Electricity is the movement of free electrons from a0 charged areas to a1 charged areas.

klasskru [66]

The answer is; negative…positive

In a closed circuit, electrons move from the negative node to the positive node. Electric current, on the other hand, flows from the positive node to the negative node. The flow of electrons and electric current is measured in amperes (A).

Why are the spores of fungi kept inside a globe like structure

frozen [14]

The fungi comprise a diverse group of organisms that are heterotrophic and typically saprozoic. In addition to the well-known macroscopic fungi (such as mushrooms and molds), many unicellular yeasts and spores of macroscopic fungi are microscopic. For this reason, fungi are included within the field of microbiology.

Fungi are important to humans in a variety of ways. Both microscopic and macroscopic fungi have medical relevance, with some pathogenic species that can cause mycoses (illnesses caused by fungi). Some pathogenic fungi are opportunistic, meaning that they mainly cause infections when the host’s immune defenses are compromised and do not normally cause illness in healthy individuals. Fungi are important in other ways. They act as decomposers in the environment, and they are critical for the production of certain foods such as cheeses. Fungi are also major sources of antibiotics, such as penicillin from the fungus

Consider the following chromosomes and if they are affected by hemophilia.

Inga [223]

Answer:

B. 1/2 and 1/4

Explanation:

Hemophilia is a rare disease that has to do with the inability for blood to clot. It is inherited on the X chromosome, hence, it is said to be X-linked. It is usually passed from mother to son. According to this question;

X - unaffected X chromosome

x = X chromosome affected by hemophilia

Y = Y chromosome

Therefore, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:

Xx- X and x gametes

XY- X and Y gametes

Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY will be possibly produced.

XX (1) - unaffected female

Xx (1) - unaffected but carrier female

XY (1) - unaffected male

xY (1) - affected male (have hemophilia)

Based on the questions;

- 2 out of the possible 4 children will have the affected chromosomes i.e. both xY son and Xx daughter have the affected (x) chromosome. Hence, the fraction is 1/2

- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.
