Answer: respiratory system
Explanation:
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide
Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell's cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

a _________ is an example of an endotherm, and a ________ is an example of an ectotherm.
Answer: People, polar bears, penguins, and prairie dogs, like most other birds and mammals, are endotherms. Iguanas and rattlesnakes, like most other reptiles—along with most fishes, amphibians, and invertebrates—are ectotherms.
how do ectotherms primarily control their body temperature?
Answer:
Ectotherms control their body temperature by relying on coverage of fur or feathers, which act as insulation. ... Brown fat has capillaries that transport heat throughout the body to warm it Brown fat cells have less cytoplasm, which prevents heat loss from the body.

Can a virus cause a change in your DNA?
Please answer this don’t just take the points please I need help
Answer:
Yes , when viruses infect us, they can embed small chunks of their genetic material in our DNA. Although infrequent, the incorporation of this material into the human genome has been occurring for millions of years. As a result of this ongoing process, viral genetic material comprises nearly 10 percent of the modern human genome. Over time, the vast majority of viral invaders populating our genome have mutated to the point that they no longer lead to active infections. But, as scientists funded by the National Institutes of Health have demonstrated, they are not entirely dormant.
Explanation:
Answer:
Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when co infecting viruses exchange genetic information, creating a novel virus.

which of these are the repeating units that form DNA molecules?
a. fatty acids
b.nucleotides
c.amino acids
d.chromosomes
Answer:
d.chromosomes
Explanation:
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation

why is it important photosynthetic organisms to have access to water
Answer:
Plants also need water for photosynthesis. Photosynthesis is what plants do to create their food, and water is critical to this process. ... The water from the leaves evaporates through the stomata, and carbon dioxide enters the stomata, taking the water's place. Plants need this carbon dioxide to make food.
Choose the answer that correctly lists, in chronological order, the events involved in synaptic transmission.
a: A nerve impulse reaches the synaptic knob.
b: Neurotransmitter molecules diffuse across the synaptic cleft.
c: A nerve impulse begins in the postsynaptic cell.
d: Neurotransmitter molecules bind to receptors in the postsynaptic cell.
e: A voltage change occurs in the postsynaptic cell.
Answer: hi im brain bot
im not sure i know this one im stumped
Explanation:
The event occurs as nerve impulse reaches the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell and voltage change occurs in the postsynaptic cell. A nerve impulse begins in the postsynaptic cell. The correct option is C.
What is synaptic transmission?The metabolic pathway by which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
Chemical synaptic transmission is characterized by the release of a neurotransmitter from the presynaptic neuron and the binding of the neurotransmitter to specific post-synaptic receptors.
Synaptic transmission is the process by which a nerve impulse (action potential) travels from the presynaptic neuron to the post-synaptic neuron across the synaptic gap. An action potential is an electrical impulse that travels down the axon of a neuron.
As the nerve impulse arrives at the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell, causing voltage changes in the cell. and finally nerve impulse begins in the postsynaptic cell.
Thus, the correct option is C.

why would an ecosystem with only a few different types of organisms have a less complex food web than an ecosystem with many different of organisms
Answer:
An ecosystem with only a few different types of organisms has a less complex food web than those with many different types because in a less complex food web, only a few organisms are needed to be presented, more nutrients are absorbed and less energy is needed to complete the food web.

Sofia’s favorite meal is breakfast, and she is careful to include healthy components along with her favorite foods. She knows breakfast helps to keep her energy levels up until lunch. Sophia's digestive system helps her body get energy from food. How do the nutrients from food get to the body's cells? A. The nutrients are distributed by the digestive system to the parts of the body that need them. B. The nutrients are picked up and transported around the body by blood from the circulatory system. C. The nutrients are absorbed directly into the cells that need them. D. The circulatory system brings nutrients to the digestive system to be processed for the cells.
Answer: c
Explanation:because it needs cells I think…
The nutrients from the food get to the cells of the body by the action of two organ systems i.e. the digestive system and the circulatory system.
What is the role of the digestive system?The digestive system may be defined as a type of organ system that significantly deals with the breakdown of food substances into simpler components that can easily be consumed by the body.
According to the context of the question, the food that we eat reaches the stomach through the esophagus where multiple enzymes perform their roles. After the stomach, the food may be passed to the small intestine which is absorbed here and then the nutrients assimilate in the blood.
Through the blood, the nutrient can be transported around the body by blood from the circulatory system. Thus, the correct option for this question is B.
