Prokaryotic cell don't undergo mitosis. If you observe a cell undergoing mitosis, then it is eukaryotic. In order for mitosis to occur, a nucleus must be present.
Moreover, Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus, meaning its DNA is surrounded by a membrane, and has other membrane-bound organelles. which allow the division of functions. The primary difference between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.

<h3><u>Turmeric powder can be adulterated in many different ways:</u></h3>
- Curcuma longa(Turmeric) is a strong base and is used as a domestic product.
<u>The possible adulteration and deterioration of Curcuma longa are as follows</u>:
- It can be mixed with chalk powder which results in production of small bubbles.
- When turmeric powder is mixed with water, it produces some streaks of soluble colour in water that is caused as a result of adulteration of lead chromate in turmeric powder.
Answer:
The development of the brain continues past childhood. For example, if a monkey pushes a lever with its finger several thousand times a day, the Brain tissue that controls the finger changes as a result of the experience.
Answer:
B. Blood in the left ventricle is deoxygenated.
Explanation:
Human heart consists of four chambers namely: right atrium, right ventricle, left atrium and left ventricle. These chambers work hand in hand to perform the function of circulating blood throughout the body.
- The RIGHT ATRIUM receives deoxygenated blood from the heart and passes it to the RIGHT VENTRICLE, which pumps it to the lungs in order to be oxygenated.
- The LEFT ATRIUM receives oxygenated blood from the lungs and passes it to the LEFT VENTRICLE, which pumps it into the body.
- Also, the pulmonary artery carries deoxygenated blood into the lungs for oxygenation while the pulmonary veins carry oxygenated blood from the lungs
Based on the above explanation of the right & left atria and the right & left ventricles, it is FALSE that the blood in the left ventricle is deoxygenated. It is rather oxygenated.
<span>Carcinogens are substances that are commonly known to cause cancer. The condition that might occur when a substance causes unregulated and uncontrolled cell growth and development is called cancer. Cancer can be life-threatening because the cells will grow rapidly causing tumor development. As the tumors become larger, there is a greater chance that the cells can spread to surrounding cell structures or body organs.</span>
