What is the difference between limerick poems and concrete poems

Bess [88]

Concrete, pattern, or shape poetry is an arrangement of linguistic elements in which the typographical effect is more important in conveying meaning than verbal significance. It is sometimes referred to as visual poetry, a term that has now developed a distinct meaning of its own.

A limerick is a humorous poem consisting of five lines. The first, second, and fifth lines must have seven to ten syllables while rhyming and having the same verbal rhythm. The third and fourth lines only have to have five to seven syllables, and have to rhyme with each other and have the same rhythm.

Explain how it is possible for a compound to have both ionic and covalent bonds

pishuonlain [190]

Basically ionic bonds can be formed between a metal atom and something called a radical ion. The radical ion could have covalent bonds within themselves, for example, CO3- is a radical ion.

2. Beginning with the superior vena cava, trace the path followed by a red blood cell as it passes into and through the heart, t

Katen [24]

Answer:

BLOOD PATHWAY:

Body > superior and inferior vena cava > right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary artery > lungs > pulmonary vien > left ventricle > bicuspid/mitral valve> left ventricle > Aortic semilunar valve > Aorta > Body

The pathway goes like this:

From the body (we don't say first because this is a cycle), unoxygenated blood collected goes to the heart via the INFERIOR and SUPERIOR VENA CAVA then it empties into the RIGHT ATRIUM from there it passess through a valve called TRICUSPID valve, which prevents backflow of blood to the right atrium. The blood goes to our first pumping chamber, RIGHT VENTRICLE. The right ventricle pumps the blood through the PULMONARY SEMILUNAR VALVE which leads to the PULMONARY ARTERIES, which happens to be the only arteries that carry unoxygenated blood. From there it goes to the lungs to pick up oxygen and rid itself of carbon dioxide. The blood then goes back into the heart via the PULMONARY VEINS and like the latter, they are the only veins that carry oxygenated blood.

The blood then goes back into the heart, emptying into the LEFT ATRIUM. From there it goes through the BICUSPID VALVE or MITRAL VALVE and to the last and thickest pumping chamber, the LEFT VENTRICLE. The left ventricle pumps the blood through the AORTIC SEMILUNAR VALVE which opens out to the AORTA.

And at last, it goes back to your body.

The starting cell must duplicate its Chromosomes in interphase before mitosis can being? Does this change the number of chromoso

MArishka [77]

Answer:

The correct answer is both.

Explanation:

Each chromosome is made up of a pair of sister chromatids which remain attached to each other at the centromere.
During DNA replication the DNA duplicates, which means that if initially in the parent cell 'n' chromosomes were present then, after duplication, the number of chromosomes in the cell will be '2n'.
As mentioned above, each chromosome has a pair of sister chromatids, that is, two chromatids per chromosome. So, 'n' chromosomes will have '2n' chromatids. Hence, '2n' chromosomes will have '4n' chromatids.
In a parent cell,

Before duplication, number of chromosome = n, number of chromatid = 2n.
After duplication, number of chromosome = 2n, number of chromatid = 4n.

The cell cycle proceeds as, G0, G1, S, G2, M.
G0 represents the interphase. It occurs before replication or duplication of the chromosomes, which occurs in the S phase.
So, in G0 phase, the chromosome number is 'n' and chromatid number is '2n'.
