A shift to the right in the hemoglobin dissociation curve means that: the affinity of hemoglobin for O2 has decreased. the CO2 l

evels in the blood have decreased. the pH of the blood has increased. the hemoglobin protein has denatured. less O2 is released by hemoglobin to the body cells.

Answer:

The correct answer is - the affinity of hemoglobin for O2 has decreased.

Explanation:

The oxyhemoglobin dissociation curve or hemoglobin dissociation curve is the graphical representation of the proportion of hemoglobin in its saturated form on the y-axis against the prevailing oxygen tension P0 on the x-axis.

A shift of the curve to the right side indicates the hemoglobin has a reduced or less oxygen affinity. It occurs in cases where oxygen needs to be released such as the placenta for breathing of the fetus and muscles.

What condition occurs when fluid accumulates in the lungs, preventing them from breathing adequately?
Norma-Jean [14]

Answer: Pulmonary edema

Explanation:

Pulmonary edema is the condition in which there is an excess of fluid in the lungs. This fluid gets collected in the air sacs which causes hindrance in breathing.

Most of the heart related diseases causes pulmonary edema. Pulmonary edema can be caused due to pneumonia, trauma in the chest wall and exercising at higher elevations. It is very fatal if not cured on time.

Hence, the correct answer is pulmonary edema.

Place the events in the correct order:
Alecsey [184]

Answer:

1. Chromatin condense into chromosomes.

4. Homologous chromosomes pair up (formation of tetrads).

5. Homologous chromosomes separate and move to poles.

2. Sister chromatids separate.

3. Chromosomes unravel in to chromatin.

Explanation:

This question portrays the process of meiosis in a cell. The ordered sequence of events in the options are:

1. Chromatin condense into chromosomes - This process occurs in the Prophase stage. Prior to the cell division, the nuclear material is found as Chromatin material. This Chromatin material then undergoes condensation to form visible chromosomes.

4. Homologous chromosomes pair up (formation of tetrads) - This process also occurs during the Prophase stage of meiosis I. In this stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) are paired up side by side to form a structure known as TETRAD or BIVALENT.

5. Homologous chromosomes separate and move to poles - This process characterizes the Anaphase stage of meiosis I. Homologous chromosomes are pulled apart to opposite poles of the cell by spindle microtubules.

2. Sister chromatids separate - After meiosis I, meiosis II involving sister chromatids instead of homologous chromosomes follows. In the Anaphase stage of meiosis II specifically, sister chromatids are pulled apart towards opposite poles of the cell.

3. Chromosomes unravel in to chromatin - After the whole division process i.e. karyokinesis (division of the nuclear material), the chromosomes begin to unravel to form the CHROMATIN threads once again. This process occurs in the Telophase stage of meiosis.
