Here is your answer......
Explanation:
Monotremes are mammals that lay eggs. Monotremes are warm blooded with a fast metabolism. They have hairy bodies to keep warm.
Marsupials are mammals that give birth to live young. These mammals have a pouch where their young grow and develop. Marsupials are hairy, warm blooded, and produce milk. One of the biggest differences between marsupials and placental mammals is that marsupials give birth quite early and rely less on the nourishment of the placenta. Some examples of marsupials are kangaroo and opossums.
Placental mammals are mammals that give birth to fully developed live young. They differ from marsupials in that the baby spend more time being nourished in-utero by the placenta. These mammals are hairy and warm blooded as well. Some examples are mice, rats, and bats

Answer: The upper gastrointestinal tracts organs consist Esophagus, stomach and duodenum.
Explanation:
Gastrointestinal tracts is a organ system found in human beings and other animals that deals with intake of food, digestion of food, adsorbing nutrients from the digested food and expelling or excreting the waste products and undigested food.
The gastrointestinal tracts is divided into two, the upper and lower gastrointestinal tracts. The upper gastrointestinal tracts organs consist of Esophagus, stomach and duodenum while the lower gastrointestinal tracts consist of the large and small intestine. The structures include anus, colon,rectum,caecum.
Answer:
The correct answer is B. generalism.
Explanation:
Mutualism is a symbiotic relationship wherein both organisms benefit from the other’s presence. Parasitism is a symbiotic relationship wherein one organism benefits at the expense of the other organism, which is harmed. Finally, commensalism is a symbiotic relationship wherein one organism benefits and the other is neither helped nor harmed. Generalism does not refer to a symbiotic relationship and thus is the correct response.

Answer:
D
Explanation:
<em>The correct option here would be</em><em> D</em><em>.</em>
The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.
For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.
Hence, the correct order of a typical endomembrane system function would be:
- <em>Ribosomes on the RER synthesize proteins.</em>
- <em>Proteins are packaged into transport vesicles.</em>
- <em>Golgi apparatus receives transport vesicles from the RER.</em>
- <em>Proteins are modified by the Golgi apparatus.</em>
- <em>Modified proteins may be secreted from the cell by exocytosis.</em>
