Answer:
The process shown in the model requires energy from the cell.
Explanation:
Active transport refers to the movement of materials across the cell membrane against concentration gradient.
The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
Answer:
Differentiated cells have retained all their genetic potential
Explanation:
Differentiated cells are important in a multicellular organism because they are able to perform a specialised function in the body. Multicellular organisms must therefore retain some unspecialised cells that can replenish cells when needed. These unspecialised cells are called stem cells.
Answer:
the wind
Explanation:
the speed of wind could affect a storm adding with the rain
Answer:
The correct answer would be option D.
Explanation:
True breeding is a breeding procedure in which the parents would always produce their progeny with the same phenotype characters as the parents carry. This means for every trait these parents are homozygous so their offspring must show a similar phenotype.
In this case, all cattle are true-breeding which means they homozygous alleles show the progeny will also show similar traits which are short stature with brown hides and short horns.
Thus, the correct answer is option D.
