As long as a protein contains the same amount of each specific amino acid, the order/sequence of these amino acids does not impact the protein's structure (and, therefore, function). The statement is false.
Does every protein have the same amino acid sequence?
Each protein has a distinct sequence of amino acids that is identical from one molecule to the next. There are thousands of different proteins, each with its unique amino acid sequence.
Since the chemical composition of each amino acid is influenced, which gives rise to intermolecular interactions that begin to create secondary structures such as -helices and -strands, the protein sequence of amino acids helps determine protein shape.
Therefore, the order/sequence of these amino acids does impact the structure (and therefore function) of the protein

The correct answer is option C i.e. incomplete dominance
when a true-breeding red flower is crossed with a white flower, and all the f1 flowers are pink, this is due to incomplete dominance.
In a cross between true-breeding red flower RR and white flower rr in F1 generation, we get pink colored flower Rr. This type of inheritance is called incomplete dominance as neither of them is completely dominant over each other.

Answer: I will just provide the answers together with the explanation.
Explanation:
1.a) Digestive enzymes breakdown large food molecules into smaller soluble forms.
b) Food needs to be absorbed into the blood in order for it to be carried into the cells through the blood and for this it needs to be soluble into the blood otherwise the cells will not get nutrition. Digestive enzymes breakdown the food into very small soluble form so that they are easily soluble in the blood
2.a) It accurately depicts the breakdown of a large object into smaller pieces
b) There are different enzymes for different substances. One enzyme cannot breakdown all substances like one scissor can cut different shapes.
Extra info: The substances broken down by enzymes are called substrates. If the shape of the substrate does not match with the active site (where the breakdown occurs) of the enzyme, the enzyme will not affect it at all.
3.a) The model clearly depicts that the enzymes need to match with the substrates like keys to a lock for it to affect the substrate. the mouth of the spanner is like the active site of the enzyme. It only works when the shape of the nuts matches with it.
b) It shows that the substance itself is not broken down but pieces of the substance is taken apart which enzymes do not do. Enzymes breaks down a substance completely into smaller parts.
Select the correct order of the final three stades in the lytic cycle
The correct order of the final three stages in the lytic cycle is Assembly > Transduction > Release
What is a Lytic cycle ?One of the two viral reproduction cycles, the other being the lysogenic cycle, is the lytic cycle. The infected cell and its membrane are destroyed as a result of the lytic cycle. Virulent phages are bacteriophages that only utilise the lytic cycle.
Although the lytic cycle's final result is the generation of new phage offspring and the death of the host bacterial cell, this is a multistep process that requires careful synchronisation of physical processes and gene transcription.The primary distinction between the lytic and lysogenic cycles is that the lytic cycle kills the host cell, but the lysogenic cycle does not. The host cell's DNA is destroyed by viral DNA, which also halts the cell's lytic cycle.Learn more about Lytic cycle here:

Describe how the light-dependent and light-independent reactions work together in photosynthesis
According to the research, in photosynthesis, through the light-dependent reactions energy is contained in the NADPH and ATP molecules that is used by light-independent reactions.
What is photosynthesis?It is the process that converts solar energy into chemical energy which, stored in cells, allows the formation of carbohydrates and other organic molecules.
In this sense, the light-dependent reactions occur in the thylakoids whose chemical energy is comprised of molecules of two types NADPH and ATP.
On the other hand, light-independent reactions occur in the chloroplast matrix with the intervention of enzymes that intervene in the reduction of CO2 molecules to establish carbohydrates through the energy sources ATP and NADPH.
Therefore, we can conclude that the light-dependent reactions in photosynthesis manufacture ATP and the reducing source NADPH necessary for light-independent reactions.

2. What is the importance of NAD+ cycling back up to glycolysis?
The cycling of NAD+ back up to glycolysis is crucial for sustaining energy production, maintaining redox balance, and allowing for the efficient functioning of cellular respiration.
The cycling of NAD+ back up to glycolysis is crucial for the efficient functioning of cellular respiration and energy production. Here are the key reasons for its importance:
NAD+ regeneration: During glycolysis, glucose is metabolized to produce energy in the form of ATP. As part of this process, NAD+ acts as an electron carrier, accepting electrons from glucose and becoming reduced to NADH. NADH carries these electrons to the electron transport chain for further ATP synthesis. However, NAD+ is required to sustain glycolysis. Without a mechanism to regenerate NAD+ from NADH, the glycolytic pathway would quickly halt due to a lack of available NAD+. Therefore, the cycling of NAD+ is crucial for maintaining a continuous supply of NAD+ for glycolysis.ATP production: The regeneration of NAD+ is directly linked to ATP production. NADH carries high-energy electrons to the electron transport chain, where they are used to generate ATP through oxidative phosphorylation. If NADH accumulates and NAD+ levels decrease, electron transport and ATP synthesis would be compromised, resulting in reduced energy production.Redox balance: The cycling of NAD+ is essential for maintaining redox balance within the cell. As NAD+ accepts electrons during glycolysis, it becomes reduced to NADH. Regenerating NAD+ from NADH helps balance the cellular redox state, ensuring that other redox reactions in the cell can proceed smoothly. Without NAD+ cycling, an imbalance in the redox state could lead to disruptions in various metabolic pathways and compromise cellular function.Learn more about Glycolysis, here:

Please show workings
A typical adult would have to drink 566.6 cm³ more milk to get their RDA for calcium compared with the amount of milk needed to get their RDA for vitamin B-12
What volume of milk is needed to meet the Recommended Daily Allowance for Calcium and Vitamin B-12?The volume of milk needed to meet the Recommended Daily Allowance for Calcium and Vitamin B-12 is calculated as follows:
RDA for calcium = 1000 mg
500 cm³ of milk contains 600 mg
Volume of milk required for RDA calcium = 1000 * 500 / 600
Volume of milk required for RDA calcium = 833.3 cm³
RDA for Vitamin B-12 = 2.4 µg
500 cm³ of milk contains 4.5 µg
Volume of milk required for RDA Vitamin B-12 = 2.4 * 500 / 4.5
Volume of milk required for RDA Vitamin B-12 = 266.7 cm³

Include how this might affect the use of the glaister equation in determining the time of death.
The ambient temperature affect the rate of cooling of a body after death occurs depends on the temperature differential between the body and the environment.
How long does it take for the body to cool down after death?Once vital functions cease, the body cools at an average of 1°C to 1.5°C per hour. Considering that the average temperature of a human being is between 36 °C and 37 °C, the corpse reaches the ambient temperature in 24 hours at most.
The higher the ambient temperature, the more important the evaporative heat loss will be. In fact, when ambient temperature is higher than body temperature, the only way to lose heat is through evaporation. Human beings lose heat through sweating.
