Answers
Answer:
Antibiotics target the cell wall, cell membrane, and the processes of protein and nucleic acids production in bacteria to rupture the cell..
Explanation:
Final answer:
Antibiotics target bacterial structures and macro-molecules, inhibiting cell wall synthesis, damaging cytoplasmic membranes, disrupting DNA synthesis, and causing oxidative damage, which lead to bacterial cell death. These actions are integral to combatting bacterial infections without harming human cells.
Explanation:
How Antibiotics Affect Bacterial Structures and Functions
Antibiotics are potent medicines designed to combat bacterial infections by targeting specific bacterial structures and macro-molecules. These targeted attacks can lead to the disruption of essential cellular functions, ultimately causing the bacteria to die. Here are four different ways antibiotics or disinfectants may affect bacterial cells:
Inhibition of Cell Wall Synthesis: Many antibiotics, like penicillin, target the bacterial cell wall, which is essential for maintaining the cell's shape and integrity. By inhibiting the synthesis of the cell wall, the antibiotics cause the bacteria to burst and die due to osmotic pressure.Alteration of the Cytoplasmic Membrane: Certain antibiotics affect the cytoplasmic membrane's integrity, leading to leakage of cellular contents and resulting in cell death.Inhibition of DNA Synthesis: Some antibiotics, like fluoroquinolones, target enzymes involved in DNA replication. By blocking DNA synthesis, these drugs prevent the bacteria from replicating and carrying out necessary genetic functions.Oxidative Damage: Recent research suggests that all antibiotics might induce oxidative damage as a common effect. This damage, when severe enough, leads to cell death. Enhancing this effect by blocking bacterial defense mechanisms against oxidative damage can significantly increase the efficacy of antibiotics.Understanding these mechanisms is crucial, particularly given the rise of antibiotic resistance. Designing new strategies that leverage our knowledge about bacterial cell function and antibiotic action is important for developing more effective treatments against resilient bacterial strains.

which organism releases oxygen into the atmosphere
Answers
The organisms that are able to perform photosynthesis that include plants, algae and cyanobacteria release oxygen in the atmosphere.
What is photosynthesis?Photosynthesis is a process that uses light energy from the sun to convert carbon dioxide and water to oxygen and glucose. The reaction is given as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
That is, CO₂ is taken up from the atmosphere and O₂ that is formed is released back into the atmosphere.
Photosynthesis is a multistep process and occurs in two phases - light-dependent reactions and Calvin cycle.
The main purpose is obtaining energy in the form of sugar. Glucose that is formed is further catabolized to give ATP, which is the main source of energy.
It occurs in the chloroplasts. The light-dependent reactions occurs in the thylakoid membrane and the Calvin cycle occurs in the stroma.
It is because of photosynthesis that plants, algae and cyanobacteria are said to be autotrophic, that is capable of producing its own food.

C. the resulting compound is a good conductor or electricity
D. the resulting compound cannot be dissolved in water.
- Its A! they have high melting/boiling points.
Answers
Metallic bonds do have shiny surfaces (hence, the name metallic).
Metallic bonds are good conductors of electricity.
Metallic bonds cannot be dissolved in water.
The correct answer is option A.
-the resulting compound has low melting and boiling points
Answer:
The resulting compound has low and melting and boiling points.
Explanation:
Metallic bond: It is the type of bond (chemical) that hold the atoms of metal together, it forms when the electrostatic attractive force present between conduction electron and fixed positive charge metal atoms. So, metal atoms have high melting and boiling point. This means that they take lot of energy to overcome these Forces (electrostatic) during melting and boiling time.
It also describes as the sharing of free electrons between the structure of positively charged ions.

Answer:
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
Explanation: Hope this helps!!
A well-supported explanation of a feature of the natural world is called a scientific theory. It is based on a collection of facts that have been repeatedly verified via observation and experiment.
Such ideas are not "guesses," but rather trustworthy descriptions of reality. More than "simply a theory," biological evolution is a reality. It is just as factually accurate as the atomic theory of matter or the germ theory of disease in explaining the cosmos.
We're still working to fully comprehend gravity. Yet, just like evolution, the gravity phenomenon is a well-established fact.
Here are some of the key features of a scientific theory:
It is based on a body of evidence.
It is testable.
It is predictive.
It is widely accepted by the scientific community.
A hypothesis is not the same thing as a scientific theory. A hypothesis is a theory put up to explain a phenomenon. A well-researched and well-backed hypothesis is a theory.
Here are some examples of scientific theories:
The theory of gravity.
The theory of evolution.
The theory of relativity.
The scientific community generally accepts all of these hypotheses because they are testable, falsifiable, and predictive, and they are founded on a body of data.
Although scientific theories are not facts, they offer the most comprehensive account of the natural world that we know. While they are continuously tested and improved, they have withstood the test of time.

For your first paragraph: While James Watson and Francis Crick are credited with discovering the structure of DNA, they would not have been able to do it on their own. Without photo 51, taken by Rosalind Franklin using X-ray chromatography, they would not have known that the shape was a double helix. Chargaff discovered that in DNA the number of guanine units is equal to the number of cytosine units, and the number of adenine units is equal to the number of thymine units.

What causes the oceans to bulge near the equator compared to seawater at the poles?
A. Thermohaline circulation
B. The Coriolis effect
C. Centrifugal force
D. Convection
Answers
Answer:The answer is C. Centrifugal force
Explanation:
Answer:
The Centrifugal force makes the seawater to bulge at the equator when compared to the seawater at the poles.
Explanation:
The centrifugal force drives the earth rotation due to the bulging known as the equatorial bulging. But it is a different effect from tidal bulging.
Relatively the tidal effects are caused by the gravitational gradients that mean the differences in the gravity from one point to another point in the earth.
So centrifugal force is the reason for the bulge of seawater at the equator.
