Answer:
Measurement (Count) of Cell Numbers:
1. Breed Method:
A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.
Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.
Both parents are normal. But, some of the kids have the disease. This indicates that the parents are heterozygous for the disease (let's use Dd). They are phenotypically fine because D is normal. But we know they must both carry the diseased d allele because their kids have the disease.
If you cross Dd x Dd you get DD, Dd, Dd and dd as the possible outcomes. But because each time they have a child they roll the dice as to which of the 4 above happens, they were unlucky as 3 of those times they got dd for their child...so 3 of them have the disease (and are dd). One is phenotypically normal but could still be Dd or DD.
Rubber or plastic cutlery are most likely to be most acceptable for a child, spoons are less dangerous and come in different colors and shapes so childs can get familiar with them and start the learning eating process by themselves, then they are presented with the fork, which also comes in different shapes and colors, this will complement the training for the infant.
Answer: d. motor
Explanation: Efferent neurons are motor neurons. They are called efferent neurons because they transport nerve impulses out of the central nervous system (CNS) to effectors such as muscles or glands.
