Answer:
ion
Explanation:
The atom then loses or gains a "negative" charge. These atoms are then called ions.
Answer:
A. Cyclins
Explanation:
Cyclins are group of related proteins and are the most important core cell cycle regulators. Each cyclin is associated with a particular transition or phase in the cell cycle and helps drive the events of that phase or period by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks).
Cdks are kinases, enzymes that phosphorylate (attach phosphate groups to) specific target proteins. The apg acts like a switch, making the target less active or to have more protein. When cyclin attaches to Cdk, it can activate the Cdk as a kinase and can directs also the Cdk to a specific set of target proteins. For example, G1/S cyclins send Cdks to S phase targets (e.g., DNA replication), while M cyclins send Cdks to M phase targets (e.g.,breakdown of the nuclear membrane ).
Life science would be naming, classifying organisms.
Answer:
<em>A) </em>The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily.
<em> B)</em> The five major hormones are: gastrin ( stomach ), secretin ( small intestine ), cholecytokinin (small intestine), gastric inhibitory peptide (small intestine), and motilin (small intestine).
Explanation:
<em>Explanation of answer A):</em>
Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.
Answer:
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide.
