Answer:
As the concentration of hydrogen ions in a solution increase, the more acidic the solution becomes. As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. ... Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls, and vice versa.
Thank you
7. Observations and inferences are
important in science. How would you
explain the difference between the
two words?
Hey there! I'm happy to help!
Observations are things that can be written down or described. You can observe something with any of your five senses: you can see what color something turns, you can hear the noise something makes, you can taste a cookie with a different amount of an ingredient, you can smell an odor produced by a chemical reaction, and you can feel the texture of different samples.
You can also create observations by using scientific tools. For example, instead of feeling if water is hot or cold, you could use a thermometer. This will give you numerical data which can be put into a table or graphed for further analyzing.
Inferences are created from observation. You cannot make an inference without observation. Observations lead to inferences. Inferences are conclusions or guesses made from the observations. You could infer that sugar makes a cookie taste sweeter after experimenting with no sugar and observing that it tasted bitter. You could infer that more weight allows things to travel further after going down a ramp after measuring the distances different weights travel, graphing it, and observing the data.
Have a wonderful day and keep on learning! :D

About how many times thicker is a
cell wall compared to a cell
membrane?
A. about twice as thick
B. about five times as thick
C. about half as thick
D. up to 100 times thicker
Explanation:
I think it's up to 100 times
A barrier enclosing the cell, the cell wall is located outside the plasma membrane. The plasma membrane can be up to 100 times thinner than a cell wall, hence option D is correct.
What is a cell wall?Cellulose, a polysaccharide sugar that gives the cell wall strength, makes up the majority of its composition.
The leaf blades of L. perenne and T. repens and the stems of Z had the thinnest cell walls (0–9 m) and the thickest (2–0–3 m) among the cells classified as thick-walled.
Compared to gram-negative cells, gram-positive cells have substantially thicker cell walls. The typical thickness of the gram-positive cell wall is 20–80 nm, whereas the typical thickness of the gram-negative cell wall is 5–10 nm.
Therefore, the cell wall is up to 100 times thicker compared to a cell
membrane, hence option D is correct.

if your leg was to get cut off where would you feel the pain?
The thigh area will feel much more pain as when leg is cut off , all nerves are together in thighs, so more pain will be there.
Hope it helps you... pls mark brainliest if it helped you
Answer:
The nerve(s) in your leg.
Explanation:
It's not your leg that will hurt but the nerve in your leg. So wherever the leg is cut, the nerves will have to be cut as well, but also after one of your limbs is amputated, you may feel like the limb is still there. That's called phantom sensation. You might feel pain in your limb even though it is physically not there.
As an ecosystem goes through succession, which of the following is likely to
happen:
A. Increase in biodiversity
B. Ecosystem will trigger Secondary Succession
C. Decrease in competition
D. Decrease in niches
Answer:
A
Explanation:
succession is replacement of one ecosystem by another so this cause increase in biodiversity
When an ecosystem goes through succession, the biodiversity of the ecosystem tends to increase. Thus, the correct option is A.
What is Succession?Succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Succession is always taking place by a better competitor. The first arrived species is known as the Pioneer species. Intermediate species are known as seral communities, while the highest species is known as the Climax species.
Overall, it increases the biodiversity of the region.
Therefore, the correct option is A.

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.
Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.
Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.
The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.
Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.
The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.
