Answer:
False
Explanation:
We know more of the moon than we do of our own oceans! There are many, <em>many</em>, organisms on Earth that have not been classified. We have not been able to explore deep in the ocean, extremely cold climates, and some may have even been missed in "our backyard" because Earth is so diverse! According to <em>National Geographic</em>, "Even after centuries of effort, some 86 percent of Earth's species have yet to be fully described, according to new study that predicts our planet is home to 8.7 million species. ... So far, some 1.2 million species are known to science."
Have a nice day!

Answer:
<h2>⭐Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.</h2>
Answer: Examples of genetic variation include eye color, blood type, camouflage in animals, and leaf modification in plants.
Explanation:
Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population. Sexual reproduction promotes variable gene combinations in a population leading to genetic variation.
Answer:
the resting membrane potential will decrease to become slightly more negative
Explanation:
The resting membrane potential refers to the electrical charge difference across the plasma membrane when a cell is at rest (i.e., the cell is in a non-excited state). The resting membrane potential is caused by the electrochemical gradient of ions across the cell membrane and the membrane's permeability to each type of ion. The neuron cell membrane is more permeable to potassium ion (K+) movement than sodium ion (Na+) movement, thereby the resting potential is much close to the equilibrium potential of K+. A neuron at rest is negatively charged. In consequence, if the neuron would become impermeable to Na+ (e.g., by removal of Na channels), the extra efflux of Ka+ would lead to a membrane potential to slightly more negative than the resting value, but this value would remain higher than the equilibrium potential of K+.
