Most
reptiles and all birds are oviparous, meaning that their young develop in
fertilized eggs laid outside the mother's body. In contrast, most mammals are
viviparous, meaning that their young develop inside the mother's body.
<span>
The
main difference between these two groups is that oviparous animals do not
undergo any embryonic development inside the mother whereas viviparous do.</span>
Answer:b.are required for the expression of specific protein-encoding genes
Explanation:
Transcription factors are proteins that bind to enzyme RNA polymerase to aid transcription( coping of information on DNA to an intermediate mRNA.
They control the expression of a particular gene. A transcriptor can be a repressor or enhancer. A repressor when they inhibit the action of RNA polymerase by blocking it from attaching to promoter sequence or enhancer by binding to RNA polymerase to enhance transcription.
Transcriptor protein can work alone or work with other protein such as silencer.
I think the answer is p wave on the penn foster test
I believe the answer you are looking for is
A) true
So that they don't argue over results when two types of measurements equal the same thing but are just put differently
