Diagnoses requires the skills of a well trained specialist that is able to infer and separate the signs of it from other ailments. Medication alone does not cure it and most often it requires the efforts of both the child and that of the parent as well.

During gas exchange in the tissues
Georgia [21]

Answer:

E. a, b and c

Explanation:

Gas exchange near tissues: Near the tissues the partial pressure of oxygen is less so oxyhemoglobin in the blood immediately dissociates to give away oxygen to the tissues.

Near the tissues the metabolized product carbon dioxide is more i.e. the partial pressure of carbon dioxide is more near tissues. A rise in partial pressure of CO2  of fall in pH, decreases oxygen affinity of hemoglobin, this is referred as Bohr's effect. Hemoglobin undergoes conformational changes that facilitates the release of oxygen.

Carbon dioxide must be transported from tissue to lungs for exhalation process. For this some part of CO2 (20-25%) binds with hemoglobin and gets transported as carbaminohemoglobin (HbCO2). Around 70% of CO2 is transported in the form of bicarbonate ions and the remaining 7% in the dissolved form in plasma.

Oxidising agents *
NNADVOKAT [17]

Answer:

Option A. are mostly non-metals.

Explanation:

Oxidising agents are mostly non-metals because non metals gains electron from the metal during chemical bond and we know that oxidising agent is electron accepter not donar. For example, Sodium is a metal react with chlorine which is a non-metal so the sodium losses electron and this electron is gain by chlorine atom forming sodium chloride. In this example chlorine is a non-metal which gains electron.

DNA replication
-BARSIC- [3]

Answer:

Uses each strand of a DNA molecule as a template for the creation of a new strand. (Option A)

Explanation:

DNA replication: It is defined as the uses of each strand of a DNA double helix act as a template for the creation of a new complementary strand. During the process of DNA replication, one leading strand (new strand) is made as a continuous piece and another lagging strand is made in small pieces.

DNA replication process, in addition to DNA polymerase, requires other enzymes such as DNA ligase, DNA helicase, DNA primase, and topoisomerase. DNA polymerase is the key molecule in the DNA replication, it is responsible for the synthesizing DNA. They help to add one by one nucleotide to the growing DNA chain and incorporating only those which are act as complementary to the template.
