The statements that correctly describe centrioles are that they are only found in animal cells and spindle fibers are connected to centrioles. Therefore, the correct option is A and B.
What are centrioles?Centrioles are cylindrical structures found in animal cells that play a role in cell division.
Statement A- Centrioles are only found in animal cells and not in plant cells or bacteria. Hence, it is correct.
Statement B—The spindle fibers are connected to centrioles and play a crucial role in pulling the chromosomes apart during cell division. Hence, it is also correct.
Statement C- Incorrect, as centrioles are present throughout the cell cycle, not just during the metaphase stage.
Statement D- Incorrect, as chromosomes and centrioles are not made of the same material. Chromosomes are composed of DNA, while centrioles are made of microtubules. Therefore, the correct option is A and B.

Which weather patterns are caused by atmospheric pressure differences?
Answer:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies.
Explanation:
Storms, which are severe weather conditions, develop when air pressure differences speed up air flow.
What do you mean by atmospheric pressure differences ?It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. Weather is predicted by atmospheric pressure. There will often be clouds, wind, and precipitation when a low-pressure system enters a region. Fair, quiet weather is frequently a result of high pressure systems.
Air density variations, which are connected to temperature, are what are causing this shift in pressure. Because heated air's gas molecules move faster and further apart than cooler air's, warmer air is less dense than colder air.
Thus, various weather patterns are seen with change of atmospheric pressure.

Answer:
B. Mitochondria
Explanation:
Mitochondria is the cell’s powerhouse, these organelles are the main suppliers of energy without these organelles; nutrients are unable to be converted to usable ATP which is needed for many vital jobs including cAMP mediated transport. In addition, when looking at histology, tissues with many mitochondria organelles, which looks like spots, will most likely be muscle tissues.
