A fish that normally lives in salty water is placed in a tank containing fresh water. What do you think will happen to the cells of the fish?

Answers

Answer 1
Answer: Well, freshwater doesn't have the salt that a saltwater fish needs so the fish's cells(hypertonic cells) would become hypertonic which cannot mix with that fish's structure. Therefore, the fish, well, the fish would die.

What is some conlusive evidence that organisms of two different species share a common ancestor?

Answers

Well, according to the theory of evolution, the reason that organisms of two different species would share a common ancestor is that way back before evolution really took place, there were species that were all grouped together. After time, these species needed to evolve in order to adapt to the way the environments were changing. For example, dogs and wolves are not the same species, but are related and share a common ancestor, causing them to look alike.

What is the advantage of genetic recombination as a mode of reproduction in bacteria? less time finding other bacteria

higher rates of reproduction

more susceptibility to antibiotics

greater genetic variation

Answers

Bacterial genetic recombination is characterized by DNA transfer from one organism called donor to another organism as the recipient and the result is the production of genetic recombinants, individuals. Those recombinant bacteria have a greater genetic variation because they carry, not only the genes they inherited from their parent cells but also the genes introduced to their genomes. There are three types of mechanisms that create genetic variations in bacteria (through recombination):

1. Transformation-that occurs when bacterium takes up a piece of DNA floating in its environment,

2. Transduction-occurs when DNA is accidentally moved from one bacterium to another by a virus (bacteriophage) and

3. Conjugation- when DNA is transferred from one bacteria to another through a tube between cells.

 

Those mechanisms of genetic recombination together with short generation time and random mutations allow bacteria to evolve very quickly and for example, create resistance to antibiotics.
The correct answer for the question that is being presented above is this one: "greater genetic variation."  The advantage of genetic recombination as a mode of reproduction in bacteria is that it has greater genetic variation. The greater its genetic variation, the greater advantage of genetic recombination.

Choose the incorrect statement regarding bile.A. Bile is both an excretory product and a digestive secretion.
B. Bile functions to emulsify fats.
C. Bile functions to carry bilirubin formed from breakdown of worn-out RBCs.
D. Bile contains enzymes for digestion.

Answers

The incorrect statement regarding bile is that bile contains enzymes for digestions. As a matter of fact, it doesn't.

Final answer:

The incorrect statement regarding bile is option D, which states that bile contains digestive enzymes, which is false. Bile helps in the digestion of fats by emulsifying them but does not contain the enzymes that break them down.

Explanation:

The incorrect statement about bile is option D. Bile does not contain digestive enzymes. This is a common misconception because bile does play a crucial role in digestion, particularly in the digestion of fats. Bile is produced by the liver and stored in the gallbladder. During digestion, bile is released into the small intestine where it emulsifies fats, i.e., breaks fats into tiny droplets. This increases the surface area of the fats, facilitating their digestion by enzymes called lipases which are not contained in the bile but are secreted by the pancreas. In addition to this, bile helps in the excretion of bilirubin, a byproduct of the breakdown of worn-out red blood cells.
