Food grain are stored in the blank for future use
Answers
Food grains are stored in the warehouse or granary for future use to maintain the production and supply of food in the country and it is also considered as a security measure for the farmers and government agencies.
The grain storage system is important to preserve the nutritional value of the food grains and avoid the losses incurred due to pests, rodents, and other natural calamities such as floods and droughts.
Food grains are the essential components of the human diet, and they need to be stored with utmost care and caution. The quality of food grains plays a crucial role in ensuring the food security of the country. The farmers and the government agencies take care of storing the food grains in the warehouses, which are usually built in the proximity of the grain-producing areas. These warehouses should be equipped with the latest technologies and tools to ensure the safe storage of food grains.
The government also provides subsidies and financial support to the farmers to build their warehouses to store the food grains. The food grain storage system is crucial for ensuring the continuous supply of food and for the survival of the farmers, especially in the developing countries.

describe how root hairs absorb nitrate ions from soils with low nitrate concentrations?
Answers
Answer:
Roots have specialized cells called root hair cells that are responsible for absorbing water and mineral ions like nitrates from the soil. These cells have long thin projections that stick out into the soil.
For plants to take up mineral ions, ions are moved into root hairs, where they are in a higher concentration than in the dilute solutions in the soil. This movement of ions from a low concentration in the soil to a higher concentration in the plant is achieved through a process called active transport. Active transport is a process that is required to move molecules against a concentration gradient. This means that substances are moved from a low concentration to a high concentration, which is the opposite of what would happen naturally. The process requires energy.
In the case of root hair cells absorbing nitrate ions from soils with low nitrate concentrations, active transport allows the plant to take in the ions it needs from the soil around it. The energy required for this process is produced by respiration.

Controlled variable - the variable that is kept the same during a scientific experiment.
We want to investigate the correlation between the light intensity and the rate of photosynthesis.
We can adjust the amount of light intensity by moving the lamp near or far from the aquatic plant.
We can also measure the amount of gas produced by photosynthesis in one minute.
(1) What is the independent variable in this experiment?
(2) What is the dependent variable in this experiment?
(3) What are the controlled variables in this experiment?
(4) What will be observed if the photosynthesis is happening more slowly?
I (5) What can you conclude from this experiment?
Answers
1. Independent variable = light intensity
2. Dependent variable = rate of photosynthesis
3. Controlled variables a= other variables - independent and dependent
4. Low amount of gas will be produced
5. Light intensity has a correlation with the rate of photosynthesis
Experimental variables in photosynthesisDuring photosynthesis, carbon dioxide and water combine to form carbohydrates in the presence of solar radiation. The process in specific to green plants only and oxygen is evolved as a by-product. The higher the amount of oxygen produced, the higher the rate of photosynthesis.
Independent variables in experiments are the variables supplied directly by the experimenter which can be manipulated to see if it produces any effect or outcome.
The dependent variables are variables that measure the effect of the independent variable.
The remaining variables apart from dependent and independent variables are controlled variables.
From the experiment investigating the effects of light intensity on the rate of photosynthesis, all other things being constant, the more the light intensity, the more the rate of photosynthesis.

Explain how scientists use geologic time to determine the age of landforms.
Answers
Answer:
scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.
Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. The three primary methods are:
Radiation Measurement
Stratigraphic Superposition
The Fossil Record
From these methods of dating, scientists have determined that the earth as we know it seems to be about 4.6 billion years old. It is theorized that the earth got its start as a result of what is called the "Big Bang nearly 6 billion years ago. The Big Bang theory holds that all the planets, stars, solar systems, galaxies, etc., are the result of a huge explosion that sent material speeding through space. As time passed, the gravitational force of larger chucks of material attracted the smaller chunks and formed the galaxies and solar systems we see today.

2. What did the Watson and Crick double helix model of DNA structure
explain about this molecule.
Answers
The Watson and Crick double helix model of DNA structure, proposed in 1953, provided a breakthrough understanding of the molecular structure of DNA, which has profound implications for our understanding of genetics, heredity, and molecular biology.
What is DNA structure?The model explained several key features of DNA:
Double helix structure: The model proposed that DNA consists of two strands that are twisted around each other in a helical fashion, forming a double helix structure. The two strands are held together by hydrogen bonds between complementary nucleotide bases (adenine with thymine, and guanine with cytosine), forming base pairs along the interior of the helix. This explained how DNA can have a stable and structural integrity, while also allowing for the replication and transcription of genetic information.
Complementary base pairing: The model explained how the nucleotide bases in DNA (adenine, thymine, guanine, and cytosine) pair specifically with their complementary bases to form the "rungs" of the DNA ladder. This complementary base pairing mechanism ensures that the genetic information stored in DNA is accurately replicated and transmitted during cell division and protein synthesis.
Antiparallel orientation: The model revealed that the two strands of DNA in the double helix are oriented in an antiparallel manner, meaning they run in opposite directions. This orientation allows for the formation of hydrogen bonds between the complementary base pairs, and it has important implications for DNA replication and transcription processes.

92ml 3.0 fl oz what is the ratio
Answers
The ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
To find the ratio between 92 mL and 3.0 fl oz, we need to convert the units to a common measurement. Let's convert 3.0 fl oz to milliliters (mL).
1 fluid ounce (fl oz) is equal to approximately 29.5735 milliliters (mL).
Therefore, 3.0 fl oz is equal to 3.0 * 29.5735 = 88.72 mL (rounded to two decimal places).
Now we can express the ratio between 92 mL and 88.72 mL:
92 mL : 88.72 mL
Simplifying the ratio by dividing both sides by the greatest common divisor, we get:
46 : 44
So, the ratio between 92 mL and 3.0 fl oz is 46 : 44, or it can be further simplified to 23 : 22.
