Answer:
The <u>PCO₂</u> -carbon dioxide partial pressure- in the alveoli is 40 mm Hg and that of the blood entering the pulmonary capillaries is <u>45 mmHg</u>. This causes <u>carbon dioxide</u> to diffuse down its partial pressure gradient from the blood into the alveoli.
Explanation:
Gas exchange is a physiological process that involves the entry of oxygen into the body and tissues and the exit of carbon dioxide, a product of metabolic reactions.
At the pulmonary level, gas exchange occurs between the alveoli and the alveolar capillary, and the diffusion of gases across the alveolar-capillary barrier is dependent on a pressure gradient due to the partial pressure of gases.
In the case of CO₂ the diffusion goes from where the partial pressure is higher to where it is lower, i.e. <u>from the alveolar capillary, where the PCO₂ is 45 mmHg, to the pulmonary alveolus, where the PCO₂ is 40 mmHg</u>.

Answer:
Answer No 1:
The three ways evolution is determined to have occurred are:
A. Molecular similarities
C. Homologous structures
E. Fossil evidence
Explanation:
Since the theory of evolution became popular, scientists have been looking for similarities and differences among organisms so that they can compare which organisms have a more closer ancestor together as compared to other organisms. Scientists look for molecular similarities, such as the similarities in the proteins and other molecules to depict relations among organisms. Homologous structures is a common term in evolutionary studies in which organisms which are more closely related are known to be more similar. Fossil evidences also help a lot in evolutionary studies.'
Answer No 2:
The correct option is C. the most reproductively successful
Explanation:
Natural selection tends to favour the fittest organism. In evolution, 'the fittest; means the organism which have the ability to survive in an environment and to pass on its characteristics to its offspring. The organism which is more reproductively successful is considered to be more successful.
The correct answer is sex linkage.
Sex linkage refers to the phenotypic expression of an allele, which relies upon the gender of an individual and is directly associated with the sex chromosomes. These genes are regarded sex-linked as their expression and patterns of inheritance vary between the males and females. The sex linkage cannot be the same as genetic linkage, the sex-linked genes can be associated genetically.
