Answer:
Primary succession is one type of the ecological succession which takes place on the land devoid of vegetation or barren land.
The species which first flourishes on this barren land are known as pioneer species which includes the species of bryophytes and pteridophytes like lichens and mosses.
These lichens and mosses help breakdown the barren rocks through chemical leaching and help increase the nutrient content. This allows the ferns and small pteridophytes to grow.
Then the area is colonized by the intermediate species which includes herbs, shrubs later trees. These intermediate species help attract the animals and thus help establish the biological community.
Thus, Lichens mosses → herbs→ shrubs →trees.
The cell organ that makes proteins is the ribosomes

Three different LTM kinds exist: Three types of memory exist: (1) semantic memory, which stores factual information, such as the distinction between afferent and efferent nerves; (2) episodic memory, which stores details of specific experiences.
Such as your first day of work; and (3) procedural memory, which stores instructions. While episodic memory is the recollection of specific facts, semantic memory is the recall of generic facts. The two categories of long-term memory are declarative memory and procedural memory. Declarative memory is the ability to recall events, facts, and data. The memory of how to perform things is referred to as procedural memory.

Answer:
The type of treatment indicated to treat infertility due to blockage of the vas deferens is surgery to remove the obstruction (option C).
Explanation:
Blockage of the vas deferens is a known cause of obstructive azoospermia, which prevents the passage of sperm and causes infertility. This type of obstruction can be corrected by surgery, part of the treatment of infertility from this cause.
The vas deferens are in charge of conducting the sperm from the testicles to the ejaculatory ducts, which prevents these gametes from being expelled to fulfill their function in reproduction.
The other options are not correct because:
<em> A. </em><u><em>Medication to stimulate sperm production</em></u><em> does not resolve the blockage.
</em>
<em> B. </em><u><em>Hormone therapy to increase testosterone </em></u><em>could be considered for infertility treatment, but the obstructive problem continues.
</em>
<em> D. </em><u><em>Semen implantation in the testes</em></u><em> does not exist as a medical treatment.</em>
