Answer: Option C.
Inefficient oxygen transportation.
Explanation:
Sickle cell anaemia is an inheritable condition in which the red blood cells cannot carry oxygen to the organs or whole body because the red blood cells shape has been distorted and is sickle in shape. In this condition there is not enough red blood cells to carry oxygen in the blood.
Red blood cells function to transport oxygen in the blood because of the haemoglobin molecule present in them.
This can damage the organs nerves,lungs, livers spleen e.t.c
The correct answer is going to be <span>C. It is the continuous movement of water under, on or above the Earth's surface</span>
The crossing over is a process that is essential to human genetic diversity. During the crossing over parts of the homologous chromosomes ( two chromosomes identical by structure, but different in origin, one inherited from the mother and one from the father) randomly exchange parts of their sequences.
If the crossing-over didn't exist, this would greatly decrease the genetic diversity, because the chromosomes would always bee passed o the next generations unchanged.
Answer:
Para determinar la distancia a la que se encuentra una gaviota respecto del nivel del mar, es necesario medir la altura a la que se encuentra volando. Así, dado que el nivel del mar tiene una altura considerada como de 0 metros, si la gaviota está volando a unos 500 metros de altura, por ejemplo, esa será su distancia respecto del nivel del mar.
Answer:
a. All of the answers are correct.
Explanation:
During conjugation a bacteria transfers it's genetic material to another bacteria. The genetic material has genes in a particular order so we can easily know the order of the genes through experimentation. The transfer of genes occurs as per the time allowed. If two genes are nearby then they will be transferred one after the other.
For example in the given question, gene A was transferred to recipient bacteria in 26 minutes, gene M was transferred in 37 minutes while gene T was transferred in 45 minutes, it simply means that the order of genes is A M T. Gene M was transferred to another bacteria after A was transferred because time required to transfer it is 37 minutes which is less than time required to transfer A which is 26 minutes. Gene T took maximum time to get transferred so it will be last to be transferred.
After calculation, we can easily infer that the genetic distance between A and M is 11 minutes (37 minutes - 26 minutes = 11 minutes). Similarly we can get genetic distance between A and T as 19 minutes and between M and T as 8 minutes. So all the given options are correct.
