21. The smaller organelle is the ribosome.
I think it’s the glomerulus, hope this helps
Answer: 1. a video that shows a large river that has penguin populations on both sides.
Explanation:
Reproductive isolation is a phenomena which occurs when members of the same species becomes separated due to a geographical, physical or behavioral barrier. The members of the same species after separation adapt to changes and this is the basis of speciation or development of new species.
Option 1 is the correct option as the river is the geographical barrier, between the two separated penguin populations.
Answer:
Alright, sure thing.
Explanation:
a. Nucleoid- The nucleoid (meaning nucleus-like) is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material.
b. Mesosomes- Mesosomes or chondrioids are folded invaginations in the plasma membrane of bacteria that are produced by the chemical fixation techniques used to prepare samples for electron microscopy.
d. Capsid- A capsid is the protein shell of a virus, enclosing its genetic material.
e. Plasmalemma- The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment.
The nitrogen cycle is completed with the process of Denitrification
<h3><u>
Explanation:</u></h3>
Denitrification finishes the nitrogen cycle by transforming nitrate behind to vaporous nitrogen. Denitrifying bacteria are the doers of this method. These bacteria utilize nitrate alternately of oxygen while gaining energy, delivering nitrogen gas into the environment.
Denitrification relies on microbial action to crumble freely nitrogen-containing components. Bacilli absorb nitrate to generate energy, but in the method, denitrification transpires and nitrogen is diminished. Denitrification is an anaerobic means, transpiring chiefly in soils and deposits and anoxic zones in ponds and shores.
