Answer:
It's due to hereditary
Explanation:
Hereditary Is something that is passed on from family generations. It can pass on genes and disease's. From past family members in blood lines.
Example: My grandpa had cancer but my mom and dad did not but I still have his blood and when I'm 30 I get diagnosed with cancer and die 1 year later.

Opinion: is our current water use sustainable? Why or why not?
Answer:
This actually depends, since most of our water is filtered (depending on where you live) then yes it is sustainable! But if our water wasn't filtered then no, it would not be sustainable. This is because of all the things that go into our water before it's filtered. We've got plastic, trash, dead fish and all that, in some cases sewer system drainage and a lot more that goes into the filtered water that we drink.
Explanation:
A block of aluminum has a mass of 40.5 grams. If the density of aluminum is 2.7 g/mL, what is the
volume of this block?
Answer: 15 mL
Explanation:
Volume = Mass ÷ Density
= 40.5 g ÷ 2.7 g/mL
= 15 mL
∴ the volume of the block of aluminum is 15 mL.

Hi guys can you please help me with number 3 a and b please..ASAP
PLEASE BE RELEVANT AND REAL ANSWERSSS ..I REALLY NEED THIS TO GRAD
Answer:
Okay so for A the thing that is wrong with this experiment is that Cindy has done quite a few things incorrectly. Firstly what her experiment was about. Being healthy is a good thing but then turning around and doing the exact opposite for a week can damage your body. Secondly, Running 4 miles after school is good but then for the next week she sits and watches tv for 3 hours. It doesn't make sense on how she measured her experiment. Cindy should have recorded the times when she ran four miles and then used the same time to watch Tv for the next week.
We can fix this experiment by maybe taking out the hot Cheetos from it as that's just not healthy. Secondly we can have Cindy record how many minutes/hours she ran in the 4 miles and use those same times to watch Tv so that it's even.
Explanation:
For part B firstly it's just not possible to predict the weather with your feet. Secondly your grandpa could easily lie and tell you their hurting or they could just always be sore. Lastly, His feet could be not sore and it still rains.
We can fix this experiment by may be doing something more realistic. But to stay on this instead of calling him you should maybe stay over so that in the morning you can tell whether or not his feet are sore then record for the rest of the day to see if it rains or not. If their not sore and it rains then we know he can't predict weather with his feet the same goes for if they were sore and didn't rain.

Each X shows the location of an archer's arrow on a bull's-eye target. The archer was aiming for the center circle. X xx X x x Which words best describe the archer's results?
Low precision and low accuracy best describe the archer's results. So the correct option is A.
Who is an archer?Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.
With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.
Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.
Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.
During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.
Therefore the correct option is A.

Which of the following steps is required before biological processes can break down organic material in wastewater?
Aeration basins
Primary clarifiers
Filtration
Disinfection
The following steps required before biological processes can break down organic material in wastewater is Aeration basins and Primary clarifiers.
Water treatment refers to any technique that enhances the quality of water in order to make it suitable for usage by humans in homes and offices.
There are certain processes involved in the treatment of water. These includes:
screening and pumpinggrit removalprimary clarifiersaerationsecondary clarifiersFiltrationDisinfectionoxygen uptakeIn the screening and pumping process, materials and objects are removed from the entering wastewater using screening machinery. The extracted material is cleaned, crushed, and disposed of in a landfill.
In the grit removal, fine particle materials are eliminated from the wastewater.
Enormous circular tanks are known as clarifiers that receive the materials. Settled material acknowledge as primary sludge, is pushed to the tank's bottom, while the wastewater leaves from the top.
At the aeration stage, the wastewater receives the majority of its treatment. Pollutants are absorbed by microorganisms and turned into cell tissue, H2O, and nitrogen through biological breakdown processes.
The water treatment process was ended with filtration and disinfection to enable the water to be free from bacteria.
Therefore, we can conclude that the steps required before biological processes can break down organic material in wastewater is Aeration basins and Primary clarifiers.

Please help with answer 3 :)
Answer:
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.
