how has limiting factors for the ecosystem impacted pythons in the everglades

Answers

Answer:

Explanation:

Non-native Burmese pythons have established a breeding population in South Florida and are one of the most concerning invasive species in Everglades National Park. Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe mammal declines in Everglades National Park have been linked to Burmese pythons.

The most severe declines in native species have occurred in the remote southernmost regions of Everglades National Park, where pythons have been established the longest. In a 2012 study, populations of raccoons had dropped 99.3 percent, opossums 98.9 percent, and bobcats 87.5 percent since 1997. Marsh rabbits, cottontail rabbits, and foxes effectively disappeared.

The mammals that have declined most significantly have been regularly found in the stomachs of Burmese Pythons removed from Everglades National Park and elsewhere in Florida. Raccoons and opossums often forage for food near the water’s edge, which is a habitat frequented by pythons in search of prey.

Statement C - spore

Statement D - prokaryote

Explanation:

The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.

Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.

Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.

An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.

(5) a) What is pathogen and write about different types of pathogens? b) Give name of the diseases of each pathogen. c) Do the pathogens enter directly into the body? How? d) What is incubation period?

Answers

Answer:

Microorganisms which causes diseases is known as pathogen.

Explanation:

PATHOGEN -: Pathogens are agents that live in a host and are responsible for causing infections or diseases in that host, such as a human being. Microorganisms such as bacteria , viruses , fungi or protozoa, or other organisms such as parasites, worms and even contagious proteins such as prions, may be pathogens.

Viruses: Viruses are micro-organisms that are composed of nucleic acid and covered by a protein sheet. A lipid (fatty) outer layer is also present in some viruses. Enveloped viruses are called these. Non-enveloped viruses are considered those that do not have this lipid outer layer. Only inside their host's living cells are viruses able to replicate. EXAMPLE -:  Influenza (influenza A and B viruses) and the common cold (rhinovirus) are examples of infections caused by viruses.

Bacteria: These are microorganisms which have a nucleus containing DNA surrounded by a cell wall or membrane. Among bacteria, the composition of the cell wall differs. If they are able to access food and nutrients, they have a more complex structure than viruses and can multiply beyond the host. EXAMPLE -: Foodborne diseases can be caused by bacteria such as Salmonella enterica and Escherichia coli, while Staphylococcus aureus can cause skin infections.

Fungi: Fungi are single-celled or multicelled species that can live outside a host. They consume food and nutrients created after digestive enzymes have been secreted into their atmosphere. example-: The foot of the athlete (Trichophyton mentagrophytes) and yeast infections (Candida albicans) are examples of infections caused by fungi.

Prions: These are infectious agents made up entirely of proteins and capable of transferring to other prion proteins their infectious properties. EXAMPLE -: Extreme infectious diseases such as bovine spongiform encephalopathy (mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD) can be caused by prions.

Protozoa: Protozoa are single-celled organisms that display habits that are similar to animals, such as the ability to travel through water, and are capable of harvesting other microorganisms. They are able to live outside the human host, but when they enter the human host and spread, causing infections and diseases, they may also be parasitic in nature. EXAMPLE -: Malaria and giardia include common infections

Yes , pathogen enter into the body directly -: Direct contact infections spread when, through direct physical contact with blood or body fluids, disease-causing microorganisms move from the infected person to the healthy person. Touching, kissing, sexual contact, contact with oral secretions, or contact with bodily lesions are examples of direct contact.INCUBATION PERIOD OF A PATHOGEN -:The period of incubation is the interval between exposure to a pathogenic organism, a drug, or radiation, and when the first signs and symptoms are evident.

Engineers tasked with building a car bumper need high-quality plastic that is readily available. They found the material polycarbonate, which is long-lasting and not too costly. Which is one technological design criterion they have already met? be available be attractive be durable be safe

Answers

Answer:

be durable

Explanation:

From the scenario described the Engineers have met one of the main criteria which is for it to be durable. A design needs to be made with a material that is available, durable, and cheap in order for it to be as efficient as possible while also selling and being profitable. By finding the material polycarbonate they have made sure that the design will be durable as well as cost-efficient since the material is "not too costly". Now if they are able to acquire the material in large quantities then they would have met the availability criteria as well.

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?

Answers

Answer:

Find the explanation below.

Explanation:

When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.

Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.

Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.

Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

Explanation:

What would occur if a nitrogen base in the RNA strand is mis-matched? How would that affect the protein? How could that affect the organism?

Answers

Answer:

Errors during Replication. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer.

In mismatch repair, mistakes that happen during DNA replication are recognized, cut out and replaced. ... This mismatched base pair causes a point mutation, which you can think of as a typo in the DNA sequence of the new strand.

Explanation:

Incorrectly paired nucleotides cause deformities in the secondary structure of the final DNA molecule. During mismatch repair, enzymes recognize and fix these deformities by removing the incorrectly paired nucleotide and replacing it with the correct nucleotide.

Eukaryotes have solved the end-replication problem by locating highly repeated DNA sequence at the end, or telomeres, of each linear chromosome. In humans and other vertebrate organisms, the sequence of nucleotides in telomeres is TTAGGG, is repeated between 100 and 1000 times.

Scientists have a theory about the relationship between climate and biodiversity. Which best describes this theory?

Warmer climates promote higher biodiversity, allowing plants to grow year-round. This supports more organisms that rely on plants.
Colder climates promote higher biodiversity, reducing the competition among organisms for food. This supports stronger organisms that live longer.
Warmer climates promote higher biodiversity because they tend to receive more rainfall. This provides a source of water for more organisms.
