When an object is moving around in a circulation motion with constant speed then even if the movement is constant still the velocity is changing at each pointbecause of the change in the direction at each point. If the velocity is changing at each point then that means the object is accelerating.
But, in linear motion if an object has constant movement then the acceleration is considered zero because there is no change in the direction so velocity change is considered zero.
Since the carousel in this question is moving in the circular motion so it means that its direction is changing at each point which implies that its velocity is changing leading to acceleration.
Chloroplasts are found in plant cells, they make up the green pigment ( chlorophyll ) which manufactures food for the plant during photosynthesis process.
When a gene is present on the X chromosome, but not on the Y chromosome, it is said to be X-linked. X-linked genes have different inheritance patterns than genes on non-sex chromosomes (autosomes). That's because these genes are present in different copy numbers in males and females.
Drinking through a straw shows fluid flowing from high pressure to low pressure in 2 ways. The first is how it shows high pressure as you stuck on the straw. This increases the pressure and brings the fluid to your mouth. If this pressure is kept you can successfully pick up the straw filled with water and have none come out. This demonstrates low pressure when you stop ducking and the fluid falls back down the straw into your cup.
Prokaryotes lack a defined nucleus (which is where DNA and RNA are stored in eukaryotic cells), mitochondria, ER, golgi apparatus, and so on. In addition to the lack of organelles, prokaryotic cells also lack a cytoskeleton.
