Answer:
12.5m/s^2
Explanation:
Acceleration of an object can be calculated by using the formula;
a = v-u/t
Where; a= acceleration
v= final speed
u= initial speed
t= time
According to this question, the flying object is moving at 150m/s, meaning that ∆V = (v-u) is 150m/s, where initial speed is 0m/s.
Since time is 12s, the acceleration is thus:
a = 150-0/12
a= 150/12
a= 12.5
Hence, the acceleration of the flying object is 12.5m/s^2
Answer - Speciation
Reasoning - Pretty much what has happen was the two species has evolved over the course of evolution if you want to put it that way why the are incapable of breeding.
Answer: Hemoglobin SC disease is a type of sickle cell disease. People who have Hemoglobin SC disease (also called sickle-hemoglobin C disease) have red blood cells that contain both hemoglobin S and hemoglobin C.
Explanation:
Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
