Mating Behavior

Mating behavior is the actions between mutually attracted individuals of the opposite sex. Male peacocks  spread their colorful tail feathers, like the ones pictured here, to attract female peacocks.

Homologous Structures

Homologous structures are body parts that are alike because, according to the theory of evolution, the species in question share a common ancestor. For example, the human ear ossicle is similar to the fish jaw bone.  This is a picture of salmon to represent the fish jaw bone.

K-Strategist

K-strategists are organisms that produce small numbers of offspring at a time and protect their young. Dogs, like my friend’s dog,  are K-strategists

Introduced Species

Introduced species are species that humans have placed into an ecosystem or community, accidentally or intentionally, in which it doesn’t naturally occur. This is a picture of a  tree in my neighborhood which was planted there by the homeowners association.

Heterotroph

A heterotroph is an organism that derives its nutritional requirements from complex organic substances. All animals such as my friend’s other dog are heterotrophs.

Glycogen

Glycogen is a substance deposited in body tissues as a store of carbs. Glycogen is found in human muscles, like the ones demonstrated by my little brother  in the picture.

Frond

A frond is the leaf or leaflike part of a palm or fern. This is a picture of a fake palm tree. The green leaflike parts are its fronds.

Epithelial Tissue

Epithelial tissue is the membraneous tissue covering internal organs and other internal surfaces of the body. This is a picture of my little brother’s leg which is covered in this tissue.

Endotherm

An endotherm is an organism that generates heat to maintain its body temperature. All mammals, such as cats, are endotherms.

Cellular Respiration

Cellular respiration is the metabolic process in which certain organisms obtain energy from organic molecules. Plants such as this flower go through cellular respiration.

Autotroph

An autotroph, or producer, is an organism that produces complex organic compounds from simple inorganic molecules using energy from the photosynthesis or chemosynthesis. This is a picture of an evergreen tree which is an example of an autotroph.

Bilateral Symmetry

Leaves have bilateral symmetry which means that they have a basic body plan in which their left and right sides can be divided congruently.

Pollen

This is a bee. Bees travel from flower to flower spreading pollen, which is a powdery substance produced by the anthers that fertilizes the flowers.

Asexual Reproduction

This is a fake flower from my room. Real flowers  reproduce asexually, which means that one individual produces offspring that are genetically identical to itself.

Animal that has a segmented body

This is an ant which I found in my kitchen. An ant has a segmented body, which is a body divided into segments that are often grouped into larger functional units. The ant is in the lower right corner of this picture on the white tile.

The Hot Zone Part 4

1 Comment

The last part of the hot zone was quite different from the rest of the book. It is about how the author went to Kitum Cave himself to check things out. I wasn’t expecting him to go and don’t really understand why he went since he wasn’t looking for the viruses. i guess its nice to go explore nature like that but i thought it was strange that he knew he was risking his life to explore the cave. it was interesting to learn about how kitum cave was carved by elephants. i never knew they went into caves to obtain salt.The ending kind of leaves you hanging because even though the filo viruses are out of sight in the U.S. we know that it is still hiding somewhere in the african rainforest. also, no cure was developed whatsoever and the source of the virus remains a mystery.

Adaptation of an animal

An animal adaptation is a change over generations that allows a species to better survive in its habitat. This is a picture of a chipmunk hole. Chipmunks hibernate in these holes, which is an adaptation that helps chipmunks live through the freezing winters.

 

C3 Plant

A C3 plant is a plant that produces the 3-carbon compound phosphoglyceric acid as the first stage of photosynthesis. This is a picture of a potato which grows on a C3 plant.

Adaptation of a Plant

A plant adaptation  allows a plant to live in a certain place. This is a picture of leaves that changed color and fell off a deciduous tree. These trees save energy by losing their leaves in the fall which helps them better survive the winter.

C4 Plant

C4 plants are plants that produce the 4-carbon compound oxalocethanoic acid as the first stage of photosynthesis. This crabgrass is an example of a C4 plant.

Anther and filament of stamen

A stamen is the male organ of a flower that consists of a filament, which is the stalk of the stamen, and an anther, which bears pollen. This is a stamen.

Lichen

 A lichen is a simple plant consisting of a fungus, usually of the subdivision Ascomycotina, that grows symbiotically with algae. It usually forms a low crust-like or branching growth on rocks, walls, or trees. This is a picture of lichen growing on a tree.

ATP

 ATP, short for adenosine triphosphate, is a nucleotide that occurs in the muscle tissue of animals and the mitochondria and chloroplasts of plants and is used as a source for cellular reactions. This is a hydrangea plant that contains ATPs in its cells.

 

Enzyme

An enzyme is a substance, such as proteins, produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Chicken is an example of a protein.

 

Endosperm

 The endosperm is the nutritive tissue within seeds of flowering plants. The endosperm surrounds and is absorbed by the embryo. Coconut water is an example of endosperm and is found in coconuts. 

Cambrium

  Cambrium is a cellular tissue found in all plants in which phloem, xylem, or cork grows by division. In woody plants, this results in secondary thickening. Cambrium is found in this hydrangea plant.

The Hot Zone Part 3

THis book gets more suspenseful with every part. I just got finished with the reading and still have lots of unanswered questions. It seems like the scientists involved with the monkey experiments sti have a lot to figure out about the viruses. The massacre of the monkeys continued in this part as 4oo more expirimental monkeys had to be killed. I have mixed feelings about this because while animal testing is unsettling to me one has to remember the pros involved since it aids in research for human survival. As far as the Jaax family, i thought that it was a little extreme that nancy didnt see her dying father for the last time and stayed to expiriment with the monkeys instead. I also thought it was funny how Jerry ended up in a space suit himself after all. The monkey insides gross me out, but other than that i am enjoying this book.

 

 

 

Week 5 Scavenger Hunt

Gibberellins

Gibberellin are plant hormones that regulate growth and influence various stages of the developmental process. Gibberellin are found in young leaves like the ones pictured here.

Meristem

Meristem is the undifferentiated tissue from which new cells are formed at the tip or root. This tree has meristem in its roots.

Lipid used for energy storage

Lipid is a fatty or waxy organic compound that is readily soluble in non-polar solutions. Oil, such as the olive oil in my kitchen, is a lipid used for energy storage in animals.

Long-day plant

A long-day plant is a plant that flowers only after being exposed to light in periods longer than a certain critical length, like in the summer. Lettuce is an example of a long-day plant.

Flower Ovary

A flower ovary is an ovule-bearing lower part of a pistil.  In the bottom middle of the blossom is the flower’s ovary.

Fermentation

 Fermentation is the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat. Fermentation takes place in the production of cheese when lactic acid is produced and acts with an added enzyme.

Exoskeleton

 An exoskeleton is a rigid external covering for the body in some invertebrate animals. Crustaceans, like the one that once lived in this conch shell, have exoskeletons. 

Eubacteria

 Eubacteria are a type of bacterium that have simple cells with rigid cell walls and often flagella for movement. Some eubacteria can cause diseases that can supposedly be killed by this hand sanitizer.

Connective Tissue

Connective tissue is a kind of tissue that binds, connects, supports, or separates other tissues or organs. The inner layers of the skin and bone and fat tissue are examples of connective tissue and are components of my hand.

Cuticle Layer of a Plant

 The cuticle layer of a plant is the non-cellular protective layer covering the outer cell layer of the green aeriel parts of land plants. This is a picture of a flower that has a cuticle layer on it.

The Hot Zone Part 2

The second part of the Hot Zone delves into an even more interesting plot. The section is set around the monkey house in Reston, Virginia where scientists have trapped several monkey in different rooms and are using them for research for the hot viruses. It is interesting to learn about the different monkeys and their behaviors such as the crab eating monkeys who dislike humans (I never knew that there were crab eating monkeys!). However, I dreaded reading the parts about when the monkeys were cut open and examined. I have been forced to face the fact that this book will continue to be more gross and gruesome than my liking. I was also shocked at the murder of Jerry Jaax’s brother and the fact that Nancy continues to dissict monkeys rather than visit her dying father. The end of Part two becomes more suspenseful as the scientists at the monkey house race to find answers.

Sorry about posting this two days late but we’ve been traveling on the road for the past two days and we just got home late yesterday night, so that is why I was unable to post on time.

CAM Plant

 CAM plants go through a type of photosynthesis in which CO2 is taken up and stored during the night to allow the stomata to remain closed during the day which decreases water loss.

Biological Magnification

 Biological magnification is when substances such as fertilizers or other pollutants get into the water of a lake or other body of water and are eaten by fish. The fish are then eaten by birds or humans. The substances become absorbed into the inner tissues and organs of the organisms which can harm them.

Auxin producing area of a plant

 Auxin is a plant hormone that causes the elongation of cells in shoots and is involved in regulating plant growth. The tomato plant makes its auxin in its shoot apical membrane and the auxin travels downward in the phloem.

Calvin Cycle

 The Calvin cycle is a metabolic pathway found in the stroma of the chloroplast in which carbon enters in the form of CO2 and leaves in the form of sugar.

Ectotherm

 An ectotherm is an organism that regulates its body temperature with its surroundings.

Yay, I was finally able to post on the blog with the help of Sophia! 🙂
