Explanation:
Answer:
I would say chordates. (Not absolutely sure so double check)
Explanation:
Chordates have a dorsal nerve cord, which is super close to a spinal cord. (Which vertebrates have.)
Answer:
Option 3, of the abiotic factors found in their environment
Explanation:
The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.
The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case, if a bacteria lives in an environment where temperature is less than -5oC or higher than 50oC, then such habitats are considered to be “habitats with extremities” as special physiological mechanisms are required to maintain the homeostasis and survive.
Likewise absence of sunlight further adds to the extremities of the habitat.
Option 3, is correct
The virus needs to speak the molecular language of cells. This is how he manages to dominate and enslave them so that they become factories for new viruses, producing the proteins that the infectious agent requires to assemble its descendants. If this conversation is not fine-tuned, even if the virus has the key and enters, it is doomed to failure.
<h3>Why does a virus lethal to us not infect animals?</h3>
For a virus to be able to enter a cell, it must have the right key. And this key, which are the proteins on the surface of viruses, has to enter the correct lock, the receptors that are on the cell membrane. Cells are actually houses with many different doors and locks. Some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.
With this information, we can conclude that some viruses have keys that open the lock of any cell and any kind of host, and others do not, so the infection caused by viruses is specific.

A simple or closed fracture does not break the skin. This is further explained below.
<h3>What is a closed fracture?</h3>
Generally, a closed fracture is simply defined as a situation whereby the skin hasn't been damaged, even if the bone is cracked.
In conclusion, If the fracture is simple or closed, no blood will be seen on the skin. More detail about this is provided below.
