Looking at a standing human, what is the line that demonstrates the body's bilateral symmetry?
a. facing the side and drawing a line up and down the center of the body
b. facing the front and drawing a line up and down the center of the body
c. facing the front and drawing a line side to side across the middle of the body
d. facing the top of the head and drawing a line across the head touching each ear

The correct answer is option B.

Explanation:

Human body has bilateral symmetry in them. The bilateral symmetry means that the body can be divided into exact same halves if a line is drawn down the center. Bilateral symmetry can be demonstrated in humans by facing towards the front and make a lineup and down the center of the body.

Bilateral symmetry creates a mirror image in the body by dividing it in right and left plane. It may assist your brain to understand make visual perception easier and if body is in different positions and.

Thus, the correct answer is option B.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
