Buckets don't hold much meaning to the dogs and wolves.
In the bucket experiment,
the dogs were equally likely to seek food from the person with a bucket over
his head as the person holding the bucket. Most dogs haven't learned to read
the cue because they don't typically see a person with a bucket over his head.
Monique Udell said:
“For us as
humans, having a bucket over your head is very silly,’’ she said. “Dogs and
wolves don’t get that. For the most part dogs and wolves would be equally
likely to beg from someone with a bucket on your head because buckets don’t
hold much meaning.’’

Answer:
The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity. ... When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system.
Explanation:
Answer:
The baby is clone of mature animal from which normal body cell was taken.
Explanation:
Three mothers or parents are involved in this process:
1. the one who donated the egg cell
2. the one from which body cell or DNA content was taken
3. the surrogate mother
The DNA content was removed from the egg cell. Thus, this animal did not contribute any DNA content to the cloned baby. Hence, it cannot be a biological mother of the clone.
3. This mother only contributes to nutrition and development of the baby. However, did not contribute any DNA content and thus, it is also not a biological mother.
2. The mature animal contributed whole genetic content of the clone. It is his or her DNA which was cloned into the enucleated egg. Thus, it is biological parent of the clone.
Answer:
system
Explanation:
All organisms have some sort of biological organization which begins with atoms that join together to form molecules and macromolecules. These atoms and molecules make up the organelles such as mitochondria, nucleus of a cell. Several organelles associate to form a cell which is a basic unit of life
When different cells associate together, they form tissues such as bone tissues. A collection of several tissues makes up an organ such as bone to perform a specific task. Several organs associate to perform body functions. This group of organs is referred to as <em>an organ system</em>. For example, the skeletal system is made up of bones, cartilage, tendons and ligaments. They work together to perform various functions such as movement, creating of red blood cells etc.
