Answer:
In order to be considered scientific, a hypothesis must be testable falsifiable and clearly stated
Explanation:
An approach that uses passive solar heating instead of electricity for businesses and homes is known as A. Daylighting.
<h3>What is daylighting?</h3>
This is the illumination of buildings with natural light through the practice of placing reflective surfaces so that sunlight can provide effective internal lighting.
Solar heating is the use of sunlight to heat water or air in the buildings using radiant light and heat which is harnessed using a range of technology such as solar power to generate electricity.
Hence, we can see that neither weatherizing, green roofing nor cool roofing is the answer because they do not deal with providing passive solar heating, but daylighting uses passive solar heating.
Therefore, the correct answer is option A.

Answer:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.
Chromosomes exchange genetic material in step 3.
<h3><u>Explanation</u>:</h3>
The meiosis is the type of cell division that takes place for gametogenesis. The meiosis has two phases - meiosis I and meiosis II.
The meiosis I has the events like crossing over and independent assortment which leads to the mixing of genes between homologous chromosome pairs and separation of homologous chromosome pairs. So the two cells that are produced from the meiosis I are genetically different. The step 3 shows the crossing over of prophase 1 of meiosis I. So, it shows the genetic difference between the offsprings and leads to genetic variation.
