Answer: Radiography: projectional, a single image, used for mammography
Fluoroscopy: used a contrast agent or dye, live imaging, real-time monitoring.
Explanation:
Answer:
water contracts and ice sinks
Attached is an image that wherein the question is being referred from.
There are choices for this question namely:
A- gravity increased the downward flow of the trapped water
B- metabolism of the elodea plants absorbed CO2 from the water
C- heat from the light source caused the escape of dissolved gas
<span>D- light caused the elodea plants to photosynthesize, releasing O2 gas
</span>
The correct answer is that
light caused the Elodea plants to photosynthesize, releasing O2 gas. Choice A is not true as if gravity increased the downward flow of the water, then the model without light should have air accumulated in the test tube too. In Choice B, while it is true that the plant may have absorbed the dissolved CO2 in water, this does not explain why there is gas on top of the test tube. Choice C may only evaporate the water, not cause the escape of dissolved gases. In choice D, however, light caused the Elodea plants to perform photosynthesis releasing O2 gas compared to the other model without light wherein the plant cannot perform photosynthesis thereby not releasing O2 gas therefore no gas is seen on top of the test tube.
Answer:
The correct answer is b a mutation in a gene that codes for protein regulating cell division.
Explanation:
Cancer is a disease that result due unregulated cell divison.There are many tumor suppressor protein present in our body such as retinoblastoma tumor suppressor protein,p53 protein.
These tumor suppressor protein helps to carry out cell divison in a regulated fashion and send signal for division only to that cell that have undamaged DNA.
Mutation in the gene encoding tumor suppressor protein leads to development of cancer.
