The answer is C. It's kind of like how humans speak in different languages. So do birds. They may make different noises but they are all still birds.

Then cross multiply.... 110 times x = 110x

then all that's left is to divide.

94000/110 :) = 854.46

Will there be water flow into or out of the fish without proper homeostatic processes? Will the fish experience "bloating" or "d

ikadub [295]

(Question 1 points 3)

No. There will be no water flow into or out of the fish without proper homeostatic processes. The body temperature of fish is regulated by the temperature of the water. the fishes only allow the solvent (water) to move across, but not the solutes. A fish is, after all, a collection of fluids floating in a fluid environment.

(Question 2 points 3)

The fish will not experience "bloating" or "dehydration” because in nature all organisms maintain normal conditions through homeostasis. It is the tendency toward a relatively stable equilibrium maintained by physiological processes by the body. Gills of fishes, enzymes help in maintain. Humans drink water in case of dehydration.

(Question 3 points 3)

Fish are the cold-blooded creatures of God. Most of the fishes cannot control their internal body temperature by themselves just like human beings. In order to stay at a normal and a healthy temperature, or to obtain temperature homeostasis, the fish seek warmer or colder water for water retention when they face the excessive water loss.

Cystic fibrosis is an autosomal recessive disorder. In one population, the frequency of affected individuals (A 2 A 2) is 0.0004

Simora [160]

Hardy Weinberg Equilibrium

Explanation:

Hardy Weinberg Equilibrium formula for allelic frequency is: $p+q=1$

Hardy Weinberg Equilibrium formula for genotypic frequency is: $p^2+q^2+2pq=1$

Here, $p$ =frequency of dominant allele

$q$ =frequency of recessive allele

$p^2$ =frequency of dominant genotype

$q^2$ =frequency of recessive genotype

$2pq$ =frequency of heterozygous genotype

frequency of affected individuals=0.0004(given)

here,affected individuals means the one's having Cystic Fibrosis and since it is recessive disease so we can write frequency of recessive genotype as: $q^2$ =0.0004

If $q^2$ =0.0004 $q$ will be 0.02;frequency of recessive allele will be 0.02

Using the formula $p+q=1$

$p+0.02=1\\p=1-0.02=0.98$

hence,frequency of dominant allele will be 0.98

Frequency of dominant genotype will be $p^2=(0.98)^2=0.9604$
Frequency of heterozygous genotype will be $2pq=2*0.98*0.02=0.0392$
