Which statement is an example of parasitism?

2 answers:

8 0

Because the parasite needs the host to remain alive, it is typically advantageous for the parasite NOT to kill its host, however there are examples of when death of the host occurs. An example of this is seen in the photo below. In the photo, a tomato hornworm is covered with cocoons of pupating braconid wasps.

The correct answer is B. Wasps lay eggs inside hornworms and after the eggs hatch, the wasp larvae feed on the hornworm.

Explanation:

In biology, parasitisms occur as one organism obtains one benefit from another organism that is known as a hostage, while the hostage is damaged or negatively affected by the parasite. This type of relationship can be seen in the case of lice as these organisms live on blood-warmed animals and feed on the blood of the hostage; additionally, the hostage is damaged not only because lice feed on its blood but because it can transmit certain diseases.

According to this, the statement that is an example of parasitisms is "Wasps lay eggs inside hornworms and after the eggs hatch, the wasp larvae feed on the hornworm" because in this case, the wasp is benefited by laying eggs inside a hornworm as this allow larvae to survive; also the host (hornworm) is damaged as it is eaten by the larvae.

The amount of sagebrush would increase, which would lead to an increased population of jackrabbits, as sagebrush their food source. As the amount of jackrabbits increase, it gets easier for coyotes to hunt for them which in return, increases their survival rate/population.

Answer:

Diagram, in attachments

Explanation:

From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules attached to it.

The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and Nitrogenous bases.This is the structure of nucleotides and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another nucleotide molecule it forms a nucleic acid molecule.

The second structure from left to right with long carbon chains, it is a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.

However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced one of the the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.

The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids and hyrdogen atom.In the above structure condensation reaction has occurred between the hydrogen atom of the amine group and carbonyl group of the other amino unit to form a dipeptide.The bond formed from the condensation is the peptide bond.

The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO -Carbonyl group and hydroxyl group are glues to this.

goldenfox [79]

Answer:

c. Tubulin

Explanation:

Tubulin protein is polymerized to form the cylindrical structures of microtubules. Microtubules form the spindle apparatus during cell division. The spindle microtubules become attached to the kinetochores of chromosomes and mediate the alignment of chromosomes at the equator of cells during metaphase. The shortening of spindle microtubules is responsible for the movement of sister chromatids during anaphase. The same event also moves the homologous chromosomes during anaphase-I.

Any failure in the formation of the spindle apparatus would not allow the proper separation of chromosomes. Therefore, the cell with abnormal chromosome separation might have a faulty or no tubulin.
