Name some organisms that reproduce through binary fission.
- Amoeba
- Pumilus
- Cereus
- Euglena
-----------------------------------------------------------------------------------------------------------------
If a organism reproduce through binary fission, they're dividing into two parts and the regeneration of those 2 parts. Mostly bacteria reproduce using binary fission and most cells do the same thing. It's a type a asexual reproduction. Like I said before, they divide instead of being one. The parent cell divides into 2 identical cells, growing into size.

1. An anatomy student was arguing with his grandfather. Granddad, who believed in folk wisdom, insisted that there are only five senses. The student, however, said that there are at least ten senses. Decide who is right, and then list all the senses.
Answer:
Granddad is right.
Explanation:
Granddad is right that there are five senses such as eyes, ears, skin, nose, and mouth. There are five sense organs that helps in sensing external environment present around the individual. Through eyes we can see our surrounding, ears can help us to hear different sounds, through skins we can sense the temperature of the surrounding, nose help us to smell different odors and mouth help us to taste different types of food. These five senses are very important for the survival of people.

Achromoplast stores while a leucoplast stores A. starch; pigments B. chlorophyll; starch C. pigments; chlorophyll D. pigments; starch
Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.
