<h2>Answer:</h2>
The offspring of long fins will be heterozygous dominant and of short fins will be homozygous recessive.
<h3>Explanation:</h3>
- Heterozygous long finned fish will have a genotype of Ll.
- Homozygous short finned fish will have a genotype of ll.
- The possible genotypes of their offsprings will be:
- Ll × ll
- Ll, Ll, ll, ll.
- The probability of short-finned fish will be 1/2 and the probability of long finned fish will also 1/2.
- So the short-finned offspring will be homozygous recessive and long finned will be heterozygous dominant.
The answer is <span>Chemical digestion involves the breaking down of food with enzymes; </span><span>mechanical digestion is breaking down food by chewing and tearing with teeth.
Mechanical digestion means breaking down food mechanically. By chewing and tearing with teeth, food breaks down into smaller parts and no enzymes are used. Chemical digestion means breaking down food in a chemical manner. This is achieved by secreting enzymes, which break down chemical bond between food molecules.</span>
In a population of 10,000 individuals, 300 men are afflicted with a recessive, x-linked disease. 18 woman would be expected to be afflicted in this population
both sickle cell disease and cystic fibrosis. dominant X-linked disease. Gene variations on the X chromosome are the root cause of X-linked diseases. A variation in the one copy of the gene present in each cell is what causes the condition in males (who have only one X chromosome).
Red-green color blindness and hemophilia A: Red-green color blindness are two examples of X-linked diseases. Red-green color blindness is simply the inability to distinguish between the many hues of red and green.
Males who are hemizygous (i.e., have only one X chromosome) will fully express an X-linked disease. Females, who have two X chromosomes, on the other hand, will typically be carriers of the abnormality and are hence typically asymptomatic.

Answer:
The phillipines are a free country if thats what you mean
Explanation:
Enzymes are biological catalysts which increase the rate of biochemical reactions without undergoing any change themselves. They bind with the substrate to form a enzyme substrate complex leding to the formation of product releasing free enzyme.
Enzymes have an optimum pH at which they show their maximum activity. Any change in the pH effects the enzyme and the enzymatic reaction. Most of the enzymes are functional at the neutral pH of 7 in the cell cytoplasm with a few exceptions. An acidic environment in the cell, changes the tertiary structure of the enzymes and the bonds of the enzymes are weakened. Thus, preventing the substrate binding to the active site of the enzyme and inhibiting catalysis. This is due to the change in the structure of the active site leading to the lack of electrostatic attraction between the enzyme and the substrate.
