Answer:
Electrons are much smaller in mass
Explanation:
Although similar in mass, protons are positively charged, while neutrons have no charge. Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Electrons are much smaller in mass than protons, weighing only 9.11 × 10−28 grams, or about 1/1800 of an atomic mass unit.

What is an organism that obtains energy by feeding on other organisms can eat both producers and consumers?
An organism that obtains energy by feeding on other organisms and can eat both producers and consumers is called a tertiary consumer.
Tertiary consumers are at the top of the food chain and feed on secondary consumers, which feed on primary consumers, which feed on producers. Producers are organisms that can produce their own food through photosynthesis or chemosynthesis, while consumers cannot produce their own food and must feed on other organisms. Tertiary consumers, also known as apex predators, are top-level carnivores that feed on other predators and scavengers.
Examples of tertiary consumers include large predatory birds such as eagles and owls, large carnivorous mammals such as wolves and lions, and some species of fish such as sharks.

Why is delayed stomach emptying important for lipid digestion? enter your answer here check answer
Delayed stomach emptying is important for lipid digestion because lipids can be easily emulsified, digested and absorbed by small intestine as they move along with bile salts slowly due to the fatty content of meal taken.
What is lipid?Lipids are any organic molecules that are soluble in fat or oil but not in water. They include lipids, waxes, oils, hormones, and some membrane components and act as chemical messengers and energy storage molecules. Lipids serve a variety of functions both inside the body and in food. The body uses lipids to store energy, control hormones, transmit nerve impulses, protect sensitive organs, and move nutrients that are fat-soluble.

Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
Mathematical representations are a powerful tool for illustrating the cycling of matter and flow of energy among organisms in an ecosystem.
Energy and matter are continually cycling through ecosystems in a process called the biogeochemical cycle. This cycle describes how elements such as carbon, nitrogen, and phosphorus move through living and nonliving parts of an ecosystem. For example, plants take in carbon dioxide from the atmosphere and use it to build organic compounds through photosynthesis. These organic compounds are then consumed by animals, and when these animals die, their bodies decompose, releasing carbon back into the atmosphere in the form of carbon dioxide. Meanwhile, energy flows through ecosystems in a unidirectional manner, starting with the sun as the ultimate source. Producers, such as plants, use the energy from the sun to create organic compounds through photosynthesis.
This equation illustrates how energy is lost as it is transferred from producers to consumers.4. Food webs and energy pyramids:Food webs and energy pyramids are visual models that represent the flow of energy through different trophic levels in an ecosystem. Food webs show the relationships between different organisms in an ecosystem, while energy pyramids show the amount of energy available at each trophic level. These models can help us understand how changes in one part of the system can impact other parts and how the cycling of matter and flow of energy are interconnected in an ecosystem.In conclusion, mathematical representations are a powerful tool for illustrating the cycling of matter and flow of energy among organisms in an ecosystem.

A researcher investigated a blood disease carried by birds she isolated an organism from the blood of an infected bird she finds that the organism is unicellular and has a nucleus a cell wall and the ability to produce spores what kingdom does the organism belong to
The researcher who conducted an investigation on a blood disease carried by birds found out that the organism is unicellular and has a nucleus, cell wall, and the ability to produce spores. Based on this information, the organism belongs to the Kingdom Fungi.
The kingdom Fungi consists of unicellular and multicellular organisms that lack chlorophyll and reproduce asexually and sexually by forming spores. They are heterotrophic organisms, which means they depend on other organisms for their food. Fungi cells have a cell wall made up of chitin, which provides strength and rigidity to the cell wall. The cytoplasm of the fungal cells contains many specialized organelles, including nuclei, ribosomes, mitochondria, and Golgi bodies that carry out various metabolic activities.
The researcher's findings suggest that the organism is a unicellular fungus with a nucleus, cell wall, and the ability to produce spores. Spores play a crucial role in the fungal life cycle, as they allow the organism to reproduce and spread to new habitats. These spores can be transported by wind, water, or other organisms to colonize new areas.
In conclusion, based on the researcher's investigation, the organism she isolated from the blood of an infected bird belongs to the Kingdom Fungi.

t/f Physical features cluster into discrete genetic units.
The statement "Physical features cluster into discrete genetic units" is False. While physical features can be influenced by genetic factors, they do not cluster into discrete genetic units.
Physical traits, such as height or eye color, are typically influenced by multiple genes and environmental factors, and can vary widely even within a single population. The idea of discrete genetic units is based on outdated notions of race, which posited that distinct groups of people could be categorized based on physical characteristics.
However, modern research has shown that genetic variation is not easily categorized into distinct groups, and that the genetic differences between individuals of the same racial or ethnic group can be greater than those between individuals of different groups. Therefore, physical features cannot be used to accurately determine genetic units.

in a simple synapse, neurotransmitter chemicals are received by the postsynaptic membrane, Somatic motor neurons are used to transmit motor signals to muscles.
A simple synapse involves the reception of neurotransmitter chemicals by the postsynaptic membrane, while somatic motor neurons are used to transmit motor signals to muscles.
A synapse is a structure or interface that permits the transfer of signals from one neuron to another. The structure of a synapse varies depending on the neuron type and the location in the nervous system. Synapses are classified into two types: chemical and electrical synapses. Chemical synapses utilize neurotransmitters to transfer signals between neurons. Electrical synapses use gap junctions that connect the cytoplasm of the two neurons, allowing electric current to flow between them.
Somatic motor neurons are the neurons that transmit signals to the skeletal muscles. They are responsible for voluntary movements and reflex arcs. When a somatic motor neuron is activated, it sends a signal to the muscle it innervates, resulting in muscle contraction. The neurotransmitter used at the neuromuscular junction is acetylcholine (ACh). When an action potential arrives at the presynaptic terminal of a somatic motor neuron, it causes the release of ACh into the synaptic cleft. The ACh binds to receptors on the postsynaptic membrane of the muscle fiber, which leads to depolarization of the muscle membrane and ultimately muscle contraction.
