1. The statement "Lambda transitions are exactly the same as other non determinism" is false because lambda transitions introduce additional choices

2. The statement "Non determinism only applies in the direction of the transition, just because an 'a' forces you to be in two states does not mean you cannot be in just one of the two alone via some other path" is false because non determinism affects overall paths.

3. The statement "If two states S1 and S2 both have lambda transitions to each other, they MUST be the same state" is false because lambda transitions allow non-equivalence.

1. Lambda transitions, also known as epsilon transitions, allow a state in a finite automaton to move to another state without consuming any input symbol. They provide additional flexibility and expressiveness to the automaton. Other non-deterministic transitions, on the other hand, are based on input symbols and determine the next state based on the current state and the input symbol.

2. Non-determinism in automata allows for multiple possible paths and states to coexist simultaneously. When an input symbol is encountered, the automaton can transition to multiple states at the same time, representing different possible outcomes. This means that even if an input symbol "a" forces the automaton to be in two states, it does not exclude the possibility of being in just one of the two states alone through some other path.

3. Lambda transitions can establish connections between different states in a finite automaton. If two states, S1 and S2, both have lambda transitions to each other, it means there is a circular dependency between them. However, this does not imply that S1 and S2 must be the same state. It is possible for distinct states to have lambda transitions that create a loop or cycle between them, allowing for non-trivial behavior within the automaton.

The answer is A

There is just one amino acid encoded by each codon. Because all species use the same amino acid as a code, codons are therefore universal in nature.

What is a codon?

Codons are units of genomic information made up of three nucleotides (trinucleotides) in DNA or RNA that code for a specific amino acid or indicate the end of protein production (stop signals). There are 64 distinct codons, of which 3 serve as stop signals and 61 identify amino acids.

The bases that make up DNA and the associated messenger RNA are called bases. These nucleotides are frequently identified in RNA by the letters A, U, C, and G. A codon is made up of three nucleotides. Such codons are abundant in messenger RNA and consist of a string of three bases followed by three more bases, three more bases, and so on. Each codon gives the cell instructions on whether to begin building a protein chain, add a particular amino acid to the expanding protein chain, or stop building a protein chain altogether. For instance, the messenger RNA codon GCA indicates that alanine will be added to the protein chain. The stop codon UAG in messenger RNA denotes the conclusion of protein production.

More than one codon can encode the same amino acid. Example: The six codons CGU, CGC, CGA, CGG, AGA, and AGG are used to code for arginine.

The nature of the codons is continuous and uniform.

Therefore, "It extends from one end of a tRNA molecule" is the right answer.

1. (A) The theory of evolution by natural selection was developed by Charles Darwin in 1850. The theory was supported by his observations of the natural world during his five-year voyage from 1831 to 1836. (B) Evolution by natural selection happens when the environment changes, organisms best suited for the new environment survive and reproduce. The favorable adaptation is passed on to the next generation. Over time, more and more organisms will have a favorable adaptation, and the population will evolve.

2. Similar traits and features among various species can provide evidence of common ancestry. It is likely that traits and features shared by a group of organisms were inherited from a common ancestor.

Similar traits and features due to common ancestry are known as homology. By studying the homology of organisms, we can infer how they are related. The more similarities organisms share, the more closely related they likely are.

3. Habitat loss is the primary cause of higher extinction rates. Other causes include habitat changes, over-exploitation of wildlife for commercial purposes, the introduction of harmful nonnative species, pollution, and the spread of diseases.

4. Fossils are essential evidence for evolution because they show that life on Earth was different in the past than it is now. Paleontologists have used fossils to study the changes that have occurred in creatures as life has evolved on Earth. Embryology proves our modern theory of evolution by the similar structures found in embryos. The greater the similarity in structure, the more closely related the species are, and the more recent their common ancestor is. Natural selection is a mechanism that enables evolution. In a population with genetic diversity, the individuals that are better adapted and possess favorable traits eventually gain an advantage. Over time, the traits of these successful organisms dominate, causing the entire species to adopt these changes.

5. Every form of life on Earth interacts over time with other organisms, as well as with its physical environment. For that reason, the evolution of one species influences the evolution of species with which it coexists by changing the natural selection pressures those species face. The classic examples of this sort of evolution, called coevolution, are predator-prey and host-parasite relationships.

Sugar and oxygen are removed from the blood primarily in the cells of body tissues during cellular respiration.

During cellular respiration, sugar (glucose) and oxygen are combined in the presence of enzymes within the cells to produce usable energy in the form of adenosine triphosphate (ATP). This process occurs in the mitochondria, which are organelles found in most cells. The mitochondria are often referred to as the "powerhouses" of the cells because they generate ATP through the breakdown of glucose and the utilization of oxygen.

Within the mitochondria, a series of biochemical reactions take place, collectively known as the citric acid cycle and the electron transport chain. These processes break down the glucose molecule and transfer high-energy electrons to generate ATP. Oxygen acts as the final electron acceptor in the electron transport chain, enabling the efficient production of ATP.

As glucose is broken down and ATP is produced, carbon dioxide and water are generated as byproducts. Carbon dioxide is transported back into the blood and carried to the lungs, where it is exhaled. Oxygen is continuously supplied to the cells through the bloodstream, ensuring the availability of this crucial molecule for cellular respiration.

Viroids are small infectious agents that consist of a single-stranded RNA molecule lacking a protein coat. They infect plants and cause various harmful effects.

Viroids harm plants primarily through two mechanisms:

1. Disruption of gene expression: Viroids can interfere with the normal functioning of plant cells by targeting specific RNA molecules involved in gene expression. They can bind to and modify host RNA molecules, leading to the disruption of essential cellular processes. This interference can result in stunted growth, distorted leaves, and reduced crop yield.

2. Induction of host defense responses: Viroids can trigger plant defense responses, leading to the activation of defense mechanisms such as the production of reactive oxygen species, synthesis of antimicrobial compounds, and changes in gene expression. These defense responses can be harmful to the plant itself, causing cellular damage and contributing to the overall decline in plant health.

In summary, viroids harm plants by interfering with gene expression and inducing defense responses, ultimately leading to impaired growth, altered morphology, and reduced productivity.
