<span>The answer is dendrites. The protoplasmic projections of the neuron join other neurons dendrites enabling ann intricate network of neural networks, especially in the brain. The junction at which their  join is called a synapse.  Impulse travel from these dendrites to the body of the cell (soma) and through the axon</span>

Alkaptoneuria is a recessive genetic disorder found among North American populations at a frequency of about 1 in 500,000 births
Dafna11 [192]

Answer:

The correct answer is - 1/41,493

Explanation:

Let assume the frequency of the two possible same allele genotype (dominant and recessive) in an inbred population is p and q. Then the frequency of heterozygotes (H) is denoted as:

2pq + 2pqF.  ( where F is the inbreeding coefficient).

The frequency of the two different hoozygotes in inbred population can be calculated as:

p2 + pqF and q2 + pqF. (Where p and q are the allele frequency of the dominant and recessive phenotype.

Given: Frequency of Alkaptonuria (q 2) = 1:500, 000

=> q = 1/707

p = 706/707 ( Approx values)

solution:

Inbreeding coefficient (F) = 1/64

Therefore,

Frequency of Alkaptonuria in second cousins= q 2 + pqF

= 1/500, 000 + (706/707 x 1/707) x (1/64)

= 1/500, 000 + 1/45, 248

= 1/41,493 (approx)

The Honeydough Bread factory produces 2,000 loaves of bread per day.
padilas [110]

Answer:

Bakers use yeast as a leavening agent in baking bread and other bakery products.

The yeast ferments the sugar present in the dough and converts it into ethanol and carbon dioxide.

Glucose or sugar + bakers yeast → ethanol + carbon dioxide

Carbon dioxide causes the dough to rise whereas alcohol or ethanol formed usually evaporates during the baking process.

Thus, the given blanks can be correctly filled up by alcohol fermentation and carbon dioxide.
