Which of the following anomalies is (are) possible if an exposure dose of 40 rad (400 mgy) were delivered to a pregnant uterus in the third week of pregnancy?
1. skeletal anomaly
2. organ anomaly
3. neurologic anomaly
a) 1 only
b) 1 and 2 only
c) 2 and 3 only
d) 1, 2, and 3

B) 1 and 2 only

Explanation:

Megagray mGy: is an SI unit of absorbed dose

Term anomaly  has different meaning in different field of sciences but in all cases it refers as a marked deviation from the normal standard.

Like in biology it refers as Chromosome anomaly, which is the disorder caused by a structural error in a chromosome. In this disorder number of chromosomes become excess or reduced in offspring.

Here in this question 40 rad when delivered to pregnant women causes both skeletal and organ anomaly.

answer is

human impact on the environment can be seen in the deterioration of the !

: )

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
