Which of the following is the correct term for a small hole in a seed’s outer layer, allowing water and nutrients access to the seed? a.) hypocaust b.) micropyle c.) dermal pore d.) apical meristem

The correct option is B which is micropyle.

Explanation:Generally micropyle is known as the opening in the ovule or egg from which sperm enters the egg.But at the time of germination it is used to absorb water and nutrients.It is the micropyle from which the root emerges from the seed.

1. These animals are grouped in phylum vertebrata or “animals with backbone”. All of these animals possess a vertebral column as a form of internal support (in contrast to invertebrates wherein they rely to exoskeleton, rigid body parts, or have no form of support at all). These different animals are grouped separately by class. 

2. The right side of the heart will receive carbon dioxide rich blood from the body through the superior and inferior vena cava (systemic veins) then it will be pumped through the pulmonary artery to the lungs where blood will be oxygenated and converted to oxygen rich blood. The left side of the heart will receive the oxygen rich blood and will be pumped to the body through the aorta (systemic artery). From the body, the blood will go to the right side of the heart again hence repeating the cycle. 

3. Charles Darwin’s most popular contribution to science is that proposed and defended the theory of evolution. He did this by studying animal lineages and publishing his work “On the Origin of Species by Means of Natural Selection” on 1859

4. Feedback inhibition helps maintain the body temperature by having our sense organs (i.e. skin) detect heat or cold. If it detects heat, then the response of the body is to sweat and once its cool enough again, the body stops sweating (negative feedback). Same goes if the body is cold, the response is shivering and once the body is out of the cold, the body stops shivering. 

5. Villi are gross finger-like projections in the intestinal lumen and it functions to increase the absorptive surface area of the intestines hence efficiently absorbing nutrients. Lack of villi will decrease nutrient absorption and may lead to malnutrition.
