<u>Answer</u>:
Once a human is infected with a virus, bacterium, fungus, or parasite they interfere with the human’s normal body function
.
<u>Explanation</u>:
The infection due to the pathogen are not always end up as a disease. Infection occurs when any pathogen comes inside the human body it can be virus, bacteria or can be fungus, and starts multiplying by getting suitable environment as well as the host. The microbes sometimes challenges the immune system and lowers the resistance power the body. So, as viruses does by killing the fighter cells and also by disrupting the general cell functions.
Hmm. This one’s simple. It’s definitely biodiversity, because if there are lots of organisms, people can fulfill their niches easily. Carbon dioxide and pollution just harms the organisms and salt water doesn’t do much good, except in ocean ecosystems. The answer is C: Biodiversity.
Answer:
( Going from left to right )
- Prophase -
- Telophase & Cytokinesis -
- Anaphase -
- Metaphase -
Explanation:
Prophase - Chromatin condenses making the chromosomes visible.
the nuclear envelope breaks down - makes it look like it has butterflies
Remember: The "PRO-phase" gets -butterflies- when it's about to start a race, but he lost so he starts to have a -break down-.
Metaphase - The chromosomes become aligned at the "center" or equatorial plane.
Remember: metaphase in Greek means "between" and "stage" and during this stage, the chromosomes stop moving back and forth, and also there are kept in the middle of the cell !!
Anaphase - sister chromatids separate and the resultant daughter chromosomes move toward the poles.
Remember: Sister Anna has a twin they both move out of their home and separate. One moves to the north pole and the other lives in the south pole.
Telophase - Daughter chromosomes reach the poles and form two new nuclei.
Remember: Anna and her twin settle in their new homes and both of the sisters throughout the year have two children or "nuclei" each, and also call each other on the "telephone" almost every day. :)

Answer:
Dopamine
Explanation:
Parkinson’s disease is a degenerative, progressive disorder that affects nerve cells in parts of the brain called the basal ganglia and the substantia nigra.
The neurotransmitter dopamine is produced by nerve cells in the substantia nigra and these nerve cells function in relaying information from the brain that plan and control body movement. In Parkinson's disease, the dopamine-producing nerve cells of the substantia nigra begin to die off . Symptoms such as tremor, impaired movement, stiffness, and balance problems occur when the loss of nerve cells is about 80%
