In terms of structure and function how do the vacuoles in a typical plant cell compare to those of a typical animal cell
Answer:
Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.
The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.
What is the significance of the vacuole in plants and animals?Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.
Hence, the function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials

Which of the following statements is not true about heterotrophs?
Group of answer choices
Heterotrophs are classified as consumers.
Heterotrophs are at the base of most food webs.
Heterotrophs cannot make their own food.
Heterotrophs can consume autotrophs.
Heterotrophs are consumers, cannot make their own foods, and have some of them have the capacity to consume autotrophs. Hence, they are not at the base of most food webs.
Heterotrophs are organisms that have no capacity to manufacture their own foods, unlike autotrophs.
They depend on other organisms for their foods. Hence, they are known as consumers, unlike autotrophs that are called producers.
Heterotrophs are of different types:
Herbivores: those that consume autotrophs onlyCarnivores: those that consume meat onlyOmnivores: those that consume both autotrophs and meat.Thus, heterotrophs do not occupy the base of food webs. The base of food webs are mostly occupied by autotrophs, the producers.
More on heterotrophs can be found here: https://brainly.com/question/13420317?referrer=searchResults
Heterotrophs are at the base of most food webs is the statement that is false.
Heterotrophs are those that must consume organic matter from other living beings.Autotrophic beings represent the base in the totality of the trophic cycles or food chains, since they constitute the producing link, they are capable of taking advantage of energy and inorganic matter to make their food.Heterotrophs are characterized by not having the ability to produce their own food in their body, for this reason they need to consume the organic matter of other living beings.Therefore, we can conclude that autotrophs are considered producers and are at the base of most food webs, while heterotrophs are considered consumers which could not survive without feeding on other organisms.

What are some benefits of farming for the society/environment?
Answer:
Pasture and cropland occupy around 50 percent of the Earth's habitable land and provide habitat and food for a multitude of species. When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture. Farming creates more jobs, beginning with farmers, and continuing with farm equipment makers, food processing plants, transportation, infrastructure and manufacturing.
Explanation:
The benefits are:
early agriculture
Morden agriculture's opportunity
Development in farming sustainability
Farmers improve their communities

11 Apply If you have a cold that causes congestion in your sinuses, how
might that affect your sense of smell? Support your claim with evidence.
Answer:
If there's a blockage of this channel, like when you have a stuffy nose due to the flu or a cold, odors can't get to the sensory cells the smells stimulate. This results in you losing a lot of your ability to taste the flavor of food. In this manner, your senses of taste and smell work closely together.
Answer:
It will affect your smell because you can have a lot of snot in your nose and your nose will be stopped up with all that stuff.
You contract an infection from an unknown pathogenic organism. Your doctor conducts a biochemical analysis of the pathogen and discovers that it contains chitin. The pathogen is most likely a
Answer:
Fungus
Explanation:
Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!
Chitin is a natural polymer and a nitrogenous carbohydrate. The cell walls of fungus pathogens are formed of the N-acetylglucosamine polymer chitin.
What are pathogens?Pathogens are germs that enter, grow, and cause sickness in their host's body. It simply needs a host body to live.
Pathogens have the ability to circumvent the immune system. It likewise relies on body chemicals to survive. Depending on the kind, these bacteria can move from one host to another in a variety of ways.
What are fungus pathogens?The plant is home to millions of fungus species. Not all of them are pathogenic. Only roughly 300 of them are capable of causing disease. Fungi can be found on the surface of your skin or inside your food. They only cause illness if they overgrow.
Fungi have two protective layers, a membrane, and a cell wall, and they are difficult to destroy. The severity of a fungal infection might vary.
What are the examples of fungus?Ringworm.Vaginal yeast infection.Jock itch. Other fungiThus, we can conclude that the unknown pathogenic organism is fungus because fungus pathogens contain chitin.
