he conversion process where nitrogen gas combines with hydrogen to form ammonium ions, which is accomplished through the intense energy of lightening, or when air in the top layer of soil comes into contact with certain bacteria, is known as
Answers
Answer: The conversation process where nitrogen gas combines with hydrogen to form ammonium ions is known as THE ACTION OF THUNDERSTORMS while when air in the top layer of soil comes into contact with certain bacteria, nitrogen in the air is converted by NITROGEN- FIXING MICROORGANISMS.
Explanation:
About 79% of air is composed of gaseous nitrogen. However, only a few microorganism can make use of this nitrogen. The important sources of nitrogen for plants and most living organisms are the inorganic nitrogenous compounds in soil. In nature, nitrogen is constantly being removed from the soil and returned to it through the NITROGEN CYCLE
Conversation of gaseous Nitrogen into nitrogenous substances such as ammonium and amino-compouds are carried out by:
--> The action of thunderstorms, and
--> NITROGEN- fixing microorganisms.
During thunderstorms, Nitrogen reacts with oxygen to form nitric oxide. The nitric oxide is oxidizes to Nitrogen peroxide which dissolves in rainwater to form nitric and nitrous acid. When these acids enter the soil, they combine with mineral salts to form nitrates. The nitrates then, dissolve in soil water and are absorbed by the plants. These nitrates are converted into plant proteins and become part of the plant body.
Some microorganisms such as the Nitrogen fixing microorganisms are able to absorb nitrogen from the atmosphere and change it into amino-compouds and proteins. Examples of such microorganisms include:
--> the free living bacteria: these include the azotobacter and clostridium
--> the symbiotic bacteria: the rhizobium which is found in the root nodules of leguminous plants

A farmer decides to test whether or not a fertilizer will make her crops grow bigger. In year 1, she plants corn in two different fields on her property and fertilizes one and not the other. She measures the height of 10 corn plants in meters from each field. She takes her measurements every week for three months. In year 2, she puts irrigation in one of the fields and conducts the same experiment.
Required:
a. What is the independent variable and the treatments (increments) used in the experiment?
b. What is the dependent variable and the units in which it was measured?
c. Name at least two controlled variables:
d. What is the hypothesis?
e. Identify two sources of error in the first year in the experiment:
f. Identify two sources of error in the second year in the experiment:
Answers
Answer:
a. independent variable: the fertilizer.
treatments: the use of fertilizer in one of the fields.
b. dependent variable: the crop growth in height.
units: meters
c. two controlled variables: soil pH / solar-radiation exposure, and water supply
d. hypothesis: the fertilizer makes the crops grow bigger.
e. two sources of error in the first year:
the researcher might plant the two crops under different conditionstake wrong measures of the height of the cornsf. two sources of error in the second year:
she can fail in irrigating the crops climatic and environmental conditions might change and have different consequences on each of the fields (this source affects the results influencing the growth of the plants).Explanation:
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. These changes allow analyzing its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the fertilizer is the independent variable. Treatments: Refers to the experimental procedure applied in the experimental group. In this example, the use of fertilizer is the treatment. Here the experimental group (the one that receives the experimental procedure, with changes in the independent variable) is the fertilized field. Data from the experimental group is compared with the data from the control group, to analyze the effects of the fertilizer.Dependent variable: The values of these variables respond to any change in the independent variable. It represents the quantity of something. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the crop growth rate in height is the dependent variable, that depends on the fertilizer used in that field. The units in which the crop is measured are meters in height. Controlled variable: Refers to those variables equally applied to every group or subject in an experiment and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, soil pH and solar-radiation exposure can be two controlled variables, as they must be equal for both fields. Water supply by irrigation ducts during the second year in both fields is also a controlled variable. Hypothesis: A hypothesis is a possible answer for a question, a speculation that is not verified yet and requires corroboration. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. It must be objective and directly related to variables. In this example, the hypothesis might be that the fertilizer makes the crops grow bigger. Errors: These are the differences between the observed data or taken values and what is really happening in nature, which can lead to a misinterpretation of what is actually going on. These errors might be systematic mistakes performed by the researcher when measuring, taking data, applying the treatment, etc. Or they might be due to random errors, which are due to failures in the instrumentals, changes in the environment, a single mistake of the researcher while taking measures, among others. During the first year, the researcher might plant the two crops under different conditions (parcels with different slopes which affect solar-radiation) or might commit a mistake while applying the fertilizer (different concentrations for example), or might take wrong measures of the height of the corns. During the second year, she can fail in irrigating the crops correctly, providing more water to one of the fields. She can commit the same measuring mistakes. Or even climatic and environmental conditions might change and have different consequences on each of the fields.What impact do you hope to have on the world and how will STEM play a role in making that impact, Essay pls help need ASAPPPP WILL MARK BRAINLIEST

Two populations have been geographically isolated from each other for many generations.
Which statement is most likely correct about the two populations?
O They can still produce viable offspring with each other.
O They can't reproduce with each other.
O They look very similar to each other.
O Their gene pools are highly similar.
Answers
Answer:
The most likely correct statement about the two populations that have been geographically isolated from each other for many generations is "Their gene pools are highly dissimilar."
When populations are geographically isolated from each other, they are unable to interbreed, therefore, they evolve independently from each other. Over time, different selection pressures and mutations cause genetic differences to accumulate between the two populations. These genetic differences will become evident when the two populations are brought back together. If the genetic differences are large enough, the two populations may no longer be able to interbreed and produce viable offspring.

Pathogens are microorganisms, such as bacteria, viruses, fungi, and parasites, that cause diseases in humans, animals, and plants. They are capable of infecting the body and causing illness by invading host cells, tissues, and organs, and disrupting normal physiological processes.
They respond to pathogens in a non-specific way, meaning they do not target a specific pathogen but rather any foreign material that enters the body.
The immune system has two main components: non-specific immunity and specific immunity.

Part 2: David’s Physical Condition
At his trial, David’s defence argued that his behaviour had not
been under his control. Shortly before his behaviour changed,
David had accidentally been exposed to a high concentration
of an organophosphate pesticide called carbaryl. Carbaryl is a
substance that can have an effect on the nervous system. In
fact, it behaves similarly to many nerve gasses (chemical weap-
ons that exert their effect by impairing the functioning of the
nervous system).
Carbaryl works by affecting the way that brain cells communi-
cate with each other. This communication occurs at synapses,
little gaps at the junctions of nerve cells. Neurones (nerve cells)
release chemicals to send signals across the gap. These chem-
icals are called neurotransmitters. After it has been released,
the neurotransmitter is broken down to prevent it from stimu-
lating the post-synaptic neurone for any longer than necessary.
Carbaryl prevents the breakdown of a neurotransmitter called
acetylcholine (ACh). Exposure to high doses of carbaryl causes
ACh to build up in the brain and other parts of the nervous system.
One of the many parts of the brain that uses ACh is a structure called the hypothalamus. This structure is im-
portant in a huge range of behaviours including eating, drinking, sex, and aggression. Electrical stimulation of
specific parts of the hypothalamus can cause a rat to show signs of rage and attack behaviour. David’s defence argued that the carbaryl to which he had been exposed had
affected the functioning of his hypothalamus. A small provocation would have
started the parts of the hypothalamus associated with attack behaviours to
start firing. However, because of the carbaryl, they would not have been able to
stop, leading to uncontrolled rage and aggression.
Discussion Questions:
• Based on the evidence provided, do you think David is morally responsible
for his crime?
• What possible environmental influences may have incited David to act as he did?
• Why do you think the jury believed the prosecution in spite of the defence’s
argument?
• How does this case affect your views on the nature versus nurture debate?
Answers
Based on the evidence provided, the question of David's moral responsibility for his crime is complex. The defense argues that his behavior was not under his control due to the accidental exposure to carbaryl, which impairs the functioning of the nervous system.
Carbaryl prevents the breakdown of the neurotransmitter acetylcholine (ACh), leading to its buildup in the brain and other parts of the nervous system.
The defense further argues that this affected the hypothalamus, a brain structure involved in various behaviors, including aggression.
The environmental influence that may have incited David's behavior is the accidental exposure to a high concentration of carbaryl, an organophosphate pesticide.
The jury may have believed the prosecution despite the defense's argument due to several reasons.
Nature vs. Nurture Debate: This case raises questions regarding the nature versus nurture debate, which explores the relative contributions of genetic and environmental factors in shaping human behavior.

However, if we assume that you are sitting in a chair and ask how fast you are moving relative to the Sun, the answer would depend on the reference frame. From the perspective of someone standing on the Sun, the Earth (and therefore you and your chair) is moving in an elliptical orbit around the Sun at an average speed of about 30 kilometers per second (67,000 miles per hour). From the perspective of someone standing on the Earth, you and your chair are stationary (ignoring the rotation of the Earth) while the Earth is rotating on its axis and orbiting the Sun at the same speed mentioned above.
