Answer:

Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.

Scientists use observation to collect and document records, which permits them to assemble after which test hypotheses and theories. Scientists have a look at in lots of approaches – with their personal senses or with gear which include microscopes, scanners or transmitters to increase their imaginative and prescient or listening to.

Stolb23 [73]

Answer:

option B: one species decreases the probability that a second species will become established

Explanation:

Inhibition as a mechanism of succession occurs when some early species which could also include pioneer species make the site less suitable for the development of other species and do not allow them to become established and grow. When eventually these early species die, other species that were hindered will subsequently grow and become established gradually giving rise to a climax community.

Glycogen Synthase Kinase:_______.

horrorfan [7]

Answer:

A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.

Explanation:

Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.

Explain how a crime lab could use paper chromatography to determine if lipstick found at a crime scene matched the lipstick of a

FromTheMoon [43]

Explanation:

The lipstick from the crime would be crushed and dissolved in an appropriate liquid solvent. The lipstick would then be placed in one of the ink spots on the starting / base line of the paper. Another spot would be created for the lipstick with which it is being compared with.

The paper chromatogram would then be placed vertically on a solvent that acts as the mobile phase. After some time, when the solvent reaches the solvent front of the paper chromatography, by capillary action, the chromatogram can be removed and left to dry.

Bands will have appeared on the chromatography paper formed from the different components of the lipstick. The bands of the lipstick from the crime scene and that with which it is being compared to are observed. If the bands are all aligned, horizontally, then this means it is a complete match. The lipstick must have been the same used at the crime scene.
