identify three effects of physical activity on the respiratory system
Answer:
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.

to which organ does the blood flow to after it leaves the heart and what happens when it reaches that organ
Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery, and to the lungs. Blood leaves the heart through the aortic valve, into the aorta, and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs, and body.
Explanation:
Answer:
*
Explanation:
- When the blood leaves the heart it flows to the lungs
- In the lungs, the blood refills its oxygen supply and gets rid of carbon dioxide. The oxygenated blood returns from the lungs to the left atrium through the pulmonary veins to the heart
- The blood travels to your lungs so that you can breathe out the carbon dioxide and breathe in more oxygen.

What is aerobic respiration?Aerobic respiration: This is the process of cellular respiration that occurs in the presence of oxygen gas to extract energy from food. This type of breathing is common to most plants and animals, birds, humans, and other mammals. The end products are water and carbon dioxide.
Aerobic respiration is the process of using oxygen to break down glucose, amino acids, and fatty acids to produce ATP.
Pyruvate is then converted to acetyl-CoA in the mitochondrial matrix. The Krebs cycle occurs twice per glucose molecule. ATP synthase generates ATP from ADP and inorganic phosphate. The electron transport chain is the main channel for the production of ATP in all organisms.

why would dna evidence also be a type of homologous trait
Answer:
Homology is the relationship between structures or DNA derived from the most recent common ancestor. Although these two structures do not look similar or have the same function, genetically, they come from the same structure of the last common ancestor.
Explanation:
1. When would it be easier for a bear to catch a fish: as the fish swims or when it jumps in the air? Use your knowledge of how light travels in air and water to explain.
2. Why do objects at the bottom of an aquarium filled with water appear closer than they actually are?
The objects at the bottom of the aquarium appear closer than they are for the same reason that it is easier for bears to catch a fish once it jumps out of the water, because water bends light.
How does water bend light?Light travels in waves. When these waves reach an object most of them are reflected and some are absorbed. The absorbed light determines the color of the object and how we perceive it. When light waves travel through water, they slow down and slightly change direction, creating a sort of optical illusion as to the true position of the objects underneath.
Therefore, we can confirm that the objects at the bottom of the aquarium appear closer than they are for the same reason that it is easier for bears to catch a fish once it jumps out of the water, because water bends light.

Answer:
In order to be able to calculate the volume of oxygen gas produced by this reaction, you need to know the conditions for pressure and temperature.
Since no mention of those conditions was made, I'll assume that the reaction takes place at STP, Standard Temperature and Pressure.
STP conditions are defined as a pressure of
100 kPa
and a temperature of
0
∘
C
. Under these conditions for pressure and temperature, one mole of any ideal gas occupies
22.7 L
- this is known as the molar volume of a gas at STP.
So, in order to find the volume of oxygen gas at STP, you need to know how many moles of oxygen are produced by this reaction.

In a person with a disease in which the mitochondria do not produce enough energy for the cell, which organs would be the most severely affected
The heart would be one of the most affected organs if the mitochondria do not produce enough energy, since this organ requires a lot of energy, so any supply failure leads to heart failure and contraction failure.
What are mitochondria?They are the cellular structures responsible for supplying most of the energy necessary for cellular activity.
Characteristics of mitochondriaThey produce energy from the metabolism of organic fuels such as sugars, lipids (fatty acids) and amino acids.Insufficient energy production by the mitochondria causes dilated cardiomyopathy, where the heart undergoes significant dilation and loses the force of contraction.Therefore, we can conclude that a defect in a mitochondrial process involved in energy production would affect heart cells causing dilated cardiomyopathy, heart failure.

ILL Give brainliest, Why is diabetes a serious disease?
Because you have to go to lots of doctor’s appointments
Because every cell in your body needs glucose to live
Because you have to give yourself insulin shots
Because you can’t eat what you want anymore
Answer:
When there isn't enough insulin or cells stop responding to insulin, too much blood sugar stays in your bloodstream. Over time, that can cause serious health problems, such as heart disease, vision loss, and kidney disease.
Diabetes is a serious disease because you have to give yourself insulin shots.
What is insulin?The INS gene in humans encodes insulin, a peptide hormone generated mostly via beta cells within the pancreas.
What is Diabetes?When the blood glucose, commonly known as blood sugar, would be too high, then develop diabetes.
Diabetes develops when the pancreatic, a gland located behind the stomach, either produces insufficient amounts of the hormone insulin or even when the body has trouble utilizing it. Insulin aids in the movement of circulation sugar towards cells. Sugar becomes transformed into energy once within the cells, either for now or for later.
Therefore, the correct answer will be an option (C).

What are the 4 synthesis from beginning to end
Answer:
Photosynthesis is the process that allows plants to gather energy from the sun and transform it into energy they can use. How exactly does the process of photosynthesis work? Creating a model of a cell or examining a diagram can help you understand the process of photosynthesis. The diagram found above will give you some quick intuition about the process, letting you see its primary components. However, to gain a thorough understanding of the photosynthesis process, we’ll want to go over the process in more detail and examine how each of the component pieces operates. Let’s begin by taking a look at the reactants of photosynthesis. The necessary components or ingredients for photosynthesis include light energy, oxygen, carbon dioxide, and water. These are referred to as the reactant's photosynthesis. The cells of the plant will take in carbon dioxide, water, and sunlight and convert it into usable energy through photosynthesis. Given that carbon dioxide and water are the necessary ingredients for the creation of glucose, or sugar, the chemical equation for photosynthesis can be represented in this form:
6 CO2 + 6 H2O → C6H12O6 + 6 O2

Why does water expand
Answer:
this happens when it freezes
Explanation:
When water freezes, its molecules get arranged in a crystalline structure, thereby attaining a defined shape. This crystalline structure is less dense, and since there are gaps between individual molecules in the structure, the overall volume increases and water expands
Answer:
Water expands as it freezes because water molecules are very loosely bound. They are arranged in a hexagonal pattern inside of the ice. As the temperature lowers, the molecules move slower, which causes them to get closer together.

Do you think that a biotic or a abiotic factor can be both positive and negative in the same environment?
Explain.
No, biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment. Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH.Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition... The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment.
