Answer: (I HOPE THIS HELPS) Antlions experience competition when there is a scarcity of food and few spaces to burrow in the sand. This happens during their larval stage when there is an overlap on their reproduction where the large ones consume the small ones for survival.
The correct answer to this question is that:
The idea of Karyotyping is that it helps us to know the sex of a person and it gives us information whether there are chromosomal disorder or not. As a whole, it won't tell us the traits of a person because those traits are acquired how he or she interacts with the society.
I believe the correct answer from the choices listed above is option D. The animals are more closely related according to Linnaeus's system of classification when the two animals share traits at the genus level.
Hope this answers the question. Have a nice day.
Answer:
1000, 2000 and 3000.
Explanation:
The example given in the question is of a DNA with 4000 base pairs and it is being cut at 1000 pairs, 1500 pairs and 3000 pairs. So the lenghts of the segments that are cut from the original spiral are 1000, 500, 1500 and 1000 respectively. And the information that only the linear fragments are being produced is given to us in the question so the sizes of DNA expected would be 2000, 1000, 3000 and 2000 again respectively.
I hope this answer helps.
· In an open system matter and energy can be transferred
· In a closed system only energy can be exchanged
· In an isolated system neither matter nor energy can be exchanged
· The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system
· As an open system the cell allows nutrients to enter the cell and waste products to exit the cell
· The cell does this through the use of a semi-permeable membrane
· It needs nutrients in the forms of glucose, ions and many other molecules.
· The nutrients can come into the cell through either passive or active transport
· In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.
· During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.
