Two cell divisions mitosis or meiosis
Troyanec [42]
Cell division is the process by which a parent cell divides into two or more daughter cells.[1]Cell division usually occurs as part of a larger cell cycle. In eukaryotes, there are two distinct types of cell division: a vegetative division, whereby each daughter cell is genetically identical to the parent cell (mitosis),[2] and a reproductive cell division, whereby the number of chromosomes in the daughter cells is reduced by half to produce haploid gametes(meiosis). Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division, and sister chromatids are separated in the second division. Both of these cell division cycles are used in the process of sexual reproduction at some point in their life cycle. Both are believed to be present in the last eukaryotic common ancestor.

Prokaryotes (bacteria) undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells. All cell divisions, regardless of organism, are preceded by a single round of DNA replication.

For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction – an entire new organism is created. On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings. Mitotic cell division enables sexually reproducing organisms to develop from the one-celled zygote, which itself was produced by meiotic cell division from gametes. After growth, cell division by mitosis allows for continual construction and repair of the organism.[3] The human body experiences about 10 quadrillion cell divisions in a lifetime.[4]

The primary concern of cell division is the maintenance of the original cell's genome. Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells.[5] A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations.

Consider the motion diagram. It illustrates a car's velocity (V) and acceleration (A). Determine is there is a change in either
aleksandrvk [35]

Answer:

Change in velocity: yes

Change in acceleration: no

Explanation:

The diagram of the problem is missing: find it in attachment.

In the diagram, there are represented:

- The velocity of the car, as a vector labelled with V

- The acceleration of the car, as a vector labelled with A

The directions of the vector represent the direction of the velocity and the acceleration, while the length of the arrows represent the magnitude of the two quantities.

We observe that:

- For the velocity, the direction is always to the right; however, the length of the arrow decreases, so the magnitude of the velocity keeps decreasing

- For the acceleration, the direction is always to the left; and the length of the arrow remains constant, therefore the magnitude of the acceleration does not change.

This means that the car is moving to the right, but it is slowing  down, since the direction of the acceleration is opposite to the direction of the velocity.

The existence of brain areas like wernicke's and broca's areas support which linguist's beliefs about language development?
mel-nik [20]

The existence of brain areas like Wernicke's and Broca's areas support Noam Chomsky's beliefs about language development.

Noam Chomsky is well known for his work on linguistics, especially, the evolution of transformational grammar. He presumed that formal grammar was directly accountable for an individual's capacity to comprehend and interpret basic pronouncements.

The Wernicke's Area is the region of the brain critical to language development. It is situated in the temporal lobe on the left hemisphere of the brain. Its functions involve language comprehension, semantic or grammar processing, language identification as well as language interpretation.

The Broca's area helps create speech sounds, whereas, the Wernicke's area contributes to comprehension of language.
