To answer this question we need to analyze each available option:

A. An angiogram. Is a procedure used to obtain x-ray images showing blood vessels of the heart as well as blood flux. So this is the correct answer.

B. Electroencephalogram. This is a study of the cerebral function based on its electric activity. So this cannot be.

C. Amniocentesis. Refers to a pregnancy test to diagnose genetic disorders in a fetus, using amniotic fluid, so this cannot be either.

D.. An echogram, which refers to an image created by sound waves of high energy, is an ultrasound so this cannot be.

In an investigation, plant cells are placed in water that has been tinted blue. The investigators observe the color of the cells
larisa [96]

Answer:

C

Explanation:

When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.

If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.

In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.

Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.

2. Being humans we have bilateral symmetry. What kind of symmetry do most cnidarians have and what
LiRa [457]

Answer:

See explanation:

Explanation:

Humans are the same, one side to the other. The human body is a mirror image, one side to the other. The cnidarian phylum does not necessarily have bilateral symmetry. Body forms like jelly fish, sea anemones, and coral are examples of cnidarians. Note that jelly fish may be somewhat symmetric, but not totally and not in the same way that the human body is.
