After Sharon stares at a patch of saturated green color for a brief period of time, she looks at a white surface and sees a red

natima [27]

Answer:

opponent-process theory

Explanation:

Based on the information provided within the question it can be said that this perceptual phenomenon is best explained by the opponent-process theory. This theory explains that when one color pair is activated it triggers activity from another pair, meaning that the three opposing color pairs ( blue/yellow, red/green, and black/white) are all linked together. Which is why Sharon saw red when looking at a white surface.

Select all the correct labels on the image.

valkas [14]

The diagram is not given in the question, so the diagram is attached below.

Answer:

chloroplast, thylakoid space

Explanation:

The photosynthesis process is categorized in two steps light-dependent reactions and light-independent reactions.

In light-dependent reaction, chlorophyll absorbs one photon and loses one electron. This initiates the flow of electrons down an electron transport chain and result into reduction of NADP to NADPH.

Along with this, it creates a proton gradient or concentration across the chloroplast membrane and into the thylakoid space. The proton concentration or energy gradient is then used by ATP synthase for the synthesis of ATP and cellular respiration.

Hence, the correct answer is chloroplast and thylakoid space

Imagine that a doctor is culturing two types of cells: one from a malignant melanoma and one from a normal skin sample. How woul

Lynna [10]

Answer:

Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.

Explanation:

Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.

In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.

A hypothesis is a general principle or explanation that is derived from observations. Suppose you make the following observation

mr_godi [17]

Question continued

For each statement below, mark "True" if it would be a valid hypothesis, based on these three observations alone, and mark "False" if it would not be a valid hypothesis.

1. The onion cells I looked at have a nucleus.

2. All onion cells have a nucleus.

3. All cells have a nucleus.

4. Some cells have a nucleus.

5. Only onion cells have a nucleus.

6. If I look at 10 skin cells from my hand, each one will have a nucleus.

Answer:

1. The onion cells I looked at have a nucleus. false - this is not a hypothesis, it is an observation of the evidence you collected.

2. All onion cells have a nucleus. true - this is a valid hypothesis based on the evidence you have gathered from looking at onions

3. All cells have a nucleus. true - this is a hypothesis based on you looking at 3 cell types, several samples of each, and finding that they all have a nucleus

4. Some cells have a nucleus. false - this is not a valid hypothesis. Your evidence so far suggests all cells have a nucleus

5. Only onion cells have a nucleus. - false, you know this to be false as other cell types you analysed had a nucleus

6. If I look at 10 skin cells from my hand, each one will have a nucleus. false - a hypothesis is supposed to be a general principle that is backed up by evidence, this is too specific.
