The Hot Zone Post Part 4

1 Comment

Part 4 of The Hot Zone was a very appropriate conclusion to this thrilling novel.  I was glad to see the author decided to take the risk and travel to Kitum Cave himself to better understand the mystery and danger surrounding the cave.  It was also fitting for the author to revisit the monkey house and see what was left of it.  Preston’s description of the desolate monkey house was very eerie to me.  Again I appreciated Preston’s vivid details about his travels to Mount Elgon and the deserted monkey house.  However, I feel he ended the novel with a lot of unanswered questions.  Such as what became of the characters who dealt with Ebola Reston.  Also I find it hard to believe that no one in the world has been able to find a cure for these deadly viruses.  All in all, this was a very well written novel with a good plot, and the last line saying, “It will be back” sent chills down my spine.

This cactus is an example of an adaptation of a plant because it has developed needles in order to survive and keep away predators.

Analogous structures are organs or traits that are similar to other organisms, but do not perform the same functions. A human’s arm isn’t used for walking but a dog’s arm is.

The inner area of a tree is the phloem. Phloem is the living tissue in vascular plants responsible for carrying organic nutrients to all the parts of the plant where they are needed.

Birds are a good example of K-strategist because they mainly reproduce in small numbers and focus on protecting their offspring so they have a longer life span. K-strategists also have a lower mortality rate.

Butterflies like many other organisms have bilateral symmetry, which is a basic body plan where the left and right sides of the organism mirror each other.

Ectoderms are organisms that control their body temperature through external means, such as fish, which rely on environmental heat sources.

Ginger is a rhizome which is a horizontal, underground plant stem is capable of producing the shoot and root systems of a new plant through asexual reproduction.

These two mice are exhibiting mating behavior and are attempting to produce more offspring.

C3 plants tend to grow in cloudy, cool, and wet climates where the light levels are often low, and they contain 3 carbon atoms.

The thorns on this rose bush are an example of a modified stem of a plant because the thorns offer protection for the plant.

Epithelial tissue covers the entire human body and also lines the organs. It consists of cells closely packed together and arranged in multiple layers.

This seed came off of a tree and is an example of seed dispersal by the means of wind to knock the seeds off of the tree and spread them around.

This is the neighbor’s dog which exhibited territorial behavior by barking and growling at me when I attempted to come into its backyard, or territory.

Commensalism is a symbiotic relationship where one species is unharmed and the other species receives benefit from the relationship. I am giving my dog a treat which benefits her and is not harming me.

The best known xylem tissue is wood as shown in the picture. Xylem tissue is found throughout the plant and its basic functions are to transport some nutrients and water through the plant.

Connective tissue is one of the four traditional classes of tissues and it is a fibrous tissue. Connective tissue can be found throughout the body.

Eubacteria is commonly found in yogurt. Eubacteria turns milk into yogurt after the process of fermentation has occurred.

This plant is exhibiting tropism because it is attempting to grow out of the shade and into the sun. Tropism is the growth or movement of a plant towards or away from an external stimulus.

These weeds are r-strategists because they produce many offspring, have a short life-span, and disperse their offspring widely.

This ant pile represents a population. The ants live together and work together in order to gather food, build a shelter, and survive.

This corn starch is an example of glycogen because glycogen is a molecule that can be put with other glycogen to make starch

These hermit crabs would be considered littoral zone organisms because their natural habitat is where the land and sea meet between the high water and low water marks.

Gymnosperms are a group of vascular plants whose seeds are not enclosed by an ovary. A pinecone is a gymnosperm cone.

A unicellular organism contains only one cell. An example of a unicellular organism is yeast, which is commonly found in bread.

Apples produce ethylene. Ethylene is a plant hormone involved in promoting growth and also contributes to other various plant functions.

Part Three of The Hot Zone has really summed up the intense Ebola virus situation in Reston.  It was a relief to finally found out the Ebola Reston strain was not harmful to humans, but it is also scary to think that a virus which is so deadly has the potential to spread through the air.  It was very intriguing to find out just how much planning and precautions were taken by the Army to ensure the Ebola strain was eradicated from the Reston monkey house.  It must have been extremely hard on the Army veterinarians to have to euthanize such a large about of monkeys.  Another surprising fact was that the army used relatively young and inexperienced soldiers to perform such a delicate operation.  I also can not believe that the Ebola scare in Reston did not receive more media attention, I would have thought a crisis such as this would be all over the news and internet.  Instead there was relatively small media exposure.  I personally find it frightening that the sick workers in the monkey house have Ebola Reston strain in their bodies.  I am looking forward to reading part four and seeing how this exhilarating novel ends.

This turtle has an exoskeleton. An exoskeleton supports and protects an animal from the outside such as a turtle’s shell.

This cactus is an example of a modified leaf of a plant. The spines of this cactus have adapted to protect the cactus and also to save water.

An organism that reproduces asexually is able to produce offspring without a mate, such as a strawberry plant. The offspring is a clone of the parent, and this results in minimal genetic variation in the species.

These worms are detritovores because they feed on organic waste and dead organic matter.

The vegetative part of this mushroom is the mycelium that consists of a mass of branching hyphae.

Butter is a common lipid that is used for energy storage and it contains both unsaturated and saturated fatty acids. Lipids are a necessary structural component of living cells.

There is lichen growing on this rock. Lichen is the combined growing condition of algae and fungus and is usually found in terrestrial habitats.

Wine is an example of fermentation. Fermentation is the anaerobic cellular process where organic foods are transformed into less complex compounds and ATP is produced.

This leaf is a gymnosperm leaf because the seeds are located in the pods of the leaf instead of being inside the ovary of the plant.

An endotherm is an organism that produces its own heat through internal means such as shivering or increasing its metabolism. My friend’s cat would be an example of an endotherm.
