Answer: Option C
Explanation:
The kingdom Protist and kingdom Fungi has some members that reproduce asexually. Asexual mode of reproduction can be defined as the process by which formation of zygote takes place without the involvement of male and female gametes.
The amoeba and paramecium divides by binary fission and the new individuals formed are identical to their parents.
Some species of fungi also reproduce asexually. Example: zoospores
<span>For calcium to be absorbed it must bind to a hormone regulated brush border protein called Calbindin.
Calbindins are calcium binding protein. As it names also shows that, Cal for calcium and bindin for binding. they are also described as vitamin D dependent calbindin proteins.
Calbindin-D9k and Calbindin-D28k are two identified forms of protein. </span>

Answer:
B (active transport using ATP)
Explanation:
Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.
In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).
An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.
