Answer:
Embryo
Explanation:
An embryo refers to the early stage of development of a multi-cellular organism and it occurs just immediately after fertilization. This development often continues through the formation of cell, tissues, organs.
An embryo is formed from the fertilization of a female ova by a male sperm.
The answer is;
a. add electric current.
b. add buffer solution
The process of gel electrophoresis taps on the property of net charges of molecules to ensure that they travel up the gel. Additionally, the buffer acts as the mobile phase for the molecules and also give molecules net charge as they travel through the gel. It is until the molecules reaches an isoelectric point,where the molecule has zero net charge, that they stops moving through the gel. This is how bands are formed.
The graph is showing how primary production decreases as deep increases. It is due to the amount of available light in the water.
<h3>Primary production on the ocean</h3>
The primary production in the ocean is performed by microorganisms known as phytoplankton.
Phytoplankton populations are primary producers that include bacteria and algae, which use photosynthesis to produce biomass and release oxygen.
In a similar manner to plants, phytoplankton communities also contain chlorophyll in order to convert sunlight into biomass.
As ocean deep increases, the amount of available light in the water decreases, thereby also decreasing the primary production of the phytoplankton populations.
