A mouse has a greater ratio of surface area rather than a hippopotamus.
Answer:
Xylem
Explanation:
Water moves from the roots to the leaves through tissue called the xylem, in a process called transpiration. As water evaporates out of the leaf, more water is 'pulled upwards' to replace what has been lost.
Answer:
Hmm.
Explanation:
The ocean is the dominant physical feature on our planet Earth, covering approximately 70% of the planet's surface.
Answer:
No, CREs usually don't account for differences in gene expression levels.
Explanation:
<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.
Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.
Fish don't have ears we can see but they have ear parts inside their heads. They pick up sounds in water through their bodies.
