Answer:
Euglena is a single celled organism. It belongs to Kingdom Protista. Euglena is a eukaryotic organism that exhibit characteristics of both plants and animals. Some species of Euglena are photoautotrophs like plants which means they have ability to trap sunlight to produce food by the process of photosynthesis. Whereas, some species are heterotrophs like animals which means they obtain food by feeding on other organisms.
If scientists remove all of the chloroplasts from a Euglena, it will not be able to perform photosynthesis because chloroplast is an organelle that contains light sensitive pigments named as chlorophyll. Chlorophyll traps light energy from sun. Sunlight energy, along with carbon dioxide and water produces food in the form of glucose in plants and other photoautotrophs.
Answer:

a). Privacy: The privacy of the subject involved in the research should be maintained.
b). the subject must be allowed to the minimal exposure to risks and it must be tested on animals first to avoid deaths.

Answer:
F,T,T,F
Explanation:
1)false-(its a covalent bond)
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
2)True-(water is a polar molecule)
Water is a polar molecule because the positive end attracts particles of negative charge.
3)True
water dissociates to form hydrogen ions (H3O+) and hydroxide (OH-) ions
4)false
Lower pH number means stronger acid, higher pH number means stronger base.
Answer:
it should be 4:4
Explanation:
The p will stand for purple and the w will stand for white.
it would go like P | P
W | PW | PW
W | PW | PW
Answer:
The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer.
