Mitosis consists of four basic phases: Prophase, Metaphase, Anaphase, and Telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.

A. Prophase

B. Metaphase

C. Anaphase

D. Telophase

The third stage of mitosis, known as metaphase, is when the genetic material that was replicated and carried in the parent cell's nucleus is split into two identical daughter cells.

There are four fundamental stages of mitosis: prophase, metaphase, anaphase, and telophase.

Cytokinesis, which is the process of separating a cell's contents into two new cells, begins in either anaphase or telophase, where the phases are strictly sequentially ordered.

The division of the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells is called mitosis, and the process begins with the prophase.

Answer:

The alleles for MADS-box genes get expressed at different levels. They form the “L” complex and the “SP” complex. These are a group of proteins that determine the shape of the petals. The more they L complex is expressed, the high the probability that the petals of the flower will form the ‘lip’ and the high the SP complex is expressed then the high the likelihood of dominant petals.

Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant  produced. This is common in premature infants.

Explanation:

Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.

It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.

Answer: The arrangements and correct order of the above described genetic and behavioural adaptations includes:

A.) Camouflage: This is a survival adaptation by which an animal blends in and is hidden in its surroundings.

B.) Mimicry: This is an organism exhibiting characteristics similar to one known to be dangerous.

C.) Tropism: This is the growth or movement of an organism ( usually plant) in response to a stimulus.

D.) Venom: This is a poison secreted by animals for either defensive or offensive purposes.

E.) Mutualism: This is the interaction of two organisms where both benefits.

F.) Commensalism: This is the interaction of two organisms where one is helped and the other is neither helped nor harmed.

Explanation:

In the study of organisms and it's environment, they are able to adapt through genetic and behavioural mechanisms. Adaptation of defined as the ability of organisms to become fitted to its environment by modifying or changing its features. These features may be structural or behavioural.

STRUCTURAL ADAPTATION: Almost every part of the body of a living organism is structurally adapted to its mode of life. They are structurally adapted for the following specific functions:

--> Escape and defence: many animals use CAMOUFLAGE to remain unnoticed by potential predators. While some others are capable of producing poisonous VENOMS which may become offensive to the predators. Also many harmless organisms may possess structural behaviours that may MIMIC dangerous organisms thereby keeping their predators at arms length.

--> obtaining food: organisms needs to possess some structural features that will enable them obtain food in their environment. This usually leads to forming various feeding relationship ( which may be MUTUALISTIC or COMMENSALISM) with one another to be able to obtain food for survival.

BEHAVIOURAL ADAPTATION: Behaviour is everything an organism does in response to changes in its environment. Plants do exhibit behavioural adaptations and a typical example is the phototrophic movement of plant shoots which is a type of TROPISM.

The following pieces of evidence does not mid-ocean ridges are formed Mid-ocean ridges are found on the bottom of most oceans.

The central parts of the oceans have mid-ocean ridges. The mid-ocean ridges are volcanic underwater mountain ranges.

There is constant propelling of magma, and as the magma cools off quickly it creates new crust.

This results in the mid-ocean ridges gaining heights of up to 1.5 km above the surrounding area.

So, option B is correct.

Answer: a frame shift mutation

Explanation:

ACGGGCAAACGATTG  to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines. as there is a deletion of a single base, ,so it is called a deletion mutation.

This change can have various effects on the resulting protein, depending on the specific location of the mutation within the gene and the role of the affected amino acid in the protein's function. For instance, in a non-coding region of the gene, such a mutation might have no effect at all on the protein, as it would not affect the sequence of the mRNA that is transcribed from the gene. However, if the mutation occurs in a coding region of the gene, it can lead to a change in the resulting protein.

Hence, ACGGGCAAACGATTG  to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines.

Answer:

b

Explanation:

Natural selection will  only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.

Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.

Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.

Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,

These are the conditions that are said to be both necessary and sufficient for natural selection.

Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.

Thus, the correct option is d.
