The most likely answer to your question would be (3) gene expression being affected by the environment. 

This is the correct answer because these two species had each different environmental influences where one had enough light, the other didn't. Because this difference was apparent, the genetic potential that both of the species shared eventually manifested into something different. Intensely colored wings for some butterflies and paler wing colors for other butterflies.

These photosynthetic protists produce one third of the Earth’s oxygen that is generated through photosynthesis.
STALIN [3.7K]
<h2>Answer:  C) Algae</h2>

Explanation:

By process of elimination:

  • moss is a plant belonging to the Bryophyta division. It is not a protist
  • paramecia are animal-like protists that don't generally photosynthesize
  • protozoans feed on organic matter such as other microorganisms or organic tissues and debris (not autotrophic)
  • This leaves Algae, which are autotrophic protists.

What are three functions of a starfish's water vascular system?
olchik [2.2K]

The water vascular system of a sea star enables movement, digestion and respiration through the use of water to exert force on limbs known as tube feet. The vascular system is primarily water but also contains coelomocytes, protein and potassium salts.

Which level of life includes all of the other levels in this list: organisms, cells, biosphere, molecules, ecosystems?
Vladimir79 [104]

Answer:

Biosphere

Explanation:

The biosphere is the part of the earth that supports life forms. It includes hydrosphere, atmosphere, and lithosphere. Various ecosystems, aquatic or terrestrial, are present in the biosphere. Biotic and abiotic components of a geographical region that interact with each other together make an ecosystem.

The biotic component of an ecosystem includes all the organisms present in it. Organisms may be unicellular or multicellular. All the organisms are made up of one or more cells. Cells are made up of various biomolecules that interact and enable cells to perform the life processes.

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here
