Think about how acids and bases would affect the water quality in the two lakes. which set of ph data would you expect to see based on your observations? lake a: ph = 4.5; lake b: ph = 7.5 lake a: ph = 8.3; lake b: ph = 3.7 lake a: ph = 6.6; lake b: ph = 6.8 lake a: ph = 10.2; lake b: ph = 1.7
Answer:
7.5
Explanation:
Its neutral and testless
Water first-rate has significantly laid low with the presence of acid and base within the water. So answer is lake a: ph = 6.6; lake b: ph = 6.8.
The water isn't always precise for fitness whilst its exceptionally acidic or exceptionally basic. If the pH of water is almost impartial, this water is nice for consuming purpose. In the choice 3, each lake A and lake B has pH almost impartial so this water reasons no awful impact at the fitness of the human body. Highly acid water has low water first-rate because of the presence of metals which adversely have an effect on our body.
What is pH of lake water ?The pH degree of the water in rivers, lakes, and wetlands is critical to plant and animal life is 7.
Hence explained.

In an example of pleiotropic genes, the flower color gene studied by Mendel affected ________ trait(s).
Answer:
two traits ,
Explanation:
In an example of pleiotropic genes, the flower color gene studied by Mendel affected a single trait.
Pleiotropy refers to a phenomenon where a single gene influences multiple, seemingly unrelated traits or characteristics in an organism. However, in this specific case of Mendel's flower color gene, it affected only one trait, which is the color of the flower.
Genes are the basic factors of inheritance. They are found in the DNA of all living organisms. They are responsible for transmitting genetic information from one generation to the next and play a crucial role in determining an organism's traits and characteristics.

Which phrase best describes the need for ion channels?
ions must be able to interact with the charged regions of the cell membrane
o ions need to be sheltered from interacting with the charged regions of the cell membrane
Oso nutrients may enter the cell
O so nutrients may exit the cell
Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient. The resulting ionic current, generated by the movement of charged ions through membrane channels, can be measured by patch-clamp methods.
Ion channels must be able to interact with the charged regions of the cell membrane so nutrients can enter the cell.
What are ion channels?
Ion channels are passages in the cell membrane that allow the passage of charged molecules such as
Sodium: Na+Potassium: K+Ions pass from one side to the other of the cell according to the electrochemical gradient. In other words, they go from a place with high concentration to one of low concentration. But to do this, they need to interact with the charged regions of the membrane, which are the ion channels.
Ions channels are one of the ways that nutrients enter the cell.

I took the test and got it right
Why is the percentage similarity in the gene always lower than the percentage similarity in protein.
Answer:
Synonyms in the genetic code exist and some species only use one synonym to get the same amino acid. The reason why the percentage is low in gene is because it does not involve a lot of processes compared to the proteins which undergo mRNA and tRNA to be coded as amino acids.

Would a human with enough food and water and oxygen in a suit survive a full close orbit around Earth? I would think not because of all the space junk, but thats the only reason I can think of.
Explanation:
except that, their first problem is how to drink the water and eat the food provided while at the same time taking in oxygen...
And the close orbit would either pull them towards earth resulting in a collision
or shoot them out of the orbit at insane speeds
in both case they will die..
as soon as they will enter the earth's atmosphere, they will be burned alive by the heat due to the friction between their body and the air around them when they will be in the process of collision.
even if they avoid all this, they will still either be burn to death or freeze to death on either side of the earth coz the suit is only suitable for a limited amount of time...

how does the changing nature of water rights relate to the investigation phenomenon
Answer:
Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents etc. Natural activities taking place in the earth's crust, as well as surface, are the main reasons for these disasters.
We are running out of water due to change in climate conditions like floods, droughts, sea level rising.
Reasons of water running out:Drought- The world’s changing climate has been linked to an increased incidence of droughts that results in increase demand of water supply.Sea level rising- Rising sea level increases the salinity of both surface water and ground water through salt water intrusion.Increasing population-About 70% of the world’s freshwater consumption is for agriculture and food demand is rising.
