how are detritivores different from decomposers? provide an example of each
Decomposers return nutrients to the ecosystem, while detrivores consume dead things. Bacteria and fungi are examples of decomposers, and vultures are examples of detritivores.
What is detritivores?Detritivores are heterotrophs that get their nutrients from detritus. Coprophagy is practiced by a wide range of invertebrates, vertebrates, and plants.
Detritivores, such as millipedes, earthworms, and termites, eat dead organisms and wastes while decomposers break down dead organic materials.
Detritivores are distinct from other decomposers in that they consume material in order to decompose it. Bacteria and fungi, for example, do not eat their food; instead, they decompose it externally.
Decomposers replenish the ecosystem's nutrients, whereas detrivores consume dead things. Decomposers include bacteria and fungi, while detritivores include vultures.
Detritivores feed on detritus particles, whereas decomposers "feed" by chemically breaking down organic matter.
Thus, detritivores are different from decomposers.

What is the primary storage form of carbohydrate in the body?
a. glucagon
b. glucose
c. starch
d. fiber
e. glycogen?
Glycogen is the primary storage form of carbohydrates in the body, stored in liver and muscle cells, and is broken down into glucose when needed.
Explanation:The primary storage form of carbohydrate in the body is e. glycogen. Glycogen is made up of glucose monomers and is a highly branched molecule, usually stored in liver and muscle cells. Glycogen functions as the animal equivalent of starch. When the blood glucose levels decrease, the body breaks down glycogen into glucose in a process called glycogenolysis, maintaining the homeostasis of glucose levels in the bloodstream.

A patient is admitted to the hospital for dehydration and malnutrition. on close observation of the intestine, it appears that the cells lining the intestine have fully formed microvilli. however, these microvilli are not uniformly standing upright and protruding into the lumen of the intestine, but are lying down so that full exposure to the contents of the intestine cannot be obtained. the doctors conclude that the patient may have a defect in what cellular component? microfibers actin myosin tubulin intermediate filaments
The patient's microvilli lying down instead of standing upright indicate a possible defect in the actin microfilaments. These microfilaments provide structural integrity to the microvilli, which are crucial for nutrient absorption in the intestines.
The doctors conclude that the patient may have a defect in the cellular component known as actin microfilaments. These microfilaments are responsible for maintaining the structure and shape of the microvilli. In the intestine, microvilli constitute part of the cell's plasma membrane and function to increase surface area for efficient nutrient absorption. When microvilli "lie down" instead of protruding into the intestinal lumen, it suggests that the structural integrity of the microvilli is compromised, most likely due to a problem with the actin microfilaments that form the core of each microvillus. Adequate maintenance of these microfilaments is essential for the proper absorption of nutrients, which can be impaired in conditions such as celiac disease.
Therefore, the presence of deformities in the actin microfilament structure can be linked to illnesses resulting in malnutrition and dehydration, as observed in the patient.

What is the smallest lithostratigraphic rock unit? formation bed layer group
Answer: Option (1)
Explanation:
The basic lithostratigraphic unit of rock is formation. A formation is comprised of definite rock body whose rock characteristics can be compared to another rock strata, and can be mapped easily.
A bed is defined as the distinctive rock layer that can be differentiate from its upper layer and the lower layer, and are usually more than 1 cm in thickness.
A layer is defined as a distinct rock body, which has a particular rock materials and are distinguishable from one type to another and they are precisely traceable.
A group of rock is comprised of different rock units or layers, forming a division of the geological rock history.
Thus, the correct answer is option (1).
Which process brings energy to the biosphere?
The ion needed to initiate the release of acetylcholine into the synaptic cleft is
The ion needed to initiate the release of acetylcholine into the synaptic cleft is the calcium ions.
What is a Synaptic cleft?A synaptic cleft may be defined as the type of tiny space after the axon terminal of the pre-synaptic neuron and initiation of the cell body or dendrites of the postsynaptic neuron. It is also known as the synaptic gap.
When the presynaptic membrane of an axon terminal is depolarized, it induces the opening of voltage-gated calcium ion channels. It allows the influx of calcium ions inside the cell.
This entry of calcium ions induces the fusion of synaptic vesicles with the membrane and finally the liberation of neurotransmitters such as acetylcholine molecules into the empty space which is known as the synaptic cleft.
Therefore, calcium ions are needed in order to initiate the release of acetylcholine into the synaptic cleft.

the cells of unicellular organisms are A.) specialized to perform specific tasks B.) larger than those of multicellular organisms C.) able to carry out all of the functions necessary for life D.) unable to respond to changes in the environment
The cells of unicellular organisms are capable of performing all of life's essential functions and responding to their environment. Unlike multicellular organisms where cells are specialized for specific tasks, each unicellular organism carries out all functions within a single cell. However, multicellular organisms offer higher levels of organization and complexity.
Explanation:The cells of unicellular organisms, such as bacteria, can carry out all the functions necessary for life. Unlike the cells of multicellular organisms which are specialized, each cell of a unicellular organism can perform tasks essential for its survival, such as converting the energy in sugar molecules into energy in ATP. At the same time, these cells can also respond to their environment by turning on and off specific genes according to the demands of their surroundings.
Despite this adaptability, unicellular organisms do not have the level of complexity or organization seen in multicellular organisms. Organisms composed of multiple cells can coordinate between distantly located cells and have developed systems such as a circulatory system or an efficient respiratory system to bring nutrients and oxygen to their cells respectively. Furthermore, these cells become more efficient by becoming specialized, doing fewer tasks but doing them extremely well.

Why is sandstone considered a rock and NOT a mineral? What characteristics of a mineral does it not meet? Answer in at least 2 sentences
Final answer:
Sandstone is a rock because it lacks a consistent crystal structure and is made up of various minerals and particles, unlike a mineral which must have a unique crystalline structure and a specific chemical formula.
Explanation:
Sandstone is considered a rock and not a mineral because it does not have a consistent internal crystal structure and is not composed of a single substance. A mineral, by definition, is a naturally occurring, inorganic solid with a specific chemical formula and a unique crystalline structure. Sandstone fails to meet these criteria because it is a clastic sedimentary rock composed of sand-sized particles that can include a variety of minerals like quartz and feldspar, as well as rock fragments or organic material. Different parts of sandstone may have different compositions, making it heterogeneous. Furthermore, sandstone is often found in layers or beds, can be granular or gritty, and displays physical characteristics like color variation and potentially containing fossils, which are not features specific to minerals.
