The second one would be my answer but also an answer that is not up there is that during an experiment when repeating the trials you might have to set up a new hypothesis every time and have to review the data several different times because of different results from each trial
hope this helps if not just let me know
Damage to your kidneys can cause wastes to build up in your body and lead to other health problems like heart disease , anemia,and bone disease. Also you can die without your kidneys
Answer: The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. Due to human activities, populations of many species have become small and isolated.

Animal regeneration can produce whole organism or parts of organism and repair injury.
Clones today are done at genetic level by using molecular biology techniques as compared to old days when only nucleus would be removed from the egg cell and desired nucleus is inserted for cloning.
Explanation:
Regeneration is a process in which whole organism or part of which is produced from pre existing cells or group of cells and tissue. Regeneration helps in maintaining the integrity of morphology and physiology.
In lower animals like hydra and planaria whole organism is generated by existing parts. This process is termed as totipotency.
In higher animals however injury repair by mitosis is an example of regeneration.
Plant structure involved in vegetative propagation are: bulbs, rhizomes and tubers.
Vegetative propagation can be done by grafting, cutting, bulb formation, tuber, layering and tissue culture methods.
Cloning is a process in which a genetical or identical copy of an organism or the cell is made by molecular biology techniques. The use of DNA sequences, molecular scissors, stem cells and plasmid are the latest techniques of cloning.
Cloning is used for treating serious diseases as diabetes and heart injury.
In old days one cell would have its nucleus removed and placed into the egg and eventually organism produced
Advantages of tissue culture:
From a single explants, large number of plants can be made.
Obtaining plants of desired trait from tissue culture is easy in short span.
No seeds are required for the growing of new plants.
