natali 33 [55]

Answer:

1. Kingdom Protista

2. Kingdom Eubacteria

3. Kingdom Archaeabacteria

Explanation:

1. Kingdom Protista is one of the the six kingdoms. It consists of organisms called PROTISTS that are eukaryotic i.e. possess a membrane-bound nucleus and mostly single-celled (unicellular). Protists are eukaryotic organisms like plants, animals and fungi but their characteristics do not fit into any of these three eukaryptic groups. Protists include; algae, amoeba, etc.

2. Kingdom Eubacteria, as their name implies, are known as true bacteria. The constituent organisms of this kingdom are prokaryotic i.e. lack a membrane-bound nucleus and single-celled (unicellular). They possess a cell wall, in addition to their cell membrane, that is made up of PEPTIDOGLYCAN. Examples of organisms in this kingdom are Streptococcus, Bacillus etc.

3. Kingdom Archaebacteria were once grouped together with the true bacteria as kingdom Monera but were split because of their obvious differing characteristics. Archeans are single-celled prokaryotic organisms characterized majorly by their ability to live and thrive in extreme environmental conditions e.g hot conditions, anoxia conditions (no oxygen).

_______ research has the potential to significantly impact the development of disease-modifying treatments for Parkinson's disea
nydimaria [60]

<u>Stem cell </u>research has the potential to significantly impact the development of disease-modifying treatments for Parkinson’s disease with considerable progress made in creating dopamine-progressing cells.

Explanation:

Parkinson’s disease, a neurodegenerative disease, leads to reduction of dopamine (a neurochemical messenger which carries messages involving thinking and body movements to brain) in the body because the disease will target and kill dopamine-producing nerve cells (neurons). This leads to loss of movement and thinking abilities which are activated by dopamine.

Stem cells research is done to study about the prospects of stem cells in stem cell therapy for Parkinson’s patients as a viable source of new dopamine nerve cells. Research has been involved in growing stem cells to replace or regenerate dopamine-producing nerve cells by using embryonic stem cells or induced pluripotent stem cells as a treatment modality in Parkinson’s disease.

Choose an activity that you, your family, or a friend engages in and which results in pollution. Discuss some of the ethical, ec
VMariaS [17]

An activity that me, my family or friends engage in that causes pollution is the use of vehicles that run on fossil fuels for transportation.

<u>Explanation:</u>

Fossil fuels contribute to pollution in a large way. Burning of fossil fuels release gases like carbon dioxide, carbon monoxide, oxides of sulphur, nitrogen etc which accelerate pollution. Petrol and diesel are the common fossil fuels used in vehicles.

Easy transportation is the necessity that makes people chose this alternative. There are other alternatives to fossil fuels. Vehicles can use cleaner fuels like CNG and LPG.  

The vehicles can also be powered by electricity. But switching to these alternatives has some limitations as well which makes people find it difficult some times. It would never be a simple matter to sop this activity considering how important fast transportation is in this era.

nata0808 [166]
There are more possible answers here. 

What we measure in experiments are called observables or variables. 

By saying observable or a variable, you're talking about one aspect of one general characteristic of an object. Imagine measuring the length of a leaf. Your variable would be length, which is a characteristic of your object (leaf).
