There are some exceptions to the rule organisms such as a protist called a euglena can be both heterotrophic and autotrophic. This is a true statement.
Explanation:
- Euglena is a large genus of unicellular protists: they have both plant and animal characteristics
- Photoautotrophs include protists that have chloroplasts, such as Spirogyra. Heterotrophs get their energy by consuming other organisms. Other protists can get their energy both from photosynthesis and from external energy sources
- All live in water and move by means of a flag ellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants
- Euglena is photosynthetic in the presence of sunlight i.e autotrophic, when deprived of sunlight they behave like heterotrophs by predating on other smaller organisms.
- Most species of Euglena have photosynthesizing chloroplasts within the body of the cell, which enable them to feed by autotrophy, like plants. They can also take nourishment heterotrophically, like animals.
Answer:
a. NH gain a proton
b. NH is a Bronsted-Lowry base because is capable of accepting a proton
Explanation:
Answer:
1.41 g of H₂O
Solution:
The equation for given reaction is as follow,
Cu₂O + H₂ → 2 Cu + H₂O
According to equation,
127 g (2 mole) Cu is produced along with = 18 g (1 mole) of H₂O
So,
10 g Cu produced will generate = X g of H₂O
Solving for X,
X = (18 g × 10 g) ÷ 127 g
X = 1.41 g of H₂O
science of love
,EXPLANATION:
The initial happy feelings of being in love is stimulated by 3 chemicals in the brain: noradrenaline that stimulates adrenaline production causing that racing heart and sweaty palms; dopamine, the feel-good chemical; and phenylethylamine that is released when we're near our crush, giving us butterflies in our tummies.

Answer:
The rock displaces 475 mL of water.
475 mL is the volume of the rock.
1 mL = 1 cm^3
The mass is just density times volume.
m = 475 * 2.5 = 125 g
