Yes and no. Everyone's heart works the same way, is made of the same type of tissue and is located in the same part of the body. However, there are people with diseases who have hearts that are in worse condition and may look different. For example, people with coronary artery disease experience plaque build up in their coronary arteries, which causes a reduction of blood flow to the heart, and in order to treat this they may get a bypass surgery in which another blood vessel from somewhere else in the body, would be used to bypass the blocked blood vessel. In this case the anatomy of that person's heart would be slightly different.
Answer:
B
Explanation:
A is just false- there is no bacteria or other organisms inside cells.
C is incorrect because cells have lots of different things inside them
D is only referring to the cytoplasm in cells.
Answer:
All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell;
Explanation:
Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
