The answer is B. Because meiosis process produce genetically different, haploid cells. Also, meiosis basically happen to produce gametes. Gametes is haploid. So, the answer is B

Answer:

Explanation:

Meiosis is a type of cell division that results in four daughter cells with each having half the number of chromosomes as the parent cell. Because meiosis is the cell division employed in the production of gametes (reproductive cells), the reduction in chromosome number is very vital- without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes. Hence, the cell does this by undergoing two rounds of nuclear and cytoplasmic division; Meiosis I and Meiosis II. This is unlike mitosis that undergoes one round.

In Meiosis I, homologous chromosomes pair up and lie side by side to form a TETRAD or BIVALENT structure. After which the homologous pair become separated in anaphase I. After cytokinesis, two daughter cells with reduced chromosome number arises i.e. haploid, n

N.B: A normal diploid (2n) organism contains 46 chromosomes, hence after meiosis I, two haploid daughter cells with 23 chromosomes (n) each arises.

In Meiosis II, which is similar to mitotic division, the individual chromosomes (sister chromatids) in each cell are pulled apart and separated to each pole. After cytokinesis, a total of four daughter cells arise. Since Meiosis II is similar to mitosis, no reduction occurs again. Hence, the four daughter cells or gametes will be haploid (n) in chromosomal number.

The four daughter cells are genetically different because meiosis creates new combinations of genetic material in each of the four daughter cells. Specifically, these new combinations result from the exchange of DNA between paired chromosomes in Prophase of meiosis I. This genetic exchange, called CROSSING-OVER or RECOMBINATION, means that the daughter cells produced through meiosis exhibit an amazing range of genetic variation unlike mitosis that produces genetically identical cells.

To keep the humeral head centered within the glenoidal cavity the rotator cuff muscles must be __________. Select to launch anim

enyata [817]

Answer:

<h2> located in the same plane</h2>

Explanation:

Such types of muscles and tendons that play an important role in the stabilization of the shoulder are called rotator cuff muscle.
These muscles are responsible for the different types of motion and simply called a different range of motion.
Muscles like scapulohumeral muscles, infraspinatus muscle and some others are grouped as rotator muscle.
These muscles are involved in the movement of the shoulder and also stabilize the joints of the shoulder for the movement and during the movement.
When the humeral head is centered within the cavity of the glenoidal then the rotator cuff muscle should be on the same plane.

In the cranial nerve model, which best describes the location of the optic chasma:________

eimsori [14]

Answer:

<u>Cranial Nerves:</u>

The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.

<u>The 12 pairs of the cranial nerves are as as under:</u>

The olfactory nerve
The optic nerve
The oculomotor nerve
The trochlear nerve
The trigeminal nerve
The abducens nerve
The facial nerve
The vestibulocochlear nerve
The glossopharyngeal nerve
The vagus nerve
The spinal accessory
The hypoglossal nerve,

It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-<em>Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.</em>

Explanation:

<u>Optic chasma:</u>

The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.

What size (internal diameter) endotracheal tube should be used to intubate a newborn with an estimated gestational age of 26 wee

Alecsey [184]

The size of endotracheal tube that should be used to intubate a new born with an estimated gestational age of 26 weeks is 2.5 mm (internal diameter). An endotracheal tube serves as open passage through the upper airway. The purpose of endotracheal intubation is to permit air to pass freely to and from the lungs inorder to ventrate the lungs.
