Answer: The correct answer is D. Natural disaster

The density dependent factors are those whose impact on the population growth is different with varying population density.

In the given options, A. Predation  B. Parasitism  C. Competition are density dependent limiting factor. This is because they all are dependent on population density. For instance, competition for food and other resources is high when there is large population in a particular area.

On the contrary, Natural disaster is not a density-dependent limiting factor. This is because its impact is not dependent on the number of individuals. For example- Earthquake is a natural disaster, which causes damage to all the life forms irrespective of the population size.

Thus, in an ecosystem, Natural disaster is not a density-dependent limiting factor.

Describe each of the following: <br> Sickle Cell Anemia <br> Diabetes <br> Acne <br> HELP!!
sergejj [24]

Answer:

1. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons.

Treatments: Blood transfusion

Symptoms: Pain

2. Diabetes is the <u>condition in which the body does not properly process food for use as energy</u>. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies.

3. Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acne is most common among teenagers, though it affects people of all ages.

Why can the same trna and rrna molecules be used to synthesize a wide variety of polypeptides
Drupady [299]

Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.

Explanation:

DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.

Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.

A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.

The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.
