Answer:
Bioindicators
Explanation:
Answer:
Indicator species and/or keystone species
Explanation:
Indicator species are species (e.g., plants, animals, fungi) that can be utilized to determine changes in the environment. An indicator species can show the impact of pollution on an ecosystem. For example, mosses are indicator species that indicate the acidity in the soil. Moreover, keystone species are species that maintain the ecological balance in the ecosystem. When a keystone species is removed, the entire ecosystem is dramatically changed or may even cease to exist altogether. In consequence, keystone species can be used to define an entire ecosystem. For example, bees are a keynote species that contributes to balance the ecosystem by pollinating plants.

Which of the following is a accurate depiction of primary ecological succession?
Answer:
This question lacks options, however, primary succession will be explained for detailed comprehension.
Explanation:
Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.
Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.

How does genotypic variation occur?
Answer:
Genotypic variation occurs when alleles are randomly sorted during sexual reproduction. ... Some types of organisms can increase genetic variation through reproduction. They are able to combine the genetic material of two parents, rather than copying the genetic material of a single parent.

An ecosystem has been interrupted by an invasive species. A new grass eating lizard lives in the same ecosystem as a grass eating rabbit. Hawks eat both lizards and rabbits. What would happen to the grass and hawk populations immediately? Why?
There would be more hawks appearing because there is more food (both lizards and rabbits) and grass would lessen because there is another source feeding off of it.
I hope this helped ^^
Answer:
the grass population would decrease and hawk population would increase

Prevention of Foodborne Illness
Food purchased from the grocery store may contain pathogens that cause foodborne illness. To reduce the risk of illness, follow proper procedures for food preparation and storage.
Drag the appropriate items into their respective bins.
1- Divide large pots of soup into smaller batches before cooling.
2- Use a food thermometer to make sure meat has reached an appropriate internal temperature.
3- Thoroughly wash cutting boards used for cutting raw meat before slicing fresh vegetables on them.
4- Do not use color as an indicator of how well-cooked meat is.
5- Wash hands correctly before and after handling food.
6- Refrigerate leftover food within 2 hours.
7- Thaw meat on the bottom shelf of the refrigerator.
8- Wash fresh fruits and vegetables before preparing and/or eating.
Clean Combat Cross-Contamination Cook Chill
Answer:
1- Chill
2- Cook
3- Combat Cross-Contamination
4- Cook
5- Clean
6- Chill
7- Combat Cross-Contamination
8- Clean
Explanation:
A foodborne illness (also known as food poisoning) is an illness caused by eating contaminated foods by harmful microorganisms such as bacteria (e.g., Escherichia coli), viruses, parasites, and/or toxins (e.g., mycotoxins) contained in foods. Some of the most common symptoms of food poisoning include vomiting, nausea and diarrhea. Foodborne illnesses are generally caused by improper practices in the home kitchen, i.e., improper handling, preparation and food storage. Cross-contamination refers to the transfer of harmful microorganisms/toxins from one substance to another. The most common contributing factors to cross-contamination include equipment-to-food contamination, food-to-food contamination, and people-to-food contamination. The most important habit to prevent cross-contamination is washing hands and foods before eating and cooking. Moreover, cooking foods to proper temperatures can destroy microorganisms/toxins that cause foodborne illnesses. Finally, chilling (at 8˚C or below) and freezing (at -18° C) foods can also protect from food-borne illnesses as many harmful microorganisms cannot grow at these temperatures.

what are the different ways fungal spores can be dispersed?
Answer:
Explanation:
The spores of some fungi are dispersed in water or on the surface of water. The chemical composition of the wall of these spores makes them "non-wettable" so they won't sink. The spores are carried along on the surface of the water like little boats. Water in the form of raindrops can disperse spores in a different way. While gravity is not a primary means of spore dispersal, evolutionary adaptations have been required of many fungi to overcome gravitational effects for effective spore dispersal. SPORE DISPERSAL BY WIND Dispersal of fungal spores by wind is by far the most common method for terrestrial fungi.
