Amino acids are the building blocks of proteins. They are organic compounds made up of an amino group (-NH2), a carboxyl group (-COOH), and a side chain that is specific to each amino acid. There are 20 different amino acids that are commonly found in proteins, each with a different side chain that gives it unique properties.

Explanation:

20 ATP is the predicted energy yield from the Krebs cycle per molecule of glucose in eukaryotic cells.

In general oxidation of one molecule of NADH leads to the synthesis of three molecules of ATP whereas oxidation FADH2 yield only two ATP molecule .

ATP synthase is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows the transfer of protons through the membrane using the kinetic energy to phosphorylate ADP making ATP.  ATP synthesis by chemiosmosis occurs in chloroplasts and mitochondria as well as in some bacteria.

Typically, homemade explosives are produced from products that are legally accessible in retail establishments across the country. The correct option is C

Homemade explosives are explosives that are produced using readily available materials and ingredients by individuals or groups outside of the commercial or industrial context.

Therefore, homemade explosives are produced from products that are (C) legally accessible in retail establishments across the country. This is because many of the ingredients commonly used in homemade explosives, such as fertilizer, fuel, and chemicals, are widely available for purchase without any special permits or identification requirements.

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

The flexibility of spider silk determined by the structure of its molecules is quite strong.

The components that make up spider silk are what give it its flexibility. Proteins called fibroins, which are made up of amino acids organised in a certain sequence, make up spider silk. The arrangement of amino acids in fibroin proteins results in a helical structure, which is held together by hydrogen bonds between the amino acids.

The fibroin protein chain's exact arrangement of amino acids and hydrogen bonds produces a special blend of strength and flexibility. The silk is flexible enough to stretch and absorb energy without breaking and robust enough to resist significant stress. Spider silk is a fantastic material for many uses, including clothes, medical equipment, and even bulletproof vests, thanks to its unique mix of qualities.

Explanation:

Genes A and B are dominant over O

Answer:

A person with type O could't have a baby AB

Explanation:

O with O = child can only be of type O. It will never be A, B, or AB.

O with A = child can be of types O and A. It will never be B or AB.

O with AB = child can be A or B. It will never be O or AB.

O with B = child can be of type O and B. It will never be A or AB.

The new Velocity_max is 0.5 mM per minute, which corresponds to option A.

To calculate the new Vmax, we can use the Michaelis-Menten equation, which relates the reaction rate (Vo) to the substrate concentration ([S]) and the maximum reaction rate (Vmax). The equation is given as:

Vo = (Vmax × [S]) / (Km + [S])

We have two sets of data points:

[S] = 5.0 mM, Vo = 0.25 mM/min

[S] = 2.0 mM, Vo = 0.333333333333 mM/min (approximately 1/3 mM/min)

From the first set of data, we can calculate the Km value by rearranging the Michaelis-Menten equation as:

Km = ([S] × Vmax) / (Vo - Vmax)

Substituting the values, we get:

Km = (5.0 mM × Vmax) / (0.25 mM/min - Vmax)

Similarly, from the second set of data, we get:

Km = (2.0 mM × Vmax) / (0.333333333333 mM/min - Vmax)

Since Km should be constant, we can set the two equations equal to each other:

(5.0 mM × Vmax) / (0.25 mM/min - Vmax) = (2.0 mM × Vmax) / (0.333333333333 mM/min - Vmax)

By solving this equation, we find Vmax = 0.5 mM/min.

Therefore, the new Vmax is 0.5 mM per minute, which corresponds to option A.

"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Explanation:

A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.

While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.

The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.

In a locked closet, there wouldn't be a lot of external effects and with ventilation, the chemicals would maintain their structure. In a pool closet, obviously, there would be a lot of moisture, so this could cause some explosive reactions to some of the chemicals. The sink in the kitchen has the same properties as in a pool closet. Finally on the ground in the garage wouldn't be a good place to store chemicals as it is cold and has little to no ventilation.

Both dichotomous keys and genetics (DNA) can be used as tools to classify organisms, but the accuracy of classification depends on the context in which they are used.

Dichotomous keys are useful for identifying and classifying organisms based on observable physical characteristics, such as their shape, color, size, and other morphological features. These keys work by providing a series of paired statements that help the user narrow down the possible identification of an organism until a final identification is reached. Dichotomous keys are particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics.

On the other hand, genetics (DNA) is a more accurate way to classify organisms at the molecular level. DNA analysis allows scientists to compare the genetic information of different organisms and identify similarities and differences in their DNA sequences. By comparing the DNA sequences of different organisms, scientists can determine their evolutionary relationships and classify them into different groups. DNA analysis is particularly useful for identifying and classifying organisms that are difficult to differentiate based on external characteristics or for organisms that have evolved to look similar to each other.

In summary, both dichotomous keys and genetics (DNA) are useful tools for classifying organisms, but DNA analysis is generally considered to be a more accurate way to classify organisms as it provides a more detailed and precise understanding of their evolutionary relationships.
