The given statement "About 10% of the carbon dioxide carried in the blood is simply dissolved in the plasma." is false because about 10% of carbon dioxide (CO₂) carried in the blood is not simply dissolved in the plasma. The majority of CO₂ in the blood is transported in different forms.

One of the main ways CO₂ is carried in the blood is through its conversion into bicarbonate ions. This process occurs in red blood cells and is facilitated by an enzyme called carbonic anhydrase. Carbon dioxide diffuses into red blood cells, where it combines with water to form carbonic acid, which then dissociates into bicarbonate ions and hydrogen ions.

The bicarbonate ions are then transported out of the red blood cells and into the plasma, while chloride ions move into the red blood cells to maintain electrical neutrality (chloride shift).

The bicarbonate ions are the primary form in which CO₂ is transported in the blood, accounting for approximately 70% of the total CO₂ transport. Another portion of CO₂ binds directly to hemoglobin in red blood cells, forming carbaminohemoglobin, which accounts for about 20-25% of CO₂ transport.

Only a small fraction of CO₂ (less than 10%) remains dissolved in the plasma as a result of its solubility in blood. This dissolved CO₂ plays a minor role in overall CO₂ transport.

In summary, the statement that about 10% of the carbon dioxide carried in the blood is simply dissolved in the plasma is false. The majority of CO₂ is transported in the form of bicarbonate ions, with a smaller portion binding to hemoglobin, while only a small fraction remains dissolved in the plasma.

Mendelian inheritance states that traits are determined when offspring receive one allele for each trait from each parent.

Mendelian inheritance, named after the Austrian monk Gregor Mendel, explains how traits are passed on from parents to offspring. The basic principle of Mendelian inheritance is that traits are determined by the inheritance of alleles, which are different forms of a gene.

1. Alleles: Genes exist in pairs, with one allele inherited from each parent. These alleles can be either dominant or recessive. Dominant alleles exert their effects even if only one copy is present, while recessive alleles require two copies to be expressed.

2. Gamete Formation: When an organism produces gametes (sperm or eggs), it undergoes a process called meiosis. During meiosis, the pairs of alleles separate, so that each gamete receives only one allele for each trait.

3. Fertilization: When two gametes (one from each parent) combine during fertilization, the resulting offspring inherits one allele for each trait from each parent. This is why offspring typically exhibit a combination of traits from both parents.

4. Punnett Square: To predict the possible combinations of alleles in offspring, a Punnett square can be used. This is a grid that helps determine the probability of different genotypes and phenotypes.

5. Dominant and Recessive Traits: If a dominant allele is present, it will be expressed in the offspring's phenotype. However, if both alleles are recessive, the recessive trait will be expressed.

Overall, Mendelian inheritance provides a framework for understanding how traits are inherited and passed down from one generation to the next through the transmission of alleles from each parent.

The formation of a simple lipid bilayer membrane would not be sufficient for the origin of the cell because a cell requires more than just a physical barrier to separate itself from the environment. While a lipid bilayer can provide a basic barrier to separate the internal and external environments, it cannot perform essential functions required for cellular life.

For instance, in order for a cell to survive, it needs to have the ability to maintain a stable internal environment, a process known as homeostasis. A lipid bilayer alone cannot regulate the flow of molecules and ions across the membrane to maintain a stable internal environment. Therefore, the membrane would need to have specialized proteins that allow for the selective transport of molecules and ions in and out of the cell.

Additionally, a lipid bilayer alone cannot carry out metabolic reactions required for cellular functions. Enzymes and other proteins are required for cellular metabolism, which would need to be present within or attached to the membrane.

5-element DNA sequences that -

(a) end with A - 256 sequences

(b) start with T and end with G - 64 possible sequences

(c) contain only A and T - 32 possible sequences

(d) do not contain C - 243 possible sequences

(a) To find the number of 5-element DNA sequences that end with A, we need to calculate the possible sequences for the first four positions.

Since there are 4 types of bases (A, T, C, and G), there are 4 choices for each position.

Therefore, there are 4^4 = 256 possible sequences that end with A.

(b) To find the number of DNA sequences that start with T and end with G, we need to calculate the possible sequences for the three middle positions.

Since there are 4 choices for each position,

there are 4^3 = 64 possible sequences that start with T and end with G.

(c) To find the number of DNA sequences that contain only A and T, there are 2 choices (A or T) for each of the 5 positions in the sequence.

Therefore, there are 2^5 = 32 possible sequences containing only A and T.

(d) To find the number of DNA sequences that do not contain C, we need to consider the sequences made up of the remaining 3 bases (A, T, and G).

There are 3 choices for each of the 5 positions, so there are 3^5 = 243 possible sequences that do not contain C.

Nerve Plexus is a complex, interconnected neural network formed by neurons of the sympathetic and parasympathetic divisions. The correct option is A.

A nerve plexus refers to a complex, interconnected network of nerves formed by the branching and merging of nerve fibers from multiple spinal nerves. It is found in the peripheral nervous system (PNS) and serves as a distribution center for nerve impulses. Nerve plexuses are responsible for providing innervation to specific regions or organs of the body.

The nerve fibers that contribute to a nerve plexus come from neighboring spinal nerves, typically in close proximity to each other. As these nerve fibers approach the plexus, they intertwine and divide into various branches, which then recombine with fibers from other spinal nerves. This branching and merging pattern creates a network that allows for more efficient communication and coordination of nerve impulses.
