3. How can diversity within an ecosystem be compromised?
O by regulating human activity within an ecosystem
O by helping to maintain habitats that have been disturbed
O by building structures on natural habitat areas
O by leaving the ecosystem alone to fend for itself
Answer:
O by building structures on natural habitat areas
Explanation:
The diversity within an ecosystem can be compromised by building structures on natural habitat areas.
An ecosystem is part of the environment made up of living and non-living components in their natural habitats.
Diversity entails variations in the life forms within a particular ecosystem. When human-induced pressure begins to impact the environment, diversity is threatened Nature has its balancing effect the allow for a wide range of organisms to thrive. When human builds structures, part of the natural habitat is lost.Answer:
building structures on natural habitat areas
Explanation:
contrast ionic covalent bonds. what happens to the valence electrons how does it affect the elements/compounds
Answer:
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... To form a covalent bond, one electron from the halogen and one electron from another atom form a shared pair.
Why does the moon have a effect on the sea?
will give BRAINLIEST and a thank you!
Answer:
The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides. ... High tides and low tides are caused by the Moon give me brainliest

What do ocean waves and
currents have to do with energy waves and
electrical currents?
Answer:
they are both waves and currents
Explanation:
gl studyinggg
Ocean waves, currents, and energy although both waves and electrical currents involve the movement of energy, they are distinct phenomena that occur in different mediums and generate electricity in different ways.
What is the significance of the ocean waves?Ocean waves are caused when the wind blows or passes over the surface of the water, which leads to the generation of larger waves and these waves transfer energy through the ocean's water, which can be used to generate electricity using wave energy converters. They are caused by a variety of factors, including differences in water temperature and salinity, the rotation of the earth, and winds etc.
Hence, ocean waves, currents, and energy although both waves and electrical currents involve the movement of energy, they are distinct phenomena that occur in different mediums and generate electricity in different ways.

Using the genetic code, which of these events can happen?
mRNA can be made into tRNA.
DNA can be made into mRNA.
RNA can be copied before mitosis.
A polypeptide can be made into mRNA.
Answer:
...
Explanation:
.The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
Why enzymes are necessary to maintain homeostasis?
Answer: Enzymes are proteins that catalyse (speed up) vital chemical reactions inside the body. ... If any conditions are outside their specific range then the enzymes cannot function. This could cause the organism to die.

Three students were working on a drawing of the water cycle for a class project. They each had different ideas about what needed to be in their drawing to show the water cycle. This is what they said
Who do you agree with the most?
A)Van: There always has to be a body of water in a water cycle diagram. It doesn't have to be an ocean. It can be an ocean, lake, river, pond, stream, or other body of water
B)Lamar: A water cycle diagram doesn't have to have a body of water. We can draw it without an ocean, lake, river, and, steam, or other body of water
C) Rema: There has to be an ocean in a water cycle diagram.
Answer:
I agree with A, Van.
Explanation:
I agree with Van because I have personally seen water cycle diagrams without the ocean. Another reason why I agree with Van is because in some areas in the world, the ocean isn't anywhere near close to said areas.

What distance would be covered in 10
minutes by a train that travels at a constant
speed of 500 meters per minute?
Answer:
The correct answer would be - 5000 meter or 5 kilometers
Explanation:
Given:
Speed = 500 meter/minute
Time = 10 minutes
Distance would be covered = ?
Formula used:
speed = distance/ time
then, Distance = speed*time
Solution:
Putting values in the provided formula:
Distance = speed*time
distance = 500*10 meters
= 5000 meters or 5 kilometer (1000 meter = 1 kilometer)
Animal cells are placed in an isotonic solution. THEN, additional amounts of solute are added to the solution. What happens to the cells
Answer:
The animal cell will shrink due to loss of water to the external solution
Explanation:
An isotonic solution is that solution which has equal concentration with its external environment. Hence, no net movement of water occurs in an isotonic solution since there is no concentration gradient. Therefore, if an animal cell is placed in an isotonic solution at first, no net movement of water occurs because the intracellular and extracellular concentrations are at equilibrium.
However, if more solutes are added to the solution, it makes the solution HYPERTONIC to the cell i.e greater in concentration. This creates an osmotic gradient and causes water to move out of the animal cell into the solution in accordance to osmotic principles (movement of water from a low concentration of solute to high concentration of solute). This causes the animal cell to likely SHRINK.

Dark surfaces become warmer because they absorb more of the incident radiation. Light-colored surfaces reflect more of the incident radiation, hence absorb- ing less radiation. The higher the absorption, the warmer the temperature.
Explanation:
Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish
Answer:
Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.
Explanation:
Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.
According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.
Write a short essay on a local natural resource that is mined in your region and the uses that come from this mineral. List ways in which the environment is affected by resource extraction.
