(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down damaging toxins created by bacteria. b They increase the number of white blood cells in the blood. c They rupture the cell wall or prevent protein synthesis in bacteria. d They reduce the effects of fever, swelling, and inflammation in the body.

Answers

Answer:

The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.

Explanation:

Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.

The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:

Destruction of the bacterial wall or membrane. Interference with protein synthesis. Inhibition of the synthesis of nucleic acids.

In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.

The other options are not correct because:

    a. Breaking down damaging toxins created by bacteria is an anti-toxin function.

    b. Antibiotics do not increase the number of white blood cells in the blood.

    d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.

Answer:

They rupture the cell wall or prevent protein synthesis in bacteria.

Compare temperature and pressure conditions on the Earth's surface to those below the Earth's surface, and relate these conditions to the process of lithification.

Answers

Answer:

Explanation:

The temperature and pressure on the earth's surface is lower than that below the earth's surface. Generally, temperature and pressure increases as you move/dig down the earth's surface. This increase in temperature and pressure causes the earth's sediment (below the earth surface) to form a compact solid rock - this process is known as lithification.

How does osmosis of water occur across the cell membrane?Plz help I need it ASAP

Answers

Answer:

In osmosis, molecules cross the cell's plasma membrane to achieve equilibrium.

Explanation:

A bilipid layer called a plasma membrane typically surrounds cells. Here, lipid molecules are arranged tail-to-tail, with their heads facing outwards. The heads of the lipids, are water soluble, while the tails are insoluble. Proteins and cholesterol also help maintain membrane fluidity.

With the use of its transport proteins, pores and gated channels, embedded among the lipids the membrane maintains its concentration of substances through selective permeability.

Simple diffusion occurs in cells through plasma membranes as a means of passive transport. In osmosis, molecules of water move across the membrane, down their concentration gradient- i.e. they try to balance their concentration or number of water particles.

The water particles move from regions of high concentration to regions of low water concentration. Typically these 'destinations' or regions have large amounts of solute which contributes to the formation of this gradient.

What has no nucleus and a large surface area?

Answers

Answer:

prokaryotic cells

Explanation:

a  example of a prokaryotic cell would be a blood cell they have no nucleus and a large surface.

Answer:

The answer would be Prokaryotic Cells

Explanation:

  A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles. These Prokaryotic cells are not divided up on the inside by membrane walls, but consist instead of a single open space.

  The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome. So technically these cells lack nucleuses, while still containing genetic material(s).

Proteins are synthesized based on genetic information carried by DNA. Explain how the structure of DNA is important in the synthesis of different kinds of proteins. In your explanation, include a description of the two main processes involved in protein synthesis.

Answers

Answer:

One of the single most significant biological processes that individual cells are capable of would be building their specific proteins. This process is referred to as protein synthesis. DNA (deoxyribonucleic acid) and RNA (ribonucleic acids) are involved in protein synthesis, which occurs in the given cell's nucleus. The DNA has a unique structure vital for distinct enzymes to unwind in a specific section of DNA. This, in turn, makes that section accessible for an RNA copy to be made. Once made, the RNA molecule moves from the given cell's nucleus to its cytoplasm, where, finally, the actual protein synthesis process can occur.

Explanation:

took me awhile to research this

Proteins are synthesized by the DNA through the processes of the central dogma. Proteins are essential for cell growth, functioning, structural arrangement etc.

DNA is a double-stranded nucleic acid that contains genetic codes and information. DNA replicates to form two daughter cells by the process of replication.

The duplicated DNA serves as a template for the construction of RNA by the process of transcription. The unique double helix of deoxyribonucleic acid makes it accessible for the formation of mRNA.

The single-strand RNA have nucleotide bases that code for the amino acids with the help of tRNA and ribosomes by the process of translation.

The amino acids produced bonded together to create proteins.

4) The carbon dioxide comes from the animals and the oxygen comes from plants

7) Animals need to get their energy from other living things, but in order to do that said other living things need to have energy for the animals to get. Photosynthesis is the means by which plants and algae get their energy. Animals also need elemental oxygen,and photosynthesis produces this as a waste product as well

9) Fossil fuels consist mainly of carbon and hydrogen. When fossil fuels are combusted (burned), oxygen combines with carbon to form CO2 and with hydrogen to form water (H2O). These reactions release heat, which we use for energy

Reducing the frequency of lawn watering during rainy seasons will help

reduce groundwater overuse.

Groundwater is found deep below the soil as a result of them seeping into

the ground during rainfall. Some of them are emptied into water bodies such

as seas, oceans etc. Water pumping machines forces the water out for

Question 6(Multiple Choice Worth 5 points) (MC) New Technology Leads to Bigger Cities In the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas. Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall. The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas. As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization. In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents. The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas. Which sentence from the conclusion paragraph best rephrases the author's thesis? The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly.
