Lightning is one of the natural mechanisms by which atmospheric nitrogen is converted to ammonia or ammonium ions.
Group of answer choices
A)False
B)True
The statement "Lightning is one of the natural mechanisms by which atmospheric nitrogen is converted to ammonia or ammonium ions" is definitely true. Thus, the correct option is B.
What is Lightning?Lightning may be defined as the occurrence of a natural electrical discharge of a very short duration. The discharge of atmospheric electricity produces the flashing of light.
Lightning is one of the natural mechanisms that initiate the process of nitrogen fixation. Through this process, the atmospheric nitrogen (N2) is converted to ammonia (NH3) or ammonium ions (NH4+).
Therefore, it is well described above.

Decide which two organisms to compare in your paper. Choose one organism that lives in the
tundra and another from a
desert region so that you are working with two contrasting environments. Read about the two habitats, and describe their
characteristics. Here are a few characteristics to consider:
• average temperature
• seasonal changes
• average rainfall or snowfall
vegetation
• land features
Answer:
Temperatures in a desert climate range from 86 to 104 degrees Fahrenheit, while summers are wet and winters are dry. When the rains fall, herds of prey animals abound as they feed on the lush grasslands and water at the many waterholes and rivers. The average rainfall in the desert is 10 inches per year. Sahara desert vegetation includes African Welwitchsia, date palm, thyme, magaria, olive trees, orange trees, and fig trees. Apart from these, more than half of the Sahara desert is extremely barren with no vegetation found. However, there are still some areas in the Sahara desert that are lush, containing abundant trees and plants. The most common landscape features found in deserts are sand dunes, yardangs, desert pavements, debris, playas, oases, mesas, alluvial fans, arroyos and buttes. These landforms vary from desert to desert. In areas dominated by the tundra climate type, winters are long and cold, especially in the region north of the Artic Circle where, for at least one day in the year, the Sun does not rise. Winter precipitation generally consists of dry snow, with seasonal totals less than in the summer when cyclonic storms that develop along the boundary between the open ocean and sea ice yield rainfall. The average snowfall in the tundra is 10-40 inches per year. Tundra vegetation is composed of dwarf shrubs, sedges and grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone between the tundra and the forest is known as the tree line or timberline. The arctic tundras located between the north pole and the coniferous forests or taigaregion. It is characterized by extremely cold temperatures and land that remains frozen year-round. Arctic tundra occurs in frigid mountaintop regions at very high elevations.

You want to test which size of soccer (football) ball is easiest to juggle with your feet. You test a size 3, size 4 and a size 5 ball. You count the seconds the ball stays in the air for each of the trials. You allow yourself to use both of your feet, knees, and head to juggle the ball. a. Independent Variable: b. Dependent Variable: c. Control Variable:
Answer:
independent variable: size of soccer ball
dependent variable: period of time the balls stay in the air
control variable: parts of the body used to juggle the ball
Explanation:
The independent variable is the manipulatable variable supplied into an experiment. It is a variable that directly affects the dependent variable.
The independent variable is the outcome variable. It is the variable that is primarily measured from experiments whose value depends on the value of the independent variable.
The control variables are those that are kept constant throughout the course of experiments. In other words, they do not directly affect experimental outcomes.
Hence, in the illustration;
independent variable: size of soccer ball
dependent variable: period of time the balls stay in the air
control variable: parts of the body used to juggle the ball
Which of the following is an example of postzygotic isolation?
A. Allopatric Speciation.
B. Gamete incompatibility.
C. Hybrid sterility.
D. Polyploidy.
Answer:
C
Explanation:
The correct answer here would be hybrid sterility.
Postzygotic isolation refers to the mechanisms of reproductive isolation that occur after two organisms of different species have successfully mated and fertilization/formation of zygote has occurred.
Generally, reproductive isolation mechanisms act to prevent members of different species from mating (pre-zygotic)or prevent their products of mating from being viable (postzygotic). A hybrid is a product from mating of two different species of organisms.
The mechanisms of postzygotic isolation include the production of hybrid zygotes that are not viable and hence, will not make it past the embryonic stage or if they do, the resulting offspring remains sterile.
Hence, hybrid sterility is an example of a postzygotic isolation mechanism.
Julie has been working in the laboratory with a new antibiotic. First, she placed an
antibiotic on a petri dish of bacteria. Then she placed a solution of distilled (plain)
water in the petri dish and observed under the microscope that water moves into the
bacterial cells, causing them to burst. In the control group of bacteria that did not
receive the antibiotic, the cells do not swell or burst. Julie is trying to determine what
organelle must be damaged by the antibiotic to allow for the cell to burst.
Answer:
contractile vacuole.
Explanation:
Contractile vacuole is an organelle which is damaged from the antibiotic and as a result the cell burst. The main function of contractile vacuole is to regulates the quantity of water inside the cell. If the contractile vacuole is damaged so it does not regulate water required by the cell as a result more water enters inside the cell which results in the bursting of the cell.

(Choice D) Carbohydrates and lipids only
Answer:
(Choice C) Lipids, proteins, and carbohydrates
Explanation:
The cell membrane is also known as the plasma membrane. The cell membrane made of lipids, proteins, and carbohydrates. Therefore, option C is correct.
What is cell membrane ?The cell membrane is also called as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane made up of lipids and proteins and carbohydrates.
The plasma membrane produce the boundary in between the outer environment and living systems.Mitochondria, chloroplast , and nucleus consist of two membranes that are one outer and one inner.
The cell membrane is present on the cell walls of the cells in animals. The cell membrane is located in between the cytoplasm and cell wall in plants. The cell membrane provide protection to the cell.
Thus, option C is correct.

A water molecule is polar because there is an uneven distribution of electrons between the oxygen and the hydrogen atoms. Therefore, the correct option is A.
A water molecule (H₂O) consists of two hydrogen atoms linked to one oxygen atom.
The electronegativity of oxygen is 3.44 which is higher than the electronegativity of hydrogen, which is 2.2. As a result, it tends to pull the shared electrons towards itself, because of which it acquires a partial negative charge and the hydrogen atoms acquire a partial positive charge.
As a result of unequal sharing of electrons, a dipole moment in the molecule is created, making the water molecule polar.

A weakened immune system may be caused by immunodeficiency disorders.
What is the Immune system?
The immune system means the protection of our body from different pathogens which are non-self agents. It is a complex network of cells, tissues, organs, and the substances they make that helps the body fight infections and other diseases.
Immunodeficiency disorders destructs the immune system's ability to defend the body against foreign molecules or abnormal cells that invade or attack it, such as bacteria, viruses, fungi, and cancer cells. As a result, unusual bacterial, viral, or fungal infections or lymphomas are caused and spoils the immune system completely.
Therefore, a weakened immune system may be caused by immunodeficiency disorders.
