How is a ribosome like a house?
The ribosomes in a cell are like the kitchen in a house. It is similar to ribosomes using amino acids to make proteins. The cell membrane in a cell is regulates what can come in and out; it is semipermeable and is made up of phospholipids. A cell’s vacuole can be compared to a refrigerator.
Why are ribosomes like factories?
Ribosomes are one of the smallest organelles in the cell. They make proteins, and are located on the endoplasmic reticulum (ER). These ribosomes are similar to the factory workers, since they both create products, and follow directions from the nucleus/CEO.
What organelle is similar to ribosomes?
The Nucleolus The equivalent to ribosomes in the human body is amino acids. The Golgi body helps to create and package large molecules used in other parts of the cell. This organelle is found in both plant and animal cells.
What can ribosomes be compared to?
The ribosomes in a cell are like the kitchen in a house. It is similar to ribosomes using amino acids to make proteins. The endoplasmic reticulum, or ER, transports things across the cell, and helps make proteins and lipids. The mitochondrion are like the electricity in a house.
What would a nucleolus be in a house?
The nucleolus is located inside the nucleus, it where the DNA is actually contained. of the cell, it is the control center of the cell. It is like the generator of a house where electricity (Energy) for the house (Cell) is generated.
What can cells be compared to?
Cells are Like Cars You can compare the windshield and windows to plasma membranes, since they protect the inside of the car from invaders like insects and dirt.
Why are the cells being compared to a house?
The cell membrane is like the roof on a house because it protect the house from storms and anything else. The cell membrane protects bacteria and other things from coming in the cell. Golgi Apparatus are like the laundry room. The Golgi apparatus sorts and modifies cell products.
What does a cell represents in a real life?
Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.
What is the smallest cell?
Mycoplasma
What does a 95% and 99% level of statistical significance mean?
05,” meaning that the finding has a five percent (. 05) chance of not being true, which is the converse of a 95% chance of being true. To find the significance level, subtract the number shown from one. For example, a value of “. 01” means that there is a 99% (1-.
How do you interpret a 95 confidence interval for relative risk?
Note that the null value of the confidence interval for the relative risk is one. If a 95% CI for the relative risk includes the null value of 1, then there is insufficient evidence to conclude that the groups are statistically significantly different.
How does P-value relate to confidence interval?
The p-value relates to a test against the null hypothesis, usually that the parameter value is zero (no relationship). The wider the confidence interval on a parameter estimate is, the closer one of its extreme points will be to zero, and a p-value of 0.05 means that the 95% confidence interval just touches zero.
What does P 0.05 mean?
P > 0.05 is the probability that the null hypothesis is true. A statistically significant test result (P ≤ 0.05) means that the test hypothesis is false or should be rejected. A P value greater than 0.05 means that no effect was observed.
What does P value tell you?
A p-value is a measure of the probability that an observed difference could have occurred just by random chance. The lower the p-value, the greater the statistical significance of the observed difference. P-value can be used as an alternative to or in addition to pre-selected confidence levels for hypothesis testing.
What is the p value for a 95 confidence interval?
0.05
What is the p value for a 90 confidence interval?
(b) P from CI for a ratio “exp” is the exponential function. The formula for P works only for positive z, so if z is negative we remove the minus sign. For a 90% CI, we replace 1.96 by 1.65; for a 99% CI we use 2.57.
Why is 0.05 the cutoff for the p value?
In the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there’s no difference between the means and conclude that a significant difference does exist. Below 0.05, significant.
