MASTERY CONNECT MITOSIS
Answer:
In the diagram showing cell division by mitosis of a cell (W), the statement that is correct with respect to cells Y and Z is that these cells are identical to each other and to cell W (last choice).
Explanation:
Mitosis is the cell division that occurs in somatic cells, important for the processes of growth and development of living beings, in addition to tissue renewal and repair.
The result of the mitosis process is to obtain two daughter cells identical to each other, from an original cell. This implies that their morphology and genetic charge, diploid, will be the same.
The diagram shows a diploid cell (W) with a complete set of chromosomes, which are duplicated during the division process (X) and then distributed equally between the two daughter cells (Y and Z).
The other options are not correct because, as explained above, in mitosis the daughter cells are identical to each other and to the original cell.

Answer:
Ос. He used DNA testing to compare evidence to possible criminals.
Explanation:
Detective Scott worked to solve cases by the use of DNA testing which is an efficient way to solve a criminal case because DNA testing provides all information about the criminal. Due to this DNA testing, he solved many cases and the criminal caught with the help of this testing. If he can't use this DNA testing method then the case would not be solved.

A scientist wanted to see if the number of eggs in a nest varied according to latitude. She decided to study a specific species of bird found in both tropical and temperate zone areas. One hundred nests were examined,in each of the 3 temperate zone areas (300 nests)and 3 tropical zones areas( 300 nests) for a total of 600 nests. In each case,the number of eggs were counted. In this investigation, what is the:____.
A. Question bejng asked?
B. Independent variable?
C. Dependent variable?
D. Constant?
E. Hypothesis?
F. Sample size?
G. Repeated measure?
Answer:
A. Does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?
B. The latitude of the area
C. The number of eggs
D. The species of the bird
E. The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.
F. 600 nests
G. The number of eggs
Explanation:
A. In the investigation, the scientist wanted to see if the number of eggs in a nest varied according to latitude, therefore, the question she will be seeking an answer to is: does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?
B. The independent variable is the variable that is not affected by the other variables being measured in an investigation. In the investigation by the scientist, the latitude of an area is the independent variable in that it is independent of changes in the other variable- the number o eggs- in the investigation.
c. The dependent variable is the variable that is affected by changes to the other variable in an investigation. The number of eggs is expected to vary according to latitude, is therefore, it is the dependent variable.
D. The constant is the factor that does not change during the experiment. The bird species is the constant as it does not change in the investigation.
E. A hypothesis is a specific statement predicting the result of an investigation or study.
In this study, the hypothesis could be: The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.
F. The sample size gives the the total number of subjects, individuals or observations in a study. In this case, the subjects are bird nests, and the sample size is 600 nests.
G. The number of eggs in all the nests were counted; therefore, it is the repeated measure.
If all Insectivorous birds and remaining beetles were removed from habitat 2 and SOO additional dark brown beetles and 500 additional light tan beetles were then released into habitat 2. What would best estimate of the number of additional dark-brown beetles that would be expected to be recaptured In habitat 2 after one more week?
Answer and Explanation:
Throughout the world, the most different species of organisms are insects. As compared to the other species, the number of insect species is greater. The exact number of insect species can be estimated from previous and current studies. Approximately nine hundred thousand species of insects are known. Insectivorous birds are those birds that feed on insects. For numerous growing insectivorous birds, insects are used as a source of protein. One of the most common kinds of insects is beetles. They are found everywhere. Beetles eat fruits, leaves, and other parts of the plant. The reproductive and fertility ability of insects is remarkable. In habitat 2, beetles and insectivorous birds were living. If all insectivorous birds and remaining beetles were removed from habitat, two and five hundred additional light tan beetles and 500 dark brown beetles were released in habitat 2. After one more week, one thousand dark brown beetles would be expected to be recaptured in the habitat 2.

Explanation:
The GO is a stage outside of the cell cycle commonly referred to as the "resting stage" because
cells are not actively dividing during this time. Which of the following would be a cell that
remains in the GO stage?
a. Cancer cells
b. Liver cells
c. Neurons
d. Epithelial cells
Answer:
G₀ being a stage of the cell cycle that is the resting stage, where there is no cell division, the cells that would remain in the G₀ stage throughout life are the neurons (option c).
Explanation:
In the G₀ phase, considered outside the cell cycle, there is cell metabolic activity but no cell division, since cyclins and cyclin-dependent kinases disappear. Some cells, such as neurons, do not undergo cell division throughout the life of an organism, so they remain in G₀.
In some organs, such as the liver, the hepatocyte may remain in G₀ until the organ receives an injury, and may regenerate by cell division. This is not the case of neurons, which maintain a constant quantity throughout life.
The other options are not correct because:
a. Cancer cells are characterized by a very active and uncontrolled cell division process.
b. Liver cells can remain in G₀, but cell division can be activated when required.
d. Epithelial cells are constantly dividing, since it is a tissue that undergoes frequent cell replacement.
Describe the types of lithospheric plate collisions that build
mountains.
Answer:
When plates collide or undergo subduction (that is – ride one over another), the plates tend to buckle and fold, forming mountains. Most of the major continental mountain ranges are associated with thrusting and folding or orogenesis. Examples are the Jura and the Zagros mountains.

Charlie tested three types of toy cars. He placed the cars on the same starting line on the same inclined plane. He released the three cars at the same time. He measured how far the cars traveled when rolling down the plane, to see which type of car rolled furthest. What is the independent variable in this experiment?
A. the ruler used to measure distance
B. grade of inclined plane
C. type of car
D. Charlie
PLEASE ANSWERR
Answer:
The correct answer is - option C. type of car.
Explanation:
An independent variable in any study, experiment, or research is a factor or variable which is the only factor that is manipulated or changed and directly affects the dependent variable. It is a factor that influences the result with the change in it.
In this case, there are all other factors are constant except the type of cars which is the independent variable as a change in it leads to the change in the distance of rolling.

If A mixture of three amino acids, Asp, Ala and Arg, placed on a cation-exchange resin containing sulfonate (-SO3-) groups will flow down the column at different rates.
a. True
b. False
Answer:
A. True
Explanation:
If A mixture of three amino acids, Asp, Ala and Arg, placed on a cation-exchange resin containing sulfonate (-SO3-) groups will flow down the column at different rates.
This is because amino acids contain varying proportions of elements and compounds . For example, sulphur composition varies and a cation exchange resin will favor the ones with a higher amount of the element.
