The sole reason why red blood cells are unable to replace damaged proteins is that red blood cells lack DNA and cell organelles such as the nucleus, ribosomes, and mitochondria which are crucial for protein synthesis, assembly, and repair. In other words, they lack both the information and the machinery for making or repair of proteins.
Due to lack of DNA and cell organelles, red blood cells cannot be able to satisfy the central dogma which summarizes synthesis of proteins as DNA → RNA → proteins.
DNA has the genetic information on how proteins should be made, RNA is responsible for transferring the information from DNA in the cell nucleus to the ribosomes in the cytoplasm, then translating or decoding this information, which results in the making of protein.
Answer:
The answer is: All of the options
Explanation:
These three clues (Ancient life forms preserved as fossils can tell us what organisms existed and where they were. Matching the fossils can show that land masses were once connected, Matching rock type and rock formations can show the way the continents were once attached, Glacial evidence has been found in areas where glaciers could not exits if the continents were in their current location.) can all tell us that continents and landmasses were together at one time. You can do all three to find out the answer.
Because it's a green plant we can consider fern as a producer
Answer:
7.5cm
Explanation:
Velocity vs Time Graph:
When the object is going along the plane with velocity v at a particular time interval t we can explain it's motion via the velocity vs time graph. If the velocity of the object is constant then velocity vs time graph will produce a horizontal straight line. If the amount of differentiation of velocity of the object is positive and constant then the graph shows the linear line whose slope is is the same as the ratio of the change in velocity to the time interval.
Velocity vs time graph:
Is shown in the attached image
A velocity-time graph helps us to estimate the distance traveled by using the area under the graph.
Height of the triangle is the velocity (v) = 0.75m/s
The base of the triangle is the time interval (t) = 0.2sec
Distance travelled = Area of triangle
Distance travelled
= 1/2(V) * t
= 1/2(0.75m/s) * 0.2s
= 0.0075m
=7.5cm
Thus, during one beat blood flows 7.5 cm
