell cycle. The cell cycle will continue once the damage is repaired.

I have a test about metabolism can someone please explain the subject well? Like just give me a explanation of how it works, and some examples or something.
Answer:
Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.There are three basic metabolism types: ectomorph, mesomorph, and endomorph – definitely words you probably don't use in your normal, day-to-day conversations.If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.
How much do you need to drink?
About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for wome

which theory states that homo sapiens began in a single geographical area and spread out from there?
a. out of africa theory
b. tectonic theory
c. multi-regional theory
Answer:
The out of Africa theory states that Homo sapiens began in a single geographical area and spread out from there.
Explanation:
A is correct because the ''out of Africa theory'' suggests that the Homo sapiens began as a species in Africa and from there it gradually spread out on the other continents across the world.
B is not correct because the ''tectonic theory'' is a theory that has nothing to do with the Homo sapiens species, but it is a theory about the movement of tectonic plates.
C is not correct because the multi-regional theory suggests that the Homo sapiens evolved into multiple regions simultaneously, not in one region only.

The peptidoglycan cell wall and the one or two membranes present also impart a three-dimensional shape to the bacterial cell. The overall shape and arrangement of bacteria are genetically determined, so that each genus of bacteria has a characteristic shape (round, rod, spiral, etc.) and arrangements of the growing cell population (individual cells, chains of cells, or clustered cells).Bin 1 - Image of a single round bacterium.Bin 2 - Image of a single rod-shaped bacterium.Bin 3 - Image of a cluster of round bacteria.Bin 4 - Image of a string of rod-shaped bacteria.Bin 5 - Image of a comma-shaped bacterium.Bin 6 - Image of a corkscrew-shaped bacterium.Drag the descriptive terms to the pictured bacterial shapes.
Answer:
The following images of different types of bacteria are attached here-
1- Single round bacterium- Cocci
2- Single rod-shaped bacterium- Bacilli
3- Cluster of round bacteria - Staphylococci
4- String of rod-shaped bacteria- Streptobacillus
5- Comma-shaped bacterium- Vibrio
6- Corkscrew-shaped bacterium- Spirillium
Explanation:
1- Single round bacterium- Cocci -Any bacterium or archaeon that has a circular, ovoid, or usually round shape is a coccus (plural cocci). Cocci may develop in pairs, chains, or clusters during cell division, depending on their orientation and attachment. Many cocci bacteria do not have flagella and are non-motile, in contrast to many bacilli-shaped bacteria.
2- Single rod-shaped bacterium- Bacilli -A rod-shape bacterium or archaeon is a bacillus (plural bacilli), or bacilliform bacterium. In several different taxonomic classes, bacilli are found. Bacilli typically divide and are solitary in the same plane, but can combine to form diplobacilli, streptobacilli, and palisades.[2]
Diplobacilli: Two bacilli with each other arranged side by side.
Streptobacilli: Arranged bacilli in chains.
Coccobacillus: Coccus-like and oval (circular-shaped bacterium).
3- Cluster of round bacteria - Staphylococci - In the family Staphylococcaceae from the order Bacillales, Staphylococcus is a genus of Gram-positive bacteria. They appear spherical (cocci) under the microscope, and form into grape-like clusters. The species Staphylococcus are facultative anaerobic organisms (both aerobically and anaerobically capable of growth)
4- String of rod-shaped bacteria- Streptobacillus -Streptobacillus is a genus of fastidious gram-negative microaerophilic bacteria, an uncommon disease that develops in culture as rods in chains.t and can be caused by two forms of bacteria, Spirillum minus and Streptobacillus moniliformis.
5- Comma-shaped bacterium- Vibrio -Vibrio is a genus of Gram-negative bacteria with a curved-rod (comma) shape, which can cause foodborne infection in several animals, typically associated with consuming undercooked seafood. Vibrio species, usually found in salt water, are optional anaerobes that test positive for oxidase and do not form spores.
6- Corkscrew-shaped bacterium- Spirillium -Spirillum, a genus of spiral-shaped bacteria of the Spirillaceae family, aquatic with the exception of one species (S. minus) causing a form of human rat-bite fever. For any of the corkscrew-like animals, the name spirillum is used commonly.
Microbiologically, Spirillum is characterized as a gram-negative, motile helical cell with whiplike flagella tufts at each end.
