Question 20 (1 point)
How does the euglena differ from the paramecium?



Question 20 options:

Euglena are photosynthetic.


Paramecia use flagella to move.


Paramecia have an "eye spot" to detect light.


Euglena have both a macronucleus and a micronucleus

Question 21 (1 point)
Which organism is likely to live on the stump of a dead tree in a cool, moist, shady forest?

Question 21 options:

Diatoms


Euglena


Mushrooms


Paramecium

Question 22 (1 point)
Compare this fungus with the protist shown in the images below. How do they differ in the way they obtain nutrients?



Question 22 options:

Both organisms are autotrophs. The mushroom uses hyphae to get its nutrients and the amoeba uses the pseudopod instead.




Both organisms are consumers. The amoeba engulfs its food with it;s pseudopod, while the fungus absorbs food from the dead leaves using its hyphae.




The amoeba is a producer and obtains nutrients through photosynthesis; the fungus is a consumer and is decomposing leaf litter in the forest.



Question 23 (1 point)
Euglena, amoeba, paramecium: all one-celled protists. How does the amoeba move through its environment?

Question 23 options:

cilia


flagellum


pseudopod


hyphae

Explanation:

The answer is the amoeba. because amoeba relies on hiding by mimicking exceptible cells in a plant..

Rock pocket mice live in the deserts of the American southwest. Ancestral pocket mice all had light-colored coats that blended in
with the region's rocks and sandy soil, keeping the mice hidden from predatory owls. About 1.7 million years ago, a series of
volcanic eruptions spewed out wide trails of black lava into the middle of rock pocket mouse territory. Currently there are two color
morphs of rock pocket mice: light-colored mice that are typically found in habitats with sandy soil, and dark-colored mice that are
typically found in habitats with dark-colored lava rocks.
Which of the following best justifies the claim that alleles that may be adaptive in one type of environment can be deleterious in
another because of different selective pressures?

what is the non-native species doing to damage our new environment​
