Help pleasseeeeeee Condensation helped to form early oceans when water vapor in clouds begin to cool. The temperature on early Earth was important to the early oceans. What would have happened if the temperature of early Earth had heated significantly soon after the oceans formed?

The water in the ocean would have evaporated.
The water in the ocean would have undergone sublimation.
The water in the ocean would have percolated down into the soil.
The water in the ocean would have undergone evapotranspiration.

Answers

The correct answer is option A

The water in the ocean would have evaporated. Condensation was the reason for the formation of clouds and rain at that time. The temperature at that time was in the favor for the formation of ocean. Then, the ocean was formed and if the temperature could have increased soon after the oceans were formed. The water could have evaporated from the oceans.
The water in the ocean would have percolated down into the soil.

Why is DNA called semi-comparitive

Answers

DNA is called semi-comparitive because each helix that is created has one strand from the helix which is why it is copied

Which organelle modifies, packages, and sorts proteins for secretion or use within the cell? A)           Golgi apparatus
                B)            lysosome
                C)            endoplasmic reticulum
                D)           nucleus

Answers

Golgi apparatus does this

Final answer:

The Golgi apparatus is the organelle that modifies, packages and sorts proteins for secretion or use within the cell. It processes proteins produced in the endoplasmic reticulum and is involved in their delivery.

Explanation:

The organelle that modifies, packages, and sorts proteins for secretion or use within the cell is the Golgi apparatus. This cellular structure is key in the processing of proteins produced in the endoplasmic reticulum. Proteins are transported from the endoplasmic reticulum to the Golgi apparatus, where they are modified (such as by the addition of carbohydrates to form glycoproteins), packaged into vesicles, and sorted for delivery either to other parts of the cell or to the cell membrane for secretion.

What is one of the negative consequences of dumping waste in landfills?A. It releases toxic fumes.
B. It causes increased transpiration.
C. It can pollute the groundwater.
D. It increases soil bacteria.

Answers

C. It can pollute the groundwater.
The answer is C, it can pollute the groundwater which is a major source of freshwater. Groundwater is also one of our most important sources of water for irrigation. Unfortunately, groundwater is susceptible to pollutants. Groundwater contamination occurs when man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use.
