Explanation:
Mitosis and endocytosis are two fundamental cellular processes essential for maintaining a eukaryotic life. Mitosis partitions duplicated chromatin enveloped in the nuclear membrane into two new cells, whereas endocytosis takes in extracellular substances through membrane invagination. These two processes are spatiotemporally separated and seemingly unrelated. However, recent studies have uncovered that endocytic proteins have moonlighting functions in mitosis, and mitotic complexes manifest additional roles in endocytosis. In this review, we summarize important proteins or protein complexes that participate in both processes, compare their mechanism of action, and discuss the rationale behind this multifunctionality. We also speculate on the possible origin of the functional reciprocity from an evolutionary perspective.

Question 3 (1 point) When using the correlational research design, researchers report a number called the "correlation coefficient" This number indicates strength & direction of the relationship between two variables and falls between -1 and +1. Choose the correlation coefficient that demonstrates a moderate relationship showing fewer depression symptoms in people who report higher community engagement? a) -0.61 b) -0.19 c) +0.17 d) +0.61
The correlation coefficient that demonstrates a moderate relationship showing fewer depression symptoms in people who report higher community engagement is +0.61. That is option D.
What is correlation coefficient?Correlation coefficient is a measure that is used statistically to know the extent of change that can be brought about on a variable through the change of another variable that is related to it.
The correlation coefficient is measured by dividing the covariance by the product of the two variables' standard deviations.
This number indicates strength & direction of the relationship between two variables and falls between -1 and +1.
There are various types of correlation coefficient which are the negative correlation coefficient and the positive correlation coefficient.
An example of a positive correlation coefficient is +0.6 which shows that there are fewer depression symptoms in people who report higher community engagement.

You observe two beakers containing clear liquid and ice cubes. In the first beaker, the ice cubes are floating. In the second, the ice cubes are on the bottom of the beaker. Write a hypothesis to explain the difference in your observations about the two beakers.
When water freezes into ice the hydrogen bonds formed allow them to be spaced farther apart, making them take more space and the overall density decreases, so ice float in the water.
What is density ?The density of can be referred as the mass per unit volume which means the ratio between mass and volume, where how much stuff an object has in a unit volume.

Question 1 of 10 The diagram shows a plant cell. 1 2 3 4 Which label points to the location in the cell where the first step of cellular respiration occurs?
The location in the cell where the first step of cellular respiration occurs is 2, i.e., a mitochondria. The correct option is B.
What is mitochondria?The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular).
Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).
Because they assist in cellular respiration, the process by which energy is extracted from food, mitochondria are known as the powerhouse of the cell or energy manufacturers.
The first stage of cellular respiration, known as glycolysis, takes place in the cytoplasm of the mitochondria.
To produce cellular energy, the six-carbon sugar molecule of glucose is broken down into three-carbon molecules during the process known as glycolysis.
Thus, the correct option is B.
