occurs? Is energy required?
Answer:
water will move out of the cell,energy is required
Explanation:
water moves through osmosis which is the movement of water molecules from a region of higher concentration to a region of lower concentration.

would need to be kept the same for all the plants, in order to make the investigation a
fair test.
1.

3
Answer:
1: Periods of Light
2:Temperature Substrate
3:Soil Type
Explanation:
Plants use magnesium ions to make chlorophyll in their leaves. Like in nitrate deficiency, the plant is limited in terms of its photosynthetic ability and the plant growth is compromised. Magnesium is a limiting factor in healthy plant growth.
Kim's Dalmatian, Tigger, always eats the same brand of food. Although he does everything else at lighting speed, he is a very slow eater. After watching a TV commercial touting the irresistible taste of Puppy Yums Dog Vittles, Kim decides to conduct an experiment comparing Tigger's regular food (K-9 Crunchy Bits), Puppy Yums Dog Vittles, and a store brand that cost 1/3 as much as the advertised food. Kim gave Tigger the same quantity of each different food, on three successive evenings, and used a stopwatch to determine Tigger's dinner-time munching speed.
Hypothesis:
Predicted Results:
Independent Variable:
Dependent Variable:
Control Variable:
The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.
An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.
In this experiment;
The independent variable is the type of dog foodThe dependent variable is the eating time of the dogThe predicted result is that the dog will eat the advertised Puppy Yums Dog Vittles faster than the other dog foodsThe control variable is the quantity of dog food given to the dog each evening.The hypothesis of the experiment is that the dog will eat the advertised tasty food faster than it eats its regular food.Learn more: https://brainly.com/question/22824409
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.

How might photosynthesis account for seasonal changes in carbon dioxide in the atmosphere? ( for example, why might carbon dioxide levels be highest in May but lowest in October? )
Answer:
When plants are growing, photosynthesis outweighs respiration. As a result, plants take more CO2 out of the atmosphere during the warm months when they are growing the most. Levels of carbon dioxide in the atmosphere rise and fall each year as plants, through photosynthesis and respiration, take up the gas in spring and summer, and release it in fall and winter. Now the range of that cycle is expanding as more carbon dioxide is emitted from burning fossil fuels and other human activities.

mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. The process of making mRNA from DNA is called transcription.
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.

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.
