Answer:
1. the cause of magnetic pole reversals
2. the year the next magnetic reversal will take place
4. the exact location of the next earthquake along the California coast
Explanation:
Due to magnetic striping patterns, the magnetic pole of earth go in reverse direction. When the magma comes out from the ocean floor so it spreads on the ocean floor making new bands. So these new bands that spreads the ocean floor make a new floor which change the polarity of the ocean floor in opposite direction. Due to this magnetic striping, the magnetic reversal will take place in which polarity of the earth crust reverses.

Please Help Me: Why would water have to be present on Earth before life?
Answer:
cells have processes that must be carried out like respiration etc that requires a transfer of material from cell to cell or within the cell therefore water is a medium for this transfer
Water would have to be present on earth before life because it is one of the main constituents of cells as well as its membrane.
What is the function of water in living cells?The function of water in living cells is that it acts as a solvent in order to assist cells in transport and utilize substances like oxygen or other significant nutrients.
It is necessary to have water before the imagination of life on the earth's surface. This is already mentioned that water is essential for all metabolic activities, cell transport, etc. Water is extremely filled in the cell's cytoplasm and delivers important cellular functions.
Apart from this, the majority of living beings need water to eliminate thirst as well as other physiological processes.

Explanation:
The endomembrane system (endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins. It includes a variety of organelles, such as the nuclear envelope and lysosomes, which you may already know, and the endoplasmic reticulum and Golgi apparatus, which we will cover shortly.
Although it's not technically inside the cell, the plasma membrane is also part of the endomembrane system. As we'll see, the plasma membrane interacts with the other endomembrane organelles, and it's the site where secreted proteins (like the pancreatic enzymes in the intro) are exported. Important note: the endomembrane system does not include mitochondria, chloroplasts, or peroxisomes.

Laboratory aprons are often required during lab activities. Your instructor will tell you whether it is mandatory or not. True False
Answer:
True
Explanation:
Before students can begin work in a laboratory, they would need proper orientation on the dos and don'ts in the laboratory. The orientation is important because the laboratory is a place where serious work is done and which houses chemicals that could be dangerous when not handled properly. The orientation is provided by an instructor who among other things explains to the students why an apron is important and should be worn at all times during laboratory activities.
The laboratory apron is important as it protects people in the laboratory against corrosive materials. It is also designed in a way that it can be easily pulled from the wearer when an accident occurs. After this orientation the students would not have to be reminded everyday by the instructor about the importance of laboratory aprons.
It is true that laboratory aprons are often required during lab activities. Your instructor will tell you whether it is mandatory or not.
When performing lab work, aprons are frequently needed to protect the wearer's clothing from possible spills, splashes, or chemical exposures.
The particular requirements for donning a lab apron, however, could differ based on the lab, institution, or type of experiment being carried out.
In order to determine whether or not a laboratory apron is required for a given lab activity, the instructor or lab supervisor is the reliable source.
To ensure safety and compliance with the unique procedures of the laboratory, it is crucial to adhere to the directions and guidelines given by the teacher.
Thus, the given statement is true.
