1. List the major ways in which humans are damaging the environment
2. Floods can devastate an ecosystem, however they can also have a positive impact. Please explain the positive impacts major floods can have on the ecosystem.
3. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
4. Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems.
Answer:
1. The large number of the pollution going into the air becaue of overfarming, and the high demand for unrenewable resources.
2. The positive impacts that floods can have is that they can water plants for places in drought like places such as California. For areas that are vastly dry, rain could be essential to humans, plants and animals in need of it.
3. These changes affect the ecosystem puts the ecosystems in a rather different situation than the ecosystem and those supported by it to adapt to the newcomings occuring of different seasonal changes and much more.
4.
-There can be alternatives to not destroying unrenawable resources.
-Use electrical cars that don't pollute the air.
-Be resourceful with their water and don't use more than needed.
-don't litter.
-recycle.
Describe the use of enzyme for testing glucose in the urine of diabetics
Answer:
If too much glucose gets into the blood, the extra glucose will be eliminated through your urine. A urine glucose test can be used to help determine if blood glucose levels are too high, which may be a sign of diabetes.
What is density of a liquid with mass of 17.4 and a volume of 20 mL ? Would this liquid float or sink at room temperature based on its density and the known density of water?
Answer: The density of the liquid is 0.9 g/mL
. Hope this helps but I can not answer the second part. Hope that it is beneficial to you anyway! :)
(Edit) This might help you figure it out: The relative densities of an object and the liquid it is placed in determine whether that object will sink or float. An object that has a higher density than the liquid it's in will sink. An object that has a lower density than the liquid it's in will float.
Explanation:
Answer:
i think it would float tbh
Explanation:
sorry if it isnt correct i am just trying to help
Need help pls I’m being timed

What landform is created when 1 oceanic plate and 1 continental plate move apart at a Divergent Boundary?
Answer:
Divergent boundaries also form volcanic islands, which occur when the plates move apart to produce gaps that molten lava rises to fill. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary.

Define 3 of the major parts of the skeletal system and list the
function(s) of each (bones, ligaments, and tendon, cartilage.)
Answer:
Bone
The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.
Ligament
Ligaments connect the ends of bones together in order to form a joint. They also assist in holding organs in place. Tendon: A tough, flexible and inelastic band of fibrous connective tissue that connects muscles to bones.
Tendon
A tendon is a fibrous connective tissue which attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
Cartilage
Cartilage: This smooth and flexible substance covers the tips of your bones where they meet. It enables bones to move without friction (rubbing against each other). When cartilage wears away, as in arthritis, it can be painful and cause movement problems.

what is the kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s
Answer:
We can plug in the information for the ball into this equation to determine the kinetic energy. The mass is 0.5 kg and the velocity is 10 meters per second. So: KE = (1/2)(0.5)(10)^2. Thus the kinetic energy of the ball is 25 J

b.The cell loses water by pumping it across the membrane with the use of ATP
c.The cell gains water because there is a higher concentration of water inside the cell.
d.The cell stays the same because water will not move across the cell membrane.
please help me im trying to raise my grade up
Answer: The answer to this question is A
In a balanced ecosystem with predators and prey, if the prey population decreases then....?
Answer:
Predator population will also decrease
Explanation:
This is because the predators are dependent on their prey without the prey they would starve and die out so with less possible food the less of a population for what ever eats that prey which can lead to a chain reaction throughout the ecosystem however it is also the other way around too the more possible food the more chance for babies to be born and not starve to death.

What can happen if a population of organisms disappears from the food chain in an ecosystem with low biodiversities, such as the tundra?
Answer: If the population of an organism dies out, then the animals on top of it on the food chain are going to die, since they will have no other food to rely on. Or, they will have to find a new source of energy if they do not.
This is why we should not try to kill any animals, even too much fishing can cause the same problem.
Hope this helps you!
