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.
what will happen to a population of organisms that are in an environment with little to no oxygen?
Answer:
Hypoxia occurs when algae and other organisms die from lack of oxygen and available nutrients. Hypoxia events often follow algal blooms. The cyanobacteria, algae, and phytoplankton sink to the seafloor, and are decomposed by bacteria. This lack of oxygen creates dead zones in which most aquatic species cannot survive.

Explanation:
Help, needed. Its for a grade and im confused.
Answer:
Point Y
Explanation:
When the ball has the greatest potential energy, it has the most movement/it's at it's fastest. You can easily figure out these questions usually by picking the point that is lowest on these ramps. If two points are at the same level, pick the point that leads from the ball going down the steepest ramp.

usefulness of earthworm
Answer:By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. ... Nitrogen in the casts is readily available to plants.
Explanation:
Earthworms have the ability to eat and mix large amount of soil and organic matter and deposit it in the form of casts. They also enhance incorporation and decomposition of organic matter, increase soil aggregate stability, improve porosity and water infiltration, and increase microbial activity.
before it was known as "science," this branch of study was called what?
Answer:
biology is the correct answer
Before it was known as "science," this branch of study was called Natural Philosophy.
What do you mean by science?The pursuit of knowledge is what is meant by the term "science." This approach describes and provides an explanation for natural occurrences based on observations and experiments. The term "science" can also refer to the arranged body of information that has been accumulated by individuals via the application of that system.
A person who works in a particular field of science and possesses in-depth knowledge about that field is called a scientist. Or, to be more general, anyone who studies or works in a scientific field is considered to be a scientist.

Name the following
he valve presents at the mouth of the pulmonary artery
Explanation:
The pulmonary valve (sometimes referred to as the pulmonic valve) is a valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. It is one of the four valves of the heart and one of the two semilunar valves, the other being the aortic valve. Similar to the aortic valve, the pulmonary valve opens in ventricular systole, when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve.
antigen-presenting cells usually display processed antigens to t cells in the _____________.
Antigen-presenting cells usually display processed antigens to T cells in the LYMPH NODES. These nodes are regions of the body where lymphocytes are activated.
T cells are white blood cells (lymphocytes), which form part of the immune system.
These cells (T cells) develop in the bone marrow.
The lymph nodes are secondary lymphoid organs in which naive T cells that search for specific antigens examine antigen-presenting cells (APCs) for their activation.

why are they assuming the large molecules will stay on their own side of the membrane?
Answer:
What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.
Explanation:
Hope It Helps
It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.
The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.
The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.

what is the approximate percentage of total fixed nitrogen attributed to human activities?
Of the annual global total of fixed nitrogen, human activities account for roughly 45%.
Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.
Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.
