Any cells of the human body, except the cells of a placenta.
Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.
Case 1: Corn to human:
Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.
Case 2: Corn to cow to human:
Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.
It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
Answer:
population size, population density, when scientists population spacing and age structure
Explanation:
because because four characteristics is defined a population and i kind of just know.
Answer:
b. The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.
For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
Answer:
Lining up of chromosomes in the cell
.
Explanation:
Prophase begins with the Thickening of chromosome. Chromosomes are clearly visible inside the nucleus. each chromosome splits longitudinally to form two chromatids.
The centriole in the centrosome of animal cell divides into two. The centrosphere set the centrioles free. Centrioles develop very fine eye-lash like thread called aster rays. the two asters start moving towards the opposite poles. By the end of prophase they reach at the opposite poles.
