Environmental factors that can influence gene expression can be internal or external.
True or false
Answer:
True!
Explanation:

Answer:
Two atoms slam together to form a heavier atom.
Explanation:
Fusion occurs when two atoms slam together to form a heavier atom, like when two hydrogen atoms fuse to form one helium atom. This is the same process that powers the sun and creates huge amounts of energy—several times greater than fission. It also doesn’t produce highly radioactive fission products.
Why is heritable variation important for both artificial and natural selection.
Answer:
Heritability is important for natural and artificial selection because a trait must be heritable for them to take place. ... Variations that exist in every population are the basis for natural selection. The differences in organisms come from different genetic material.

What is the average velocity of the skier in the image
Answer:
210 m
Explanation:
just look at the image ad you will see
The average velocity is 46.67m/s
What is average velocity?average velocity is just the common pace with a path. If an experience starts and ends on the identical point, the full displacement is 0, so the average velocity is zero.
AVERAGE VELOCITY:-total displacement /total time taken.
total time= 3 min
total displacement AD = 140 m
∴average velocity = 140/3
= 46.67m/s.

identify the three domains and the different groups or kingdoms within each domain (marine science)
Answer:
The three domains are the Archaea, the Bacteria, and the Eukarya.
Explanation:
Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.
The three kingdom domains are Eubacteria, Archaea, and Eukarya, and under these three domains there are many other branches, such as the bacteria, which are classified into gram positive and gram negative, etc.
What is the division of the three domains?The three domains are Eubacteria, Archaea, and Eukarya, and Eubacteria is further classified into purple bacteria, gram-positive and gram-negative bacteria, cyanobacteria, green filamentous bacteria, etc., and all the bacteria are prokaryotes in nature. They don't have a nuclear membrane.
The archaea have Methanosarcina, Thermoproteus, etc. The eukarya has subdivisions like animals, plants, fungi, ciliates, etc. All of them have a nuclear membrane that contains the genetic material. The cell wall composition of fungi differs from that of plants. The cell membrane composition of multicellular animals is different from the cell membrane of the unicellular slime mold.
Hence the three domains are Eubacteria, Archea, and Eukarya, which are further subdivided.
