Answer:
The humans use this limb to grab things, body language, and sign language.
The dogs use this limb for all kinds of weight-bearing activities like walking, jumping, running et cetera.
Birds use this to fly and whales use it as flapper.
The limbs of all these four animals are the example of homologous organs that is, they all are similar in structure but adapted to perform different functions during the course of evolution.
For example, in all four organisms, the limb is made up of the same set of bones such as humerus, radius, ulna, carpals, metacarpals, and phalanges.
Homology in structure shows that they must have evolved from a common ancestor and diverge to perform different functions as an adaptation to the contrasting environment.
<span>Red blood cells normally have a biconcave shape (picture a donut, but instead of a hole through the centre there's just a downward slope to the centre of the cell). If the cell takes on water, it will increase in size and the sloped areas will start to flatten out. If the cell loses water, it will begin to shrivel. Use these observations and your understanding of osmosis to answer the question!</span>
Answer:
sickle cell disease or sickle cell disease is about the inheritance of metaplastic cells or cells that do not respect normal cell morphology from the mother or father to a child.
This is not associated with cultures, instead lactose tolerance is.
Explanation:
Lactose tolerance is basically an adaptation of the body in those humans who continue to drink milk throughout their lives, once the growth stage is over, milk should be suspended, although some continue to consume it and lactase continues to be encoded and expressed.
Some people for cultural reasons or environmentalist lifestyles do not drink animal milk, but rather vegetable milk.
Percent error is a statistical tool used for evaluating precision. It is expressed as:
Percent error = | (experimental value - theoretical value) / theoretical value | x 100%
Experimental value represents the calculated value while the theoretical value represents the known value. A percent error value which is approaching zero means that your experimental value is close to the known value. Which can possibly mean that you have precise measurements. Calculations are as follows:
Percent Error = | (2.54 - 2.70) / 2.70 | x 100 =5.93%
Thus, the answer is b. 5.93%.
