Answer:
a and b
Explanation:
The true statements regarding the mechanisms of antimicrobial action are:
Antisense nucleic acids interfere with protein synthesis.Beta-lactam antibiotics have an effect on bacterial and fungal cells because they both have cell walls.Nucleic acid analog drugs have no effect on human cell replication function.Options (2) (3) (4) are correct.
Antisense nucleic acids: Antisense nucleic acids are synthetic molecules designed to bind to specific mRNA sequences, preventing protein synthesis. This interference with protein synthesis can inhibit the growth and replication of pathogens.
Beta-lactam antibiotics: Beta-lactam antibiotics, such as penicillin, target bacterial cell walls by inhibiting enzymes involved in their synthesis. Bacterial cells and fungal cells both possess cell walls, making them susceptible to the action of beta-lactam antibiotics.
Nucleic acid analog drugs: Nucleic acid analog drugs, such as antiviral medications, are designed to mimic the structure of nucleic acids and interfere with viral replication. These drugs specifically target viral enzymes and processes involved in viral nucleic acid replication, without affecting human cell replication.

Explanation:
i got it right on the test
The common ancestor of these three organisms did not have lungs. So, the correct option is (B).
What is Lungs?Lungs are described as a pair of organs present in the chest that supplies oxygen to the body, and removes carbon dioxide from the body.
The lungs and respiratory system allow us to breathe which brings oxygen into our body which is known as inspiration or inhalation and removes carbon dioxide which is known as expiration or exhalation. This exchange of oxygen and carbon dioxide is called respiration.
The lungs are divided into segments or lobes with the right lung having three lobes while the slightly larger left lung has two lobes. These are separated by the mediastinum which contains the heart, trachea, esophagus and many lymph nodes.
Thus, the common ancestor of these three organisms did not have lungs. So, the correct option is (B).

What is stated in the central dogma
Answer:
The central dogma of molecular biology (sometimes Crick's central dogma after Francis Crick who coined the term and discovered some of the principles) states that the flow of genetic information is "DNA to RNA to protein". With a few notable exceptions, all biological cells conform to this rule.
(courtesy groups.inf.ed.ac.uk, article Central dogma of molecular biology)
Final answer:
The central dogma of molecular biology states that genetic information flows from DNA to mRNA to protein through the processes of transcription and translation.
Explanation:
The Central Dogma of Molecular Biology
The central dogma of molecular biology states that genetic information flows from DNA to mRNA to protein.
Transcription: DNA to mRNA
In the process of transcription, the DNA sequence is copied to produce a complementary mRNA sequence.
Translation: mRNA to Protein
In the process of translation, the mRNA sequence is decoded by ribosomes to produce a specific sequence of amino acids, forming a protein.
Exceptions to the central dogma can occur in connection with viral infections.

In 3–5 sentences, identify and analyze why investigations of past atmosphere composition and past climates could affect the use of fossil fuels today.
Answer:
Kindly see Explanation
Explanation: Fossil fuel may be identified as fuel formed over time as a result of prolonged burial or diagenesis of organic materials formed from decayed plants and animal remains. Given higher emmision level of Co2 usually produced from the burning of Fossil fuel such as coal, Crude oil and heavy oil due to increased energy consumption and the need to mitigate the adverse effect of global warming. Therefore, the need for more cleaner energy sources becomes imperative such as solar, wind, geothermal and other ver low emmision energy sources.
How does work transfer energy?
Answer:
Work is the transfer of energy.If you put energy into an object, then you do work on that object (mass). If a first object is the agent that gives energy to a second object, then the first object does work on the second object. The energy goes from the first object into the second object.
Explanation:
Energy is transferred as work when a force causes an object to move, with work measured in joules (force times distance). This energy can remain within the system, be stored for later use, or be dissipated, typically as heat due to friction.
Explanation:Work transfers energy when a force applied to an object moves the object over a distance. In physics, the concept of work is very specific: a force must cause displacement for work to have been done, and consequently for energy to be transferred. This transfer of energy can take various forms depending on the system and the type of work being done. For example, pushing a lawn mower involves transferring energy into the system, which is then dissipated as heat due to friction. On the other hand, when carrying a briefcase up stairs, work is done on the system, storing energy that can be retrieved later. This stored energy, representing work done on objects like the stones of the pyramids, can do work at a later time.
The scientific definition of work is not based on the effort exerted, but rather on the product of force and displacement. In terms of units, work and energy are both measured in newton-meters, where one newton-meter is equivalent to one joule (J). The joule is the standard unit of energy in the International System of Units (SI), quantifying the amount of work done when a one-newton force is applied over a one-meter distance.

To show gas exchange in the gills of a fish, why is it useful to include the mouth of the fish as well?
To explain gas exchange in fish gills, including the mouth is useful because it initiates the process of drawing water into the fish's body, leading to efficient gas exchange in the gills, with the help of the operculum.
Explanation:To demonstrate the process of gas exchange in the gills of a fish, it is beneficial to include an illustration of the mouth because the mouth plays a critical role in drawing water into the fish's body. The process begins with the fish opening its mouth to allow water to flow in and then pass over the gill filaments, which are the sites of gas exchange. This movement of water is essential to enabling the dissolved oxygen in the water to diffuse into the blood while carbon dioxide diffuses out. Including the mouth in the depiction of gas exchange in a fish helps students understand the complete process of respiration from start to finish, emphasizing the full path water takes when oxygen is extracted for the fish's metabolic needs.
The gills of bony fish are located in chambers that are covered and ventilated by the operculum, a protective flap that also plays a role in the process of respiration. Therefore, to understand the full mechanism of breathing in fish, it is helpful to show the interconnected action of the mouth and operculum, illustrating how water is continuously drawn over the gills for effective gas exchange.

Explanation:
Is it possible to have lightning without thunder? Is it possible to have
thunder without lightning? Explain.
HELP ASAP!!!
Answer:
1) Yes it is possible to have lightning without thunder, as you might see lightning but not hear the thunder as it was too far away. It's called "heat lightning" because it occurs in summer.
2) however it is not possible to have thunder without lightning as thunder is direct result of lightning.
Lightning cannot occur without thunder, as thunder is a result of the rapid expansion of air due to the heat produced by lightning. Thunder without lightning is not naturally possible. To calculate storm distance, the speed of light and sound are important.
Lightning and thunder are inherently connected phenomena with one typically not occurring without the other. Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves.
This discharge is a massive release of electricity that heats the air rapidly, causing it to expand explosively, which results in thunder. Due to this process, it is not possible to have lightning without thunder. The rapid expansion and contraction of air creates the sound waves that we hear as thunder.
On the other hand, thunder without lightning is not a natural occurrence, since thunder is directly caused by the heating and expansion of air due to the energy from a lightning bolt. There are instances, however, when lightning might strike far enough away that the thunder is too faint to hear, or the sound may be obstructed or refracted by the terrain. This could give the impression of lightning with no thunder, colloquially referred to as 'heat lightning'.
When calculating the distance of a storm, both the speed of light and the speed of sound are essential. Light travels much faster than sound, so you will see the lightning almost immediately. By counting the time until you hear the thunder and knowing the speed of sound, you can estimate how far away the storm is. Multiply the number of seconds by the speed of sound in air (approximately 343 meters per second), to get the distance in meters.
one role of enzymes in the human body.
Answer:
speed up the rate of virtually all of the chemical reactions that take place within cells.
Enzymes play a crucial role in the human body as biological catalysts that speed up chemical reactions necessary for various physiological processes.
Enzymes facilitate the conversion of substrates into products by lowering the activation energy required for a reaction to occur. Enzymes are involved in digestion, where they break down complex molecules such as carbohydrates, proteins, and fats into smaller components for absorption. They also participate in metabolism, helping to transform and utilize nutrients, regulate cellular processes, and generate energy.
Therefore, enzymes are vital in DNA replication, protein synthesis, and cell signaling, enabling efficient and precise biochemical reactions that are essential for the proper functioning of cells, tissues, and organs.
