Cells must move materials through the {membrane} and throughout the {cytoplasm} to maintain {homeostasis} Movement of substances is regulated because membranes are {semi} permeable. Membranes are {phospholipid} bilayers that contain embedded {proteins} The cells external environment and cytoplasm are aqueous, meaning that solutes such as {salt}are dissolved in a solvent called {water} Water may travel slowly through the membrane by {osmosis} or quickly through protein channels called {aquaporins}
Answer:
Runoff is one of the ways land water finds its way back to the ocean, so it can join the water cycle again.
Usually, all the water that falls to the land gets soaked in the soil. However, during long rainy periods, or in the spring, when snow and ice glaciers start melting, soil gets oversaturated with water, so this excess water start flowing on the earth's surface. Gravity directs this water from higher to lower areas, where it will flow into some valley river. This river will take the runoff water to another river, then to the sea or the ocean.
Now this water can evaporate and start the water cycle once more.
The Fossil Record. Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. Scientists date and categorize fossils to determine when the organisms lived relative to each other.

Answer:
All of the above are true
Explanation:
Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:
- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.
- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.
Based on this, all of the above options are TRUE
Answer:
The gravitational pull between two objects increases as the distance between them decreases. The gravitational pull also increases with an increase in the mass of the objects. Earth has a large mass. So, when our bodies are close to Earth, the gravitational pull between us and the Earth is strong. This force pulls us down, so we stand firmly on the ground without floating in the air. Without the gravitational force, we would drift away from Earth.
