The nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

Every cell in the body has a nucleus, except for mature erythrocytes (red blood cells). While some cells contain more than one nucleus such as skeletal muscle and some other cells contain several nuclei.

The nuclear envelope surrounds the nucleus. i. e. largest organelle of the cell. It has a similar structure to that of

the plasma membrane. But the nuclear envelope contains tiny pores that allow a few substances to pass between it and outside the cytoplasm, i.e. the cell contents excluding the nucleus.

Therefore, the nuclear envelope is perforated with pores to allow it to move in and out of the nucleus.

To know more about the nucleus, refer to the below link:

Nata [24]

According to the history and physical examination of the patient, the patient may have a upper gastrointestinal bleed most probably from a bleeding peptic ulcer. A bleeding peptic ulcer can cause abdominal pain and vomiting described as coffee ground vomit because of the reaction of the blood with the stomach acids. The patient's vital signs signify that the patient is in the state of hypovolemic shock. The emergency medicine consultant should use an oxygen mask with caution because additional vomiting episodes may recur and if the patient is wearing an oxygen mask, the vomit cannot be cleared thoroughly and may even cause aspiration.

A hypothesis is a possible answer to a scientific question, but it isn’t just any answer. A hypothesis must be based on scientific knowledge, and it must be logical. A hypothesis also must be falsifiable. In other words, it must be possible to make observations that would disprove the hypothesis if it really is false.

HOMER NOTICES HIS SHOWER IS COVERED IN GREEN SLIME. hI8S FRIEND BARNEY TELLS HIM COCONUT JUICE WILL GET RID OF THE SLIME. HOMER

Orlov [11]

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.
