<h3>What is
blood pH?</h3>
Blood pH can be defined as a measure of the molar concentration of hydrogen ions that are present in the blood of a living organism, with respect to its acidity, neutrality or alkanlity (basicity).
In response to a notification of a <u>decrease</u> in blood pH by the nervous system, the brain would send signals (impulses) to the external intercostal muscles and the diaphragm through its respiratory center, so as to help the living organism increase its breathing rate and the volume of its lungs during inhalation.

<span>Constructing recombinant DNA or rDNA scientists
should combine both DNA from two different species. Based on study, rDNA
is possible if both DNA that should be combined should have the same chemical </span><span>structure.
Most o the DNA do have the same structure they only differ in nucleotide
sequence. </span>
The correct answer is:
C) outer covering
The structure that you should expect to find in a single celled organism is : C. outer covering.Single celled organism still hasn't developed a complex body structure, so it definitely won't have legs, internal organs, or brain.
Explanation:
None of the other answers can happen due to the combined solutions disability to reach the center of the organism, smaller cells in higher numbers are more effective as they can group commonly yet all receive the right amounts of nutrients for its need. multicellular organisms, such as humans can have the other answers in them as cells group collectively to make skin, muscles, and organs. it also provides the body to grow larger.

1.Frost Wedging (Freeze-Thaw)
Water expands by 9 percent when it freezes. As it expands, it exerts up to 4.3 million pounds per square foot of pressure. Since water seeks low points, repeated freezing and thawing can lead to deep vertical fissures as cracks are extended downward. Cracks that allow entry of roots lead to similar wedging.
2.Crystal Formation
Crystal formation cracks rock in a similar way. Most water contains dissolved salts. When water in rock fissures evaporate, the salt concentration increases, which leads to crystallization. This occurs in arid regions where the humidity fluctuates widely, so that the salt can be redissolved and carried into new fissures.
