(Choice B) Lipids only
(Choice C) Lipids, proteins, and carbohydrates
(Choice D) Carbohydrates and lipids only
Answers
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.

What is the advantage to a scientist in using a line drawing rather than a ball-and-stick model or Lewis structure?
Answers
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.

What are the features of an energy-requiring reaction? Select all that apply. Small molecules are converted into complex organic compounds. The reaction requires an input of energy. The reaction results in the output of energy. Complex organic compounds are broken down into small molecules.
Answers
Answer:
-Small molecules are converted into complex organic compounds.
-The reaction requires an input of energy
Explanation:
Reactions in nature can either be energy-requiring or energy-releasing. Reactions that require energy are called ENDERGONIC reactions i.e. energy is needed to start the reaction provees. They are characterized by the INPUT OF ENERGY.
Also, when small molecules are converted into complex organic compounds by combining together in a process called ANABOLISM, energy is needed to put together the molecules to form a much larger complex molecules. Hence, it is a feature of energy-requiring reactions.
The features of an energy-requiring reaction include 'small molecules are converted into complex organic compounds' and 'the reaction requires an input of energy'.
An energy-requiring reaction is a type of reaction that requires energy, usually in the form of Adenosine Triphosphate (ATP), the energy coin of the cell.Anabolic reactions are chemical reactions that require energy to synthesize complex organic molecules from simpler ones.Conversely, catabolic reactions are chemical reactions that release energy by breaking down large organic molecules into smaller molecules.In conclusion, the features of an energy-requiring reaction include 'small molecules are converted into complex organic compounds' and 'the reaction requires an input of energy'.

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.
Answers
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.

Answers
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.

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
Answers
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.

Answer:
Species that are sympatric species can occur in the same location and are phenotypically different.
Explanation:
Speciation is the evolutionary process by which a population of a species acquires differentiating characteristics that lead it to distinguish itself from the species it formed. Sympatric speciation is a type of speciation that consists of the genetic separation of different populations of the same species that live in the same environment (same geographical location), so that species originate by divergence between individuals, that is, they diversify due to to the appearance of isolation mechanisms these can be genetic, ethological or sexual.
