What happens if a spike protein changes shape
Answer:
When a spike protein changes its shape, it folds on itself and merges its membrane within our cell's membrane to allow itself a way in, causing an infection and the penetration of host cells.
When a spike protein changes shape, it can affect the way a virus interacts with its host cell.
What is a spike protein?The spike protein is a key component on the surface of some viruses, such as coronaviruses, and is responsible for binding to host cell receptors, allowing the virus to enter the cell and cause infection.
If the spike protein changes shape, the following can happen:
Altered binding affinity: The ability of the spike protein to bind to host cell receptors may be enhanced or diminished. This can potentially affect the transmissibility or infectiousness of the virus.
Immune system evasion: A change in the spike protein shape might make it harder for the host's immune system to recognize the virus, potentially allowing the virus to evade detection and neutralization by antibodies.
Impact on vaccines: Changes in the spike protein shape could also impact the effectiveness of vaccines designed to target the original spike protein, as the altered shape may not be recognized as effectively by the immune system.
Overall, when a spike protein changes shape, it can have various consequences for viral transmission, immune system response, and vaccine effectiveness.

Answer:
1. EUGLENA1. Are euglena unicellular or multicellular?= Euglena are unicellular organisms classified into the Kingdom Protista, and the Phylum Euglenophyta.
2. What Kingdom do euglena belong to? What Phylum?= Euglena belongs to Kingdom Protista and the Phylum Euglenophyta.
3. What organelle carries out photosynthesis?= Chloroplasts carries out photosynthesis.
4. On which end is the flagellum located?= The flagellum is located on the anterior (front) end, and rotates in such a way as to pull the cell through the water.
5. Define autotrophic.= Autotrophs are known as producers because they are able to make their own food from raw materials and energy.
6. Define heterotrophic.= Heterotrophs are known as consumers because they consume producers or other consumers.
7. Describe the two ways in which the euglena get their nutrients. Euglena can gain nutrients by sunlight absorbing them across their cell membrane.All Euglena have chloroplasts and can make their own food by photosynthesis in which they get nutrients. 8. What is the eyespot used for?= Euglena have an eyespot at the anterior end that detects light, it can be seen near the reservoir. This helps the euglena find bright areas to gather sunlight to make their food.
9. What is the function of the nucleus?= The function of the nucleus is it contains the cell's DNA and controls the cell's activities. The nucleolus can be seen within the nucleus.
10. What is the function of the contractile vacuole? What would happen if the cell did not have this organelle.= The function of the contractile vacuole is that, it helps the cell remove excess water. If the cell did not have this organelle, the euglena could take in some much water due to osmosis that the cell would explode.

If unicellular organism swims from a hypertonic to an isotonic environment, will its contractile vacuole becomes more or less active?
When a unicellular organism swims from a hypertonic to an isotonic environment, its contractile vacuole becomes less active.
What is an Hypertonic solution?A hypertonic solution is one in which the concentration is greater than the surrounding environment.
An Isotonic solution is one in which the concentration is equal to that of the surrounding environment.

Bones and fascia
d.
The pulmonary and systemic circuits
Answer:
A
the answer is A!!! good luck <3
Answer:
A. Bones, joints, and connective tissue
Explanation:
The skeletal system supports and protects the body while giving it shape and form. It is composed of bone, joints, ligaments, connective tissue, and cartilage.
Organs are not included, for they are not skeletal. Fascla is a sheet of connective tissue beneath the skin that attaches to, stabilizes, encloses, and separates muscles and other internal organs. It is not part of the skeletal system.
A systemic circuit is the path of circulation between the heart and the rest of the body. It too, is not skeletal.
Hence, the answer is A.
