Evolution Assignment 1

In the picture are four different types of finches that came from the same ancestor. Darwin found finches on the Galapagos islands that were almost identical to finches on the mainland. They just had different types of beaks that have evolved to adapt to their environment and the food they have to eat. Some birds have large sturdy beaks while others have a small beak, and others have a special curved beak. The island was so far away from other land so, the birds could not fly to other islands. So that leads to when there is not a enough food source for one certain bird they can die off and the remain will reproduce with the stronger breed that year and their offspring will have the characteristics to adapt and survive in their environment. The birds with large beaks can eat large and hard sized seeds, berries, and nuts while the small beaked bird can eat soft small seeds. The bird with the curved beak can eat insects and seeds.

Prokaryotes, Protists, or Fungi Assignment 2

Aspergillus flavus is a fungus that can inhabit the soil. When it inhabits the soil it can have an effect on crops and livestock. Aspergillus flavus in the soil are saprophytes which live on decaying matter. The most common crops flavus affects is oil seed containing crops for an example as cottonseed. Aspergillus flavus can also be found in medicine. Even though it can be found in medicines it can still cause diseases and infections in humans. It produces a toxic compound called aflatoxins. If food or feeds consumed with aflatoxins can cause toxicity and long term illness. The top sickness Aspergillus flavus causes is sinusitis and keratitis.

Monocot vs Dicot plants Assignment 3

amoon6 — 2025-02-03 16:35:30 UTC

In the picture are two different groups of flowering plants and what characteristics determine which group plants go into. In monocot plants they have one seed and dicot has two. A stem on monocots are green and have scatted vascular bundles while dicots stems are normally woody. An example of a monocot plant I see everyday is a banana plant. They have one seed which the leaves form from and their big leaves have parallel veins. Their stems are also not woody. In the spring and summer many Dicot flowers start blooming. One example is roses they have a tap root system and their flowers part four or five. Their stems are also woody. Also as seen in the picture coffee beans can be grouped as dicots because they have two seeds.

Enchinodermata Assignment 4

Echinoderms are sea stars, Sea cucumbers ,sea urchins and many more. All echinoderms live in the ocean everywhere. Most of the time they can be found on the ocean floor. All our radial symmetry which means it has a center point in which it grows from. This can be harder to see on Sea cucumbers and urchins. They also have 5 arms or 5 rows of arms. There are a few sea stars that grow more than five arms or if they lose an arm it can grow two back in the place of one. Echinoderms also have tubed feet that they can fill with salt water. These tubes have muscles in them and can be used to help move. Fossils have shown they have been here for 500 million years.

Homeostasis in humans Assignment 5

Homeostasis is a system the human body uses to maintain a steady state. Cells, tissues, and organ systems help this process. Your body is constantly making adjustments to help keep a maintained internal environment stable. There are four components that help the process of homeostasis. These four components are stimulus, sensor, control center, and effector. Your body has a set point for body temperature and blood sugar. Normal body temperature is 98.6. Homeostasis is used to help keep your temperature and blood sugar in normal ranges. Sometimes homeostasis can fail and if it does it results in homeostaic imbalance. This results in cells not getting what they need or toxic waste not being removed. If the process of homeostasis does not work it can result in disease or even death. Diabetes is an example of a disease caused by the process of homeostasis failing.

Celiac Disease Assignment 6

Celiac disease is a disease that bothers the digestive system. The ingestion of gluten is what causes celiac disease. This can cause symptoms like diarrhea and nutrient deficiency like iron deficiency and D3. The only way to manage it is to have a gluten free diet. A well balanced gluten free diet will consist of fruits, nuts, vegetables, gluten free whole grain cereal. Women are more affected by it than men. Iron deficiency is common if celiac disease is left untreated meaning not having a gluten free diet. Nowadays if you have low iron you will be tested for celiac disease.

Arctic tundra Assignment 7

amoon6 — 2025-02-27 20:49:18 UTC

In the picture there is a polar bear walking in the snow with a mountain behind them. The arctic tundra has high mountain tops. It also has extremely cold winters and not long summers. Since it has an extremely cold winter and the precipitation is usually snow. There are a few plants that grow in the arctic regions since the snow and cold. In the picture you cannot see any plants due to the snow on the ground. The animals that adapt to live in Arctic regions are polar bears, arctic foxes, and birds that migrate. This means the Arctic tundra as a low biodiversity because of the cold climate and hash conditions.

Biodiversity Assignment 8

Biodiversity is important in science when talking about living things in their environment. Bio is a greek term that means life and diversity means variety. So biodiversity means all the different kinds of organisms that live in that environment. There are several facts that help that depend on how many organisms live in an environment. Those facts are how water and sunlight access the organism has, the temperature, and shelter. The tropical rain Forrest has a high biodiversity because of all the organisms that live there because of the weather and shelter the trees provide. While the antarctic tundra has a very low biodiversity because of the extremely cold weather and few organisms can live there. Biodiversity is important to help keep a thriving planet and ecosystems.
