Answer:
In the given case, in my opinion, one should perform the experiment in a similar manner with no change. An experiment is done many times in order to omit any influences of sampling or handling on the outcomes of the study. For this purpose, the repetitive experiments have to be performed in a similar way as the previous ones were performed. After that, the outcomes of the repetitive experiment and the initial one are compared.
If any conditions or variables are changed in the experiment, the outcomes of the repeated experiment cannot be compared with the initial one. As variations in experimental material, variables, or procedure would have influenced the outcomes.
A chemical equation is said to be balanced when the number of atoms of each element on the reactant side is equal to the number of atoms of those elements on the product side.
The process of photosynthesis involves carbon dioxide and water, which reacted together to form glucose and oxygen. The balanced equation for photosynthesis is given below:
6H2O + 6CO2 = C6H12O6 + 6O2.
Looking at this chemical equation, you will discover that: there are 12 atom of hydrogen, 18 atoms of oxygen and 6 atoms of carbon on both sides of the equation.
Answer:
1-They have their own DNA, which is separate from the DNA found in the nucleus of the cell. 2- both organelles use their DNA to produce many proteins and enzymes required for their function. 3- A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host.
Explanation:
A vein is a blood vessel that conducts blood toward the heart. Compared to arteries, veins are thin-walled vessels with large and irregular lumens.
<h3>Where are blood vessels found in your body?</h3>
- Blood is delivered to human tissues by arteries, which act as conduits or channels. Two tube-like closed systems comprised of the vessels start and stop at the heart. Blood is transported from the right ventricle to the lungs and back to the left atrium by one system, the pulmonary arteries.
- Your circulatory system is made up of blood vessels and heart vessels. About 60,000 miles of blood arteries make up your body.
- Blood is carried through blood arteries throughout the body. Blood is carried away from the heart through arteries. The blood is brought back to the heart by veins. Body cells and tissues are surrounded by capillaries that transport and absorb nutrition, oxygen, and other chemicals.
- Blood vessels are the channels or conduits through which blood is distributed to body tissues.
- The arteries (red) carry oxygen and nutrients away from your heart to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.
