1. Testing only one variable
A controlled variable means its the one that stays the same. In a controlled experiment, it means there is only one manipulated, (changed) variable.
Answer:
Messenger RNA is a type of RNA that is necessary for protein production. In cells, mRNA uses the information in genes to create a blueprint for making proteins. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and does not alter DNA.
So the answer will be C or A
Explanation:
Answer:
Explanation: Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes. ... The vast majority of protists are unicellular or form colonies consisting of one or a couple of distinct kinds of cells, according to Simpson.
Answer:
The organelles in an animal cell are as follows:
cell membrane, nucleus, nucleolus, nuclear membrane, cytosol, smooth endoplasmic reticulum, rough endoplasmic reticulum, Golgi apparatus, ribosomes, mitochondria, centrosome, cytoskeleton, vacuoles, vesicles, and lysosomes.
Explanation:
An animal cell is a typical example of an eukaryotic cell i.e a cell that contains a membrane-bound nucleus. In the cell are certain structures that performs specific functions in the cell called ORGANELLES. The organelles, according to this question, are found suspended or cushioned in the cytoplasm of the animal cell.
A list of the organelles in the cytoplasm (part of the cell that excludes the nucleus) of an animal cell are as follows:
- cell membrane
- nucleus
- nucleolus
- nuclear membrane
- cytosol
- smooth endoplasmic reticulum
- rough endoplasmic reticulum
- Golgi apparatus
- ribosomes
- mitochondria
- centrosome
- cytoskeleton
- vacuoles
- vesicles
- lysosomes
Answer:
A dam that could allow fish to still pass through is a fishway/fish pass its a "fish ladder" that is structured on or around artificial or natural barriers to allow for fishes natural migration and the movement for potamodromous species.
