How come the human body does not absorb water completely? In other words; why is it that even though the water could be the best possible in terms of purity, the kidneys still need to filter it? What is there to filter if the water is completely clean and pure? Shouldn't all that water simply be absorbed by all the cells in our organism?
Answer:
Because it's job of kidney to filter out everything passing through it.
Explanation:
logical answer:
it's the job of kidney to filter every thing which oasses through it. How can your kidney know that the water you had drink is pure . Does your kidney have brain ?? likewise nothing is 100% perfect in this world , the water you drink is also not 100% pure.
Knowledgeable Answer:
Human body doesn't absorb all water completely because some water is filtered from our kidney to maintain overall fluid balance,to
regulate and filter minerals from blood, to
remove waste material and toxic substances. and it's the function of kidney to filter everything hich passe through it and if it stop filtering then human body doesn't work properly.

Next, you’ll build a simulation based on what you think will happen because of natural selection.
Here are two considerations:
Some individuals with harmful characteristics can still successfully reproduce, but they have an overall lower chance of doing so compared to organisms with neutral or beneficial traits.
Natural selection may affect distribution of traits. It’s possible that harmful traits could eventually disappear from the gene pool.
Don’t worry about precise population numbers. Based on your understanding of natural selection, you’ll be modeling only one scientifically plausible trend that can occur. There are several correct variations of this diagram. You’ll explain the justification for your choices in part E.
Assume that these plants have a life expectancy of about one year, but the rate of reproduction keeps their population consistently around 2,500 organisms. Using the same elements you used in part C, draw simulations for year 5 and year 10. Clearly label each simulation.
According to natural selection process, the trend that will occur is that the number of organisms with harmful characteristics will decrease while organisms with neutral or beneficial traits will increase in the plant population
What is natural selection?Natural selection is the process by which organisms with favorable features and characteristics that enable them to adapt to their environment survive while those with unfavorable traits die off.
In a changing environment, it will be observed that the organisms with the most favorable traits will be the most dominant in the environment.
Therefore, for the Year 5 and Year 10, the most likely trend that will occur is that the organisms with harmful characteristics will be decreasing in the plant population while organisms with neutral or beneficial traits will likely be increasing in number.

Explanation:
what is vegetative propagation?? explain in detail
Plant development from vegetative components such as stems, roots, and leaves is known as vegetative propagation.
Plants, unlike most animals, may be propagated by extracting a portion of tissue (usually a leaf, stem, or root) from a parent plant and cultivating it in perfect conditions. Remove a little growing tip off an apple tree limb and plant it in moist soil in a warm, semi-humid region, for example. It will become a new plant when the branch grows roots.
Reasons for vegetative propagation:
Preserving characteristics Vegetatively propagated plants are clones of their parents. They share the exact same DNA. As a consequence, they will grow in the same pattern, blossom in the same color, taste the same, be disease resistant, and so on. In reality, if you enjoy an apple tree, the only method to increase its number is to reproduce it vegetatively*. Seedlings will be connected to their parents but will most likely have numerous different characteristics.Ease Rooting clippings from a parent plant is simple and inexpensive. Collecting seeds on contract might be time intensive.The downside:
Lack of diversity An orchard of clones, as one might expect, is far more sensitive to diseases and stress; if one plant becomes ill, they all get ill. When plants reproduce through seeds, their DNA is mixed, resulting in new variants. Genetic diversity ensures that at least one plant will survive and continue to reproduce.VEGETATIVE PROPAGATION -:

C- layer of the atmosphere, rich in ozone gas, that protects the Earth's inhabitants from the harmful effects of UV radiation
D- layer of gas at the bottom of the ocean that bubbles off when disturbed
Answer:
the answer is c
Explanation:
pretty simple
The ozone layer is best described as a layer of the atmosphere, rich in ozone gas, that protects the Earth's inhabitants from the harmful effects of UV radiation. The correct option is C.
The ozone layer is found in the stratosphere, a region of the Earth's atmosphere located approximately 10 to 50 kilometers above the Earth's surface.
It contains a higher concentration of ozone (O3) molecules compared to other parts of the atmosphere.
The ozone molecules in this layer absorb a significant portion of the incoming UV radiation from the Sun, thereby shielding living organisms on Earth from its harmful effects.
UV radiation can be harmful to human health and ecosystems.
Overexposure to UV radiation can cause sunburn, skin cancer, cataracts, and immune system suppression in humans.
Thus, the correct option is C.

Answer:
destruction of natural habitats
Explanation:
First let's define our main terms or each answer choice.
1)Decreased deforestation - Deforestation is the action of clearing mass amounts of trees for human use such as farms, buildings, houses etc. So this answer is basically saying that as the human population increased the amount of trees that get destroyed will decrease.
2)Destruction of natural habitats - Natural habitats is simply the natural home of animals. So this answer is saying as the human population increases the more number of animals natural homes will be destroyed
3)Unchanged climate - Climate is basically the long term weather of an area. So this answer choice is saying that as the human population increases the climate will remain unchanged.
4)Increased biodiversity - Biodiversity is the different kind of life on earth usually regarding a specific habitat or ecosystem. So this answer choice is essentially saying that as the human population increases the types of life on earth increases.
What comes with increased human population?
As the human population increases the need for food, houses, water, jobs etc increases as well. Keep that in mind while looking at the answer choices.
Determining the answer
Why the answer isn't A
Rereading 1) and then what comes with increased human population we can most definitely rule out A. As human population increases the need for houses and jobs increases. In order to have a good enough supply of wood and land for these houses and buildings for these jobs, deforestation must occur. So as human population increases deforestation would increase as well.
Why the answer is B.
Rereading 2) and then looking at what comes with increased human population we can maybe say that B is correct. Looking back at the previous section we've already identified that mass deforestation must occur to satisfy the needs for wood and land for houses and jobs for the increased population. As we know many animals probably live in these forests and inside of the trees so many of these animals homes would be destroyed resulting in the destruction of natural habitats ( animals homes )
Why the answer isn't C
After rereading section 3) and what comes with increased human population we can rule out C. If an increase in human population results in deforestation the amount of CO2 released into the air increases as well. If you didn't know trees absorb CO2 which is bad for the atmosphere. Once destroyed the trees release the CO2 that they have absorbed. CO2 and other green house gases create holes in our atmosphere leading to a change in climate as the suns radiation travels through these little holes. This results in a change in temperature, increased natural disasters and the melting of ice on the poles which also leads to increased temperatures. Deforestation isn't the only cause of this ( gasoline from cars, burning of fossil fuels , pesticides and many other human caused actions result in this ). These are all human caused things so if the human population increases the amount of green house gase emissions would likely increase as well meaning the climate would no remain unchanged.
Why the answer isn't D
After reading section 4) as well as the section titled "why the answer is B" we can rule out D. In order for an increase in biodiversity to occur, natural habitats must be preserved ( remain untouched ) if deforestation occurs then natural habitats will be destroyed and biodiversity will never increase as many animals may not be able to find another sustainable habitat. Not only that but the question asks about a negative affect and biodiversity is a good thing.
