It is known that complex carbohydrates provide more sustained energy over time than simple sugars such as sucrose. Complex carbohydrates are polysaccharides, which are long chains of smaller sugar molecules bonded together. Simple sugars are monosaccharides that contain only one molecule.
Why do complex carbohydrates provide more energy over time versus simple carbohydrates?
Answer:
Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy. As complex carbohydrates have longer chains, they take longer to break down and provide more lasting energy in the body than simple carbohydrates
Explanation:
Answer:
A.) Complex carbohydrates have more chemical bonds to break than simple sugars, which takes longer for the body to digest and provides more units of energy for the body to use.

Explanation:
Humans deplete the most resources when
Answer:
Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.
Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.

Which theory is represented in this diagram?
The theory that complex cells evolved after primitive cells engulfed bacterial cells that continued functioning
The theory that all living organisms share the same basic genetic components
The theory that organisms function best when their internal conditions are maintained within narrow limits
The theory that all living organisms are made of cells
The correct answer is A. The theory that complex cells evolved after primitive cells engulfed bacterial cells that continued functioning.
Explanation:
This diagram shows how a primitive cell or a cell containing only genetic material evolves into a complex cell with specific organelles such as chloroplast or mitochondria by engulfing or integrating other cells, especially prokaryotic cells that continue living in the primitive cell and become specialized organelles. This process supports the theory the evolution of cells was possible as simple cells engulfed bacteria because as the diagram shows the engulfed bacteria evolved into organelles that make the cell become more complex as there were specific structures in the cell for different functions.

Explanation:
The innate immune response is the first mechanism for host defense found in all multicellular organisms. The innate immune system is more ancient than the acquired or adaptive immune response, and it has developed and evolved to protect the host from the surrounding environment in which a variety of toxins and infectious agents including bacteria, fungi, viruses and parasites are found (1).
The immune system is complex and is divided in two categories: i) the innate or nonspecific immunity, which consists of the activation and participation of preexistent mechanisms including the natural barriers (skin and mucosa) and secretions; and ii) the adaptive or specific immunity, which is targeted against a previously recognized specific microorganism or antigen. Thus, when a given pathogen is new to the host, it is initially recognized by the innate immune system and then the adaptive immune response is activated (2). Innate immunity is the host’s first line of defense and is intended to prevent infection and attack the invading pathogens.This nonspecific mechanism is fast (minutes to hours) while the adaptive response takes longer (days to weeks).
Innate immunity is comprised of different components including physical barriers (tight junctions in the skin, epithelial and mucous membrane surfaces, mucus itself); anatomical barriers; epithelial and phagocytic cell enzymes (i.e., lysozyme), phagocytes (i.e., neutrophils, monocytes, macrophages), inflammation-related serum proteins (e.g., complement, C-reactive protein, lectins such as mannose-binding lectin, and ficolins); surface and phagocyte granule antimicrobial peptides (e.g., defensins, cathelicidin, etc.); cell receptors that sense microorganisms and signal a defensive response (e.g., Toll-like receptors); and cells that release cytokines and inflammatory mediators (i.e., macrophages, mast cells, natural-killer cells). Once the interaction host-invader pathogen enters, a signaling cascade is initiated which enhances the immune response and activates specific mechanisms (3-5). This natural immune response is designed to: a) prevent infection, b) eliminate invader pathogens, and c) stimulate the acquired immune response.
The correct examples of physical, chemical, and biological barriers are coughing, saliva, and complement system respectively.
What do you mean by Barriers?Barriers may be defined as something that blocks the free passage of any object, compound, or thing.
Coughing mediates the physical barrier that kills the pathogen and improves the body's immune system at the physical level. Saliva consists of an enzyme that kills the pathogens on body surfaces, so it is classified under a chemical barrier. Biological barriers involve the action of the complement system which performs the activity of lysis of pathogen particle and stimulate the body's immune response.
Therefore, the correct examples of physical, chemical, and biological barriers are coughing, saliva, and complement system respectively.

Imagine we have labeled tetrodotoxin (TTX) so that it can be seen with a microscope. If we wash this TTX onto a neuron, what parts of the cell would you expect to be labeled?
A. Axons
B. Mitochondria
C. Dendrites
D. Cell bodies
Answer:
C
I just didnt do it
Explanation:
Axon is the part of the nerve cell which would be expected to be labelled which can be seen by washing TTX onto a neuron. Thus, the correct option is A.
What is Tetrodotoxin (TTX)?
Tetrodotoxin (TTX) is a natural toxin which interferes with the function of voltage-gated sodium channels in the cell membrane. Tetrodotoxin blocks the sodium permeable pore in the membrane by binding tightly to a specific part outside the channel proteins and block all the sodium-dependent action potentials in the membrane.
Applying TTX to a neuron would block all the impulses in the neuron, preventing it from firing action potential, regardless of the impulse. Labeled TTX could be visualized on the cell's axon, where the voltage-gated sodium channels are concentrated.
Therefore, the correct option is A.

What are the steps in the scientific process to test whether plants need water to survive?
Answer:
Please find the detailedly explained steps below
Explanation:
Scientific investigation involves the use of the SCIENTIFIC METHOD, which involves series of steps including:
- Making an observation/Asking a question
- Formulating a hypothesis
- Testing the hypothesis
- Analysing the result
- Conclusion
1) Making an observation/Asking a question: An observation is initially made prior to any investigation. In this case, the observation is whether plants need water to survive. A scientific question can be asked by saying DO PLANTS NEED WATER TO SURVIVE?
2) Formulating a hypothesis: After a question has been asked or an observation has been made, a HYPOTHESIS, which is a testable explanation given to solve or answer the problem is given. A hypothesis is usually in an IF, THEN format. A hypothesis concerning the observation can go thus: IF plants are not supplied with water, THEN they will not grow.
3) Testing the hypothesis: In order to test the hypothesis, an experiment is conducted. This experiment is set up in such a way that two group of plants are used. One group receives water (experimental group) while the other doesn't receive water (control group). The water is the INDEPENDENT VARIABLE while the plant growth measured is the DEPENDENT VARIABLE.
4) Analysing the result: The results of the experiment are analysed and computed in an organized way that can be comprehended.
5) Conclusion: This is the point where the hypothesis will be accepted or rejected based on the results of the experiment. For example, in this case, if plants that are not supplied with water grows, the hypothesis will be REJECTED.

If you followed a woman's cells through meiosis, at what stage of meiosis would the amount of DNA in one of these cells be equal to the amount of DNA in one of her G1 phase (before DNA replication) kidney cells
Answer:
at the end of the meiosis I
Explanation:
At the end of meiosis I, the resulting number of chromosomes is equal to the number of chromosomes as the original diploid (2n) parent cell. Moreover, at the final of meiosis II, each daughter cell will have half of the number of chromosomes as the original parent cell, i.e., a haploid (n) number of chromosomes. All the somatic cells have a diploid number of chromosomes, while gametic cells have a haploid number of chromosomes. Kidney cells are somatic cells. In humans, each diploid cell contains 46 chromosomes (i.e. 23 pairs of chromosomes), while gametic cells (i.e., egg and spermatic cells) have 23 chromosomes. In consequence, in humans, kidney somatic cells and cells at the final of the meiosis I will have the same number of chromosomes (i.e., 46 chromosomes).

how is the classification of living things related to the structure of their cells?
Answer:
The most basic classification of living things is kingdoms. ... Living things are placed into certain kingdoms based on how they obtain their food, the types of cells that make up their body, and the number of cells they contain. Phylum. The phylum is the next level following kingdom in the classification of living things.
Explanation:
hope these help
The classification of living things significantly depends on the structure of their cells and based on this, they are divided into two types. They are as follows:
Prokaryotes. Eukaryotes. What do you mean by Cell structure?The structure of a cell may be defined as the components through which it has developed. It includes the cell membrane, the nucleus, and the cytoplasm. The cell membrane is a semi-permeable membrane that separates the inner atmosphere of the cell from the outer environment.
The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made. When it comes to prokaryotes, they lack a well-defined nucleus and other membrane-bound cell organelles.
Eukaryotic cells generally have a well-defined nucleus and other membrane-bound cell organelles. Apart from this, these types of cells are generally highly compartmentalized as compared to prokaryotic cells.
Therefore, the classification of living things significantly depends on the structure of their cells that has been described above.

describe the unique intercellular connections between muscle cell
The unique intercellular connections between muscle cells are called intercalated discs. They are in the cardiac muscle. An intercalated disc has gap junctions and desmosomes, which are two ways that cells use to communicate with each other. Gap junctions connect neighbor cells, and desmosomes keep the cardiac cells together.
Cardiac cells are connected by intercalated discs, which has two structures:
Gap Junctions:They are channels that communicate cells that are next to each other. Gap junctions allow the passage of ions quickly so that all the cardiac fibers can contract in a coordinated and fast way.
Desmosomes:They are at the ends of the cardiac fibers, and they hold the cells together thanks to the different proteins that form this structure. As they can resist a lot of effort, they are one of the cardiac cell's junctions.
