DNA is 99.9% identical from person to person as individual although 0.1% difference doesn't sound like a lot it actually represents millions of different locations within the genome where variation can occur.

What is DNA ?

DNA is the hereditary material in humans and almost all other organisms the molecule inside cells that contain the genetic information responsible and function of an organism.

DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases such as:

Adenine (A), cytosine (C), Guanine (G), thymine (T).

Therefore DNA is 99.9% identical for individual its  a hereditary material in human and almost all other organisms.

(a) Identify the insertion for the biceps brachii during flexion of the forearm: (b) Identify the insertion of the brachialis muscle during flexion of the forearm: (c) Identify the antagonist during flexion of the forearm: (d) Given its insertion, describe the forearm movement during which the biceps brachii is the prime mover:

Answers

(a) The insertion for the biceps brachii during flexion of the forearm is the radial tuberosity of the radius bone. (b) The insertion of the brachialis muscle during flexion of the forearm is the coronoid process of the ulna bone.

(c) The antagonist during flexion of the forearm is the triceps brachii muscle, which extends the forearm. (d) When the biceps brachii contracts, it causes flexion of the forearm at the elbow joint. This movement is called elbow flexion and is used in activities such as lifting objects and performing bicep curls. The biceps brachii is the prime mover in this movement because it is responsible for initiating and carrying out the majority of the movement.


(a) During flexion of the forearm, the insertion for the biceps brachii is the radial tuberosity. (b) The insertion of the brachialis muscle during forearm flexion is the ulnar tuberosity. (c) The antagonist during flexion of the forearm is the triceps brachii. (d) Given its insertion, the biceps brachii acts as the prime mover during supination and flexion of the forearm, allowing the hand to rotate outward and the elbow to bend.

In noncyclic photophosphorylation, the electrons passed down through the electron transport system are obtained from?.

Answers

In non cyclic photophosphorylation, the electrons passed down through the electron transport chain are obtained from water.

Non-cyclic phosphorylation have two Photosystems;

1. photosystem I

2. Photosystem II.

They work in series, first PS II and then PS I and are connected through electron transport chain. Electrons moved from PS II and then passed on to PS I.

The release of electrons from PS II can be replaced by some other electrons which can be came by splitting of the water molecule. The complex responsible for splitting of water molecule is present on PS II. Water molecule is converted into H⁺ , O and electrons are released which can be move through electron transport chain.

The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as(1 point).

Answers

The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as Independent Assortment.

What is Independent Assortment?

Independent Assortment may be characterized as a type of law in which the two factors of each character assort or separate out independent of the factor of other characters at the time of gamete formation.

The principle of inheritance pattern was proposed by Mendel. Due to this, he was known as the Father of Genetics. The example of independent assortment includes the combination found in pea plants, such as round shape and yellow color, wrinkled shape, and green color, and round shape and green color.

Therefore, the independent assortment is defined as the mechanism by which the inheritance pattern of one gene will not affect the inheritance pattern of another gene.

TRUE or FALSE

1- Lambda transitions are exactly the same as other non determinism.

2- 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.

3- If two states S1 and S2 both have lambda transitions to each other, they MUST be the same state.

Answers

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.

an electron and a hydrogen ion

Answers

Answer: Two electrons and a hydrogen ion

Explanation: The light reactions use solar power to reduce NADP+ to NADPH by adding a pair of electrons along with a hydrogen nucleus, or H The light reactions also generate ATP by powering the addition of a phosphate group to ADP, a process called photophosphorylation.

The ingredients needed to transform NADP+ to NADPH are an electron and a hydrogen ion.

Nicotinamide adenine dinucleotide phosphate ion (NADP+) is an energy carrying ion which transfers high energy electrons from chlorophyll to other molecules during photosynthesis.

Photosynthesis is defined as the process by which green plants are able to manufacture their own food.

In the light stage of photosynthesis, the electron and hydrogen atom released during photolysis of water is picked up by the energy carrying ion NADP+.

This is then converted to NADPH, that is Nicotinamide Adenine Dinucleotide Phosphate Hydrogen.

Based on Table 1, the severe PKU condition is associated with a substitution mutation of Isoleucine to Threonine in the PAH enzyme.

What is the disease PKU?

PKU is brought on by mutations in the gene that produces the enzyme  PAH or phenylalanine hydroxylase. The body requires this enzyme to convert the amino acid phenylalanine into other compounds.

The amino acid phenylalanine, which is harmful to the brain system, accumulates as a result of PKU. PKU might result in intellectual problems if left untreated.

Severe PKU condition is associated with a substitution mutation of Isoleucine to Threonine in the PAH enzyme. This mutation results in less than 10% of the wild-type enzyme activity and leads to a phenylalanine blood concentration of over 1200-1800 UM and severe intellectual disability.

Alex poured some pond water into three beakers. She then put waterweed into each beaker. She put the beakers in different places.


b. In the school pond there were lots of water lilies with large leaves covering the surface. There were not many plants growing below the surface. Suggest a reason for this.

Answers

Answer:
The growth of waterweed plant is higher in beaker E.

Explanation:
The growth of waterweed plant is higher in beaker E because the waterweed absorb nutrients that is provided in the form of fertilizers. Fertilizers are the nutrients that is essential for the growth of plants. Those plants that has more nutrients available can grow faster than those plants which have no nutrients or less nutrients because these nutrients provides raw material for the formation of amino acids and enzymes that contributes in the growth and development of the body.

The most likely reason for this is because they don’t get any sunlight causing plants not being able to grow if there are plants covering the water. There will most likely be plants that are small and can get sunlight from the spots that show sunlight. But overall it will most likely be due to not enough sunlight and probably oxygen.

Answers

The original Dichaete female used in the first cross has the genotype Dd. The original hairy male used in the first cross has the genotype hh.

In the progeny of the first cross, half of the flies (both male and female) were dichaete. Since the parental female was dichaete (mutant phenotype), and all the progeny from this cross were dichaete, it indicates that the mutant allele for Dichaete is dominant.

In the progeny of the first cross, none of the flies were hairy. This means that the parental male used in the cross was not hairy (wild type), and none of the progeny inherited the hairy phenotype. Therefore, the mutant allele for hairy is recessive.

Since the mutant allele for Dichaete is dominant, and the female used in the first cross was dichaete, we can conclude that her genotype must be heterozygous (Dd) for the Dichaete allele.

In the progeny of the first cross, none of the flies were hairy, indicating that the original male used in the cross was not hairy (wild type). Therefore, his genotype for the hairy allele is homozygous recessive (hh).

So, to summarize:

The original Dichaete female used in the first cross has the genotype Dd. The original hairy male used in the first cross has the genotype hh.
