Explanation:

The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.

Many other mutations have no effect on the organism because they are repaired beforeprotein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA. One way DNA can be repaired is illustrated in Figure below. If a cell’s DNA is permanently damaged and cannot be repaired, the cell is likely to be prevented from dividing.

To convert grams of fat to kilocalories (kcal), we need to know the energy value of fat, which is approximately 9 kcal per gram.

In this case, you consumed 30 grams of fat. To calculate the kilocalories, we can multiply the grams of fat by the energy value:

30 g fat * 9 kcal/g = 270 kcal

Therefore, consuming a cup of ice cream containing 30 grams of fat would provide approximately 270 kilocalories. It's worth noting that this calculation assumes that all the fat consumed is metabolized and utilized for energy.

Keep in mind that this is a simplified estimation and does not take into account other factors such as individual metabolism and specific ice cream composition.

The correct flow of air leaving the bronchial tree from the alveoli is respiratory bronchioles, terminal bronchioles, bronchioles, tertiary bronchi.

The respiratory bronchioles are the smallest airways of the bronchial tree that have alveoli buds on their walls. They branch from the terminal bronchioles, which are the last segment of the conducting zone of the respiratory system.

The bronchioles follow the respiratory bronchioles and they are small airways that lack cartilage in their walls, making them more susceptible to collapse.

Finally, the tertiary bronchi, also known as segmental bronchi, are the first branches of the bronchial tree that lead to specific lobes or segments of the lung.

So, the flow of air leaving the bronchial tree from the alveoli starts from the respiratory bronchioles, followed by the terminal bronchioles, then the bronchioles and finally the tertiary bronchi.

One impact of pollution of mercury is the potential harm it can cause to human health, particularly to children exposed to mercury in fetal development.

Studies have shown that such exposure can lead to a loss of IQ. Additionally, mercury pollution in the ocean can harm marine wildlife, as it can coat the feathers of birds and animals, making it difficult for them to fly or swim. Long-term exposure to mercury can also lead to serious health problems in both humans and wildlife, including cancer, lung disease, kidney disease, and convulsions.

Therefore, it is important to reduce mercury pollution to protect both human health and the environment.

To determine the number of mice that will be infected next week and in three weeks, we need to consider the probabilities of mice overcoming the virus and becoming infected. So according to given information 240 mice are will be infected in next week and 224 mice are will be infected in 3 weeks.

Next Week:

Currently, 300 mice are infected. Since there is a 90% chance that an infected mouse will overcome the virus, we can calculate the number of infected mice that will remain next week as follows:

Remaining infected mice = 300 * (1 - 0.9) = 30 mice

At the same time, there is a 30% probability that a non-infected mouse will become infected. We have 700 non-infected mice, so the number of mice that will be newly infected next week is:

Newly infected mice = 700 * 0.3 = 210 mice

Therefore, the total number of infected mice next week will be:

Total infected mice = Remaining infected mice + Newly infected mice = 30 + 210 = 240 mice

In 3 Weeks:

To calculate the number of mice infected in three weeks, we can repeat the same process.

Remaining infected mice after one week = 240 * (1 - 0.9) = 24 mice

Newly infected mice in the second week = 676 * 0.3 = 202.8 ≈ 203 mice

Remaining infected mice after two weeks = 203 * (1 - 0.9) ≈ 20.3 ≈ 20 mice

Newly infected mice in the third week = 680 * 0.3 = 204 mice

Therefore, the total number of infected mice in three weeks will be:

Total infected mice = Remaining infected mice after two weeks + Newly infected mice in the third week = 20 + 204 = 224 mice.

Such organisms and the fossil fuels they produce are often millions of years old, and occasionally even older than 650 million years. Petroleum, coal, and natural gas are examples of fossil fuels that have high carbon content.

Kerosene and propane are examples of frequently employed fossil fuel derivatives. Under several thousand feet of silt, flammable geologic deposits of organic materials, such as dead plants and animals, are what are known as fossil fuels. Due to the intense heat and pressure within the earth's crust, these deposits began to deteriorate over time and were eventually transformed into natural gas, coal, and petroleum. Carbon dioxide is resealed in multiple amounts during the burning of fossil fuels, acting as a greenhouse gas.

The gases that absorb and release radiation are known as greenhouse gases, and they are what causes the greenhouse effect. The greenhouse gases are methane, water vapour, and carbon dioxide. Fuels known as fossil fuels are produced through the rotting of dead plant and animal carcasses.

These fuels are present in the Earth's crust and mostly consist of carbon and hydrogen. Coal, petroleum, and crude oil are a few examples of fossil fuels. To comprehend how these fossil fuels are generated, we can examine the complete coal formation process.

◯ The myosin and actin myofilaments of cardiac contractile cells are organized into sarcomeres.

Cardiac contractile cells are specialized muscle cells found in the heart. They are responsible for the forceful contraction of the heart, which allows it to pump blood throughout the body. One characteristic of cardiac contractile cells is that their myosin and actin myofilaments are organized into sarcomeres, which are the basic functional units of muscle contraction.

The other statements are false or contain inaccuracies:

- Cardiac contractile cells are not necessarily short and branched. While cardiac muscle cells can exhibit some branching, their size and shape can vary.

- The number of nuclei in cardiac contractile cells can vary, and it is not limited to one or two. Cardiac muscle cells can contain one or more nuclei, depending on their location and developmental stage.

La autocomplementariedad de cada cadena de ADN o ARN permite la formación de estructuras como hebras y cruciformes. Estos motivos estructurales son fundamentales en el plegamiento de ADN y ARN, la regulación génica y otros procesos biológicos.

La autocomplementarity de cada cadena de DNA o RNA permite la formación de varios motifs estructurales. Particularmente, esta autocomplementarity concede la capacidad de crear hebras y estructuras cruciformes. In the case of one hairpin, a single strand folds back on itself, creating a stem-loop structure. El patrón de enrollamiento más complejo es el resultado de dos estructuras de nudo que involucran dos regiones complementarias dentro del mismo rollo. Sin embargo, los palindromes muestran repeticiones invertidas dentro de una fibra, lo que permite la unión de pares de base y la formación de estructuras de forma cruciforme o B.

Every DNA strand has the ability to produce hairpin structures due to its self-complementarity. When a single strand curls back on itself, creating a stem-loop structure, the result is a hairpin structure.

Hydrogen bonds formed between complementary nucleotides in the same strand help to stabilise this structure.The term "cruciform" describes a DNA structure that takes on a cruciform shape when two hairpin structures inside the same DNA molecule align in an antiparallel direction. Palindromic sequences, which are DNA sequences that read the same on both strands when the directionality is ignored, are frequently linked to cruciform formations.The usual right-handed double helical DNA helix, which is most frequently seen under physiological settings, is referred to as being in "B-form" instead.

Answer:

has a particular shape that matches the substrate

Explanation:

Enzymes are proteinous biological catalyst i.e. they speed up the rate of biochemical reactions in living systems. Like every other catalyst, enzymes reduce the activation energy of the reactions they are involved in without getting used up in the process.

Enzymes operate by binding to a substrate molecule i.e. the reactant and form a bond with them in order to synthesize a product. However, enzymes are substrate-specific i.e. they are very particular about the substrate they bind to. This property is due to the shape of the enzyme which matches a particular substrate.

Enzymes, like every other protein molecules, are made up of amino acid subunits, which are responsible for the shape that determines the specificity of the protein.
