HELP PLS Danielle lives with her family on a farm. In school, she has been learning about the nitrogen cycle in science class. She knows that her father spread a nitrogen-based fertilizer on a patch of grass recently where the cows graze in the field. Why was it necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass?

a.because nitrogen can only be “fixed” by lightning
b.because there are no decomposers on the farm
c.because bacteria released all of the nitrogen into the air
d.because plants cannot use “free” nitrogen

Answers

I believe it is B. If this is correct, please mark brainliest! :))

It necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass - d. because plants cannot use “free” nitrogen.

Nitrogen cycle is the series of processes where nitrogen converts into its compound move through the environment and in living organisms.

The processes here include fixation, ammonification, nitrification and denitrification.Majority of Earth's atmosphere is nitrogen.Nitrogen fixation is the process allows free nitrogen to available for plants.Plants can not use free nitrogen their for they require fixation and nitrogen fixating bacteria in nature.nitrogen fertilizers provide nitrogen for plants in soil therefore it necessary to add a nitrogen-based fertilizer to the soil.

Thus, It necessary to add a nitrogen-based fertilizer to the soil where there was a patch of grass - d. because plants cannot use “free” nitrogen.

Define homeostasis and explain why it is important.

Answers

Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside. All living organisms, from plants to puppies to people, must regulate their internal environment to process energy and ultimately survive.

Homeostasis is the ability of an organism or system to maintain a stable internal environment despite changes in the external environment. The term was coined by Walter Bradford Cannon in 1930 and comes from the Greek words "homeo," meaning "similar," and "stasis," meaning "standing still."

Homeostasis applies to the body's physiological processes, such as metabolism, temperature regulation, fluid balance, and hormone secretion. These processes involve a series of feedback mechanisms that sense changes in the body and trigger responses to restore balance. For example, when the body's temperature rises above a certain level, thermoreceptors in the skin and hypothalamus signal the sweat glands to produce sweat and the blood vessels to dilate, which helps to dissipate heat and bring down the temperature.

Homeostasis also applies to psychological processes, such as mood, stress, and arousal. These processes involve the brain's regulatory systems, such as the limbic system, the autonomic nervous system, and the endocrine system. These systems work in tandem to respond to internal and external stimuli, and regulate emotions, instinctual drives, and cognitive processes.

The concept of homeostasis is important in understanding health and disease. When homeostasis is disrupted, the body or mind may experience dysfunction, disease, or pathology. For example, chronic stress can lead to an overactive HPA axis and the release of cortisol, which can suppress the immune system and lead to inflammation and disease. Diabetes is also a condition where the body's homeostasis is disrupted, resulting in high blood glucose levels and impaired glucose metabolism.

Sonar sends a high frequency-sound to the bottom of the ocean. There, the sound waves bounce back when they hit an object. This “paints” a picture of what was hit. Sonar is used to see things at the bottom of the ocean.

The difference between PCR and real-time PCR is thatA. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.B. real-time PCR can amplify DNA a billion-fold within just a few hours, while standard PCR cannot.C. real-time PCR can determine the DNA sequence, while standard PCR cannot.D. real-time PCR uses DNA polymerase, while standard PCR does not.

Answers

Answer:

The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.

Explanation:

PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.
