I believe this problem has the following choices:

 

a. It was hard to get the fish to breed and produce offspring for the aquaculturist to raise.

b. Because the fish were stressed in tanks, they required much more food, reducing the profitability of rearing the fish this way.

c. The fish had to be raised in a community with several species of fish in the same tank, and they would attack and eat each other.

d. Marine fish are more aggressive than their freshwater relatives and they tended to fight a lot, often killing some of the other fish in the tank.

 

The correct answer is:

c. The fish had to be raised in a community with several species of fish in the same tank, and they would attack and eat each other.

Let p = purple flowers and p = white, and t = tall plants and t = dwarf. if the uppercase letters represent the dominant alleles
sesenic [268]

If the uppercase letters represent the dominant alleles, purple flowers and tall are the phenotype of a plant with the genotype Pptt.

A gene can exist in different forms across organisms. These different forms are known as alleles.

The subsequent combination of alleles that an individual possesses for a specific gene is their genotype.  

Examples of  genotype include:

  • Hair colour
  • Height
  • Shoe size
  • Eye colour

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not.

Whilst a phenotype is influenced the genotype, genotype does not equal phenotype. The phenotype is influenced by the genotype and factors including:

  • Epigenetic modifications
  • Environmental and lifestyle factors

Observing the phenotype is simple – we take a look at an organism’s outward features and characteristics, and form conclusions about them. Observing the genotype, however, is a little more complex.

Genotyping is the process by which differences in the genotype of an individual are analyzed using biological assays. The data obtained can then be compared against either a second individual’s sequence, or a database of sequences.

How are stem cells similar to cancer
Igoryamba

cancer cells are cells that divide and reproduce abnormally with uncontrolled growth... the stem cell theory of cancer proposes that among all cancerous cells, a few act as stem cells that reproduce and sustain the cancer, similar to normal stem cells normally renewing and sustaining our organs and tissues.

Catheter was used to remove excess fluid from pleural space. it is necessary to drain air, secretions and blood from thoracic space in order to allow normal expansion of lungs. when surgeon places a catheter in the chest, they provide a drainage route that removes excess air and other body fluids that may build up. in some occasions two catheters are installed after surgery, one posteriorly and the other anteriorly.
