You will frequently be called upon to deal with internal bleeding. Blunt trauma is the leading cause of internal injuries and bleeding. Which of the following are mechanisms of blunt trauma that may cause internal bleeding? 1. Falls 2. Motor vehicle or motorcycle crashes 3. Auto-pedestrian collisions 4. Blast injuries

2. Motor vehicle or motorcycle crashes

Explanation:

Blunt trauma is the initial trauma from which more common forms arise such as  abrasions, l, contusions, acerations, internal bleeding and/or bone fractures.

It can quickly lead to exsanguination, hemorrhagic or hypovolemic shock, and death if penetrating trauma occurs in blood vessels close to the heart. Another source of vascular damage that can lead to internal bleeding is blunt trauma. This can happen in an automotive crash following a high speed deceleration.

Several motor vehicle or motorcycle crashes causes internal bleeding in abdominal cavity which damages ribs as well.

Hence, the correct option is 2. Motor vehicle or motorcycle crashes.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
