Diatoms are the important marine autotrophs that have silica incorporated into their cell walls.

These microscopic algae are abundant in both freshwater and marine environments and are a major source of primary production in the oceans. Diatoms are critical to the marine food web as they are consumed by a variety of organisms, from zooplankton to larger marine animals. They are also important for their role in regulating the global carbon cycle, as they can sequester large amounts of carbon dioxide through photosynthesis.

In addition, the silica in their cell walls makes them a valuable resource for a variety of industrial and technological applications, such as water filtration and nanotechnology. Overall, diatoms are a vital component of marine ecosystems and play a crucial role in maintaining the health and productivity of the oceans.

Answer:

An actual computer virus is a malicious software, often known as malware, that can harm a computer and its users.

Virus hoaxes are false or misleading information about viruses that circulate through various communication channels.

They can be more dangerous than actual viruses due to their ability to spread quickly, cause panic, and undermine effective public health measures.

Virus hoaxes are deceptive messages or claims that often exaggerate the severity or impact of a particular virus. They can be spread through social media, email chains, or word of mouth. These hoaxes may include misinformation about symptoms, transmission methods, or false remedies, leading people to take ineffective or even harmful actions.

What makes virus hoaxes particularly dangerous is their potential to create panic and misinformation at a rapid pace. The viral nature of social media and other communication platforms allows these hoaxes to reach a wide audience within a short period. As a result, people may make decisions based on false information, such as avoiding necessary medical treatment, taking unnecessary precautions, or spreading fear and misinformation to others.

Moreover, virus hoaxes can undermine public health efforts by diverting attention and resources from legitimate preventive measures. They can erode trust in healthcare authorities and disrupt the dissemination of accurate information, making it harder for individuals to make informed decisions and follow recommended guidelines.

This can have severe consequences, especially during outbreaks or pandemics, where timely and accurate information is crucial for public safety. Therefore, it is essential to verify the credibility of information and rely on trusted sources to mitigate the risks associated with virus hoaxes.

Explanation:

In contrast to prokaryotes, eukaryotic cells feature internal membranes that enclose numerous organelles in addition to a plasma membrane that covers the entire cell.

Each membrane has its own set of specific proteins. within a lipid bilayer. The main distinction between prokaryotic and eukaryotic cells is that only eukaryotic cells have a nucleus and other membrane-bound organelles. Prokaryotes and eukaryotes are made up, respectively, of prokaryotic and eukaryotic cells. Prokaryotic cells typically lack the size and complexity of eukaryotic cells. In order to carry out metabolism, generate energy, and move chemicals throughout the cell, they need a number of specialised internal membrane-bound organelles.

DNA Replication is said to be semiconservative because when replication takes place, one of the original strands of DNA is conserved in every replica.

When DNA replication takes place, the double helix structure of the DNA molecule is broken. It is separated into two single DNA strands, each of these is then duplicated to create two new double helix strands, thus preserving one strand from the parent sample in each replication.

Therefore, due to the fact that each duplicated strand of DNA retains one of the original parent strands, it is said that the process is semiconservative.

A substrate interacts with an enzyme to generate an enzyme-substrate conformational change that resembles a key capable of matching to a particular lock in a door.

Enzyme specificity refers to the ability of an e3znyme to bind to a particular substrate in order to catalyze a chemical reaction. This binding lead to the formation of the enzyme-substrate complex where the substrate matches with the enzyme at the active site in a similar way to a lock and a key.

Therefore, with this data, we can see that enzyme and substrate are very specific and they interact in a similar way to a key and a lock in the door.

The larger the coefficient of selection, the faster allele frequencies will change via natural selection. The statement is True.

The coefficient of selection (s) represents the strength of selection acting on a particular allele. It indicates the reduction in relative fitness of individuals carrying that allele compared to individuals without the allele. When the coefficient of selection is larger, it indicates stronger selection against the allele.

In natural selection, alleles that confer higher fitness are more likely to increase in frequency over time, while alleles with lower fitness are more likely to decrease in frequency or be eliminated from the population. The larger the coefficient of selection, the greater the difference in fitness between individuals with the allele and those without it, leading to a stronger selective pressure.

Therefore, a larger coefficient of selection accelerates the rate at which allele frequencies change through natural selection, making it more likely for the allele to either increase or decrease in frequency in the population over generations.

3. D) 135 Kcal

4. C) Kudzu, a plant from Japan...

5. A) 15%

^This is confirmed valid as of January 17th, 2022^

Consumers are the organisms that depend on others for food and energy for the metabolic process while the producers produce their food at the trophic levels.

The correct options are 1. C, 2. A, 3. A, 4. A and 5. A.

1. In the trophic levels the energy gets decreased as it passes from one level to another because it is used in the cellular process it is released in the form of heat.

2. Secondary and tertiary consumers have to feed a lot and hence, they are fewer in number compared to the producers. They maintain the population and balance out the producer and consumer ratio.

3. According to the 10 % rule of energy transfer, the Tuna will receive 135 Kcal of energy because the energy decrease by 10% as one moves from the lower trophic to the upper levels.

4. The species that are non-native to a place or region are called invasive species hence, the Kudzu plant is the invasive species as it is introduced from Japan.

5. Given,

Energy of Seal = 2,500 Kcal

The energy of polar bear = 375 Kcal

Nonpolar tails on the inside of the membrane repel water. Option D

The basic structure of membranes is a phospholipid bilayer, which forms a stable barrier between two aqueous compartments. For the plasma membrane, these compartments are inside and outside the cell. When the cell membrane is formed, phospholipids assemble into two layers due to their hydrophilic and hydrophobic properties.

The phosphate head of each layer faces an aqueous or aqueous environment on either side, and the tail is hydrophobic and therefore hidden from water between the head layers. The most common membrane lipids are phospholipids. They have a polar head group and two hydrophobic hydrocarbon tails. The tail is usually fatty and varies in length usually containing 14-24 carbon atoms. The hydrophilic heads of the phospholipids within the membrane bilayer face outward and are in contact with aqueous fluids both inside and outside the cell.
