Answer:
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
Ans.
Photic response or sneezing due to exposure of bright sunlight is a genetically inherited trait. A given, both man and woman are showing photic response and are heterozygous (Hh) for the trait.
It indicates that 'the inheritance pattern for photic response is autosomal dominance,' means the mutated allele (H) for the trait is dominant over normal or recessive gene (h), and presence of only copy of it can shows its effect.
Thus, the correct answer is 'dominant-recessive.'
The rigth answer is 14.7N
The law of gravitation thus makes it possible to calculate a force exerted between two objects. In a terrestrial reference system, we can then calculate the force exerted between the Earth and an object.
The law applied in this case is P = mass x g (gravitational constant = 9.8 N / kg)
if a book weighs 1.5 kg then: P = 1.5 x 9.8 = 14.7N
Answer:
Fruting bodies
Explanation:
Fungi can produce spores on somatic hyphae or on special spore producing hyphae which are arranged into structers called fruting bodies.
A dead flu virus cell is injected into the body which in turn makes the body recognize the cell so that when an alive flu virus cell enters the body, the body knows what the foreign cell is and can successfully defend against it.
