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.

You fill a storage cabinet with 12 bottles of normal saline. Each bottle contains 1000 mL. How many ounces of this solution are in the storage cabinet?
Answer:
Answer:amount of solution in the storage cabinet(ounces) ≈ 405.80
Explanation:
You are so h
There were 12 bottles of regular saline in the storage cabinet. Each bottle holds 1000 mL of ordinary saline, so 405.80 ounces of solution are contained in the storage cabinet.
How to calculate the ounces of this normal saline?This suggests that the storage cabinet's normal saline supply is 1000 mL divided by 12 bottles or 12000 mL.
Find the solution's volume in ounces in the storage cabinet, according to the query. As a result, we must convert from milliliters to ounces.
1 mL equals 0.033814022558919 ounces.
12000 = ?
The cross-multiplies
There are 12,000 ounces of solution in the storage cabinet, divided by 0.033814022558919.
405.768270707 ounces of solution are in the storage cabinet.
Therefore, 405.80 ounces of solution are contained in the storage cabinet.

Explanation:
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.

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.

What is the advantage to a scientist in using a line drawing rather than a ball-and-stick model or Lewis structure?
Answer:
It saves time
Explanation:
You don't have to draw unnecessary details for complex structures
Line drawings will save the scientist time instead of Lewis structure.
what is Lewis structure ?It is a representation of a molecule structurally, where dots are used to show the position of electron around the atoms and lines represent covalent bonds between atoms.
Lewis structure is used to identify the lone pair of electron in molecules which help to determine chemical bond formation.
Lewis structures is used for the molecule having covalent bonds and for coordination compounds.
It can be also known as Lewis dot diagrams, electron dot diagrams, Lewis dot formulas etc.
This structure are based on the octet rule and describe chemical bonding, do not describe aromaticity, magnetic behavior accurately.

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.

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.
