What is the appropriate control for an experiment on the effect of nitrate fertilizer on germination of sunflower seeds?
Umm...NOT putting nitrate fertilizer on the seeds in a second planting? Apparently they're not teaching the scientific method in science class any more, so let's set this experiment up properly. You want to test the effect of nitrate fertilizer on sunflower plants. You will need: some plantable sunflower seeds--go to a garden center for these. I saw a kid try a sunflower growing experiment once. He planted seeds and they didn't grow. The teacher asked him where he got the seeds..."at Torchie's." Torchie's was a gas station, and he bought roasted sunflower seeds. Those won't grow at all. Anyway, you can't go to Torchie's anymore because Mr. Torchie sold his store to someone else. But don't go there anyway. some potting soil. two planting trays. some nitrate fertilizer. two watering cans. Label one "with fertilizer." Plant the same number of seeds in both trays in soil from the same bag. Label one "with fertilizer" and one "without fertilizer." Just water the "without fertilizer" tray. Use fertilizer according to directions on the label on the "with fertilizer" tray. Except for the fertilizer, don't do anything different--put them in the same window, make sure the cat doesn't get in either tray, don't give any other reason for one tray to grow better than the other. Keep records of which one grows better. This is a good, easy, fun experiment.

What are 3 patterns in the world?
Fibonacci sequence: Found in nature, such as the spiral arrangement of sunflower seeds and the branching of trees. Wave patterns: Seen in ocean waves, sound waves, and electromagnetic waves. Fractal patterns: Repetitive mathematical patterns found in shapes like snowflakes, clouds, and mountain ranges.
Which crops can grow in alluvial-soil?
Crops such as rice, wheat, maize, barley, and vegetables like spinach, lettuce, and carrots can grow well in alluvial soil due to its high fertility and good drainage properties. This type of soil is rich in nutrients and supports the growth of various agricultural crops.
What plant is tilted on it's side 98 degrees?
A sunflower is known for turning its head to face the sun, a behavior known as heliotropism. It is common for sunflowers to tilt or lean in different directions, but not typically to the precise angle of 98 degrees.
Names of flowers that start with the letter J?
Jaborosa Jacaranda Jacquemontia Jamesia Jancaea Jasione Jasminum (jasmine, jessamine) Jatropha Jeffersonia Jovellana Jovibarba Juanulloa Jubaea (Chilean wine palm) Juglans (walnut) Juncus (rush) Juniperus (juniper) Justicia hope i helped. :]
Will saturated oils decolourise bromine?
Yes, saturated oils like coconut oil or palm oil will decolourize bromine because the double bonds in unsaturated oils are required for the bromine addition reaction that causes discolouration. Saturated oils lack these double bonds, so they will not react with bromine in the same way.
Do sunflower seeds need scarification to germinate well?
No. The common sunflower does not require scarification; they have a sufficiently high germination rate without cracking the hull.
What role does hypotheses play in scientific inquiry?
If you mean in an experiment then experiments are caused when you ask a question and try to find an answer. The hypothesis is the question you ask such as: Will fertilizer make a Sunflower grow faster? Hope that helped (P.S.) If scientific inquiry is something different than a scientific experiment= I'm sorry I didn't realize:(
Name a few seeds which undergo epigeal germination?
Some seeds that undergo epigeal germination include beans, peas, peanuts, sunflower seeds, and most types of dicot plants. In epigeal germination, the cotyledons are pushed above the soil surface as the seedling emerges.
Is a sunflower seed a dicot?
Yes, a sunflower seed is a dicot. Dicots are plants that produce seeds with two cotyledons, which are the first leaves to emerge from the seed upon germination. Sunflowers belong to the Asteraceae family, which is a group of dicot plants.
What season does sunflowers die in?
Yes and no. There is no specific day on which the sunflower will die, such as "The sunflower will die exactly 120 days after germination." However, the plant will deteriorate in health after it has flowered. and the plant will die when temperatures drop below 29 °F.
Does cowpea undergo epigeal germination?
Well, hello there! Cowpeas, like many legumes, undergo hypogeal germination, where the cotyledons stay below the ground. This process helps protect the delicate cotyledons as the seedling emerges, allowing it to grow strong and healthy. Just like a happy little seedling reaching for the sun, cowpeas follow their own beautiful path of growth.
Which experiment most likely has greater reliability between sunflower growth affected by hardness of the soil or water affecting the growth of cacti?
The experiment on sunflower growth affected by the hardness of the soil is likely to have greater reliability because soil properties can be controlled more easily than water conditions which can be influenced by various external factors. Additionally, soil hardness can be measured more objectively and consistently compared to the impact of water on cacti growth which can be affected by a wider range of variables.
How can I determine if sunflower seeds are suitable for planting?
To determine if sunflower seeds are suitable for planting, you can perform a germination test. Place a few seeds on a damp paper towel and keep them in a warm, sunny spot. Check after a few days to see if they have sprouted. If a good percentage of the seeds have sprouted, they are likely suitable for planting.
Do sunflower seeds come from sunflower?
Sunflower seeds. Sunflower seeds. Sunflower seeds. Sunflower seeds. Sunflower seeds. Sunflower seeds. Sunflower seeds. Sunflower seeds. Sunflower seeds.
Does tap water help sunflower seeds grow?
yes, tap water help sunflower seeds grow because in my honors biology class, we had to see which liquids can germinate sunflowe seeds and tap water was the one that germinated sunflowe seeds to grow...germination is when the stem grows out of the seed...soo i hope i helped youuu with my answerr
How can I revive a dying sunflower plant?
To revive a dying sunflower plant, ensure it receives adequate sunlight, water it regularly but avoid overwatering, provide nutrient-rich soil, and remove any dead or damaged parts of the plant. Additionally, consider using a fertilizer specifically designed for sunflowers to help promote growth and health.
