Answer: It is b multiple alleles
Explanation: Alleles determine your genes.
Answer: atoms come from originally....The first source was the BIG BANG that created the Universe 14 billion years ago. When the big bang occurred, the elementary particles initially were too hot initially to make any stable atoms... but after a few thousand years, when things cooled down a lot, Hydrogen and Helium got made.
Answer:
Arp2/3 and formins differ in their mechanisms of actin polymerization
Explanation:
The actin cytoskeleton plays key roles in diverse cellular processes including, among others, morphogenesis and endocytosis. The Arp2/3 complex and formin family proteins are two different types of actin-binding proteins capable of modulating the dynamics of actin filaments. The Arp2/3 complex is well known to have a key role in spine morphogenesis by promoting the branching of existing actin filaments. On the other hand, formin proteins induce the formation of plasma membrane protrusions by promoting the formation of unbranched filaments.
The organelles that receive the directions from the DNA in the nucleus to make proteins are ribosomes.
